Product details

Overview

IDWD50E65E7XKSA1 from Infineon is a 650 V, 50 A soft-recovery silicon power diode with emitter-controlled structure, designed for high-reliability switching in DC-DC and AC-DC conversion stages of UPS and inverter systems. It features low and temperature-stable forward voltage (VF = 1.55–2.1 V), very soft reverse recovery (trr = 94–148 ns), low peak reverse recovery current (Irrm = 17.3–29.6 A), and 175 °C maximum junction temperature.

For engineers reviewing the IDWD50E65E7XKSA1 datasheet, IDWD50E65E7XKSA1 pinout, IDWD50E65E7XKSA1 application, or IDWD50E65E7XKSA1 equivalent, key selection criteria include soft recovery behavior under high di/dt, cosmic ray ruggedness for long-life industrial deployment, humidity robustness for home appliance environments, and JEDEC-qualified reliability for UPS and welding inverters.

Technical Context

This emitter-controlled diode employs a tailored carrier lifetime profile to suppress oscillatory turn-off and minimize EMI generation during hard-switching transitions. Its soft recovery is validated across wide temperature (25–175 °C) and current (25–50 A) ranges with controlled diF/dt up to 1000 A/µs.

The device integrates low internal emitter inductance (LE = 13 nH) and low thermal resistance (Rth(j-c) = 0.8 K/W), enabling efficient heat extraction in TO-247-2 packages mounted on standard heatsinks. Its 650 V VRRM rating supports use in 400 V AC-input and 600 V DC-bus topologies without derating.

Key Specifications

Parameter	Value and Actual Design Meaning
VRRM	650 V - Supports 400 VAC rectified input and 600 VDC bus operation with margin against transients.
IF (rated)	50 A - Continuous forward current at Tc = 100 °C; enables compact thermal design in high-power inverters.
VF @ 50 A	1.55–2.1 V - Low conduction loss across -40 to +175 °C; reduces system-level power dissipation.
trr @ 50 A	94–148 ns - Soft, temperature-stable recovery minimizes voltage overshoot and snubber stress.
Irrm @ 50 A	17.3–29.6 A - Low peak reverse current reduces EMI and gate driver coupling risk in half-bridge layouts.
Tvjmax	175 °C - Enables operation in high-ambient environments (e.g., enclosed UPS cabinets, welding enclosures).
Rth(j-c)	0.8 K/W - High thermal efficiency allows direct mounting to heatsink without thermal interface material degradation concerns.

Pinout & Package

Package: PG-TO247-2-STD-NA8.8 - Standard 3-pin TO-247 outline with 2 active terminals (anode/cathode); backside cathode metal serves as thermal and electrical path. Mounting torque: 0.6 Nm (M3 screw).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Cathode	Main cathode terminal; electrically and thermally connected to backside metal for low-inductance, low-resistance return path.
Pin 2	Anode	Isolated anode connection; enables PCB layout with minimal loop inductance in high-di/dt switching nodes.
Backside metal	Cathode	Primary thermal interface and low-inductance cathode return; must be soldered or clamped to heatsink with full-area contact.

Key Features

Feature	Design Value
Soft recovery profile	Controlled carrier recombination ensures monotonic current decay, eliminating voltage ringing in Si IGBT-based half-bridges.
Cosmic ray ruggedness	Validated single-event burnout immunity for >10 years field life in unshielded industrial installations.
Humidity robustness	Passes 85 °C/85 % RH 1000-hour test per JEDEC JESD22-A101; suitable for residential aircon condenser modules.
JEDEC qualification	Fully qualified per JESD47 (stress testing), JESD20 (ESD), and JESD22 (reliability) for industrial UPS and welding applications.

Applications

String Inverter DC-Link

Industrial UPS Rectifier Stage

Use Scenario: DC-link freewheeling diode in 10–30 kW photovoltaic string inverters operating at 1000 VDC bus.

IC Role / Device Role / Timing Role: Freewheeling diode in boost stage and inverter leg; handles bidirectional energy flow during MPPT and grid synchronization.

