Product details
Overview
IDW10G65C5XKSA1 from Infineon is a 650 V, 10 A silicon carbide Schottky diode in TO-247-3 package, featuring zero reverse recovery charge, 15 nC capacitive charge at 400 V, and operation up to 175 °C junction temperature. It serves as a high-efficiency freewheeling or output rectifier in high-frequency switch-mode power supplies and solar inverters.
For engineers reviewing the IDW10G65C5XKSA1 datasheet, IDW10G65C5XKSA1 pinout, IDW10G65C5XKSA1 application, or IDW10G65C5XKSA1 equivalent, key selection criteria include its 650 V repetitive peak reverse voltage, 1.5–1.7 V forward voltage at 10 A/25 °C, 1.8–2.1 V at 150 °C, 175 °C max operating temperature, and 1.8 K/W typical thermal resistance (junction-to-case).
Technical Context
This SiC Schottky diode replaces conventional silicon fast recovery diodes in high-voltage, high-frequency power conversion stages. Its unipolar conduction eliminates minority-carrier storage, enabling true zero reverse recovery time and immunity to temperature-induced switching degradation.
The device uses Infineon's 5th Generation thinQ!™ technology with thin-wafer processing to reduce Qc × Vf figure of merit. It is co-designed with 650 V CoolMOS™ MOSFETs to optimize system-level efficiency in PFC and DC-DC stages where dv/dt ruggedness up to 100 V/ns is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - Maximum repetitive reverse blocking voltage; enables use in 400 V AC input PFC and 600 V bus DC-DC converters |
| IF (TC < 130°C) | 10 A - Continuous forward current rating at case temperature below 130 °C; defines thermal design margin for heatsink sizing |
| VF @ 10 A, 25°C | 1.5–1.7 V - Forward voltage drop; directly impacts conduction loss and thermal load in high-duty-cycle applications |
| Qc @ VR=400 V | 15 nC - Total capacitive charge; determines turn-on switching loss when commutated by a MOSFET or IGBT |
| RthJC | 1.8–2.3 K/W - Junction-to-case thermal resistance; used to calculate ΔTj from measured case temperature in thermal modeling |
| Tj max | 175 °C - Maximum allowable junction temperature; supports high ambient operation without derating in compact enclosures |
| dv/dt ruggedness | 100 V/ns - Rated voltage transient immunity; ensures reliable operation during fast-switching transitions in hard-switched topologies |
Pinout & Package
Package: PG-TO247-3 (standard through-hole power package with isolated tab, pin 2 = cathode, pin 3 = anode, pin 1 = no connection).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | No connection (n.c.) | Electrically isolated terminal; must not be soldered or connected to avoid mechanical stress or unintended coupling |
| Pin 2 | Cathode | Main current exit path; electrically tied to metal tab; requires thermal interface to heatsink for power dissipation |
| Pin 3 | Anode | Main current entry path; connects to high-side switching node or transformer secondary in flyback/LLC topologies |
Key Features
| Feature | Design Value |
|---|---|
| Zero reverse recovery charge (Qrr = 0) | Eliminates switching losses and associated EMI during diode turn-off; enables clean hard-switching at >100 kHz |
| Temperature-independent switching behavior | Forward voltage and capacitance remain stable across -55 °C to 175 °C; simplifies control loop compensation over wide thermal range |
| High surge current capability (IF,SM = 58 A @ 10 ms) | Withstands inrush and overload transients without failure; reduces need for external current-limiting protection |
| RoHS-compliant Pb-free plating | Meets global environmental compliance requirements; compatible with standard lead-free reflow and wave soldering processes |
| JEDEC-qualified reliability | Validated per J-STD-020 and JESD22 for automotive and industrial applications; supports long-term field deployment |
Applications
| Power Factor Correction (PFC) | Solar Inverter DC-AC Stage |
|---|---|
Use Scenario: Boost PFC stage in 3–5 kW server PSU or telecom rectifier. IC Role / Device Role / Timing Role: Output rectifier conducting during MOSFET off-time; handles continuous 10 A RMS current at 100 kHz switching frequency. Use Value: 15 nC Qc minimizes turn-on loss in synchronous boost; 175 °C rating allows smaller heatsink versus Si diode alternatives. | Use Scenario: Freewheeling diode in H-bridge inverter leg for single-phase residential PV systems.

IC Role / Device Role / Timing Role: Regenerative energy return path from motor back-EMF to DC link during deceleration. Use Value: High surge current rating (58 A) absorbs regenerative spikes without derating; 1.8 K/W RthJC enables direct mounting to shared heatsink. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C3D10065A (Wolfspeed) | Same 650 V/10 A rating; VF = 1.8 V typ. @ 10 A/25°C; Qc = 17 nC @ 400 V; TO-247-2 package (no n.c. pin) | Lacks isolated pin 1; requires different PCB layout and thermal pad routing | Select if board space permits simplified 2-pin footprint and lower Qc tolerance is acceptable |
| STPSC10H065D (STMicroelectronics) | 650 V/10 A; VF = 1.7 V @ 10 A/25°C; Qc = 14 nC @ 400 V; same TO-247-3 pinout but pin 1 = cathode (not n.c.) | Pin 1 functional (cathode), altering circuit topology compatibility and requiring schematic revision | Choose only when redesigning for ST's dual-cathode configuration and tighter Qc spec is critical |
Compared with C3D10065A and STPSC10H065D, IDW10G65C5XKSA1 offers a unique no-connect pin 1 for mechanical stability and isolation, lower VF at high temperature (1.8–2.1 V @ 150 °C), and JEDEC qualification aligned with Infineon's CoolMOS™ ecosystem for seamless PFC + switching stage integration.

FAQ
What is the maximum allowable case temperature for continuous operation?
The datasheet specifies IF = 10 A is rated for TC < 130 °C. At higher case temperatures, current must be linearly derated to maintain Tj ≤ 175 °C. For example, at TC = 150 °C, maximum continuous IF drops to approximately 7.2 A based on RthJC = 2.3 K/W and thermal margin calculation.
Is pin 1 electrically connected internally?
No - pin 1 is explicitly designated "n.c." (no connection) in the official Infineon datasheet and package outline. It is mechanically present for mounting stability but has no internal bond wire or semiconductor connection. Soldering or wiring to pin 1 is not recommended and may compromise mechanical integrity.
How does the diode perform under avalanche conditions?
All units are tested under controlled avalanche conditions for 10 ms per the final datasheet. The device is not rated for repetitive avalanche operation. Avalanche testing verifies robustness during single-event overvoltage transients, but sustained operation beyond VRRM is not guaranteed and may cause permanent degradation.
Can this diode replace a silicon fast recovery diode in an existing design?
Yes - it can serve as a drop-in replacement in TO-247-3 sockets, provided layout accommodates zero Qrr benefits: snubber networks may be reduced or removed, gate drive strength should be verified for faster commutation, and thermal interface must handle higher localized power density due to lower VF and improved RthJC.
