BU931T is a high-voltage NPN Darlington transistor manufactured by STMicroelectronics. It is designed for switching and amplification applications requiring high current and voltage capability. The transistor features a collector-emitter breakdown voltage of 400V and a maximum collector current of 10A.
With a power dissipation of 125W and a minimum DC current gain (hFE) of 300 at 5A collector current, the BU931T provides efficient current amplification. The saturation voltage is 1.8V at 250mA base current and 10A collector current, making it suitable for low-voltage drop switching.
The device is housed in a standard TO-220-3 package with through-hole mounting. The junction temperature range extends up to 175°C, allowing robust operation in high-temperature environments.
Typical applications include motor control, power supply circuits, and high-voltage switching. The Darlington configuration simplifies drive requirements by requiring low base current to switch high collector loads.
