Nexperia USA Inc. NHDTC114ETVL

Overview

NHDTC114ETVL from Nexperia is an 80 V, 100 mA NPN resistor-equipped transistor (RET) in SOT23 (TO-236AB) package, integrating 10 kΩ input and 10 kΩ emitter-base bias resistors. It functions as a single-chip digital switch for IC input control and low-power load switching, with V_CEO = 80 V, I_O = 100 mA, and V_CE(sat) ≤ 100 mV at I_C = 10 mA / I_B = 0.5 mA.

For engineers reviewing the NHDTC114ETVL datasheet, NHDTC114ETVL pinout, NHDTC114ETVL application, or NHDTC114ETVL equivalent, this part serves as an AEC-Q101-qualified, space-saving replacement for discrete BJT + resistor networks in automotive body electronics, industrial I/O modules, and microcontroller interface circuits where simplified layout and reduced component count are critical.

Technical Context

This RET integrates a monolithic NPN transistor with two precision silicon-based bias resistors (R1 = 10 kΩ, R2 = 10 kΩ) on a single die. Its internal structure eliminates external base resistors, enabling direct logic-level drive from 3.3 V or 5 V MCU GPIOs without additional components.

The device operates with guaranteed V_(BR)CEO ≥ 80 V and I_CBO ≤ 100 nA, supporting robust off-state isolation in 24 V industrial control rails. Thermal resistance R_th(j-a) is 500 K/W on single-sided FR4 PCBs, defining its safe operating area under pulsed or continuous DC loads up to 100 mA.

FAQ

What is the maximum continuous collector current for NHDTC114ETVL?

The absolute maximum continuous collector current is 100 mA at T_amb ≤ 25 °C on a standard FR4 PCB with single-sided copper. Derating applies above 25 °C per Fig. 1: at 75 °C ambient, max I_C drops to ~65 mA to maintain T_j ≤ 150 °C. Pulse operation supports up to 250 mA for short durations with appropriate duty cycle limits.

Does NHDTC114ETVL require an external base resistor?

No. NHDTC114ETVL integrates both R1 (10 kΩ) and R2 (10 kΩ) internally, enabling direct connection of a logic signal to Pin 1 (input) without external bias components. This eliminates layout errors, reduces solder joints, and improves manufacturing yield compared to discrete BJT + resistor solutions.

Is NHDTC114ETVL suitable for 24 V automotive applications?

Yes. With V_CEO = 80 V and AEC-Q101 qualification, NHDTC114ETVL withstands automotive load-dump transients (up to ISO 7637-2 Pulse 5a: 87 V/100 ms) when used with appropriate input clamping. Its guaranteed I_CBO ≤ 100 nA and T_j(max) = 150 °C ensure stable operation in under-hood environments.

How does the VI(on) specification affect MCU interface design?

VI(on) = 1.8–2.5 V (typ./max) ensures reliable turn-on with 3.3 V and 5 V logic families. For 3.3 V MCUs, even worst-case VI(on) = 2.5 V leaves >0.8 V noise margin. This eliminates need for level shifters or Schmitt-trigger buffers in most digital control paths, simplifying interface design and reducing bill-of-materials cost.
