Product details
Overview
NZH9V1B,115 from Nexperia is a single AEC-Q101-qualified Zener diode in SOD123F package, providing 8.85–9.23 V nominal Zener voltage at IZ = 20 mA, 120 Ω max differential resistance, and 0.5 μA reverse current at VR = 7 V - used for precision voltage regulation in automotive power rail monitoring circuits.
For engineers reviewing the NZH9V1B,115 datasheet, NZH9V1B,115 pinout, NZH9V1B,115 application, or NZH9V1B,115 equivalent, key selection criteria include Zener voltage tolerance (±2.5%), thermal resistance to solder point (70 K/W), AEC-Q101 qualification status, and SOD123F footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates as a two-terminal voltage reference device, clamping reverse-biased voltage at its specified VZ range with low dynamic impedance (≤120 Ω) and minimal temperature drift. It delivers stable regulation under DC or pulsed conditions up to 250 mA forward current and 500 mW steady-state dissipation on FR4 PCB.
Its AEC-Q101 qualification confirms suitability for automotive environments, with guaranteed operation across −55 °C to +150 °C ambient and junction temperatures up to 150 °C. The cathode-marked SOD123F package supports reflow-only assembly and achieves 125 K/W junction-to-solder-point thermal resistance on ceramic substrates.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (nominal) | 9.1 V at IZ = 20 mA - defines primary regulation setpoint for 12 V rail stabilization |
| VZ tolerance | ±2.5% (8.85–9.23 V) - ensures tight output voltage control without post-production trimming |
| rdif | ≤120 Ω - maintains low output impedance for stable regulation under load transients |
| IR @ VR = 7 V | ≤0.5 μA - guarantees minimal leakage during standby or undervoltage detection modes |
| Ptot (FR4) | 500 mW @ Tamb ≤ 25 °C - sets maximum continuous power handling on standard PCBs |
| Rth(j-sp) | 70 K/W - enables accurate thermal modeling of cathode-tab heat path in layout planning |

Pinout & Package
SOD123F surface-mount plastic package: 2.5–2.7 mm length × 1.0–1.2 mm width × 0.9–1.1 mm height; cathode marked by bar; optimized for automated placement and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal; primary heat path to PCB via cathode tab |
| 2 | Anode (A) | Connected to reference or input rail; reverse-biased configuration establishes Zener breakdown voltage |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22 |
| Low differential resistance | 120 Ω max ensures <10 mV output shift per 1 mA load change - critical for sensor biasing stability |
| SOD123F footprint | 0.55–0.70 mm pitch, 1.5–1.7 mm anode-cathode span - fits 0805-class routing density with 0.35 mm pad clearance |
| Thermal performance | 70 K/W junction-to-solder-point resistance enables >300 mW usable power on thermally enhanced pads |
| Reverse leakage control | 0.5 μA max at 7 V allows use in ultra-low-power wake-up circuits without battery drain penalties |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C9V1,215 | VZ = 8.8–9.4 V (±5%), rdif ≤ 200 Ω, Ptot = 300 mW, SOT23 package | Higher Zener impedance and lower power rating limit use in high-current regulation | Select when board space permits SOT23 and AEC-Q101 is not required |
| MMSZ5240B-TP | VZ = 8.9–9.3 V (±5%), rdif ≤ 150 Ω, Ptot = 500 mW, SOD123 package (non-flat lead) | SOD123 lacks flat-lead profile - reduces solder joint reliability in thermal cycling environments | Prefer only for non-automotive designs where thermal cycling stress is absent |
Compared with BZX84-C9V1,215 and MMSZ5240B-TP, NZH9V1B,115 offers tighter voltage tolerance, lower dynamic impedance, and AEC-Q101 validation - making it the sole choice for automotive-grade 9.1 V reference where long-term drift and thermal robustness are design-critical.

FAQ
What is the maximum continuous reverse current the NZH9V1B,115 can sustain without degradation?
The NZH9V1B,115 has no defined maximum continuous reverse current rating - its safe operating area is governed by power dissipation limits. At 9.1 V Zener voltage, sustained reverse current must remain ≤55 mA to stay within the 500 mW FR4 PCB rating. Exceeding this risks thermal runaway due to junction temperature rise beyond 150 °C.
Does the SOD123F package support hand-soldering during prototyping?
No - the datasheet explicitly states "reflow soldering is the only recommended soldering method" for the SOD123F package. Hand-soldering risks thermal damage due to localized overheating and insufficient cathode-tab wetting; hot-air rework stations with profiled ramp/soak/reflow cycles are required for reliable assembly.
How does the 0.5 μA reverse leakage at 7 V impact low-power battery monitoring circuits?
This leakage value ensures the diode draws less than 0.5 μA from a 7 V source - negligible in systems powered by coin cells or Li-ion batteries, where sleep-mode currents target sub-μA levels. It avoids measurable battery drain over multi-year deployments in portable medical or IoT edge sensors.
Is the NZH9V1B,115 suitable for use in CAN bus power domains?
No - the NZH9V1B,115 is a passive Zener diode, not a CAN transceiver, interface IC, or bus protector. While it may regulate auxiliary 9.1 V rails powering CAN controllers, it provides no bus-level ESD protection, common-mode rejection, or differential signaling capability required for direct CAN bus connection.
