FGA25N120ANTD N-Channel IGBT — TO-247, 1200V, 25A, High-Voltage Switching (2-Pack)
The FGA25N120ANTD is a high-voltage N-channel IGBT in a TO-247 package, rated at 1200V collector-emitter voltage and 25A continuous collector current. Designed for high-voltage power conversion applications, it combines low saturation voltage with fast switching characteristics, making it suitable for induction heaters, solar inverters, UPS systems, and industrial motor drives operating from 400V AC mains or higher-voltage DC buses.

Why Choose FGA25N120ANTD?
- 1200V rating — essential for 400V AC three-phase mains applications (peak voltage ~565V + margin)
- Low VCE(sat) 2.0V — low conduction loss at 25A for efficient power conversion
- TO-247 package — large tab for heatsink mounting, handles high power dissipation
- Voltage-controlled gate — driven by standard IGBT gate drivers (IR2110, HCPL-314J, 1EDC20I12AH)
- 2-pack value — one pair for half-bridge or push-pull topology testing

Frequently Asked Questions
Q: What gate driver should I use with FGA25N120ANTD?
A: Use an isolated gate driver for 1200V applications — never use a non-isolated driver with 1200V IGBTs due to safety and noise isolation requirements. Recommended: HCPL-314J (Broadcom, isolated, 2.5A), 1EDC20I12AH (Infineon, isolated), or ACNW3190 (Broadcom). Drive with +15V / −15V gate voltage for full enhancement and fast turn-off. Use a 10–22Ω gate resistor.
Q: What heatsink is required for FGA25N120ANTD at full load?
A: At 25A and VCE(sat)=2.0V, conduction loss is ~50W per device. Add switching losses for your frequency. For a 3-phase inverter at 10kHz, total losses per device may reach 80–100W. Use a heatsink with thermal resistance ≤0.3°C/W with thermal paste and forced air cooling for full-load operation. Always calculate Tj = Ta + (Pd × Rth(j-c) + Pd × Rth(c-h)).
Q: Can FGA25N120ANTD replace GT50J325 or IRG4PC50W in an existing inverter?
A: These are all 600–1200V IGBTs in TO-247. Verify VCES, IC, VCE(sat), switching times, and gate charge before substituting. FGA25N120ANTD (1200V/25A) is generally compatible with other 1200V/25A TO-247 IGBTs, but always confirm switching energy (Eon/Eoff) matches your frequency requirements.
