Product details
Overview
IDW12G65C5XKSA1 from Infineon is a 650 V, 12 A silicon carbide Schottky diode in TO-247-3 package, featuring zero reverse recovery charge, 1.5–2.1 V forward voltage (12 A, 25–150°C), 18 nC capacitive charge at 400 V, and 175°C maximum junction temperature. It replaces silicon fast recovery diodes in high-frequency PFC stages of solar inverters and UPS systems.
For engineers reviewing the IDW12G65C5XKSA1 datasheet, IDW12G65C5XKSA1 pinout, IDW12G65C5XKSA1 application, or IDW12G65C5XKSA1 equivalent, key selection criteria include its SiC-specific thermal stability, absence of reverse recovery loss, 650 V blocking capability, surge current rating up to 71 A (10 ms), and compatibility with CoolMOS™ 650 V switching devices.
Technical Context
This 5th-generation thinQ!™ SiC Schottky diode uses ultra-thin wafer technology to reduce Qc × Vf figure of merit, enabling higher efficiency across full load range. Its unipolar conduction eliminates minority-carrier storage, resulting in temperature-independent switching behavior and no reverse recovery tail current.
The device is rated for 650 V repetitive peak reverse voltage (VRRM), supports 100 V/ns dv/dt ruggedness, and delivers 76 W power dissipation at TC = 25°C with RthJC ≤ 2.0 K/W. It is qualified per JEDEC standards for industrial and renewable energy applications.
Key Specifications

| IF (TC < 125°C) | 12 A - Continuous forward current rating usable in thermally constrained enclosures with active cooling |
| VF (12 A, 25°C) | 1.5–1.7 V - Low conduction loss enables >98% PFC stage efficiency at light-to-full load |
| Qc (VR = 400 V) | 18 nC - Minimal capacitive charge reduces turn-on switching loss in hard-switched topologies |
| Tj max | 175°C - Enables operation in high-ambient environments (e.g., rooftop solar inverters) without derating |
| RthJC | 1.5–2.0 K/W - Predictable thermal path allows accurate junction temperature estimation using case sensor |
| IR (650 V, 150°C) | 2.4–1350 µA - Low leakage preserves system standby efficiency and avoids thermal runaway in parallel strings |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | No connection | Electrically isolated terminal; used only for mechanical mounting and heat sinking |
| Pin 2 | Cathode | Main high-side output node; connects to switching node in boost PFC or inverter leg |
| Pin 3 | Anode | Main low-side return path; ties to DC bus negative or neutral point in split-rail designs |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C3D10065A (Wolfspeed) | Same 650 V/10 A rating but TO-247-2 package; VF = 1.8 V @ 10 A, 25°C; Qc = 15 nC | Lacks isolated tab (no Pin 1); lower IF rating limits use in 12 A continuous designs | Select when board layout requires 2-pin footprint and thermal interface uses soldered tab only |
| STPSC12065DLF (STMicroelectronics) | 650 V/12 A, TO-247-3, VF = 1.7 V @ 12 A, 25°C; Qc = 22 nC; RthJC = 2.2 K/W | Higher Qc increases switching loss in >50 kHz designs; slightly higher thermal resistance | Prefer where cost sensitivity outweighs 12% higher EC loss at 400 V and proven ST automotive qualification path |
Compared with C3D10065A and STPSC12065DLF, IDW12G65C5XKSA1 offers the lowest Qc × Vf figure of merit among 650 V/12 A SiC diodes, best-in-class thermal resistance, and integrated n.c. mounting pin for mechanically robust heatsink attachment in high-vibration environments.

FAQ
Is IDW12G65C5XKSA1 pin-compatible with standard TO-247-3 silicon diodes?
Yes - it uses the same PG-TO247-3 mechanical outline and mounting hole pattern as legacy silicon diodes. However, Pin 1 is n.c. (not internally connected), unlike many Si diodes where Pin 1 is anode or cathode. PCB layout must isolate Pin 1 from circuit nodes.
What is the maximum allowable case temperature for continuous 12 A operation?
The datasheet specifies IF = 12 A only for TC < 125°C. At TC = 125°C, junction temperature reaches 175°C (Tj = TC + Ptot × RthJC ≈ 125 + 42 × 1.75 ≈ 175°C), which is the absolute maximum. Derating is required above TC = 125°C.
Does IDW12G65C5XKSA1 require gate drive or external control signals?
No - it is a passive two-terminal device with no gate or control input. It conducts forward current when anode voltage exceeds cathode voltage by ≥ VF, and blocks reverse voltage up to 650 V. No driver circuitry or biasing is needed.
Can IDW12G65C5XKSA1 be paralleled for higher current capacity?
Yes - its positive temperature coefficient of VF (≈ +0.3 mV/°C) enables inherent current sharing. Use matched layout symmetry, identical thermal paths, and Kelvin-sense connections to minimize imbalance. Avoid mixing with Si diodes due to differing thermal coefficients.
