Compatible Replacement & Equivalent Models
The following models are electrically compatible or functionally equivalent to the SKKT106/16E. Always verify pinout, package dimensions, and thermal ratings before substitution.
- Semikron SKKT106/14E — Same package, 1400 V rating; suitable for lower-voltage applications
- Semikron SKKT106/18E — Uprated to 1800 V; direct drop-in for higher-voltage environments
- Semikron SKKT132/16E — Higher current (132 A), same voltage; use when derating is required
- Vishay VS-SKKT106/16E — OEM-equivalent from Vishay; same SEMIPACK® 2 footprint
- IXYS MCC162-16IO1 — Functionally equivalent SCR/Diode module, 1600 V / 160 A; verify gate drive compatibility
- Infineon TT106N16KOF — Comparable thyristor module, 1600 V / 106 A; different package — adapter plate may be required
- Powerex R6020625PSYA — Equivalent function; confirm mounting hole pattern before use

System Compatibility
The SKKT106/16E is compatible with the following drive and control platforms (as a power stage replacement component):
- Siemens SIMOREG DC-MASTER series
- ABB DCS800 / DCS550 DC drive series
- Eurotherm / Schneider Electric DC590+ series
- Emerson / Control Techniques Mentor MP series
- Custom-built SCR bridge rectifier assemblies
Always confirm the original module’s voltage class and current rating against your system’s nameplate data before ordering.
Selection Guide
Use the following criteria to select the correct SKKT-series module for your application:
- Step 1 — Voltage Class: Select VDRM ≥ 2× peak line voltage. For 690 V AC systems, minimum VDRM = 1600 V → SKKT106/16E is correct.
- Step 2 — Current Rating: IT(AV) must be ≥ load current with 20–30% derating margin. For 80 A load → SKKT106/16E is appropriate.
- Step 3 — Thermal Budget: Verify heatsink thermal resistance. Rth(j-c) = 0.30 K/W; total Rth(j-a) must keep Tj ≤ 125°C at maximum ambient.
- Step 4 — Package Fit: Confirm SEMIPACK® 2 footprint and M6 screw terminal compatibility with your busbar layout.
- Step 5 — Gate Drive: Ensure gate trigger pulse ≥ 150 mA / 3 µs for reliable turn-on across temperature range.

Replacement & Compatibility FAQ
Q: Can I replace SKKT106/16E with SKKT106/14E?
A: Only if your system line voltage does not exceed 700 V AC. The /14E is rated at 1400 V VDRM, which provides insufficient margin for 690 V systems.
Q: Is the SKKT106/16E interchangeable with SKKT132/16E?
A: Yes, physically and electrically — the /132 is a higher-current variant in the same SEMIPACK® 2 package. It is a safe upward substitution.
Q: Can I use an Infineon TT106N16 as a direct replacement?
A: Electrically similar, but the package and mounting hole pattern differ. A mechanical adapter or custom busbar modification is typically required.
Q: How do I verify authenticity of a Semikron module?
A: Check the laser-etched date code and lot number on the module body. Request a CoC from your supplier. Konmask.com provides full traceability documentation.
Q: What heatsink do I need for SKKT106/16E at full load?
A: At 106 A continuous and 40°C ambient, a heatsink with Rth(h-a) ≤ 0.15 K/W is recommended. Forced-air cooling is advised for continuous full-load operation.
