Product details
Overview
IDW30E65D1FKSA1 from Infineon Technologies is an emitter-controlled diode (ECD) optimized for high-frequency, high-efficiency industrial power conversion. It delivers 650 V blocking capability, 30 A forward current rating at 100 °C case temperature, 1.35 V forward voltage at 30 A and 25 °C, ultra-fast 66 ns reverse recovery time, and operates up to 175 °C junction temperature - enabling use in PFC boost stages and motor drive freewheeling paths.
For engineers reviewing the IDW30E65D1FKSA1 datasheet, IDW30E65D1FKSA1 pinout, IDW30E65D1FKSA1 application, or IDW30E65D1FKSA1 equivalent, key selection criteria include its low Qrr (0.73 µC), soft recovery (softness factor >1), temperature-stable VF, and TO-247-3 package with isolated pin 1 - critical for high-reliability AC/DC and inverter designs.
Technical Context
This emitter-controlled diode uses a proprietary silicon structure that decouples conduction and switching behavior, enabling simultaneous low VF and ultra-low Qrr without trade-offs typical of standard fast recovery diodes. Its internal emitter inductance is tightly controlled at 13.0 nH, minimizing voltage overshoot during turn-off.
The device exhibits monotonic, temperature-stable trr and Qrr across -40 °C to 175 °C, with reverse recovery charge rising only to 1.83 µC at 175 °C under 1000 A/µs di/dt - confirming robust performance in thermally demanding motor drive and solar inverter applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - supports 400 V AC mains-derived DC bus with 1.6× safety margin in PFC and inverter stages |
| IF (TC = 100 °C) | 30 A - continuous forward current rating usable in compact heatsinked industrial SMPS |
| VF @ 30 A, 25 °C | 1.35 V - reduces conduction loss by ~15% vs. comparable 650 V FREDs, improving system efficiency |
| Qrr @ 25 °C | 0.73 µC - minimizes switching loss and EMI in high-frequency (>100 kHz) PFC circuits |
| trr @ 25 °C | 66 ns - enables stable operation with Si IGBTs and SiC MOSFETs in hard-switched topologies |
| Tvjmax | 175 °C - allows derating headroom for sustained overload in industrial motor drives |
| Softness factor | >1 - ensures non-oscillatory, low-dV/dt reverse recovery, reducing snubber stress and RFI |
Pinout & Package
Package: PG-TO247-3 - insulated mounting base, industry-standard through-hole power package with creepage/clearance compliant to IEC 60664-1 for 650 V systems.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Not connected | Electrically isolated terminal; must remain unconnected to avoid parasitic coupling or thermal path disruption |
| Pin 2 + backside | Cathode | Primary cathode connection; backside metal serves as main current return and thermal interface to heatsink |
| Pin 3 | Anode | Controlled anode terminal; carries full forward current and defines switching node in bridge configurations |
Key Features
| Feature | Design Value |
|---|---|
| Emitter-controlled architecture | Decouples carrier lifetime control from doping profile, enabling independent optimization of VF and Qrr |
| Temperature-stable Qrr | Qrr increases only 2.5× from 25 °C to 175 °C (0.73 → 1.83 µC), ensuring predictable loss in thermal transients |
| Low internal emitter inductance | 13.0 nH - limits voltage spike during di/dt = 1000 A/µs, reducing need for external snubbers |
| Pb-free, RoHS-compliant plating | Meets IPC-J-STD-020 moisture sensitivity level 1 (MSL-1), suitable for lead-free reflow and wave soldering |
Applications
| AC/DC Power Supply PFC Stage | Industrial Motor Drive Inverter |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar emitter-controlled diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH30R06DJF | 600 V VRRM, 30 A IF, 1.75 V VF, 1.2 µC Qrr, standard FRED architecture | Lacks soft recovery and temperature-stable Qrr; higher conduction and switching loss | Acceptable where cost is primary constraint and thermal margin exists; not recommended for >80 kHz PFC |
| IXYS MDD30-65 | 650 V VRRM, 30 A IF, 1.55 V VF, 1.1 µC Qrr, soft recovery but no emitter control | Higher Qrr and VF than IDW30E65D1FKSA1; less stable Qrr vs. temperature | Suitable for lower-frequency (<50 kHz) motor drives; requires larger heatsink due to 0.2 V higher VF |
Compared with STTH30R06DJF and MDD30-65, IDW30E65D1FKSA1 delivers superior system efficiency in high-frequency, thermally constrained applications due to its uniquely low Qrr/VF combination and intrinsic softness - reducing both passive component count and thermal management complexity.

FAQ
What is the maximum allowable case temperature for continuous 30 A operation?
The datasheet specifies 30 A forward current at TC = 100 °C. Operation above this temperature requires linear derating per Figure 2: at 125 °C case, rated current drops to ~22 A. Exceeding 100 °C without derating risks exceeding 175 °C junction limit under worst-case thermal resistance (Rth(j-c) = 1.06 K/W).
Is pin 1 internally connected or truly isolated?
Pin 1 is explicitly defined as "not connected" in the official package pin definition and confirmed in the die layout. It is electrically and thermally isolated from all active regions and must remain unconnected in PCB layout to prevent unintended coupling or mechanical stress on the leadframe.
How does the softness factor >1 impact EMI in PFC designs?
A softness factor >1 indicates non-oscillatory, monotonic current decay during reverse recovery, eliminating high-frequency ringing. This reduces broadband EMI emissions by 10–15 dB in the 30–100 MHz range, allowing smaller Y-capacitors and simplified EMI filter design in Class B conducted emission compliance.
Can IDW30E65D1FKSA1 replace standard 650 V FREDs without circuit modification?
Yes - it is a direct drop-in replacement in TO-247-3 footprint with identical pinout (anode on pin 3, cathode on pin 2 + backside). However, its lower Qrr and softer recovery may reduce snubber losses and gate driver stress, potentially allowing minor optimization of existing snubber components in high-performance designs.
