Product details

Overview

IDWD140E120D7XKSA1 from Infineon is a 1200 V, 140 A ultrafast soft-recovery emitter-controlled diode in PG-TO247-2-STD package, optimized for high-efficiency power conversion in string inverters and EV charging systems. It delivers VF = 2.3–3.0 V (140 A, 25–175 °C), trr = 160–245 ns, Qrr = 3.1–7.55 µC, and Tvjmax = 175 °C with low Erec and robust humidity resistance.

For engineers reviewing the IDWD140E120D7XKSA1 datasheet, IDWD140E120D7XKSA1 pinout, IDWD140E120D7XKSA1 application, or IDWD140E120D7XKSA1 equivalent, key selection criteria include reverse recovery charge at 175 °C, softness factor (low Irrm/diF/dt ratio), thermal resistance Rth(j-c) = 0.21–0.27 K/W, and JEDEC-qualified industrial reliability.

Technical Context

This emitter-controlled diode uses Infineon's Emitter Controlled 7 (EC7) technology to achieve ultrafast recovery with minimal voltage overshoot and oscillation during turn-off. Its soft recovery behavior-evidenced by low dirr/dt (115–260 A/µs) and controlled Irrm (27–50 A)-reduces EMI and stress on co-packaged IGBTs in hard-switched topologies.

The device operates across -40 to +175 °C junction temperature, supports repetitive surge currents up to 420 A (IFRM), and features Pb-free RoHS-compliant plating with humidity-robust packaging validated per JEDEC22-A101/A110. Thermal design leverages low Rth(j-c) and defined mounting torque (0.6 Nm for M3 screw).

Key Specifications

Parameter	Value and Actual Design Meaning
VRRM	1200 V - Enables use in 1000 V DC-link systems with 20% safety margin against transients.
IF (Tc = 91 °C)	140 A - Continuous forward current rating at realistic heatsink temperature for industrial thermal management.
VF (140 A, 175 °C)	2.3 V - Low conduction loss enabling >98.5% efficiency in 15–30 kW string inverters.
trr (140 A, 175 °C)	245 ns - Ultrafast recovery minimizes switching losses and enables >20 kHz operation with IGBTs.
Qrr (140 A, 175 °C)	7.55 µC - Critical for calculating turn-on losses of paired IGBTs and snubber sizing.
Rth(j-c)	0.21–0.27 K/W - Enables direct thermal interface to heatsink without thermal pad derating penalties.
Tvjmax	175 °C - Supports extended lifetime under sustained overload in heat pump PFC stages.

Pinout & Package

Package: PG-TO247-2-STD (standard 2-pin TO-247 variant with isolated case). Backside metallization serves as cathode terminal; anode is accessible via lead pin only.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Cathode	Primary cathode connection; electrically tied to backside metal for low-inductance layout in high-di/dt applications.
Backside	Cathode	Thermally and electrically active cathode surface-must be mounted to heatsink with conductive thermal interface material.
Pin 2	Anode	Single-point anode termination; requires short, low-inductance PCB trace to minimize voltage spikes during recovery.

Key Features

Feature	Design Value
Emitter Controlled 7 (EC7) Technology	Enables precise carrier lifetime control for consistent softness and reduced Qrr variation over temperature.
Soft Recovery Characteristics	Low Irrm/diF/dt ratio (<0.05) suppresses ringing and reduces snubber losses in IGBT half-bridges.
JEDEC Industrial Qualification	Validated per JEDEC47/20/22 for 15-year field life in outdoor-rated solar inverters and EVSE enclosures.
Humidity Robust Design	Passes 1000-hr 85 °C/85% RH bias test-ensures long-term reliability in tropical climate heat pump installations.
Pb-Free & RoHS Compliant	Meets EU Directive 2011/65/EU and IPC-J-STD-020 moisture sensitivity level (MSL) 1 rating.

Applications

String Inverter

EV Charging Station

Use Scenario: Frequent hard-switching in 3-phase NPC or T-type inverter legs handling 10–25 kW DC input.

