Nexperia USA Inc. PRMD2Z

Overview

PRMD2Z from Nexperia is an AEC-Q101-qualified NPN/PNP resistor-equipped double transistor (RET) in a DFN1412-6 (SOT1268) package, delivering 50 V V_CEO, 100 mA output current per transistor, and integrated bias resistors (R1 = 22 kΩ, R2/R1 = 1.0). It serves as a space- and cost-optimized digital switching element for automotive and industrial control circuits requiring dual-polarity load switching with reduced external component count.

For engineers reviewing the PRMD2Z datasheet, PRMD2Z pinout, PRMD2Z application, or PRMD2Z equivalent, this device offers verified dual-transistor functionality with built-in biasing, ultra-thin 0.47 mm profile, thermal resistance of 261 K/W (per device), and qualification for automotive ambient conditions up to 150 °C.

Technical Context

The PRMD2Z integrates one NPN and one PNP transistor sharing common ground terminals (Pin 1 and Pin 4), each with dedicated base inputs (Pins 2 and 5) and collector outputs (Pins 6/7 and Pins 3/8). Its internal resistor network (R1 ≈ 22 kΩ, R2/R1 = 0.8–1.2) enables direct logic-level drive without external biasing components.

It operates across –55 °C to +150 °C ambient, supports 325 mW per transistor and 480 mW total device power dissipation on FR4 PCB, and delivers h_FE ≥ 60 at I_C = 5 mA, V_CE = 5 V - enabling reliable saturation switching at low base currents (e.g., 0.5 mA for 10 mA I_C).

FAQ

What is the maximum operating temperature for PRMD2Z in continuous use?

The PRMD2Z is rated for continuous operation up to +150 °C junction temperature and –55 °C to +150 °C ambient temperature. On a standard FR4 PCB with single-sided copper, its thermal resistance is 261 K/W (per device), allowing full 100 mA dual-channel operation at ambient ≤85 °C without derating.

Can PRMD2Z replace BC847/BC857 transistor pairs directly?

Yes - PRMD2Z provides functional equivalence to a matched BC847 (NPN) + BC857 (PNP) pair with integrated bias resistors. It uses the same DFN1412-6 footprint and matches key parameters: V_CEO = 50 V, I_O = 100 mA, h_FE ≥ 60. No layout change is needed beyond removing four external resistors.

How does the built-in R2/R1 ratio affect switching behavior?

The R2/R1 ratio of 0.8–1.2 ensures consistent base current division, resulting in predictable VI(on) (2.5 V typ) and VI(off) (1.1 V typ) thresholds. This stabilizes logic compatibility across temperature (–40 °C to +125 °C) and eliminates variability from hand-selected discrete resistors.

Is the thermal pad on the DFN1412-6 package electrically connected?

No - the exposed copper pad on the underside of the DFN1412-6 (SOT1268) package is a thermal enhancement feature only and is not electrically connected to any internal circuit node. It must be soldered to a thermal land on the PCB for optimal heat dissipation but should remain floating or tied to GND only if explicitly required by system grounding strategy.
