Product details
Overview
NHUMH1X from Nexperia is an NPN/NPN resistor-equipped double transistor (RET) in SOT363 (SC-88) package, designed for digital switching and IC input control. It delivers 100 mA per transistor, supports 80 V collector-emitter breakdown voltage, integrates matched 22 kΩ base resistors (R1 = R2), and is AEC-Q101 qualified for automotive-grade reliability.
For engineers reviewing the NHUMH1X datasheet, NHUMH1X pinout, NHUMH1X application, or NHUMH1X equivalent, this device serves as a space- and cost-optimized replacement for discrete BC846-based dual-transistor circuits in logic-level interfacing, load switching, and microcontroller I/O buffering where built-in biasing simplifies layout and reduces BOM count.
Technical Context
This dual RET integrates two matched NPN transistors with monolithically embedded base resistors-R1 (input bias) and R2 (base-emitter feedback)-enabling single-resistor drive without external bias networks. Each transistor operates independently with open-base VCEO = 80 V and IO = 100 mA rating.
The device uses a common-emitter configuration per channel, with dedicated GND pins (Pin 1 and Pin 4) enabling isolated emitter referencing. Its thermal resistance Rth(j-a) is 358 K/W per device on FR4 PCB, supporting stable operation up to 150 °C junction temperature under defined derating conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Maximum safe collector-emitter voltage with base open; enables use in 24 V and 48 V industrial control rails. |
| IO | 100 mA - Continuous output current per transistor; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 / R2 | 22 kΩ / 22 kΩ - Matched integrated base resistors eliminate need for external bias components and ensure consistent turn-on behavior. |
| hFE | 70 - DC current gain at VCE = 5 V, IC = 10 mA; supports reliable saturation with low base drive current (~143 µA). |
| VCE(sat) | 100 mV - Collector-emitter saturation voltage at IC = 10 mA, IB = 0.5 mA; minimizes conduction loss in switching applications. |
| fT | 170 MHz - Transition frequency at VCE = 5 V, IC = 10 mA; supports fast digital switching up to ~10–20 MHz edge rates. |
| Ptot (device) | 350 mW - Total power dissipation at Tamb ≤ 25 °C on FR4 PCB; defines thermal design margin before derating applies. |
Pinout & Package
SOT363 (SC-88) is a 6-pin, surface-mount plastic package measuring 2.2 mm × 1.35 mm × 0.95 mm with gull-wing leads and pin 1 index marking. It supports reflow and wave soldering per IPC-7095 guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emitter terminal of transistor TR1; must be connected to system ground or local reference for TR1 operation. |
| 2 | I1 | Base input of TR1; accepts logic-level voltage (VI(on) ≈ 2.3 V typical) to activate TR1 collector output. |
| 3 | O2 | Collector output of TR2; sinks current when TR2 is active; electrically isolated from TR1's output path. |
| 4 | GND2 | Emitter terminal of transistor TR2; independent ground node allowing separate return paths or level shifting. |
| 5 | I2 | Base input of TR2; functionally identical to I1 but drives second transistor channel. |
| 6 | O1 | Collector output of TR1; provides switched output referenced to GND1; complements O2 for dual-load control. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1/R2 bias network | Eliminates 4 external resistors per dual-channel implementation, reducing PCB area by >30% vs discrete BC846 pairs. |
| AEC-Q101 qualification | Validated for automotive underhood environments including temperature cycling, humidity, and mechanical shock per JESD22 standards. |
| Matched transistor characteristics | Typical hFE variation < ±15% between TR1 and TR2 ensures balanced switching timing in synchronous applications. |
| Low VCE(sat) at 100 mA | 100 mV saturation voltage enables <10 mW conduction loss per channel at full rated current, improving efficiency in battery-powered systems. |
| SC-88 footprint compatibility | Standardized 0.65 mm pitch allows automated placement using industry-standard pick-and-place equipment without custom nozzle setup. |
Applications
| Microcontroller I/O Buffering | LED Driver Interface |
|---|---|
