SJ4016R1TP

Overview

The Littelfuse SJ4016R1TP is a standard recovery silicon controlled rectifier (SCR) rated for 400 V repetitive peak off-state voltage and 16 A RMS on-state current. It features a forward voltage of 1.6 V, gate trigger voltage of 2 V, and gate trigger current of 35 mA. The device operates within a junction temperature range of -40 °C to +150 °C and is housed in a TO-220AB through-hole package.

Feature Summary

• Standard recovery thyristor construction
• High thermal stability up to 150 °C
• Through-hole mounting configuration

Applications

• Industrial motor control systems
• Power supply circuits
• Lighting dimmer applications

Procurement Notes

Verify the specific suffix 'R1' against official Littelfuse documentation to confirm pinout and mechanical dimensions, as variations exist within the series. Ensure compliance with REACH and RoHS standards by checking the latest manufacturer declarations. Confirm that the TO-220AB package matches the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a 400 V blocking capability and 16 A continuous current handling are required in a through-hole format. The standard recovery characteristic makes it suitable for general-purpose AC switching rather than high-frequency applications. Evaluate thermal management needs given the 150 °C maximum junction temperature limit.

Part Context

This part belongs to the Littelfuse SJxx16xx series of silicon controlled rectifiers. These devices are designed for robust industrial performance, offering reliable switching capabilities in medium-power applications. The series provides standardized electrical characteristics to simplify design integration across various power electronics platforms.

Replacement Considerations

Cross-reference with SJ4016L2TP for alternative gate trigger specifications. Verify compatibility with Q4016NH4TP if bidirectional triac functionality is needed instead of unidirectional SCR operation.
