Product details
Overview
IDK09G65C5XTMA1 from Infineon is a 650 V, 9 A silicon carbide Schottky diode in PG-TO263-2 package, designed for high-frequency, high-temperature switching in power conversion stages. It delivers zero reverse recovery charge, 14 nC capacitive charge at 400 V, and 1.5–1.8 V forward voltage at 9 A and 25°C, enabling PFC and solar inverter designs operating up to 175°C junction temperature.
For engineers reviewing the IDK09G65C5XTMA1 datasheet, IDK09G65C5XTMA1 pinout, IDK09G65C5XTMA1 application, or IDK09G65C5XTMA1 equivalent, key selection criteria include its 650 V repetitive peak reverse voltage, 75 A surge current capability at 25°C, thermal resistance of 1.1 K/W (junction-to-case), and RoHS-compliant Pb-free lead plating.
Technical Context
This 5th-generation thinQ!™ SiC Schottky diode uses Infineon's diffusion-soldered thin-wafer technology to achieve lower Qc × Vf figure of merit and improved thermal performance over prior generations. Its unipolar conduction eliminates minority-carrier storage, resulting in temperature-independent switching and no reverse recovery loss.
The device is optimized for complementary use with 650 V CoolMOS™ MOSFETs in hard-switched topologies. Its dv/dt ruggedness of 100 V/ns and 28 A²s i²t rating support robust operation under fast transient conditions in SMPS and UPS systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - Maximum repetitive reverse voltage; defines safe blocking capability in PFC boost or inverter DC-link applications |
| IF (TC < 145°C) | 9 A - Continuous forward current rating at case temperature below 145°C; sets thermal design margin for heatsink sizing |
| VF @ 9 A, 25°C | 1.5–1.8 V - Forward voltage drop; directly impacts conduction loss and system efficiency at nominal load |
| Qc @ 400 V | 14 nC - Total capacitive charge; determines turn-off switching loss and EMI behavior in high-dv/dt circuits |
| RthJC | 1.1–1.8 K/W - Junction-to-case thermal resistance; enables accurate junction temperature estimation from measured case temperature |
| IR @ 650 V, 150°C | 1.8–1100 µA - Reverse leakage current range; critical for high-temperature hold-off stability in solar string inverters |
| dv/dt | 100 V/ns - Rated voltage transient immunity; ensures reliable operation during fast MOSFET switching edges |
Pinout & Package
Package: PG-TO263-2 (D²PAK), surface-mount, single-diode configuration with isolated cathode tab. Thermal pad on underside requires soldering to PCB copper area for optimal heat transfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Cathode) | Anode-side return path for forward current | Primary thermal interface; must be connected to ≥6 cm² copper pour for rated 82 W power dissipation |
| Pin 2 (Anode) | Current entry point during forward conduction | Low-inductance connection point; routed away from sensitive control traces to minimize coupling |
| Pin 3 (n.a.) | Not assigned / No internal connection | Unused terminal; electrically floating and thermally isolated - must not be soldered or shorted |
Key Features

|---|---|
| No reverse recovery | Eliminates switching loss and associated EMI in hard-switched converters; enables >100 kHz operation without snubbers |
| Temperature-independent switching | Enables consistent timing and loss profiles across -55°C to 175°C ambient, simplifying thermal derating |
| 75 A surge current (10 ms) | Supports inrush current handling in UPS and industrial SMPS without external crowbar protection |
| Diffusion-soldered die attach | Reduces interfacial thermal resistance by >30% vs. standard solder, improving long-term reliability under thermal cycling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C3D09065A (Wolfspeed) | Same 650 V/9 A rating; higher VF (1.7–2.1 V at 9 A, 25°C); 16 nC Qc | Slightly higher conduction loss; less suitable for ultra-high-efficiency PFC where <1.6 V VF is critical | Prefer when legacy layout compatibility with TO-220AC footprint is required |
| STPSC9H065D (STMicroelectronics) | 650 V/9 A; VF = 1.6–1.95 V; Qc = 15 nC; RthJC = 1.5 K/W | Higher thermal resistance limits power density in compact SMD designs | Choose when dual-diode configuration or integrated Kelvin sense is needed |
Compared with C3D09065A and STPSC9H065D, IDK09G65C5XTMA1 offers the lowest combined Qc × Vf figure of merit and tightest VF distribution, making it optimal for space-constrained, high-frequency PFC and solar inverter designs demanding minimal thermal overhead.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The IDK09G65C5XTMA1 supports continuous operation up to 175°C junction temperature, verified per JEDEC qualification standards. Derating begins at TC = 145°C, where IF drops linearly to zero at 175°C. This rating enables deployment in sealed, fanless enclosures common in solar and industrial UPS systems.
Does this diode require a gate resistor or snubber network?
No. As a unipolar Schottky diode, IDK09G65C5XTMA1 has no gate and exhibits no reverse recovery, eliminating the need for snubbers or damping resistors. However, layout best practices-such as minimizing loop inductance and separating high-di/dt paths from control traces-are still essential to manage EMI from rapid current transitions.
How does the 1.1–1.8 K/W RthJC range impact thermal design?
The RthJC range reflects process variation in die attach quality and package molding. For worst-case thermal design, use 1.8 K/W to calculate junction temperature: Tj = TC + (Pdiss × 1.8). At 9 A and 1.7 V VF, Pdiss ≈ 15.3 W, so TC must stay ≤ 85°C to keep Tj ≤ 175°C-guiding heatsink selection and airflow requirements.
Can IDK09G65C5XTMA1 replace silicon diodes in existing designs without layout changes?
Yes, if the PCB footprint matches PG-TO263-2 and thermal copper area meets Infineon's 6 cm² recommendation. Electrical replacement is drop-in for most 650 V Si FRDs, but layout review is mandatory: reduced switching loss lowers EMI filter burden, while higher dv/dt may expose parasitic coupling not previously problematic with slower silicon devices.
