Product details
Overview
IDT04S60CHKSA1 from Infineon Technologies is a 600 V, 4 A Schottky rectifier diode in TO-220AC package with low forward voltage (VF = 1.75 V @ 4 A) and fast reverse recovery (trr < 50 ns), designed for high-efficiency AC/DC PFC stages and offline SMPS primary-side freewheeling.
For engineers reviewing the IDT04S60CHKSA1 datasheet, IDT04S60CHKSA1 pinout, IDT04S60CHKSA1 application, or IDT04S60CHKSA1 equivalent, key selection criteria include VF vs. temperature stability, soft-recovery behavior under hard-switching, junction-to-case thermal resistance, and TO-220AC mounting compatibility with standard heatsinks.
Technical Context
This Schottky diode employs platinum-silicide (PtSi) barrier technology to achieve stable 600 V blocking capability while maintaining low conduction loss. Its unipolar conduction mechanism eliminates minority-carrier storage, enabling inherently fast switching without tail current.
The device features a single-diode configuration with cathode-connected tab (TO-220AC), optimized for high-current freewheeling paths where low VF and minimal switching loss are critical. Junction-to-case thermal resistance is specified at 2.5 K/W, supporting continuous 4 A operation with adequate heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VRRM) | 600 V - supports universal-input offline SMPS designs up to 400 V DC bus with safety margin. |
| Forward Current (IF(AV)) | 4 A - rated average forward current at case temperature of 130 °C, suitable for compact PFC boost diodes. |
| Forward Voltage (VF) | 1.75 V @ 4 A, 150 °C - enables lower conduction loss than Si PiN diodes in high-frequency PFC stages. |
| Reverse Recovery Time (trr) | < 50 ns - eliminates reverse recovery loss, critical for >100 kHz hard-switched topologies. |
| Junction-to-Case RθJC | 2.5 K/W - allows direct mounting to heatsink for thermal management in space-constrained power supplies. |
| Operating Junction Temp | -65 °C to +175 °C - supports extended ambient operation in industrial and telecom power systems. |
Pinout & Package
Package: TO-220AC (2-pin, isolated tab). Cathode connected to metal tab; anode on lead 1. Tab is electrically active and must be insulated if mounted to grounded heatsink.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Current entry point during forward conduction | Connected to switch node (e.g., MOSFET drain) in boost PFC; requires low-inductance layout. |
| Cathode (Tab) | Current exit point; electrically tied to metal case | Must be thermally coupled to heatsink and electrically isolated from chassis ground unless system design permits common-cathode reference. |
Key Features
| Feature | Design Value |
|---|---|
| Soft reverse recovery | Minimizes EMI generation and voltage overshoot during turn-off in hard-switched converters. |
| Low VF temperature coefficient | VF increases only ~0.3 mV/°C - maintains efficiency across wide operating temperature range. |
| High surge current rating (IFSM) | 120 A peak - withstands inrush and transient overloads in AC input rectification stages. |
| Qualified per AEC-Q101 | Validated for automotive-grade reliability including HTGB, HTRB, and temperature cycling. |
Applications
| Server PSU PFC Stage | Industrial AC/DC Adapter |
|---|---|

IC Role / Device Role / Timing Role: High-voltage leg diode in active bridge configuration; handles 4 A RMS at 600 V blocking. Use Value: AEC-Q101 qualification ensures robustness against automotive load dumps and thermal cycling in vehicle-mounted charging systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-4EY60-M3 | Same 600 V/4 A rating but VF = 1.85 V @ 4 A; TO-220AC package with non-isolated tab. | Lacks AEC-Q101 qualification; not recommended for automotive OBC or harsh-environment industrial use. | Select when cost sensitivity outweighs automotive qualification and VF margin is acceptable. |
| ON Semiconductor MUR460E | 600 V/4 A ultrafast PiN diode (trr = 60 ns); higher VF (2.2 V) but higher surge rating (150 A). | Better surge robustness but introduces reverse recovery loss; suited for lower-frequency (<60 kHz) or cost-sensitive consumer adapters. | Prefer where EMI constraints are relaxed and thermal margin exists for higher conduction loss. |
Compared with VS-4EY60-M3 and MUR460E, IDT04S60CHKSA1 delivers the lowest VF among 600 V Schottkys while maintaining automotive-grade reliability-making it optimal for high-density, high-efficiency PFC and EV charging applications where thermal and EMI margins are tight.

FAQ
Is IDT04S60CHKSA1 a silicon carbide (SiC) device?
No. IDT04S60CHKSA1 is a silicon-based Schottky diode using platinum-silicide barrier technology. It is not a SiC device-Infineon's SiC Schottky diodes carry "CoolSiC" branding and part numbers beginning with "IDH" or "IDS". This part delivers 600 V capability in silicon via advanced metallization and processing.
Can IDT04S60CHKSA1 replace a standard PiN rectifier in an existing 600 V design?
Yes, provided layout and thermal design accommodate its lower VF and faster switching. Unlike PiN diodes, it exhibits no reverse recovery charge-so snubber networks may be reduced or removed. Verify voltage overshoot and EMI behavior during prototype validation, especially in hard-switched topologies.
What is the maximum recommended case temperature for continuous operation?
The datasheet specifies IF(AV) = 4 A at TC = 130 °C. Derating begins above this point; maximum allowable case temperature is 175 °C (junction limit), but sustained operation above 130 °C requires derated current or enhanced heatsinking per the thermal curve in Infineon's datasheet Rev. 2.1.
Does the TO-220AC package have an electrically isolated tab?
No. The TO-220AC package has a conductive metal tab directly connected to the cathode. Electrical isolation from the heatsink is mandatory unless the cathode node is referenced to chassis ground. Use insulating pads or shoulder washers with appropriate dielectric rating (≥1 kV) for safe mounting.
