Product details

Overview

IDWD100E65E7XKSA1 from Infineon Technologies is a 650 V, 100 A soft-recovery silicon power diode with emitter-controlled structure, designed for high-reliability freewheeling and anti-parallel roles in hard-switched IGBT modules and inverters. It delivers low and temperature-stable forward voltage (VF = 1.55–2.1 V), very soft reverse recovery (trr = 76.2–163 ns), and low peak reverse recovery current (Irrm = 21.2–44.9 A) at up to 175 °C junction temperature.

For engineers reviewing the IDWD100E65E7XKSA1 datasheet, IDWD100E65E7XKSA1 pinout, IDWD100E65E7XKSA1 application, or IDWD100E65E7XKSA1 equivalent, key selection criteria include softness (low Erec, low di/dt sensitivity), cosmic-ray ruggedness, humidity robustness, and JEDEC-qualified industrial reliability - critical for UPS, microinverter, and aircon PFC stages.

Technical Context

This emitter-controlled diode uses a tailored carrier lifetime profile to achieve soft, fast, and highly temperature-stable reverse recovery - minimizing voltage overshoot and EMI in high-di/dt switching environments. Its internal emitter inductance (LE = 13 nH) and low Rth(j-c) = 0.47 K/W support high-current, high-frequency operation with reduced thermal stress.

The device operates across –40 °C to +175 °C junction temperature, qualified per JEDEC47/20/22 for industrial applications. Its Pb-free lead plating and RoHS compliance meet global environmental requirements without compromising surge robustness (IFSM = 380 A, tp = 10 ms) or long-term reliability under cosmic radiation exposure.

Key Specifications

Parameter	Value and Actual Design Meaning
VRRM	650 V - Withstands repetitive reverse voltage up to 650 V, enabling use in 400 V AC input systems with margin.
IF (rated)	100 A - Continuous forward current rating at Tc = 100 °C, suitable for high-power PFC and inverter legs.
VF @ 100 A / 175 °C	1.55 V - Low, stable forward drop ensures minimal conduction loss and thermal runaway resistance at max operating temperature.

Use Scenario: Boost diode in active PFC stage of inverter-driven residential air conditioners, cycling at 65–100 kHz with 380–420 V DC output.

IC Role / Device Role / Timing Role: Main conduction path during boost switch off-time; must sustain 100 A peak current with minimal conduction loss.

Use Value: 1.55 V VF at 175 °C maintains PFC efficiency >96% even at full-load cabinet temperatures, reducing heatsink size by ~25%.

Use Scenario: Snubber diode in IGBT-based inverter welding power supplies, absorbing inductive kickback during rapid current interruption (di/dt > 1000 A/µs).

IC Role / Device Role / Timing Role: Clamp diode in RC-snubber network, requiring ultra-low trr and minimal Irrm to limit voltage spike amplitude.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-reliability soft-recovery diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IDW20G65C7XKSA1	650 V / 20 A; lower current rating, smaller TO-247-2 package, higher VF (1.75 V typ @ 25 °C)	Suitable for auxiliary or control-stage freewheeling, not main inverter legs	Select when space-constrained designs require same softness but lower current handling and thermal mass.
IDWD120E65E7XKSA1	650 V / 120 A; identical softness and thermal specs, 20 A higher IF rating, same package	Drop-in upgrade for higher-power UPS or welder designs needing extra current headroom	Choose for new designs targeting >110 A continuous conduction or extended lifetime at 100 A with margin.

Compared with IDWD100E65E7XKSA1, IDW20G65C7XKSA1 trades current capacity for footprint reduction while preserving soft recovery, whereas IDWD120E65E7XKSA1 extends current capability without altering thermal or dynamic behavior - enabling scalable platform design across power tiers.

FAQ

What is the maximum recommended case temperature for continuous operation?

The datasheet specifies IF = 100 A at Tc = 100 °C as the rated continuous forward current. Operation above 100 °C case temperature requires derating per the thermal curves in Figure 2; maximum allowable junction temperature remains 175 °C, and Rth(j-c) = 0.47 K/W defines the thermal ceiling for heatsink design.

Is IDWD100E65E7XKSA1 pin-compatible with standard TO-247-2 diodes?

Yes - it uses the PG-TO247-2-STD-NA8.8 outline, matching mechanical dimensions and mounting hole placement of industry-standard TO-247-2 packages. Pin 1 (cathode) and Pin 2 (anode) align with conventional TO-247 diode pinout, enabling direct PCB footprint reuse.

Does this diode require a gate resistor or external control signal?

No - IDWD100E65E7XKSA1 is an uncontrolled, two-terminal power diode. It conducts forward current when anode voltage exceeds cathode voltage by >VF and blocks reverse voltage up to VRRM. No gate drive, biasing, or control circuitry is needed or supported.

How does its cosmic ray ruggedness impact field reliability?

Infineon subjects this diode to accelerated neutron irradiation testing per JEDEC JESD85, confirming immunity to single-event burnout (SEB) up to fluence levels exceeding typical high-altitude or industrial neutron environments. This eliminates latent failure modes in mission-critical UPS and solar installations.
