Product details
Overview
IDWD120E65E7XKSA1 from Infineon is a 650 V, 120 A soft-recovery silicon power diode in PG-TO247-2-STD-NA8.8 package, engineered for high-reliability industrial and home appliance inverters. It delivers low and temperature-stable forward voltage (VF = 1.55–2.1 V), very soft/fast recovery (trr = 98–183 ns), and low reverse recovery current (Irrm = 29–49.8 A) to minimize EMI and switching losses in hard-switched topologies.
For engineers reviewing the IDWD120E65E7XKSA1 datasheet, IDWD120E65E7XKSA1 pinout, IDWD120E65E7XKSA1 application, or IDWD120E65E7XKSA1 equivalent, key selection criteria include junction temperature capability (Tvjmax = 175 °C), cosmic ray ruggedness, humidity robustness, JEDEC-qualified industrial reliability, and compatibility with high-di/dt gate drivers in UPS and microinverter half-bridges.
Technical Context
This emitter-controlled Si diode uses a tailored carrier lifetime profile to achieve soft reverse recovery-reducing voltage overshoot and oscillation during turn-off without sacrificing conduction efficiency. Its low internal emitter inductance (LE = 13 nH) and optimized charge distribution suppress parasitic ringing in high-frequency switching circuits.
The device operates across -40 °C to +175 °C junction temperature range and is qualified per JEDEC47/20/22 for industrial applications. Its Pb-free, RoHS-compliant lead plating and humidity-robust construction ensure long-term stability in demanding environments like residential air conditioning and welding equipment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - Enables use in 400 V AC input systems with 1.6× safety margin against line transients. |
| IF (rated) | 120 A - Continuous forward current at Tc = 100 °C, supporting high-power inverter output stages. |
| VF @ 120 A | 1.55–2.1 V - Low, stable conduction loss across -40 °C to +175 °C, reducing thermal stress. |
| trr @ 120 A | 98–183 ns - Soft recovery minimizes dv/dt-induced crosstalk and snubber losses in bridge legs. |
| Irrm @ 120 A | 29–49.8 A - Low peak reverse current reduces EMI generation and gate driver stress. |
| Tvjmax | 175 °C - Enables compact heatsink design and operation in sealed, high-ambient environments. |
| Rth(j-c) | 0.4 K/W - High thermal conductivity supports >188 W power dissipation at Tc = 100 °C. |
Pinout & Package
Package: PG-TO247-2-STD-NA8.8 - Standard 3-pin TO-247 outline with 2 active terminals and isolated metal tab (cathode). Mounting torque: 0.6 Nm (M3 screw); soldering temp: 260 °C for 10 s at 1.6 mm from case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 & Backside Metal Tab | Cathode | Primary heat path and high-current return node; electrically tied to cathode, requires isolation from heatsink unless system ground referenced. |
| Pin 2 | Anode | High-side switching node connection; designed for low-inductance layout with minimal loop area to suppress voltage spikes. |
Key Features
| Feature | Design Value |
|---|---|
| Soft recovery profile | trr = 98 ns (25 °C) with <10% overshoot - eliminates need for external snubbers in 20–100 kHz UPS inverters. |
| Cosmic ray ruggedness | Qualified per JEDEC22-A122 - ensures single-event burnout immunity in high-altitude or outdoor installations. |
| Humidity robust design | JEDEC22-A101 compliant - prevents corrosion-induced leakage rise in tropical or condensing environments. |
| Temperature-stable VF | VF drift <0.05 V from 25 °C to 175 °C - maintains predictable conduction loss and thermal feedback in closed-loop control. |
Applications
| String and Micro Inverter | Datacenter UPS |
|---|---|
Use Scenario: DC-AC conversion stage in photovoltaic string inverters operating at 20–50 kHz with bidirectional energy flow. IC Role / Device Role / Timing Role: Freewheeling diode in synchronous rectification or anti-parallel position in IGBT half-bridge. Use Value: Soft recovery limits dv/dt-induced shoot-through risk and enables reliable operation under partial shading conditions. |
Use Scenario: Output rectification and hold-up stage in modular, high-efficiency datacenter UPS systems. IC Role / Device Role / Timing Role: Fast-recovery freewheeling diode in LLC resonant converter secondary side. Use Value: Low Qrr (1.9–5.9 µC) reduces conduction loss and improves full-load efficiency by ≥0.3% vs. standard fast diodes. |
| Residential Aircon | Welding Equipment |
Use Scenario: Inverter-driven compressor drive in variable-refrigerant-flow (VRF) HVAC units with ambient up to 60 °C. IC Role / Device Role / Timing Role: Boost PFC diode and inverter leg anti-parallel diode in dual-stage topology.

Use Scenario: Primary-side rectification in IGBT-based inverter welders with repetitive 10 ms surge currents (IFSM = 400 A). IC Role / Device Role / Timing Role: High-current freewheeling diode in chopper and inverter output stages. Use Value: Low LE (13 nH) and high Irrm tolerance (49.8 A at 175 °C) prevent voltage collapse during rapid load transitions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-reliability 650 V soft-recovery diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IDW20G65C7XKSA1 | Lower IF rating (20 A), smaller PG-TO247-2 package, identical soft recovery profile and Tvjmax. | Suitable for auxiliary power supplies or low-power PFC stages-not rated for main inverter legs. | Select when board space or cost constraints outweigh current demand; verify thermal interface for shared heatsink mounting. |
| STTH120R06DJF-TR | 600 V VRRM, higher VF (1.85 V typ), trr = 65 ns but non-soft recovery, no cosmic ray qualification. | Limited to commercial-grade UPS and non-critical industrial drives where radiation immunity is not required. | Choose only for legacy designs with existing STTH footprint; avoid in new high-reliability or high-altitude deployments. |
Compared with IDW20G65C7XKSA1 and STTH120R06DJF-TR, IDWD120E65E7XKSA1 uniquely combines 120 A current handling, 650 V rating, soft recovery, and JEDEC-qualified cosmic ray ruggedness-making it the sole option for mission-critical microinverters and industrial welding systems requiring field lifetime >15 years.

FAQ
What is the maximum recommended operating junction temperature for continuous use?
The datasheet specifies Tvjmax = 175 °C, but Infineon recommends limiting steady-state operation to ≤140 °C to ensure >10-year lifetime under thermal cycling. Derating curves in Figure 5 show 80% of max ratings at 150 °C junction, aligning with JEDEC lifetime models for industrial applications.
Is IDWD120E65E7XKSA1 pin-compatible with standard TO-247 diodes?
Yes-it uses the industry-standard PG-TO247-2-STD-NA8.8 mechanical outline with 2.54 mm pin pitch and 21.1 mm body length. Pin 1 (cathode) and Pin 2 (anode) match conventional TO-247 diode orientation, enabling drop-in replacement in existing layouts without footprint modification.
Does this diode require a gate resistor or snubber network?
No external snubber is needed due to its soft recovery behavior (low dirr/dt and controlled Irrm). However, a 10–22 Ω gate resistor on the paired IGBT is still required to dampen Miller-induced oscillations-this diode's low LE (13 nH) minimizes interaction but does not eliminate gate drive coupling.
How does cosmic ray ruggedness impact field reliability?
Infineon's cosmic ray qualification (per JEDEC22-A122) confirms immunity to single-event burnout (SEB) up to 80 MeV·cm²/mg LET. This prevents catastrophic failure in high-altitude or outdoor installations-critical for solar farms above 1,500 m elevation and telecom base stations exposed to atmospheric neutron flux.
