What are the key features of TYN625RG?
- 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
What is TYN625RG used for?
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.
