BCM857BSHX

Overview

The BCM857BSH is a PNP/PNP matched double transistor manufactured by Nexperia USA Inc. It is housed in a SOT363 (SC-88) TSSOP6 surface-mount package with six leads and a 0.65 mm pitch. The device supports a collector-emitter voltage of -45 V and a continuous collector current of -100 mA per transistor. Key electrical parameters include a DC current gain (hFE) ranging from 200 to 450 at -2 mA, and a transition frequency of 100 MHz. The component is rated for operation up to a junction temperature of 175 °C and features low collector capacitance and tight base-emitter voltage matching.

Feature Summary

• Low collector capacitance and low collector-emitter saturation voltage
• Current gain and base-emitter voltage matching between transistors
• No mutual interference between the two transistors
• High-temperature applications up to 175 °C

Applications

• Current mirror
• Differential amplifier

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details and manufacturing site codes. Confirm that the product status aligns with current design requirements, as specifications may be subject to revision. Ensure compliance with RoHS directives and export control regulations applicable to the region of deployment.

Selection Notes

Select this component when a compact dual PNP configuration is required in a small SMD footprint. The tight matching characteristics make it suitable for precision analog circuits. Verify thermal management capabilities, as total power dissipation depends on PCB copper area and ambient temperature conditions.

Part Context

This part belongs to the BCM857 series of matched double transistors. The NPN/NPN complement is the BCM847BSH. It serves as a drop-in replacement for standard double transistors while reducing board space and pick-and-place costs due to its ultra-small plastic package dimensions.

Replacement Considerations

The BCM847BSH is the documented NPN/NPN complement. Standard double transistors in larger packages can be replaced by this unit to save board space.
