Overview
The Littelfuse SJ6012R2TP is a silicon-controlled rectifier (SCR) from the SJxx12xx series, designed for high junction temperature applications. It features a 600V repetitive peak off-state voltage and an RMS on-state current rating of 12A at a case temperature of 135°C. The device utilizes a TO-220R non-isolated package with a three-terminal configuration. Key electrical characteristics include a maximum gate trigger current of 10mA and a gate trigger voltage of 1.5V. It supports a peak non-repetitive surge current of 120A at 60Hz and operates within a junction temperature range of -40°C to 150°C.
Feature Summary
- Capable of operating at high junction temperatures up to 150°C
- Sensitive gate design allows triggering with low gate currents
- Halogen-free and RoHS compliant construction
- High surge current capability for demanding switching environments
Applications
- Phase control in heating systems
- Motor speed controls
- Capacitive discharge ignition systems
- Inrush current control circuits
Procurement Notes
Verify the specific ordering suffix against the manufacturer's datasheet to confirm package type and gate sensitivity parameters. Ensure that the procurement documentation explicitly references the SJ6012R2TP part number to avoid confusion with similar variants in the SJxx12xx family. Cross-reference technical specifications directly with official Littelfuse resources prior to integration.
Selection Notes
Select this component when designing uni-directional switch applications requiring robust performance under high thermal stress. The 12A RMS rating and 600V blocking voltage make it suitable for moderate power AC/DC conversion tasks. Consider the TO-220R package dimensions for mechanical fit and ensure adequate heat sinking to maintain junction temperatures within the specified operational limits during continuous conduction.
Part Context
This device belongs to the SJxx12xx series of high junction temperature SCRs manufactured by Littelfuse. The series offers various voltage ratings and package options to accommodate different circuit requirements. The SJ6012R2TP specifically denotes the 600V variant with standard gate sensitivity housed in a TO-220R leaded package, providing a balance of electrical performance and thermal management capabilities.
Replacement Considerations
Consult the official Littelfuse SJxx12xx datasheet for verified substitute part numbers. Direct replacements must match the 600V voltage rating, 12A current capacity, and compatible gate trigger characteristics to ensure circuit functionality without modification.
