BST39TA Description

Short technical summary and product information.

The BST39TA from Diodes Incorporated is a 350V NPN high-voltage bipolar junction transistor designed for general purpose switching and amplification applications. It features a minimum collector-emitter breakdown voltage of 350V and a maximum continuous collector current of 0.5A, with a peak pulse current capability of 1A.

 

The transistor offers a DC current gain (hFE) of 40 minimum at 20mA collector current and 10V collector-emitter voltage, and a low saturation voltage of 500mV maximum at 4mA base current and 50mA collector current. The transition frequency is typically 70MHz, making it suitable for high-speed switching circuits.

 

The device is housed in a SOT89 surface-mount package (SOT-89-3 supplier package) with matte tin plated leads. It is fully RoHS3 compliant, lead-free, and halogen and antimony free. The operating junction temperature range is -55 to +150°C. Maximum power dissipation is 1W at 25°C ambient. Moisture sensitivity level is 1 per J-STD-020, allowing unlimited floor life.
