Overview
The Littelfuse SJ6012N2TP is a high junction temperature silicon controlled rectifier (SCR) rated for 600 V blocking voltage and 12 A RMS on-state current. It utilizes a TO-263 (D2-Pak) surface-mount package with a maximum junction temperature of 150°C. The device features a gate trigger current sensitivity of 10 mA, with a maximum gate trigger voltage of 1.5 V. Key electrical parameters include a peak non-repetitive surge current of 120 A at 60 Hz, a critical rate of rise of on-state current (di/dt) of 100 A/µs, and an I²t value of 60 A²s. Thermal resistance from junction to case is specified at 1.1 K/W.
Feature Summary
- High thermal endurance with a maximum junction temperature rating of 150°C
- Surface-mount construction in a TO-263 package for efficient heat sinking
- Low gate trigger current requirement of 10 mA for simplified control circuits
Applications
- Capacitive discharge ignition systems for gas engines
- Strobe light capacitive discharge applications
- Power tool motor speed controls
- Inrush current limiting circuits
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm the exact voltage rating, gate sensitivity, and packaging configuration. Ensure that the procurement documentation references the correct part number format to avoid discrepancies in technical specifications or physical dimensions during integration.
Selection Notes
Select this component for uni-directional switching applications requiring robust thermal performance up to 150°C. The TO-263 package facilitates direct mounting to heatsinks. Designers should ensure the gate drive circuit can supply the required 10 mA trigger current and account for the 1.1 K/W thermal resistance when calculating heat dissipation under continuous load conditions.
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 package types, including through-hole and surface-mount options, designed for industrial and consumer power control environments.
Replacement Considerations
Consult the official Littelfuse datasheet for confirmed substitute part numbers within the same product family. Verify compatibility regarding voltage ratings, current handling capabilities, and package dimensions before implementing any alternative components.
