1N4148WS Description

Short technical summary and product information.

The 1N4148WS is a small signal switching diode manufactured by MDD, designed for high-speed switching applications. With a repetitive peak reverse voltage (VRRM) of 100V and a maximum average forward current (IF(AV)) of 150mA, it provides reliable performance in signal processing and clamping circuits. The diode features a reverse recovery time (trr) of less than 4ns and a low junction capacitance of 4pF at 0V and 1MHz, making it suitable for high-frequency designs. The forward voltage drop is 1V maximum at 10mA, ensuring efficient low-voltage operation. It can handle a peak forward surge current (IFSM) of 1A for up to 1µs, offering robustness against transients. Operating over a temperature range of -55°C to 150°C with a maximum power dissipation of 200mW, the device is packaged in the industry-standard SOD-323 (SC-76) surface mount package. The components are supplied in tape and reel packaging with 3000 pieces per reel, enabling automated assembly. The diode meets RoHS and REACH compliance requirements and has an MSL rating of 1 for unlimited moisture sensitivity.
