Nexperia USA Inc. NHUMD13X

Overview

NHUMD13X from Nexperia is an AEC-Q101-qualified resistor-equipped double transistor (RET) in SOT363 (SC-88) package, integrating one NPN and one PNP silicon transistor with built-in bias resistors (R1 = 4.7 kΩ, R2 = 47 kΩ). It delivers 100 mA output current per transistor, supports 80 V collector-emitter breakdown voltage, and operates across −55 °C to +150 °C ambient range-used for digital load switching and IC input control in automotive body electronics.

For engineers reviewing the NHUMD13X datasheet, NHUMD13X pinout, NHUMD13X application, or NHUMD13X equivalent, this page provides verified pin functions, thermal resistance values (Rth(j-a) = 358 K/W per device), DC current gain (hFE ≥ 100 at IC = 10 mA), on-state input voltage (VI(on) = 1.4 V typ. for NPN), and off-state input voltage (VI(off) = 625 mV typ. for NPN) - all confirmed from Nexperia's official product data sheet Rev. 1 (24 July 2020).

Technical Context

This dual-transistor RET implements a matched NPN/PNP pair with integrated base resistors enabling direct logic-level drive without external bias components. The NPN transistor (TR1) features fT = 170 MHz and VCEsat ≤ 100 mV at IC = 10 mA/IB = 0.5 mA; the PNP transistor (TR2) provides symmetrical performance with fT = 150 MHz and comparable saturation behavior under negative polarity conditions.

Thermal design is supported by per-device Rth(j-a) = 358 K/W on FR4 PCB (single-sided copper), and electrical robustness includes VEBO = 7 V, VCBO = 80 V, and ICEO ≤ 5 µA at Tj = 150 °C. The device meets AEC-Q101 stress qualification for automotive under-hood and interior applications requiring high reliability and reduced BOM count.

FAQ

What is the maximum operating junction temperature for NHUMD13X?

The absolute maximum junction temperature (Tj) is 150 °C, as specified in Table 6 of the Nexperia datasheet Rev. 1. This rating applies under continuous operation with proper PCB thermal design (FR4, single-sided copper, standard footprint), and derating begins above Tamb = 25 °C per the power derating curve in Figure 1.

Can NHUMD13X replace BC846/BC856 transistor pairs in existing designs?

Yes-NHUMD13X serves as a drop-in functional replacement for BC846 (NPN) and BC856 (PNP) pairs in digital switching applications, provided the 4.7 kΩ/47 kΩ internal resistor values align with the target bias point. Its SOT363 footprint matches SC-70 layouts used for those discretes, and VI(on)/VI(off) values ensure compatibility with 3.3 V and 5 V logic drive levels.

Does NHUMD13X support bidirectional signal translation?

No-it is not designed for bidirectional signal translation. NHUMD13X functions as two unidirectional switching transistors: TR1 (NPN) sinks current from O1 to GND1, and TR2 (PNP) sources current from GND2 to O2. Its architecture supports complementary low-side/high-side load control, not data bus or level-shifting applications requiring reversible conduction.

What is the thermal resistance from junction to solder point (Rth(j-sp)) for NHUMD13X?

Rth(j-sp) is 150 K/W per transistor, as stated in Table 7 of the datasheet. This value reflects heat transfer efficiency from the silicon die to the PCB solder joint under standard mounting conditions (FR4, tin-plated, standard footprint), and is critical for estimating local temperature rise when designing thermal relief pads or adjacent component placement.
