The Diodes Incorporated 1N4148WS-7-F is a compact surface-mount fast switching diode designed for general-purpose high-speed switching, signal processing, logic, and protection applications. It is supplied in a small SOD-323 package, making it suitable for high-density PCB layouts and space-constrained electronic designs.
The device features a 75V peak repetitive reverse voltage (VRRM) and 75V DC blocking voltage, with a non-repetitive peak reverse voltage of 100V. It supports up to 300mA continuous forward current and 150mA average rectified output current. Its maximum reverse recovery time is only 4ns, while total capacitance is limited to 2.0pF, enabling fast switching performance in small-signal circuits.
Maximum forward voltage is 0.715V at 1mA, 0.855V at 10mA, and 1.25V at 150mA under the specified test conditions. Maximum power dissipation is 200mW, and the operating and storage junction temperature range extends from -55°C to +150°C.
The 1N4148WS-7-F uses a lead-free, RoHS-compliant SOD-323 package with typical dimensions of approximately 2.50 × 1.70 × 1.05mm. The -7-F ordering suffix specifies tape-and-reel packaging with 3,000 devices per reel. For automotive applications requiring AEC-Q101 qualification, Diodes Incorporated identifies the separate 1N4148WSQ version rather than the standard 1N4148WS-7-F.
