H20R120 / H20R1202 / H20R1203 — 1200V 20A IGBT, TO-247 Package
The H20R120 series (including H20R1202 and H20R1203) are 1200V 20A N-channel IGBTs in TO-247 package from Infineon, optimized for induction heating, resonant converters, and high-frequency inverter applications. The “R” designation indicates a reverse-conducting (RC) IGBT with an integrated anti-parallel diode — eliminating the need for an external freewheeling diode in bridge topologies. Each pack contains 5 pieces.

Why Choose H20R120 Series?
- 1200V rating — safe margin for 3-phase 380V/480V and single-phase 220V inverter DC bus
- Integrated anti-parallel diode — RC-IGBT eliminates external freewheeling diode, simplifies circuit
- Optimized for induction heating — low switching losses at 20–100kHz resonant frequencies
- TO-247 package — excellent thermal performance with heatsink mounting
- 5-pack value — enough for full H-bridge or 3-phase inverter stage
Typical Applications
- Induction heating — IH cooker, induction forge, and induction brazing equipment
- Resonant inverters — LLC, SRC, and series resonant converter topologies
- UPS inverter stage — high-voltage battery inverter switching
- Welding machines — IGBT-based inverter welding power supply
- Solar inverters — 1200V-class grid-tie inverter switching stage
FAQ
Q: What is the difference between H20R120, H20R1202, and H20R1203?
A: All are 1200V/20A RC-IGBTs. H20R1202 has faster switching than H20R120; H20R1203 is the fastest of the three with lowest switching losses — best for high-frequency (>50kHz) resonant applications.
Q: Does this IGBT need an external freewheeling diode?
A: No. The RC-IGBT has an integrated anti-parallel diode, making it a complete switch for bridge topologies without external diodes.
Q: What gate drive voltage is recommended?
A: +15V / -8V to -15V for optimal switching performance. Use a dedicated IGBT gate driver IC (e.g., 1EDC20I12AH, IR2110).
