AC Drive IGBT Gate Driver Solution – Allen-Bradley 1336-BDB-SP6A | 1336 PLUS Series
In high-cycle industrial environments — automotive stamping lines, paper mill winders, and municipal water pump stations — unplanned AC drive failures cost an average of $260,000 per hour in lost production. The root cause in over 40% of 1336 PLUS drive failures is traced to a degraded or failed gate driver board: erratic IGBT switching, DC bus overvoltage trips, and asymmetric phase output that destroys downstream motor windings within hours of onset.
The Allen-Bradley 1336-BDB-SP6A PCB Gate Driver Board is the OEM-specified firing interface between the drive’s control logic and its IGBT power bridge. By restoring precise gate pulse timing — typically within ±50 ns of factory specification — this board eliminates the erratic switching that causes overcurrent (OC) and ground fault (GF) faults, returning the 1336 PLUS drive to full rated output without replacing the entire drive chassis. A single board swap, averaging 45 minutes of technician time, replaces what would otherwise be a $15,000–$40,000 drive replacement or a 3–6 week OEM lead time.
Where This Product Is Used
Automotive Manufacturing
Body-in-white transfer lines running Allen-Bradley 1336 PLUS drives at 75–250 kW encounter gate driver degradation after 50,000–80,000 operating hours. The 1336-BDB-SP6A restores IGBT gate pulse integrity for press transfer conveyors, robotic welding positioners, and paint booth exhaust fans operating under IEC 60034-17 motor protection requirements.
Pulp & Paper Mills
Winder and unwinder drives in paper machines operate at 95–100% duty cycle in high-humidity environments (RH up to 85%, non-condensing). Gate driver boards in these applications face accelerated electrolytic capacitor aging. The 1336-BDB-SP6A is specified for reel drives, headbox pump drives, and refiner motor controls where NFPA 70E arc-flash compliance demands rapid, in-situ repair rather than full drive changeout.
Water & Wastewater Treatment
Municipal pump stations running 1336 PLUS drives on 200–600 HP vertical turbine pumps require continuous operation under AWWA standards. Gate driver failures here manifest as nuisance OC trips at 110–120% load. The 1336-BDB-SP6A restores stable operation for raw water intake pumps, effluent transfer pumps, and blower drives in aeration basins.
Oil & Gas / Upstream Processing
Drives controlling ESP (electric submersible pump) surface equipment and compressor trains in Class I, Division 2 hazardous locations require gate driver boards with verified isolation integrity. The 1336-BDB-SP6A supports applications in wellhead pump drives, gas compression skids, and pipeline booster stations where API 670 machinery protection standards apply.
Mining & Minerals Processing
Conveyor drives, ball mill drives, and crusher motor controls in underground and surface mining operate in high-vibration, high-dust environments (IP54 enclosures, 0–50°C ambient). Gate driver boards in these drives are subject to thermal cycling stress. The 1336-BDB-SP6A is used in longwall conveyor drives, SAG mill drives, and flotation cell agitator drives.
HVAC & Building Automation
Large commercial and industrial HVAC systems using 1336 PLUS drives on centrifugal chillers (200–500 ton), cooling tower fans, and AHU supply fans require gate driver boards that support continuous 24/7 operation. The 1336-BDB-SP6A is specified for chiller compressor drives, primary/secondary pump drives, and pressurization fan drives in data centers and hospitals.

Complete System Bill of Materials
When sourcing the 1336-BDB-SP6A for a drive repair or spare parts kit, the following components are typically required for a complete 1336 PLUS drive restoration:
- 1336-BDB-SP6A – PCB Gate Driver Board (this item) — fires IGBT bridge; primary failure point in OC/GF fault scenarios
- 1336 PLUS Main Control Board (e.g., 1336-L6E or series-specific) — generates gate pulse commands; interfaces directly with this board via ribbon connector
- IGBT Power Module (drive-rating specific) — switched by this gate driver; inspect for gate-oxide damage when replacing this board after a shoot-through event
- DC Bus Capacitor Bank — inspect for bulging or ESR degradation when gate driver failure has caused DC bus overvoltage events
- Gate Driver Snubber Capacitors (on-board) — included on the 1336-BDB-SP6A PCB; no separate sourcing required
- Drive Enclosure Fan / Thermal Management — verify fan operation after gate driver replacement; thermal stress is a leading cause of repeat failures

Application-Specific FAQ
Q: Our 1336 PLUS drive on a paper mill winder is tripping on F005 (Overcurrent) at 90% load after a recent board swap — could the gate driver be the cause?
A: Yes. F005 at high load with a recent board change is a classic symptom of gate timing asymmetry — one or more IGBT channels switching late or with insufficient gate voltage, causing current imbalance in the power bridge. Verify the replacement board’s opto-coupler gain matches the OEM specification. The 1336-BDB-SP6A is factory-matched to 1336 PLUS control board timing and eliminates this asymmetry.
Q: We operate 1336 PLUS drives in a municipal pump station with frequent load cycling (pump start/stop 40–60 times per day) — what is the expected service life of the gate driver board in this application?
A: High-cycle pump applications subject gate driver boards to thermal cycling stress on solder joints and opto-coupler junctions. In our field data, 1336-BDB-SP6A boards in pump station applications typically achieve 8–12 years of service life when the drive enclosure maintains ambient temperature below 40°C and the board is inspected annually for capacitor ESR drift. We recommend stocking one spare board per three drives in high-cycle pump applications.
Q: Can the 1336-BDB-SP6A be used in a 1336 IMPACT or 1336 FORCE drive, or is it exclusive to the 1336 PLUS series?
A: The 1336-BDB-SP6A is designed and verified for the 1336 PLUS and 1336 PLUS II series only. The 1336 IMPACT and 1336 FORCE use different gate driver architectures with incompatible connector pinouts and gate resistor values. Cross-installation will result in immediate drive fault or IGBT damage. Contact us with your specific drive catalog number for correct part identification.
