Overview
The Littelfuse S2015LTP is a Silicon Controlled Rectifier (SCR) from the Teccor Sxx15x series, designed for high-current switching applications. It features a rated repetitive off-state voltage (VDRM) of 600 V and an RMS on-state current (It RMS) of 15 A. The device operates within a temperature range of -40°C to +125°C and utilizes a TO-220-2 through-hole package. Key electrical parameters include a forward voltage drop (Vf) of 1.6 V, a gate trigger voltage (Vgt) of 1.5 V, and a gate trigger current (Igt) of 30 mA. The maximum holding current (Ih) is 40 mA, with a non-repetitive peak on-state current capability of 225 A.
Feature Summary
- High current handling capability with 15 A RMS rating in a compact TO-220-2 package
- Robust thermal performance supporting operation up to 125°C junction temperature
- Low forward voltage drop for improved efficiency in power control circuits
Applications
- Industrial motor speed control systems
- AC power regulation and lighting dimmers
- Solid-state relay implementations
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and terminal configuration. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Cross-reference the part number with Littelfuse documentation to validate availability and lead times for production requirements.
Selection Notes
Select this component when a 600 V blocking voltage and 15 A continuous current are required in a standard through-hole form factor. Ensure the gate drive circuit can supply at least 30 mA at 1.5 V to guarantee reliable triggering. Verify that the thermal management design accommodates the power dissipation associated with the 1.6 V forward voltage drop under load conditions.
Part Context
The S2015LTP belongs to the Littelfuse Teccor Sxx15x family of silicon controlled rectifiers. This series is engineered for general-purpose power control applications requiring reliable switching in industrial and commercial environments. The device complements other thyristors in the portfolio by offering a balance of current capacity and voltage rating in a widely used TO-220-2 package.
Replacement Considerations
Consult Littelfuse official substitution guides for compatible SCRs with matching 600 V / 15 A ratings. Verify pinout compatibility and thermal resistance values before replacing existing components in established designs.
