1. General description

PNP low VCEsat transistor in a small SOT23 (TO-236AB) Surface-Mounted Device (SMD) plastic

package.

NPN complement: PBSS4320T

2. Features and benefits

• Low collector-emitter saturation voltage VCEsat and corresponding low RCEsat

• High collector current capability

• High collector current gain

• Improved efficiency due to reduced heat generation

3. Applications

• Power management applications

• Low and medium power DC/DC convertors

• Supply line switching

• Battery chargers

• Linear voltage regulation with low voltage drop-out (LDO)
