Overview
The SJ6025NTP is a silicon-controlled rectifier (SCR) manufactured by Littelfuse Inc. It features a TO-220AB package with three pins and an isolated case connection. The device supports a maximum repetitive peak off-state voltage of 600 V and a root mean square on-state current rating of 25 A. It operates within a junction temperature range from -40 °C to +150 °C. Key electrical characteristics include a gate trigger voltage of 1.5 V, a gate trigger current of 10 mA, and a holding current maximum of 35 mA. The component exhibits a non-repetitive peak forward current capacity of 350 A.
Feature Summary
- High thermal stability enabling operation at elevated temperatures up to 150 °C
- Isolated case construction for secure mounting to heat sinks without electrical shorting
- Robust surge current handling capability for demanding power switching applications
Applications
- Industrial motor control systems requiring high current switching
- Solid-state relays and contactor replacement circuits
- General purpose power regulation and AC power control units
Procurement Notes
Verify the specific suffix NTP against official Littelfuse documentation to confirm pinout configuration and isolation status. Ensure the ordering part number matches the exact electrical ratings required for the target circuit design. Cross-reference datasheet revisions to confirm compliance with current RoHS directives before finalizing procurement specifications.
Selection Notes
Select this component when a 600 V blocking voltage and 25 A continuous current are required in a through-hole package. The isolated case variant is necessary if direct mounting to a grounded chassis is planned. Verify that the gate drive circuit can supply at least 10 mA to ensure reliable triggering under all operating conditions.
Part Context
This SCR belongs to the SJ series of high-temperature thyristors designed for robust industrial environments. The TO-220AB package provides a balance between thermal dissipation and mechanical mounting flexibility. It serves as a discrete solution for medium-power AC control tasks where integrated modules are not feasible.
Replacement Considerations
Direct replacements must match the 600 V rating, 25 A current capacity, and TO-220-2 or TO-220AB package dimensions. Verify gate trigger parameters and holding current limits to ensure compatibility with existing drive circuits.
