Key Features
- Sensitive gate design with only 0.2 mA DC gate trigger current, enabling direct triggering from low-power microcontrollers or optocouplers without driver stage
- 600 V off-state voltage and 5 A RMS current capacity suitable for AC mains switching and phase control in household and industrial equipment
- TO-220AB package with anode case connection provides excellent thermal dissipation and easy heatsink mounting for continuous power operation
Applications
The TS820-600T is used in AC power control applications such as light dimmers, motor speed controllers, and temperature regulation circuits where phase-angle control from the mains is required. Its sensitive gate allows direct interface from optocoupler outputs, making it ideal for isolated switching in home appliances, HVAC systems, and industrial relay-replacement designs. The 600 V rating gives adequate margin for 120 V and 230 V AC mains applications with standard surge headroom.

Frequently Asked Questions
What makes the TS820-600T suitable for triggering directly from an optocoupler or microcontroller output?
The TS820-600T requires only 0.2 mA DC gate trigger current and 0.8 V gate trigger voltage, far below the output drive capability of most optocouplers and open-collector GPIO pins. This sensitive gate design eliminates the need for a discrete gate driver stage, reducing component count and PCB area in isolated AC switching designs.
What is the blocking voltage rating of the TS820-600T, and how much safety margin does it give on 230 V AC mains?
The TS820-600T is rated at 600 V off-state voltage. On a 230 V AC mains supply the peak voltage is approximately 325 V, so the 600 V rating provides nearly 1.85x margin above the peak, comfortably accommodating typical line transients and surges without exceeding the thyristor's repetitive peak voltage limit.
How does the TO-220AB package help with thermal management in continuous-load SCR applications?
The TO-220AB package features a metal mounting tab connected to the anode, allowing direct attachment to an external heatsink with no isolation washer in non-isolated designs. For a 5 A continuous load this package can achieve junction-to-ambient thermal resistance below 5 °C/W when properly heatsinked, keeping junction temperature within the rated 125 °C limit.
At what holding current does the TS820-600T latch off once gate drive is removed?
The TS820-600T has a maximum holding current of 5 mA, meaning the SCR will turn off naturally once anode current falls below 5 mA after gate drive is removed. This is important in AC phase control circuits to ensure clean commutation at zero crossing, particularly in resistive loads like heating elements operating from a 50 Hz or 60 Hz supply.
