Product details

Overview

IHY20N120R3XKSA1 from Infineon is a reverse-conducting IGBT (RC-IGBT) with monolithic body diode, rated for 1200 V V_CE, 20 A I_C continuous at T_C = 100°C, and 1.48 V V_CE(sat) at 25°C - optimized for high-efficiency inductive cooking inverters operating up to 175°C junction temperature.

For engineers reviewing the IHY20N120R3XKSA1 datasheet, IHY20N120R3XKSA1 pinout, IHY20N120R3XKSA1 application, or IHY20N120R3XKSA1 equivalent, key selection criteria include its trench-stop technology-enabled positive V_CE(sat) temperature coefficient, integrated low-V_F body diode for soft commutation, and TO-247HC package with enhanced creepage/air gap for high-voltage isolation.

Technical Context

This RC-IGBT integrates a co-packaged, low-forward-voltage body diode on a single die, eliminating external anti-parallel diode requirements in half-bridge inverter legs. Its trench-stop structure delivers tight parameter distribution and stable switching behavior across -40°C to +175°C.

It features a 15.7 S transconductance, 211 nC total gate charge, and 0.48 K/W junction-to-case thermal resistance - enabling robust parallel operation and efficient thermal management in compact induction heating modules.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CE max	1200 V - supports DC bus voltages up to 850 V in 3-phase rectified systems with margin for voltage spikes.
I_C cont @ T_C=100°C	20 A - defines continuous output current capability under real heatsink conditions in induction cooktop power stages.
V_CE(sat) @ 25°C	1.48 V - directly determines conduction loss (P_cond ≈ I_C × V_CE(sat)) at room temperature.
E_off @ 175°C	1.65 mJ - quantifies turn-off energy loss under worst-case thermal stress, critical for thermal design of 20–50 kHz inverters.
R_th(j-c)	0.48 K/W - enables calculation of junction temperature rise above heatsink (ΔT = P_diss × 0.48).
Q_g	211 nC - determines required gate driver peak current (I_pk = Q_g/t_rise) for <100 ns switching transitions.
T_j max	+175°C - allows sustained operation in sealed, thermally constrained induction coil enclosures without derating.

Pinout & Package

Supplied in PG-TO247HC-3 package - a reinforced variant of TO-247 with increased creepage (>4.5 mm) and clearance distances versus standard TO-247, qualified per JEDEC J-STD-020/JESD-022.

Pin/Terminal	Circuit Role	Design Meaning
Collector (C)	Main high-side current path	Connected to DC+ bus; carries full load current and must be routed with low-inductance layout to minimize voltage overshoot.
Gate (G)	Control input	Requires low-impedance drive (≤15 Ω series R) and local 100 nF decoupling to ensure clean 15 V switching edge and suppress oscillation.
Emitter (E)	Power return and reference node	Serves as common source for IGBT and body diode; must be star-connected to minimize ground bounce in half-bridge configurations.

Key Features

Feature	Design Value
Monolithic body diode	Low V_F (1.55 V @ 25°C) and soft recovery enable zero-voltage switching (ZVS) in resonant inverter topologies without external diode.
TrenchStop® technology	Positive V_CE(sat) temperature coefficient ensures inherent current sharing in paralleled devices and stable operation at elevated temperatures.
TO-247HC package	Enhanced creepage (>4.5 mm) meets IEC 60335-1 reinforced insulation requirements for household induction appliances.
JEDEC-qualified reliability	Qualified to J-STD-020 (moisture sensitivity) and JESD-022 (HTSL, TST), supporting industrial-grade production life cycles.

Applications

Induction Cooktop Inverter

Industrial Induction Heater

Use Scenario: Half-bridge resonant inverter driving 20–50 kHz LC tank for pan detection and heating control in domestic cooktops.

IC Role / Device Role / Timing Role: High-side switch in asymmetrical half-bridge; body diode conducts freewheeling current during dead-time.

Use Value: Monolithic diode eliminates discrete diode placement and layout parasitics, reducing EMI and improving ZVS margin by 15% over discrete solutions.

