SBB500AA80

Overview

The SBB500AA80 is a thyristor module manufactured by Sanrex Corporation, designed for high-power rectifier control applications. It features an isolated mounting base and supports a repetitive peak reverse voltage of 800 V. The device provides a rated average on-state current of 500 A at a case temperature of 66 °C under single-phase half-wave conditions with a 180° conduction angle. Its maximum RMS on-state current is 785 A, and it withstands a non-repetitive surge on-state current of 9100 A for a half-cycle at 50/60 Hz. The module exhibits a critical rate of rise of on-state current (di/dt) of 200 A/µs and a minimum critical rate of rise of off-state voltage (dv/dt) of 500 V/µs. Thermal impedance from junction to case is 0.085 °C/W.

Feature Summary

Isolated mounting base design
High di/dt capability of 200 A/µs
High dv/dt capability of 500 V/µs

Applications

Various rectifiers
AC/DC motor drives
Heater controls
Light dimmers
Static switches

Procurement Notes

Verify the specific suffix against official documentation to confirm exact ratings, as the series includes variants like the SBB500AA160 with different voltage ratings. Ensure compliance with specified mounting torque values: 2.5–3.9 N·m for the M6 mount terminal and 8.8–10.0 N·m for the M8 main terminals. Confirm thermal management requirements align with the 0.085 °C/W junction-to-case thermal impedance specification.

Selection Notes

Select this component for high-power rectifier control circuits requiring robust isolation and high surge current handling. The 500 A average on-state current rating makes it suitable for heavy-duty industrial loads. Consider the 2500 V isolation breakdown voltage for safety in high-voltage environments. Evaluate the 1.45 V maximum on-state voltage drop for efficiency calculations in continuous operation scenarios.

Part Context

This part belongs to the SBB500AA series of thyristor modules produced by Sanrex Corporation. The series is engineered specifically for high-power rectifier control applications. The SBB500AA80 variant is distinguished by its 800 V repetitive peak reverse voltage rating, contrasting with other series members that may offer higher voltage capabilities such as 1600 V.
