QK016NH4RP

Triacs Overview

The Littelfuse QK016NH4RP is a bidirectional triac designed for AC switching applications. It features an RMS on-state current (It RMS) of 16 A and a rated repetitive off-state voltage (VDRM) of 1 kV. The device operates within a temperature range of -40°C to +125°C and utilizes an SMTO-263-2 surface-mount package. Key electrical parameters include a maximum holding current (Ih) of 50 mA, a gate trigger voltage (Vgt) of 2 V, and a gate trigger current (Igt) of 35 mA. The on-state voltage is specified at 1.6 V, with a leakage current of 5 uA under VDRM conditions.

Triacs Feature Summary

Triacs Procurement Notes

Verify component authenticity through authorized Littelfuse distributors or certified suppliers. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Ensure storage conditions maintain moisture sensitivity level integrity. Validate datasheet revisions against specific production batches to guarantee parameter consistency.

Triacs Selection Notes

Select this component when a 1 kV blocking voltage is required in a compact SMD form factor. Compare gate sensitivity requirements against alternative series if lower trigger currents are necessary. Evaluate thermal dissipation capabilities relative to the expected RMS load current and ambient operating temperatures.
