SJ6040NTP

Scrs Overview

The Littelfuse SJ6040NTP is a 40 Amp standard high temperature Silicon Controlled Rectifier (SCR) from the SJxx40xx series. It features a rated repetitive off-state voltage of 600 V and a maximum RMS on-state current of 40 A at a case temperature of 115°C. The device utilizes a TO-263 (D2-Pak) surface mount package with a non-isolated mounting tab. Key electrical characteristics include a peak gate trigger current of 40 mA, a peak gate trigger voltage of 1.5 V, and an average on-state current of 25 A. It supports a peak non-repetitive surge current of 520 A at 60 Hz and operates within a junction temperature range of -40°C to 150°C.

Scrs Feature Summary

• High junction temperature capability up to 150°C for robust thermal performance
• Low gate trigger current sensitivity of 40 mA for efficient control circuitry
• Surge current capability up to 520 A at 60 Hz half cycle
• Halogen-free and RoHS compliant construction

Scrs Applications

• AC rectifiers and voltage regulators
• Phase control in heating systems
• Motor speed controls
• Industrial power tools
• Exercise equipment and commercial appliances

Scrs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm the exact package type and gate sensitivity. Ensure that the procurement specifications match the required voltage rating and thermal management requirements for the intended application environment.

Scrs Selection Notes

Select this component based on the 600V blocking voltage and 40A RMS current rating. Consider the TO-263 surface mount package for PCB integration. Verify that the 40mA gate trigger current aligns with the driving circuit capabilities and ensure adequate heat sinking to maintain the junction temperature within the specified operating range.

Scrs Part Context

This part belongs to the SJxx40xx series of 40 Amp standard high temperature SCRs manufactured by Littelfuse. The series includes variants with different voltage ratings (400V or 600V), gate sensitivities (15mA or 40mA), and packages (TO-220 or TO-263). The SJ6040NTP specifically denotes the 600V, 40mA, TO-263 variant.

Scrs Replacement Considerations

Compatible substitutes within the same family include SJ6040LTP (TO-220 isolated) and SJ6040RTP (TO-220 non-isolated). These alternatives share identical electrical ratings but differ in physical package dimensions and isolation characteristics.
