BTB08-600BWRG

## **BTA08, BTB08, T810, T835** 

## Snubberless™, logic level and standard 8 A Triacs 

Datasheet - production data 

## **Features** 

- On-state rms current, IT(RMS) 8 A 

- Repetitive peak off-state voltage, VDRM / VRRM 600 V to 800 V 

- Triggering gate current, IGT (Q1) 5 to 50 mA 

## **Description** 

Available either in through-hole or surface-mount packages, the BTA08, BTB08, T810, T835 is suitable for general purpose AC switching. It can be used as an ON/OFF function in applications such as static relays, heating regulation, induction motor starting circuits or for phase control operation in light dimmers and motor speed controllers, etc. 

The Snubberless versions (BTABTB08_xxxxW and T8 series) are specially recommended for use on inductive loads, thanks to their high commutation performances. 

Logic level versions are designed to interface directly with low power drivers such as microcontroller. 

By using an internal ceramic pad, the BTA series provides voltage insulated tab (rated at 2500 VRMS) complying with UL standards (file ref.: E81734).
