Product details
Overview
BZV55-C4V3,115 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 4.3 V nominal Zener voltage at 5 mA, with 410 Ω typical differential resistance and −2.5 mV/K temperature coefficient. It delivers stable reference voltage in low-power analog circuits, power supply feedback loops, and overvoltage protection stages.
For engineers reviewing the BZV55-C4V3,115 datasheet, BZV55-C4V3,115 pinout, BZV55-C4V3,115 application, or BZV55-C4V3,115 equivalent, this page provides verified electrical parameters, thermal behavior, SOD80C footprint details, and validated alternative parts for precision voltage regulation design-in.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 4.3 V reference under regulated current conditions (IZ = 5 mA). Its low 410 Ω differential resistance ensures minimal voltage deviation across load variations, while the negative −2.5 mV/K temperature coefficient enables predictable drift compensation in ambient-variant environments.
Designed for low-power operation, it supports total power dissipation up to 500 mW at Tj ≤ 50 °C and withstands non-repetitive peak reverse power of 40 W (tp = 100 μs), making it suitable for transient suppression and precision biasing where thermal mass is limited.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.0 V to 4.6 V at IZ = 5 mA - defines usable regulation range for 3.3 V/5 V rail monitoring |
| Differential Resistance (rdif) | 410 Ω typ. at IZ = 5 mA - determines output impedance and load regulation error |
| Temperature Coefficient (SZ) | −2.5 mV/K - enables predictable voltage drift correction in temperature-compensated references |
| Forward Voltage (VF) | ≤ 0.9 V at IF = 10 mA - ensures low-loss forward conduction during polarity-reversal protection |
| Reverse Current (IR) | ≤ 3 μA at VR = 1 V - guarantees high off-state impedance for minimal leakage in standby circuits |
| Total Power Dissipation (Ptot) | 500 mW at Tamb ≤ 50 °C - sets maximum continuous DC power handling on standard PCB layout |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 μs - supports short-duration surge clamping without degradation |

|---|---|
Use Scenario: Regulating output voltage in linear regulators or switching converter feedback paths. IC Role / Device Role / Timing Role: Provides precise 4.3 V reference for error amplifier comparison. Use Value: Maintains ±1.5 % output accuracy across 0–70 °C due to stable VZ and low rdif. |
Use Scenario: Clamping transient surges on 3.3 V or 5 V signal lines. IC Role / Device Role / Timing Role: Acts as shunt protector triggered above 4.6 V. Use Value: Absorbs 40 W for 100 μs without failure, limiting downstream voltage to safe levels. |

Use Scenario: Generating stable bias points for op-amp input stages or ADC reference dividers. IC Role / Device Role / Timing Role: Delivers low-drift 4.3 V reference independent of supply ripple. Use Value: −2.5 mV/K coefficient allows predictable compensation when paired with positive-TC components. |
Use Scenario: Translating logic-level signals between 3.3 V and 5 V domains. IC Role / Device Role / Timing Role: Sets clamping threshold to prevent overvoltage on receiver inputs. Use Value: 0.9 V forward drop enables bidirectional level translation with minimal propagation delay. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55-C4V3 | Same 4.3 V nominal, ±5 %, but in larger DO-35 glass package (not SMD); higher Rth(j-a) = 500 K/W | Requires through-hole assembly; less suitable for high-density PCBs | Select when legacy through-hole compatibility or higher surge margin (500 mW Ptot) is prioritized over size |
| MMSZ4V3 | 4.3 V, ±5 %, SOD-123 package; lower rdif = 30 Ω, but max Ptot = 350 mW | Better regulation accuracy, but reduced power handling limits use in >10 mA bias networks | Select when tighter voltage stability is critical and average current remains below 8 mA |
Compared with BZV55-C4V3,115, BZX55-C4V3 trades SMD convenience for higher thermal resistance and through-hole mounting, while MMSZ4V3 improves regulation precision at the expense of 30 % lower power capacity-making the BZV55-C4V3,115 optimal for balanced performance in space-constrained, medium-current regulation.

FAQ
What is the maximum continuous Zener current for BZV55-C4V3,115?
The device supports up to 250 mA forward current, but its Zener regulation region is specified at IZ = 5 mA for VZ measurement. At 500 mW total dissipation and 4.3 V VZ, maximum continuous Zener current is approximately 116 mA - however, derating per thermal resistance (Rth(j-a) = 380 K/W) is required above 50 °C ambient to avoid junction overheating.
How does the −2.5 mV/K temperature coefficient affect circuit performance?
This negative coefficient means VZ decreases by 2.5 mV per Kelvin rise in junction temperature. In a 4.3 V reference, a 50 °C rise causes ~125 mV drop - requiring either ambient stabilization, compensation with positive-TC components, or operation within narrow temperature bands where drift remains within system tolerance.
Can BZV55-C4V3,115 be used in place of a 3.3 V Zener diode?
No - its nominal Zener voltage is 4.3 V (range 4.0–4.6 V), not 3.3 V. Substituting it for a 3.3 V part would raise regulated voltage by >1 V, potentially damaging downstream 3.3 V logic. For 3.3 V regulation, BZV55-C3V3 (3.1–3.5 V) is the correct variant in the same series and package.
What does the "115" suffix indicate in BZV55-C4V3,115?
The "115" denotes the packing method: 115 indicates 2500 units per reel in 4 mm pitch tape-and-reel format, compliant with EIA-481 standards. This distinguishes it from "135", which specifies 10,000 units per reel - both use identical SOD80C packaging and electrical characteristics.
