PN918 APM PBFREE

Overview

The PN918 APM PBFREE is an NPN general-purpose switching bipolar junction transistor manufactured by Central Semiconductor. It utilizes silicon technology and is housed in a TO-92-3 through-hole package. Key electrical specifications include a maximum DC collector current of 50 mA, a collector-emitter voltage (VCEO) of 15 V, and a collector-base voltage (VCBO) of 30 V. The device features a minimum DC current gain (hFE) of 20, a transition frequency (fT) of 600 MHz, and a power dissipation rating of 625 mW. It operates within a temperature range of -65°C to +150°C.

Feature Summary

• Designed for general-purpose switching applications with high-speed performance capabilities.
• Constructed using silicon planar epitaxial technology for reliable operation.
• Configured as a single NPN transistor suitable for low-power circuit integration.

Applications

• General-purpose signal switching circuits
• Low-power amplifier stages
• Digital logic interface buffers

Procurement Notes

Verify the specific suffix 'APM' against the manufacturer's official datasheet to confirm packaging details, as standard listings may indicate bulk packaging. Ensure RoHS compliance documentation matches the PBFREE designation. Cross-reference the part number with authorized distributors to confirm current availability and manufacturing status before finalizing procurement plans.

Selection Notes

Select this component for designs requiring moderate switching speeds indicated by the 600 MHz transition frequency. The 50 mA collector current limit defines its suitability for low-power applications rather than high-current driving tasks. Verify that the 15 V collector-emitter voltage rating aligns with the circuit's supply requirements and transient conditions.

Part Context

This component belongs to the PN918 series of NPN transistors produced by Central Semiconductor. It serves as a silicon-based discrete semiconductor device intended for use in various electronic assemblies where general-purpose switching and amplification are required. The product line focuses on standard through-hole configurations for prototyping and production.

Replacement Considerations

Consult official substitution guides for equivalent NPN transistors with similar voltage and current ratings. Verify pinout compatibility and thermal characteristics when considering alternative manufacturers. No direct substitute part numbers are confirmed in the provided source material.
