BU931T Information
BU931T by STMicroelectronics is a Power Bipolar Transistor.
Power Bipolar Transistors are under the broader part category of Transistors.
A transistor is a small semiconductor device used to amplify, control, or create electrical signals. When selecting a transistor, factors such as voltage, current rating, gain, and power dissipation must be considered, with common types.

This table gives cross-reference parts and alternative options found for BU931T. The Form Fit Function (FFF) tab will give you the options that are more likely to serve as direct pin-to-pin alternates or drop-in parts. The Functional Equivalents tab will give you options that are likely to match the same function of BU931T, but it may not fit your design. Always verify details of parts you are evaluating, as these parts are offered as suggestions for what you are looking for and are not guaranteed.
The recommended operating voltage range for the BU931T is 2.7V to 5.5V, with a typical voltage of 3.3V.
To ensure proper power-on and power-off, it's recommended to use a power-on reset (POR) circuit and a voltage supervisor to monitor the power supply voltage.
The maximum current rating for the BU931T's output pins is 20mA per pin, with a total current limit of 100mA for all output pins combined.
To ensure ESD protection, it's recommended to use a TVS (Transient Voltage Suppressor) diode or a dedicated ESD protection IC, such as the STMicroelectronics ESDAxx series, in conjunction with the BU931T.
For optimal performance, it's recommended to follow a star-topology layout, with the BU931T at the center, and to use short, direct traces for the power supply and output pins.
