Overview
The BC856AMTF is a PNP silicon small signal transistor manufactured by Fairchild Semiconductor. It is housed in a SOT-23 (TO-236AB) plastic surface-mount package with three terminals. The device supports a maximum collector current of 100 mA and a collector-emitter voltage of 45 V. It features a minimum DC current gain (hFE) of 110. The component operates at junction temperatures up to 150 °C and complies with RoHS standards.
Feature Summary
- PNP configuration for general-purpose switching and amplification
- Low current handling capability suitable for small signal applications
- Surface-mount construction for automated insertion
Applications
- General purpose switching circuits
- Audio frequency amplifier stages
- Small signal processing applications
Procurement Notes
Verify the manufacturer origin, as the BC856A specification is widely standardized across multiple vendors including Nexperia and NXP. Confirm the specific hFE binning class matches the design requirements, as the 'A' suffix typically denotes a tighter gain range than standard variants. Ensure the SOT-23 footprint compatibility is validated against the target PCB layout before finalizing procurement.
Selection Notes
Select this component when a low-voltage PNP transistor is required for compact designs. The 45 V rating distinguishes it from higher voltage counterparts like the BC856 which offers 65 V. Consider the 100 mA current limit for load requirements. The SOT-23 package is ideal for space-constrained consumer electronics where leaded alternatives are unsuitable.
Part Context
This part belongs to the BC85x series of PNP general-purpose transistors. It serves as the PNP complement to the BC84x NPN series. The BC856 variant specifically provides a 45 V breakdown voltage, differentiating it from the BC857 (45 V but different gain bins) and BC858 (higher gain). It is designed for use in portable devices and battery-powered equipment.
Replacement Considerations
Direct pin-compatible substitutes include the BC856A from Nexperia or NXP. Verify that the replacement maintains the 45 V collector-emitter voltage rating and the 100 mA current limit. Check if the alternative manufacturer's hFE distribution aligns with the original Fairchild specifications.
