HGTG30N60A4D N-Channel IGBT — TO-247, 600V, 30A, Ultra-Fast Switching
The HGTG30N60A4D is an ultra-fast N-channel insulated gate bipolar transistor (IGBT) in a TO-247 package, rated at 600V collector-emitter voltage and 30A continuous collector current. Designed for high-frequency switching applications, it combines the low saturation voltage of a bipolar transistor with the voltage-controlled gate of a MOSFET. It is widely used in induction heaters, resonant inverters, UPS systems, motor drives, and welding inverters where 600V high-current switching at frequencies above 20kHz is required.

- Voltage-controlled gate — driven by standard IGBT gate driver ICs (IR2110, HCPL-314J)
- Onsemi / Fairchild heritage — industry-standard part with comprehensive datasheet and application notes
Compatible With / Common Use Cases
- Induction heater: ZVS (zero-voltage switching) induction heater circuit, 12–48V supply, 20–50kHz
- Resonant inverter: LLC or series resonant converter for high-efficiency power conversion
- UPS inverter: Single-phase or three-phase UPS output stage, 50/60Hz to 20kHz PWM

Frequently Asked Questions
Q: What gate driver IC should I use with HGTG30N60A4D?
A: Use a dedicated IGBT gate driver with ±15V gate drive (VGE=+15V for on, −15V for fast turn-off). Recommended: IR2110 (half-bridge bootstrap), HCPL-314J (isolated), 1EDC20I12AH (Infineon). Use a 10–22Ω gate resistor to control switching speed and limit EMI. Never drive the gate directly from a microcontroller GPIO.
Q: What heatsink do I need for HGTG30N60A4D at 30A?
A: At 30A and VCE(sat)=2.35V, conduction loss is ~70W. Add switching losses for your frequency. A heatsink with thermal resistance ≤0.5°C/W with thermal paste is required for full-load operation. For most applications, derate to 15–20A with a medium heatsink (1–2°C/W) and forced air cooling.
Q: Can HGTG30N60A4D replace GT30J122 or GT30F124 in an induction heater?
A: These are all 600V ultra-fast IGBTs in TO-247 with similar ratings. Verify VCE(sat), switching times, and gate charge before substituting. HGTG30N60A4D is generally compatible with ZVS induction heater circuits designed for GT30J122 or similar ultra-fast 600V IGBTs.
