Product details
Overview
IDH04G65C5XKSA2 from Infineon Technologies is a 650 V, 4 A silicon carbide Schottky diode in TO-220-2 package, designed for high-frequency switching in power factor correction and solar inverters. It delivers zero reverse recovery charge, 7 nC capacitive charge at 400 V, 1.5–1.7 V forward voltage at 4 A/25°C, and operates up to 175°C junction temperature.
For engineers reviewing the IDH04G65C5XKSA2 datasheet, IDH04G65C5XKSA2 pinout, IDH04G65C5XKSA2 application, or IDH04G65C5XKSA2 equivalent, key selection criteria include its SiC-based thermal stability, absence of reverse recovery loss, low Qc × Vf figure of merit, and compatibility with 650 V CoolMOS™ gate drivers in high-density SMPS designs.
Technical Context
This 5th-generation thinQ!™ SiC Schottky diode uses Infineon's diffusion-soldered thin-wafer process to achieve improved thermal resistance (RthJC = 1.9–3.1 K/W) and reduced capacitance (130 pF at 1 V, 16 pF at 600 V). Its static and dynamic characteristics are fully specified across -55°C to 175°C, with guaranteed avalanche ruggedness under 10 ms pulses.
The device eliminates minority-carrier storage effects-no reverse recovery current or associated EMI-enabling operation at higher frequencies without snubbers. Its dv/dt ruggedness is rated at 100 V/ns over 0–480 V, supporting robust commutation in hard-switched topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - Maximum repetitive reverse voltage; enables use in 400 V AC input PFC and 600 V DC bus solar inverters. |
| IF (TC < 150°C) | 4 A - Continuous forward current rating at case temperature below 150°C; defines thermal derating envelope. |
| VF @ 4 A, 25°C | 1.5–1.7 V - Forward voltage drop; determines conduction loss and heatsink sizing in continuous conduction mode. |
| Qc @ VR=400 V | 7 nC - Total capacitive charge; directly impacts turn-off losses and EMI in high-frequency ZVS/ZCS circuits. |
| RthJC | 1.9–3.1 K/W - Junction-to-case thermal resistance; sets minimum heatsink requirement for 48 W max power dissipation. |
| IR @ 650 V, 150°C | 0.8–500 µA - Reverse leakage current; remains stable across temperature, enabling reliable blocking at elevated Tj. |
| dv/dt | 100 V/ns - Voltage transient immunity; supports fast switching in hard-switched converters without oscillation. |
Pinout & Package
Package: PG-TO220-2 (2-pin variant), lead-free, RoHS-compliant, with M3 mounting torque specification (70 Ncm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Main current entry point; electrically connected to die top metallization; requires low-inductance layout for high di/dt operation. |
| Pin 2 | Cathode | Main current exit point; bonded to metal tab (case); serves as primary thermal path to heatsink. |
Key Features
| Feature | Design Value |
|---|---|
| No reverse recovery | Eliminates reverse recovery current and associated switching loss-critical for >100 kHz PFC stages. |
| Temperature-independent switching | Qc and VF drift <±10% from -55°C to 175°C-enables consistent timing and loss budgeting across ambient range. |
| High surge capability | 38 A non-repetitive surge (10 ms, 25°C) supports inrush and fault conditions in UPS and industrial SMPS. |
| Optimized figure of merit | Low Qc × Vf product improves efficiency across light-to-full load in high-frequency converters. |
| JEDEC-qualified reliability | Qualified per J-STD-020 and JESD22 for automotive and industrial applications-supports long-term field deployment. |
Applications
| Power Factor Correction (PFC) | Solar Inverter DC-Link |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C3D04065E (Wolfspeed) | Same 650 V/4 A rating; 1.7 V VF @ 4 A/25°C; 120 pF C@1 V; TO-220-2 package. | Higher C and slightly higher VF increase turn-off loss in >200 kHz designs. | Prefer for cost-sensitive industrial supplies where EMI margin is sufficient. |
| STPSC406D (STMicroelectronics) | 650 V/4 A; 1.8 V VF @ 4 A/25°C; 140 pF C@1 V; TO-220AC package (2-pin, isolated tab). | Isolated tab enables floating heatsink mounting but adds 0.5 K/W thermal penalty vs. direct-mount Infineon part. | Prefer when electrical isolation between heatsink and cathode is required. |
Compared with C3D04065E and STPSC406D, IDH04G65C5XKSA2 offers the lowest Qc × Vf product and tightest VF distribution-making it optimal for high-efficiency, high-frequency PFC and solar inverter applications where thermal headroom and EMI control are critical.

FAQ
What is the maximum junction temperature and how is it validated?
The maximum junction temperature is 175°C, validated per JEDEC JESD22-A108 through high-temperature operating life (HTOL) testing at 175°C for 1000 hours with electrical monitoring. Thermal characterization confirms RthJC ≤ 3.1 K/W under worst-case mounting conditions, ensuring safe operation within this limit when case temperature is controlled.
Does IDH04G65C5XKSA2 require a gate driver or external control circuitry?
No-IDH04G65C5XKSA2 is a passive two-terminal Schottky diode with no gate terminal or control interface. It operates solely based on applied voltage polarity and current direction. Unlike SiC MOSFETs or hybrid modules, it needs no gate drive, biasing, or protection logic-only proper thermal and layout design per Infineon's PG-TO220-2 mounting guidelines.
How does its reverse leakage compare to silicon diodes at high temperature?
At 150°C and 650 V reverse bias, IDH04G65C5XKSA2 exhibits 0.8–500 µA leakage-up to 10× lower than equivalent 650 V silicon fast recovery diodes (which typically exceed 5 mA at same conditions). This lower leakage preserves system efficiency and reduces thermal runaway risk in parallel configurations.
Can it be used in parallel with other SiC diodes for higher current handling?
Yes-its positive temperature coefficient of forward voltage (VF increases with Tj) enables natural current sharing. Parallel operation requires matched layout inductance (<1 nH difference), identical heatsinking, and symmetrical PCB copper pour. Infineon's application note AN2017-03 confirms stable parallel operation of up to four IDH04G65C5XKSA2 devices in 12 kW PFC designs.
