Nexperia USA Inc. PRMH10Z

Overview

PRMH10Z from Nexperia is an NPN/NPN resistor-equipped double transistor (RET) in a DFN1412-6 (SOT1268) package, designed for digital switching and IC input control. It features 50 V V_CEO, 100 mA output current per transistor, built-in bias resistors (R1 = 2.2 kΩ typ, R2/R1 = 21 typ), and AEC-Q101 qualification for automotive use.

For engineers reviewing the PRMH10Z datasheet, PRMH10Z pinout, PRMH10Z application, or PRMH10Z equivalent, this device serves as a space- and cost-optimized replacement for discrete BC847/BC857 pairs in low-voltage logic interfacing, load switching, and automotive body electronics where board area and assembly count are critical.

Technical Context

This dual NPN RET integrates two matched transistors with monolithically embedded base bias networks-R1 connected between base and emitter, R2 between base and input-enabling single-resistor drive without external bias components. Each transistor operates independently with isolated emitters (GND1, GND2) and collectors (O1, O2).

The DFN1412-6 package provides thermal enhancement (R_th(j-a) = 261 K/W per device on FR4) and ultra-low profile (0.47 mm height), supporting high-density routing and reflow-compatible assembly. Its AEC-Q101 qualification confirms suitability for under-hood and cabin control modules.

Key Specifications

Pinout & Package

PRMH10Z is housed in a leadless DFN1412-6 (SOT1268) package measuring 1.4 mm × 1.2 mm × 0.47 mm, with exposed thermal pad and 6 terminals arranged in a 2×3 layout. The package supports automated optical inspection (AOI) and offers 261 K/W thermal resistance to ambient on standard FR4.

FAQ

What is the maximum operating temperature for PRMH10Z?

The PRMH10Z has a maximum junction temperature (T_j) of 150 °C and is rated for ambient temperatures from −55 °C to 150 °C. Its AEC-Q101 qualification confirms reliability under sustained thermal stress in automotive under-hood environments, provided PCB layout maintains thermal resistance below 261 K/W per device.

Can PRMH10Z replace BC847/BC857 pairs in existing designs?

Yes-PRMH10Z is explicitly positioned as a cost- and space-saving alternative to BC847/BC857 series in digital applications. It replicates the dual-NPN switching function with integrated biasing, eliminating four external resistors and two transistors. Pin mapping differs, so PCB layout revision is required, but schematic logic remains identical.

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

No-the thermal pad on the underside of the DFN1412-6 package is not electrically connected to any internal node. It is intended solely for thermal conduction to the PCB copper pour and must be soldered to a dedicated thermal land with appropriate stencil aperture and solder paste volume per Nexperia's reflow footprint guidelines (Fig. 12).

How does the R2/R1 ratio affect switching performance?

The R2/R1 ratio of 21 typ determines the effective base current and thus the saturation depth of each transistor. A higher ratio increases noise immunity and reduces sensitivity to input leakage but slightly raises VI(on). At 21, PRMH10Z achieves optimal balance: guaranteed turn-on with 3.3 V logic while maintaining fast fall times (<50 ns) and low V_CE(sat).
