SJ4012LTP

Overview

The Littelfuse SJ4012LTP is a Silicon Controlled Rectifier (SCR) belonging to the SJxx16xx series, designed for high-temperature environments. It features a rated repetitive off-state voltage of 400 V and an on-state RMS current of 16 A. The device exhibits a forward voltage of 1.6 V, with gate trigger specifications of 1.5 V and 30 mA. It operates within a temperature range of -40 C to +150 C and utilizes a TO-220-2 through-hole package.

Feature Summary

Engineered for high junction temperature operation up to 150 C
Provides robust surge handling capability with non-repetitive on-state current ratings
Utilizes a standard through-hole mounting style for reliable integration

Applications

Industrial power control systems requiring high thermal stability
AC motor drive circuits
General purpose rectification in power supplies

Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm exact electrical tolerances and packaging configurations. Ensure that the ordering information matches the required voltage and current ratings for the intended circuit design before finalizing procurement.

Selection Notes

Select this component when a 400 V blocking voltage and 16 A continuous current capacity are required in a TO-220-2 package. Consider the 150 C maximum operating temperature limit for thermal management planning and ensure the gate trigger requirements align with the driving circuit capabilities.

Part Context

This part belongs to the SJxx16xx series from Littelfuse, which focuses on thyristors capable of withstanding elevated temperatures. The series provides solutions for applications demanding reliable switching performance under harsh thermal conditions compared to standard industrial components.

Replacement Considerations

Consult Littelfuse datasheets for direct cross-reference models within the SJ series or equivalent offerings from other manufacturers that match the 400V/16A/TO-220-2 specification profile.
