T1235H, T1250H
High temperature 12 A Snubberless™ Triacs
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 12 A Triacs provide a very high
switching capability up to junction temperatures of
150 °C.
The heatsink can be reduced, compared to
traditional Triacs, according to the high
performance at given junction temperatures.
Description
Available in through-hole or surface mount
packages, the T1235H and T1250H Triac series
are suitable for general purpose mains power ac
switching.
By using an internal ceramic pad, the T12xxH-6I
provides voltage insulation (rated at 2500 V rms).
