BC856S,115

Overview

The BC856S,115 is a PNP/PNP general-purpose transistor pair manufactured by Nexperia USA Inc. It is housed in a TSSOP6 (SOT363-3) surface-mount package with six leads. Key electrical parameters include a collector-emitter voltage of -65 V and a maximum collector current of -100 mA per transistor. The device features closely matched current gain with a minimum hFE of 110 at VCE = -5 V and IC = -2 mA. Total power dissipation reaches 300 mW per device at Tamb ≤ 25 °C on a standard footprint. The transition frequency is specified at 100 MHz.

Feature Summary

• Low collector capacitance for high-frequency performance
• Low collector-emitter saturation voltage
• Closely matched current gain between transistors
• No mutual interference between the internal transistors

Applications

• General-purpose switching
• Amplification circuits

Procurement Notes

Verify the specific ordering suffix to confirm the packaging format, as the base part number BC856S corresponds to the component while the suffix indicates reel or cut tape variations. Confirm RoHS compliance status and ensure the supplier provides the original manufacturer datasheet for accurate pinout and thermal data verification before finalizing procurement orders.

Selection Notes

Select this component when a dual PNP configuration is required in a compact SOT363-3 footprint. Ensure the application operates within the -65 V collector-emitter voltage limit and does not exceed the 100 mA collector current rating per transistor. Verify that the total power dissipation requirements align with the available thermal resistance values for the intended PCB mounting conditions.

Part Context

This component belongs to the BC856 series of general-purpose PNP transistors produced by Nexperia. It serves as a dual-transistor solution designed to reduce component count and board space compared to using discrete single transistors. The SOT363-3 package allows for efficient surface-mount assembly in space-constrained electronic designs.

Replacement Considerations

BC856BSH is a documented replacement option offering matched double transistor characteristics.
