Product details
Overview
NHDTA123JTR from Nexperia is a PNP resistor-equipped transistor (RET) in SOT23 (TO-236AB) package, designed for digital switching and IC input control. It delivers −100 mA output current, supports −80 V collector-emitter breakdown voltage, and integrates 2.2 kΩ input bias resistor (R1) and 47 kΩ feedback resistor (R2), enabling direct logic-level drive in automotive and industrial interface circuits.
For engineers reviewing the NHDTA123JTR datasheet, NHDTA123JTR pinout, NHDTA123JTR application, or NHDTA123JTR equivalent, this device serves as a drop-in replacement for BC856-series transistors in load-switching and signal-level translation where built-in biasing reduces BOM count and improves layout efficiency.
Technical Context
This PNP RET integrates two on-die resistors to form a self-biased switching structure: R1 connects base to input, R2 connects base to emitter, establishing fixed bias ratio (R2/R1 ≈ 21) that ensures stable turn-on/off thresholds across temperature. Its −80 V VCEO rating enables use in 24 V and 48 V industrial bus interfaces.
The device operates with −100 mV typical VCE(sat) at IC = −10 mA / IB = −0.5 mA and exhibits −0.81 V typical VI(on) at VCE = −0.3 V, supporting reliable low-voltage logic compatibility while maintaining AEC-Q101 qualification for automotive under-hood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −80 V: Enables safe operation in 48 V systems with margin against transients. |
| IO | −100 mA: Sufficient to drive LED indicators, small relays, or logic inputs directly. |
| R1 | 2.2 kΩ: Sets input current sensitivity for TTL/CMOS-compatible switching thresholds. |
| R2/R1 | 21: Provides predictable current gain stabilization and reduces dependency on hFE variation. |
| VCE(sat) | −100 mV max at IC = −10 mA: Minimizes conduction loss in always-on or pulsed load control. |
| AEC-Q101 | Qualified: Validated for automotive temperature range (−40 °C to +150 °C) and reliability stress tests. |
| Ptot | 250 mW (FR4 single-layer): Supports continuous operation in compact PCB layouts without forced cooling. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package with 3 leads; 1.3 mm × 2.9 mm footprint, 1.1 mm height, and gull-wing lead form compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Accepts logic-level control signal; internally connected to R1 and R2 network. |
| 2 | GND (emitter) | Common reference node; tied to system ground or negative rail for PNP sourcing configuration. |
| 3 | Output (collector) | Switches high-side loads; sinks current when active, requiring external pull-up to positive supply. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistors | Eliminates need for two external resistors, reducing PCB area by ~2.5 mm² and assembly steps. |
| −100 mA output capability | Drives medium-current loads such as optocoupler LEDs or microcontroller reset lines without buffer stages. |
| −80 V breakdown rating | Supports robust operation in 24/48 V industrial control and automotive body electronics. |
| AEC-Q101 qualification | Validated for automotive under-hood environments including thermal cycling, humidity, and mechanical shock. |
Applications
| LED Driver Interface | Microcontroller Input Protection |
|---|---|
Use Scenario: Driving status indicator LEDs from 3.3 V or 5 V MCU GPIO pins in automotive instrument clusters. IC Role / Device Role / Timing Role: PNP switch sourcing current from 12 V rail to LED anode, with cathode grounded via current-limiting resistor. Use Value: Built-in R1/R2 eliminates discrete bias network, reducing component count and improving ESD robustness at the GPIO interface. |
Use Scenario: Level-shifting and protecting 3.3 V microcontroller input pins from 12 V sensor signals in industrial PLC modules. IC Role / Device Role / Timing Role: Acts as active clamp and voltage translator, pulling MCU input low when sensor asserts 12 V. Use Value: −80 V VCEO and integrated resistors prevent overvoltage damage while maintaining fast edge response (<100 ns typical). |
| Relay Coil Driver | Power Supply Enable Control |
Use Scenario: Switching 24 V relay coils in HVAC control panels using low-power logic outputs. IC Role / Device Role / Timing Role: High-side switch connecting relay coil between 24 V supply and collector, emitter grounded. Use Value: −100 mA rating and −100 mV VCE(sat) minimize power dissipation (≤10 mW) during sustained activation. |
Use Scenario: Enabling 5 V LDO outputs in battery-powered medical devices based on system wake-up signals. IC Role / Device Role / Timing Role: Controls enable pin of voltage regulator by pulling it low when active; open-collector compatible. Use Value: Low VI(off) (−500 mV) ensures clean logic-low assertion even with weak pull-ups, preventing false enable states. |
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 |
|---|---|---|---|
| NHDTC123JT | NPN complement with same R1/R2 values; requires inverted logic drive and low-side switching topology. | Used where load must be switched to ground instead of high-side sourcing. | Select when circuit already uses NPN-based layout or requires common-emitter configuration with grounded load. |
| BC856B,215 | Discrete PNP transistor without built-in resistors; requires two external bias resistors and higher layout area. | Offers higher hFE (200–450) but increases BOM count and design validation effort. | Choose only if precise gain tuning or higher current gain is required and board space permits discrete bias network. |
Compared with NHDTC123JT, NHDTA123JTR provides high-side sourcing capability and simplifies level-shifted control; versus BC856B, it trades minor hFE reduction for guaranteed bias stability, reduced test points, and AEC-Q101 compliance out-of-box.

FAQ
What is the maximum allowable continuous collector current for NHDTA123JTR?
The absolute maximum continuous collector current is −100 mA at Tamb ≤ 25 °C on FR4 PCB with single-sided copper. Derating applies above 25 °C per Fig. 1: at 75 °C ambient, maximum sustainable current drops to ~65 mA to maintain junction temperature below 150 °C.
Can NHDTA123JTR be used in 5 V logic systems with 3.3 V microcontrollers?
Yes - its −0.81 V typical VI(on) at IC = −10 mA ensures reliable turn-on with 3.3 V GPIO outputs, and −500 mV VI(off) guarantees solid cutoff with standard pull-up configurations, eliminating need for additional level-shifting circuitry.
How does the built-in resistor network affect switching speed?
The R1/R2 network limits base charging/discharging rate, resulting in typical turn-on/turn-off times of 150 ns/120 ns respectively. This is sufficient for <1 MHz digital switching but not recommended for >5 MHz PWM due to RC time constant constraints.
Is NHDTA123JTR pin-compatible with standard SOT23 PNP transistors like BC856?
No - although both use SOT23 package, NHDTA123JTR has dedicated input (pin 1), GND/emitter (pin 2), and output/collector (pin 3) assignments, whereas BC856 uses emitter-base-collector pinout. Direct replacement requires PCB layout revision to match RET-specific pin mapping.
