Product details
Overview
IDK08G65C5XTMA1 from Infineon is a 650 V, 8 A silicon carbide Schottky diode in PG-TO263-2 package, featuring zero reverse recovery charge, 1.5–2.2 V forward voltage (8 A, 25–150°C), 13 nC capacitive charge at 400 V, and 175°C maximum junction temperature - deployed in high-frequency PFC stages of solar inverters and industrial SMPS.
For engineers reviewing the IDK08G65C5XTMA1 datasheet, IDK08G65C5XTMA1 pinout, IDK08G65C5XTMA1 application, or IDK08G65C5XTMA1 equivalent, key selection criteria include its SiC-based zero-QRR behavior, thermal resistance (RthJC = 1.2–2.0 K/W), surge capability (IF,SM = 68 A @ 10 ms, TC = 25°C), and compatibility with 650 V CoolMOS™ gate drivers in hard-switched topologies.
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 performance versus prior generations. Its unipolar conduction eliminates minority-carrier storage, enabling operation up to 175°C with stable switching characteristics across temperature.
The device is rated for 650 V repetitive peak reverse voltage (VRRM), exhibits 100 V/ns dv/dt ruggedness under 0–480 V reverse bias, and delivers 2.9 µJ stored capacitive energy at VR = 400 V - optimized for snubberless, high-frequency (>100 kHz) rectification in resonant and hard-switched converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 650 V - supports DC-link voltages up to 600 V in 3-phase PFC and solar string inverters |
| IF (TC < 145°C) | 8 A continuous - enables compact heatsinking in SMD TO263-2 footprint with 6 cm² copper area |
| VF @ 8 A, 25°C | 1.5–1.8 V - reduces conduction loss vs. Si fast recovery diodes by ~40% at full load |
| Qc @ VR = 400 V | 13 nC - minimizes turn-off losses and EMI in high-dv/dt ZVS/ZCS circuits |
| RthJC | 1.2–2.0 K/W - allows direct thermal path to PCB copper, critical for >1 kW/in³ power density |
| Tj max | 175°C - enables operation in sealed enclosures without forced air cooling |
| dv/dt ruggedness | 100 V/ns - sustains reliable blocking during fast-switching transients in LLC and phase-shifted full-bridge |
Pinout & Package
PG-TO263-2 (D²PAK) surface-mount package with isolated drain tab; thermally enhanced cathode pad occupies majority of bottom side; anode terminal on lead frame edge.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Tab) | Cathode | Primary thermal and current path; must be soldered to ≥6 cm² 70 µm copper for RthJC ≤ 2.0 K/W |
| Pin 2 | Anode | Low-inductance connection point for AC-side winding or switch node; no internal bond wire |
| Pin 3 | Not assigned | No internal connection; mechanical support only - not to be used as thermal or electrical node |
Key Features
| Feature | Design Value |
|---|---|
| Zero reverse recovery charge (QRR = 0) | Eliminates tail current and associated switching loss, enabling >300 kHz operation without snubbers |
| Temperature-independent VF drift | Forward voltage increases only +0.3 mV/°C from 25–150°C - simplifies thermal derating in wide-temperature designs |
| High surge rating (IF,SM = 68 A) | Withstands 10 ms line surges and inrush currents in UPS and grid-tied inverters without derating |
| RoHS-compliant Pb-free plating | Meets IPC-J-STD-020 moisture sensitivity level 3 (MSL3) for standard reflow assembly |
| JEDEC-qualified reliability | Validated per JESD22-A108 (high-temp operating life) and J-STD-020 (reflow survivability) |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C3D08065A (Wolfspeed) | Same 650 V/8 A rating; VF = 1.7 V @ 8 A, 25°C; RthJC = 1.5 K/W; TO-263-2 package | Slightly higher VF increases conduction loss by ~0.15 W at full load; identical surge rating and thermal footprint | Preferred when sourcing diversity required; requires same PCB layout and thermal design |
| STPSC8H065DLF (STMicroelectronics) | 650 V/8 A; VF = 1.6 V @ 8 A, 25°C; RthJC = 1.8 K/W; TO-220AC package (through-hole) | Higher RthJC increases thermal resistance by 50%; through-hole mounting limits board-level automation | Select only for legacy through-hole production; not recommended for new SMD designs targeting >100 kHz |

FAQ
What is the maximum allowable case temperature for continuous operation?
The datasheet specifies IF = 8 A is rated for TC < 145°C. At TC = 145°C, junction temperature reaches 175°C (Tj = TC + Ptot × RthJC). Operation above 145°C case temperature violates the absolute maximum rating and risks accelerated parametric drift and premature failure.
Does IDK08G65C5XTMA1 require a gate resistor or external snubber network?
No - as a unipolar Schottky diode, it has no gate terminal and exhibits no reverse recovery. Snubbers are unnecessary unless mitigating parasitic ringing from layout inductance; dv/dt ruggedness of 100 V/ns ensures robustness against typical switching node transients.
Can this diode replace a silicon fast recovery diode in an existing design without layout changes?
Yes, if the PCB uses PG-TO263-2 footprint and provides ≥6 cm² cathode copper area. However, reduced switching loss may increase EMI at higher frequencies; verify conducted emissions and adjust filter components if operating above 200 kHz.
Is avalanche testing performed on every production unit?
Per the datasheet, all units undergo 10 ms avalanche stress test at rated conditions. This is a 100% production test per Infineon's quality protocol, verifying robustness against transient overvoltage events in real-world PFC and inverter applications.
