Overview
The PEMH4,115 is a dual NPN resistor-equipped transistor (RET) housed in an ultra-small SOT666 surface-mounted package. It integrates two independent NPN transistors with built-in bias resistors, where R1 is typically 10 kΩ and R2 remains open. The device supports a collector-emitter voltage of 50 V and a continuous output current of 100 mA per transistor. Total power dissipation reaches 300 mW for the device at 25 °C ambient temperature. The component operates within a junction temperature range up to 150 °C and features a thermal resistance from junction to ambient of 416 K/W when mounted on an FR4 PCB.
Feature Summary
- Built-in bias resistors simplify circuit design by reducing external component count
- Ultra-small SOT666 package reduces pick and place costs and saves PCB area
- Dual configuration provides two independent NPN transistors in a single unit
Applications
- Low current peripheral driver
- Replacement of general purpose transistors in digital applications
- Control of IC inputs
Procurement Notes
Verify the specific ordering suffix
Selection Notes
Select this component for designs requiring compact dual NPN switching with integrated base resistors. Ensure the 50 V collector-emitter rating and 100 mA current limit meet the load requirements. Verify that the application does not require automotive qualification, as this specific part number is designated for non-automotive use only.
Part Context
This device belongs to Nexperia's Resistor-Equipped Transistor (RET) family, designed to replace discrete transistor-resistor combinations. It serves as the NPN/NPN complement to the PEMD4 PNP/PNP variant. The SOT666 package allows for high-density mounting compared to standard dual-transistor packages.
Replacement Considerations
Direct functional replacements include other dual NPN RETs in SOT666 packages with similar 50 V ratings and 10 kΩ input resistors. Verify pin compatibility and thermal characteristics before substitution.
FAQ
