Overview
The Fairchild Semiconductor 2N5210TF is an NPN silicon general-purpose amplifier transistor. It is housed in a TO-92 surface-mount package, specifically the SOT-23 form factor variant designated by the 'TF' suffix. The device is designed for low-noise audio frequency applications and general switching tasks. Key electrical characteristics include a collector-emitter breakdown voltage of 50 V and a continuous collector current rating of 100 mA. The component operates within a junction temperature range of -55 °C to +150 °C and features a maximum power dissipation of 350 mW.
Feature Summary
- Low noise performance suitable for audio pre-amplification stages
- Surface-mount compatible TO-92 (SOT-23) packaging for automated assembly
- High DC current gain optimized for linear amplification applications
Applications
- Audio pre-amplifier circuits
- General purpose signal amplification
- Switching applications in consumer electronics
Procurement Notes
Verify the specific manufacturer source, as the 2N5210 designation is shared across multiple vendors including ON Semiconductor and Central Semiconductor. Confirm that the 'TF' suffix corresponds to the correct surface-mount TO-92/SOT-23 package variant from Fairchild or its successor entities. Ensure RoHS compliance status matches the specific production lot requirements for the target application.
Selection Notes
Select this component when a small-form-factor NPN transistor with low noise characteristics is required for PCB space-constrained designs. Compare against standard through-hole TO-92 versions if surface-mount capability is not strictly necessary. Evaluate thermal management needs given the 350 mW power dissipation limit in the compact package.
Part Context
The 2N5210 is a legacy part number originally defined by JEDEC standards for NPN silicon transistors. Fairchild Semiconductor produced various package variants of this device. The 'TF' suffix typically denotes a specific tape-and-reel surface-mount version, distinct from the standard leaded TO-92 plastic package. This allows integration into modern SMT manufacturing lines while maintaining the established electrical profile of the 2N5210 family.
Replacement Considerations
Direct replacements may include the BC237 or MPS918 from ON Semiconductor, which share similar NPN amplifier characteristics. Verify pinout compatibility between the SOT-23/TO-92-SMD packages before substitution.
