Product details
Overview
NHDTA124EUX 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 22 kΩ base resistors (R1 = R2), −80 V collector-emitter breakdown voltage, −100 mA output current capability, and AEC-Q101 qualification for automotive use.
For engineers reviewing the NHDTA124EUX datasheet, NHDTA124EUX pinout, NHDTA124EUX application, or NHDTA124EUX equivalent, this device serves as a space- and BOM-optimized replacement for discrete PNP + bias resistor networks in low-power digital logic interfaces, microcontroller I/O conditioning, and load switching circuits.
Technical Context
This RET integrates a PNP bipolar transistor with two precision-matched on-die base resistors (R1 = R2 = 22 kΩ), enabling single-pin input drive without external bias components. Its open-base VCEO rating of −80 V supports robust operation in 24 V industrial and 12 V automotive supply domains.
The device delivers hFE = 70 at VCE = −5 V and IC = −10 mA, with VCE(sat) ≤ −100 mV under IC = −10 mA / IB = −0.5 mA conditions, ensuring low-loss switching in signal-level and small-signal load control applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −80 V - Withstands up to 80 V reverse collector-emitter voltage before breakdown, suitable for 24 V rail switching. |
| IO | −100 mA - Continuous DC output current capacity enables driving LEDs, small relays, or logic inputs. |
| R1 / R2 | 22 kΩ each - Integrated base bias resistors eliminate need for external components and reduce PCB footprint. |
| VCE(sat) | ≤ −100 mV @ IC = −10 mA - Low saturation voltage minimizes power loss and heat generation during on-state operation. |
| hFE | 70 @ VCE = −5 V, IC = −10 mA - Predictable current gain simplifies drive circuit design without iterative biasing. |
| AEC-Q101 | Qualified - Meets stress-test requirements for automotive-grade reliability in under-hood and infotainment systems. |
| Ptot | 315 mW @ 4-layer FR4 PCB - Enables stable thermal performance in compact, high-density layouts. |
Pinout & Package
SOT323 (SC-70) plastic surface-mounted package: ultra-compact 3-lead outline measuring 2.2 mm × 1.35 mm × 0.95 mm (L × W × H), optimized for high-density PCB assembly and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Driven node connecting to controller output; internal R1 routes to base, R2 ties base to emitter. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common reference and current return path. |
| 3 | Output (collector) | Switched high-side output node; sinks current from load connected to positive supply rail. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1/R2 bias network | Eliminates 2 external resistors, reducing BOM count and placement cost in digital interface designs. |
| −100 mA output current | Supports direct driving of optocouplers, small solenoids, and LED indicators without buffer stages. |
| −80 V VCEO rating | Provides margin against transients in 24 V industrial control and automotive body electronics. |
| AEC-Q101 qualification | Validated for automotive temperature range (−40 °C to +150 °C) and mechanical stress requirements. |
| SOT323 footprint compatibility | Enables drop-in replacement for BC856-family transistors while reducing board area by >40%. |
Applications
| Automotive Body Control | Industrial PLC I/O |
|---|---|
|
Use Scenario: Controlling door lock actuators and interior lighting via MCU GPIO pins in vehicle body control modules. IC Role / Device Role / Timing Role: High-side switch that sinks current from 12 V loads using MCU's 3.3 V/5 V logic 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 |
|---|---|---|---|
| NHDTC124EU | NPN complement with identical R1/R2 = 22 kΩ, same SOT323 package, but opposite polarity. | Used where active-high switching or sourcing (vs sinking) is required; not interchangeable without circuit redesign. | Select when load must be connected to ground side and driven from positive rail. |
| BC856B,215 | Discrete PNP transistor only-no integrated resistors; requires external 22 kΩ base bias network. | Higher BOM count and layout complexity; lacks AEC-Q101 qualification and guaranteed resistor matching. | Choose only if legacy design reuse or parametric tuning of R1/R2 values is needed. |
Compared with NHDTC124EU, NHDTA124EUX provides complementary high-side switching functionality with matched internal resistors and automotive qualification; versus BC856B,215, it reduces component count by two resistors and guarantees resistor tolerance and thermal tracking across temperature.

FAQ
What is the maximum continuous collector current for NHDTA124EUX?
The NHDTA124EUX supports a maximum continuous output current of −100 mA at Tamb ≤ 25 °C with appropriate PCB copper layer configuration. Derating applies above 25 °C ambient per Figure 1 in the datasheet, reaching zero allowable current at ~150 °C junction temperature.
Can NHDTA124EUX replace BC856B in existing designs without modification?
No-NHDTA124EUX integrates 22 kΩ base resistors, whereas BC856B is a bare transistor requiring external biasing. Direct substitution would alter base drive characteristics and likely cause incorrect switching behavior unless the external resistors are removed and layout verified for thermal and signal integrity.
Is the SOT323 package of NHDTA124EUX compatible with standard reflow profiles?
Yes-the SOT323 (SC-70) package is qualified for lead-free reflow soldering per JEDEC J-STD-020. Recommended profile uses peak temperature of 260 °C for ≤ 30 seconds, with preheat ramp rate ≤ 3 °C/s and cooling rate ≥ 1 °C/s, matching industry-standard Class 3 assembly processes.
Does NHDTA124EUX support bidirectional signal translation?
No-it is a unidirectional PNP switch optimized for high-side current sinking. It does not support reverse conduction or analog signal buffering. For bidirectional level shifting, dedicated translators like NXH010P0206 or discrete resistor-divider + buffer solutions are required.
