2SB861 datasheet

This transistor has three pins: emitter, base, and collector.

Description:

This is Silicon PNP Triple Diffused Transistor. It is commonly used in audio amplifier circuits, voltage regulators, and switching circuits. It can also be used in other general-purpose applications where a PNP transistor is required.

Advantages Vs Disadvantages

Advantages:

1. High voltage and current handling capabilities

2. Low saturation voltage, which reduces power dissipation and improves efficiency in switching applications

Disadvantages:

1. Limited maximum current rating, which makes it unsuitable for high power applications

2. Relatively low maximum frequency rating, which makes it unsuitable for high-speed applications

3. Limited gain bandwidth product, which limits its use in high-frequency amplification circuits

Absolute maximum ratings ( Ta=25°C )

1. Collector to Base Voltage: Vcbo = -200 V
2. Collector to Emitter Voltage: Vceo = -150 V
3. Emitter to Base Voltage: Vebo = -6 V
4. Collector Current: Ic = -2 A
5. Total Dissipation : Pc =1.8 W
6. Junction Temperature: Tj = 150°C
7. Storage Temperature: Tsg = -55 ~ +150°C

Applications:

1. Low frequency power amplifier color TV vertical deflection output complementary pair with 2SD1138
