PEMD19,115

Overview

The PEMD19,115 is a dual pre-biased NPN/PNP digital transistor manufactured by Nexperia. It integrates two transistors with built-in bias resistors into a single SOT363 (SC-88) surface-mount package. The device features a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. Typical input resistance is 10 kΩ with a resistor ratio of 0.21. Operating temperature ranges from -65°C to +150°C. This component is designed for space-saving applications requiring logic-level switching or interface buffering.

Feature Summary

• Integrates complementary NPN and PNP transistors with internal biasing resistors in a compact footprint
• Simplifies circuit design by reducing the number of discrete components required for switching applications
• Supports high-density mounting via the small outline TSSOP-6 package

Applications

• Logic level shifting between different voltage domains
• Interface buffering for microcontroller I/O ports
• Switching applications in portable consumer electronics

Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm tape-and-reel packaging details. Ensure compliance with RoHS and REACH regulations as stated in the manufacturer's environmental declarations. Cross-reference the 12NC code for accurate ordering information.

Selection Notes

Select this component when space constraints require integrated NPN/PNP pairs with fixed biasing. Verify that the 10 kΩ typical input resistance aligns with the driving source capabilities. Confirm that the 50 V voltage rating exceeds the maximum circuit operating voltage under all conditions.

Part Context

This part belongs to the PEMD series of dual pre-biased transistors. It serves as a complement to the PUMD series, which typically offers different resistor ratios or configurations. Both series utilize the SOT363 package to provide compact solutions for digital switching tasks in modern electronic designs.

Replacement Considerations

Check for direct pin-compatible alternatives within the Nexperia PEMD family. Verify if the PUMD series variants offer suitable electrical characteristics if the specific NPN/PNP configuration allows. Ensure any substitute maintains the same SOT363 package dimensions.
