PEMX1,315

Overview

The PEMX1,315 is a dual NPN pre-biased transistor manufactured by Nexperia. It integrates two NPN bipolar junction transistors within a single SOT-883B (DFN1006-3) surface-mount package. The device features a collector-emitter voltage of 50 V and a continuous collector current of 100 mA. Typical internal base resistors are configured at 4.7 kΩ with a resistance ratio of 0.1. It operates reliably across an extended temperature range from -65°C to +150°C, ensuring stability in demanding electronic environments.

Feature Summary

• Dual NPN configuration integrated into a compact footprint
• Pre-biased design with typical 4.7 kΩ base resistors
• High thermal stability for operation up to 150°C

Applications

• Switching applications in automotive electronics
• Driver circuits for low-power loads
• Logic level translation interfaces

Procurement Notes

Verify the specific ordering code suffix against official Nexperia documentation to confirm package orientation and tape-and-reel specifications. Confirm RoHS compliance status through the manufacturer's latest declaration. Ensure the component meets AEC-Q101 qualification requirements if intended for automotive-grade assemblies.

Selection Notes

Select this component when space constraints require dual switching functions in a minimal outline. The integrated biasing simplifies circuit design by reducing external resistor count. Verify that the 100 mA current rating aligns with load requirements and that the 50 V breakdown voltage exceeds peak operating voltages.

Part Context

This part belongs to Nexperia's portfolio of pre-biased resistors (PBR) designed to simplify digital switching circuits. The SOT-883B package provides a small form factor suitable for high-density PCB layouts. It serves as a direct replacement for discrete NPN transistor pairs requiring identical biasing characteristics.

Replacement Considerations

Check pinout compatibility with existing footprints. Verify that substitute components match the 50 V Vceo and 100 mA Ic ratings. Ensure the replacement offers equivalent hFE characteristics and thermal performance.
