Q2016LH3

Triacs Overview

The Q2016LH3 is a Littelfuse Alternistor triac rated for 200V off-state voltage and 16A RMS current. It utilizes a TO-220-3 isolated tab package, providing electrical isolation between the leads and the mounting surface. Key electrical parameters include a holding current of 35mA maximum, an on-state voltage of 1.6V, and a gate trigger current range of 20-20-20mA. The device operates within a junction temperature range of -40°C to 125°C.

Triacs Feature Summary

Snubberless operation capability eliminates the need for external RC networks
Electrically isolated TO-220 package removes requirement for separate insulators
Glass-passivated junctions ensure long-term parameter stability

Triacs Applications

AC switching applications requiring noise immunity
Phase control circuits for lighting controls
Temperature modulation control systems

Triacs Procurement Notes

Verify component authenticity through authorized Littelfuse distributors or certified partners. Confirm RoHS compliance status via official documentation prior to integration. Ensure storage conditions align with manufacturer guidelines to maintain junction integrity. Validate package marking against datasheet specifications to prevent counterfeit substitution during assembly processes.

Triacs Selection Notes

Select this component for AC phase control designs where snubberless functionality reduces bill-of-materials complexity. The isolated tab configuration simplifies thermal management by allowing direct heatsink attachment without additional insulation layers. Verify that the 200V blocking voltage meets circuit peak reverse voltage requirements and that the 16A RMS rating accommodates load current peaks.

Triacs Part Context

This device belongs to the QxxxxLTx series of Quadrac devices developed by Littelfuse. These components integrate bidirectional AC switching capabilities with internal gate triggering mechanisms. The series targets applications demanding high noise immunity and simplified circuit topology compared to discrete triac-diac combinations.
