The US1DFA is a super fast surface mount rectifier diode designed and manufactured by On Semiconductor. This device is part of the US1AFA-US1MFA series, offering a repetitive peak reverse voltage of 200V and an average forward rectified current of 1A. Its fast reverse recovery time of only 50ns makes it suitable for high-frequency switching applications.
Key electrical characteristics include a forward voltage of 0.95V at 1A, a low reverse leakage current of 5 µA at 25°C, and a high surge current capability of 30A. The device operates over a junction temperature range of -55°C to +150°C, ensuring reliable performance in demanding environments.
The US1DFA is housed in the compact SOD-123FL surface mount package, with a supplier device package designation of SOD-123FA. It is lead-free, halogen-free, and RoHS compliant, and meets MSL 1 moisture sensitivity level per J-STD-020. The automotive-grade variant NRVUS1DFA is also available, qualified to AEC-Q101.
Typical applications include power supplies, inverters, and freewheeling diodes in switching circuits. The SOD-123FA package enables efficient thermal management with a junction-to-lead thermal resistance of 21°C/W and junction-to-ambient of 153°C/W when mounted on minimum pad.
