Overview
The MPS5179RLRPG is an RF small signal bipolar transistor manufactured by onsemi. It is a silicon NPN device designed for very high frequency band applications. The component features a single-element configuration housed in a TO-92 cylindrical plastic/epoxy package with through-hole terminals. Key electrical specifications include a maximum collector current (IC) of 0.05 A, a maximum collector-emitter voltage (VCEO) of 12 V, and a minimum DC current gain (hFE) of 25. The device operates within a maximum power dissipation environment of 0.3 W and exhibits a maximum collector capacitance of 1 pF.
Feature Summary
- Designed for operation in the very high frequency band
- Integrates a single NPN silicon element for signal processing
- Provides input line reverse voltage protection capabilities
Applications
- RF small signal amplification circuits
- Very high frequency band signal processing
- General purpose switching applications requiring low current handling
Procurement Notes
Verify the manufacturer designation carefully, as the MPS5179 series is historically associated with Motorola and NXP. Confirm that the specific suffix RLRPG corresponds to the intended tape-and-reel packaging variant if automated assembly is required. Ensure the RoHS compliance status matches project requirements before finalizing procurement orders.
Selection Notes
Select this component when a low-power NPN transistor is needed for very high frequency applications. The 0.05 A collector current limit restricts usage to small signal environments. The TO-92 package suits through-hole prototyping or low-volume production where surface mount options are not mandatory. Verify the hFE minimum requirement aligns with circuit gain needs.
Part Context
This part belongs to the MPS5179 family of RF transistors. While originally developed by Motorola and later managed by NXP, the onsemi listing indicates current distribution or manufacturing rights. The RL suffix typically denotes reel packaging, distinguishing it from bulk TO-92 variants like the standard MPS5179.
Replacement Considerations
Direct substitutes may include other NPN RF transistors in TO-92 packages with similar VCEO and IC ratings. Check datasheets for comparable fT and capacitance values to ensure RF performance compatibility. Generic replacements must match the 0.3 W power dissipation limit.
