- RF signal processing modules
Procurement Notes
Verify the manufacturer designation as Fairchild Semiconductor during acquisition. Confirm compliance with RoHS standards and lead-free status. Ensure the TO-92 package type matches the design requirements. Validate the specific ordering suffix against official documentation to confirm pinout and electrical characteristics.
Selection Notes
Select this component when a small-signal NPN transistor with low collector current capability is required. The 20 V breakdown voltage limits suitability for high-voltage applications. Verify that the very high frequency band rating aligns with the target circuit's operational speed requirements.
Part Context
This part belongs to the discrete semiconductor transistor category, specifically within the NPN bipolar junction transistor segment. It is classified under the Very High Frequency Band JEDEC standard. The component utilizes silicon epitaxial planar technology for performance optimization.
Replacement Considerations
Consult official Fairchild Semiconductor cross-reference documents for verified substitutes. Generic equivalents must match the NPN polarity, TO-92 package, and 20 V / 0.02 A ratings. Do not assume compatibility based on similar part numbers without datasheet verification.
