Overview
The Littelfuse SJ6040N2RP is a high-temperature silicon-controlled rectifier (SCR) from the SJxx40xx series, designed for uni-directional switching applications. It features a 600 V repetitive peak off-state voltage and handles a 40 A RMS on-state current at a case temperature of 115°C. The device utilizes a TO-263 (D2PAK) surface-mount package with a low gate trigger current of 15 mA maximum at approximately 1.5 V. It supports an operating junction temperature range of -40°C to +150°C and offers a peak non-repetitive surge current capability of 520 A at 60 Hz.
Feature Summary
- High thermal stability enabling operation up to 150°C junction temperature
- Low gate sensitivity requiring minimal trigger power
- Robust surge handling capacity for overload protection
- Surface-mount D2PAK design for automated assembly
Applications
- AC rectifier circuits
- Voltage regulators
- Phase control in heating systems
- Motor speed controls
- AC solid-state switches
Procurement Notes
Verify the specific suffix 'N2RP' corresponds to the 600V rating, 15mA gate sensitivity, and TO-263 reel packaging configuration. Confirm RoHS compliance and halogen-free status requirements against the latest Littelfuse datasheet revision before finalizing orders.
Selection Notes
Select this component when high junction temperatures are expected or cooling is limited. Ensure the application voltage does not exceed 600V and that the average current remains within derating curves. Verify PCB footprint compatibility with the TO-263 package dimensions provided in the mechanical specifications.
Part Context
This part belongs to the SJxx40xx family of 40 Amp standard high-temperature SCRs. The '60' indicates the 600V blocking voltage, '40' denotes the 40A current rating, 'N' specifies the TO-263 package, '2' represents the 15mA gate sensitivity, and 'RP' indicates the reel packing mode.
Replacement Considerations
Direct replacements include other SJxx40xx variants with matching voltage and current ratings, such as SJ4040N2RP (400V). Cross-package alternatives like SJ6040L2TP (TO-220) require thermal and mechanical adaptation.
