STMicroelectronics Z01 Series Triac, 1A, 600V, SOT-223

The STMicroelectronics Z01 Series Triac is a versatile 1A, 600V solid-state switch designed for general-purpose AC control in a compact SOT-223 package. Its 3mA gate current sensitivity makes it easy to drive with low-power control circuits, providing reliable switching for a wide range of household and industrial applications.

This triac is engineered for stability and efficiency, with a maximum on-state voltage of 1.6V to minimise power loss during conduction. It is built to withstand high transient currents, featuring a peak non-repetitive surge current rating of 8A. The component is surface-mount ready, facilitating automated assembly for high-volume production.

Ideal Applications

• Perfect for controlling small AC motors in appliances like pumps and fans, including speed control circuits.
• Suitable for switching solenoids and electrovalves in white goods and automated systems.
• An excellent choice for dimming or on/off control of small lamps and lighting circuits.
• Can be used in domestic security devices such as electronic door locks.

With a high operating temperature maximum of 125°C and robust construction, this triac offers dependable performance in demanding environments. Its standard ratings and footprint make it a reliable, drop-in solution for upgrading or designing new AC power control systems.
