SCE55AA160

Overview

The SCE55AA160 is a silicon thyristor module from the SCE series, rated for a repetitive peak reverse voltage of 1600 V and an average on-state current of 55 A at a case temperature of 95°C. It features a dual configuration with an isolated package and screw mount installation style. Key electrical characteristics include a maximum gate trigger current of 100 mA, a critical rate of rise of on-state current (di/dt) of 140 A/μs, and a minimum critical rate of rise of off-state voltage (dv/dt) of 1000 V/μs. The module operates within a junction temperature range of -40°C to +130°C.

Feature Summary

• Isolated package design providing enhanced safety and mounting flexibility
• High surge on-state current capability of 1370 A for non-repetitive half-cycle conditions
• Robust dv/dt rating of 1000 V/μs to prevent false triggering in high-noise environments

Applications

• Various rectifier circuits
• Motor drives
• Heater controls
• Static switches

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct pinout and terminal configuration. Confirm that the thermal interface material and mounting torque specifications meet the requirements of the final assembly to maintain the specified thermal impedance and operational reliability under load.

Selection Notes

Select this component for applications requiring a 1600 V blocking voltage and 55 A continuous current handling. Ensure the cooling system maintains the case temperature at or below 95°C to sustain the rated average on-state current. Verify that the gate drive circuit can supply the required 100 mA trigger current without exceeding the peak gate power dissipation limits.

Part Context

This module belongs to the SCE series of discrete semiconductor modules manufactured by SanRex. The series utilizes silicon technology and is designed for power control applications. The SCE55AA160 shares the physical form factor and isolation characteristics with other variants in the SCA/SCE family, differing primarily in voltage and current ratings.
