AN2777
Application note
New high-temperature, high-performance TRIACs for
optimized vacuum cleaner designs
Introduction
A new high-temperature TRIAC family, able to work up to a 150 °C junction temperature in
steady-state, has been introduced. This family helps to reduce the bulk of the required
heatsink. These TRIACs are particularly suitable for hot or limited environments found in
home appliances, such as vacuum cleaners.
One key parameter in the design of TRIACs operating at high temperature is the turn-off
capability. We explain here briefly how to optimize this parameter and present the
performances of a new 12 A, 600 V device.
Test results are also presented to compare these performances to other high-temperature
TRIACs available on the market today. These tests are performed in extremely severe
temperature conditions as can appear in vacuum cleaners.