IC Role / Device Role / Timing Role: Anti-parallel freewheeling diode for 1200 V Si IGBTs, managing reactive energy during PWM commutation.

Use Value: 245 ns trr at 175 °C ensures <1.2% increase in total switching loss vs. room temperature, maintaining system efficiency across ambient range.

Use Scenario: Bidirectional AC/DC conversion in liquid-cooled 22 kW AC chargers with active PFC and isolated DC/DC stage.

IC Role / Device Role / Timing Role: Output rectifier in phase-shifted full-bridge DC/DC converter operating at 100–200 kHz.

Use Value: 7.55 µC Qrr at 175 °C enables accurate prediction of IGBT turn-on loss and eliminates need for dynamic gate drive tuning.

Heat Pump Inverter

Industrial Motor Drive

Use Scenario: High-voltage PFC front-end in variable-speed air-source heat pumps operating continuously at -25 to +45 °C ambient.

IC Role / Device Role / Timing Role: Boost diode in continuous conduction mode (CCM) PFC stage with 1000 V DC bus.

Use Value: 2.3 V VF at 175 °C reduces conduction loss by 18% versus standard fast diodes, improving seasonal COP by 0.15 points.

Use Scenario: Regenerative braking path in 400–690 V three-phase drives for HVAC compressors and conveyor systems.

IC Role / Device Role / Timing Role: Reverse-energy clamping diode in DC link, absorbing motor back-EMF during rapid deceleration.

Use Value: 462 A non-repetitive IFSM rating withstands 10-ms regen surges without degradation, supporting IP55-rated drive enclosures.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH160S12	Higher VF (2.9 V @ 140 A, 175 °C); trr = 270 ns; no JEDEC industrial qualification.	Limited to commercial-grade UPS and lighting ballasts-not rated for outdoor solar or EVSE environments.	Select when cost sensitivity outweighs thermal performance and long-term reliability requirements.
IXYS MDD150-12N1	Lower Qrr (5.2 µC @ 140 A, 175 °C) but higher VF (2.65 V); Rth(j-c) = 0.32 K/W; TO-247-3 package with isolated tab.	Requires separate cathode isolation; less optimal for direct heatsink mounting in compact inverters.	Prefer where lower Qrr dominates design priority and layout allows extra isolation clearance.

Compared with STTH160S12 and MDD150-12N1, IDWD140E120D7XKSA1 offers superior thermal resistance, JEDEC-validated lifetime, and tighter Qrr/VF trade-off-making it the preferred choice for mission-critical renewable energy and EV infrastructure designs.

FAQ

What is the maximum recommended mounting torque for IDWD140E120D7XKSA1?

The datasheet specifies a maximum mounting torque of 0.6 Nm for M3 screws. Exceeding this value risks mechanical damage to the ceramic insulator or solder joint integrity, potentially compromising thermal resistance and long-term reliability under thermal cycling.

Does IDWD140E120D7XKSA1 require a thermal pad between the backside cathode and heatsink?

No thermal pad is required-the device is designed for direct metal-to-metal contact using thermally conductive grease or phase-change material. The backside cathode metallization is fully compatible with standard heatsink interface materials and meets IPC-7351B land pattern requirements.

Can IDWD140E120D7XKSA1 replace standard ultrafast diodes like UF3007 in existing designs?

Direct replacement is not recommended due to higher IF rating (140 A vs. 3 A), different package (PG-TO247-2 vs. DO-15), and significantly higher VRRM (1200 V vs. 1000 V). Layout, thermal, and gate-drive interactions must be re-validated for any substitution.

Is the internal emitter inductance (LE = 13 nH) measured from the case or from the pins?

LE = 13 nH is measured 5 mm from the case edge along the leads, per Table 1 in the datasheet. This value reflects parasitic inductance in the internal bond wire and lead frame-critical for modeling voltage overshoot during di/dt events above 1000 A/µs.
