Nexperia USA Inc. NHUMD2F

Overview

NHUMD2F from Nexperia is a resistor-equipped double transistor (RET) in SOT363 (SC-88) package, integrating one NPN and one PNP bipolar junction transistor with built-in bias resistors (R1 = R2 = 22 kΩ). It delivers 100 mA output current per transistor, supports 80 V collector-emitter breakdown voltage, and is AEC-Q101 qualified for automotive digital switching applications.

For engineers reviewing the NHUMD2F datasheet, NHUMD2F pinout, NHUMD2F application, or NHUMD2F equivalent, this device serves as a space- and cost-optimized replacement for discrete BC846/BC856 pairs in level-shifting, load switching, and IC input control circuits where simplified BOM and reduced PCB footprint are critical.

Technical Context

The NHUMD2F integrates two complementary transistors - TR1 (NPN) and TR2 (PNP) - each with monolithically embedded base bias resistors (R1 = R2 = 22 kΩ), eliminating external pull-up/pull-down components. Its dual-transistor topology enables push-pull or complementary switching without inter-device matching concerns.

It operates across –55 °C to +150 °C ambient, supports 100 mA continuous output per channel, and features low VCEsat (≤100 mV at IC = 10 mA, IB = 0.5 mA) and high DC current gain (hFE = 70 min at VCE = 5 V, IC = 10 mA for TR1). Input voltage limits are asymmetric: TR1 accepts –10 V to +60 V; TR2 accepts –60 V to +10 V.

FAQ

What is the maximum safe operating voltage for NHUMD2F's input pins?

The absolute maximum input voltage for TR1 (pin 2) is –10 V to +60 V; for TR2 (pin 5), it is –60 V to +10 V. These ratings are defined in Table 6 (Limiting Values) and reflect the built-in resistor network's voltage division and transistor junction limits. Exceeding either bound risks permanent damage to the internal resistors or base-emitter junctions.

Can NHUMD2F replace two discrete BC846/BC856 transistors in a push-pull configuration?

Yes - NHUMD2F is explicitly positioned as a cost- and space-saving alternative to BC846/BC856 pairs in digital switching. Its integrated 22 kΩ bias resistors match typical BC846 base-drive requirements, and its complementary NPN/PNP topology supports true push-pull operation without external bias components or layout matching concerns.

Is thermal derating required for NHUMD2F at elevated ambient temperatures?

Yes - total device power dissipation must be derated above Tamb = 25 °C. Per Figure 1, Ptot drops linearly from 350 mW at 25 °C to 0 mW at ~175 °C. At 100 °C ambient, maximum allowable power is ~175 mW. Designers must calculate worst-case I_C × V_CE and apply this curve to ensure junction temperature stays below 150 °C.

Does NHUMD2F support bidirectional signal routing or analog amplification?

No - NHUMD2F is designed exclusively for digital switching. Its built-in resistors fix base biasing, and its hFE variation (70–200) and frequency response (f_T = 170 MHz for TR1) are specified only under switching conditions. It lacks linear-region characterization, AC small-signal parameters, or guaranteed analog performance and is not intended for amplifier or bidirectional analog switch use.
