Overview
The BC859AMTF is a PNP silicon small signal transistor manufactured by Fairchild Semiconductor. It operates with a maximum collector current of 100 mA and a collector-emitter voltage rating of 45 V. The device is housed in a SOT-23 surface-mount package, designated as R-PDSO-G3, featuring three leads. It exhibits a minimum DC current gain (hFE) of 110 and supports a maximum operating junction temperature of 150 °C. The component is lead-free and RoHS compliant.
Feature Summary
- PNP epitaxial silicon construction for reliable small-signal amplification
- SOT-23 surface-mount packaging for compact circuit integration
- Lead-free and RoHS compliant manufacturing process
Applications
- General-purpose switching applications
- Small-signal amplifier circuits
- Complementary pairing with NPN transistors
Procurement Notes
Verify the manufacturer marking matches Fairchild Semiconductor specifications. Confirm the SOT-23 package code and pinout configuration align with design requirements. Ensure compliance with lead-free and RoHS standards if required by project regulations. Cross-reference datasheet electrical characteristics against system constraints before procurement.
Selection Notes
Select this component for low-power PNP switching or amplification tasks requiring a compact SOT-23 footprint. Consider the 45 V breakdown voltage and 100 mA current limits when designing bias networks. Verify thermal management capabilities within the 150 °C junction temperature limit. Compare hFE ranges against specific gain requirements for the intended application circuit.
Part Context
This part belongs to the BC859 series of PNP small signal transistors. It serves as a complementary device to NPN counterparts like the BC847 series. The AMTF suffix typically indicates specific binning or tape-and-reel packaging variations within the standard BC859 product line.
Replacement Considerations
Direct substitutes include other PNP transistors with identical SOT-23 packaging and matching electrical ratings. Verify pinout compatibility and thermal characteristics before substitution.
