SCA55AA160

Overview

The SanRex SCA55AA160 is a thyristor module featuring an isolated package design. It supports a repetitive peak reverse voltage of 1600 V and an average on-state current of 55 A at a case temperature of 95°C. The device handles an RMS on-state current of 86 A and a non-repetitive surge current of up to 1500 A at 60 Hz. Key electrical characteristics include a critical rate of rise of on-state current (di/dt) of 140 A/μs and a critical rate of rise of off-state voltage (dv/dt) of 1000 V/μs. The isolation breakdown voltage is rated at 2500 V RMS for one minute.

Feature Summary

Isolated package construction providing electrical safety
High surge current capability for robust operation
Defined thermal impedance for efficient heat dissipation

Applications

Various rectifier circuits
Motor drive systems
Heater control units
Static switches

Procurement Notes

Verify the specific part number against official SanRex documentation to ensure compatibility with your system requirements. Confirm that the mounting torque specifications, ranging from 1.5 to 2.5 N·m for M5 terminals, are strictly adhered to during installation. Check for any updated datasheet revisions that may affect electrical ratings or physical dimensions before finalizing procurement decisions.

Selection Notes

Select this component based on its 1600 V blocking capability and 55 A average current rating under specified thermal conditions. Ensure the application environment allows for a case temperature of 95°C to maintain the rated current capacity. Consider the di/dt and dv/dt ratings when designing snubber circuits to protect the device from transient overvoltages and rapid current changes.

Part Context

This module belongs to the SCA(SCE)55AA series manufactured by SanRex Corporation. It is designed as a compact solution for power electronics applications requiring high reliability and isolation. The series integrates thyristor and diode components within a single insulated housing, facilitating easier integration into industrial power conversion systems.
