PEMD48,115

Overview

The PEMD48,115 is a dual Resistor-Equipped Transistor (RET) containing an NPN transistor (TR1) and a PNP transistor (TR2) in a SOT666 package. It features built-in bias resistors: TR1 has R1 = 47 kΩ and R2 = 47 kΩ; TR2 has R1 = 2.2 kΩ and R2 = 47 kΩ. The device supports a collector-emitter voltage of 50 V and an output current of 100 mA per transistor. Total power dissipation is 300 mW at 25 °C ambient temperature. Transition frequencies are typically 230 MHz for the NPN and 180 MHz for the PNP.

Feature Summary

• Integrates NPN and PNP transistors with fixed internal bias resistors to reduce component count.
• Provides simplified circuit design by eliminating external base drive components.
• Offers a compact SOT666 surface-mount package suitable for high-density layouts.

Applications

• Low current peripheral driver circuits
• Controlling IC inputs
• Replacement for general purpose transistors in digital applications

Procurement Notes

Verify that the specific application does not require automotive qualification, as this product data sheet explicitly states the product is non-automotive qualified. Confirm thermal management requirements against the 300 mW total power dissipation limit at 25 °C ambient temperature. Ensure PCB footprint matches the SOT666 dimensions provided in the datasheet.

Selection Notes

Select this component when a complementary NPN/PNP pair with integrated biasing is required. The NPN section is suited for higher impedance inputs due to its 47 kΩ resistor, while the PNP section's 2.2 kΩ resistor provides stronger drive capability. Verify that the 50 V breakdown voltage meets the system's maximum operating conditions.

Part Context

The PEMD48 belongs to Nexperia's family of Resistor-Equipped Double Transistors. It replaces discrete transistor and resistor combinations, saving printed circuit board area. This specific variant combines an NPN with a 47 kΩ input resistor and a PNP with a 2.2 kΩ input resistor within a single SOT666 package.
