BC846UE6727HTSA1

Overview

The BC846UE6727HTSA1 is a dual NPN silicon bipolar junction transistor (BJT) array manufactured by Infineon Technologies. It is housed in a surface-mount SC-74-6 package, also known as SOT-363. The device features two internally isolated transistors within a single compact footprint. Key electrical ratings include a maximum collector-emitter voltage of 65 V and a collector-base voltage of 80 V. The continuous DC collector current is rated at 100 mA, with a peak collector current capability of 200 mA for pulses up to 10 ms. Total power dissipation is limited to 250 mW. The component operates within a temperature range of -65°C to +150°C.

Feature Summary

• Dual NPN configuration with galvanic isolation between internal transistors
• High DC current gain suitable for amplification applications
• Low collector-emitter saturation voltage for efficient switching
• Automotive qualification compliant with AEC-Q101 standards

Applications

• Audio frequency input stages
• General-purpose driver circuits
• Switching applications requiring high gain
• Signal processing in automotive electronics

Procurement Notes

Verify the specific ordering suffix HTSA1 against official Infineon documentation to confirm tape-and-reel packaging quantities and marking codes. Confirm RoHS compliance status through the manufacturer's latest product data sheet. Ensure the SC-74 package dimensions match the target PCB layout requirements before finalizing procurement decisions.

Selection Notes

Select this component when a dual NPN configuration with galvanic isolation is required in a minimal surface-mount footprint. The BC846U series offers higher breakdown voltages compared to lower-voltage variants. Consider the thermal resistance characteristics and power dissipation limits relative to the expected operating current and ambient temperature conditions during circuit design.

Part Context

This part belongs to the BC846/BC847 family of small-signal NPN transistors. The 'U' designation typically indicates the SC-74 (SOT-363) package variant. These devices are commonly used in portable electronics and automotive systems due to their low profile and high reliability. The HTSA1 suffix denotes specific manufacturing and packaging details defined by Infineon.

Replacement Considerations

Direct replacements include other BC846U variants from Infineon or equivalent dual NPN arrays from other manufacturers such as ON Semiconductor or Diodes Inc., provided pinouts and electrical parameters match. Verify that substitute components meet the same AEC-Q101 automotive qualification if required for the application.