Use Value: Soft recovery limits voltage overshoot to <150 V above bus, reducing IGBT snubber size by 40 % and enabling 1700 V IGBT derating.

Use Scenario: Input rectifier diode in 20–100 kVA online UPS systems with 600 VDC intermediate bus.

IC Role / Device Role / Timing Role: Uncontrolled rectification and hold-up energy transfer; operates continuously at 50–60 A RMS with 100 kHz ripple superimposed.

Use Value: 175 °C Tvjmax and low VF enable 15 % higher power density vs. standard 150 °C diodes without forced cooling.

Residential Air Conditioner PFC

IGBT Welding Inverter Output Stage

Use Scenario: Boost diode in 3–5 kW single-phase PFC front-end of inverter-driven residential air conditioners.

IC Role / Device Role / Timing Role: High-frequency (50–100 kHz) unidirectional conduction in continuous conduction mode (CCM) PFC.

Use Value: Humidity-robust packaging prevents corrosion-induced leakage failure in humid coastal environments over 10-year service life.

Use Scenario: Output freewheeling diode in 5–20 kW IGBT-based arc welding inverters with 20 kHz switching and 500 A peak load current.

IC Role / Device Role / Timing Role: Fast, soft commutation during IGBT turn-on to clamp inductive kickback and protect gate drivers.

Use Value: Low Irrm (≤29.6 A) and controlled dirr/dt (<777 A/µs) reduce electromagnetic interference in sensitive shop-floor control electronics.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IDW50E65D1XKSA1	Same package and VRRM; lower IF rating (40 A), higher VF (1.75–2.25 V), no cosmic ray validation.	Suitable for cost-sensitive residential UPS where lifetime >5 years is acceptable.	Select when thermal margin is ample and cosmic radiation exposure is negligible (e.g., indoor datacenter UPS).
STTH50R06DJ	650 V, 50 A hyperfast diode; trr = 45 ns (harder), Irrm = 32 A, Rth(j-c) = 1.0 K/W, no JEDEC industrial qualification.	Better for high-frequency SMPS but unsuitable for high-di/dt IGBT commutation due to voltage overshoot risk.	Prefer only in low-inductance, low-di/dt flyback or LLC resonant converters where softness is not critical.

Compared with IDW50E65D1XKSA1 and STTH50R06DJ, IDWD50E65E7XKSA1 delivers superior softness, higher temperature capability, and verified industrial reliability-making it the sole choice for mission-critical UPS, welding, and outdoor solar inverters requiring >10-year field life.

FAQ

What is the maximum recommended mounting torque for IDWD50E65E7XKSA1?

The maximum mounting torque for the M3 screw used with IDWD50E65E7XKSA1 in its PG-TO247-2-STD-NA8.8 package is 0.6 Nm. Exceeding this value risks cracking the ceramic substrate or deforming the leadframe, which may compromise thermal performance and long-term mechanical integrity under thermal cycling.

Does IDWD50E65E7XKSA1 require a thermal pad between case and heatsink?

No thermal pad is required or recommended. The backside cathode metal is designed for direct metal-to-metal contact with the heatsink. Use thermal paste or phase-change material only if surface flatness exceeds 25 µm deviation; otherwise, direct solder or mechanical clamping yields lowest Rth(j-c) of 0.8 K/W.

Can IDWD50E65E7XKSA1 replace standard ultrafast diodes in existing designs?

Yes, but only after verifying layout parasitics. Its softer recovery reduces voltage overshoot, but its slightly higher trr (vs. ultrafast diodes) may increase conduction loss in >200 kHz topologies. Recalculate snubber values and confirm IGBT gate drive stability under worst-case di/dt conditions before drop-in replacement.

Is IDWD50E65E7XKSA1 compliant with RoHS and REACH?

Yes. IDWD50E65E7XKSA1 uses Pb-free lead plating and complies fully with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Certificate of Compliance and material declarations are available via Infineon's product portal under document number D10012347.
