Overview
The Littelfuse SJ4025R1TP is a Silicon Controlled Rectifier (SCR) belonging to the SJxx25xx series, designed for high-temperature industrial applications. It features a rated repetitive off-state voltage (VDRM) of 400 V and an on-state RMS current (It RMS) of 12 A. The device utilizes a gate trigger voltage (Vgt) of 1.5 V for activation. It operates within a temperature range from -40 °C to +150 °C and is housed in a surface-mount TO-263AB-3 package. This component is qualified under the AEC-Q101 standard, ensuring reliability for automotive and demanding electronic environments.
Feature Summary
- High-temperature operation capability up to 150 °C
- Automotive-grade qualification via AEC-Q101 standard
- Surface-mount construction in a compact TO-263AB-3 package
Applications
- Automotive power control circuits
- Industrial motor drive systems
- High-temperature rectification applications
Procurement Notes
Verify the specific suffix 'TP' against official Littelfuse documentation to confirm tape-and-reel packaging requirements. Confirm that the AEC-Q101 qualification status remains valid for the intended automotive application. Ensure the 12 A RMS current rating aligns with the thermal management design of the target system.
Selection Notes
Select this component when a 400 V SCR is required in a surface-mount form factor. The 12 A current rating suits moderate power loads compared to higher-current alternatives. Verify that the 1.5 V gate trigger voltage matches the available drive circuit capabilities. Consider the TO-263AB-3 package dimensions for PCB layout constraints.
Part Context
This part belongs to the SJxx25xx series of thyristors manufactured by Littelfuse. These devices are engineered for robust performance in power control scenarios. The series offers various voltage and current ratings to accommodate different circuit requirements while maintaining consistent package and qualification standards.
Replacement Considerations
Consult Littelfuse official substitution guides for verified equivalents. Generic thyristor replacements may not match the AEC-Q101 automotive qualification or the specific thermal characteristics of the original component.
