Overview
The Littelfuse SJ6012DTP is a 12 Amp high junction temperature Silicon Controlled Rectifier (SCR) in the TO-252 (D-Pak) surface-mount package. It features a 600V repetitive peak off-state voltage and a maximum gate trigger current of 20mA at approximately 1.5V. The device supports an RMS on-state current of 12A with a case temperature of 125°C, and handles a non-repetitive surge current of 120A at 60Hz. Operating within a junction temperature range of -40°C to 150°C, it includes UL 1557 recognition as an electrically isolated semiconductor device.
Feature Summary
- High junction temperature capability up to 150°C for robust thermal performance
- Electrically isolated construction recognized under UL 1557 standards
- Low gate trigger sensitivity with maximum current of 20mA
Applications
- Capacitive discharge ignition systems for gas engines
- Strobe light capacitive discharge circuits
- Power tool motor speed controls
- Inrush current control in AC to DC converters
Procurement Notes
Verify the specific ordering suffix against the datasheet part numbering system to confirm the exact voltage rating, gate sensitivity, and packing type. Ensure the procurement specification matches the required electrical parameters and physical dimensions for the intended PCB layout and thermal management design.
Selection Notes
Select this component for uni-directional switching applications requiring high thermal stability and surface-mount convenience. Consider the 12A RMS rating and 150°C junction limit when designing heat sinking solutions. Verify that the circuit's dv/dt and di/dt requirements fall within the specified absolute maximum ratings to ensure reliable operation.
Part Context
This device belongs to the SJxx12xx series of 12 Amp high junction temperature SCRs manufactured by Littelfuse. The series offers various voltage ratings and gate sensitivities across multiple packages, including TO-220, TO-263, TO-251, and TO-252. The SJ6012DTP specifically utilizes the D-Pak package for surface-mount assembly.
Replacement Considerations
Consult the official Littelfuse SJxx12xx datasheet for confirmed substitute part numbers within the same family or equivalent specifications from other manufacturers.
