MPSA29-D26Z

Single Bipolar Transistors Overview

The MPSA29-D26Z is a small signal NPN silicon Darlington transistor manufactured by onsemi. It features a TO-92 through-hole package with three terminals. The device supports a continuous collector current of 0.5 A and withstands a collector-emitter voltage of 80 V. Key electrical characteristics include a minimum DC current gain (hFE) of 10,000 and a maximum operating junction temperature of 150 °C. The component is designed for general-purpose amplification and switching applications in electronic circuits.

Single Bipolar Transistors Feature Summary

• High current gain capability suitable for sensitive signal amplification
• Robust thermal performance allowing operation up to 150 °C
• Through-hole construction for reliable mechanical mounting

Single Bipolar Transistors Applications

• General-purpose amplifier circuits
• Switching applications in low-power electronics
• Driver stages for relays or LEDs

Single Bipolar Transistors Procurement Notes

Verify the manufacturer marking and date code against official onsemi documentation to ensure authenticity. Confirm that the specific suffix matches the required pinout and electrical specifications for your design. Request the latest datasheet from authorized distributors to validate compliance with RoHS directives and other regulatory standards applicable to your region.

Single Bipolar Transistors Selection Notes

Select this component when high current gain is required for driving loads with minimal base current. The TO-92 package is appropriate for prototyping and low-volume production where through-hole assembly is preferred. Ensure the circuit design accounts for the Darlington configuration's higher saturation voltage compared to single-transistor alternatives.

Single Bipolar Transistors Part Context

This part belongs to the MPSA29 series of NPN Darlington transistors. It is functionally similar to the MPSA13 but offers higher current handling capabilities. The D26Z suffix typically denotes specific packaging or tape-and-reel variations depending on the manufacturer's coding system, though the core electrical characteristics remain consistent with the standard MPSA29 specification.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include the MPSA13 and MPSA28 (PNP complement). Verify pin compatibility and thermal dissipation requirements before substitution. Alternative manufacturers such as Fairchild or Texas Instruments produce equivalent parts under different part numbers.
