Q6006LTH

Triacs Overview

The Littelfuse Q6006LTH is a Quadrac device, which integrates a triac and an internal diac trigger within a single TO-220-2 package. It features a rated repetitive off-state voltage (VDRM) of 600 V and an on-state RMS current (ITRMS) of 6 A. The device exhibits a maximum holding current (Ih) of 50 mA and an on-state voltage (VTM) of 1.6 V. Gate triggering is achieved via breakover voltage (VBO) ranging from 33 V to 43 V with a maximum breakover current (IBO) of 25 uA. It operates within a temperature range of -40°C to +125°C and includes a non-repetitive peak on-state current capacity of up to 80 A.

Triacs Feature Summary
