Key Features
- 600 V off-state blocking voltage with 1000 V/µs critical dv/dt rating for robust noise immunity in industrial AC power control circuits
- 16 A RMS on-state current with low 1.3 V maximum gate trigger voltage enabling direct microcontroller gate drive without additional gate amplifier stages
- TO-220AB package with anode case connection for direct heatsink mounting, supporting thermal dissipation at full 16 A load in compact power modules
Applications
The TYN625RG is used in AC power control applications including light dimmers, motor speed controllers, and heating element regulators operating on 230 V or 120 V mains supply. Its 600 V blocking voltage and 40 mA gate trigger current make it compatible with optocoupler-isolated gate drive circuits in safety-critical appliance and industrial equipment designs. It also appears in soft-start circuits, static switches, and solid-state relays where controlled phase-angle firing at 50 Hz or 60 Hz mains frequency is required.

Frequently Asked Questions
What is the maximum RMS on-state current rating of TYN625RG in a typical heatsink-mounted configuration?
The TYN625RG is rated for 16 A RMS on-state current when the case is maintained at or below 75°C through adequate heatsinking. Without a heatsink in free air at 25°C ambient, the safe current is substantially reduced to approximately 4 A to 6 A depending on duty cycle, so a heatsink with thermal resistance below 3 °C/W is recommended for full 16 A operation in AC power control applications.
How does the 1000 V/µs dv/dt rating of TYN625RG protect against spurious triggering?
The TYN625RG can withstand off-state voltage rises up to 1000 V/µs without spurious turn-on, making it highly resistant to fast voltage transients from inductive load switching, motor back-EMF, and mains-line noise spikes. This dv/dt immunity exceeds the 200 V/µs to 500 V/µs rating of lower-cost SCRs, reducing the need for RC snubber networks and simplifying gate drive design in 230 V mains-powered motor control circuits.
Can the TYN625RG gate be driven directly from a microcontroller GPIO through an optocoupler?
Yes, TYN625RG requires a maximum gate trigger current of 40 mA at 1.3 V maximum gate trigger voltage, which is directly compatible with standard optocoupler output transistors such as MOC3020 or 4N25 driving a 100 Ω to 150 Ω gate resistor from a 5 V supply. This eliminates the need for a dedicated gate amplifier stage, reducing total circuit component count by 3 to 5 parts in a typical zero-cross phase-control firing design.
How does TYN625RG in TO-220AB compare to TYN625 in D2PAK for surface-mount power control boards?
The TYN625RG in TO-220AB is a through-hole package requiring a PCB drill hole and optional bolt-mount heatsink, while a D2PAK variant allows SMT assembly with the heat slug soldered to a PCB copper pad, eliminating the separate heatsink mechanical fastener. For automated SMT production lines with 16 A current requirements, D2PAK offers lower assembly cost, but TO-220AB remains preferred when a chassis-mount aluminum heatsink exceeding 50 cm² is needed to sustain full 16 A continuous current at 85°C ambient.
