Can SMF5.0A be used in battery charging circuits for Li-Ion / Li-Po batteries?

Time：2026-07-22 Views：15次
Share：

Yes. The SMF5.0A is commonly deployed on the charging input line (5V USB or AC adapter output) of Li-Ion and Li-Po battery-powered devices. Its low reverse leakage characteristic (typically 50-150µA at actual battery voltage) helps preserve battery charge during long standby periods. The SMF5.0A protects the charging IC and battery management circuitry from ESD events during charger connection and disconnection.