Use Scenario: Driving 5 V logic inputs from 3.3 V MCU GPIOs with level translation and current amplification. IC Role / Device Role / Timing Role: Dual RET acts as bidirectional signal conditioner-TR1 buffers MCU output to external logic, TR2 returns status signal to MCU input. Use Value: Built-in resistors enable direct connection without pull-up/pull-down networks; 80 V rating protects against ESD-induced transients on long traces. |
Use Scenario: Switching multiple indicator LEDs in automotive dashboard clusters with shared ground architecture. IC Role / Device Role / Timing Role: Each transistor independently controls one LED string; GND1/GND2 separation avoids ground-loop interference between channels. Use Value: 100 mA per channel supports high-brightness LEDs; 100 mV VCE(sat) limits self-heating and preserves color consistency across operating temperature range. |
| Industrial Digital Input Module | Relay Driver Stage |
Use Scenario: Conditioning 24 V dry-contact sensor signals into clean 3.3 V logic levels for PLC input cards. IC Role / Device Role / Timing Role: TR1 and TR2 serve as isolated input conditioners-one for NO, one for NC contact monitoring-with independent ground references. Use Value: 80 V VCEO withstands inductive kickback from nearby solenoids; AEC-Q101 qualification ensures long-term stability in factory-floor vibration environments. |
Use Scenario: Driving 5 V/12 V coil relays from microcontroller outputs in HVAC control panels. IC Role / Device Role / Timing Role: TR1 switches relay coil; TR2 monitors coil current via sense resistor to detect open-circuit faults. Use Value: Integrated 22 kΩ base resistors set precise IB = ~227 µA for guaranteed saturation; 350 mW total Ptot accommodates brief inrush currents during relay pull-in. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NHUMD2 | R1 = R2 = 22 kΩ (same), but packaged in SOT353 (SC-70); smaller footprint (2.1 × 1.25 mm) and lower Ptot (235 mW). | Limited to lower-power loads (<50 mA) due to reduced thermal mass; unsuitable for sustained 100 mA switching. | Select NHUMD2 only when board space is critical and peak current remains below 60 mA with adequate derating. |
| BC846BPDW1T1G | Discrete dual NPN in SOT363; no integrated resistors-requires four external 22 kΩ resistors and increases layout complexity. | Offers higher hFE (min 200) but lacks built-in biasing; demands additional validation for VI(on)/VI(off) thresholds. | Choose only if programmable base drive or adjustable gain is required; otherwise NHUMH1X reduces component count and test points. |
Compared with NHUMD2, NHUMH1X offers 49% higher power handling and identical biasing; versus BC846BPDW1T1G, it eliminates four passives and guarantees matched R1/R2 tolerance (<±10%), reducing first-pass debug time in production firmware bring-up.

FAQ
What is the maximum continuous current per transistor in NHUMH1X?
The NHUMH1X supports 100 mA continuous collector current per transistor (IO) at Tamb ≤ 25 °C with proper PCB copper area. Derating begins above 25 °C per the 350 mW device power limit curve; at 75 °C ambient, max usable current drops to ~70 mA to maintain Tj ≤ 150 °C.
Can NHUMH1X replace BC846-based circuits without layout changes?
Yes-NHUMH1X uses the same SOT363 (SC-88) footprint as BC846BDW1T1G, enabling drop-in replacement. However, external base resistors must be removed since R1 and R2 are integrated; unused resistor pads should be omitted to avoid parasitic coupling or solder bridging.
Is the GND1/GND2 separation mandatory or optional?
GND1 and GND2 are physically separate emitter terminals and must be connected to their respective circuit grounds. They are not internally tied; using a common ground defeats isolation benefits and may cause crosstalk or inaccurate sensing in differential configurations like relay fault detection.
Does NHUMH1X support 5 V logic drive directly?
Yes-its VI(on) is specified at 2.3 V (typical) with 3.3 V or 5 V CMOS/TTL outputs capable of delivering ≥0.5 mA. At 5 V drive, base current exceeds 200 µA, ensuring deep saturation even at elevated temperatures; VI(off) remains ≤0.8 V, guaranteeing clean turn-off with standard logic low levels.
