2N5401-AP

Overview

The 2N5401-AP is a PNP silicon amplifier transistor manufactured by Micro Commercial Components. It operates within an ambient temperature range of -55°C to +150°C and features a TO-92 through-hole package. Key electrical ratings include a collector-emitter voltage of -150 V, a collector-base voltage of -160 V, and a continuous collector current of -600 mA. The device dissipates up to 625 mW at 25°C with a thermal resistance of 200°C/W junction-to-ambient. Electrical characteristics specify a DC current gain (hFE) ranging from 40 to 200, a transition frequency of 100 MHz, and a noise figure of 8 dB.

Feature Summary

• Halogen-free construction available upon request via specific ordering suffixes
• Moisture sensitivity level 1 for standard handling requirements
• Epoxy material meets UL 94 V-0 flammability rating standards

Applications

• General-purpose small-signal amplification circuits
• Low-noise audio signal processing stages
• High-voltage switching applications requiring PNP polarity

Procurement Notes

Verify the exact part number against official distributor catalogs to confirm the presence of the AP suffix indicating ammo packing. Ensure compliance with RoHS directives if lead-free finish is required, as this may necessitate a different suffix. Confirm that the component is sourced from authorized distributors to avoid counterfeit parts and ensure full traceability according to manufacturer guidelines.

Selection Notes

Select this component when a PNP silicon transistor with high breakdown voltage and moderate current capability is needed. The TO-92 package suits low-power through-hole designs. Consider the specified hFE range and transition frequency for bandwidth requirements. Verify thermal derating curves for operation above 25°C to ensure power dissipation limits are not exceeded in the final assembly.

Part Context

This component belongs to the 2N5401 series of PNP bipolar junction transistors. It is designed for general-purpose amplification and switching tasks. The device utilizes silicon planar technology housed in a standard three-lead plastic encapsulated case. It serves as a fundamental discrete semiconductor element in electronic circuit design.

Replacement Considerations

Direct substitutes include other manufacturers' 2N5401 variants such as those produced by Central Semiconductor or Diotec Semiconductor. Verify pinout compatibility and electrical parameter overlap before substitution.
