Overview
The Littelfuse S8015L is a Silicon Controlled Rectifier (SCR) designed for high-power AC switching applications. It features a maximum RMS on-state current of 15A and supports repetitive peak off-state voltages of up to 800V. The device utilizes a single-element structure housed in an electrically isolated TO-220AB flange mount package with three pins. Key electrical parameters include a gate trigger current of 30mA and a non-repetitive surge current rating of 150A at 60Hz. The component is RoHS compliant and UL recognized, ensuring suitability for industrial power control systems requiring robust thermal and electrical performance.
Feature Summary
- Electrically isolated TO-220AB flange mount package eliminates the need for external insulators
- Glass-passivated junctions ensure long-term parameter stability and reliability
- High surge current capability for handling transient load conditions
Applications
- Industrial motor speed controls
- Temperature modulation systems
- Lighting control circuits
Procurement Notes
Verify the specific voltage suffix (e.g., L51 for 500V or L55 for 800V) as the base part number S8015L denotes the series rather than a single voltage rating. Confirm RoHS compliance status and UL recognition details directly from the manufacturer's datasheet before finalizing procurement specifications.
Selection Notes
Select the appropriate voltage variant based on the circuit's peak reverse voltage requirements. Ensure the mounting surface area supports the thermal dissipation needs for continuous 15A operation. Verify that the gate drive circuit can supply the required 30mA trigger current under all operating temperature conditions.
Part Context
This component belongs to the Teccor Quadrac family of integrated triacs and diacs manufactured by Littelfuse. These devices combine a bidirectional AC switch with an internal trigger mechanism in a single package. The S8015L specifically represents the high-current SCR variant within this portfolio, distinct from standard Triac models.
Replacement Considerations
Equivalent parts include the Teccor Electronics S8015L51 and S8015L55. Verify pinout compatibility and thermal resistance characteristics when substituting with components from other manufacturers offering similar 15A SCR specifications.
