BD136 PNP Transistor -45V -1.5A

The BD136 designed as a small single NPN Transistor manufactured in TO-126 metal can package. The BD136 comes as a low signal PNP Complementary to BD135, BD137 and BD139 respectively known for its low noise operations making it famously used in signal processing circuits and television receivers. BD136 defined as a semiconductor device used to amplify or switch electronic signals and electrical power. This semiconductor material has at least three terminals for external circuit connection. The current through another pair of terminals is controlled by a voltage or current provided to one pair of transistor terminals. A transistor can magnify a signal because the regulated (output) power can be higher than the controlling (input) power.

Transistors are the most important component in electronic circuits. A PNP transistor is made up of two pieces of N-type silicon (the base) sandwiched between two pieces of P-type silicon (collector and emitter). These transistors were created with the sole purpose of passing holes from the emitter to the collector (so conventional current flows from collector to emitter).

The function of the PNP transistor is to amplify weak signals as they reach the base and create powerful amplified signals at the collector end. The migration of holes in a PNP transistor is from the emitter to the collector area, causing current to flow through the transistor. Because the bulk of charge carriers in such transistors are holes, they are commonly employed in circuits. As a result, compared to electrones, it has a high mobility.
