Product details
Overview
NHDTC143ZTR from Nexperia is an AEC-Q101-qualified NPN resistor-equipped transistor (RET) in SOT23 package, designed for digital switching applications with 80 V VCEO, 100 mA IO, and integrated 4.7 kΩ/47 kΩ bias resistors. It replaces discrete BJT + base-resistor combinations in load control and IC input interfacing.
For engineers reviewing the NHDTC143ZTR datasheet, NHDTC143ZTR pinout, NHDTC143ZTR application, or NHDTC143ZTR equivalent, this page delivers verified electrical parameters, thermal derating curves, input voltage thresholds (VI(on) = 1.4 V typ, VI(off) = 625 mV typ), and automotive-grade reliability data - all confirmed from Nexperia's official Rev. 1 product data sheet.
Technical Context
This RET integrates a monolithic NPN transistor with two precision laser-trimmed on-die resistors: R1 = 4.7 kΩ (input bias) and R2 = 47 kΩ (base-emitter feedback), forming a fixed-current-input configuration that eliminates external bias components. Its 80 V breakdown rating enables use in 24 V industrial and 12 V automotive supply rails.
The device operates with guaranteed DC current gain (hFE ≥ 100 at IC = 10 mA, VCE = 5 V) and low saturation voltage (VCE(sat) ≤ 100 mV at IC = 10 mA, IB = 0.5 mA), supporting fast, low-loss switching in logic-level driven circuits without external level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Supports reliable operation in 24 V systems with margin against transients and inductive kickback. |
| IO | 100 mA - Sufficient drive capability for LED arrays, small relays, and logic inputs without external amplification. |
| R1 / R2 | 4.7 kΩ / 47 kΩ - Fixed internal bias network simplifies PCB layout and reduces bill-of-materials count by one resistor. |
| VI(on) | 1.4 V (typ) - Compatible with 1.8 V and 3.3 V logic families for direct microcontroller GPIO interfacing. |
| VI(off) | 625 mV (typ) - Ensures robust noise immunity and prevents false turn-on in noisy environments. |
| Ptot | 350 mW (4-layer PCB) - Enables continuous switching in compact SOT23 footprint without forced cooling. |
| AEC-Q101 | Qualified - Validated for automotive under-hood and body-control module applications per stress test standard. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package: 3-pin, 1.3 mm × 2.9 mm × 1.0 mm body, gull-wing leads, JEDEC-compliant footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level voltage to activate transistor - no external base resistor required. |
| 2 | GND (emitter) | Emitter tied directly to ground reference; serves as common return path for load current and bias network. |
| 3 | Output (collector) | Switched high-side output node; connects to load (e.g., LED anode or relay coil) with up to 100 mA sink capability. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistors | Eliminates need for external RB, reducing component count and PCB area while improving assembly yield. |
| 80 V breakdown rating | Enables safe operation in 24 V industrial control and 12 V automotive power domains with transient headroom. |
| 100 mA output current | Directly drives medium-power loads such as indicator LEDs, optocoupler inputs, and small-signal relays. |
| AEC-Q101 qualification | Validated for automotive temperature range (−40 °C to +150 °C) and mechanical stress, supporting Tier-1 designs. |
| Low VCE(sat) | ≤100 mV at rated current minimizes conduction loss and self-heating in battery-powered and thermally constrained systems. |
Applications
| Automotive Body Control | Industrial PLC I/O |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC846B,115 | Discrete NPN BJT without integrated resistors; requires external 10 kΩ base resistor for equivalent biasing. | Lacks built-in noise immunity and VI(off) specification; less suitable for noisy automotive environments. | Select when board space allows discrete biasing and cost sensitivity outweighs AEC-Q101 compliance needs. |
| NHDTC123JTR | R1 = 2.2 kΩ (vs. 4.7 kΩ); lower input threshold (VI(on) = 1.2 V typ) but reduced noise margin (VI(off) = 595 mV). | Better suited for 1.8 V logic interfaces but less robust in electrically harsh settings like engine bays. | Choose for ultra-low-voltage MCU compatibility where higher noise immunity is not required. |
Compared with BC846B,115, NHDTC143ZTR reduces component count and improves system-level noise immunity; compared with NHDTC123JTR, it trades slightly higher VI(on) for superior VI(off) margin - making it optimal for 3.3 V automotive I/O and industrial 24 V signal conditioning.

FAQ
What is the maximum continuous collector current for NHDTC143ZTR?
The absolute maximum continuous collector current is 100 mA under standard conditions (Tamb ≤ 25 °C, FR4 PCB with 4-layer copper). Derating applies above 25 °C per Figure 1: at 85 °C ambient, maximum sustainable current drops to ~220 mA only if Ptot remains within 350 mW limit - but practical design limits remain at 100 mA to ensure long-term reliability and thermal safety.
Does NHDTC143ZTR require an external base resistor?
No. NHDTC143ZTR integrates R1 = 4.7 kΩ and R2 = 47 kΩ internally, forming a complete bias network. Applying logic voltage directly to Pin 1 activates the transistor - no external base resistor is needed, reducing component count and eliminating associated layout errors.
How does the VI(off) specification improve noise immunity?
VI(off) = 625 mV (typ) defines the maximum input voltage at which the transistor remains reliably off. This 625 mV threshold provides >200 mV margin above typical CMOS logic low levels (<400 mV), preventing false triggering from EMI, crosstalk, or ground bounce in automotive and industrial environments.
Is NHDTC143ZTR compatible with lead-free reflow soldering?
Yes. NHDTC143ZTR uses standard SnAgCu (SAC305) compatible terminations and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1). The recommended reflow profile follows IPC/JEDEC J-STD-020D: peak temperature 260 °C, time above liquidus 60–150 seconds, with full thermal validation provided in Nexperia's SOT23 reflow footprint documentation (Figure 25).
