Product details
Overview
NHDTC114YUF 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 10 kΩ/47 kΩ bias resistors. It replaces discrete BJT + resistor networks in load control and IC input interfacing for automotive and industrial embedded systems.
For engineers reviewing the NHDTC114YUF datasheet, NHDTC114YUF pinout, NHDTC114YUF application, or NHDTC114YUF equivalent, this page delivers verified electrical specs, thermal derating behavior, validated pin functions, and direct alternatives for cost-sensitive digital switching designs requiring AEC-Q101 compliance and space-constrained SMD layouts.
Technical Context
This RET integrates a monolithic NPN transistor with two precision laser-trimmed on-die resistors: R1 = 10 kΩ (input bias) and R2 = 47 kΩ (base-emitter feedback), enabling single-pin logic-level drive without external components. Its 80 V breakdown rating supports 24 V and 48 V industrial bus interfaces.
The device operates with VI(on) = 1.22 V (typ) at IC = 10 mA and VCE = 0.3 V, and VI(off) = 0.69 V (typ) at IC = 100 µA, ensuring robust noise immunity in noisy environments. Thermal resistance Rth(j-a) is 532 K/W on single-sided FR4, limiting continuous power to 235 mW at 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Supports 24 V/48 V supply rails with 2× safety margin against transients |
| IO | 100 mA - Drives LED arrays, small relays, or logic inputs without external current amplification |
| R1 / R2 | 10 kΩ / 47 kΩ - Enables direct 3.3 V/5 V microcontroller GPIO drive with no external resistors |
| VCE(sat) | 100 mV (max) at IC = 10 mA, IB = 0.5 mA - Minimizes conduction loss in high-duty-cycle switching |
| AEC-Q101 | Qualified - Validated for automotive body electronics, HVAC controls, and under-hood modules |
| Ptot | 235 mW (FR4, single-layer) - Sets practical current limit to ~80 mA at 60 °C ambient |
| fT | 170 MHz - Ensures fast turn-on/turn-off for PWM frequencies up to 100 kHz with low delay |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package: 1.3 mm × 1.8 mm × 0.95 mm profile, 3-terminal leadframe, optimized for reflow soldering per IPC-7351B footprint (solder pad pitch: 0.65 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Logic-level node connected internally to R1; accepts 0.69–1.6 V drive for reliable switching |
| 2 | GND (emitter) | Reference return path for both transistor and internal resistors; must be low-impedance ground |
| 3 | Output (collector) | Switched high-side output capable of sinking 100 mA into loads tied to positive rail |
Key Features

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; requires external 10 kΩ base resistor and lacks integrated R2 feedback path | Higher board area, additional pick-and-place step, no guaranteed VI(off) noise margin | Select only if legacy design reuse or parametric tuning of R1/R2 values is required |
| NHDTC143ZU | R1 = 4.7 kΩ (lower input impedance); identical R2 = 47 kΩ and 80 V/100 mA ratings | Better suited for 5 V logic drive; higher input current draw reduces noise immunity in 3.3 V systems | Prefer for 5 V MCU interfaces where VI(on) margin >1.4 V is available and lower input impedance is acceptable |
Compared with BC846B,115, NHDTC114YUF reduces component count and improves noise immunity via integrated R2; compared with NHDTC143ZU, it offers superior 3.3 V compatibility with higher VI(on) threshold and lower input current, making it optimal for modern low-voltage embedded controllers.

FAQ
What is the maximum allowable input voltage (VI) for NHDTC114YUF?
The absolute maximum input voltage VI is +40 V, as specified in Table 6 (Limiting Values). Operation above this level risks permanent damage to the internal R1 resistor and transistor junction. For reliable 3.3 V or 5 V logic interfacing, VI remains within 0.69–1.6 V (VI(off) to VI(on)), ensuring safe and predictable switching behavior without external clamping.
Can NHDTC114YUF replace BC846 series transistors directly?
Yes - as a functional drop-in replacement in digital switching applications, provided the circuit uses the same SOT323 footprint and does not rely on adjustable base bias. NHDTC114YUF integrates R1/R2, eliminating two external resistors while maintaining compatible VCEO, IO, and pinout. However, its fixed bias network means it cannot replicate variable-gain or analog amplifier configurations used with BC846.
How does thermal performance differ between single-layer and 4-layer PCB mounting?
On single-sided FR4, Rth(j-a) = 532 K/W limits usable power to 235 mW at 25 °C ambient; on 4-layer copper PCBs, Rth(j-a) drops to 397 K/W, raising Ptot to 315 mW. This 34% thermal improvement allows sustained 100 mA operation up to 75 °C ambient versus 60 °C on basic boards - critical for enclosed automotive modules.
Is NHDTC114YUF suitable for linear (analog) amplifier use?
No - it is optimized for saturated switching, not linear operation. Its hFE is specified only at IC = 10 mA (min 100), with no guaranteed gain linearity or frequency response beyond fT = 170 MHz. The integrated resistors fix bias conditions, preventing external adjustment needed for stable analog amplification. Use discrete BJTs like BC846 for amplifier stages.
