Product details
Overview
NHDTA143ZUF from Nexperia is a PNP resistor-equipped transistor (RET) in SOT323 (SC-70) package, designed for digital switching and IC input control with −80 V collector-emitter breakdown voltage, −100 mA output current capability, built-in 4.7 kΩ input bias resistor (R1) and 47 kΩ feedback resistor (R2), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the NHDTA143ZUF datasheet, NHDTA143ZUF pinout, NHDTA143ZUF application, or NHDTA143ZUF equivalent, this device serves as a space-optimized, component-count-reducing alternative to discrete BJT + resistor networks in low-power digital interface and load-switching circuits.
Technical Context
This PNP RET integrates a silicon transistor with two precision on-die resistors-R1 (4.7 kΩ) connected between base and input terminal, and R2 (47 kΩ) between base and emitter-to enable single-pin logic-level drive without external bias components. It operates with open-base VCEO = −80 V and supports continuous IO up to −100 mA at Tamb ≤ 25 °C.
The device exhibits VI(on) = −0.95 V (typ) at IC = −10 mA and VCE = −0.3 V, and VI(off) = −625 mV (min) at VCE = −5 V, enabling robust noise margin in 3.3 V/5 V digital systems. Its fT = 150 MHz (typ) confirms suitability for high-speed switching up to several tens of MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −80 V: Maximum safe collector-emitter voltage before breakdown; enables use in 24 V automotive and industrial supply rails. |
| IO | −100 mA: Continuous DC output current rating; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 | 4.7 kΩ: Integrated base-input resistor; eliminates need for external pull-up/pull-down in standard TTL/CMOS interface. |
| R2/R1 | 10: Fixed internal resistor ratio; sets stable current gain and ensures predictable turn-on/off thresholds. |
| VI(on) | −0.95 V (typ): Input voltage required to achieve IC = −10 mA at VCE = −0.3 V; compatible with 3.3 V logic high. |
| VI(off) | −625 mV (min): Maximum input voltage that guarantees IC ≤ −100 µA; provides ≥1.5 V noise immunity vs. 3.3 V logic low. |
| Ptot | 315 mW (4-layer PCB): Maximum power dissipation under optimized thermal layout; supports sustained operation at full rated current. |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package: 1.35 mm × 1.15 mm × 0.45 mm body, 3-terminal leadframe, moisture sensitivity level (MSL) 1, reflow-compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Logic signal entry point; internally connected to R1; accepts direct microcontroller GPIO or logic gate output. |
| 2 | GND (emitter) | Emitter tied to system ground; serves as common reference and current return path for switched loads. |
| 3 | Output (collector) | High-side switch output; sinks current from VCC-referenced loads (e.g., LED anode, relay coil top side). |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications per stress test requirements; supports under-hood and infotainment module deployment. |
| Integrated R1 + R2 network | Eliminates two external resistors; reduces PCB area by ~1.5 mm² and assembly cost per unit in high-volume production. |
| −80 V VCEO rating | Withstands transients up to ISO 7637-2 Pulse 1 (−100 V/50 ms); suitable for 24 V commercial vehicle and industrial control systems. |
| VI(off) ≤ −625 mV | Ensures reliable cutoff with 3.3 V CMOS outputs; prevents unintended conduction when driving from low-voltage MCUs. |
| SOT323 footprint | Compatible with standard SC-70 reflow profiles and automated pick-and-place; supports >10,000 units/hour placement throughput. |
Applications
| LED Indicator Control | Microcontroller GPIO Expansion |
|---|---|
|
Use Scenario: Driving status LEDs from 3.3 V MCU GPIO pins with limited sink current capability. IC Role / Device Role / Timing Role: High-side PNP switch that inverts logic and sources current to LED anodes while sinking through emitter to GND. Use Value: Eliminates need for external base resistor and pull-down; reduces bill-of-materials by two passives per LED channel. |
Use Scenario: Expanding digital output count using low-cost discrete logic-level translators. IC Role / Device Role / Timing Role: Level-shifting buffer that converts 3.3 V logic signals to 5 V/12 V compatible outputs with <100 ns propagation delay. Use Value: Enables direct connection to legacy 5 V peripherals without dedicated level-shifter ICs or voltage dividers. |
| Automotive Door Module Inputs | Industrial Sensor Interface Conditioning |
|
Use Scenario: Debounced switch sensing in automotive door control units exposed to load dump transients. IC Role / Device Role / Timing Role: ESD-hardened input stage that clamps and conditions mechanical switch signals before MCU sampling. Use Value: Withstands −80 V transients and meets AEC-Q101; replaces discrete TVS + BJT + resistor solution in space-constrained modules. |
Use Scenario: Isolating and conditioning open-collector sensor outputs (e.g., Hall effect, proximity) in PLC I/O cards. IC Role / Device Role / Timing Role: Digital interface translator that converts sensor's active-low signal into clean, rail-to-rail logic levels for FPGA/CPLD inputs. Use Value: Provides built-in hysteresis via R1–R2 feedback; improves noise immunity in electrically noisy factory environments. |
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 |
|---|---|---|---|
| NHDTC143ZU | NPN complement with identical R1/R2 values; requires inverted logic drive and low-side switching topology. | Used where load connects to VCC and switch sinks to GND; incompatible with high-side sourcing configurations. | Select when existing PCB layout uses NPN-based routing or when interfacing with open-collector drivers. |
| BC856B,115 | Discrete PNP BJT without integrated resistors; requires external 4.7 kΩ and 47 kΩ bias network. | Offers higher hFE (200–450) but increases component count, layout area, and assembly cost. | Choose only if precise gain tuning or thermal derating beyond RET limits is required. |
Compared with NHDTC143ZU, NHDTA143ZUF enables high-side sourcing without logic inversion; compared with BC856B, it reduces passive count by two per channel and improves production yield via monolithic integration.

FAQ
What is the maximum operating temperature for NHDTA143ZUF?
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 ~180 mW on a 4-layer FR4 board.
Can NHDTA143ZUF replace BC856 in existing designs?
Yes, as a drop-in replacement in most digital switching roles-but with key differences: NHDTA143ZUF has fixed internal resistors (R1 = 4.7 kΩ, R2 = 47 kΩ), so no external biasing is needed, and its VI(on) and VI(off) are defined by those values rather than external component selection.
Is NHDTA143ZUF suitable for PWM-driven loads?
Yes-its fT = 150 MHz (typ) and fast VCE(sat) response (<100 ns rise/fall in typical conditions) support PWM frequencies up to 10 MHz. However, thermal limits must be observed: at 50% duty cycle and 100 mA peak, average power must stay below derated Ptot.
Does NHDTA143ZUF have ESD protection?
The device is not specified with on-chip ESD diodes, but its AEC-Q101 qualification includes human-body model (HBM) testing per JESD22-A114 (≥2 kV). For harsh environments, external TVS (e.g., PESD5V0S1BA) on the input pin is recommended.
