The TPDV1225RG: ROHS3 compliance is confirmed, so the part meets the latest European environmental restrictions without requiring an exemption review.
Load-switching capability and surge handling
Rated for 25 A RMS on-state current with a 1.2 kV off-state voltage, this triac switches AC loads like heaters, motors, and lighting directly from the mains without a separate relay. The non-repetitive surge rating of 230 A at 50 Hz and 250 A at 60 Hz covers the inrush from incandescent lamps or capacitor-start motors — the device survives the first few cycles without failure.
Snubberless alternistor — inductive-load advantage
With a maximum gate trigger current of 150 mA and gate trigger voltage of 1.5 V, the device is directly drivable from a microcontroller I/O through a simple resistor, provided the MCU can source that current. The 50 mA maximum holding current keeps the triac latched on down to a low load current, reducing the risk of premature turn-off in lightly loaded circuits.
Package and thermal path
Housed in a TOP-3 through-hole package (also known as TOP3), the device is designed for mounting on a heatsink — the metal tab is the collector terminal and provides the primary thermal path to the ambient. Supplied in tube packaging, the TPDV1225RG is suited for manual assembly or selective wave-solder processes where tape-and-reel is not required.
