Product details
Overview
NHDTA144ETR from Nexperia is a PNP resistor-equipped transistor (RET) in SOT23 (TO-236AB) package, designed for digital switching and IC input control. It features 80 V collector-emitter breakdown voltage, 100 mA output current capability, built-in 47 kΩ input and feedback resistors (R1 = R2 = 47 kΩ), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the NHDTA144ETR datasheet, NHDTA144ETR pinout, NHDTA144ETR application, or NHDTA144ETR equivalent, this device serves as a drop-in replacement for BC856-series transistors in load-switching and logic-level translation circuits where simplified biasing and reduced BOM count are critical.
Technical Context
This PNP RET integrates a silicon bipolar transistor with two monolithic thin-film resistors-R1 connected between base and input, R2 between base and emitter-enabling single-resistor external drive and eliminating discrete bias networks. Its -80 V VCEO and -100 mA IO rating support robust operation in 24 V industrial and 12 V automotive supply rails.
The device exhibits hFE = 100 (at VCE = -5 V, IC = -10 mA), VCE(sat) ≤ -100 mV (IC = -10 mA, IB = -0.5 mA), and VI(on) = -5 V to -3.3 V range, ensuring reliable turn-on across temperature (-40 °C to +150 °C junction).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -80 V - Withstands up to 80 V reverse collector-emitter voltage before breakdown, enabling use in 24 V systems with margin. |
| IO | -100 mA - Continuous DC output current capacity supports driving medium-power loads like LEDs, relays, or logic inputs. |
| R1 / R2 | 47 kΩ / 47 kΩ - Matched internal bias resistors simplify PCB layout and eliminate need for external base resistors in standard switch configurations. |
| hFE | 100 (min) - Ensures sufficient current gain at IC = -10 mA, reducing required drive current and easing microcontroller GPIO loading. |
| VCE(sat) | ≤ -100 mV - Low saturation voltage minimizes power loss and heat generation during on-state operation. |
| VI(on) | -5 V to -3.3 V - Defined input voltage range for guaranteed turn-on, compatible with TTL and CMOS logic thresholds. |
| AEC-Q101 | Qualified - Meets stress-test requirements for automotive discrete semiconductors, supporting under-hood and body-control applications. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package with 3 leads, 1.3 mm max height, and standard reflow footprint per JEDEC MO-203AA.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base node) | Connected internally to R1; accepts logic-level control signal to activate transistor. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; provides return path for load current. |
| 3 | Output (collector) | Switched high-side output node; connects to load anode or pull-up rail in PNP configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1/R2 bias network | Eliminates 2 external resistors, reducing PCB area and assembly cost by ~0.5 mm² and one pick-and-place step. |
| 100 mA output current | Supports direct driving of small solenoids, optocouplers, or multiple logic inputs without external buffer stages. |
| -80 V VCEO | Provides 3× margin over 24 V nominal systems, improving surge immunity and long-term reliability in industrial environments. |
| AEC-Q101 qualification | Validated for automotive temperature cycling, humidity, and mechanical shock, enabling use in body electronics and lighting modules. |
| VCE(sat) ≤ -100 mV | Reduces conduction loss to < 1 mW at 10 mA, minimizing self-heating and enabling higher-density board layouts. |
Applications
| Automotive Lighting Control | Industrial PLC Input Conditioning |
|---|---|
Use Scenario: Switching 12 V LED headlamp modules in body control units. IC Role / Device Role / Timing Role: PNP high-side switch controlling current flow from battery rail to LED anode. Use Value: Built-in 47 kΩ resistors enable direct MCU GPIO drive without external biasing, reducing component count and failure points. |

IC Role / Device Role / Timing Role: Load switch managing power delivery to subsystems based on MCU command. Use Value: 100 mA rating and low VCE(sat) allow efficient gating of moderate-current peripherals while maintaining thermal safety. |
Use Scenario: Isolating sensor supply domains during sleep mode in battery-powered environmental monitors. IC Role / Device Role / Timing Role: Low-leakage PNP switch disconnecting sensors to minimize quiescent current. Use Value: ICEO ≤ -5 µA at 150 °C ensures sub-1 µA total shutdown current, extending battery life beyond 5 years in deep-sleep cycles. |
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 without integrated resistors; requires external RB and RBE for biasing. | Higher design flexibility but increases BOM count and layout complexity; not AEC-Q101 qualified. | Select when custom bias ratios or higher hFE (>200) are needed, and automotive qualification is not required. |
| NHDTC144ETR | NPN complement with identical R1/R2 = 47 kΩ, same SOT23 package, and matching -80 V/-100 mA ratings. | Used in low-side switching configurations where emitter is grounded and collector drives load to VCC. | Select for complementary NPN topology in H-bridge drivers or dual-rail logic interfaces requiring matched RET characteristics. |
Compared with BC856B,115, NHDTA144ETR reduces bill-of-materials and layout effort via integrated biasing; compared with NHDTC144ETR, it enables high-side switching in PNP topology while maintaining identical resistor values and voltage/current ratings.

FAQ
What is the maximum operating temperature for NHDTA144ETR?
The NHDTA144ETR has a maximum junction temperature (Tj) of 150 °C and operates across an ambient temperature range of -55 °C to +150 °C. Its thermal resistance Rth(j-a) is 500 K/W on single-layer FR4 PCB, requiring derating above 25 °C ambient per Figure 1 in the datasheet.
Can NHDTA144ETR replace BC856B in existing designs?
Yes, NHDTA144ETR can serve as a functional upgrade to BC856B in digital switching roles, provided the circuit uses PNP high-side topology and does not require adjustable biasing. Its integrated 47 kΩ resistors eliminate two external components, but pinout differs: BC856B uses emitter-collector-base order, while NHDTA144ETR uses input-GND-output (pin 1–2–3).
What is the meaning of the marking code 'QF%' on NHDTA144ETR?
The marking 'QF%' on NHDTA144ETR indicates the device variant within the series, where 'QF' identifies the NHDTA144ET type and '%' is a placeholder for the manufacturing site code (e.g., 'A' for Nijmegen, 'B' for Bangkok). This matches Table 5 in the official Nexperia datasheet Rev. 1.
How does the R1/R2 ratio affect switching behavior?
For NHDTA144ETR, R1 = R2 = 47 kΩ yields a 1:1 ratio, optimizing for predictable turn-on threshold and stable saturation under varying temperature. This ratio ensures VI(on) remains within -5 V to -3.3 V across -40 °C to +125 °C, preventing unintended turn-on due to leakage or noise.
