BC636 Transistor Datasheet [45 V 1 Amp PNP Transistor]

Last Updated on May 17, 2026 by Swagatam 3 Comments

The BC636 is a PNP bipolar junction transistor (BJT) that is specifically designed for low noise amplifier and switching applications. Here's the complete datasheet of the transistor BC636.

Pinout Configuration

BC636 pinout diagram

Referring the pinout diagram above, the BC636 transistor 3 pinouts.

  • Pin#1 = Emitter
  • Pin#2 = Base
  • Pin#3 = Collector

Electrical Characteristics:

  • Collector-Emitter Voltage (VCEO): 45V
  • Collector-Base Voltage (VCBO): 60V
  • Emitter-Base Voltage (VEBO): 5V
  • Collector Current (IC): 1A
  • Power Dissipation (PD): 625mW
  • DC Current Gain (hFE): 100-630
  • Transition Frequency (fT): 150MHz
  • Noise Figure (NF): 4dB

Package Details:

  • The BC636 transistor is available in a TO-92 package, which is a small, through-hole package that can be easily mounted onto a circuit board.

Operating Conditions:

The maximum operating temperature for the BC636 is 150°C.

The recommended operating conditions for the transistor are as follows:

Collector-Emitter Voltage (VCEO): 45V

Collector Current (IC): 1 A

Operating Temperature: -55°C to 150°C

Applications:

The low noise characteristics and high transition frequency of the BC636 make it suitable for use in low noise amplifier circuits.

The high current rating of the transistor also makes it suitable for use in switching applications.

Other applications for the BC636 include audio pre-amplifiers, audio amplifiers, and RF amplifiers.

About Swagatam

I am an electronics engineer and doing practical hands-on work from more than 15 years now. Building real circuits, testing them and also making PCB layouts by myself. I really love doing all these things like inventing something new, designing electronics and also helping other people like hobby guys who want to make their own cool circuits at home.

And that is the main reason why I started this website homemade-circuits.com, to share different types of circuit ideas..

If you are having any kind of doubt or question related to circuits then just write down your question in the comment box below, I am like always checking, so I guarantee I will reply you for sure!
