Overview
The Littelfuse SJ6012N2RP is a high junction temperature silicon-controlled rectifier (SCR) from the SJxx12xx series, rated for 600 V repetitive peak off-state voltage and 12 A RMS on-state current. It utilizes a TO-263 (D2-Pak) surface-mount package with a non-isolated mounting tab. The device features a sensitive gate trigger requiring a maximum of 10 mA at approximately 1.5 V. It supports a peak non-repetitive surge current of 120 A at 60 Hz and operates within a junction temperature range of -40°C to +150°C.
Feature Summary
- High thermal capability with a maximum junction temperature rating of 150°C
- Sensitive gate design enabling direct interfacing with microprocessors
- Surface-mount construction optimized for automated assembly processes
Applications
- Capacitive discharge ignition systems for gas engines
- Phase control in heating applications
- Motor speed controls and converters/rectifiers
- Inrush current control circuits
Procurement Notes
Verify the specific ordering suffix against the manufacturer datasheet to confirm the exact package variant and packing mode. Confirm that the required gate sensitivity matches the available options for this series. Ensure the procurement documentation references the correct Littelfuse part number to avoid substitution errors during assembly.
Selection Notes
Select this component when a surface-mount SCR with high thermal endurance is required. Verify that the circuit's peak surge currents remain below the 120 A limit at 60 Hz. Ensure the PCB layout accommodates the TO-263 footprint and provides adequate heat sinking for the specified case temperatures.
Part Context
This device belongs to the SJxx12xx family of 12 Amp high junction temperature SCRs. The series offers various voltage ratings and gate sensitivities across multiple package types including TO-220, TO-263, and TO-252. The N2 designation specifically identifies the TO-263 package with 10 mA gate sensitivity.
Replacement Considerations
Cross-reference with other SJxx12xx series parts such as SJ6012R2RP or SJ6012L2RP if different packaging or isolation requirements are needed. Verify electrical parameters match before substituting.
