Description:

The 2SB1453 is a power transistor that can directly drive from the IC output. This transistor is ideal for motor drivers and solenoid drivers in such as OA and FA equipment. In addition, a small resin-molded insulation type package contributes to high-density mounting and reduction of mounting cost.

A PNP transistor is one of the semiconductor components used in electrical engineering and electronic circuit design, belonging to the Bipolar Junction Transistor (BJT) family. The PNP transistor consists of three layers of semiconductor material: P-type, N-type, and P-type, each with different charges. The name PNP transistor stands for “Positive-Negative-Positive,” reflecting the characteristics of these three semiconductor layers.

PNP Configuration:

1. Emitter: The emitter is the first layer and is made of P-type semiconductor material. The emitter serves as the primary source of current.

2. Base: The base is the second layer and is made of N-type semiconductor material. The base controls the current between the emitter and collector.

3. Collector: The collector is the third layer and is made of P-type semiconductor material. The collector collects the current, which flows from the emitter through the base.

 

Features:

• High DC current amplifier ratio hFE ≥ 100 (VCE = −5 V, IC = −0.5 A)

• Mold package that does not require an insulating board or insulation bushing
