Product details
Overview
IDWD100E120D7XKSA1 from Infineon is a 1200 V, 100 A ultrafast soft-recovery emitter-controlled diode in PG-TO247-2-STD package, designed for high-efficiency power conversion in industrial and home appliance inverters. It delivers VF = 2.3–3.0 V (100 A, 25–175°C), trr = 155–210 ns, Qrr = 1.75–4.65 µC, and operates up to Tvj = 175°C.
For engineers reviewing the IDWD100E120D7XKSA1 datasheet, IDWD100E120D7XKSA1 pinout, IDWD100E120D7XKSA1 application, or IDWD100E120D7XKSA1 equivalent, key selection criteria include reverse recovery charge minimization in hard-switched PFC stages, thermal robustness under cyclic load in heat pump compressors, and soft recovery behavior to reduce EMI in EV-charging DC-link circuits.
Technical Context
This diode employs Infineon's Emitter Controlled 7 (EC7) technology, enabling precise control of carrier lifetime without platinum diffusion-yielding lower Qrr and softer recovery than standard fast recovery diodes. Its 1200 V VRRM rating and 175°C max junction temperature support operation in high-voltage DC-link applications with elevated ambient conditions.
The device features low internal emitter inductance (LE = 13 nH, measured 5 mm from case) and optimized layout for reduced switching oscillation. Its Rth(j-c) = 0.29–0.38 K/W enables efficient heatsink coupling in compact industrial inverters where thermal management is constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1200 V - Withstands repetitive reverse voltage in 1200 V DC-link systems without breakdown. |
| IF (Tc = 91°C) | 100 A - Continuous forward current rating at practical heatsink temperature, defining usable conduction capacity. |
| VF (100 A, 175°C) | 2.3 V - Low forward drop at max operating temperature reduces conduction losses in high-duty-cycle inverters. |
| trr (100 A, 25°C) | 205 ns - Ultrafast recovery time limits switching loss during turn-off in 10–20 kHz PFC and inverter stages. |
| Qrr (100 A, 25°C) | 2.45 µC - Low reverse recovery charge minimizes energy dissipation and voltage overshoot in IGBT co-packaged modules. |
| Tvjmax | 175°C - Enables reliable operation in thermally demanding environments such as enclosed heat pump cabinets or EV-charger enclosures. |
| Rth(j-c) | 0.29–0.38 K/W - High thermal conductivity from junction to case supports stable power derating with standard TO-247 mounting. |
Pinout & Package
Package: PG-TO247-2-STD (standard 2-pin TO-247 variant with isolated tab). The backside metal surface serves as cathode terminal; mechanical mounting via M3 screw (0.6 Nm max torque).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Main cathode connection; electrically tied to backside metal tab for low-inductance return path in high-di/dt applications. |
| Backside (tab) | Cathode | Primary cathode terminal and thermal interface; must be electrically isolated from heatsink unless system design requires common-cathode configuration. |
| Pin 2 | Anode | Single anode input; routed to DC-link positive or IGBT collector node in half-bridge configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Emitter Controlled 7 (EC7) technology | Enables precise carrier lifetime tuning for optimal trade-off between VF, Qrr, and softness-no Pt diffusion required. |
| Soft recovery characteristics | Low di/dt during reverse recovery (Irrm ≤ 36 A, dirr/dt ≤ 220 A/µs) suppresses voltage ringing and EMI in high-frequency converters. |
| Humidity robust design | Qualified per JEDEC moisture sensitivity level (MSL) requirements for reflow and long-term field reliability in humid home appliance environments. |
| Pb-free lead plating | RoHS-compliant termination meets global environmental compliance without sacrificing solderability or intermetallic stability. |
Applications
| String Inverter | EV-Charging Station |
|---|---|
Use Scenario: DC-link freewheeling diode in 1000 V+ string inverters with SiC or high-speed IGBTs. IC Role / Device Role / Timing Role: Freewheeling diode in boost PFC and inverter legs, handling 100 A continuous current with <210 ns recovery. Use Value: Low Qrr (2.45 µC) reduces switching loss by ~35% vs. standard FRDs, improving system efficiency above 98.5%. |
Use Scenario: Output rectification and DC-link clamping in liquid-cooled 22 kW AC/DC charging modules. IC Role / Device Role / Timing Role: Reverse-blocking diode in active front-end (AFE) or auxiliary supply, operating at 175°C junction temperature. Use Value: 175°C Tvjmax and soft recovery enable stable operation under transient overload without thermal runaway or EMI excursions. |
| Heat Pump Compressor Drive | Industrial Motor Drive |
Use Scenario: Regenerative braking and DC-link stabilization in variable-speed compressor inverters for HVAC systems.

FAQ
Is IDWD100E120D7XKSA1 pin-compatible with standard TO-247-2 diodes?
Yes-IDWD100E120D7XKSA1 uses the PG-TO247-2-STD mechanical outline with identical mounting hole spacing, screw size (M3), and tab dimensions as industry-standard TO-247-2 packages. Pin 1 (cathode) and Pin 2 (anode) follow conventional labeling, enabling direct mechanical replacement in existing PCB footprints.
What is the maximum recommended case temperature for continuous operation?
The datasheet specifies IF = 100 A at Tc = 91°C, meaning sustained operation at case temperatures up to 91°C is validated. For derated operation, the device supports 146 A at Tc = 25°C and maintains safe junction temperature (≤175°C) when Rth(j-c) ≤ 0.38 K/W and heatsink thermal resistance is properly managed.
How does its soft recovery compare to standard fast recovery diodes?
IDWD100E120D7XKSA1 exhibits peak reverse recovery current (Irrm) of 23 A at 25°C and 36 A at 175°C-significantly lower than typical FRDs (>50 A)-and dirr/dt peaks at 220 A/µs versus >500 A/µs in non-soft diodes. This results in smoother current zero-crossing and reduced voltage overshoot across stray inductance.
Can it replace IKP100N120CH7 in a dual-package module?
No-IKP100N120CH7 is an IGBT, not a diode. However, IDWD100E120D7XKSA1 is the companion diode specified in Infineon's application notes for use with IKP100N120CH7 in half-bridge configurations, sharing matching voltage rating, current capability, and thermal profile for balanced performance.
