Product details
Overview
IDK08G65C5XTMA2 from Infineon is a 650 V, 8 A silicon carbide Schottky diode in PG-TO263-2 package, featuring zero reverse recovery charge, 13 nC capacitive charge at 400 V, 2.9 µJ stored energy, and operation up to 175 °C junction temperature. It serves as a high-efficiency freewheeling or output rectifier in high-frequency switch-mode power supplies.
For engineers reviewing the IDK08G65C5XTMA2 datasheet, IDK08G65C5XTMA2 pinout, IDK08G65C5XTMA2 application, or IDK08G65C5XTMA2 equivalent, key selection criteria include its 650 V repetitive peak reverse voltage, temperature-independent switching behavior, low forward voltage (1.5–1.8 V @ 8 A, 25 °C), surge current capability (68 A @ 10 ms, 25 °C), and thermal resistance (1.2 K/W typical junction-to-case).
Technical Context
This SiC Schottky diode replaces conventional silicon fast recovery diodes in high-voltage, high-frequency power conversion stages. Its unipolar conduction eliminates minority-carrier storage, enabling zero reverse recovery loss and stable switching performance across -55 °C to 175 °C.
The device uses Infineon's 5th Generation thinQ!™ technology with diffusion-soldered die attachment and thin-wafer design, delivering improved figure-of-merit (Qc × Vf) and optimized thermal characteristics for co-packaging with 650 V CoolMOS™ MOSFETs in PFC and DC-DC topologies.
Key Specifications

FAQ
Is IDK08G65C5XTMA2 pin-compatible with standard TO-263-2 silicon diodes?
Yes - it uses the industry-standard PG-TO263-2 (D²PAK) footprint with identical pad layout and mounting dimensions. Pin 1 (tab) is cathode, Pin 2 is anode, and Pin 3 is non-connected. No PCB redesign is needed when upgrading from Si FRDs, though thermal and layout optimization for SiC's faster switching is recommended.
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, the device delivers full 8 A with Tj ≤ 175 °C using the typical RthJC of 1.2 K/W. Operation above 145 °C case temperature requires derating per Figure 7 in the datasheet, with zero current allowed at TC ≥ 175 °C.
Does IDK08G65C5XTMA2 require a gate resistor or snubber network?
No - as a Schottky diode, it has no gate terminal and requires no gate resistor. However, a small RC snubber (e.g., 10 Ω + 100 pF) across the diode may be used in ultra-fast switching circuits (>200 kHz) to damp parasitic ringing caused by layout inductance interacting with its low capacitance (32 pF @ 600 V).
Can IDK08G65C5XTMA2 be paralleled for higher current handling?
Yes - its positive temperature coefficient of forward voltage enables natural current sharing. Parallel operation requires matched layout symmetry, identical trace lengths, and shared thermal coupling (e.g., common copper pour). Derate total current by 15% for two devices and 25% for three or more to account for thermal and parametric mismatch.
