JAN2N4854U

Overview

The JAN2N4854U is a dual small-signal bipolar junction transistor (BJT) manufactured by Microchip Technology. It integrates NPN and PNP transistors in a single U-6 surface-mount package. The device supports a maximum DC collector current of 600 mA and operates with a collector-emitter voltage (VCEO) of 40 V. Key electrical parameters include a collector-base voltage (VCBO) of 60 V, an emitter-base voltage (VEBO) of 5 V, and a power dissipation rating of 600 mW. The component functions within a temperature range of -65°C to +200°C.

Feature Summary

• Dual configuration combining NPN and PNP structures for complementary circuit applications
• High thermal stability enabling operation up to +200°C junction temperature
• Surface-mount U-6 packaging designed for automated assembly processes

Applications

• Complementary switching circuits requiring matched NPN/PNP pairs
• Push-pull amplifier stages in signal processing systems
• Digital logic interface circuits utilizing dual transistor configurations

Procurement Notes

Verify the specific suffix 'U' against official Microchip documentation to confirm surface-mount compatibility and pinout definitions. Ensure procurement channels provide traceability data consistent with military-grade JAN specifications. Confirm RoHS status and material declarations align with project requirements before finalizing orders.

Selection Notes

Select this component when a compact dual BJT solution is required for space-constrained designs. Compare the 600 mW power dissipation limit against thermal management capabilities in the target application. Verify that the U-6 package dimensions fit the printed circuit board layout constraints and soldering profiles.

Part Context

This part belongs to the 2N4854 family of dual small-signal transistors. The JAN prefix indicates compliance with military quality standards, while the 'U' suffix typically denotes the specific surface-mount variant. It serves as a semiconductor alternative to through-hole TO-78 packages for modern SMT manufacturing lines.

Replacement Considerations

The 2N4854U is the direct through-hole equivalent in terms of electrical characteristics but differs in physical mounting. Verify pinout compatibility if substituting with other dual BJT packages such as SC-90 or SOT-363 variants.
