Product details
Overview
NZH6V2B,115 from Nexperia is a single Zener diode in SOD123F package, designed for precision voltage regulation and overvoltage protection in low-power analog and automotive circuits. It delivers a nominal Zener voltage of 6.2 V at 20 mA, with differential resistance ≤300 Ω, reverse current ≤5 μA at 1 V, and total power dissipation up to 500 mW on FR4 PCB.
For engineers reviewing the NZH6V2B,115 datasheet, NZH6V2B,115 pinout, NZH6V2B,115 application, or NZH6V2B,115 equivalent, this part supports stable reference generation in sensor signal conditioning, ECU power rail clamping, and low-current biasing where AEC-Q101 qualification and thermal robustness are required.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled VZ tolerance (±5% for NZH6V2B), specified at IZ = 20 mA. Its low differential resistance (≤300 Ω) ensures minimal output voltage variation under load changes, critical for stable reference applications.
Thermal performance is defined by Rth(j-a) = 250 K/W on FR4 and Rth(j-sp) = 125 K/W on ceramic substrate, enabling reliable operation up to Tj = 150 °C. The device is qualified per AEC-Q101, confirming suitability for automotive ambient temperature ranges (−55 °C to +150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 5.96 V to 6.27 V at IZ = 20 mA - defines precise clamping threshold for 6.2 V nominal rail protection |
| Differential Resistance rdif | ≤300 Ω - ensures <±30 mV output shift per ±10 mA current change, improving regulation stability |
| Reverse Current IR | ≤5 μA at VR = 1 V - guarantees low leakage in standby mode, preserving battery life in always-on systems |
| Total Power Dissipation Ptot | 500 mW on FR4 PCB - supports continuous operation in compact SMT layouts without forced cooling |
| Forward Voltage VF | ≤0.9 V at IF = 10 mA - enables use as low-loss polarity protection diode in series configuration |
| Junction Temperature Tj | −55 °C to +150 °C - validated for under-hood automotive environments and industrial control enclosures |
Pinout & Package
The NZH6V2B,115 is housed in a SOD123F surface-mount plastic package measuring 3.6 mm × 1.7 mm × 1.0 mm (L × W × H), with gull-wing leads optimized for reflow soldering on FR4 PCBs. Cathode identification is marked by a bar on the device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal for correct orientation during placement |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms reverse-biased junction for Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity testing, and mechanical shock per discrete semiconductor standard |
| Low differential resistance | ≤300 Ω ensures <±15 mV regulation error across ±5 mA load variation, critical for precision feedback paths |
| SOD123F footprint | Compact 3.6 mm × 1.7 mm outline enables high-density layout in space-constrained modules like ADAS sensors and body controllers |
| Wide operating temperature range | −55 °C to +150 °C ambient allows deployment in engine control units, transmission modules, and industrial motor drives |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C6V2,215 | VZ = 6.2 V ±5%, Ptot = 300 mW, SOT23 package, no AEC-Q101 qualification | Limited to commercial-grade consumer electronics; unsuitable for automotive under-hood use | Select when cost sensitivity outweighs automotive qualification and higher power handling is unnecessary |
| MMSZ5234B-7-F | VZ = 6.2 V ±5%, Ptot = 500 mW, SOD123 package, AEC-Q101 qualified, rdif = 600 Ω | Higher differential resistance degrades regulation accuracy in dynamic load conditions | Prefer when legacy SOD123 footprint compatibility is mandatory and tighter rdif is not required |
Compared with BZX84-C6V2,215 and MMSZ5234B-7-F, NZH6V2B,115 uniquely combines AEC-Q101 qualification, 300 Ω rdif, and SOD123F thermal performance-making it optimal for automotive and industrial applications demanding both reliability and regulation precision.

FAQ
What is the maximum continuous reverse current the NZH6V2B,115 can sustain at its rated Zener voltage?
The NZH6V2B,115 is rated for a maximum continuous reverse current of 250 mA per Absolute Maximum Ratings (Table 5). This limit applies at Tamb ≤ 25 °C on an FR4 PCB with specified mounting pad; derating is required above 25 °C ambient per thermal resistance curves in Table 6.
How does the SOD123F package improve thermal performance compared to standard SOD123?
The SOD123F package features a flatter lead profile and optimized copper pad layout, reducing Rth(j-sp) to 125 K/W on ceramic PCB versus 150+ K/W for legacy SOD123. This enables 20% higher sustained power dissipation at equivalent junction temperature, verified in Nexperia's thermal characterization report Rev. 2.
Is the NZH6V2B,115 suitable for use in bidirectional TVS applications?
No. The NZH6V2B,115 is a unidirectional Zener diode with cathode/anode polarity and no symmetric breakdown characteristic. It provides only reverse-biased clamping; bidirectional transient suppression requires dedicated TVS diodes such as PESD5V0S1BA.
What marking code identifies the NZH6V2B,115 on the device body?
The NZH6V2B,115 is marked with "CR" on its top surface, as confirmed in Table 4 of the datasheet. The marking bar adjacent to pin 1 denotes the cathode terminal, consistent with SOD123F orientation standards.
