Overview
The Littelfuse SK016RTP is a standard phase control silicon controlled rectifier (SCR) designed for high-voltage, high-current switching applications. It features a 1000V repetitive peak off-state voltage and a 16A average on-state current rating. The device utilizes a TO-220AB-R through-hole package, providing robust mechanical stability and thermal dissipation capabilities. Key electrical characteristics include an off-state leakage current of 20 µA at VDRM and a gate trigger voltage below 1.5V, requiring only a few milliamps of gate current for activation. This component serves as a reliable unidirectional switch in power electronics circuits.
Feature Summary
- Provides excellent unidirectional switching functionality specifically engineered for phase control applications.
- Features low gate trigger requirements, activating with potentials below 1.5V and minimal gate current.
- Designed for robust performance in heating elements and motor speed control systems.
Applications
- Phase control applications for electric heating systems
- Motor speed control circuits
- General purpose AC power switching
Procurement Notes
Verify the specific package variant upon ordering, as documentation references both TO-220-2 and TO-220-3 configurations for this part number. Confirm that the required voltage and current ratings align with the 1000V and 16A specifications. Ensure compatibility with through-hole mounting processes and verify gate trigger characteristics against circuit design requirements to guarantee proper operation.
Selection Notes
Select the SK016RTP when phase control precision and high voltage isolation are required in single-phase AC applications. Its low gate sensitivity makes it suitable for simple triggering circuits. Consider the thermal management capabilities of the TO-220 package for sustained load conditions. Evaluate the 20 µA leakage current specification for standby power constraints in sensitive electronic designs.
Part Context
The SK016RTP belongs to the Sx16x series of standard phase control SCRs from Littelfuse. This series is characterized by its reliability in industrial and consumer power control environments. The component is part of the broader Teccor brand portfolio, focusing on thyristor solutions for efficient energy transfer and control in resistive and inductive loads.
Replacement Considerations
Cross-reference with other 1000V, 16A phase control SCRs in TO-220 packages. Verify pinout compatibility and thermal resistance values before substitution. Ensure equivalent gate trigger voltage and holding current specifications to maintain circuit stability and performance in existing designs.
