Product details
Overview
NHUMD3 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 10 kΩ base resistors per device. 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 switching and IC input control in automotive body electronics.
For engineers reviewing the NHUMD3 datasheet, NHUMD3 pinout, NHUMD3 application, or NHUMD3 equivalent, this device serves as a space- and BOM-optimized replacement for discrete BC846/BC856 pairs in level-shifting, load switching, and logic interface circuits where integrated biasing reduces layout complexity and assembly cost.
Technical Context
The NHUMD3 integrates two complementary bipolar transistors-TR1 (NPN) and TR2 (PNP)-with matched on-chip R1 = R2 = 10 kΩ base resistors, enabling direct TTL/CMOS-compatible drive without external bias components. Its dual-transistor topology supports push-pull, inverter, or complementary switching configurations in a single 6-pin SMT package.
Each transistor exhibits VCEO = 80 V, IO = 100 mA, hFE ≥ 50 (at VCE = 5 V, IC = 10 mA), and VCE(sat) ≤ 100 mV (at IC = 10 mA, IB = 0.5 mA). Thermal resistance Rth(j-a) is 358 K/W per device on FR4 PCB, supporting reliable operation in thermally constrained automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V automotive systems with margin. |
| IO | 100 mA - Continuous output current per transistor; sufficient for driving LEDs, relays, or logic inputs. |
| R1 / R2 | 10 kΩ - Integrated base resistors eliminate need for external bias components, reducing PCB area by ~30% vs. discrete pair. |
| hFE | ≥50 - DC current gain at 10 mA collector current; ensures stable saturation under typical digital drive conditions. |
| VCE(sat) | ≤100 mV - Low saturation voltage minimizes power loss and self-heating during high-duty-cycle switching. |
| AEC-Q101 | Qualified - Validated for automotive applications including engine control units, lighting modules, and body controllers. |
| Tamb | −55 °C to +150 °C - Full operational range matches under-hood and cabin temperature requirements. |
Pinout & Package
SOT363 (SC-88) plastic surface-mounted package: 6-pin, 2.2 mm × 1.35 mm footprint, 0.65 mm pitch, 0.95 mm max height; optimized for reflow soldering with standard FR4 PCB land pattern.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 (emitter of TR1) | Common emitter reference for NPN transistor; connects directly to system ground plane. |
| 2 | I1 (base input of TR1) | Logic-level input node for NPN transistor; internally pulled through 10 kΩ to GND1. |
| 3 | O2 (collector of TR2) | Active-low output terminal for PNP transistor; sinks current when TR2 is on. |
| 4 | GND2 (emitter of TR2) | Common emitter reference for PNP transistor; isolated from GND1 but typically tied together. |
| 5 | I2 (base input of TR2) | Logic-level input node for PNP transistor; internally pulled through 10 kΩ to GND2. |
| 6 | O1 (collector of TR1) | Active-high output terminal for NPN transistor; sources current when TR1 is on. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistors | Matched R1 = R2 = 10 kΩ per transistor eliminates external components and improves production yield. |
| Dual complementary topology | NPN + PNP pairing enables compact push-pull drivers or inverters without cross-coupling layout risks. |
| High VCEO rating | 80 V breakdown supports 24 V nominal systems with >2× safety margin against load dump transients. |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, humidity testing, and mechanical shock per JESD22. |
| Low VCE(sat) | ≤100 mV at 10 mA ensures <1 mW conduction loss per transistor, critical for thermal management in dense layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar resistor-equipped double transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NHUMD2 | R1 = R2 = 22 kΩ; higher input impedance; lower hFE (70 min); same VCEO/IO. | Better suited for high-impedance CMOS drive; reduced gain requires stronger input signal. | Select when interfacing with weak-drive MCUs or where lower base current consumption is prioritized. |
| NHUMD12 | R1 = R2 = 47 kΩ; highest input impedance; hFE ≥ 100; identical thermal and voltage ratings. | Optimized for ultra-low-power standby modes and battery-operated devices with minimal leakage. | Choose for energy-sensitive applications requiring <1 µA off-state input current and enhanced gain stability. |
Compared with NHUMD2 and NHUMD12, the NHUMD3 offers the lowest base resistance (10 kΩ), delivering fastest switching response and highest drive capability-ideal for medium-speed digital interfaces where speed and margin outweigh ultra-low quiescent current needs.

FAQ
What is the maximum continuous current per transistor in the NHUMD3?
The NHUMD3 supports 100 mA continuous output current per transistor (TR1 and TR2) at Tamb ≤ 25 °C with derating above that temperature. At 75 °C ambient, the rated current drops to approximately 70 mA per transistor based on the 358 K/W junction-to-ambient thermal resistance and 150 °C maximum junction temperature limit.
Can NHUMD3 be used as a direct replacement for BC846/BC856 pairs?
Yes-NHUMD3 replaces one BC846 (NPN) and one BC856 (PNP) plus their four external base resistors in a single SOT363 package. Pin compatibility requires circuit adaptation: its 6-pin layout differs from dual-SOT23 footprints, but functional equivalence is confirmed in digital switching, level translation, and load control roles per Nexperia's application guidance.
Does NHUMD3 support bidirectional signal routing?
No-it is not designed for bidirectional operation. TR1 (NPN) and TR2 (PNP) operate unidirectionally as active-high and active-low switches respectively. Their collectors (O1 and O2) serve as outputs only; no internal diode or structure enables reverse current flow or analog signal pass-through.
How does the built-in resistor ratio affect switching performance?
The NHUMD3 uses R1 = R2 = 10 kΩ, yielding a 1:1 bias ratio that ensures balanced saturation drive for both transistors. This ratio provides optimal base current for 10–100 mA loads while maintaining VI(on) ≤ 2.5 V and VI(off) ≥ 1.15 V-enabling clean logic-level transitions without external resistor tuning.
