Overview
The SJ8025LTP is a sensitive gate silicon junction thyristor (SCR) manufactured by IXYS, now part of Littelfuse. It features an ITO-220AB through-hole package with two pins. Key electrical parameters include a maximum repetitive peak off-state voltage of 800V and a maximum on-state current of 25A. The device supports a non-repetitive surge current of up to 300A at 50Hz or 350A at 60Hz. It operates within a junction temperature range of -40°C to 150°C.
Feature Summary
- Sensitive gate triggering mechanism for reliable control
- Robust thermal performance in ITO-220AB package
- High surge current capability for industrial loads
Applications
- Industrial motor control systems
- Power supply regulation circuits
- Lighting dimmer applications
Procurement Notes
Verify the manufacturer designation as Littelfuse due to the acquisition of IXYS. Confirm the specific suffix LTP corresponds to the standard ITO-220AB lead configuration. Ensure compatibility with sensitive gate drive requirements. Check for updated datasheets reflecting Littelfuse branding while maintaining original electrical specifications.
Selection Notes
Select this component for applications requiring high voltage blocking capability and moderate continuous current handling. The sensitive gate feature simplifies driver circuit design compared to standard gates. Consider the thermal resistance of the ITO-220AB package for heat dissipation needs. Evaluate the surge current rating against potential inrush conditions in the target application.
Part Context
This SCR belongs to the broader category of power thyristors used in high-power switching applications. IXYS was a prominent provider of such discrete semiconductors before being acquired by Littelfuse. The product line continues under the Littelfuse brand, maintaining the historical electrical characteristics and packaging standards established during the IXYS era.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other 800V, 25A SCRs in ITO-220AB packages only after verifying gate sensitivity and thermal parameters match the original design requirements.
