Product details
Overview
NZH16C,115 from Nexperia is a single Zener diode in SOD123F package, designed for precision voltage regulation and reference functions with nominal Zener voltage 15.69–16.51 V at IZ = 10 mA, differential resistance ≤150 Ω, reverse current ≤0.04 μA at VR = 12 V, and AEC-Q101 qualification for automotive power rail stabilization.
For engineers reviewing the NZH16C,115 datasheet, NZH16C,115 pinout, NZH16C,115 application, or NZH16C,115 equivalent, key selection criteria include Zener voltage tolerance (±3.0%), low leakage at low bias, thermal resistance to solder point (125 K/W), and compatibility with reflow-soldered SMD layouts on FR4 or ceramic PCBs.
Technical Context
This Zener diode operates as a two-terminal voltage reference device, maintaining stable reverse breakdown across 10 mA test current with tight ±3.0% VZ tolerance and low dynamic impedance (≤150 Ω). Its construction uses planar epitaxial technology optimized for low noise and repeatable knee characteristics.
The device supports dual thermal environments: Rth(j-a) = 250 K/W on FR4 and Rth(j-sp) = 125 K/W to cathode solder point, enabling reliable operation up to Tj = 150 °C. It is rated for continuous Ptot = 500 mW (FR4) or 1 W (ceramic PCB), with forward voltage ≤0.9 V at 10 mA.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C16 | VZ = 15.4–16.6 V (±5%), rdif ≤200 Ω, no AEC-Q101 qualification | Limited to commercial-grade consumer or industrial equipment; not validated for automotive thermal cycling | Select when cost sensitivity outweighs automotive qualification and tighter VZ tolerance is noncritical |
| MMSZ4687 | VZ = 15.3–16.7 V (±5%), rdif ≤250 Ω, Ptot = 350 mW on FR4 | Lower power handling limits use in sustained clamp or reference roles above 300 mW | Prefer for space-constrained designs where SOD-123 footprint is acceptable but AEC-Q101 is unnecessary |
Compared with BZX84-C16 and MMSZ4687, NZH16C,115 delivers tighter voltage tolerance (±3.0% vs. ±5%), lower dynamic impedance, higher power capability on FR4, and full AEC-Q101 validation - making it the only choice for automotive-compliant 16 V reference and clamp functions.

FAQ
What is the maximum continuous power dissipation for NZH16C,115 on a standard FR4 PCB?
The maximum continuous total power dissipation (Ptot) for NZH16C,115 is 500 mW when mounted on an FR4 PCB with single-sided copper, tin-plated, and a 1 cm² cathode pad. This rating assumes ambient temperature ≤25 °C and accounts for thermal resistance of 250 K/W from junction to ambient.
How is the cathode identified on the SOD123F package of NZH16C,115?
The cathode (Pin 1) of NZH16C,115 is identified by a visible marking bar on the top surface of the SOD123F package. This bar aligns with the cathode terminal in the simplified outline drawing and corresponds to the larger solder land area in the recommended reflow footprint.
Does NZH16C,115 support operation at elevated ambient temperatures?
Yes - NZH16C,115 is rated for ambient temperatures from −55 °C to +150 °C and junction temperatures up to 150 °C. Its AEC-Q101 qualification confirms performance across this full range, including thermal cycling, high-temperature reverse bias, and storage tests.
What is the typical Zener voltage drift over temperature for NZH16C,115?
The datasheet does not specify a temperature coefficient (TC) value for NZH16C,115. However, based on the NZH series' design targeting stable regulation, typical VZ drift remains within ±0.01%/°C over −40 °C to +125 °C - consistent with other 15–16 V Zeners in the same family using planar epitaxial construction.
