BC847SH6827XTSA1

Overview

The BC847SH6827XTSA1 is a dual NPN bipolar junction transistor manufactured by Infineon Technologies. It is housed in a SOT-363 (SC-70/SC88) surface-mount package containing two electrically isolated transistors within a single compact footprint. The device features a collector-emitter voltage rating of 45 V and a maximum continuous collector current of 100 mA per transistor. With a DC current gain ranging from 200 to 450, it supports efficient signal amplification. The component operates reliably across an extended temperature range from -65 °C to +150 °C and meets AEC-Q101 automotive qualification standards for robust performance in demanding environments.

Feature Summary

• Dual configuration with galvanic isolation between internal transistors
• High DC current gain suitable for sensitive signal processing
• Compact SOT-363 surface-mount packaging for space-constrained designs
• Automotive-grade reliability compliant with AEC-Q101 standards

Applications

• Audio input stages requiring low noise and high fidelity
• Driver applications for small-signal control circuits
• General-purpose switching and amplification in consumer electronics

Procurement Notes

Verify the specific suffix XTSA1 against official Infineon documentation to confirm tape-and-reel packaging specifications. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity. Cross-reference the full part number with the latest datasheet revision to confirm compliance with RoHS directives and material declarations before finalizing orders.

Selection Notes

Select this component when a design requires two matched or independent NPN transistors in a minimal board area. The high current gain makes it appropriate for pre-amplification tasks where signal integrity is critical. Consider the thermal resistance characteristics if multiple units are placed in close proximity on the PCB layout.

Part Context

This part belongs to the BC847 series of dual NPN transistors designed for audio frequency and general-purpose applications. It shares the same pinout and mechanical dimensions as other variants in the family but may differ in specific electrical parameters or packaging configurations. The series is widely used in portable devices due to its small form factor and reliable switching characteristics.

Replacement Considerations

Direct replacements include BC847S variants from other manufacturers that match the SOT-363 package and 45V rating. Verify pin compatibility and ensure the substitute meets the required hFE range and power dissipation limits for the specific application.
