QK016RH6TP

Triacs Overview

The Littelfuse QK016RH6TP is a bidirectional triac rated for 1 kV repetitive off-state voltage and 16 A RMS on-state current. It features a gate trigger current of 80 mA with a maximum holding current of 70 mA. The device exhibits an on-state voltage of 1.6 V and an off-state leakage current of 100 uA at rated voltage. Operating within a temperature range of -40 C to +125 C, it utilizes a TO-220-3 package for surface or panel mounting.

Triacs Feature Summary

• Provides bidirectional AC switching capability for phase control applications
• Designed for high-voltage industrial environments with robust thermal stability
• Features low gate sensitivity for efficient triggering circuitry

Triacs Applications

• Industrial motor speed control systems
• High-power temperature regulation circuits
• AC power switching modules

Triacs Procurement Notes

Verify the specific suffix configuration against official Littelfuse documentation to ensure compatibility with required voltage and current ratings. Confirm that the TO-220-3 package variant matches the intended thermal management strategy. Cross-reference the datasheet specifications for gate trigger parameters to validate interface requirements before finalizing procurement orders.

Triacs Selection Notes

Select this component when high blocking voltage and significant current handling are required in a standard through-hole format. Ensure the application circuit can accommodate the specified gate trigger characteristics. Evaluate thermal dissipation needs relative to the 16 A rating and operating temperature limits to maintain reliable performance under continuous load conditions.

Triacs Part Context

This device belongs to the Qxx16xHx series of thyristors manufactured by Littelfuse. The series is engineered for general-purpose AC switching tasks requiring reliable performance in demanding electrical environments. It serves as a solid-state alternative to mechanical relays in high-power control scenarios.

Triacs Replacement Considerations

QK016NH6TP offers identical electrical ratings but utilizes an SMTO-263-2 surface mount package instead of the TO-220-3 form factor.
