Taiwan Semiconductor has introduced a new line of 1200V wide bandgap SiC Schottky diodes, engineered for high-efficiency switching and long-term reliability in power systems operating at high frequency and temperature. Built on a merged PIN Schottky (MPS) structure, these devices combine fast switching characteristics with enhanced surge handling, thermal stability, and low leakage.
The series includes current ratings from 1A to 40A, offered in SOD-128, SMB, TO-252, TO-263, TO-220, and TO-247 packages. All models are AEC-Q101 qualified and rated for junction temperatures up to 175°C, making them suitable for use in EV fast charging, telecom infrastructure, energy storage systems, and industrial power supplies.
The MPS architecture enables the diode to handle high forward surge currents while maintaining a low forward voltage drop. This hybrid structure also suppresses reverse recovery losses, a key advantage in circuits switching at 100 kHz or above.
The series supports positive temperature coefficients on VF, helping simplify thermal management by providing predictable behaviour under rising load and temperature. With low capacitive charge and low leakage current, these diodes can significantly reduce power losses and improve stability across the full operating range.
Compact packages like SOD-128 and SMB offer creepage distances of 3.2mm and 2.6mm, respectively, supporting isolation in high-voltage designs with limited board space. Higher current models, including the TO-247-3L 40A variant, are designed for use in power conversion systems where thermal margin, creepage, and surge capability are critical.
Several packages also support Kelvin-source configurations to improve switching control in high-speed gate drive applications.
This diode family is designed for a wide range of power-critical systems, including:
PFC stages and high-frequency rectification
EV charging infrastructure and wall-mounted systems
Grid-connected energy storage converters
UPS systems and industrial backup power
PV microinverters and hybrid solar systems
Telecom DC-DC rectifiers
Bootstrap and desaturation diode roles in gate driver designs
All products are RoHS compliant, halogen-free, and built to support long-term field reliability in both commercial and automotive-grade environments.