Use Scenario: Medium-power (3–6 kW) solid-state induction heater for metal hardening or brazing in factory environments.

IC Role / Device Role / Timing Role: Primary switching device in phase-shifted full-bridge topology; handles repetitive 100% duty-cycle bursts at 10–30 kHz.

Use Value: 175°C T_j rating and 0.48 K/W R_th(j-c) allow direct mounting to aluminum heatsinks without thermal derating in unventilated enclosures.

Induction-Based Water Heater

Wireless Power Transfer Transmitter

Use Scenario: Compact 2–3 kW tankless water heater using series-resonant topology with digital frequency control.

IC Role / Device Role / Timing Role: Low-loss switching element in high-Q resonant circuit; body diode provides controlled reverse recovery during zero-current switching transitions.

Use Value: Soft-recovery body diode reduces di/dt-induced voltage ringing, lowering EMI filter component count by 30% compared to fast-recovery diode hybrids.

Use Scenario: 1–2 kW resonant transmitter pad for EV wireless charging (SAE J2954 compliant) operating at 85 kHz.

IC Role / Device Role / Timing Role: Inverter switch in Class-E or DAB topology; operates with precise gate timing to maintain constant-frequency resonance under variable coupling.

Use Value: Tight V_CE(sat) distribution (±0.1 V) ensures consistent power delivery across multi-unit transmitter arrays without individual calibration.

Equivalent & Alternatives

The following parts are listed as comparable options for similar reverse-conducting IGBT applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXYS IXGN20N120B3	Higher V_CE(sat) (1.75 V @ 25°C), larger Q_g (240 nC), same TO-247 package but no monolithic diode - requires external ultrafast diode.	Limited to non-resonant topologies where diode recovery is less critical; higher conduction loss reduces efficiency in 20–50 kHz range.	Select only if existing PCB layout uses discrete diode footprint and thermal budget permits +0.27 V higher saturation drop.
STMicroelectronics STGW20H120DF2	Lower V_CE(sat) (1.40 V), lower E_off (1.35 mJ @ 175°C), but body diode V_F is higher (1.75 V) and recovery is less soft.	Better for hard-switched converters; less suitable for ZVS inductive cooking due to higher diode reverse recovery charge (Q_rr = 1200 nC vs. IHY20N120R3's ~850 nC).	Prefer when minimizing turn-off loss dominates over diode softness - e.g., in fixed-frequency PWM-based heaters without resonant tuning.

Compared with IXGN20N120B3 and STGW20H120DF2, IHY20N120R3XKSA1 uniquely balances low V_CE(sat), soft diode recovery, and thermal ruggedness - making it the optimal choice for resonant inductive cooking where ZVS margin, EMI, and thermal density are co-constrained.

FAQ

What is the maximum recommended gate resistor value for reliable switching?

The datasheet specifies 15 Ω as the reference gate resistor for switching characterization. Using >22 Ω increases turn-off delay and energy loss significantly - especially above 100°C - and risks incomplete turn-off during short-circuit events. For 20–50 kHz operation, 10–15 Ω is optimal to balance EMI and loss.

Can IHY20N120R3XKSA1 replace a standard IGBT + external diode pair?

Yes - its monolithic body diode replaces discrete ultrafast diodes in half-bridge legs. However, layout must account for shared emitter node: the internal diode shares the same emitter terminal, so Kelvin emitter sensing requires separate sense traces from the main emitter pad.

Is the TO-247HC package pin-compatible with standard TO-247?

Yes - mechanical footprint and pin assignment (C-G-E) match standard TO-247-3. The HC variant adds thicker molding compound and extended creepage paths but retains identical mounting hole spacing and screw torque specification (0.6 Nm for M3).

What is the safe operating area (SOA) limitation at 175°C junction temperature?

At T_j = 175°C, the DC SOA is limited to 60 A at V_CE ≤ 1200 V, with pulse width dependence shown in Figure 2. For 100 µs pulses, maximum current drops to ~45 A; for 1 ms, it falls to ~12 A - confirming strict adherence to the published FBSOA curves is required for reliability.
