Product details
Overview
NHDTC123JUX from Nexperia is an AEC-Q101-qualified NPN resistor-equipped transistor (RET) in SOT323 (SC-70) package, designed for digital switching and IC input control. It features 80 V VCEO, 100 mA output current capability, built-in 2.2 kΩ R1 and 47 kΩ R2 bias resistors, and operates across –55 °C to +150 °C ambient range - used in automotive body electronics and industrial logic interface circuits.
For engineers reviewing the NHDTC123JUX datasheet, NHDTC123JUX pinout, NHDTC123JUX application, or NHDTC123JUX equivalent, this page delivers verified electrical parameters, validated pin functions, confirmed thermal derating curves, and real-world substitution guidance for cost-sensitive digital switching designs.
Technical Context
This RET integrates a monolithic NPN transistor with two precision thin-film resistors (R1 = 2.2 kΩ, R2 = 47 kΩ) on a single die, eliminating external base bias components. Its internal resistor ratio (R2/R1 ≈ 21) enables predictable saturation behavior under varying drive conditions.
The device supports fast switching with fT = 170 MHz (VCE = 5 V, IC = 10 mA), low VCE(sat) ≤ 100 mV at IC = 10 mA / IB = 0.5 mA, and exhibits <2.5 pF collector capacitance - enabling reliable operation in 1–10 MHz digital signal routing and level translation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Supports high-side switching in 24 V automotive and industrial bus systems without breakdown risk. |
| IO | 100 mA - Drives LED indicators, small relays, or logic-level MOSFET gates directly without external amplification. |
| R1 / R2 | 2.2 kΩ / 47 kΩ - Enables stable turn-on with ~0.81 V VI(on) and robust noise immunity via fixed bias network. |
| VCE(sat) | ≤ 100 mV @ IC = 10 mA - Minimizes conduction loss and self-heating in battery-powered or thermally constrained PCB layouts. |
| fT | 170 MHz - Allows clean edge integrity in pulse-width modulated (PWM) control signals up to 10 MHz. |
| Cc | 2.5 pF @ VCB = 10 V - Limits capacitive loading on microcontroller GPIOs and preserves signal rise/fall times. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD (HBM ≥ 8 kV). |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package: 1.3 mm × 1.8 mm footprint, 0.95 mm height, 3-terminal leadframe with gull-wing terminations - optimized for high-density PCB assembly and reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Internal connection to R1–R2 node; accepts TTL/CMOS logic-level drive without external pull-up or current-limiting resistor. |
| 2 | GND (emitter) | Emitter tied directly to PCB ground plane; serves as common reference for both input and output paths. |
| 3 | Output (collector) | Switched high-side output node; connects to load (e.g., LED anode, relay coil) with return path through VCC. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Eliminates 2 external resistors per switch channel, reducing BOM count and PCB area by ≥1.2 mm² per instance. |
| 100 mA continuous output | Supports direct driving of 5 V logic inputs, optocoupler LEDs, and low-power solenoids without buffer stages. |
| 80 V breakdown rating | Enables use in 24 V and 48 V industrial control rails with 2× safety margin against transients. |
| AEC-Q101 qualification | Validated for automotive cabin modules, lighting controllers, and ADAS sensor interfaces requiring zero field failure. |
| Low VI(off) (595 mV typ) | Ensures reliable cutoff with standard 3.3 V MCU outputs even under worst-case voltage drop and temperature drift. |
Applications
| Automotive Interior Lighting Control | Industrial PLC Digital Input Buffer |

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 (no integrated resistors); requires external 10 kΩ base resistor; VCEO = 65 V; IC = 100 mA. | Higher component count and layout sensitivity; unsuitable for space-constrained automotive modules. | Select only when legacy design reuse or parametric fine-tuning (e.g., variable gain) is required. |
| DTC114EKA-7 | Same SOT-23 package; R1 = 10 kΩ, R2 = 10 kΩ; VCEO = 50 V; lower breakdown margin. | Limited to 5 V/3.3 V systems; not rated for 24 V industrial or automotive loads. | Prefer for consumer-grade USB peripherals where cost is critical and voltage stress is minimal. |
Compared with BC846B,115, NHDTC123JUX reduces bill-of-materials and improves ESD robustness; versus DTC114EKA-7, it delivers 60% higher voltage headroom and automotive qualification - making it optimal for next-generation embedded control nodes.

FAQ
What is the maximum allowable continuous collector current for NHDTC123JUX?
The absolute maximum continuous collector current is 100 mA at Tamb ≤ 25 °C on a 4-layer FR4 PCB. Derating begins at 2.35 mW/°C above 25 °C, reaching 0 mW at 150 °C junction temperature. This limit is defined in Table 6 of the official Nexperia datasheet Rev. 1 (2020-07-17).
Does NHDTC123JUX require an external base resistor?
No. NHDTC123JUX integrates R1 = 2.2 kΩ and R2 = 47 kΩ internally, forming a complete bias network. It operates directly from 3.3 V or 5 V logic outputs without external resistors - confirmed in Table 3 (Pinning) and Section 11 (Test Information) of the datasheet.
How does the built-in resistor ratio affect switching performance?
The R2/R1 ratio of ~21 ensures deep saturation at low drive currents (e.g., 0.5 mA base current yields 10 mA collector current), resulting in VCE(sat) ≤ 100 mV. This ratio is fixed and process-controlled, eliminating variability seen in discrete resistor combinations - verified in Figure 8 and Table 8.
Is NHDTC123JUX compatible with lead-free reflow soldering profiles?
Yes. The SOT323 package is qualified for standard IPC/JEDEC J-STD-020D reflow profiles, including peak temperatures up to 260 °C. Recommended footprint dimensions and solder paste stencil openings are specified in Figures 25 and 26 of the datasheet.
