Pinout
Pin Functions (when viewing the flat side with pins down):
1. Emitter (E): Left pin – connected to the ground or lower voltage in circuits.
2. Base (B): Middle pin – controls the transistor's switching/amplification.
3. Collector (C): Right pin – connects to the load or higher voltage.
Key Features:
- PNP polarity (current flows from Emitter to Collector when Base is pulled low).
- Low power, general-purpose switching/amplification.
- Max ratings: 80V (VCEO), 500mA (IC).
Used in signal amplification, switching circuits, and driver applications.
Application
1. Switching Circuits – For load control in low-power applications.
2. Amplification – Small-signal amplification in audio and RF stages.
3. Signal Inversion – Logic level shifting in digital circuits.
4. Consumer Electronics – Found in devices like remote controls, LED drivers, and portable gadgets.
5. Automotive Systems – Used in sensors and low-power control modules.
Its compact SOT-23 package makes it suitable for space-constrained designs.
