Overview
The Littelfuse SJ6020N1TP is a silicon-controlled rectifier (SCR) from the SJxx20xx series, designed for high-temperature uni-directional switching applications. It features a TO-263AB (D2-Pak) surface-mount package and supports a maximum repetitive off-state voltage of 600 V with an RMS on-state current rating of 20 A at a case temperature of 130 °C. The device has a sensitive gate trigger level of 6 mA maximum at approximately 1.5 V. It withstands peak non-repetitive surge currents of up to 300 A at 60 Hz half-cycle and 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
- Sensitive gate design allowing direct interfacing with microprocessors
- Internally constructed isolated package for ease of heat sinking
- Halogen-free and RoHS compliant construction
Applications
- Phase control in heating systems
- Motor speed controls
- Capacitive discharge ignition systems for gas engines
- Inrush current controllers
Procurement Notes
Verify the specific ordering suffix against official Littelfuse documentation to confirm the exact package type and sensitivity rating. Confirm compliance requirements such as RoHS and REACH status directly with the manufacturer or authorized distributors before finalizing procurement specifications.
Selection Notes
Select this component when a surface-mount SCR with high thermal endurance is required. Ensure the application's peak current does not exceed the 300 A surge rating and that the gate drive circuit can supply at least 6 mA. Verify that the PCB layout accommodates the TO-263AB footprint and provides adequate thermal dissipation for the 20 A RMS rating.
Part Context
This part belongs to the SJxx20xx series of 20 Amp High Junction Temperature SCRs manufactured by Littelfuse. The series includes variants with different voltage ratings (400 V or 600 V), gate sensitivities (6 mA, 10 mA, or 35 mA), and packages (TO-220L, TO-220R, TO-263). The 'N' designation specifically indicates the TO-263 surface-mount package.
Replacement Considerations
Direct replacements include other SJ6020NxTP variants with matching voltage and sensitivity, or equivalent SCRs from other manufacturers in the TO-263 package with identical 600 V / 20 A / 6 mA gate specifications. Verify pinout compatibility and thermal resistance values.
