Product details
Overview
NHDTC123JUF from Nexperia is an AEC-Q101-qualified NPN resistor-equipped transistor (RET) in SOT323 (SC-70) package, designed for digital switching with 80 V VCEO, 100 mA IO, and built-in 2.2 kΩ/47 kΩ bias resistors. It replaces discrete BJT + base-resistor combinations in load control, IC input conditioning, and automotive body electronics.
For engineers reviewing the NHDTC123JUF datasheet, NHDTC123JUF pinout, NHDTC123JUF application, or NHDTC123JUF equivalent, this page delivers verified electrical specs, thermal derating curves, input/output voltage thresholds across temperature, and direct alternatives for cost-sensitive digital interface designs.
Technical Context
This RET integrates a silicon NPN transistor with two precision laser-trimmed on-die resistors: R1 (2.2 kΩ) connected between base and input, and R2 (47 kΩ) from base to emitter. The internal topology enables single-pin digital drive without external bias components.
It operates as a saturated switch under standard logic-level inputs: VI(on) = 0.81 V (typ) at IC = 10 mA ensures reliable turn-on from 1.2–1.8 V sources, while VI(off) = 0.595 V (typ) guarantees robust noise immunity below 0.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Supports switching of 24 V industrial loads or 48 V telecom rails with 2× safety margin. |
| IO | 100 mA - Drives LED strings, small relays, or logic-level MOSFET gates without external amplification. |
| R1 / R2 | 2.2 kΩ / 47 kΩ - Sets precise base current ratio (R2/R1 ≈ 21), enabling predictable saturation and fast turn-off. |
| VCE(sat) | 100 mV (max) at IC = 10 mA, IB = 0.5 mA - Minimizes conduction loss in battery-powered or thermally constrained PCBs. |
| Ptot | 315 mW (4-layer FR4) - Enables continuous operation up to 85 °C ambient when mounted on standard 4-layer boards. |
| fT | 170 MHz - Ensures clean switching edges for PWM frequencies up to 10 MHz with minimal delay. |
| AEC-Q101 | Qualified - Validated for automotive cabin modules, lighting controls, and power distribution units per stress test requirements. |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package: 1.35 mm × 1.15 mm × 0.45 mm footprint with gull-wing leads; optimized for reflow soldering per IPC-7351B (land pattern: 0.55 mm pad width, 2.65 mm × 2.35 mm overall).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base via R1) | Logic-level signal entry point; internal 2.2 kΩ resistor limits base current and eliminates need for external pull-up/down. |
| 2 | GND (emitter) | Emitter tied directly to ground reference; provides low-impedance return path for load current and simplifies PCB routing. |
| 3 | Output (collector) | Switched high-side output node; connects to load (e.g., LED anode or relay coil) with 80 V blocking capability. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Eliminates 2 external resistors, reducing BOM count and placement cost by ~$0.008/unit at volume. |
| Low VI(on) threshold | 0.81 V (typ) enables direct interface with 1.2 V/1.8 V microcontrollers without level-shifting circuitry. |
| High VCEO rating | 80 V withstand allows use in 24 V CAN bus nodes, solenoid drivers, and industrial PLC I/O modules. |
| Thermal robustness | Rth(j-a) = 397 K/W on 4-layer FR4 supports >85 °C ambient operation in sealed enclosures. |
| AEC-Q101 qualification | Validated for automotive Grade 2 (-40 °C to +105 °C) applications including seat control and HVAC actuators. |
Applications
| Automotive Body Control | Industrial Sensor Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC846B,115 | Discrete NPN BJT requiring external 10 kΩ base resistor; no integrated R2, higher layout sensitivity. | Lacks AEC-Q101 qualification; suitable only for commercial-grade consumer products. | Select when cost-per-unit is prioritized over design cycle time and automotive compliance. |
| DTC114EKA-7 | Same SOT323 package but R1/R2 = 10 kΩ/10 kΩ; higher VI(on) = 0.95 V (typ), lower gain consistency. | Optimized for 5 V logic systems; less suitable for sub-2 V MCU interfaces. | Choose for legacy 5 V designs where existing R1/R2 ratio matches and thermal margin is less critical. |
Compared with BC846B,115, NHDTC123JUF reduces component count and improves ESD robustness; versus DTC114EKA-7, it delivers lower VI(on) and tighter R1 tolerance for stable switching in low-voltage embedded systems.

FAQ
What is the maximum allowable input voltage (VI) for NHDTC123JUF?
The absolute maximum input voltage is +20 V, as specified in Table 6. Operation above this level risks permanent damage to the integrated R1 resistor and base-emitter junction. For reliable 3.3 V or 5 V logic interfacing, VI remains well within safe operating range with margin.
Does NHDTC123JUF require an external pull-down resistor on the input pin?
No. The internal R2 (47 kΩ) resistor from base to emitter provides inherent pull-down functionality, ensuring the transistor stays off during MCU reset or floating input conditions without additional components.
How does thermal performance differ between single-sided and 4-layer PCB mounting?
On a 4-layer FR4 board, Rth(j-a) is 397 K/W, enabling 315 mW total power dissipation at 25 °C ambient. On single-sided copper, Rth(j-a) rises to 532 K/W, limiting Ptot to 235 mW - a 25% reduction requiring derating above 60 °C ambient.
Can NHDTC123JUF replace BC846 in existing designs without layout changes?
Yes - both use SOT323 (SC-70) packages with identical pinout (1=base, 2=emitter, 3=collector). However, BC846 requires external base resistors, so the NHDTC123JUF implementation removes those footprints and may require minor netlist updates to connect input directly to Pin 1.
