Product details
Overview
NHUMH11 from Nexperia is an AEC-Q101-qualified NPN/NPN resistor-equipped double transistor (RET) in SOT363 (SC-88) package, rated for 80 V VCEO, 100 mA output current per transistor, and featuring integrated 10 kΩ input bias resistors (R1 = R2 = 10 kΩ). It functions as a dual-channel digital switch for controlling IC inputs or low-power loads in space-constrained automotive and industrial control modules.
For engineers reviewing the NHUMH11 datasheet, NHUMH11 pinout, NHUMH11 application, or NHUMH11 equivalent, this device serves as a drop-in replacement for BC846-based dual-switch circuits-offering reduced BOM count, simplified layout, and guaranteed automotive-grade reliability without external base resistors.
Technical Context
The NHUMH11 integrates two matched NPN transistors with monolithically embedded 10 kΩ base-emitter pull-down resistors (R1) and 10 kΩ base-input resistors (R2), enabling direct logic-level drive from 3.3 V or 5 V microcontrollers. Its dual-transistor topology supports independent switching of two signal paths with shared ground reference.
Designed for digital switching-not linear amplification-it exhibits VCE(sat) ≤ 100 mV at IC = 10 mA / IB = 0.5 mA, VI(on) = 1.8–2.5 V, and VI(off) = 0.8–1.15 V, ensuring robust noise immunity and clean turn-on/turn-off behavior in noisy environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Supports operation in 24 V automotive supply rails with margin against load-dump transients. |
| IO | 100 mA per transistor - Drives LED indicators, small relays, or logic inputs without external current boosting. |
| R1 / R2 | 10 kΩ each - Eliminates need for four discrete base resistors; sets standard logic-compatible input impedance. |
| VCE(sat) | ≤ 100 mV @ IC = 10 mA - Minimizes power loss and self-heating during sustained on-state operation. |
| AEC-Q101 | Qualified - Validated for automotive underhood applications including temperature cycling, humidity, and mechanical shock. |
| Ptot (device) | 350 mW @ Tamb ≤ 25 °C - Enables dual-switch operation within thermal limits on standard FR4 PCBs. |
| hFE | 50 min @ VCE = 5 V, IC = 10 mA - Ensures sufficient current gain for reliable saturation with standard MCU GPIO drive. |
Pinout & Package
SOT363 (SC-88) 6-pin surface-mount plastic package: 2.2 mm × 1.35 mm footprint, 0.65 mm pitch, 0.95 mm max height; optimized for reflow soldering with defined solder paste land pattern (Fig. 24).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 (emitter TR1) | Common emitter reference for first transistor; connects to system ground plane for low-inductance return path. |
| 2 | I1 (base TR1) | Logic-input node with built-in R2 = 10 kΩ series resistor; accepts 3.3 V/5 V CMOS/TTL directly. |
| 3 | O2 (collector TR2) | Active-low switched output for second channel; sinks up to 100 mA when TR2 is saturated. |
| 4 | GND2 (emitter TR2) | Independent emitter terminal for second transistor; allows separate grounding or current sensing. |
| 5 | I2 (base TR2) | Second logic-input node with identical R2 = 10 kΩ; enables synchronous or independent dual-channel control. |
| 6 | O1 (collector TR1) | First active-low switched output; electrically isolated from O2 but shares thermal substrate in same die. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET topology | Two fully independent switching channels in one SC-88 package-reduces board area by >40% vs. discrete BC846 pairs. |
| Integrated bias network | Matched R1 = R2 = 10 kΩ per channel eliminates four external resistors and associated placement errors. |
| Automotive qualification | AEC-Q101 certified for -55 °C to +150 °C operation-validates use in engine control, body electronics, and ADAS sensors. |
| Low VCE(sat) | ≤100 mV ensures <10 mW conduction loss per channel at 100 mA-critical for thermally constrained modules. |
| High VCEO | 80 V rating supports 24 V systems with 3× safety margin over ISO 7637-2 pulse 5a (58 V peak), reducing need for TVS clamping. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Output |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC846BPDW1T3G | Discrete dual NPN in SOT-363; no built-in resistors-requires 4 external 10 kΩ resistors. | Higher BOM count and layout complexity; lacks AEC-Q101 qualification. | Select only if legacy design reuse or resistor value customization is required. |
| NHUMD3 | PNP/PNP complement with same 10 kΩ R1/R2 values; identical SOT363 package and pinout. | Used for high-side switching or complementary logic where sourcing current is needed. | Choose when driving loads referenced to VCC instead of ground, or building push-pull outputs. |
Compared with BC846BPDW1T3G, NHUMH11 reduces bill-of-materials and assembly steps while adding automotive qualification; versus NHUMD3, it provides NPN/NPN topology for low-side switching-making it optimal for ground-referenced loads in 24 V systems.

FAQ
What is the maximum operating temperature for NHUMH11?
The NHUMH11 has a specified junction temperature limit of 150 °C and an ambient operating range of −55 °C to +150 °C. Its thermal resistance from junction to ambient is 358 K/W (per device on FR4 PCB), allowing continuous 100 mA operation at up to +85 °C ambient when properly heatsinked via copper pour.
Can NHUMH11 be used with 3.3 V microcontrollers?
Yes. The NHUMH11's VI(on) is guaranteed ≤2.5 V and VI(off) ≥0.8 V at 25 °C, ensuring full saturation with 3.3 V logic levels. Its 10 kΩ input resistor provides ~330 µA base drive at 3.3 V-sufficient for hFE ≥50 and IC = 100 mA, with margin across temperature.
How does NHUMH11 differ from NHUMH1 and NHUMH2?
NHUMH11 uses 10 kΩ R1/R2 bias resistors, NHUMH1 uses 22 kΩ, and NHUMH2 uses 47 kΩ. This changes input current requirements and noise immunity: NHUMH11 draws highest input current (ideal for fast switching), NHUMH2 offers lowest power consumption and best noise rejection at slower edges.
Is NHUMH11 pin-compatible with other SOT363 dual transistors?
Yes-NHUMH11 follows JEITA SC-88 standard pinout (GND1-I1-O2-GND2-I2-O1), matching BC846BPDW1T3G, MMBT3904DW, and NHUMD3. However, electrical behavior differs due to integrated resistors; direct substitution requires verifying input drive capability and load requirements.
