Overview
The BC846AS-7 is a dual NPN small-signal surface mount transistor manufactured by Diodes Incorporated. It operates within a collector-emitter voltage (VCEO) of 65 V and a collector-base voltage (VCBO) of 80 V, with an emitter-base voltage (VEBO) of 6 V. The maximum DC collector current is 100 mA, while peak currents reach 200 mA for both collector and base. Power dissipation is rated at 200 mW, supported by a thermal resistance of 625 °C/W. The device features a gain-bandwidth product (fT) of 100 MHz and operates across a temperature range from -65 °C to +150 °C.
Feature Summary
- Dual NPN configuration housed in an ultra-small SOT363 surface mount package designed for automated insertion.
- Qualified to AEC-Q101 standards for high reliability applications.
- Totally lead-free, fully RoHS compliant, and halogen and antimony free.
Applications
- Switching circuits
- Audio frequency (AF) amplifier applications
Procurement Notes
Verify the specific ordering suffix '-7' against official documentation to confirm reel size and tape width specifications. Ensure compliance requirements match project needs, as automotive-compliant variants may be available under separate datasheets. Confirm that the standard BC846AS meets all necessary environmental and safety certifications before finalizing procurement.
Selection Notes
Select this component when a compact dual NPN transistor is required for space-constrained designs. The SOT363 package offers a smaller footprint compared to single-transistor alternatives. Consider the 100 mA current rating and 65 V breakdown voltage to ensure suitability for the intended signal levels and switching loads.
Part Context
This part belongs to the BC846 series of small-signal transistors. It serves as the dual NPN counterpart to single NPN versions and complements the PNP type BC856AS. The device is engineered for general-purpose low-power electronics requiring matched pairs in a minimal surface-mount form factor.
Replacement Considerations
Check for BC846ASQ if automotive qualification is strictly required. Verify pinout compatibility with other SOT363 dual NPN transistors before substitution.
FAQ
What is the ESD rating for the BC846AS?
The device has an ESD rating of 4,000 V according to the Human Body Model (HBM) JEDEC Class 3A, and 400 V according to the Machine Model (MM).
Is the BC846AS suitable for automotive applications?
The standard BC846AS is qualified to AEC-Q101 standards. However, a specific automotive-compliant part, BC846ASQ, is available under a separate datasheet.
What is the typical DC current gain (hFE) range?
The DC current gain (hFE) ranges from a minimum of 110 to a maximum of 220, measured at VCE = 5V and IC = 2mA.
