PRMD12Z

Overview

The PRMD12 is a Resistor-Equipped double Transistor (RET) containing one NPN and one PNP transistor in an ultra-small DFN1412-6 (SOT1268) leadless package. It features built-in bias resistors with a nominal value of 47 kΩ for R1 and a ratio of 1 for R2/R1. The device supports a collector-emitter voltage of 50 V, an output current of 100 mA, and a DC current gain (hFE) of 80 at 5 mA. Total power dissipation reaches 325 mW per transistor and 480 mW per device. Transition frequencies are 230 MHz for the NPN and 180 MHz for the PNP.

Feature Summary

• Integrated bias resistors simplify circuit design and reduce component count
• Ultra-thin 0.5 mm package height suitable for space-constrained applications
• Qualified for automotive applications under AEC-Q101 standards

Applications

• Digital logic applications
• Control of IC inputs
• Switching loads

Procurement Notes

Verify the specific ordering suffix to confirm packaging type, as standard distribution may vary between tape-and-reel or cut tape formats. Confirm RoHS compliance status and ensure the procurement channel provides traceability documentation required for automotive-grade components. Check for any recent product change notices that might affect marking codes or thermal characteristics.

Selection Notes

Select this RET when replacing discrete resistor-transistor networks to save board space. Ensure the 50 V rating meets the system voltage requirements. Verify that the 47 kΩ base resistance aligns with the driving source impedance. Consider the DFN1412-6 footprint dimensions during PCB layout to ensure adequate thermal relief and solder paste application.

Part Context

This component belongs to Nexperia's family of resistor-equipped double transistors designed for digital switching. It serves as a compact alternative to discrete BC847/BC857 combinations. The complementary NPN/NPN variant is designated as PRMH12. Both devices utilize the same SOT1268 package to maintain consistency in automated assembly processes.

Replacement Considerations

Direct replacements include the PRMH12 for NPN/NPN configurations. Verify pinout compatibility if substituting with other RET families. Ensure the replacement part maintains the same 47 kΩ bias resistance and 50 V breakdown voltage to prevent circuit malfunction.
