BAS21LT3G Description

Short technical summary and product information.

The BAS21LT3G is a high voltage switching diode from On Semiconductor, designed for general-purpose switching applications requiring high reverse voltage capability. It features a maximum continuous reverse voltage of 250V and a repetitive peak reverse voltage of 250V, with a continuous forward current of 200mA and a peak surge current of 2A.

 

Electrical characteristics include a forward voltage of 1.25V maximum at 200mA, a reverse recovery time of 50ns, and low capacitance of 5pF at 0V and 1MHz. The device is housed in a surface-mount SOT-23-3 package (also known as TO-236), making it suitable for compact PCB layouts. Power dissipation is 385mW when mounted on an FR-5 board.

 

Additional features include ESD ratings of <500V HBM and <400V MM, and a wide operating temperature range of -55°C to +150°C. The diode is Pb-Free, Halogen Free/BFR Free, and RoHS compliant, ensuring environmental compatibility.
