Product details
Overview
BZV55-B4V7,115 from Nexperia is a low-power Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 4.7 V nominal working voltage with ±2 % tolerance, 500 mW total power dissipation, and 425 Ω typical differential resistance at IZ = 5 mA. It serves as a precision reference or shunt regulator in low-current analog signal conditioning and power rail stabilization circuits.
For engineers reviewing the BZV55-B4V7,115 datasheet, BZV55-B4V7,115 pinout, BZV55-B4V7,115 application, or BZV55-B4V7,115 equivalent, key selection criteria include its tight 4.7 V regulation tolerance, low 3 µA reverse leakage at VR = 2 V, −1.4 mV/K temperature coefficient, 300 pF capacitance at 1 MHz, and SOD80C thermal resistance of 300 K/W to solder point.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable DC voltage across its terminals under varying load or input conditions. Its regulation accuracy relies on tightly controlled silicon process parameters enabling ±2 % nominal voltage tolerance and predictable temperature drift behavior.
The device exhibits low dynamic impedance (425 Ω typ. at 5 mA) and minimal capacitive loading (300 pF at 0 V), making it suitable for noise-sensitive references and fast transient response in feedback networks. Thermal performance is defined with Rth(j-sp) = 300 K/W when mounted on a standard ceramic substrate.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 4.7 V ±2 % - precise shunt regulation point for 5 V rail referencing or biasing |
| Differential Resistance | 425 Ω typ. at IZ = 5 mA - low dynamic impedance ensures stable regulation under small load variations |
| Reverse Leakage Current | 3 µA max. at VR = 2 V - minimal parasitic current preserves accuracy in high-impedance reference nodes |
| Temperature Coefficient | −1.4 mV/K - predictable negative drift enables compensation in temperature-critical references |
| Total Power Dissipation | 500 mW at Tamb ≤ 50 °C - supports continuous operation in compact SMD layouts without forced cooling |
| Package Thermal Resistance | Rth(j-sp) = 300 K/W - defines junction-to-solder-point thermal path for PCB-level thermal design |
| Diode Capacitance | 300 pF at f = 1 MHz, VR = 0 V - low capacitance avoids signal coupling or phase shift in AC-coupled feedback paths |
Pinout & Package

Applications
| Power Supply Reference | Signal Level Shifting |
|---|---|
Use Scenario: Providing stable 4.7 V reference for ADC voltage reference inputs or LDO feedback dividers. IC Role / Device Role / Timing Role: Shunt voltage reference establishing accurate scaling for analog-to-digital conversion. Use Value: ±2 % tolerance and −1.4 mV/K TC ensure <10 mV total drift over −40 °C to +85 °C ambient range. |
Use Scenario: Clamping or shifting logic-level signals between mixed-voltage domains (e.g., 3.3 V MCU to 5 V peripheral). IC Role / Device Role / Timing Role: Passive level translator using Zener forward drop and reverse breakdown thresholds. Use Value: Low 0.9 V forward voltage and sharp 4.7 V knee enable clean threshold detection without active circuitry. |
| Overvoltage Protection | Analog Sensor Biasing |
Use Scenario: Protecting sensitive analog front-end inputs from ESD or supply transients. IC Role / Device Role / Timing Role: Clamp diode limiting input voltage to 4.7 V + VF during fault conditions. Use Value: 40 W non-repetitive peak power rating absorbs 100 µs surges without degradation. |
Use Scenario: Biasing bridge sensors or RTDs requiring stable excitation voltage. IC Role / Device Role / Timing Role: Precision current source element via series resistor + Zener voltage reference. Use Value: 425 Ω differential resistance ensures <0.5 % regulation error across 1–10 mA bias current range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C4V7 | ±5 % tolerance, higher 500 Ω rdif, same SOD80C package | Acceptable where cost sensitivity outweighs precision requirements | Select for non-critical biasing where ±5 % voltage variation is permissible |
| MMSZ4704T1G | ±5 % tolerance, 500 mW rating, SOD-123 package (larger footprint) | Requires PCB layout change; higher thermal resistance (400 K/W) | Choose only if SOD-123 is standardized in existing production lines |
Compared with BZV55-B4V7,115, BZX55C4V7 trades regulation accuracy for cost, while MMSZ4704T1G sacrifices board space efficiency and thermal performance for broader distributor availability-neither offers the same combination of ±2 % tolerance, SOD80C compactness, and 300 K/W thermal path.

FAQ
What is the maximum continuous reverse current for BZV55-B4V7,115?
The device has no specified maximum continuous reverse current; instead, it is limited by total power dissipation of 500 mW at Tamb ≤ 50 °C. At 4.7 V, this corresponds to ~106 mA maximum steady-state Zener current. Exceeding this risks thermal runaway due to junction temperature rise beyond 200 °C absolute maximum.
Does BZV55-B4V7,115 support reflow soldering?
Yes, BZV55-B4V7,115 is qualified for lead-free reflow soldering per JEDEC J-STD-020. The recommended profile uses peak temperature ≤ 260 °C for ≤ 30 seconds, with preheat ramp rate ≤ 3 °C/s. Figure 7 in the datasheet provides the exact SOD80C land pattern dimensions required for reliable joint formation.
How does the temperature coefficient affect regulation accuracy over temperature?
With a typical SZ of −1.4 mV/K, the Zener voltage decreases by ~112 mV over an 80 K rise (−40 °C to +85 °C). Combined with ±2 % initial tolerance (±94 mV), total worst-case deviation is ±206 mV - acceptable for most non-precision references but insufficient for metrology-grade applications without external compensation.
Can BZV55-B4V7,115 be used in place of a 5.1 V Zener diode?
No - BZV55-B4V7,115 is specifically characterized for 4.7 V nominal regulation and exhibits distinct electrical behavior (e.g., −1.4 mV/K TC vs. −0.8 mV/K for BZV55-B5V1). Substituting it for a 5.1 V part introduces ~8.5 % voltage error and alters thermal drift response, potentially destabilizing feedback loops or violating system voltage margins.
