Product details
Overview
IDWD20E65E7XKSA1 from Infineon is a 650 V, 20 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 V @ Tvj = 175 °C), very soft fast recovery (trr = 74 ns @ 25 °C), and low reverse recovery current (Irrm = 12.4 A), enabling reduced EMI and switching losses in UPS and aircon PFC stages.
For engineers reviewing the IDWD20E65E7XKSA1 datasheet, IDWD20E65E7XKSA1 pinout, IDWD20E65E7XKSA1 application, or IDWD20E65E7XKSA1 equivalent, key selection criteria include its cosmic ray ruggedness, humidity robust design, JEDEC-qualified industrial reliability, and 175 °C maximum junction temperature - critical for high-temperature, long-lifetime power conversion systems.
Technical Context
This emitter-controlled Si diode uses optimized carrier lifetime control to achieve soft reverse recovery with minimal oscillation and low di/dt-induced voltage overshoot. Its internal emitter inductance is tightly controlled at 13 nH (measured 5 mm from case), supporting stable commutation in hard-switched topologies.
The device operates across -40 °C to 175 °C junction temperature range and is qualified per JEDEC47/20/22 for industrial applications. Its thermal resistance Rth(j-c) = 1.55 K/W enables efficient heat transfer to heatsinks in compact UPS and welding inverter designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - supports 400 V AC input rectification with 1.6× safety margin in offline UPS and micro-inverters |
| IF (rated) | 20 A continuous - defines nominal conduction capability at Tc = 25 °C; derates to 25 A at Tc = 100 °C |
| VF @ 20 A / 175 °C | 1.55 V - enables low conduction loss and reduced thermal stress in high-temp residential aircon compressors |
| trr @ 20 A / 25 °C | 74 ns - ensures soft, low-overshoot turn-off in 50–100 kHz PFC and DC-link freewheeling |
| Irrm @ 20 A / 25 °C | 12.4 A - minimizes peak reverse current stress on IGBTs/MOSFETs during commutation |
| Rth(j-c) | 1.55 K/W - allows direct mounting to heatsink with predictable thermal drop in industrial welding inverters |
| Tvjmax | 175 °C - extends lifetime under sustained overload in datacenter UPS battery-charging circuits |
Pinout & Package
Package: PG-TO247-2-STD-NA8.8 - insulated plastic case with isolated collector tab, M3 screw mount, 21.1 mm height, and 13.5 mm lead spacing for high-voltage creepage compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 & Backside | Cathode | Primary high-current output node; electrically connected to metal tab for low-inductance heatsink coupling |
| Pin 2 | Anode | Input terminal for forward conduction; isolated lead enables PCB-level isolation in bridge configurations |
Key Features
| Feature | Design Value |
|---|---|
| Soft recovery profile | trr = 74 ns with <10% current tail - suppresses voltage ringing and reduces snubber losses in high-di/dt PFC stages |
| Temperature-stable VF | VF decreases only 0.1 V from 25 °C to 175 °C - maintains consistent conduction loss across operating range |
| Cosmic ray ruggedness | Qualified per JEDEC22-A122 - prevents single-event burnout in high-altitude or mission-critical industrial UPS |
| Humidity robust design | IEC 60068-2-30 compliant - ensures long-term reliability in tropical residential aircon environments |
| Pb-free & RoHS | Lead plating meets EU RoHS Directive 2011/65/EU - supports eco-compliant manufacturing and end-of-life recycling |

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 |
|---|---|---|---|
| IDW20E65D1XKSA1 | Same VRRM/IF but faster trr (55 ns @ 20 A), higher Irrm (14.2 A), no cosmic ray qualification | Better for ultra-high-frequency PFC (>150 kHz); less suitable for high-altitude or long-lifetime UPS | Select when EMI reduction outweighs cosmic ray immunity requirements |
| STTH20L06S | 600 V VRRM, 20 A IF, VF = 1.75 V @ 175 °C, trr = 85 ns, not JEDEC industrial qualified | Limited to 600 V AC mains; lower thermal margin in 175 °C environments | Cost-sensitive alternative where 650 V margin and 175 °C operation are non-critical |
Compared with IDWD20E65E7XKSA1, IDW20E65D1XKSA1 trades cosmic ray ruggedness for faster recovery, while STTH20L06S sacrifices voltage margin and industrial qualification for lower cost - making IDWD20E65E7XKSA1 optimal for mission-critical, high-temperature, high-reliability UPS and aircon systems.

FAQ
What is the maximum allowable case temperature for continuous operation?
The datasheet specifies IF = 25 A at Tc = 100 °C and IF = 42 A at Tc = 25 °C. For continuous 20 A operation, the maximum recommended case temperature is 100 °C to maintain junction temperature ≤175 °C with Rth(j-c) = 1.55 K/W. Exceeding this requires derating or enhanced cooling.
Does IDWD20E65E7XKSA1 require a gate resistor or external snubber network?
No - as a diode, it has no gate. However, its soft recovery reduces need for RC snubbers; typical designs use only a small 100 pF–1 nF capacitor across anode-cathode if ringing persists above 100 MHz. The 13 nH internal emitter inductance is already optimized for minimal parasitic interaction.
Is the backside cathode electrically isolated from the mounting screw hole?
Yes - the PG-TO247-2-STD-NA8.8 package features an insulated metal tab. The backside cathode is isolated from the screw hole and heatsink interface; mounting torque must not exceed 0.6 Nm to avoid compromising insulation integrity per datasheet specification.
How does humidity robustness impact PCB layout and conformal coating requirements?
The device's humidity robust design eliminates need for additional conformal coating over the diode body. PCB layout should still maintain ≥2.5 mm creepage between anode and cathode traces per IEC 60664-1, but no special encapsulation or underfill is required for 95% RH environments.
