BUV298AV is an NPN alloy junction medium power transistor with an effective guaranteed current gain of 100. It has an epitaxial base structure and integrated gate open collector and a collector current rating of up to 10 items. It is designed for use as an amplifier and driver for audio, switching, and power supply applications.

BUV298AV is a kind of single bipolar (BJT) transistor with Isolated Gate Open Collector (IGOC). It is a three-layer device, including collector, base and emitter. It can withstand not more than -55℃ ~ 150℃ junction temperature. Its long-term packages are specified as TO-127 (Tabless Isolated Package) and TO-252 (Dual Inline Package). The structure belongs to BUV 298AV is shown as follows.

Working Principle of BUV298AV

When no electrical signal is applied to the base of a transistor, the collector terminal does not allow current to flow through it. This is the normal state of a transistor, it is functioning as a switch, staying open and not allowing current to pass between its collector and emitter side. However, when a small electrical signal is applied to the base of the transistor, it begins to allow current to flow through between the collector and emitter side.

The signal applied to the base will "turn on" the transistor and allow current flow. The signal at the base can be a direct current (DC) level or the transistor can be used to amplify alternating current (AC) signals. Current will flow through the transistor (assuming the base circuit is functional) until the signal at the base is removed. Once removed, the collector will again not allow current to pass between the collector and emitter side.

The BUV298AV transistor has a base-emitter voltage of 0.7V or less. Its collector-emitter saturation voltage is less than VCE1. The collector-base breakdown voltage of the transistor is at least 1.1V. The current gain of the transistor is guaranteed to be at least 100. The transistor has a large current capacity and is designed for use in audio, switching and power supply applications.
