BCM56DS-QX

Overview

The BCM56DS-QX is a dual NPN bipolar junction transistor manufactured by Nexperia. It utilizes silicon technology and is housed in a TSOP-6 (SOT457/SC-74) surface-mount package. The device supports a maximum DC collector current of 1 A and features a collector-emitter voltage (VCEO) of 80 V, with a collector-base voltage (VCBO) of 100 V and an emitter-base voltage (VEBO) of 5 V. Key electrical characteristics include a collector-emitter saturation voltage of 500 mV, power dissipation of 400 mW, and a gain-bandwidth product (fT) of 155 MHz. The component operates within a temperature range of -55 °C to +150 °C, with a DC current gain (hFE) ranging from a minimum of 63 to a maximum of 250.

Feature Summary

• Dual NPN configuration for compact circuit integration
• High thermal stability with a maximum operating temperature of +150 °C
• Robust voltage ratings suitable for general switching applications

Applications

• General-purpose switching circuits
• Low-power amplifier stages

Procurement Notes

Verify the specific suffix 'QX' against official Nexperia documentation to confirm automotive qualification status or specific tape-and-reel packaging requirements. Ensure the ordering part number matches the exact datasheet revision to avoid discrepancies in pinout or electrical tolerances during procurement.

Selection Notes

Select this component when a dual NPN topology is required in a small SC-74 footprint. Consider the 155 MHz transition frequency and 400 mW power dissipation limits for high-speed or thermally constrained designs. Verify that the 80 V collector-emitter rating aligns with the target circuit's supply voltage and transient conditions.

Part Context

This component belongs to Nexperia's portfolio of standard bipolar transistors designed for surface-mount assembly. The BC56 series typically offers a balance of current handling and voltage blocking capabilities. The 'Q' suffix often indicates compliance with automotive quality standards, while 'X' denotes reel packaging.
