T2035H, T2050H
20 A high temperature Snubberless™ Triacs
Datasheet - production data
Description
Available in through-hole or surface mount
packages, these Triacs series are suitable for
general purpose mains power ac switching.
These 20 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.
By using an internal ceramic pad, they provide
voltage insulation (rated at 2500 V
RMS
).
