BJT Transistor / TO126 - 2SD882 D882 NPN Bipolar Junction Transistor

Type and Polarity:
The 2SD882 is an NPN (Negative-Positive-Negative) transistor. It conducts current when the base is driven positive concerning the emitter.

Package Type:
The transistor is typically available in a TO-126 package, which is a small, three-lead package with the collector, base, and emitter pins.

Collector-Base Voltage (Vcb):
The maximum voltage that can be applied between the collector and the base is a parameter called Vcb. For the 2SD882, this voltage is typically around 40 volts.

Collector-Emitter Voltage (Vce):
The maximum voltage that can be applied between the collector and the emitter is a parameter called Vce. The 2SD882 usually has a Vce rating of around 30 volts.

Collector Current (Ic):
This parameter represents the maximum current that can flow through the collector. The 2SD882 is often rated for collector currents in the range of a few amperes.

Hfe (Current Gain):
The current gain, or hfe, specifies the amplification capability of the transistor. The 2SD882 typically has an hfe ranging from 40 to 320.

Applications:
The 2SD882 can be used in various electronic circuits where NPN transistors are required. Common applications include audio amplifier stages, voltage regulators, and other signal amplification circuits. It is often used in conjunction with its complementary PNP transistor, the 2SB772, in push-pull amplifier configurations.
