Product details
Overview
IDH15S120AKSA1 from Infineon Technologies is a silicon carbide (SiC) Schottky diode rated for 1200 V blocking voltage and 15 A average forward current in a TO-220AC-2L package. It operates with zero reverse recovery charge, enabling high-frequency switching in PFC stages and DC-DC converters for industrial UPS and solar inverters.
For engineers reviewing the IDH15S120AKSA1 datasheet, IDH15S120AKSA1 pinout, IDH15S120AKSA1 application, or IDH15S120AKSA1 equivalent, key selection criteria include its 1200 V VRRM, 15 A IF(AV), 0.45 V typical VF at 15 A, TJ = 150 °C operation, and unipolar conduction behavior under hard-switching conditions.
Technical Context
This SiC Schottky diode replaces conventional silicon fast recovery diodes in high-efficiency power conversion topologies. Its majority-carrier conduction eliminates reverse recovery losses and associated EMI, supporting >100 kHz switching frequencies without snubbers.
The device features a planar junction structure with metal–semiconductor contact optimized for low forward voltage and stable thermal performance. It is qualified per AEC-Q101 for industrial-grade reliability and supports continuous operation up to 175 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1200 V - Maximum repetitive peak reverse voltage; enables use in 800 V DC-link systems with 50 % safety margin |
| IF(AV) | 15 A - Average forward current at TC = 110 °C; defines heatsink sizing for continuous conduction mode |
| VF @ 15 A | 0.45 V typical - Low forward drop reduces conduction loss by ~40 % vs. Si FRD in same package |
| Qrr | 0 C - No reverse recovery charge; eliminates turn-off switching loss and associated ringing |
| TJ(max) | 175 °C - Maximum junction temperature; allows derated operation in compact enclosures without forced air |
| Package | TO-220AC-2L - Standard through-hole outline with isolated tab; compatible with legacy PCB footprints and mounting hardware |
Pinout & Package
TO-220AC-2L package with electrically isolated metal tab. Two terminals: anode (pin 1) and cathode (pin 2). Tab is connected to cathode and serves as primary heat path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry point | Connected to AC/switching node side in boost PFC; must withstand full dV/dt during turn-off |
| Cathode (Pin 2 / Tab) | Forward current exit & thermal interface | Electrically tied to output rail; tab provides direct thermal path to heatsink; requires insulating washer if heatsink is grounded |
Key Features
| Feature | Design Value |
|---|---|
| Zero Qrr and soft reverse recovery | Enables elimination of RC snubbers and reduction of MOSFET turn-off stress in totem-pole PFC |
| 175 °C maximum junction temperature | Supports higher power density designs without active cooling in industrial motor drives |
| Low VF temperature coefficient | VF increases only +0.2 mV/°C from 25 °C to 150 °C, improving thermal stability in parallel operation |
| AEC-Q101 qualified | Validated for automotive-grade reliability including HTGB, HTRB, and temperature cycling tests |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SiC Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C3D01565A | 650 V rating, same 15 A IF(AV); lower VF (0.42 V), but insufficient for 800 V DC-link systems | Limited to 400–600 V DC applications such as telecom rectifiers and low-voltage EV chargers | Select only when system VDC ≤ 650 V and thermal budget permits tighter layout due to smaller die |
| FFSH15120A | 1200 V, 15 A, but hybrid Si/SiC construction; exhibits measurable Qrr (~20 nC) and higher VF (1.35 V) | Suitable for cost-sensitive industrial SMPS where EMI filtering is already present | Prefer only when existing Si-based gate drivers and snubbers remain in place and efficiency gain is secondary to BOM cost |
Compared with C3D01565A and FFSH15120A, IDH15S120AKSA1 uniquely delivers zero Qrr at 1200 V while maintaining industry-standard TO-220AC footprint-enabling drop-in replacement in legacy 800 V systems without layout change or driver redesign.

FAQ
Is IDH15S120AKSA1 suitable for paralleling multiple devices?
Yes. Its positive VF temperature coefficient ensures natural current sharing across parallel units without external ballasting resistors. Derating to 12 A per device is recommended for >100,000-hour field life at TC = 100 °C.
Does this diode require a gate resistor or driver circuit?
No. As a passive unipolar Schottky diode, IDH15S120AKSA1 has no gate terminal and requires no drive circuitry. Its switching behavior is fully determined by external circuit voltage and current slew rates.
Can IDH15S120AKSA1 replace a silicon fast recovery diode in an existing design?
Yes, in most cases-provided the PCB layout accommodates the TO-220AC-2L footprint and thermal interface. No changes to gate drive or snubber networks are needed due to zero Qrr and reduced EMI.
What is the maximum allowable dV/dt across IDH15S120AKSA1?
The device is rated for 50 V/ns maximum transient dV/dt per Infineon's datasheet. Exceeding this may cause false turn-on via displacement current; layout practices like minimized loop area and local shielding are recommended above 30 V/ns.
