Overview
The BC858AMTF is a PNP epitaxial silicon small-signal transistor manufactured by Fairchild Semiconductor. It is housed in a SOT-23 surface-mount package with three leads. The device supports a maximum collector current of 100 mA and a collector-emitter voltage rating of -30 V. It features a minimum DC current gain (hFE) of 200, ensuring high amplification capability for low-power applications. The component operates within a junction temperature range up to 150 °C and complies with lead-free and RoHS standards.
Feature Summary
- PNP epitaxial silicon construction for reliable small-signal performance
- High DC current gain suitable for amplification tasks
- Surface-mount SOT-23 packaging for compact circuit integration
Applications
- General-purpose signal amplification
- Switching circuits in low-power electronics
- Audio pre-amplifier stages
Procurement Notes
Verify the manufacturer marking and date code on the component body to confirm authenticity. Ensure the ordering suffix matches the required tape-and-reel or cut-tape format specified in the purchase order. Confirm that the batch meets the requested environmental compliance standards prior to final acceptance.
Selection Notes
Select this component when a PNP transistor with a -30 V collector-emitter voltage rating and a minimum hFE of 200 is required. The SOT-23 package is appropriate for space-constrained designs. Consider the BC857 series if a higher voltage rating of -45 V is needed instead.
Part Context
This part belongs to the BC858 family of PNP transistors from Fairchild Semiconductor. It serves as a complement to NPN devices like the BC848. The 'A' suffix typically denotes a specific binning of current gain characteristics, while 'MTF' indicates the SOT-23 package and manufacturing traceability.
