Description
- Low forward voltage drop (~0.55V at 5A), reducing power loss.
- High current capability (5A average forward current).
- Fast switching for improved performance in high-frequency circuits.
- Surge protection with a peak forward surge current of 150A.
- Reverse voltage rating of 40V, suitable for low-voltage DC/DC converters, SMPS, and reverse polarity protection.
Packaged in a SMB (DO-214AA) surface-mount form, it’s compact and ideal for space-constrained designs. Common applications include power supplies, automotive systems, and solar inverters.
For detailed specs, refer to the datasheet from STMicroelectronics.
Equivalent
- SB540 (5A, 40V)
- SS54 (5A, 40V)
- SR540 (5A, 40V)
