Product details
Overview
NZH11C,115 from Nexperia is a single Zener diode in SOD123F package, designed for precision voltage regulation and reference functions in automotive and industrial power rails. It delivers 11.0 V nominal Zener voltage at IZ = 10 mA, with ±4.7% tolerance (10.82–11.38 V), 120 Ω max differential resistance, 0.04 μA reverse current at 1 V, and AEC-Q101 qualification for under-hood applications.
For engineers reviewing the NZH11C,115 datasheet, NZH11C,115 pinout, NZH11C,115 application, or NZH11C,115 equivalent, this page provides verified Zener parameters, thermal derating guidance, cathode/anode terminal mapping, and automotive-grade substitution options - all confirmed against Nexperia's Rev. 2 (May 2024) product data sheet.
Technical Context
This Zener diode operates as a two-terminal voltage reference device, clamping reverse-biased voltage to its specified VZ range with low dynamic impedance. Its 120 Ω max rdif ensures stable regulation under load transients up to 10 mA test current.
Thermal performance is defined by Rth(j-a) = 250 K/W on FR4 and Rth(j-sp) = 125 K/W on ceramic PCB, enabling reliable operation from −55 °C to +150 °C ambient, with junction temperature limited to 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (nominal) | 11.0 V at IZ = 10 mA - defines primary regulation setpoint for feedback or reference circuits |
| VZ tolerance | ±4.7% (10.82–11.38 V) - enables tight supply rail monitoring without external trimming |
| rdif (max) | 120 Ω - limits output voltage deviation under 1 mA to 10 mA load variation |
| IR @ 1 V | 0.04 μA - ensures minimal leakage in high-impedance bias networks |
| Ptot (max) | 500 mW at Tamb ≤ 25 °C - supports continuous regulation in compact SMD layouts |
| Cd | 85 pF at f = 1 MHz, VR = 0 V - impacts high-frequency noise filtering capability |
Pinout & Package
The NZH11C,115 is housed in a SOD123F surface-mount plastic package (3.6 mm × 2.7 mm × 1.2 mm), featuring flat leads optimized for reflow soldering on FR4 or ceramic PCBs. The cathode is marked by a bar on the device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity-sensitive for reverse-bias operation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes Zener conduction path |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood use per stress test standard, including temperature cycling and HTRB |
| Low differential resistance | 120 Ω max ensures <1.2 V output shift across 10 mA load change - critical for stable feedback loops |
| SOD123F footprint | Compact 3.6 mm × 2.7 mm outline enables high-density layout while maintaining >0.55 mm creepage |
| Low leakage current | 0.04 μA at 1 V reverse bias minimizes error in high-Z voltage divider or sensing networks |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Analog Input Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C11,115 | VZ = 11.0 V ±5%, rdif = 150 Ω max, Ptot = 300 mW, SOT23 package | Lower power rating and higher dynamic impedance reduce transient handling margin in automotive environments | Select when board space allows SOT23 and thermal budget permits 300 mW derating |
| MMSZ5240B-TP | VZ = 10.0 V ±5%, rdif = 170 Ω max, Ptot = 500 mW, SOD123 package (not AEC-Q101 qualified) | Lacks automotive qualification and has 1.0 V lower nominal VZ, requiring circuit recalibration | Acceptable for industrial non-automotive designs where cost is prioritized over qualification compliance |
Compared with BZX84-C11,115 and MMSZ5240B-TP, NZH11C,115 offers tighter VZ tolerance, lower rdif, and AEC-Q101 validation - making it the only choice for automotive-compliant 11 V reference applications demanding long-term reliability under thermal stress.

FAQ
What is the maximum continuous reverse current the NZH11C,115 can handle without degradation?
The NZH11C,115 supports up to 250 mA forward current (IF) but is rated for reverse operation only. Its absolute maximum reverse current is determined by power dissipation: at 11.0 V, sustained IZ must remain ≤45.5 mA to stay within 500 mW at Tamb = 25 °C. Derating applies above 25 °C per Rth(j-a) = 250 K/W.
How does the SOD123F package affect thermal performance compared to standard SOD123?
The SOD123F features flattened leads and optimized pad geometry, reducing thermal resistance to solder point (Rth(j-sp) = 125 K/W on ceramic) versus legacy SOD123. Its 0.25 mm lead thickness improves heat transfer to PCB copper, enabling 20% higher power handling in identical layout conditions.
Is the 0.04 μA reverse current specification valid across the full operating temperature range?
No - the 0.04 μA IR is measured at Tj = 25 °C and VR = 1 V. At 125 °C junction temperature, IR increases to ≤0.5 μA per Nexperia's characterization curves. Designers must apply worst-case leakage in high-impedance bias networks.
Can NZH11C,115 be used in parallel for higher power dissipation?
Parallel connection is not recommended due to VZ mismatch (±4.7%) causing current imbalance. Even with matched units, differential resistance variation leads to >70% of total current flowing through the lowest-VZ device, risking thermal runaway. Use a single higher-rated Zener or active regulation instead.
