- High surge current resistance
ROHM’s 3rd generation SiC SBDs adopt a JBS (Junction Barrier Schottky) structure that provides higher surge current resistance with excellent leakage characteristics.
- Industry’s lowest forward voltage ([email protected]°C, [email protected]°C)
- Low current leakage
Generally, as forward voltage is reduced reverse current leakage increases. However, ROHM’s JBS structure minimizes leakage current along with forward voltage characteristics, resulting in 20x less leakage compared to 2nd Generation SiC SBDs at the same rated voltage (650V、Tj=150℃).
ROHM’s 3rd Generation SiC SBDs are currently available in the TO-220ACP package. A surface mount type (TO-263AB) is scheduled for future release based on market demands.
Power supply PFC circuits for PCs, servers, AC, and more.
- PFC (Power Factor Correction) Circuit
A circuit that suppresses peak current in order to limit the harmonic current generated within the power supply, contributing to greater energy savings.
- Forward Voltage (VF)
Refers to the voltage drop that occurs when current flows from positive to negative. The lower the value the greater the efficiency.
- Surge Resistance
The capability of protecting against current that momentarily exceeds steady state (i.e. in power supply circuits due to lightning).
