C3953 transistor


This is 120V, 0.2A, NPN Epitaxial Planar Silicon Transistor.

The C3953 NPN transistor is a type of bipolar junction transistor (BJT) that consists of two n-type semiconductor materials separated by a single p-type material.

The NPN transistor is used to amplify or switch electronic signals and is widely used in many electronic circuits. It works by controlling the current flow between the collector and emitter terminals through the base terminal.



1. High fT: fT=400MHz.

2. High breakdown voltage : VCEO=120Vmin.

3. Small reverse transfer capacitance and excellent HF response : Cre=1.7pF/NPN, 2.2pF/PNP.

4. Complementary PNP and NPN types.

5. Adoption of FBET process.
