Overview
The BCW61BMTF is a PNP silicon small signal transistor manufactured by Fairchild Semiconductor. It features a maximum collector current of 200 mA and a collector-emitter voltage rating of 32 V. The device is housed in a surface-mount SOT-23 package with three gull-wing terminals. Key switching parameters include a maximum turn-on time of 150 ns and a maximum turn-off time of 800 ns. The component is RoHS compliant, lead-free, and designed for general-purpose switching applications.
Feature Summary
- PNP silicon construction optimized for small-signal switching operations
- Integrated into a compact SOT-23 surface-mount package for automated assembly
- Capable of handling up to 200 mA collector current with fast switching dynamics
Applications
- General-purpose low-power switching circuits
- Signal processing stages requiring PNP transistor logic
- Embedded system interface drivers
Procurement Notes
Verify the specific suffix 'MTF' against official Fairchild documentation to confirm the exact tape-and-reel packaging configuration and terminal finish specifications. Ensure the procurement source provides valid RoHS compliance certificates matching the active status listed in public databases. Cross-reference the manufacturer part number with the distributor catalog to prevent substitution errors with similar BCW61 variants.
Selection Notes
Select this component when a PNP small-signal transistor with a 32 V breakdown voltage and 200 mA continuous current capacity is required. The SOT-23 form factor makes it suitable for space-constrained printed circuit board designs. Consider the 150 ns turn-on time for high-speed digital switching requirements where faster alternatives are not necessary.
Part Context
This device belongs to the BCW61 series of PNP transistors produced by Fairchild Semiconductor. The series is widely recognized for its reliability in consumer electronics and industrial control systems. The BCW61BMTF variant specifically denotes the surface-mount version, distinguishing it from through-hole equivalents while maintaining identical electrical characteristics within the family.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided reference data. Verify compatibility with equivalent PNP transistors such as the BCW61B or BCX54B only after consulting official cross-reference guides from Fairchild Semiconductor.
