Overview
The SanRex SCA90AA160 is a thyristor module featuring an isolated package configuration. It supports a repetitive peak reverse voltage of 1600 V and delivers an average on-state current of 90 A at a case temperature of 100°C. The device withstands a surge on-state current of 2100/2300 A and offers a critical rate of rise of off-state voltage of 1000 V/μs. Thermal impedance from junction to case is 0.2 °C/W per chip, with a maximum operating junction temperature range of -40 to +130°C.
Feature Summary
- Isolated package design for enhanced safety
- High surge on-state current capability
- Robust dv/dt rating for noise immunity
Applications
- Various rectifiers
- Motor drives

- Static switches
Procurement Notes
Verify the specific ordering suffix against the manufacturer datasheet to confirm exact electrical characteristics and pinout compatibility. Confirm mounting torque specifications (1.5–2.5 N·m) during installation to ensure reliable thermal contact and mechanical integrity. Check RoHS compliance status if required by your assembly standards.
Selection Notes
Select this component when an isolated thyristor module is required for circuits demanding 1600 V blocking capability and 90 A continuous conduction. Ensure the cooling solution maintains the case temperature at or below 100°C to sustain the rated average current. Verify that the gate trigger requirements align with the control circuitry capabilities.
