Product details

Overview

NHDTA114EUX from Nexperia is a PNP resistor-equipped transistor (RET) in SOT323 (SC-70) package, designed for digital switching and IC input control. It features 80 V collector-emitter breakdown voltage, −100 mA output current capability, built-in 10 kΩ input and 10 kΩ emitter resistors, and AEC-Q101 qualification for automotive-grade reliability. It serves as a cost-optimized replacement for BC856-series transistors in low-power logic interface circuits.

For engineers reviewing the NHDTA114EUX datasheet, NHDTA114EUX pinout, NHDTA114EUX application, or NHDTA114EUX equivalent, key selection criteria include its integrated bias network, guaranteed −80 V V_CEO, −100 mV V_CEsat at I_C = −10 mA/I_B = −0.5 mA, thermal resistance of 532 K/W (junction-to-ambient, single-layer PCB), and AEC-Q101 qualification status.

Technical Context

This RET integrates a PNP bipolar transistor with two monolithic silicon resistors: R1 (10 kΩ) between base and input terminal, and R2 (10 kΩ) between base and emitter. The internal topology eliminates external bias components while maintaining predictable turn-on/off thresholds across temperature.

It operates with a typical DC current gain (h_FE) of 50 at V_CE = −5 V and I_C = −10 mA, supports −1.15 V to −0.8 V off-state input voltage (V_I(off)), and delivers −2.5 V to −1.8 V on-state input voltage (V_I(on)) under specified conditions - enabling robust noise margin in 3.3 V/5 V digital systems.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−80 V: Maximum safe collector-emitter voltage before breakdown; enables use in 24 V industrial bus interfaces.
I_O	−100 mA: Continuous output current rating; sufficient for driving LEDs, small relays, or logic inputs.
R1 / R2	10 kΩ / 10 kΩ: Integrated base bias network simplifies PCB layout and reduces BOM count by eliminating two external resistors.
V_CEsat	−100 mV max at I_C = −10 mA/I_B = −0.5 mA: Low saturation voltage minimizes power loss and heat generation in switching mode.
h_FE	50 min at V_CE = −5 V, I_C = −10 mA: Predictable current amplification ensures reliable gate drive or signal inversion without external gain staging.
AEC-Q101	Qualified: Meets stress-test requirements for automotive discrete semiconductors; suitable for under-hood and ADAS subsystems.

Pinout & Package

SOT323 (SC-70) plastic surface-mounted package: 1.3 mm × 1.8 mm footprint, 0.95 mm height, 3-terminal configuration with gull-wing leads. Optimized for reflow soldering per IPC-7095 guidelines.

Pin/Terminal	Circuit Role	Design Meaning
1	Input (base)	Connects to driving logic node; internal R1 pulls base toward this terminal for controlled turn-on.
2	GND (emitter)	Emitter tied to system ground; internal R2 connects base to this terminal for stable bias reference.
3	Output (collector)	Switched high-side load connection point; sinks current when device is active; rated for −80 V reverse blocking.

Key Features

Feature	Design Value
Integrated R1/R2 network	Eliminates need for two external bias resistors, reducing PCB area and assembly steps in digital interface designs.
−100 mA output capability	Supports direct driving of moderate-current loads such as optocoupler LEDs or microcontroller GPIO protection networks.
−80 V V_CEO rating	Provides headroom for transient suppression in 24 V industrial control lines and automotive battery-supplied modules.
AEC-Q101 qualification	Validated for automotive applications including body electronics, lighting control, and sensor interface modules.

Applications

Automotive Lighting Control

Industrial PLC Input Conditioning

Use Scenario: Switching 12 V LED strings in interior lighting modules using MCU GPIO signals.

IC Role / Device Role / Timing Role: High-side switch controlling current path to LED anodes; replaces discrete BJT + resistor pair.

Use Value: Built-in 10 kΩ resistors ensure consistent turn-on threshold across temperature, reducing calibration overhead in production test.

Use Scenario: Converting 24 V field signals to 3.3 V logic levels for PLC digital input cards.

IC Role / Device Role / Timing Role: Level-shifting interface device with inherent current limiting and ESD robustness.

Use Value: −80 V V_CEO withstands common-mode surges on industrial I/O lines; AEC-Q101 grade adds long-term reliability assurance.

Consumer Appliance Power Sequencing

IoT Sensor Node Wake-Up Circuit

Use Scenario: Enabling auxiliary power rails only after main MCU asserts a valid enable signal.

IC Role / Device Role / Timing Role: Digital enable switch isolating downstream LDOs or DC-DC converters.

Use Value: −100 mV V_CEsat minimizes dropout voltage and self-heating during continuous conduction in always-on subsystems.

Use Scenario: Waking ultra-low-power microcontrollers from deep sleep using external interrupt sources.

IC Role / Device Role / Timing Role: Edge-triggered wake-up signal conditioner with defined hysteresis via internal resistor ratio.

Use Value: Matched R1/R2 values (10 kΩ/10 kΩ) provide symmetric VI(on)/VI(off) thresholds, improving noise immunity in battery-powered edge nodes.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP resistor-equipped transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
NHDTC114EU	NPN complement with identical R1/R2 values (10 kΩ/10 kΩ), same SOT323 package, but opposite polarity.	Used where low-side switching or inverted logic control is required instead of high-side sourcing.	Select when circuit topology demands NPN configuration - e.g., sinking current from a pull-up rail rather than sourcing to ground.
BC856B,215	Discrete PNP BJT without integrated resistors; requires external base bias network; lower V_CEO (−65 V).	Offers higher h_FE (160–250) but increases component count and layout complexity.	Choose only if precise gain tuning or higher current gain is critical and board space allows for two extra resistors.

Compared with NHDTC114EU, NHDTA114EUX provides complementary high-side switching functionality in identical form factor; versus BC856B,215, it trades raw gain for reduced bill-of-materials and improved manufacturing yield through integration.

FAQ

What is the maximum junction temperature for NHDTA114EUX?

The absolute maximum junction temperature (T_j) is 150 °C, as defined in the Absolute Maximum Ratings table. Operation above this limit risks permanent degradation of the silicon die and integrated resistors. Derating is required above ambient temperatures of 25 °C per the power derating curve in Figure 1.

Can NHDTA114EUX replace BC856B in existing designs without layout changes?

No - NHDTA114EUX has different pinout (input/base on pin 1, GND/emitter on pin 2, output/collector on pin 3) versus BC856B's standard TO-92/SOT23 pinout. Additionally, its integrated resistors alter bias behavior; redesign of drive strength and logic thresholds is required for functional equivalence.

Is NHDTA114EUX suitable for linear amplifier applications?

No - it is optimized for saturated switching operation, not analog amplification. Its h_FE variation over current and temperature, lack of guaranteed linearity specs, and integrated resistors make it unsuitable for Class-A or AB amplifier stages where gain stability and low distortion are critical.

Does NHDTA114EUX support wave soldering?

Yes - the SOT323 package is qualified for both reflow and wave soldering. Figure 26 provides the recommended wave soldering footprint with 3× solder lands (0.55 mm pitch), and the device meets JEDEC J-STD-020 moisture sensitivity level 1, allowing unlimited floor life before assembly.
