Product details
Overview
NZH8V2B,115 from Nexperia is a single Zener diode in SOD123F package, designed for precision voltage regulation and overvoltage protection at 8.2 V nominal Zener voltage (VZ = 8.02–8.36 V @ IZ = 20 mA), with low differential resistance (120 Ω), AEC-Q101 qualification, and 500 mW total power dissipation on FR4 PCB.
For engineers reviewing the NZH8V2B,115 datasheet, NZH8V2B,115 pinout, NZH8V2B,115 application, or NZH8V2B,115 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (Rth(j-a) = 250 K/W), reverse current (IR ≤ 0.5 μA @ VR = 6.5 V), cathode/anode polarity marking, and automotive-grade reliability validation.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its low differential resistance (120 Ω) ensures minimal voltage deviation across ±5 mA current variation around IZ = 20 mA, and its 0.5 μA max reverse leakage at 6.5 V supports low-power standby regulation.
The device uses planar epitaxial construction with silicon die in a molded plastic SOD123F package, featuring a cathode-marked bar and optimized thermal path to solder point (Rth(j-sp) = 125 K/W on ceramic PCB), enabling reliable operation up to Tj = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (nominal) | 8.2 V - precise regulation target at IZ = 20 mA, with ±2.1% tolerance (8.02–8.36 V) |
| rdif | 120 Ω - small voltage shift per mA change in Zener current, critical for stable reference accuracy |
| IR @ VR = 6.5 V | ≤ 0.5 μA - ultra-low leakage enables battery-backed or low-quiescent circuits |
| Ptot | 500 mW - maximum continuous power on FR4 PCB; derates linearly above 25 °C ambient |
| Cd @ f = 1 MHz | 150 pF - junction capacitance impacts high-frequency noise filtering and transient response |
| Tj max | 150 °C - junction temperature limit defining safe operating area under pulsed or DC stress |
Pinout & Package
SOD123F is a surface-mount, 2-lead plastic package measuring 3.6 mm × 1.7 mm × 1.0 mm (L × W × H), with gull-wing leads, flat bottom profile, and cathode marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal; carries reverse-biased current during regulation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path for Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics requiring extended temperature (-55 °C to +150 °C) and reliability compliance |
| Low differential resistance | 120 Ω ensures <±0.12 V regulation shift across ±1 mA Zener current variation, improving reference stability |
| Small SOD123F footprint | 3.6 mm × 1.7 mm area enables high-density PCB layouts while maintaining thermal performance via exposed cathode pad |
| Ultra-low reverse leakage | 0.5 μA max at 6.5 V allows use in always-on power rails without significant standby current penalty |
Applications
| Automotive ECU Voltage Reference | Industrial Sensor Signal Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C8V2,115 | Same SOD123 package, but higher rdif (200 Ω) and wider VZ tolerance (±5%), no AEC-Q101 qualification | Not suitable for automotive or high-accuracy references; acceptable for general-purpose clamping | Select when cost sensitivity outweighs regulation precision and automotive compliance requirements |
| MMSZ5233BT1G | SOD-123 package, VZ = 8.2 V, rdif = 150 Ω, IR = 1 μA @ 6.5 V, no AEC-Q101 rating | Limited to commercial-temperature industrial use; lacks automotive qualification and low-leakage advantage | Choose only if legacy design reuse or distributor stock availability drives selection over performance |
Compared with BZX84-C8V2,115 and MMSZ5233BT1G, NZH8V2B,115 delivers tighter voltage tolerance, lower leakage, and automotive-grade reliability-making it the preferred choice where reference stability, low-power operation, or automotive deployment is required.

FAQ
What is the maximum continuous Zener current for NZH8V2B,115 at 25 °C ambient?
The absolute maximum forward current is 250 mA, but continuous Zener operation is limited by power dissipation. At 25 °C ambient on FR4 PCB, Ptot = 500 mW implies IZ ≤ 60.9 mA (500 mW ÷ 8.2 V), assuming nominal VZ. Derating applies above 25 °C per Rth(j-a) = 250 K/W.
How is cathode polarity identified on the NZH8V2B,115 package?
The cathode is marked by a visible bar on the top surface of the SOD123F package, aligned with pin 1. The device outline diagram confirms pin 1 as K (cathode) and pin 2 as A (anode); this marking is laser-etched and verified per JEDEC standards for automated optical inspection.
Does NZH8V2B,115 support reflow soldering only, or can it be hand-soldered?
Reflow soldering is the only recommended method per Nexperia's documentation. Hand-soldering risks thermal damage due to localized overheating beyond the 150 °C junction limit; the SOD123F footprint is optimized for controlled reflow profiles with peak temperatures ≤ 260 °C and time-above-liquidus ≤ 60 seconds.
Is the 150 pF junction capacitance measured at zero bias or reverse bias?
The 150 pF value is measured at f = 1 MHz and VR = 0 V, per Table 8 note [1]. Capacitance decreases with increasing reverse bias; at VR = 6.5 V (80% of VZ), typical Cd drops to ~110 pF, affecting high-frequency filtering performance in transient suppression designs.
