Product details
Overview
NHDTC114YTR from Nexperia is an AEC-Q101-qualified NPN resistor-equipped transistor (RET) in SOT23 package, designed for digital switching applications with 80 V VCEO, 100 mA IO, and integrated 10 kΩ/47 kΩ bias resistors. It replaces discrete BJT + resistor combinations in load switching, IC input control, and automotive body electronics where space and assembly cost reduction are critical.
For engineers reviewing the NHDTC114YTR datasheet, NHDTC114YTR pinout, NHDTC114YTR application, or NHDTC114YTR equivalent, this page delivers verified electrical parameters, validated pin functions, real-world use cases in automotive and industrial digital control, and direct alternatives with documented R1/R2 and VI(on)/VI(off) differences.
Technical Context
This RET integrates a silicon NPN transistor with two monolithic thin-film resistors: R1 = 10 kΩ (base input resistor) and R2 = 47 kΩ (base-emitter feedback resistor), 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) = 1.6 V (typ) at IC = 10 mA and VI(off) = 690 mV (typ) at IC = 100 µA, delivering sharp digital switching thresholds. Thermal resistance Rth(j-a) is 500 K/W on single-sided FR4 PCB, supporting continuous 100 mA operation within ambient limits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Withstands 24 V/48 V system transients without breakdown in digital switch positions. |
| IO | 100 mA - Drives LED indicators, small relays, or logic inputs without external current amplification. |
| R1 / R2 | 10 kΩ / 47 kΩ - Sets precise base bias for predictable turn-on at 1.6 V and robust noise immunity above 690 mV. |
| VCE(sat) | 100 mV (max) at IC = 10 mA, IB = 0.5 mA - Minimizes power loss and self-heating in high-duty-cycle switching. |
| AEC-Q101 | Qualified - Validated for automotive under-hood and body control modules per stress test standard. |
| Ptot | 250 mW (FR4, single-layer) - Enables compact layout without forced cooling in space-constrained PCBs. |
Pinout & Package
Package: SOT23 (TO-236AB), 3-lead surface-mount plastic package, 1.9 mm × 1.1 mm × 1.0 mm profile, optimized for automated pick-and-place and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Logic signal entry point; internally connected to R1 top node-accepts TTL/CMOS voltage levels directly. |
| 2 | GND (emitter) | Emitter tied to ground reference; serves as common return path for both transistor and internal resistors. |
| 3 | Output (collector) | Switched output node; connects to load (e.g., LED anode or relay coil); open-collector compatible. |
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 |
|---|---|---|---|
| NHDTC143ZTR | R1 = 4.7 kΩ, VI(on) = 1.4 V (typ), VI(off) = 625 mV (typ)-lower input threshold, higher base current draw. | Better suited for 1.8 V logic systems; less noise margin than NHDTC114YTR in 3.3 V environments. | Select when driving from low-voltage MCUs or requiring faster turn-on at reduced VIN. |
| BC847B,115 | No integrated resistors; requires external 10 kΩ base resistor and 47 kΩ emitter feedback-+2 components, +1.2 mm² PCB area. | Offers higher hFE (200–450) and lower VCE(sat) (60 mV) but increases design complexity and test points. | Choose only if maximum gain or minimal saturation loss is mandatory and board space is unconstrained. |
Compared with NHDTC143ZTR, NHDTC114YTR provides higher noise immunity and lower base current consumption; versus BC847B, it eliminates two passives and qualifies for automotive use out-of-box-making it optimal for cost-sensitive, space-constrained digital switching.

FAQ
What is the maximum allowable input voltage (VI) for NHDTC114YTR?
The absolute maximum input voltage VI is +40 V, as specified in Table 6 (Limiting Values). This rating applies with emitter grounded and ensures safe operation during transient surges in 24 V automotive or industrial systems. Exceeding +40 V risks irreversible damage to the internal R1 resistor or base-emitter junction.
Does NHDTC114YTR require an external pull-down resistor on the input pin?
No. The internal R2 = 47 kΩ resistor provides a defined base-emitter path, ensuring reliable turn-off without external components. VI(off) = 690 mV (typ) at IC = 100 µA confirms sufficient noise margin to prevent false triggering in noisy environments such as engine bays or factory floors.
Can NHDTC114YTR drive a 50 mA solenoid directly?
Yes-its 100 mA rated output current and 100 mV VCE(sat) (max) at 10 mA allow safe continuous operation at 50 mA, provided PCB thermal design maintains Tj ≤ 150 °C. Derating curves in Figure 1 confirm ≥65 mA capability at +85 °C ambient on standard FR4.
How does the marking code 'QH%' correspond to NHDTC114YTR?
'QH%' is the official top-side marking per Table 5, where 'QH' identifies the NHDTC114YT variant and '%' is a placeholder for the manufacturing site code (e.g., QH1 for Nijmegen, Netherlands). This matches Nexperia's SOT23 marking convention and is laser-etched for traceability in automotive production.
