Overview
The BC847BW,135 is an NPN general-purpose transistor from the Nexperia BC847xW series, housed in a SOT323 (SC-70) surface-mount package. It features a collector-emitter voltage of 45 V and a continuous collector current of 100 mA. The device offers a DC current gain (hFE) range of 200 to 450 at VCE = 5 V and IC = 2 mA. Total power dissipation is rated at 200 mW with a maximum junction temperature of 150 °C. Transition frequency is specified at 100 MHz.
Feature Summary
- General-purpose NPN switching and amplification capabilities
- Three distinct DC current gain selection groups for design flexibility
- Compact SOT323 plastic surface-mounted package
Applications
- General-purpose switching circuits
- Amplifier stages
Procurement Notes
Verify the specific ordering suffix matches the required packaging format before purchase. Confirm that the component is not automotive qualified unless explicitly designated with a -Q suffix. Ensure the selected gain bin aligns with circuit requirements. Check the latest datasheet revision for any updates to electrical characteristics or marking codes prior to finalizing procurement orders.
Selection Notes
Select this component when a compact NPN transistor with moderate gain is required. The BC847BW variant provides a guaranteed minimum hFE of 200, suitable for applications needing consistent amplification. Consider thermal resistance limits if operating near maximum power dissipation. Verify pinout compatibility with existing PCB footprints designed for the SC-70 package.
Part Context
This part belongs to the BC847xW series, which includes variants with different gain ranges: BC847AW, BC847BW, and BC847CW. All share the same physical package and basic electrical ratings but differ in their DC current gain specifications. The PNP complement for this series is the BC857W family.
Replacement Considerations
Direct substitutes within the same series include BC847AW,135 and BC847CW,135, provided the gain requirements are met. Cross-series replacements require verification of pinout, voltage ratings, and package dimensions.
