Product details
Overview
IDK04G65C5XTMA1 from Infineon is a 650 V, 4 A silicon carbide Schottky diode in PG-TO263-2 package, designed for high-frequency switching in power conversion stages. It delivers zero reverse recovery charge, 1.5–2.2 V forward voltage at 4 A across -55°C to 150°C, and 7 nC capacitive charge at 400 V, enabling PFC and solar inverter designs requiring high efficiency and thermal robustness.
For engineers reviewing the IDK04G65C5XTMA1 datasheet, IDK04G65C5XTMA1 pinout, IDK04G65C5XTMA1 application, or IDK04G65C5XTMA1 equivalent, key selection criteria include its SiC-specific thermal stability, avalanche-tested ruggedness (10 ms), 650 V repetitive peak reverse voltage, and compatibility with CoolMOS™ 650 V systems.
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 (RthJC typ. 1.9 K/W). Its unipolar conduction eliminates minority-carrier storage, resulting in temperature-independent switching and no forward/reverse recovery transients.
The device is rated for 38 A non-repetitive surge current at 25°C (10 ms), supports dv/dt up to 100 V/ns, and operates reliably from -55°C to +175°C junction temperature-enabling compact, high-power-density topologies without forced cooling.
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 DC bus solar inverters. |
| IF (TC < 150°C) | 4 A - Continuous forward current rating at case temperature below 150°C; defines steady-state conduction capability. |
| VF @ 4 A, 25°C | 1.5–1.8 V - Forward voltage drop; directly impacts conduction loss and thermal design in high-efficiency SMPS. |
| Qc @ VR = 400 V | 7 nC - Total capacitive charge; determines turn-off switching loss and EMI behavior in hard-switched converters. |
| RthJC | 1.9 K/W (typ.) - Junction-to-case thermal resistance; enables accurate thermal modeling for heatsink sizing. |
| IR @ 650 V, 150°C | ≤500 µA - High-temperature reverse leakage; ensures stable blocking under elevated ambient conditions. |
| dv/dt ruggedness | 100 V/ns - Maximum tolerable voltage transient slope; critical for reliability in fast-switching GaN/CoolMOS™ half-bridges. |
Pinout & Package
Package: PG-TO263-2 (D²PAK), surface-mount, single-diode configuration with isolated cathode tab. Thermal pad on underside requires soldered copper area (≥6 cm²) for optimal RthJC performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Cathode) | Anode-side return path | Electrically connected to metal tab; primary thermal and current path-must be soldered to large PCB copper pour. |
| Pin 2 (Anode) | Forward current entry | Leads to internal SiC die anode; routed as low-inductance trace to minimize switching overshoot. |
| Pin 3 (n.a.) | Not assigned | No internal connection; mechanical placeholder only-no electrical or thermal function. |
Key Features
| Feature | Design Value |
|---|---|
| Zero reverse recovery charge (Qrr = 0) | Eliminates switching tail current and associated losses-reducing MOSFET turn-on loss in synchronous rectification. |
| Temperature-stable VF and switching | Forward voltage increases only ~0.4 V from 25°C to 150°C; enables predictable loss modeling across full operating range. |
| Avalanche-rated (10 ms) | Guaranteed energy handling under transient overvoltage-supports robust operation in UPS and motor drive clamp circuits. |
| RoHS-compliant Pb-free plating | Meets global environmental compliance without compromising solder joint reliability or wirebond interface integrity. |
| Optimized for 650 V CoolMOS™ pairing | Designed to match dynamic characteristics and thermal profiles of Infineon's 650 V superjunction MOSFETs for seamless system integration. |

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; higher VF (1.7–2.3 V @ 4 A); 8.5 nC Qc; TO-220AC package. | Larger footprint and higher RthJA (40 K/W); less suitable for ultra-dense SMD layouts. | Prefer when legacy through-hole assembly or higher surge margin (45 A) is required. |
| STPSC4H065DL (STMicroelectronics) | 650 V/4 A; VF 1.5–1.9 V; Qc 6.5 nC; same PG-TO263-2 package; lower IR (≤100 µA @ 650 V, 150°C). | Better high-temp leakage but slightly lower dv/dt rating (75 V/ns vs. 100 V/ns). | Prefer for high-ambient-temperature UPS where leakage-induced standby loss is critical. |
Compared with C3D04065E and STPSC4H065DL, IDK04G65C5XTMA1 offers the lowest Qc × Vf figure of merit, highest dv/dt ruggedness, and optimized thermal interface for SMD-based high-power-density designs-making it ideal for next-gen PFC and solar inverters where layout space and EMI are constrained.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The IDK04G65C5XTMA1 has a maximum junction temperature of 175°C, validated per JEDEC standards. Continuous operation at this limit requires strict thermal design: case temperature must remain below 150°C, and the PCB must provide ≥6 cm² of 70 µm copper on the cathode pad to maintain RthJC ≤3.1 K/W.
Does this diode require a gate driver or external control circuitry?
No. As a passive unipolar Schottky diode, IDK04G65C5XTMA1 conducts automatically when forward-biased and blocks when reverse-biased-no gate signal, biasing, or control logic is needed. Its operation depends solely on applied voltage polarity and magnitude relative to its 650 V VRRM rating.
How does its avalanche ruggedness compare to standard silicon diodes?
IDK04G65C5XTMA1 is tested for 10 ms avalanche stress at rated current, unlike most Si diodes which lack specified avalanche capability. This ruggedness stems from SiC's wide bandgap and inherent material robustness-allowing safe operation during inductive switching transients without derating or snubber networks.
Can it replace a silicon fast recovery diode in an existing 650 V design without layout changes?
Yes-IDK04G65C5XTMA1 uses the industry-standard PG-TO263-2 (D²PAK) footprint and pinout. However, thermal relief pads and copper area under the cathode tab must be verified for adequacy, as SiC's higher thermal conductivity demands more aggressive heat spreading than typical Si FRDs.
