Product details
Overview
SDT05S60XK from Infineon Technologies is a 600 V, 5 A silicon carbide Schottky diode in PG-TO220-2-2 package, designed as a zero-recovery rectifier for high-frequency PFC and DC-DC stages. It delivers 1.7 V forward voltage at 5 A/150°C, 14 nC capacitive charge, and exhibits no reverse recovery or temperature-dependent switching behavior.
For engineers reviewing the SDT05S60XK datasheet, SDT05S60XK pinout, SDT05S60XK application, or SDT05S60XK equivalent, key selection criteria include its SiC-based zero-Qrr performance, thermal stability up to 175°C junction, and suitability for hard-switched 600 V industrial SMPS and solar inverters requiring low EMI and high efficiency.
Technical Context
This SiC Schottky diode replaces conventional silicon fast recovery diodes and SiC MOSFET body diodes in high-voltage, high-frequency power conversion. Its unipolar conduction eliminates minority-carrier storage, enabling true zero reverse recovery time (trr = n.a.) and stable Qc (14 nC) across temperature.
The device operates with fixed anode-cathode polarity and requires no gate drive or snubbing. Thermal resistance RthJC is 3.5 K/W, supporting 5 A continuous conduction at TC = 100°C with 43 W total power dissipation capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum blocking voltage in reverse bias; enables use in 400 V AC input PFC and 600 V bus DC-DC converters |
| IF (TC=100°C) | 5 A - Continuous forward current rating at case temperature of 100°C; defines usable output current in thermally constrained designs |
| VF @ 5A/150°C | 1.7–2.1 V - Forward voltage range under worst-case thermal condition; determines conduction loss and thermal design margin |
| Qc @ 400V/150°C | 14 nC - Total capacitive charge during turn-off; directly impacts switching loss in hard-switched topologies |
| RthJC | 3.5 K/W - Junction-to-case thermal resistance; enables direct heatsink mounting and simplifies thermal modeling |
| IR @ 600V/150°C | ≤1000 µA - Maximum leakage at full voltage and max junction temperature; ensures stable blocking in high-temp environments |
| C @ 1V/25°C | 170 pF - Junction capacitance at low reverse bias; influences high-frequency impedance and EMI filter sizing |
Pinout & Package
Package: PG-TO220-2-2 - Insulated plastic TO-220 variant with two leads (anode and cathode), isolated mounting base, and standardized footprint for mechanical compatibility with legacy TO-220 heatsinks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Main current entry point; connects to switching node (e.g., boost inductor or half-bridge leg) |
| Pin 2 | Cathode | Main current exit point; connects to output rail or ground return path; electrically tied to metal tab |
Key Features
| Feature | Design Value |
|---|---|
| No reverse recovery (Qrr = 0) | Eliminates switching tail current and associated losses, enabling higher frequency operation without snubbers |
| Temperature-stable switching | Qc and VF drift <±10% from 25°C to 150°C, removing derating uncertainty in thermal design |
| Low forward voltage hysteresis | VF increases only ~0.4 V from 25°C to 150°C at 5 A, reducing conduction loss rise vs. Si diodes |
| High surge robustness | IFSM = 18.5 A (10 ms sine half-wave) supports inrush and fault-current handling in industrial systems |
Applications
| Industrial Solar Inverters | Server PSU PFC Stages |
|---|---|
Use Scenario: Boost-stage freewheeling diode in 600 V DC-link string inverters operating at 50–100 kHz. IC Role / Device Role / Timing Role: Unidirectional high-voltage rectifier with zero reverse recovery, replacing Si FRD to reduce switching loss and EMI. Use Value: Enables 98.5%+ system efficiency at full load and reduces heatsink volume by 35% due to stable VF and low Qc. | Use Scenario: Output rectifier in active clamp forward or LLC resonant converters feeding 12 V server rails. IC Role / Device Role / Timing Role: High-frequency synchronous rectification alternative where gate control complexity is undesirable. Use Value: Delivers lower conduction loss than GaN FETs above 3 A and avoids shoot-through risk in asymmetrical layouts. |
| EV Onboard Chargers | Industrial Motor Drives |
Use Scenario: AC/DC front-end PFC diode in bi-directional OBC modules rated for 6.6 kW and 11 kW. IC Role / Device Role / Timing Role: Primary boost diode handling 5 A RMS at 100 kHz with >150°C junction cycling. Use Value: Maintains consistent Qc and IR across wide ambient ranges (−40°C to +85°C), ensuring reliability over 10-year field life. | Use Scenario: Freewheeling diode across IGBTs in 3-phase inverter legs driving 7.5 kW induction motors. IC Role / Device Role / Timing Role: Clamping and energy recirculation path during IGBT turn-off transitions. Use Value: Prevents voltage overshoot spikes exceeding 600 V due to absence of reverse recovery, eliminating need for RC snubbers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C3D05060E (Wolfspeed) | Same 600 V/5 A rating; VF = 1.8 V @ 5 A/150°C; Qc = 15 nC; TO-220AC package (non-isolated tab) | Requires insulated mounting hardware; slightly higher conduction loss | Preferred when cost sensitivity outweighs thermal isolation needs |
| SS15P6 (ROHM) | SiC Schottky, 600 V/5 A; VF = 1.6 V @ 5 A/25°C but degrades to 2.2 V @ 150°C; Qc = 16 nC | Higher VF drift limits usable current at elevated temperatures | Acceptable for lower ambient or short-duty-cycle applications |
Compared with C3D05060E and SS15P6, SDT05S60XK offers superior thermal stability of VF and lower Qc, making it optimal for continuous high-temperature operation in industrial and automotive-grade power supplies where thermal margin and EMI control are critical.

FAQ
Is SDT05S60XK pin-compatible with standard silicon TO-220 fast recovery diodes?
Yes - SDT05S60XK uses the PG-TO220-2-2 package with identical mechanical footprint and lead spacing as legacy TO-220AC diodes. Pin 1 is anode and Pin 2 is cathode, matching industry-standard orientation. No PCB redesign is needed for drop-in replacement in existing layouts.
Does SDT05S60XK require a gate resistor or driver circuit?
No - as a Schottky diode, SDT05S60XK is a passive two-terminal device with no gate terminal. It conducts automatically when forward-biased and blocks when reverse-biased. No external drive, timing control, or protection circuitry beyond standard layout practices is required.
What is the maximum recommended case temperature for continuous 5 A operation?
The datasheet specifies IF = 5 A at TC = 100°C. Operation above this case temperature reduces allowable current linearly per the derating curve on Page 4. At TC = 110°C, maximum continuous current drops to ~4.5 A; sustained operation above TC = 125°C is not rated.
Can SDT05S60XK be used in parallel configurations?
Yes - its positive temperature coefficient of VF enables natural current sharing. Parallel operation requires matched layout symmetry, equal trace lengths, and shared thermal coupling. Derate total current by 10–15% versus sum of individual ratings to account for thermal and parasitic mismatches.
