Product details

Sensitive-gate TRIAC for 230 VAC phase control

The STMicroelectronics T410-600B-TR is a logic-level sensitive-gate TRIAC rated for 600 V off-state voltage and 4 A RMS on-state current, housed in a surface-mount DPAK (TO-252-3) package. The 10 mA maximum gate trigger current lets a low-voltage logic output drive it directly through a series resistor.

With a maximum gate trigger current of 10 mA and a maximum trigger voltage of 1.3 V, this part qualifies as a sensitive-gate triac. The 15 mA maximum holding current means the load must draw at least that much to keep the triac latched once triggered.

The ROHS3 compliance covers the current exemption list — no lead in solder or finishes beyond the allowed thresholds.

Frequently asked questions

Is T410-600B-TR obsolete or active?

The T410-600B-TR is Active in production with no end-of-life notice. It is a current-production part.

Is T410-600B-TR RoHS compliant?

Yes, the T410-600B-TR is ROHS3 Compliant.

What are the substitute parts for T410-600B-TR?

The T405-600B is a same-voltage (600 V), same-current (4 A) logic-level triac in a DPAK package but supplied in tube rather than tape-and-reel. The T405-700B-TR is a 700 V, 4 A variant in the same tape-and-reel format. Neither is a direct pin-for-pin replacement without verifying the package footprint and tape orientation.
