SJ4032R2ATP

Overview

The Littelfuse SJ4032R2ATP is a Silicon Controlled Rectifier (SCR) designed for high-temperature environments. It features a TO-263 surface-mount package and supports a maximum repetitive peak off-state voltage of 400 V. The device handles an RMS on-state current of 32 A with a non-repetitive surge current capacity of 350 A. Key electrical parameters include a forward voltage drop of 1.6 V, a gate trigger voltage of 1.5 V, and a holding current maximum of 35 mA. It operates within a temperature range from -40 °C to +150 °C.

Feature Summary

High junction temperature capability for demanding thermal conditions
Surface-mount TO-263 package for automated assembly
Robust surge current handling for inductive loads

Applications

Industrial motor control systems
Solid-state relays
Power supply circuits

Procurement Notes

Verify the specific datasheet revision and ordering suffixes when sourcing. Confirm that the TO-263 footprint matches the target PCB layout. Ensure thermal management strategies align with the component's high-temperature ratings during operation.

Selection Notes

Select this SCR for applications requiring high current density in a compact form factor. Compare the 32 A RMS rating against load requirements. Verify compatibility with existing gate drive circuits regarding trigger voltage specifications.

Part Context

This component belongs to the Littelfuse SJ series of high-temperature SCRs. It shares design characteristics with other models in the family, such as the SJ4032NATP, but differs in specific electrical tolerances and package variations.

Replacement Considerations

Cross-reference with SJ4032NATP for similar performance profiles. Verify pinout compatibility and thermal resistance values before substituting in existing designs.
