Product details
Overview
NZH3V6B,115 from Nexperia is a single Zener diode in SOD123F package, designed for precision voltage regulation and reference functions in low-power circuits. It delivers a nominal Zener voltage of 3.6 V at 20 mA, with differential resistance ≤60 Ω, reverse current ≤5 μA at 1 V, and total power dissipation up to 500 mW on FR4 PCB - used in automotive body control modules for stable sensor biasing.
For engineers reviewing the NZH3V6B,115 datasheet, NZH3V6B,115 pinout, NZH3V6B,115 application, or NZH3V6B,115 equivalent, this page provides verified electrical parameters, AEC-Q101 qualification status, thermal resistance values (250 K/W junction-to-ambient), cathode/anode terminal mapping, and direct alternatives for voltage reference design.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable reference voltage under varying load and temperature conditions. Its low differential resistance (≤60 Ω) ensures minimal voltage drift across 5–20 mA working current, and its AEC-Q101 qualification confirms robustness against automotive-grade thermal cycling and humidity stress.
The device uses planar epitaxial technology with a silicon die mounted in a molded SOD123F plastic package. Cathode identification is marked by a bar on the package surface, and thermal performance is defined for two mounting conditions: FR4 PCB (250 K/W Rth(j-a)) and ceramic Al2O3 PCB (125 K/W Rth(j-sp)).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 3.42 V to 3.78 V at IZ = 20 mA - defines tight regulation window for 3.6 V nominal reference |
| Differential Resistance rdif | ≤60 Ω - ensures <±20 mV output shift per 1 mA load change in regulation mode |
| Reverse Current IR | ≤5 μA at VR = 1 V - guarantees low leakage in standby bias networks |
| Total Power Dissipation Ptot | 500 mW on FR4 PCB (Tamb ≤ 25 °C) - supports continuous operation in compact automotive PCB layouts |
| Junction Temperature Tj | −55 °C to +150 °C - enables deployment in engine bay and cabin electronics without derating |

Pinout & Package
Package: SOD123F - surface-mount plastic package with 2 leads, 3.4–3.6 mm length, 1.0–1.2 mm width, 0.55–0.70 mm height, and cathode-marked bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal for correct PCB orientation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; reverse-biased configuration enables Zener conduction |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B3V6,115 | Zener voltage tolerance ±5% (3.42–3.78 V same), but higher rdif = 90 Ω and no AEC-Q101 qualification | Not qualified for automotive; suitable only for commercial-grade consumer power supplies | Select when cost sensitivity outweighs automotive compliance and tighter regulation is not required |
| MMSZ4685T1G | Same 3.6 V nominal, but wider VZ spread (3.42–3.98 V), rdif = 120 Ω, and only AEC-Q200 (passive) rated | Limited to non-safety-critical industrial applications due to lack of discrete semiconductor qualification | Choose for legacy designs where footprint compatibility with SOD123 is needed but automotive validation is unnecessary |
Compared with BZX384-B3V6,115 and MMSZ4685T1G, NZH3V6B,115 offers superior regulation stability (60 Ω vs. ≥90 Ω rdif) and automotive-grade reliability - critical for safety-relevant voltage references in body electronics and sensor subsystems.

FAQ
What is the maximum reverse current for NZH3V6B,115 at 1 V?
The maximum reverse current is 5 μA at VR = 1 V and Tj = 25 °C, as specified in Table 8 of the datasheet. This low leakage supports stable biasing in high-impedance sensor interfaces and minimizes quiescent power loss in battery-powered systems.
Is NZH3V6B,115 suitable for reflow soldering?
Yes - Nexperia explicitly recommends reflow soldering only for the SOD123F package. The device is qualified for standard lead-free reflow profiles (J-STD-020), and the recommended footprint (2.8 mm × 1.6 mm solder land) is published in Figure 5 of the datasheet.
How does the thermal resistance differ between FR4 and ceramic PCB mounting?
On FR4 PCB, Rth(j-a) is 250 K/W; on ceramic Al2O3 PCB, Rth(j-sp) drops to 125 K/W. This 2× improvement enables higher power handling in thermally demanding environments like engine control units when using appropriate substrate materials.
Does NZH3V6B,115 have polarity marking, and how is it identified?
Yes - the cathode is marked by a visible bar on the top surface of the SOD123F package. Pin 1 (cathode) is located at the bar end, and Pin 2 (anode) is at the opposite end, as shown in Figure 4 and Table 2 of the datasheet.
