BC847BW

Overview

The BC847BW is an NPN small-signal bipolar junction transistor manufactured by Shenzhen Slkormicro Semicon Co., Ltd. It is housed in a compact SOT-23 surface-mount package, designed for efficient automatic insertion and space-constrained circuit layouts. The device operates with a collector-emitter voltage of 45V and a continuous collector current of 100mA. It features a DC current gain (hFE) range of 200 to 450, ensuring reliable amplification performance. The component supports a wide operating temperature range from -55°C to +150°C and dissipates up to 325mW of power, making it suitable for general-purpose switching and linear amplifier applications.

Feature Summary

Procurement Notes

Verify the manufacturer designation on the component marking against official Shenzhen Slkormicro Semicon documentation. Confirm the specific hFE binning code corresponds to the required gain range for your design. Ensure the package type matches the PCB footprint specifications. Request RoHS compliance certificates if environmental regulations apply to your production line.

Selection Notes

Select this component when a low-cost, high-gain NPN transistor is required for small-signal tasks. The SOT-23 package is ideal for dense PCB layouts where space is limited. Consider the 45V voltage rating and 100mA current limit to ensure operation within safe boundaries. Verify that the thermal dissipation requirements are met by the board layout.

Part Context

This part belongs to the BC847 series of NPN transistors, which are widely used in consumer electronics and industrial control systems. The 'W' suffix typically denotes the specific tape-and-reel packaging format for automated manufacturing. Shenzhen Slkormicro Semicon produces this device as part of its discrete semiconductor portfolio, focusing on cost-effective solutions for mass-market electronic applications.

Replacement Considerations

Compatible substitutes include the BC847B from other manufacturers such as onsemi or ROHM, provided the pinout and electrical characteristics match. Verify that alternative sources offer the same SOT-23 package and hFE gain range to ensure functional equivalence without redesigning the circuit.
