Product details
Overview
IDT16S60CHKSA1 from Infineon Technologies is a 600 V, 16 A Schottky rectifier diode in TO-220AC package with low forward voltage (VF = 1.85 V @ 16 A), fast recovery time (trr < 50 ns), and junction temperature rating up to 175 °C. It serves as a high-efficiency output rectifier in industrial SMPS and PFC stages.
For engineers reviewing the IDT16S60CHKSA1 datasheet, IDT16S60CHKSA1 pinout, IDT16S60CHKSA1 application, or IDT16S60CHKSA1 equivalent, key selection criteria include VF vs. temperature stability, soft reverse recovery behavior, surge current capability (IFSM = 140 A), and thermal resistance (RthJC = 1.2 K/W).
Technical Context
This Schottky diode employs a silicon carbide (SiC)-enhanced planar junction structure optimized for high-voltage operation beyond conventional Schottky limits. Its design integrates a guard ring and field plate to suppress edge breakdown at 600 V blocking, enabling stable unidirectional conduction without minority-carrier storage delay.
Unlike standard Si Schottkys, it maintains low leakage (IR = 100 µA @ 600 V, TJ = 150 °C) while delivering VF < 1.9 V across -40 °C to +175 °C, supporting high-frequency switching (>100 kHz) in continuous conduction mode (CCM) PFC converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse voltage; defines safe operating limit in boost PFC and flyback snubber circuits. |
| IF(AV) | 16 A - Average forward current at TC = 110 °C; supports sustained 500 W–1 kW power stage output rectification. |
| VF @ IF = 16 A | 1.85 V - Forward voltage drop; directly determines conduction loss (29.6 W) and thermal load in high-current paths. |
| trr | < 50 ns - Reverse recovery time; enables clean turn-off with minimal switching loss and EMI in hard-switched topologies. |
| RthJC | 1.2 K/W - Junction-to-case thermal resistance; allows direct mounting to heatsink for reliable 175 °C junction operation. |
| IFSM | 140 A - Non-repetitive peak forward surge current; withstands inrush and overload transients in industrial AC/DC supplies. |
Pinout & Package
TO-220AC package with isolated tab; single-diode configuration featuring anode and cathode terminals only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Input current entry point | Connected to transformer secondary or switch node; must handle full load current and transient surges. |
| Cathode (Pin 2) | Output current exit point | Routes rectified DC to bulk capacitor; requires low-inductance layout to minimize voltage spikes. |
| Tab (Metal surface) | Thermal path / Electrical isolation | Electrically isolated from die; used for mechanical mounting and heat dissipation to heatsink. |
Key Features
| Feature | Design Value |
|---|---|
| 600 V blocking capability | Enables use in 400 V DC bus systems with 50 % voltage margin for line surges and ringing. |
| Soft reverse recovery | Reduces EMI generation during turn-off, easing compliance with CISPR-22 Class B conducted emissions limits. |
| 175 °C maximum junction temperature | Supports operation in sealed enclosures or high-ambient environments without derating. |
| Low thermal resistance (1.2 K/W) | Permits compact heatsink design and eliminates need for forced air cooling in 1 kW designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1606D | 600 V, 16 A fast recovery diode (not Schottky); VF = 2.2 V @ 16 A, trr = 65 ns | Higher conduction loss (+5.6 W), higher EMI due to minority carrier tail | Preferred where cost sensitivity outweighs efficiency targets and thermal constraints allow higher VF. |
| Vishay VS-16EWH06FN-M3 | 600 V, 16 A SiC Schottky; VF = 1.7 V @ 16 A, RthJC = 1.0 K/W, but requires gate drive isolation for parallel use | Lower VF improves efficiency further but demands careful layout to avoid parasitic oscillation | Recommended for new designs targeting >94 % efficiency and space-constrained thermal management. |
Compared with STTH1606D, IDT16S60CHKSA1 reduces conduction loss and EMI; versus VS-16EWH06FN-M3, it trades 0.15 V lower VF for simpler layout and proven robustness in legacy industrial PCBs.

FAQ
Is IDT16S60CHKSA1 a silicon carbide (SiC) diode?
No. IDT16S60CHKSA1 is a silicon-based Schottky diode with proprietary field-stop and guard-ring enhancements enabling 600 V operation. It does not use SiC material; its structure remains monolithic silicon with optimized planar junction design.
Can IDT16S60CHKSA1 replace standard 600 V fast recovery diodes in existing designs?
Yes-provided layout accommodates lower VF-induced current sharing imbalance and reduced reverse recovery noise. No gate drive or snubber redesign is needed, but EMI filtering may require minor adjustment due to absence of recovery tail.
What is the maximum allowable case temperature for continuous operation?
The maximum case temperature is 110 °C at rated 16 A average current. At higher currents or ambient temperatures, derating per the datasheet thermal curves is required to maintain TJ ≤ 175 °C.
Does IDT16S60CHKSA1 meet automotive qualification standards?
IDT16S60CHKSA1 is not AEC-Q101 qualified. It meets industrial-grade reliability standards (JESD22-A108) and is widely used in automotive OBCs as a de facto solution, but formal automotive qualification requires additional testing and documentation.
