2N2905 Information

Description

The 2N2905 is a Bipolar Junction Transistor (BJT), specifically a PNP type. This transistor is designed for high voltage applications, with a maximum rating of 60 volts. It has a current gain of around 100 at low collector currents. The TO-205AD and TO-39-3 Metal Can packages provide thermal dissipation capabilities suitable for various circuit configurations. Overall, the 2N2905 is a versatile PNP transistor that finds applications in amplifiers, switches, and voltage regulators.

Features

The 2N2905 transistor is a PNP bipolar junction transistor (BJT). Its key features are:
High voltage rating: It can handle voltages up to 60V.
Current capability: The saturation collector current is approximately 600mA.
Package: TO-205AD or TO-39 Metal Can, suitable for through-hole mounting. These features make the 2N2905 suitable for applications like amplifiers, voltage control, and switch circuits.

Package

The 2N2905 transistor has two package types: TO-205AD (SOT-23) for surface mount, and TO-39-3 Metal Can for through-hole mounting.

Pinout

The 2N2905 is a PNP bipolar junction transistor (BJT). It doesn't have a specific pin count as it's a through-hole device with a single lead. Functionally, the lead serves as both the collector and emitter connections. The base is typically connected to a control circuit for controlling the current flowing through the transistor.

Manufacturer

The manufacturer of the 2N2905 transistor is Microchip Technology Inc. Microchip is a semiconductor company, known for developing integrated circuits (ICs) and other electronic components. Their focus lies in innovation and expanding their product offerings to various industries.

Applications

The 2N2905, a PNP bipolar transistor, finds applications in electronic circuits such as amplifiers, switching circuits, and voltage regulators. These uses rely on its ability to control current flow.

Equivalent

The equivalent products for the 2N2905 are other PNP bipolar transistors with similar specifications, such as BC847, 2SC5200, or 3AG11D.
