BD14016STU

Overview

The onsemi BD14016STU is a PNP power transistor belonging to the BD140 series, designed for general-purpose amplification and switching applications. It features a collector-emitter voltage (VCEO) of 80 V and a continuous collector current (IC) of 1.5 A. The device utilizes a surface-mount SOT-323 package, providing a compact form factor suitable for space-constrained designs. Key electrical characteristics include a DC current gain (hFE) range typically specified between 40 and 250 at IC = 1.5 A, ensuring reliable performance in linear and saturated switching modes.

Feature Summary

• High current handling capability with a maximum collector current of 1.5 A
• Robust voltage rating supporting up to 80 V collector-emitter breakdown
• Compact SOT-323 surface-mount package for efficient PCB layout
• Suitable for general-purpose amplification and low-power switching tasks

Applications

• General-purpose amplifier circuits
• Low-power switching applications
• Driver stages for relays or LEDs
• Audio pre-amplification stages

Procurement Notes

Verify the exact ordering suffix 'STU' corresponds to the SOT-323 package and tape-and-reel quantity as defined in the official datasheet. Confirm RoHS compliance status and specific hFE binning requirements if precise gain matching is necessary for the application. Cross-reference the manufacturer's part number against distributor listings to ensure authenticity and correct revision level.

Selection Notes

Select this component when a PNP transistor with 80 V/1.5 A ratings is required in a small surface-mount footprint. Compare against alternative packages like SOT-89 or TO-92 if thermal dissipation needs differ. Ensure the application current remains within the 1.5 A limit and that the 80 V rating exceeds the maximum circuit voltage. Consider the thermal resistance of the SOT-323 package for heat management in dense layouts.

Part Context

This device is part of the BD140 family of PNP transistors from onsemi, which are widely used in consumer electronics and industrial control systems. The BD140 series offers a balance of voltage, current, and gain specifications suitable for versatile analog and digital switching roles. The BD14016 variant specifically denotes the 80 V/1.5 A specification within this lineup.

Replacement Considerations

Potential substitutes include other PNP transistors with similar 80 V/1.5 A ratings and SOT-323 packaging, such as the BC857 series (if current/voltage limits allow) or equivalent parts from manufacturers like STMicroelectronics or Diodes Inc. Verify pinout compatibility and thermal characteristics before substitution.
