MPSA27RLRA

Single Bipolar Transistors Overview

The MPSA27RLRA is an NPN Darlington transistor manufactured by onsemi, housed in a SOT-54 (TO-92) plastic package. It features a maximum collector current of 500 mA and a maximum collector-emitter voltage of 60 V. The device provides high DC current gain with a minimum specification of 10,000. These electrical characteristics support its use in applications requiring high gain amplification within low-voltage circuit designs.

Single Bipolar Transistors Feature Summary

• High DC current gain capability for signal amplification
• NPN Darlington configuration for enhanced sensitivity
• Low voltage operation suitable for general-purpose switching

Single Bipolar Transistors Applications

• High gain amplification circuits
• General-purpose switching applications
• Low-voltage control interfaces

Single Bipolar Transistors Procurement Notes

Verify the specific suffix RLRA against official datasheets to confirm tape-and-reel packaging and quantity specifications. Ensure the component matches the SOT-54 package outline and electrical ratings defined by onsemi. Cross-reference manufacturer part numbers to avoid confusion with equivalent devices from other vendors.

Single Bipolar Transistors Selection Notes

Select this component when high current gain is required in a compact TO-92 form factor. The 60 V rating limits suitability for high-voltage power stages. Consider thermal dissipation requirements for continuous 500 mA operation. Verify compatibility with existing PCB footprints designed for the SOT-54 package style.

Single Bipolar Transistors Part Context

This part belongs to the MPSA27 family of NPN Darlington transistors. It shares core electrical specifications with variants such as the standard MPSA27 but differs in packaging or reel configuration. The RLRA suffix typically indicates a specific bulk or reel packing option provided by the manufacturer for automated assembly processes.

Single Bipolar Transistors Replacement Considerations

Equivalent parts include PMBTA13 and BCV29. Verify pinout compatibility and exact gain ranges before substitution. Check if alternative packages meet spatial constraints.
