25 A RMS, 1 kV off-state — AC load switching anchor
The STMicroelectronics TPDV1025RG is a single Alternistor-Snubberless triac rated for 25 A RMS on-state current and 1 kV off-state voltage, housed in a TOP-3 through-hole package. The snubberless construction eliminates the external RC snubber typically needed for inductive loads, reducing BOM count and board area in AC switching circuits.
Gate drive and hold current — trigger margin check
Maximum gate trigger current is 150 mA, with a maximum gate trigger voltage of 1.5 V. The maximum hold current is 50 mA. These values define the minimum drive the controller or optocoupler must deliver to reliably latch the triac on and keep it conducting through the zero-cross.
Surge capability and thermal range
Non-repetitive surge current is rated at 230 A for 50 Hz and 250 A for 60 Hz, giving headroom for motor inrush and capacitor charging events.
