Product details
Overview
NHDTA114EUF from Nexperia is a PNP resistor-equipped transistor (RET) in SOT323 (SC-70) package, designed for digital switching and IC input control. It features built-in 10 kΩ base resistors (R1 = R2 = 10 kΩ), −80 V collector-emitter breakdown voltage (VCEO), −100 mA output current capability, and AEC-Q101 qualification for automotive use.
For engineers reviewing the NHDTA114EUF datasheet, NHDTA114EUF pinout, NHDTA114EUF application, or NHDTA114EUF equivalent, key selection criteria include its integrated bias network, low saturation voltage (−100 mV at IC = −10 mA / IB = −0.5 mA), thermal resistance (532 K/W on single-sided FR4), and compatibility with cost-sensitive digital logic interface designs.
Technical Context
This RET integrates a PNP bipolar transistor with two monolithic silicon resistors (R1 and R2) forming a fixed-current bias network. Its internal topology eliminates external base resistors, enabling direct connection to CMOS/TTL outputs without level-shifting components.
The device operates with an off-state input voltage (VI(off)) of −1.15 V to −0.8 V and on-state input voltage (VI(on)) of −2.5 V to −1.8 V at VCE = −0.3 V and IC = −10 mA, ensuring reliable turn-on/turn-off across industrial temperature range (−55 °C to +150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −80 V - Withstands high-voltage loads in automotive and industrial switching without external protection. |
| IO | −100 mA - Drives moderate-current loads such as LEDs, relays, or logic inputs directly. |
| R1 / R2 | 10 kΩ / 10 kΩ - Provides fixed base bias for predictable switching thresholds and eliminates discrete resistor placement. |
| VCE(sat) | −100 mV @ IC = −10 mA, IB = −0.5 mA - Minimizes conduction loss and self-heating in high-duty-cycle applications. |
| Ptot | 235 mW @ Tamb ≤ 25 °C (single-sided FR4) - Defines maximum continuous power handling under standard PCB layout conditions. |
| hFE | 50 @ VCE = −5 V, IC = −10 mA - Ensures sufficient current gain for stable saturation with integrated bias network. |
| fT | 150 MHz @ VCE = −5 V, IC = −10 mA - Supports fast digital switching up to ~10–20 MHz edge rates without oscillation risk. |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package: 3-pin, ultra-small footprint (2.2 mm × 1.35 mm × 0.95 mm), optimized for high-density PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Internal connection to R1–R2 node; accepts logic-level drive signals directly from microcontrollers or gate outputs. |
| 2 | GND (emitter) | Emitter tied to system ground; serves as common reference for load return path and resistor network. |
| 3 | Output (collector) | Switched high-side output node; connects to load (e.g., LED anode, relay coil) referenced to positive rail. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness per JESD22 standards. |
| Integrated R1/R2 bias network | Eliminates two external resistors, reducing BOM count, PCB area, and pick-and-place steps in production. |
| Low VCE(sat) | −100 mV enables <10 mW conduction loss at 100 mA, improving efficiency and thermal margin in compact enclosures. |
| High VCEO rating | −80 V supports operation in 24 V and 48 V industrial systems with safety margin against transients and inductive kickback. |
| SC-70 footprint compatibility | Standardized land pattern (JEITA SC-70 / SOT323) ensures drop-in replacement and compatibility with existing reflow profiles. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Output |

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 |
|---|---|---|---|
| BC856B,115 | Discrete PNP BJT (no built-in resistors); requires external base bias network; hFE = 220–475; VCEO = −65 V. | Higher gain but lower breakdown voltage; needs two extra 10 kΩ resistors and additional layout space. | Select when higher hFE or tighter VBE tolerance is required, and board space allows discrete biasing. |
| NHDTC114EU | NPN complement with identical R1/R2 values (10 kΩ), same SOT323 package, −80 V VCEO, −100 mA IO. | Used in low-side switching configurations where emitter connects to ground and collector drives load to VCC. | Choose for complementary NPN implementation in push-pull or dual-rail logic interfaces. |
Compared with BC856B,115, NHDTA114EUF reduces bill-of-materials and layout complexity at the cost of fixed bias ratio; versus NHDTC114EU, it provides high-side switching capability essential for grounded-load topologies in automotive and industrial controls.

FAQ
What is the maximum operating temperature for NHDTA114EUF?
The junction temperature limit is 150 °C, and ambient operating range extends from −55 °C to +150 °C. Derating begins above 25 °C ambient per Figure 1: at 100 °C ambient, maximum allowable power dissipation drops to ~120 mW on single-sided FR4 PCB.
Can NHDTA114EUF replace BC856 in existing designs?
Yes - as a functional upgrade: it matches BC856's −65 V VCEO rating with improved −80 V, adds integrated 10 kΩ bias resistors, and maintains compatible SOT323 footprint. Layout changes are limited to removing two external resistors and verifying logic polarity (PNP high-side vs. BJT low-side).
Is NHDTA114EUF suitable for PWM-driven LED dimming?
Yes - its 150 MHz fT and −100 mV VCE(sat) support clean switching up to 20 kHz PWM frequencies. Thermal resistance (532 K/W) requires attention to copper pour area; typical 100 mA pulsed operation at 50% duty cycle stays within safe junction limits on standard FR4.
Does NHDTA114EUF require external protection against inductive kickback?
No external flyback diode is needed for loads ≤100 mA and VL ≤24 V due to its −80 V VCEO rating, which absorbs typical inductive transients. For 48 V systems or highly inductive relays, a TVS or clamp diode remains recommended per IEC 61000-4-5 surge immunity requirements.
