BC848A-AQ

Overview

The Diotec Semiconductor BC848A-AQ is an SMD general-purpose NPN transistor housed in a SOT-23 (TO-236) package. It features a collector-emitter voltage (VCEO) of 30 V, a collector-base voltage (VCBO) of 30 V, and a maximum DC collector current (IC) of 100 mA. The device supports a peak collector current (ICM) of 200 mA with a power dissipation (Ptot) of 300 mW for industrial and AEC-Q101 grades. It operates within a junction temperature range of -55°C to +150°C. The component utilizes gold bond wires and offers three current gain groups, with the 'A' group providing a minimum hFE of 180 at IC = 2 mA.

Feature Summary

• AEC-Q101 qualified automotive grade reliability
• Three distinct current gain groups available
• Gold wire bonding construction
• RoHS compliant without exemptions

Applications

• Signal processing circuits
• Electronic switching applications
• Amplification stages

Procurement Notes

Verify that the specific ordering suffix matches the required qualification level. Confirm the presence of the '-AQ' designation to ensure AEC-Q101 compliance. Check datasheet specifications for thermal resistance values based on the intended PCB pad layout. Ensure compatibility with RoHS and REACH regulations for the target market.

Selection Notes

Select this component when an NPN transistor with a 30 V collector-emitter rating is required. The BC848A variant provides higher current gain compared to lower letter designations. Consider the 300 mW power dissipation limit for industrial grades versus the 200 mW limit for commercial versions. Verify that the SOT-23 package dimensions fit the designated footprint.

Part Context

This part belongs to the BC846 through BC850 series of SMD universal NPN transistors manufactured by Diotec Semiconductor. The series covers various voltage ratings from 30 V to 65 V and includes complementary PNP counterparts. The BC848 specifically denotes the 30 V breakdown voltage category within this family.
