SJ4012L2TP

Overview

The Littelfuse SJ4012L2TP is a Silicon Controlled Rectifier (SCR) belonging to the SJxx20xx series, designed for high-temperature industrial applications. It features a rated repetitive off-state voltage of 400 V and an RMS on-state current of 20 A. The device operates within a temperature range of -40°C to +150°C and utilizes a TO-220-2 through-hole package. Key electrical parameters include a forward voltage of 1.6 V, a gate trigger voltage of 1.5 V, and a gate trigger current of 10 mA. The component exhibits a maximum holding current of 35 mA and supports a non-repetitive peak on-state current of 300 A.

Feature Summary

High-temperature operation capability up to 150°C
Robust surge handling with 300 A non-repetitive peak current
Standardized TO-220-2 through-hole mounting

Applications

Industrial power control systems
Motor drive circuits
General purpose AC switching

Procurement Notes

Verify the specific part number against official Littelfuse documentation to confirm availability and lead times. Ensure that the ordering suffix matches the required specifications. Cross-reference distributor listings with manufacturer datasheets to validate authenticity and technical compliance before procurement.

Selection Notes

Select this component based on its 400 V blocking voltage and 20 A continuous current rating. Consider the thermal management requirements for the TO-220-2 package when designing for the upper operating temperature limit. Verify that the gate trigger characteristics align with the driving circuit capabilities.

Part Context

This SCR is part of the SJxx20xx family from Littelfuse, which includes variants such as SJ4020L2TP and SJ4020L1TP. These devices share similar core electrical ratings but differ in specific gate trigger currents and holding currents. The SJ4012L2TP serves as a specialized variant within this high-power thyristor lineup.

Replacement Considerations

Potential substitutes within the same Littelfuse series include SJ4020L2TP and SJ4020L1TP. Verify compatibility by comparing gate trigger current and holding current specifications against the original design requirements.
