BC856BS,135

Overview

The BC856BS is a PNP/PNP general-purpose transistor pair housed in a TSSOP6 (SOT363-3) surface-mounted plastic package. It features a collector-emitter voltage of -65 V and a continuous collector current of -100 mA per transistor, with peak ratings of -200 mA. The device offers closely matched current gain (hFE range 200–450 at VCE = -5 V, IC = -2 mA) and low collector capacitance (typical 2.3 pF). Total power dissipation reaches 300 mW for the dual device at 25 °C ambient temperature.

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 packaging format and reel specifications. Confirm that the SOT363-3 package variant matches the design footprint requirements. Ensure the manufacturing site code aligns with quality standards. Check for any recent revision updates in the product data sheet before finalizing procurement orders.

Selection Notes

Select this component when board space is limited due to its very small SOT363-3 package. Choose it for applications requiring matched current gain characteristics without external trimming. Consider the 300 mW total power dissipation limit when designing thermal management solutions for dense PCB layouts.

Part Context

This part belongs to Nexperia's general-purpose transistor portfolio. It serves as the PNP counterpart to the BC846BS NPN/NPN pair. The BC856BS provides a compact solution for differential pairs or current mirrors where space constraints preclude the use of larger leaded packages.

Replacement Considerations

BC846BS is the complementary NPN/NPN device within the same package family.
