Product details
Overview
IDH12G65C5XKSA1 from Infineon is a 650 V, 12 A silicon carbide Schottky diode in TO-220-2 package, featuring zero reverse recovery charge, 18 nC capacitive charge at 400 V, 1.5–2.1 V forward voltage across 25–150 °C, and 104 W power dissipation at 25 °C case temperature. It operates reliably up to 175 °C junction temperature and is qualified per JEDEC standards for high-efficiency switch-mode power supplies and solar inverters.
For engineers reviewing the IDH12G65C5XKSA1 datasheet, IDH12G65C5XKSA1 pinout, IDH12G65C5XKSA1 application, or IDH12G65C5XKSA1 equivalent, this SiC diode delivers verified thermal robustness (RthJC = 0.9–1.5 K/W), surge current capability (97 A @ 10 ms, TC = 25 °C), and temperature-independent switching behavior critical for PFC and UPS designs.
Technical Context
This 5th-generation thinQ!™ SiC Schottky diode uses Infineon's diffusion-soldered thin-wafer process to achieve lower QC × VF figure of merit and improved thermal resistance versus prior generations. Its unipolar conduction eliminates minority-carrier storage, enabling true zero reverse recovery and stable dv/dt ruggedness up to 100 V/ns.
The device is optimized as a high-frequency freewheeling or boost diode paired with 650 V CoolMOS™ MOSFETs. Its 650 V VRRM, 175 °C max junction temperature, and 360–47 pF capacitance (1–600 V) support operation in hard-switched topologies with minimal EMI generation and reduced snubber requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - Rated blocking voltage ensures safe operation in 400 V AC input PFC and 600 V DC bus solar inverters. |
| IF (TC < 140 °C) | 12 A - Continuous forward current rating defines maximum steady-state conduction without derating at heatsink temperatures below 140 °C. |
| QC @ VR = 400 V | 18 nC - Capacitive charge directly impacts turn-on losses in synchronous rectification and determines gate drive energy requirements. |
| VF @ IF = 12 A | 1.5–2.1 V - Forward voltage range across 25–150 °C enables predictable conduction loss modeling in thermal simulation. |
| RthJC | 0.9–1.5 K/W - Junction-to-case thermal resistance governs heatsink sizing and sets upper bound on allowable power dissipation at given TC. |
| IF,SM @ tp = 10 ms | 97 A @ 25 °C - Non-repetitive surge rating validates short-circuit withstand in UPS and motor drive clamp circuits. |
| C @ VR = 600 V | 47 pF - Reverse-biased capacitance value determines resonant frequency with circuit inductance and influences EMI filter design. |
Pinout & Package
Package: PG-TO220-2 (2-pin, isolated tab), lead-free, RoHS-compliant, with mounting torque specification of 70 Ncm for M3 screws.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Tab) | Cathode | Electrically connected to metal tab; must be electrically isolated from heatsink unless system ground reference requires cathode tie. |
| Pin 2 | Anode | Standard anode terminal; connects to switching node (e.g., MOSFET drain in boost PFC) for unidirectional current flow. |
| Pin 3 | n.a. | No connection - mechanical dummy pin not used for electrical function; omitted in TO-220-2 footprint. |
Key Features
| Feature | Design Value |
|---|---|
| Zero reverse recovery charge (Qrr = 0) | Eliminates commutation losses and associated EMI spikes during hard switching, enabling >100 kHz operation without snubbers. |
| Temperature-independent switching | Forward voltage and switching characteristics remain stable from –55 °C to 175 °C, simplifying control loop compensation across ambient extremes. |
| High surge current capability (97 A, 10 ms) | Withstands line transients and inrush events in industrial UPS and grid-tied solar inverters without derating or external protection. |
| Low QC × VF figure of merit | Combines low capacitive charge (18 nC) and moderate VF (1.5–2.1 V) to minimize total conduction + switching loss across full load range. |
| JEDEC-qualified reliability | Validated per J-STD-020 and JESD22 for moisture sensitivity, temperature cycling, and avalanche stress-ensuring field longevity in mission-critical power systems. |
Applications

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 but TO-247-2L package; higher VF (1.7–2.3 V) and QC (22 nC). | Larger footprint and higher thermal resistance (RthJC = 1.7 K/W) limit use in space-constrained TO-220 layouts. | Select when higher surge rating (110 A) justifies larger package and added cost. |
| STPSC12065DL (STMicroelectronics) | 12 A/650 V in TO-220AC; slightly lower VF (1.4–2.0 V) but higher QC (24 nC) and no JEDEC qualification data published. | Lower conduction loss at light loads but increased switching loss above 50 kHz due to higher QC. | Select for cost-sensitive designs where JEDEC qualification is not mandated and EMI filtering budget allows. |
Compared with C3D10065A and STPSC12065DL, IDH12G65C5XKSA1 offers the lowest QC × VF product in TO-220-2, JEDEC-validated reliability, and optimal thermal performance for compact, high-reliability PFC and solar applications.

FAQ
Is IDH12G65C5XKSA1 pin-compatible with standard TO-220-2 silicon diodes?
Yes - it uses the same PG-TO220-2 mechanical outline and pin assignment (cathode tab, anode lead), allowing direct PCB footprint reuse. However, its higher dv/dt ruggedness (100 V/ns) and absence of reverse recovery require verification of gate driver layout and snubber design to avoid false triggering in half-bridge configurations.
What is the maximum recommended case temperature for continuous 12 A operation?
The datasheet specifies IF = 12 A is rated for TC < 140 °C. At TC = 140 °C, junction temperature reaches 175 °C (max), leaving no thermal margin. For reliable long-term operation, maintain TC ≤ 125 °C using appropriate heatsinking and airflow to ensure <150 °C Tj.
Does IDH12G65C5XKSA1 require a negative gate voltage or special driving circuitry?
No - as a diode, it has no gate and requires no drive circuitry. Its anode and cathode terminals connect directly in series with the power path. The only design considerations are thermal interface quality to the heatsink (due to isolated tab) and layout parasitics affecting high-di/dt transient response.
How is avalanche robustness validated for IDH12G65C5XKSA1?
All units undergo 10 ms avalanche stress testing at rated VRRM with IF = 27 mA per JEDEC JESD22-A106. This verifies ability to absorb inductive energy without parametric shift or catastrophic failure, supporting use in flyback and LLC resonant converters where voltage overshoot may occur.
