The BUL310 is a high voltage fast-switching NPN power transistor manufactured by STMicroelectronics using Multi Epitaxial Planar technology. It is designed for applications such as electronic ballasts for fluorescent lighting and low cost switch-mode power supplies.
Key electrical specifications include a collector-emitter voltage (VCEO) of 500V and a collector-emitter sustaining voltage of 500V minimum. The continuous collector current is rated at 5A, with a peak current capability of 10A. The DC current gain (hFE) is a minimum of 6 at 3A collector current and 2.5V VCE, and a minimum of 10 at 10mA and 5V VCE. The collector-emitter saturation voltage is typically 0.7V at 3A and 600mA base current, with a maximum of 1.1V.
Switching characteristics include a typical storage time of 1.2µs and a typical fall time of 80ns, making the device suitable for high-frequency operation. The maximum power dissipation is 75W at a case temperature of 25°C. The junction-to-case thermal resistance is 1.65°C/W, and the junction-to-ambient thermal resistance is 62.5°C/W. The device is housed in a TO-220 through-hole package with three leads.
This product is marked as obsolete by the manufacturer. It is RoHS3 compliant (unverified) and has an MSL of 1 (unlimited floor life). The BUL310 is suitable for use in lighting ballasts and single-transistor converters where high voltage and fast switching are required.
