BSP19AT1 Description

Short technical summary and product information.

The BSP19AT1 is an NPN silicon epitaxial transistor designed for general purpose amplifier and switching applications. It is capable of handling collector-emitter voltages up to 350V (open base) and collector currents up to 100mA DC. The device is manufactured by On Semiconductor and is housed in the SOT-223 surface mount package, which is designed for medium power surface mount applications and allows for improved thermal conduction and visual inspection of soldered joints.

 

Key electrical characteristics include a collector-base voltage rating of 400V, emitter-base voltage of 5V, and low leakage currents (ICBO max 20nA, IEBO max 10nA). The total power dissipation is 0.8W at 25°C ambient, with a junction-to-ambient thermal resistance of 156°C/W. The device operates over a junction and storage temperature range of -65°C to +150°C, and is rated for ESD HBM Class 3B and MM Class C.

 

The BSP19AT1 is available in tape and reel packaging with a standard quantity of 1000 pieces per reel. The PNP complement is BSP16T1G. The device is RoHS compliant, Pb-free, and halogen free/BFR free. It is suitable for use in various high voltage applications where surface mount assembly is required.
