Product details

600 V / 6 A Snubberless triac — industrial AC load switching

The STMicroelectronics T630-600W is a Snubberless™ Alternistor triac rated for 600 V off-state and 6 A RMS on-state continuous current, housed in an ISOWATT220AB-3 through-hole package.

Surge current and thermal headroom

Non-repetitive surge current is rated 80 A at 50 Hz and 84 A at 60 Hz, giving the device headroom for inrush from capacitive or motor-start loads.

Gate drive and hold current

Maximum gate trigger current is 30 mA and maximum gate trigger voltage is 1.3 V — compatible with standard MCU GPIOs through a series resistor or a small driver transistor. The 50 mA maximum hold current ensures the triac stays latched once triggered, even with lightly inductive loads that might otherwise drop below the holding threshold.

Obsolete — sourcing and replacement reality

STMicroelectronics lists the T630-600W as obsolete.

Frequently asked questions

Is T630-600W obsolete and what are the alternatives?

Yes, STMicroelectronics has marked the T630-600W as obsolete. No direct replacement order code is listed by ST. A functionally similar Snubberless triac in the ISOWATT220AB-3 package from ST's current portfolio should be cross-referenced for new designs. For existing production, the part can be sourced through independent channels against an RFQ.
