Overview
The Littelfuse S8015LTP is a silicon controlled rectifier (SCR) designed for phase control applications. It features an 800 V repetitive peak off-state voltage and a 15 A RMS on-state current rating. The device utilizes a TO-220AB flange mount package with an isolated mounting tab, allowing for common anode or cathode circuit configurations. Key electrical parameters include a maximum DC gate trigger current of 30 mA and a non-repetitive peak on-state current capability of 167 A or 200 A depending on the specific datasheet variant. It operates within a temperature range of -40°C to +125°C.
Feature Summary
- Isolated mounting tab enables flexible circuit integration for common anode or cathode connections.
- Glass-passivated junctions provide robust protection against voltage transients up to 1000 V ratings in the series.
Applications
- DC phase control applications with motor loads
- General purpose power switching circuits
- Industrial AC/DC power conversion systems
Procurement Notes
Verify the exact suffix designation when ordering, as variations such as Q8015L5TP or D8015LTP may exist within the same manufacturer family but differ in component type (Triac vs. Rectifier). Confirm RoHS compliance status and specific datasheet revision numbers to ensure compatibility with existing thermal management designs and regulatory requirements.
Selection Notes
Select this component for high-current DC phase control where isolation between the heatsink and circuit ground is required. Ensure the thermal resistance of the mounting interface supports the 15 A RMS continuous current dissipation. Verify that the gate trigger current requirements of the driving circuit align with the specified 30 mA maximum limit to guarantee reliable turn-on under all operating conditions.
Part Context
This part belongs to the Littelfuse Teccor brand thyristor family, specifically categorized under silicon controlled rectifiers. It shares design characteristics with other high-voltage SCR models intended for industrial power control, distinguishing itself through its specific 800V rating and TO-220AB packaging format suitable for panel or chassis mounting.
Replacement Considerations
Direct substitutes must match the 800V VDRM, 15A IT(RMS), and TO-220AB package dimensions. Cross-reference with other manufacturers' 800V SCRs in similar flange-mount packages, ensuring identical pinout configurations and thermal performance metrics are maintained for seamless integration.
