Overview
The Nexperia PEMD24 is a Resistor-Equipped Double Transistor (RET) featuring one NPN and one PNP transistor in an SOT666 surface-mounted package. It provides a collector-emitter voltage of 50 V and an output current of 20 mA per transistor. The device includes built-in bias resistors with a typical value of 100 kΩ for R1 and a ratio of 1 for R2/R1. Total power dissipation is rated at 300 mW, with a maximum junction temperature of 150 °C. The component operates within an ambient temperature range of -65 °C to 150 °C.
Feature Summary
- Integrates NPN and PNP transistors with built-in bias resistors to simplify circuit design
- Reduces component count and pick-and-place costs through dual-transistor integration
- Provides compact SOT666 packaging for space-constrained applications
Applications
- Low current peripheral driver
- Control of IC inputs
- Replaces general-purpose transistors in digital applications
Procurement Notes
Verify the specific ordering suffix and package variant against the official Nexperia datasheet before procurement. Confirm that the product status aligns with current production requirements, as specifications may change. Ensure compliance with RoHS and REACH regulations relevant to your region. Cross-reference the marking code '6N' for identification during assembly inspection.
Selection Notes
Select this component when designing circuits requiring both NPN and PNP switching capabilities in a minimal footprint. The integrated 100 kΩ bias resistors eliminate external resistor placement, reducing board space. Verify that the 20 mA output current and 50 V voltage ratings meet the load requirements. Consider the thermal resistance characteristics if operating near the upper temperature limits.
Part Context
The PEMD24 belongs to Nexperia's family of Resistor-Equipped Transistors (RETs). It serves as a complement to the PEMB24, which features a PNP/PNP configuration. This series is designed to replace multiple discrete components, offering a streamlined solution for digital logic interfacing and low-power switching tasks in consumer and industrial electronics.
Replacement Considerations
The PEMB24 is the documented PNP/PNP complement within the same series. No other direct substitute part numbers are confirmed in the provided documentation.
