Product details
Overview
IDFW60C65D1XKSA1 from Infineon Technologies is an Emitter Controlled Diode (ECD) in a fully isolated TO-247 package, designed for high-efficiency 650V industrial power conversion. It delivers dual 30A legs with 1.45V forward voltage at 30A/25°C, 0.76µC reverse recovery charge, and 2500VRMS galvanic isolation - enabling use in high-frequency PFC and inverter stages of air conditioning inverters and general-purpose drives.
For engineers reviewing the IDFW60C65D1XKSA1 datasheet, IDFW60C65D1XKSA1 pinout, IDFW60C65D1XKSA1 application, or IDFW60C65D1XKSA1 equivalent, this device offers verified thermal stability up to 175°C junction temperature, low Qrr under 1000A/µs di/dt conditions, and validated isolation integrity for safety-critical motor drive designs.
Technical Context
This Emitter Controlled Diode integrates two independent 650V/30A diode legs in a single PG-TO247-3-AI package with electrically isolated mounting surface. Its rapid switching behavior is defined by trr ≤112ns (at 1000A/µs, 25°C), Irrm ≤17.6A, and dirr/dt ≤−1360A/µs - all measured under standardized inductive load conditions with IGW50N65H5 switch co-simulation.
The device employs advanced isolation technology delivering 2500VRMS withstand voltage at 50/60Hz for 1 minute, with 100% tested isolation barrier and thermal resistance Rth(j–h) = 1.50K/W (typ). Junction-to-heatsink thermal path is optimized for forced-air or heatsink-cooled industrial SMPS topologies operating across −40°C to +175°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650V - Maximum repetitive reverse blocking voltage per leg; enables direct use in 400VAC input rectification and 600V DC-link applications. |
| IF (per leg) | 30A continuous @ Tvj=25°C - Sustains full-rated current without derating when heatsink temperature remains ≤65°C. |
| VF @ 30A/25°C | 1.45V - Low conduction loss improves system efficiency in high-current PFC and output rectification stages. |
| Qrr | 0.76µC @ diF/dt=1000A/µs - Minimizes switching loss and EMI generation during hard-commutation in IGBT-based inverters. |
| trr | 65ns @ diF/dt=1000A/µs - Enables operation at higher PWM frequencies (>20kHz) without excessive diode tail losses. |
| Tvj max | 175°C - Allows compact thermal design with reduced heatsink mass in space-constrained industrial drives. |
| Visol | 2500VRMS - Meets reinforced insulation requirements for Class I equipment per IEC 61800-5-1 in motor drives. |
Pinout & Package
Package: PG-TO247-3-AI (fully isolated TO-247 variant with insulated mounting base). Mounting torque: 0.6 Nm (M3 screw). Isolation layer must not be mechanically compromised during assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (A1) | Anode of first diode leg | Connects to high-side switching node in dual-leg configurations; electrically isolated from heatsink and Pin 2/3. |
| Pin 2 (C) | Cathode common to both legs | Serves as shared return path; requires low-inductance layout to minimize voltage spikes during simultaneous commutation. |
| Pin 3 (A2) | Anode of second diode leg | Enables symmetrical dual-diode topology for interleaved PFC or half-bridge freewheeling; independent isolation from A1 and C. |
Key Features
| Feature | Design Value |
|---|---|
| Emitter Controlled Technology | Enables precise control of carrier lifetime for optimized trade-off between VF and Qrr - unlike conventional fast recovery diodes. |
| Temperature-Stable Parameters | VF drift <0.05V from 25°C to 175°C at 30A; Qrr increases only 137% over same range - ensures predictable loss behavior across thermal transients. |
| Advanced Isolation | 2500VRMS isolation with 100% production-tested barrier - eliminates need for additional insulating hardware in drive PCB layouts. |
| Low LE (13nH) | Internal emitter inductance measured 5mm from case - reduces voltage overshoot during turn-off and eases snubber design. |
| Pb-Free & RoHS | Lead-free plating and full RoHS compliance - supports global environmental compliance without performance compromise. |
Applications
| Air Conditioning Inverters | General Purpose Drives (GPD) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage fast recovery diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IDW60C65D1XKSA1 | Same die, non-isolated TO-247 package; no heatsink isolation; Rth(j–h) = 0.9K/W (lower thermal resistance but no galvanic barrier). | Requires external isolation hardware (mica washer, silicone pad); unsuitable for safety-critical Class I systems without redesign. | Select when thermal performance is prioritized over safety certification and board space allows added isolation layers. |
| STTH60R06DJF | 600V/60A single-diode in TO-247; VF = 1.7V @ 30A; Qrr = 1.2µC; no integrated isolation; Tvjmax = 175°C. | Lacks dual-leg topology and isolation; requires two devices for equivalent functionality; higher conduction loss increases heatsink size by ~35%. | Choose only if dual-anode topology is unnecessary and existing layout accommodates discrete placement with external isolation. |
Compared with IDW60C65D1XKSA1 and STTH60R06DJF, IDFW60C65D1XKSA1 uniquely combines dual-leg integration, certified 2500VRMS isolation, and ECD-optimized Qrr/VF balance - reducing BOM count by one device and eliminating isolation hardware while maintaining 175°C operation.

FAQ
What is the maximum heatsink temperature for continuous 30A operation per leg?
At 30A per leg, the device sustains continuous operation with heatsink temperature ≤65°C, as confirmed by Figure 2 in the datasheet. Exceeding this requires current derating: 43A at Th=65°C and 56A at Th=25°C. Thermal design must account for Rth(j–h)=1.50K/W (typ) and ensure mounting torque of 0.6Nm on M3 screws.
Can Pin 1 (A1) and Pin 3 (A2) be used simultaneously in a phase-leg configuration?
Yes - A1 and A2 are fully independent anodes sharing only the cathode (Pin 2). They support true dual-leg operation in interleaved PFC or split-phase inverter topologies. Layout must maintain equal trace inductance to both anodes to preserve trr matching, as specified in the "Testing Conditions" section (Lσ = 30nH).
Does the 2500VRMS isolation rating apply to DC or only AC waveforms?
The 2500VRMS rating is validated per IEC 60747-5-1 at 50/60Hz for 1 minute and corresponds to ~3535VDC peak. For DC isolation, Infineon specifies a maximum working voltage of 1200VDC per UL 60747-5-1, confirmed in the "Isolation Characteristics" table of the datasheet revision V2.2.
How does the Emitter Controlled Diode technology differ from standard fast recovery diodes?
ECD uses localized lifetime control in the emitter region to decouple VF and Qrr optimization - achieving lower Qrr without increasing VF, unlike platinum/gold-doped diodes. This yields 35% lower Qrr than comparable FREDs at identical VF, directly reducing switching loss and EMI in hard-switched IGBT circuits.
