Product details
Overview
IDK03G65C5XTMA2 from Infineon is a 650 V, 3 A silicon carbide Schottky diode in PG-TO263-2 package, featuring zero reverse recovery charge, 5 nC capacitive charge at 400 V, 1.5–2.2 V forward voltage (3 A, 25–150°C), and 175°C max junction temperature. It serves as a high-efficiency freewheeling or output rectifier in high-frequency PFC stages of industrial SMPS.
For engineers reviewing the IDK03G65C5XTMA2 datasheet, IDK03G65C5XTMA2 pinout, IDK03G65C5XTMA2 application, or IDK03G65C5XTMA2 equivalent, key selection criteria include its SiC-specific thermal stability, avalanche-tested ruggedness, low Qc × Vf figure of merit, and compatibility with 650 V CoolMOS™ half-bridge topologies.
Technical Context
This 5th-generation thinQ!™ SiC Schottky diode uses Infineon's diffusion-soldered thin-wafer process to achieve lower thermal resistance (RthJC typ. 2.2 K/W) and improved efficiency across load conditions. Its unipolar conduction eliminates minority-carrier storage, enabling operation up to 175°C junction temperature without performance degradation.
The device exhibits temperature-independent switching behavior and dv/dt ruggedness of 100 V/ns under 0–480 V reverse bias. All units undergo 10 ms avalanche stress testing per JESD22, with breakdown voltage verified at 6.8 mA leakage current.
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 systems |
| IF (TC < 155°C) | 3 A - Continuous forward current rating at case temperature below 155°C; defines thermal derating envelope |
| VF @ 3 A, 25°C | 1.5–1.8 V - Forward voltage drop; directly impacts conduction loss and thermal design in high-frequency rectification |
| Qc @ VR = 400 V | 5 nC - Total capacitive charge; determines turn-off switching loss and EMI generation in hard-switched converters |
| RthJC | 2.2 K/W typ. - Junction-to-case thermal resistance; enables compact heatsink sizing for 42 W power dissipation |
| dv/dt Ruggedness | 100 V/ns - Maximum sustainable voltage transient rate; ensures robustness against parasitic ringing in fast-switching bridges |
| Tj Max | 175°C - Maximum junction temperature; supports high ambient operation without derating in sealed enclosures |
Pinout & Package
PG-TO263-2 (D²PAK) surface-mount package with isolated tab; cathode-connected tab provides low-inductance, high-current path and direct thermal interface to PCB copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Tab) | Cathode | Electrically and thermally connected metal tab; requires soldered copper pour for thermal management and current return path |
| Pin 2 | Anode | Controlled-impedance anode connection; routed with minimal loop area to reduce switching noise coupling |
| Pin 3 | Not assigned | No internal connection; mechanical support only; must remain unconnected and unshorted in layout |
Key Features
| Feature | Design Value |
|---|---|
| Zero reverse recovery charge | Eliminates switching tail current and associated losses, enabling >500 kHz operation without efficiency penalty |
| Temperature-stable VF | Forward voltage increases only ~0.4 V from 25°C to 150°C, simplifying thermal compensation in closed-loop control |
| Avalanche-rated construction | Guaranteed 10 ms non-repetitive avalanche energy handling per JEDEC JESD22-A109, supporting fault-tolerant designs |
| Thin-wafer + diffusion soldering | Reduces RthJC by 18% vs. Gen 4 and lowers Qc × Vf figure of merit for higher power density |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C3D03065E (Wolfspeed) | Same 650 V/3 A rating; TO-220AC package; 1.7 V VF @ 3 A, 25°C; 5.2 nC Qc | Through-hole mounting; higher RthJA (65 K/W); less suitable for ultra-thin SMD designs | Prefer when legacy through-hole assembly or higher creepage clearance is required |
| STPSC3065DLF (STMicroelectronics) | 650 V/3 A; TO-220AC; 1.6 V VF @ 3 A, 25°C; 4.8 nC Qc; 175°C Tj max | Higher IR at 650 V (1.2 µA vs. 0.6 µA at 150°C); slightly lower surge rating (25 A vs. 29 A) | Prefer when cost sensitivity outweighs marginal Qc advantage and thermal margin is sufficient |
Compared with C3D03065E and STPSC3065DLF, IDK03G65C5XTMA2 offers superior thermal performance (2.2 K/W RthJC vs. >3.5 K/W), optimized SMD footprint for automated assembly, and tighter Qc consistency across temperature-critical for high-density, air-cooled PFC modules.

FAQ
What is the maximum allowable case temperature for continuous operation?
The datasheet specifies IF = 3 A is rated for TC < 155°C. At 155°C case temperature, the device delivers full 3 A forward current while maintaining 175°C junction limit. Derating begins above this point per the IF vs. TC curve in Figure 7, with 0 A current allowed at 175°C case temperature.
Is the tab electrically isolated from the anode and cathode terminals?
No-the metal tab is internally connected to the cathode (Pin 1). It is not isolated and must be treated as a live, high-current terminal. Layout must ensure no unintended shorting to ground or adjacent signals; thermal pad must be connected only to cathode net and dedicated copper pour.
Does this diode require a gate resistor or external snubber network?
No-IDK03G65C5XTMA2 is a passive two-terminal Schottky diode with no gate. Its zero reverse recovery eliminates need for snubbers in most topologies. However, a small RC snubber (e.g., 10 Ω + 100 pF) across anode–cathode may be used to damp high-frequency ringing caused by stray inductance in high-di/dt layouts.
How does its surge current rating compare between 25°C and 150°C ambient?
At TC = 25°C, IF,SM = 31 A (10 ms sine half-wave); at TC = 150°C, it drops to 29 A. This minimal 6.5% reduction reflects excellent thermal stability-unlike silicon diodes, which typically lose >30% surge capability at elevated temperatures due to carrier lifetime degradation.
