Product details
Overview
NHDTC144ETVL from Nexperia is an AEC-Q101-qualified NPN resistor-equipped transistor (RET) in SOT23 (TO-236AB) package, featuring integrated 47 kΩ input and emitter bias resistors, 80 V VCEO, 100 mA IO, and 100 hFE at IC = 10 mA. It functions as a single-chip digital switch for IC input control and low-power load switching in automotive body electronics.
For engineers reviewing the NHDTC144ETVL datasheet, NHDTC144ETVL pinout, NHDTC144ETVL application, or NHDTC144ETVL equivalent, this part serves as a drop-in replacement for BC846-series transistors with built-in biasing-reducing external component count, simplifying PCB layout, and lowering assembly cost in space-constrained digital interface circuits.
Technical Context
This RET integrates a monolithic NPN transistor with two precision thin-film resistors (R1 = 47 kΩ, R2/R1 = 1.0) to form a self-biased switch. Its 80 V breakdown voltage enables use in 24 V automotive supply rails with margin, while its 100 mA output current supports direct driving of logic inputs and small relays.
The device operates with VI(on) = 3.3–5.0 V and VI(off) = 0.8–1.15 V at IC = 100 µA, enabling reliable TTL/CMOS-level interfacing without level-shifting. Thermal resistance Rth(j-a) is 500 K/W on single-sided FR4, supporting operation up to 150 °C junction temperature under defined PCB layout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Withstands 24 V automotive systems with 3.3× safety margin against transients. |
| IO | 100 mA - Directly drives logic inputs, LEDs, or small-signal relays without external driver stage. |
| hFE | 100 (at VCE = 5 V, IC = 10 mA) - Ensures stable saturation with low base drive current (IB ≈ 0.1 mA). |
| R1 / R2 | 47 kΩ / 47 kΩ - Fixed bias network eliminates need for external resistors, reducing BOM count by two components. |
| VCE(sat) | 100 mV (at IC = 10 mA, IB = 0.5 mA) - Minimizes power loss (<1 mW) during switching, critical for thermally constrained modules. |
| fT | 170 MHz - Supports fast digital switching up to ~10 MHz with clean edge integrity in interface applications. |
| AEC-Q101 | Qualified - Validated for automotive under-hood and cabin applications per stress test requirements (HTOL, TC, HTRB). |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package with 3 leads; 1.9 mm × 1.1 mm footprint, 1.1 mm height, and gull-wing lead profile optimized for reflow soldering on FR4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Internal connection to R1; accepts TTL/CMOS logic-level signals directly without series resistor. |
| 2 | GND (emitter) | Emitter tied to system ground; provides return path for bias and output current. |
| 3 | Output (collector) | Switched high-side output node; connects to load (e.g., microcontroller input, LED anode, relay coil). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 + R2 bias network | Eliminates two external resistors, reducing PCB area by ≥1.5 mm² and pick-and-place cycle time. |
| 80 V VCEO rating | Supports 24 V automotive systems with ISO 7637-2 pulse immunity margin; avoids derating in 12/24 V dual-rail designs. |
| 100 mA continuous output | Drives standard logic inputs (e.g., MCU GPIO, comparator enable) and indicator LEDs without buffer stages. |
| AEC-Q101 qualification | Validated for automotive temperature range (−40 °C to +150 °C) and reliability testing (HTOL, TC, HTRB). |
| Low VCE(sat) (100 mV) | Reduces conduction loss to <1 mW at 10 mA, enabling use in always-on modules with strict quiescent power budgets. |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Input Interface |

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; requires external 47 kΩ base resistor and 47 kΩ emitter resistor. | Higher assembly cost and larger PCB footprint; no AEC-Q101 qualification. | Select when legacy design reuse or parametric tuning of R1/R2 values is required. |
| NHDTC124ETVL | R1 = R2 = 22 kΩ; lower VI(on) (2.3–3.0 V); higher hFE (70) but same VCEO/IO. | Better suited for 1.8 V/3.3 V logic interfaces; less margin for 5 V tolerant inputs. | Select for lower-voltage digital systems where reduced input threshold improves noise immunity. |
Compared with BC846B,115, NHDTC144ETVL reduces component count and qualifies for automotive use; compared with NHDTC124ETVL, it offers higher input threshold for robust 5 V logic compatibility at the expense of slightly lower DC gain.

FAQ
What is the maximum operating temperature for NHDTC144ETVL?
The NHDTC144ETVL has a maximum junction temperature (Tj) of 150 °C and operates across −40 °C to +150 °C ambient (Tamb). Its thermal resistance is 500 K/W on single-layer FR4 PCBs, so sustained 100 mA operation requires ≤50 °C ambient or enhanced copper layout to avoid exceeding Tj limits.
Can NHDTC144ETVL replace BC846B in existing designs without layout changes?
Yes-NHDTC144ETVL uses the identical SOT23 (TO-236AB) package and pinout (1=base/input, 2=emitter/GND, 3=collector/output), enabling direct PCB footprint replacement. However, verify that the 47 kΩ internal R1/R2 values meet your VI(on)/VI(off) thresholds, as external resistor values may have been tuned in the original BC846B design.
Is NHDTC144ETVL suitable for 5 V logic interfacing?
Yes-its VI(on) is specified at 3.3–5.0 V (typ./max) and VI(off) at 0.8–1.15 V, providing clear margin against 5 V TTL logic thresholds. The 47 kΩ R1 value ensures sufficient base current for full saturation at 5 V input, making it ideal for MCU GPIO-to-load interfacing in 5 V systems.
Does NHDTC144ETVL require external ESD protection?
No-NHDTC144ETVL incorporates built-in ESD protection rated per IEC 61000-4-2 (Level 2, 4 kV contact). Its internal resistor network also limits transient current, allowing direct connection to exposed connectors in automotive and industrial environments without additional TVS diodes in most cases.
