PEMH18,115

Overview

The PEMH18,115 is a dual NPN resistor-equipped transistor (RET) manufactured by Nexperia USA Inc. It integrates two NPN transistors with built-in bias resistors in an ultra-small SOT-666 surface-mounted package. The device supports a collector-emitter voltage of 50 V and a continuous output current of 100 mA per transistor. Key electrical parameters include a typical input resistance (R1) of 4.7 kΩ and a bias resistor ratio (R2/R1) of 2.1 at 25 °C. The total power dissipation is rated at 300 mW for the device and 200 mW per transistor at ambient temperatures up to 25 °C.

Feature Summary

• Integrates dual NPN transistors with built-in bias resistors to simplify circuit design
• Reduces component count and pick-and-place costs in digital applications
• Provides high DC current gain and low saturation voltage for efficient switching

Applications

• Low current peripheral driver circuits
• Control of IC inputs
• Replacement for general-purpose transistors in digital logic applications

Procurement Notes

Verify the specific ordering suffix ',115' corresponds to the standard tape and reel packaging configuration as defined in the official Nexperia documentation. Confirm that the product status aligns with current production requirements, as component availability and lifecycle stages may change without notice. Ensure compliance with RoHS directives and environmental regulations applicable to your region before finalizing procurement orders.

Selection Notes

Select this component when space constraints require a compact SOT-666 package while needing dual NPN switching capabilities. The integrated bias network eliminates external base resistors, reducing board area. Verify that the required collector current does not exceed 100 mA and that the operating voltage remains within the 50 V limit. Consider thermal derating if the ambient temperature exceeds 25 °C to maintain safe junction temperatures.

Part Context

This part belongs to the Nexperia PEMH series of resistor-equipped double transistors. It shares the SOT-666 footprint with other variants like PEMH15 and PEMH24 but differs in internal resistor values and transistor configurations. The '115' suffix typically denotes the specific reel packaging format used for automated surface-mount assembly processes.

Replacement Considerations

Direct pin-compatible replacements within the same family include PEMH15,115 and PEMH24,115. Substitutes must be verified against the specific R1 and R2 values required by the circuit design, as these vary across the series. Cross-family replacements require careful evaluation of pinout compatibility and electrical parameter margins.
