BCX6816H6327XTSA1

Overview

The BCX6816H6327XTSA1 is an NPN silicon audio frequency transistor from the BCX68 series, manufactured by Infineon Technologies. It features a collector-emitter voltage (VCEO) of 20 V and a continuous collector current (IC) of 1 A. The device provides a DC current gain (hFE) range of 100 to 250 at IC = 500 mA and VCE = 1 V. It operates with a maximum power dissipation of 3 W and a junction temperature up to 150 °C. The component utilizes a SOT-89 surface-mount package.

Feature Summary

• High current gain suitable for general audio frequency applications
• Low collector-emitter saturation voltage for efficient switching
• Automotive qualified according to AEC-Q101 standards

Applications

• General audio frequency amplification circuits
• Low-voltage switching applications
• Automotive electronic systems

Procurement Notes

Verify the specific suffix H6327XTSA1 against official Infineon documentation to confirm tape-and-reel packaging specifications. Ensure the selected variant matches the required hFE binning (100-250). Confirm RoHS compliance status directly with the manufacturer or authorized distributors before procurement.

Selection Notes

Select this component when a low-voltage NPN transistor with moderate current handling is required. The BCX6816 offers a balanced current gain profile compared to the BCX68-10 and BCX68-25 variants. Consider the complementary BCX69 PNP type if push-pull configurations are needed in the design.

Part Context

This part belongs to the BCX68 family of NPN silicon AF transistors designed for robust performance in consumer and automotive electronics. The series emphasizes high current capability and low saturation voltage within a compact SOT-89 footprint, facilitating space-constrained PCB layouts.
