BAS19LT1 Description

Short technical summary and product information.

The BAS19LT1 is a high voltage switching diode manufactured by On Semiconductor. It features a maximum DC reverse voltage of 120V and an average rectified forward current of 200mA. The forward voltage is rated at 1.25V maximum at 200mA. With a reverse recovery time of 50ns, this diode is suitable for high-speed switching applications.

 

This device is housed in a compact SOT-23-3 (TO-236) surface mount package, making it ideal for space-constrained designs. The junction operating temperature range is -55°C to 150°C, and the maximum power dissipation is 385mW when mounted on an FR-5 board. The thermal resistance from junction to ambient is 556°C/W.

 

The BAS19LT1 is Pb-Free, Halogen Free/BFR Free, and RoHS compliant. It is designed for general purpose switching and signal processing circuits where high voltage capability and fast switching are required.
