Overview
The Littelfuse SJ6012L1TP is a high junction temperature Silicon-Controlled Rectifier (SCR) in the SJxx12xx series, housed in an isolated TO-220L package. It features a maximum repetitive peak reverse voltage of 600 V and an RMS on-state current rating of 12 A at a case temperature of 110°C. The device supports a peak non-repetitive surge current of 120 A at 60 Hz and has a maximum gate trigger current of 6 mA with a gate trigger voltage of 1.5 V. It operates within a junction temperature range of -40°C to 150°C.
Feature Summary
- High thermal capability with a maximum junction temperature of 150°C for demanding environments
- Electrically isolated mounting tab design recognized under UL 1557 for enhanced safety
- Sensitive gate structure allowing direct interfacing with microprocessors via low trigger current
Applications
- Capacitive discharge ignition systems for gas engines
- Phase control applications in heating elements
- Motor speed controls and AC to DC converters
- Inrush current limiting circuits
Procurement Notes
Verify the specific package variant against the datasheet part numbering system, as the 'L' suffix denotes the isolated TO-220L configuration. Confirm that the 6mA gate sensitivity matches the circuit requirements. Ensure the selected component meets RoHS compliance standards and verify the UL recognition file number E71639 for isolation requirements.
Selection Notes
Select this component when high junction temperature operation up to 150°C is required. The isolated tab is suitable for applications needing electrical separation between the heatsink and the circuit ground. Verify that the 6mA gate sensitivity aligns with the driving logic levels and that the 600V blocking voltage exceeds the peak line voltage plus transients.
Part Context
This device belongs to the SJxx12xx series of 12 Amp high junction temperature SCRs from Littelfuse. The series offers various voltage ratings and gate sensitivities across multiple packages including TO-220L, TO-220R, TO-263, TO-251, and TO-252. The SJ6012L1TP specifically combines the 600V rating with the sensitive 6mA gate trigger in the isolated TO-220L form factor.
Replacement Considerations
Cross-reference other parts within the SJxx12xx series for different voltage or sensitivity options. Check for equivalent SCRs from other manufacturers offering similar 12A/600V specifications in an isolated TO-220L package with comparable thermal resistance and gate characteristics.
