T835H, T850H
High temperature 8 A Snubberless™ Triacs
Datasheet - production data
Features
Medium current Triac
150 °C max. Tj turn-off commutation
Low thermal resistance with clip bonding
Very high 3 quadrant commutation capability
Packages are RoHS (2002/95/EC) compliant
UL certified (ref. file E81734)
Applications
Especially designed to operate in high power
density or universal motor applications such as
vacuum cleaner and washing machine drum
motor, these 8 A Triacs provide a very high
switching capability up to 150 °C junction
temperatures.
The heatsink can be reduced, compared to
traditional Triac, according to the high
performance at given junction temperatures.
Description
Available in through-hole or surface mount
packages, these Triacs series are suitable for
general purpose mains power ac switching.
By using an internal ceramic pad, they provide
voltage insulation (rated at 2500 VRMS).
