TIP29A-BP

A TIP29A-BP transistor is a single component from a family of medium power, silicon NPN transistors commonly used in a wide range of applications. The TIP29A-BP supersedes the TIP29, and has higher power ratings, making it a suitable component for high-current, high-voltage applications. It is available in both to-220 and to-220F packages, meaning it can be placed in both vertical and horizontal mounting arrangements.

Features and Benefits

The TIP29A-BP offers several advantages when used in a variety of applications. Its high current rating of 5A, high voltage rating of 100V, and a gain of at least 2000 makes it suitable for a variety of applications. Additionally, the TIP29A-BP is provided with a built-in heatsink. This heatsink allows for quicker warm-up time during the initial startup and helps disperse the heat generated by the component, delivering greater performance and stability. Furthermore, it’s small size makes it an ideal component for space-constrained designs.

Applications

The TIP29A-BP can be used in several applications, including industrial control systems, power supplies, amplifiers, voltage regulators, and LED drivers. It is also commonly used as a relay switch, driving high-current loads with a low-voltage afferent. The TIP29A-BP is an excellent choice for any application requiring high current and high voltage handling, such as automotive applications, high-power amplifiers, power-switching circuits, motor control, and more.

Working Principle

The TIP29A-BP is a PNP-type transistor, meaning that it consists of three terminals – the emitter, the base, and the collector. The TIP29A-BP utilizes a standard NPN configuration, with the emitter at a higher voltage potential than the base, and the collector at a higher voltage potential than the emitter.

In typical applications such as a relay switch, the TIP29A-BP will be voltage driven. This means that the voltage supplied to the base will act as a gate or switch, affecting the flow of current from the emitter to the collector. When the voltage applied to the base is lower than the voltage supplied to the emitter, the TIP29A-BP will be in its “off” state and current will not flow from the emitter to the collector. In contrast, when the voltage applied to the base is higher than the voltage supplied to the emitter, the TIP29A-BP will be in its “on” state and current will flow.

Conclusion

The TIP29A-BP is an extremely versatile and reliable single-component transistor designed for use in high-power, high-current applications. Featuring a high current rating, high voltage rating, and a built-in heatsink, the TIP29A-BP is an ideal choice for a wide range of applications, such as automotive, power supplies, amplifiers, and more.
