2PC4081S/ZLX

Single Bipolar Transistors Overview

The 2PC4081S/ZLX is an NPN general-purpose bipolar junction transistor (BJT) manufactured by Nexperia, a brand under the NXP portfolio. It is housed in a SOT-323 (SC-70) plastic surface-mount package. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 50 V, a maximum DC collector current of 150 mA, and a power dissipation of 200 mW. The device features a gain-bandwidth product (fT) of 100 MHz and operates within a temperature range of -65°C to +150°C.

Single Bipolar Transistors Feature Summary

• NPN polarity configuration for switching and amplification
• Low voltage operation capability up to 50 V
• Compact SOT-323 surface-mount packaging

Single Bipolar Transistors Applications

• General-purpose switching circuits
• Small signal amplification

Single Bipolar Transistors Procurement Notes

Verify that the suffix /ZLX corresponds to the specific tape-and-reel packaging variant intended for automated assembly. Confirm RoHS compliance status through official datasheets or manufacturer declarations prior to integration into regulated products. Ensure the component source is authorized to avoid counterfeit risks.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring low-current NPN switching in space-constrained applications. The SOT-323 package suits high-density PCB layouts. Verify that the 150 mA current rating and 50 V voltage limits align with the circuit's operational requirements and thermal management capabilities.

Single Bipolar Transistors Part Context

This part belongs to the Nexperia BJT family, specifically designed as a complement to PNP devices like the 2PA1576. It is widely used in consumer electronics and industrial control systems where small form factor and reliable switching performance are required. The SOT-323 package is standard for low-power discrete transistors.

Single Bipolar Transistors Replacement Considerations

The 2PA1576 is the documented PNP complement. For direct NPN replacements, verify pinout compatibility with other SOT-323 NPN transistors offering similar VCEO and IC ratings from manufacturers such as Diodes Inc. or ON Semiconductor.
