Product details
Overview
NHDTC114EUX from Nexperia is an 80 V, 100 mA NPN resistor-equipped transistor (RET) in SOT323 (SC-70) package, integrating 10 kΩ input and 10 kΩ base-emitter bias resistors. It functions as a single-chip digital switch for IC input control and load switching, with VCEO = 80 V, IO = 100 mA, and VCE(sat) ≤ 100 mV at IC = 10 mA / IB = 0.5 mA.
For engineers reviewing the NHDTC114EUX datasheet, NHDTC114EUX pinout, NHDTC114EUX application, or NHDTC114EUX equivalent, this part serves as a space- and BOM-optimized replacement for BC846-series discrete transistor + resistor combinations in low-power digital logic interfacing and microcontroller I/O buffering.
Technical Context
This RET integrates a monolithic NPN transistor with two precision on-die resistors (R1 = R2 = 10 kΩ ±30%) to form a fixed-current-biased switch. Its internal structure eliminates external base resistors while maintaining predictable VI(on) = 1.8–2.5 V and VI(off) = 0.8–1.15 V thresholds across temperature.
The device operates with open-base collector-emitter breakdown of 80 V and supports continuous output current up to 100 mA. Thermal resistance Rth(j-a) is 532 K/W on single-sided FR4 PCB, enabling reliable operation up to 150 °C junction temperature under defined layout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V and 48 V industrial control rails. |
| IO | 100 mA - Continuous DC output current capability; sufficient for driving LEDs, small relays, and logic inputs. |
| VCE(sat) | ≤100 mV at IC=10 mA/IB=0.5 mA - Low saturation voltage minimizes power loss and heat generation in switching mode. |
| R1 / R2 | 10 kΩ / 10 kΩ - Matched on-die bias resistors simplify PCB layout and eliminate two external components per switch node. |
| hFE | 50 min at VCE=5 V, IC=10 mA - Guaranteed DC current gain ensures robust turn-on margin with standard MCU GPIO drive. |
| fT | 170 MHz - Transition frequency of internal transistor supports fast edge response in digital switching applications. |
| Ptot | 235 mW (FR4, single-layer) - Total power dissipation limit defines thermal design envelope for compact layouts. |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package: 1.35 mm × 1.15 mm × 0.45 mm body, 3-terminal leadframe, JEDEC-compliant footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Internal connection to R1; accepts TTL/CMOS-compatible logic-level drive without external series resistor. |
| 2 | GND (emitter) | Emitter tied directly to PCB ground plane; serves as common reference for input and output paths. |
| 3 | Output (collector) | Switched high-side output node; connects to load (e.g., LED anode, relay coil, logic input) referenced to VCC. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated dual-resistor topology | Eliminates two external resistors per switch, reducing PCB area by ≥1.5 mm² and assembly cost per node. |
| 80 V VCEO rating | Supports direct interface with 24 V PLC I/O, automotive body electronics, and industrial sensor signal conditioning. |
| 100 mA continuous output | Drives standard indicator LEDs (20 mA), optocoupler inputs (10–20 mA), and CMOS/TTL fan-out loads without buffering. |
| VI(on)/VI(off) thresholds | Guaranteed 1.8–2.5 V turn-on and 0.8–1.15 V turn-off voltages enable clean logic-level translation from 3.3 V and 5 V MCUs. |
Applications
| Industrial Digital I/O | Microcontroller GPIO Buffering |
|---|---|
|
Use Scenario: Isolating and level-shifting PLC output signals to 24 V field devices. IC Role / Device Role / Timing Role: NPN RET acts as a unidirectional, current-sinking digital switch between controller logic and solenoid/relay driver stage. Use Value: Replaces BC846 + two 10 kΩ resistors, cutting BOM count by 3 parts and improving production yield on dense I/O modules. |
Use Scenario: Protecting 3.3 V MCU GPIO pins from overcurrent when driving capacitive or inductive loads. IC Role / Device Role / Timing Role: Acts as a hardened, resistor-biased buffer that limits base current and absorbs transient energy during switching. Use Value: Prevents GPIO latch-up and reduces ESD-induced failures in handheld and IoT edge nodes without adding discrete protection circuitry. |
| LED Indicator Control | Logic-Level Translation |
|
Use Scenario: Driving status LEDs on embedded boards where space and component count are constrained. IC Role / Device Role / Timing Role: Functions as a constant-current sink switch with built-in bias network for stable LED brightness control. Use Value: Enables direct MCU-to-LED connection with no external resistor needed-reducing bill-of-materials and eliminating tolerance drift in LED current. |
Use Scenario: Converting 5 V logic outputs to 3.3 V compatible inputs in mixed-voltage systems. IC Role / Device Role / Timing Role: Provides active-low level shifting via emitter-follower configuration with fixed VI(on)/VI(off) thresholds. Use Value: Delivers deterministic switching thresholds (1.8–2.5 V) independent of load capacitance, ensuring timing integrity in clock distribution and bus enable paths. |
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 transistor only; requires external 10 kΩ base resistor and 10 kΩ base-emitter pull-down. | Higher BOM count and larger PCB footprint; less immune to layout-induced noise coupling on base node. | Select when legacy designs mandate discrete transistors or when bias resistor values must be user-adjustable. |
| NHDTC124EUX | Same SOT323 package but with 22 kΩ/22 kΩ bias resistors; higher VI(on) (2.3–3.0 V) and lower hFE (70 min). | Better suited for 5 V logic systems with higher noise margins; reduced sensitivity to leakage currents in high-temperature environments. | Select when interfacing with 5 V microcontrollers or when tighter off-state leakage (<270 µA) is required at elevated ambient temperatures. |
Compared with BC846B,115, NHDTC114EUX reduces component count and improves layout robustness; compared with NHDTC124EUX, it offers lower VI(on) and higher hFE, making it optimal for 3.3 V MCU-driven digital switching where fast turn-on and strong drive margin are critical.

FAQ
What is the maximum operating temperature for NHDTC114EUX?
The junction temperature (Tj) must not exceed 150 °C under any operating condition. Ambient temperature range is –55 °C to +150 °C, with thermal resistance Rth(j-a) = 532 K/W on single-layer FR4 PCB. Derating is required above 25 °C ambient per Figure 1 in the datasheet.
Can NHDTC114EUX replace BC846 in existing designs without layout changes?
Yes-NHDTC114EUX uses the same SOT323 (SC-70) footprint as BC846 variants. Pin 1 (input/base), Pin 2 (GND/emitter), and Pin 3 (output/collector) match electrically and mechanically, allowing drop-in substitution if the original design used 10 kΩ base resistors.
Is NHDTC114EUX qualified for automotive applications?
No-per Revision 2 (October 2025) of the datasheet, NHDTC114EUX is no longer AEC-Q101 qualified. The automotive-grade alternative is the NHDTC114EU-Q variant; consult Nexperia's official product selector for Q-grade equivalents.
What is the typical input leakage current at 25 °C?
At VEB = 7 V and Tj = 25 °C, the emitter-base cut-off current (IEBO) is 600 µA max. This value increases with temperature but remains within specification up to 150 °C junction temperature.
