The BAS21HT1G from onsemi is a high-voltage, high-speed switching diode designed for fast switching applications requiring high reverse-voltage capability. It supports a continuous reverse voltage and repetitive peak reverse voltage of up to 250V, with a maximum forward current of 200mA.
The BAS21HT1G features a maximum reverse recovery time of 50ns and a maximum diode capacitance of 5pF, making it suitable for fast signal-switching circuits. Maximum forward voltage is 1.0V at 100mA and 1.25V at 200mA, while its low reverse leakage helps support reliable high-voltage operation.
Housed in a compact SOD-323 surface-mount package, the BAS21HT1G is suitable for automated PCB assembly. The device is Pb-free, halogen-free/BFR-free and RoHS compliant, making it suitable for industrial control, power management, high-voltage signal switching and general-purpose high-speed switching circuits.
