The 1N4148WT-7 from Diodes Incorporated is a surface-mount fast switching diode designed for general-purpose small-signal switching applications. It combines fast switching performance, high conductance and a very compact SOD-523 package for space-constrained electronic designs.
The device is rated for an 80V reverse voltage and a 100V non-repetitive peak reverse voltage, with a 53V RMS reverse-voltage rating. Maximum continuous forward current is 250mA, while average rectified output current is 125mA. Non-repetitive peak forward surge current reaches 2A at 1µs and 1A at 100ms.
The 1N4148WT offers a maximum 4ns reverse-recovery time, measured at IF=IR=10mA, and a maximum total capacitance of only 2pF at 1MHz. These characteristics make it well suited for high-speed switching, signal routing, clamping and pulse-processing circuits.
Maximum forward voltage is specified at 0.715V at 1mA, 0.855V at 10mA, 1.0V at 50mA and 1.25V at 150mA. Minimum reverse breakdown voltage is 75V at 1µA, while maximum reverse leakage current is 1µA at 75V.
The 1N4148WT-7 is supplied in an ultra-compact SOD-523 surface-mount package. Maximum power dissipation is 150mW, and the operating and storage temperature range is -55°C to +150°C. The device is lead-free, RoHS compliant, halogen- and antimony-free, and the -7 ordering option is supplied in 3,000-piece tape-and-reel packaging.
