Product details
Overview
IDWD75E65E7XKSA1 from Infineon Technologies is a 650 V, 75 A soft-recovery silicon power diode with emitter-controlled structure, designed for high-reliability rectification in high-frequency switching converters. It delivers low and temperature-stable forward voltage (VF = 1.55–2.1 V), very soft reverse recovery (trr = 97–157 ns), and low peak reverse recovery current (Irrm = 21.3–37.7 A) at 1000 A/µs di/dt, enabling reduced EMI and snubber stress in UPS and inverter applications.
For engineers reviewing the IDWD75E65E7XKSA1 datasheet, IDWD75E65E7XKSA1 pinout, IDWD75E65E7XKSA1 application, or IDWD75E65E7XKSA1 equivalent, key selection criteria include junction temperature capability (Tvjmax = 175 °C), cosmic ray ruggedness, humidity robustness, JEDEC-qualified industrial reliability, and TO-247-2 package thermal resistance (Rth(j-c) = 0.58 K/W).
Technical Context
This emitter-controlled diode uses a proprietary silicon structure to decouple carrier lifetime control from doping profile, achieving simultaneous low VF and soft, fast recovery without external lifetime-killing agents. Its internal emitter inductance (LE = 13 nH) and optimized charge distribution suppress oscillatory turn-off behavior under high di/dt conditions.
The device operates across -40 °C to +175 °C junction temperature range and is qualified per JEDEC47/20/22 for industrial environments. Its 650 V VRRM rating supports use in 400 V AC input systems with margin, while its 300 A IFSM enables robust surge handling in welding and UPS hold-up circuits.

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 |
|---|---|---|---|
| IDW30G65C5XKSA1 | 30 A rated, lower VF (1.45 V @ 175 °C), same TO-247-2 package, but lower IFSM (150 A) | Suitable for lower-power PFC or auxiliary supplies; not rated for 75 A continuous or 300 A surge | Select when system current is ≤30 A and thermal budget allows smaller die size |
| STTH75W06CW | 75 A rated, 600 V VRRM, higher VF (1.85 V @ 175 °C), trr = 120 ns, no cosmic ray qualification | Lacks humidity/cosmic robustness; not JEDEC-qualified for industrial UPS or welding | Acceptable for cost-sensitive residential UPS where reliability margins are relaxed |
Compared with IDW30G65C5XKSA1 and STTH75W06CW, IDWD75E65E7XKSA1 uniquely combines 75 A continuous rating, 650 V margin, soft recovery, and JEDEC industrial qualification-making it the only option for high-reliability 300 A surge-capable inverter rectification.

FAQ
Is IDWD75E65E7XKSA1 pin-compatible with standard TO-247-2 diodes?
Yes-IDWD75E65E7XKSA1 uses the PG-TO247-2-STD-NA8.8 outline, matching mechanical footprint and mounting hole positions of industry-standard TO-247-2 packages. Pin 1 (cathode) and Pin 2 (anode) align with JEDEC MO-247, and the metal tab is cathode-connected, enabling drop-in replacement in existing layouts without PCB redesign.
What is the maximum recommended case temperature for continuous operation?
The datasheet specifies IF = 75 A at Tc = 100 °C, with thermal resistance Rth(j-c) = 0.58 K/W. To maintain Tvj ≤ 175 °C, maximum allowable case temperature is 100 °C under full-rated current. For extended lifetime, Infineon recommends limiting Tc to ≤90 °C when operating continuously at 75 A.
Does IDWD75E65E7XKSA1 require a negative gate drive or external snubber circuitry?
No-it is a two-terminal diode with no gate terminal. Its soft recovery characteristic inherently limits voltage overshoot and oscillation, eliminating the need for external RC snubbers in most 20–100 kHz inverter designs. However, layout inductance should remain <30 nH to preserve specified trr and Irrm performance.
How does cosmic ray ruggedness impact field reliability in ground-level applications?
Cosmic ray ruggedness ensures immunity to single-event burnout (SEB) caused by atmospheric neutrons-even at sea level. This significantly reduces infant mortality and latent failure modes in long-lifetime industrial equipment such as UPS and welding machines, where field returns due to unexplained catastrophic failure are unacceptable.
