Product details

Overview

NZH4V7B,115 from Nexperia is a single Zener diode in SOD123F package, designed for precision voltage regulation and reference functions in low-power analog circuits. It delivers a nominal Zener voltage of 4.7 V at I_Z = 20 mA, with differential resistance ≤25 Ω, reverse current ≤5 μA at V_R = 1 V, and total power dissipation up to 500 mW (FR4 PCB) or 1 W (ceramic PCB). It is AEC-Q101 qualified for automotive board-level regulation.

For engineers reviewing the NZH4V7B,115 datasheet, NZH4V7B,115 pinout, NZH4V7B,115 application, or NZH4V7B,115 equivalent, this page provides verified Zener voltage tolerance (±5.3%), thermal resistance (250 K/W junction-to-ambient), cathode/anode polarity marking, and automotive-grade reliability data - all critical for ESD-protected LDO biasing, sensor reference stabilization, and overvoltage clamp design.

Technical Context

This Zener diode operates as a two-terminal voltage reference device, conducting in reverse breakdown when V_R ≥ V_Z, with stable regulation maintained across I_Z = 1 mA to 20 mA. Its low differential resistance (25 Ω max) ensures minimal output voltage variation under load changes, while its 300 pF capacitance at 1 MHz supports moderate-frequency noise suppression without compromising transient response.

The SOD123F package enables high-density surface-mount placement with defined thermal path to solder pad (R_th(j-sp) = 125 K/W on ceramic), and the cathode bar marking aligns with JEDEC-standard polarity identification. AEC-Q101 qualification confirms robustness against temperature cycling, humidity, and mechanical stress in automotive ambient conditions (−55 °C to +150 °C).

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage V_Z	4.55 V to 4.80 V at I_Z = 20 mA - tight ±5.3% tolerance enables accurate 4.7 V reference without external trimming
Differential Resistance r_dif	≤25 Ω - ensures <125 mV output shift per 5 mA load change, critical for stable bias networks
Reverse Current I_R	≤5 μA at V_R = 1 V - guarantees low leakage in standby mode for battery-powered sensors
Power Dissipation P_tot	500 mW (FR4 PCB) / 1 W (Al₂O₃ PCB) - defines maximum continuous regulation capability under real board thermal conditions
Junction Temperature T_j	−55 °C to +150 °C - supports operation in engine bay and powertrain control units
Capacitance C_d	300 pF at f = 1 MHz, V_R = 0 V - limits high-frequency impedance rise, aiding RF decoupling in mixed-signal systems

Pinout & Package

SOD123F is a 2-pin surface-mount plastic package measuring 3.5 mm × 1.6 mm × 1.1 mm (L × W × H), with gull-wing leads and cathode-side marking bar. Thermal performance is optimized via cathode tab soldering to ≥1 cm² copper pad on FR4 or ceramic substrates.

Pin/Terminal	Circuit Role	Design Meaning
1	Cathode (K)	Connected to regulated output node; marked by bar on package top; carries reverse-bias current during regulation
2	Anode (A)	Connected to ground or lower-potential rail; completes Zener conduction path when reverse voltage exceeds V_Z

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive applications including powertrain and body electronics per stress test requirements

Small SOD123F footprint	3.5 mm × 1.6 mm area enables placement in space-constrained modules like ABS ECUs and LED drivers
Wide operating temperature	−55 °C to +150 °C ambient rating supports under-hood deployment without derating

Applications

Automotive Sensor Reference

IC Role / Device Role / Timing Role: Zener diode acts as precision shunt reference, replacing higher-cost bandgap ICs in cost-sensitive designs.

Use Value: Tight V_Z tolerance (±5.3%) and low r_dif maintain sensor accuracy across −40 °C to +125 °C without calibration.

Use Scenario: Setting feedback voltage for adjustable LDOs in infotainment power rails.

IC Role / Device Role / Timing Role: Shunt-connected Zener establishes precise V_REF at FB pin, enabling accurate output voltage programming.

Use Value: 500 mW power rating allows direct use with common 10–20 mA divider currents, eliminating need for series resistor scaling.

Overvoltage Clamp

ESD Protection Interface

Use Scenario: Clamping transients on 5 V microcontroller I/O lines exposed to inductive switching noise.

IC Role / Device Role / Timing Role: Reverse-biased Zener conducts above 4.8 V, limiting voltage excursion to protect CMOS inputs.

Use Value: 25 Ω r_dif ensures clamped voltage stays below 5.1 V at 100 mA surge, meeting IEC 61000-4-4 Level 3 immunity.

Use Scenario: Secondary protection stage for USB-C CC line in automotive telematics modules.

IC Role / Device Role / Timing Role: Low-capacitance (300 pF) Zener absorbs ESD pulses while preserving signal integrity up to 10 Mbps.

Use Value: 5 μA leakage at 1 V ensures negligible impact on CC line biasing, avoiding false plug detection.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener regulation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX584C4V7	V_Z = 4.7 V ±5%, r_dif = 90 Ω (max), P_tot = 300 mW, SOD-323 package	Higher differential resistance increases regulation error; lower power rating requires current limiting	Select when board space is tighter (SOD-323 is smaller) and thermal margin is sufficient
MMSZ4704T1G	V_Z = 4.7 V ±5%, r_dif = 40 Ω (max), P_tot = 500 mW, SOD-123 package (non-flat lead)	Slightly higher r_dif; identical power but less optimal thermal path due to non-flat leads	Prefer for legacy designs using standard SOD-123 footprints where reflow profile compatibility is critical

Compared with BZX584C4V7 and MMSZ4704T1G, NZH4V7B,115 offers superior regulation stability (25 Ω vs. 40–90 Ω r_dif) and AEC-Q101 qualification - making it the only choice for automotive-critical voltage references requiring both precision and reliability.

FAQ

What is the maximum reverse current for NZH4V7B,115 at 1 V?

The reverse current I_R is guaranteed ≤5 μA at V_R = 1 V and T_j = 25 °C. This low leakage ensures minimal quiescent power draw in always-on sensor bias networks and preserves battery life in automotive modules with extended sleep modes.

Is NZH4V7B,115 suitable for use in reflow soldering processes?

Yes - the SOD123F package is qualified exclusively for reflow soldering per Nexperia's footprint guidelines. The recommended profile uses peak temperatures ≤260 °C, and the flat leads ensure coplanarity and reliable joint formation on standard FR4 and ceramic PCBs.

How does the Zener voltage tolerance affect circuit accuracy?

With V_Z specified from 4.55 V to 4.80 V (±5.3% at 20 mA), the worst-case regulation deviation is ±0.25 V. For applications requiring tighter accuracy, this must be accounted for in feedback divider design or compensated via system calibration - no internal trimming is provided.

Can NZH4V7B,115 replace older NZH4V7A variants?

No - NZH4V7B has tighter V_Z tolerance (±5.3% vs. ±7.5% for NZH4V7A) and lower r_dif (25 Ω vs. 30 Ω). While functionally compatible, substitution requires verification of downstream circuit sensitivity to improved regulation stability and reduced thermal resistance.
