Overview
The BC848CW-7-F is an NPN small signal transistor manufactured by Diodes Incorporated in a SOT323 surface-mount package. It features a collector-emitter breakdown voltage of 30V and a continuous collector current rating of 100mA. The device belongs to the 'C' gain band, providing a minimum DC current gain (hFE) of 420 at 2mA. Electrical characteristics include a transition frequency of 100MHz and a maximum power dissipation of 200mW. Operating temperatures range from -65°C to +150°C.
Feature Summary
- Totally lead-free and fully RoHS compliant with halogen and antimony-free green packaging
- Ideally suited for automatic insertion into manufacturing equipment
- Complementary PNP types available within the BC856W–BC858W series
Applications
- Switching applications
- Audio Frequency (AF) amplifier circuits
Procurement Notes
Verify the specific ordering suffix '-7-F' against official Diodes Incorporated documentation to confirm the 3,000-unit reel size and SOT323 package marking code K1M. Ensure compliance requirements match project specifications, as the datasheet notes separate procedures for automotive-grade parts requiring AEC-Q100 qualification and IATF 16949 manufacturing certification.
Selection Notes
Select this component when high DC current gain is required for low-current amplification tasks. The 'C' band designation indicates a minimum hFE of 420, distinguishing it from lower gain variants. Verify that the 30V collector-emitter voltage rating aligns with circuit supply limits and that the SOT323 footprint matches the PCB layout constraints.
Part Context
This part belongs to the BC846AW–BC848CW family of NPN small signal transistors. The series utilizes an epitaxial silicon planar design optimized for general-purpose switching and amplification. The 'CW' suffix specifically denotes the SOT323 package format combined with the highest current gain grouping within the product line.
Replacement Considerations
Official complementary PNP counterparts are the BC856W, BC857W, and BC858W series. Cross-manufacturer equivalents may exist but require verification of pinout orientation and electrical parameter tolerances against the original datasheet specifications.
FAQ
What is the minimum DC current gain for the BC848CW?
The BC848CW belongs to the 'C' gain band, which specifies a minimum DC current gain (hFE) of 420 when tested at VCE = 5.0V and IC = 2.0mA.
Is the BC848CW-7-F suitable for automotive applications?
Standard production does not automatically qualify for automotive use. For applications requiring AEC-Q100/101/104/200 qualification and PPAP capability, customers must contact Diodes Incorporated directly or their local representative.
What is the ESD protection rating for this device?
The device meets JEDEC Class 3A for Human Body Model (HBM) testing at 4,000V, Class C3 for Charged Device Model (CDM) testing at 1,000V, and Class C for Machine Model (MM) testing at 400V.
