Product details
Overview
IDFW80C65D1XKSA1 from Infineon Technologies is a dual-anode, single-cathode emitter-controlled Rapid-1 power diode in a fully isolated TO-247 package, rated for 650 V repetitive reverse voltage and 2 × 40 A forward current per leg. It delivers low VF (1.45–1.7 V @ 40 A, 25 °C), ultra-low Qrr (1.1 µC typ.), and stable switching behavior up to 175 °C junction temperature-optimized for high-efficiency industrial SMPS and motor drive freewheeling paths.
For engineers reviewing the IDFW80C65D1XKSA1 datasheet, IDFW80C65D1XKSA1 pinout, IDFW80C65D1XKSA1 application, or IDFW80C65D1XKSA1 equivalent, key selection criteria include its 2500 VRMS isolation rating, dual-anode configuration enabling interleaved or parallel-leg operation, temperature-stable reverse recovery characteristics, and Pb-free RoHS-compliant construction suitable for high-reliability thermal cycling environments.
Technical Context
This diode employs Infineon's Emitter Controlled Rapid-1 technology, integrating two independent diode legs sharing one cathode terminal while maintaining full electrical isolation between anode terminals and heatsink-mounting surface. Each leg operates with matched dynamic parameters-including trr (73 ns typ. @ 25 °C), Irrm (23.5 A), and dirr/dt (1500 A/µs)-enabling synchronous, low-loss commutation in bridge-leg configurations.
The PG-TO247-3-AI package provides 2500 VRMS isolation at 50/60 Hz for 1 minute, verified 100% on the mounting surface, with internal emitter inductance of only 13.0 nH (measured 5 mm from case). Its Rth(j-h) of 1.14–1.34 K/W supports high-power density designs when mounted on actively cooled heatsinks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - Enables use in 400 V AC input rectification and 600 V DC bus applications without derating. |
| IF (per leg) | 40 A continuous @ Th = 25 °C - Supports dual-leg 80 A total conduction capability with shared thermal path. |
| VF @ 40 A, 25 °C | 1.45–1.7 V - Reduces conduction loss by ~15% vs. standard fast recovery diodes in 10–50 kHz SMPS. |
| Qrr @ 40 A, 25 °C | 1.1 µC typ. - Minimizes turn-on switching loss in IGBT/MOSFET-based inverters and reduces EMI generation. |
| trr @ 40 A, 25 °C | 73 ns - Ensures clean zero-current switching in hard-switched PFC and motor drive boost stages. |
| Tvjmax | 175 °C - Allows sustained operation in enclosed industrial enclosures with limited airflow and high ambient temperatures. |
| Visol | 2500 VRMS @ 50/60 Hz, 1 min - Eliminates need for additional isolation barriers in safety-critical HVAC and drive systems. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-isolation, dual-anode fast recovery diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH806D | Single-anode TO-247; 600 V VRRM; no isolation; higher Qrr (2.5 µC) | Lacks dual-anode topology and 2500 VRMS isolation-requires external insulation and paralleling for same current handling | Select only if isolation is provided elsewhere in layout and cost sensitivity outweighs thermal/space advantages. |
| IXYS MDD85-16N1 | 1600 V VRRM; 85 A IF; non-isolated TO-247; higher VF (1.95 V) | Over-specified voltage rating increases cost and conduction loss; unsuitable where 650 V rating matches system design margin | Prefer only in 1200 V DC bus systems; avoid in 400 V AC input applications due to unnecessary VF penalty. |
Compared with STTH806D and MDD85-16N1, IDFW80C65D1XKSA1 uniquely combines dual-anode functionality, certified 2500 VRMS isolation, and sub-1.2 µC Qrr-making it the only drop-in solution for compact, high-efficiency, safety-certified industrial inverters requiring integrated dual-leg freewheeling.

FAQ
What is the maximum allowable heatsink temperature for continuous 40 A operation per leg?
At 40 A per leg, the maximum recommended heatsink temperature (Th) is 65 °C to maintain junction temperature ≤175 °C. Derating curves in the datasheet show IF drops to 59 A at Th = 65 °C and 74 A at Th = 25 °C. Thermal design must account for Rth(j-h) = 1.14–1.34 K/W and mounting torque of 0.6 Nm for M3 screws.
Can A1 and A2 be connected in parallel to increase current capacity?
No-A1 and A2 are electrically isolated terminals with separate die structures; paralleling them without external balancing resistors risks current imbalance due to parameter mismatch. The device is designed for independent leg operation in multi-phase topologies, not parallel conduction.
Does the 2500 VRMS isolation rating apply to all pin-to-heatsink combinations?
Yes-the 2500 VRMS isolation is certified between each anode (A1 and A2) and the heatsink-mounting surface, as well as between the cathode (C) and heatsink. The datasheet confirms 100% testing of the isolated mounting surface per unit, meeting IEC 60747-5-1 requirements.
How does the Emitter Controlled Rapid-1 technology improve reliability versus standard fast recovery diodes?
Emitter Controlled Rapid-1 uses localized lifetime control and optimized carrier distribution to suppress minority-carrier tail current, reducing Qrr by >50% and eliminating thermal runaway during reverse recovery. This yields 3× longer FIT rate in 150 °C operation compared to conventional FRDs, validated under JEDEC JESD22-A108 stress testing.
