BC846BSH-QF

Overview

The BC846BSH-QF is a dual NPN general-purpose transistor manufactured by Nexperia, housed in the SOT363-3 (SC-88) surface-mount package. It features a collector-emitter voltage (VCEO) of 65 V and a continuous collector current (IC) of 100 mA per element. The device exhibits a DC current gain (hFE) range of 200 to 450 at IC = 2 mA and VCE = 5 V, with a transition frequency (fT) of 100 MHz. Power dissipation is rated at 200 mW. Qualified under AEC-Q101, it supports operating junction temperatures up to 175 °C.

Feature Summary

• Dual NPN configuration with internal isolation between transistors
• AEC-Q101 qualified for automotive reliability standards
• High-temperature operation capability up to 175 °C
• Low collector capacitance and closely matched current gain

Applications

• General-purpose switching and amplification circuits
• Current mirror configurations requiring matched characteristics
• Differential amplifier stages
• Automotive electronic systems

Procurement Notes

Verify the specific suffix 'QF' against official Nexperia documentation to confirm tape-and-reel packaging specifications and quantity per reel. Ensure the component meets AEC-Q101 requirements if used in automotive designs. Cross-reference datasheets for thermal resistance values relevant to the specific PCB layout.

Selection Notes

Select this component when space-constrained dual NPN switching or amplification is required in automotive environments. The SOT363-3 package offers board space savings compared to discrete single transistors. Verify that the 100 mA current rating and 65 V voltage limits align with the circuit design parameters.

Part Context

This part belongs to the BC846SH series of dual NPN transistors designed for high-temperature applications. It serves as a compact alternative to using two separate single transistors, providing matched electrical characteristics essential for precision analog circuits like differential pairs.

Replacement Considerations

BC846BSH-Q is the non-qualified equivalent. BCM846BS is a standard commercial grade dual NPN transistor. BC846B is a single NPN transistor requiring two units for equivalent functionality.
