NPN Silicon Epitaxial Planar Transistor for switching and AF amplifier application.

These transistors are subdivided into three groups A, B and C according to their current gain.

Functions :

1. Switching and Amplifie
2. Low current (max. 100 mA)
3. Low voltage (max. 65 V)
4. Low-Noise: BC549, BC550
5. Complement to BC556, BC557, BC558, BC559, and BC560

Absolute Maximum Ratings


Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits
are exceeded, device functional operation is not implied, damage may occur
and reliability may be affected.


· General purpose switching and amplification.
