Key Features
- Sensitive gate triggers with as little as 0.2 mA DC gate current, enabling low-power control
- 600 V off-state voltage rating suits AC mains-connected switching and phase-control circuits
- TO-220AB package provides excellent thermal dissipation for reliable continuous conduction
Applications
The TS420-600T is designed for AC power control applications such as lamp dimmers, motor speed controllers, and heating regulators where a sensitive gate SCR simplifies drive circuitry. Its 600 V blocking voltage and low gate trigger current of 0.2 mA make it suitable for direct interface with microcontrollers or optocouplers in solid-state relay designs. Industrial equipment and home appliance designers rely on this SCR for robust, cost-effective phase-angle control at mains voltages.

Frequently Asked Questions
What is the maximum off-state voltage and minimum gate trigger current of the TS420-600T?
The TS420-600T is rated for a 600 V off-state voltage, making it suitable for 230 V AC mains applications. Its maximum DC gate trigger current is only 0.2 mA, allowing it to be driven directly from low-power microcontroller outputs or optocouplers without additional amplification stages.
Which package does the TS420-600T use, and how does it benefit thermal management in motor control designs?
The TS420-600T uses a TO-220AB package with an anode case connection, enabling easy heatsink mounting to dissipate heat during continuous conduction in motor speed control circuits. This through-hole package simplifies PCB assembly and provides a low thermal resistance path for managing junction temperatures in demanding industrial environments.
How does the TS420-600T compare to non-sensitive gate SCRs when designing a 230 V lamp dimmer?
Unlike standard SCRs that require gate trigger currents of 5 mA to 20 mA, the TS420-600T needs only 0.2 mA maximum to latch on, reducing driver circuit complexity and power consumption in a 230 V lamp dimmer design. Its 5 mA holding current ensures reliable commutation, and the 600 V rating provides adequate margin over peak mains voltage, making it a preferred choice for cost-sensitive consumer dimmer applications.
