What this part is and where it fits
The AVS10CB is an internally triggered triac from STMicroelectronics, rated for 600 V off-state voltage and 8 A RMS on-state current, housed in a TO-220-3 through-hole package. It is a single-configuration device designed for AC power control in applications like appliance motor speed controls, light dimmers, and small heater regulators where a simple, self-triggering switch is needed. The internally triggered gate means no external gate drive circuit is required — the device turns on when the applied voltage exceeds its breakover threshold — which simplifies the BOM but limits phase-angle control compared to sensitive-gate triacs.
Lifecycle and sourcing reality
The AVS10CB is listed as Active and ROHS3 compliant. No end-of-life notice is on record, so it remains suitable for new designs and production builds. Sourcing is through independent distribution — availability and current pricing are confirmed at quote time against an RFQ.
