Nexperia USA Inc. NHUMD2X

Overview

NHUMD2X 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 22 kΩ base resistors (R1 = R2). It delivers 100 mA output current per transistor, supports 80 V collector-emitter breakdown voltage, and functions as a compact, dual-polarity switching element for digital logic interfacing and load control in space-constrained automotive and industrial PCBs.

For engineers reviewing the NHUMD2X datasheet, NHUMD2X pinout, NHUMD2X application, or NHUMD2X equivalent, this page provides verified technical context, validated pin-level circuit roles, confirmed thermal and switching specifications, and real-world substitution guidance - all grounded in Nexperia's official Rev. 1 product data sheet dated 24 July 2020.

Technical Context

The NHUMD2X implements a monolithic dual-transistor architecture with matched NPN and PNP devices sharing a common substrate, each equipped with precision-trimmed 22 kΩ input bias resistors (R1 and R2) and fixed R2/R1 = 1 ratio. Its complementary polarity enables push-pull or level-shifting configurations without external bias networks.

It operates across –55 °C to +150 °C ambient, supports 100 mA continuous output per transistor, and maintains stable DC current gain (h_FE = 70 min at V_CE = 5 V, I_C = 10 mA) and low V_CE(sat) ≤ 100 mV under I_C/I_B = 20 drive - enabling efficient on-state conduction in digital switching applications.

FAQ

What is the maximum operating junction temperature for NHUMD2X?

The absolute maximum junction temperature (T_j) is 150 °C, as specified in Table 6 of the Nexperia datasheet. Derating begins above 25 °C ambient, with total device power dissipation limited to 350 mW at T_amb ≤ 25 °C on FR4 PCB - corresponding to a thermal resistance R_th(j-a) of 358 K/W per device.

Can NHUMD2X replace BC846/BC856 transistor pairs in existing designs?

Yes - NHUMD2X is explicitly positioned as a cost-saving alternative to BC846/BC856 pairs in digital applications. Its integrated 22 kΩ resistors, matched NPN/PNP characteristics, and SOT363 footprint enable direct drop-in replacement with no layout change, reducing component count by four passive parts and improving thermal tracking between transistors.

How does the dual-emitter isolation (GND1 vs. GND2) benefit circuit design?

GND1 and GND2 are electrically isolated terminals, allowing independent grounding of the NPN and PNP emitters. This enables floating bias configurations, level-shifting between non-common reference domains, and implementation of isolated push-pull or complementary output stages - critical in isolated power supplies and medical sensor interfaces where ground separation is required.

Is NHUMD2X suitable for PWM-driven loads like fans or solenoids?

Yes - with f_T = 170 MHz (NPN) and 150 MHz (PNP), V_CE(sat) ≤ 100 mV, and 100 mA continuous rating, NHUMD2X supports clean switching up to 100 kHz PWM frequencies. Its low saturation voltage minimizes power loss (<10 mW at full load), and AEC-Q101 qualification ensures reliability under repetitive thermal cycling in motor-control applications.
