Overview
The BC846S-AQ is a dual NPN bipolar junction transistor (BJT) array manufactured by Diotec Semiconductor. It is housed in an SOT-363 surface-mount package and designed for general-purpose switching and amplification applications. The device features a maximum collector-emitter voltage of 45V, a continuous collector current of 100mA, and a power dissipation rating of 250mW. It operates within a temperature range of -55°C to +150°C and meets AEC-Q101 automotive qualification standards.
Feature Summary
- Automotive-grade reliability certified under the AEC-Q101 standard
- Dual NPN configuration with galvanic isolation between transistors
- Compact SOT-363 surface-mount packaging for space-constrained designs
Applications
- Automotive input stages and driver circuits
- General-purpose signal switching
- Low-voltage amplification tasks
Procurement Notes
Verify that the specific suffix 'AQ' denotes AEC-Q101 automotive qualification, as this distinguishes it from standard commercial variants like the BC846S. Confirm RoHS compliance status and check for any recent PCN updates regarding material changes or manufacturing site transfers before finalizing procurement orders.
Selection Notes
Select the BC846S-AQ when automotive reliability is required for dual NPN applications. Ensure the design voltage does not exceed 45V. Compare against the BC847S-AQ if a lower 45V rating is acceptable but different gain characteristics are needed. Verify pinout compatibility with existing SOT-363 footprints.
Part Context
This component belongs to the BC846 series of small-signal NPN transistors. It shares the same physical footprint and electrical limits as the BC846S but includes additional automotive qualification testing. It serves as a dual-transistor alternative to single packages like the BC846B, offering matched characteristics in a compact form factor.
Replacement Considerations
The BC847S-AQ is listed as a parameter-equivalent substitute. Standard commercial versions such as the BC846S may be used if automotive certification is not strictly required.
