Product Overview

The BC856B, developed by Guangdong Hottech Industrial Co., Ltd., is a high-performance PNP bipolar transistor in a SOT-23 surface-mount package. Designed for switching circuits, audio amplification, and automated manufacturing, its high current gain, low saturation voltage, and compact size make it ideal for consumer electronics, communication systems, and industrial control applications.

Key Features

High Current Gain

• DC current gain (hFE) range: 220-475 (Grade B), suitable for signal amplification and precision control.

Low Power Consumption

• Collector-emitter saturation voltage (VCE(sat)) as low as -0.5V (@ IC=-100mA), minimizing conduction losses.
• Maximum collector power dissipation (Pc): 200mW, enabling efficient energy management.

Surface-Mount Compatibility

• SOT-23 package with compact dimensions (2.8mm × 1.4mm), compatible with automated pick-and-place equipment.
• UL 94V-0 flammability certification ensures industrial-grade reliability.

Wide Voltage & Temperature Range

• Collector-base voltage (VCBO): -80V; collector-emitter voltage (VCEO): -65V.
• Operating temperature range: -55°C to +150°C, suitable for harsh environments.

Typical Applications

• Audio Amplification: Portable audio systems, headphone amplifier stages.
• Switching Circuits: Relay drivers, power management switches.
• Automation Systems: Sensor signal conditioning, industrial control modules.
• Consumer Electronics: Smart home controllers, low-power IoT devices.
