BC547B NPN bipolar transistor

Model: BC547B
Marking on the package: BC547 / B 080
Type: NPN bipolar transistor
Current gain group: B
Package: TO-92
Mounting: through-hole THT
Number of leads: 3
Quantity: 10 pieces

BC547B reference parameters:

Maximum collector-emitter voltage VCEO: 45 V
Maximum collector-base voltage VCBO: 50 V
Maximum emitter-base voltage VEBO: 6 V
Maximum continuous collector current IC: 100 mA
Power dissipation: up to 625 mW at an ambient temperature of 25°C, under catalogue conditions
Current gain hFE for group B: 200–450 at VCE = 5 V and IC = 2 mA
Collector-emitter saturation voltage VCE(sat): max. 0.25 V at IC = 10 mA and IB = 0.5 mA
Collector-emitter saturation voltage VCE(sat): max. 0.6 V at IC = 100 mA and IB = 5 mA
Junction and storage temperature: −55°C to +150°C
Detailed parameters may vary between different BC547B versions. Permissible power dissipation depends on temperature and heat dissipation conditions.

Pinout:

⚠ WARNING
The specified voltages, current and power are limit values or depend on defined catalogue conditions. They do not imply simultaneous operation at all maximum ratings.

Safe use

✓ Install and remove only with the power disconnected.
✓ Do not exceed the permissible voltages, collector current or power dissipation.
✓ Take ambient temperature and heat dissipation conditions into account.
✓ Confirm the pinout of the specific component before soldering.
✓ Use standard electrostatic-discharge precautions when handling the component.

Possible replacements

Before using a transistor with similar parameters, compare its type, permissible voltages and currents, power dissipation, gain, package, pinout and operating conditions. The list of possible replacements does not imply automatic 1:1 compatibility.

Soldering and storage

Avoid excessive or prolonged heating during soldering. Store in a dry, clean place and protect against moisture, mechanical damage and electrostatic discharge.
