Product details
Overview
NZH13B,115 from Nexperia is a single Zener diode in SOD123F package, designed for precision voltage regulation and overvoltage protection in automotive and industrial power rails. It delivers a nominal Zener voltage of 13.0 V (min 12.35 V, max 13.65 V at IZ = 10 mA), with differential resistance ≤110 Ω, reverse current ≤0.04 μA at 10 V, and AEC-Q101 qualification for under-hood applications.
For engineers reviewing the NZH13B,115 datasheet, NZH13B,115 pinout, NZH13B,115 application, or NZH13B,115 equivalent, key selection criteria include Zener voltage tolerance, low leakage at bias voltages below VZ, thermal resistance to ambient (250 K/W on FR4), junction temperature rating (150 °C), and SOD123F footprint compatibility with automated reflow assembly.
Technical Context
This Zener diode operates in reverse breakdown mode to clamp transient overvoltages and stabilize reference nodes. Its low differential resistance (≤110 Ω) ensures tight regulation across load variations, while its 0.04 μA reverse current at 10 V enables ultra-low standby power loss in always-on circuits.
The device is qualified per AEC-Q101 and rated for operation from −55 °C to +150 °C ambient, with thermal resistance from junction to solder point at 125 K/W on ceramic PCB - critical for sustained power dissipation in compact automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 12.35 V to 13.65 V at IZ = 10 mA - defines clamping threshold with ±5% tolerance for stable rail supervision |
| Differential Resistance rdif | ≤110 Ω - ensures minimal output voltage shift under dynamic current changes in feedback loops |
| Reverse Current IR | ≤0.04 μA at VR = 10 V - enables negligible quiescent current in battery-backed monitoring circuits |
| Forward Voltage VF | ≤0.9 V at IF = 10 mA - supports use as polarity-sensitive protection element in bidirectional interfaces |
| Thermal Resistance Rth(j-a) | 250 K/W on FR4 PCB - determines maximum continuous power (500 mW) before exceeding 150 °C junction limit |
| Junction Temperature Tj | −55 °C to +150 °C - validated for engine control unit (ECU) and body electronics mounting locations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C13 | Same 13 V nominal VZ, but SOT23 package (higher Rth(j-a) = 300 K/W), no AEC-Q101 qualification | Limited to commercial-grade consumer products; unsuitable for automotive under-hood environments | Select when cost is primary constraint and thermal derating allows 300 mW max on FR4 |
| MMSZ5242B | 13 V VZ with tighter ±5% tolerance, but higher rdif (130 Ω) and no automotive qualification | Used in telecom power supplies where long-term drift matters more than transient response | Prefer for non-automotive designs requiring tighter initial tolerance but accepting higher impedance |
Compared with BZX84-C13 and MMSZ5242B, NZH13B,115 provides lower thermal resistance, guaranteed AEC-Q101 stress testing, and superior differential resistance - making it the only choice for automotive power rail supervision where reliability and regulation fidelity are co-constrained.

FAQ
What is the maximum continuous power dissipation for NZH13B,115 on standard FR4 PCB?
The maximum continuous power dissipation is 500 mW at ambient temperature ≤25 °C when mounted on FR4 PCB with single-sided copper and 1 cm² cathode pad. Derating is required above 25 °C at 4.0 mW/°C based on Rth(j-a) = 250 K/W.
Is NZH13B,115 suitable for bidirectional transient suppression?
No - NZH13B,115 is a unidirectional Zener diode optimized for reverse-bias regulation. Forward conduction is limited to ≤0.9 V at 10 mA; it lacks symmetrical clamping capability and must be paired with a series diode or TVS for bidirectional protection.
How does the 0.04 μA reverse current impact low-power system design?
This ultra-low leakage enables direct connection to battery-backed circuits without measurable discharge - for example, sustaining a 200 mAh coin cell for >5 years in sleep mode while monitoring a 13 V threshold, assuming 100% duty-cycle sampling every 10 seconds.
Can NZH13B,115 replace TL431 in shunt regulator applications?
Only in simple fixed-voltage cases: NZH13B,115 provides passive 13 V regulation without adjustable feedback or current-sink capability. It lacks the TL431's 2.5 V reference, programmable output, and 100 mA sink current - so it suits basic clamping, not active regulation loops.
