About this product
The TIP34 is a PNP power driving transistor in a TO-220 package, intended for higher-power driver and output stages. It is the complement of the TIP33 NPN device and is used in linear amplifiers, regulator pass stages and motor or load driving. Mount it on a heatsink for rated power operation.

Frequently asked questions
Can the TIP34 be used in a linear regulator pass stage?
Yes, it can be used as a series pass element in a linear regulator for higher currents, provided it is mounted on a suitable heatsink and the dissipation (voltage drop times current) stays within limits.
Which pin is the base on a TIP34?
In the TO-220 package the TIP34 is usually Base, Collector, Emitter from left to right with the front face toward you and leads pointing down. The tab is connected to the collector. Confirm on the datasheet before wiring.
