BAS21THR Description

Short technical summary and product information.

The BAS21THR is a high-voltage switching diode designed and manufactured by Nexperia USA Inc. It is rated for a maximum reverse voltage of 200V and a repetitive peak reverse voltage of 250V, with a forward current capability of 200mA. The diode offers a fast reverse recovery time of 50ns, making it suitable for high-speed switching applications.

 

This device is housed in a compact SOT23 (TO-236AB) surface-mount plastic package, measuring 2.9mm x 1.3mm x 1mm with a 1.9mm lead pitch. It supports an operating temperature range of -55°C to 175°C, enabling use in high-temperature environments. The diode's maximum forward voltage is 1.25V at 200mA, and its typical capacitance is 5pF at 0V.

 

The BAS21THR is ideal for general-purpose and high-speed switching circuits. Its small footprint and surface-mount design facilitate automated assembly in space-constrained PCB layouts.
