BC856A-HF

Overview

The BC856A-HF is a PNP silicon epitaxial planar general-purpose transistor manufactured by Comchip Technology. It features a collector-base voltage (VCBO) of -80V and a collector-emitter voltage (VCEO) of -65V, with an emitter-base voltage (VEBO) of -5V. The device supports a maximum continuous DC collector current of 100mA and a power dissipation of 250mW at 25°C ambient temperature. It utilizes the SOT-23 surface-mount package and operates within a junction temperature range of -65°C to +150°C. The 'A' suffix indicates a specific DC current gain (hFE) binning category.

Feature Summary

Utilizes silicon epitaxial planar technology for reliable switching and amplification
Designed for automatic insertion and high-volume surface mount assembly
Provides low current operation capabilities suitable for signal processing
Features wide operating and storage temperature ranges for industrial environments

Applications

General purpose switching circuits
Small signal amplification stages
Logic level translation interfaces
Driver circuits for low-power loads

Procurement Notes

Verify the specific hFE binning requirements against the manufacturer's datasheet, as the 'A' suffix denotes a defined gain range distinct from other variants. Confirm RoHS compliance status and halogen-free certification details directly from the official product documentation prior to finalizing procurement specifications.

Selection Notes

Select this component when a PNP transistor with -80V collector-base breakdown is required in a compact SOT-23 footprint. Ensure the application current remains below the 100mA limit and that thermal management accommodates the 250mW dissipation rating. Verify that the gain characteristics align with the circuit's biasing requirements.

Part Context

This part belongs to the BC85x series of general-purpose PNP transistors, which includes complementary NPN counterparts like the BC846 series. The series is widely used in consumer electronics and industrial control boards where small-signal handling and moderate voltage ratings are sufficient for standard logic and analog interface tasks.
