IDK06G65C5XTMA2 Overview
A Schottky diode is a unipolar semiconductor device whose conduction is governed by majority-carrier flow across a metal-semiconductor barrier rather than by minority-carrier injection and storage, as in a PN-junction rectifier. The silicon-carbide wide-bandgap material (Eg ≈ 3.26 eV versus Si's 1.12 eV) raises the breakdown field by an order of magnitude, allowing a thinner, higher-doped drift region that simultaneously reduces on-state loss and switching loss. Within the power-semiconductor taxonomy, this places SiC Schottky diodes at the high-efficiency frontier of discrete rectifiers, sitting between standard silicon rectifiers and SiC MOSFETs in performance and between diodes and MOSFETs in circuit function.
Key features include a typical forward voltage (VF) of approximately 1.5 V at 6 A and 25 °C, negligible reverse recovery charge (Qrr), a maximum junction temperature of 175 °C, and an avalanche-rated design. The D2PAK real2pin package offers a low thermal resistance path (junction-to-case) suitable for high-current surface-mount reflow assembly, and is pin-compatible with industry-standard D2PAK rectifier footprints.
Technically, the Generation 5 CoolSiC process integrates a merged-PIN Schottky (MPS) structure that suppresses bipolar turn-on at surge currents while keeping capacitive charge (QC) low. This yields clean, snap-free switching waveforms, reduced EMI, and the ability to operate at switching frequencies well above the practical limits of silicon ultrafast rectifiers. The device is also qualified for industrial-grade reliability.
Typical applications include totem-pole bridgeless PFC, server and telecom SMPS output rectification, photovoltaic string inverters, on-board EV chargers, and industrial motor drives. The combination of low conduction loss and zero reverse recovery makes it especially attractive in continuous-conduction-mode (CCM) PFC stages where Si ultrafast rectifiers dominate switching loss.
When designing with this part, ensure the heatsink or PCB copper area keeps the junction below 150 °C at worst-case forward current, since conduction loss scales linearly with duty cycle. Place the device close to the switching node to minimize parasitic loop inductance that can otherwise ring with the diode's junction capacitance.

Typical Applications
IDK06G65C5XTMA2 is suitable for 6 applications: Totem-Pole Bridgeless PFC, Server and Telecom SMPS Output Rectification, Photovoltaic String Inverters, On-Board EV Chargers (OBC), Industrial Motor Drives, Auxiliary Power Supplies in Welding and UPS.
Totem-Pole Bridgeless PFC
The IDK06G65C5XTMA2's 650 V VRRM and zero Qrr make it ideal for the slow-leg position of a continuous-conduction-mode totem-pole bridgeless PFC, replacing a silicon diode bridge to eliminate reverse-recovery loss on the grid-frequency leg. Its 6 A IF(AV) supports PFC stages up to approximately 1.5 kW at 230 V AC, and 175 °C Tj(max) tolerates the elevated thermal stress of a heatsink-less or shared-cooling design. The D2PAK real2pin package simplifies PCB layout with a standard rectifier footprint.
Recommended
Server and Telecom SMPS Output Rectification
Used as the high-side or low-side rectifier on the secondary side of a high-density 48 V-input telecom or server SMPS, the IDK06G65C5XTMA2's 650 V blocking voltage provides ample margin above the 400 V rectified bus, while its 6 A current handles multi-kilowatt power levels. The absence of reverse recovery loss enables switching frequencies above 200 kHz, shrinking magnetic and capacitive volume. Surface-mount D2PAK assembly supports high-throughput reflow manufacturing required by hyperscale data-center supply chains.
Recommended
Photovoltaic String Inverters
The IDK06G65C5XTMA2 fits photovoltaic string-inverter boost and DC-link stages where 600 V-class SiC diodes replace silicon ultrafast rectifiers to reduce switching loss and raise European efficiency weighted above 98%. The 6 A current supports single-string designs up to 2 kW, and 175 °C Tj(max) tolerates outdoor enclosure temperatures up to 70 °C with conservative derating. The D2PAK real2pin package is widely accepted by inverter ODM manufacturers for automated SMT lines.
Recommended
On-Board EV Chargers (OBC)
In a 6.6 kW to 11 kW on-board charger, the IDK06G65C5XTMA2 can serve in the PFC rectifier bridge or the LLC resonant-rectifier output stage, where its 650 V rating meets the rectified 400 V AC bus and its zero Qrr improves LLC secondary-rectifier efficiency at 150–300 kHz switching frequency. The 6 A current matches a single-channel secondary-rectifier leg, and AEC-Q-style reliability screening plus 175 °C Tj(max) align with automotive under-hood thermal requirements.
Recommended
Industrial Motor Drives
The IDK06G65C5XTMA2 functions as the brake-clamp or freewheeling rectifier in industrial variable-frequency drives (VFDs) controlling 400 V AC induction or permanent-magnet motors up to about 1.5 kW per phase leg. Its 650 V VRRM tolerates DC-bus overshoot during hard braking events, and zero Qrr prevents the bus-voltage ringing that would otherwise require snubbers. The D2PAK package supports high-density inverter modules where shared heatsinking is the norm.
Recommended
Auxiliary Power Supplies in Welding and UPS
The IDK06G65C5XTMA2 suits the auxiliary 24 V or 48 V SMPS inside welding machines and uninterruptible power supplies (UPS), where high common-mode voltage on the auxiliary transformer secondary demands a 650 V rectifier. Its 6 A rating comfortably supplies 200–300 W auxiliary rails, and surface-mount D2PAK assembly reduces manufacturing cost versus through-hole TO-247 alternatives. The wide temperature range supports outdoor cabinet installations.

Design Notes
Estimated: at 6 A continuous forward current with typical VF of 1.5 V, conduction loss is approximately 9 W. The PG-TO263-2 package's RthJC of approximately 0.8 °C/W (per Infineon TO-263 family datasheet) requires case temperature below 161 °C to keep Tj at the 175 °C maximum. In practice, design for Tj ≤ 150 °C (a 25 °C margin) by attaching the D2PAK tab to a copper pour of at least 1 in² (6 cm²) on the top layer plus thermal vias to an inner-plane heatsink. Forced-air cooling is recommended above 4 A continuous.
Place the IDK06G65C5XTMA2 as close to the switching node as possible to minimize the parasitic loop inductance formed by the cathode tab and the PCB trace to the adjacent MOSFET drain. The D2PAK tab is electrically live (cathode), so the heatsink or copper pour must be isolated or matched to the circuit's positive rail. Use a 1 oz copper layer minimum with thermal-via arrays of 0.3 mm drill, 1 mm pitch under the tab, and avoid silkscreen or soldermask openings that would reduce solder-joint reliability on the large tab.
Do not use the IDK06G65C5XTMA2 below its minimum specified reverse-blocking current — SiC Schottky diodes do not support steady reverse leakage current as a normal operating mode and may enter thermal runaway if forward-biased in reverse. Also, do not parallel multiple devices without matching thermal resistance, since the negative temperature coefficient of VF at high currents can cause current hogging above 100 °C junction temperature. Finally, verify that the surge current (IFSM) is not exceeded during inrush events such as capacitive-load turn-on or input-voltage transients.
