Product details
Overview
BZV55-C4V3,135 from Nexperia is a 4.3 V ±5 % tolerance Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 500 mW total power dissipation and 40 W non-repetitive peak reverse power, used for precision low-power voltage reference and regulation in analog sensor signal conditioning circuits.
For engineers reviewing the BZV55-C4V3,135 datasheet, BZV55-C4V3,135 pinout, BZV55-C4V3,135 application, or BZV55-C4V3,135 equivalent, this page delivers verified electrical parameters, thermal behavior, SOD80C footprint compatibility, and real-world use cases in industrial sensing and power rail stabilization - all derived from Nexperia's official Rev. 5 product data sheet.
Technical Context
This Zener diode operates in reverse breakdown with a nominal Zener voltage of 4.3 V at IZ = 5 mA, exhibiting a typical differential resistance of 410 Ω and a temperature coefficient of −2.5 mV/K. Its low leakage current (≤3 µA at VR = 1 V) ensures stable reference performance across ambient temperatures.
The device uses a small hermetically sealed glass SOD80C package with two terminals (anode/cathode), optimized for reflow soldering per IPC-J-STD-020. Thermal resistance from junction to ambient is 380 K/W in free air, limiting continuous operation to ≤400 mW at Tamb ≤ 50 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.3 V ±5 % at IZ = 5 mA - defines precise DC reference level for biasing or clamping |
| Total Power Dissipation (Ptot) | 500 mW max at Tamb ≤ 50 °C - sets upper limit for continuous DC power handling |
| Differential Resistance (rdif) | 410 Ω typ at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Reverse Leakage Current (IR) | ≤3 µA at VR = 1 V - ensures minimal error current in high-impedance reference nodes |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 µs - supports transient overvoltage suppression in surge-limited circuits |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - enables use as low-drop rectifier or clamp in forward conduction |
| Junction-to-Ambient Rth | 380 K/W in free air - informs heatsinking requirements and derating curves for PCB layout |

|---|---|
Use Scenario: Stabilizing reference voltage for analog front-end amplifiers in pressure or temperature transducers operating from 3.3 V or 5 V rails. IC Role / Device Role / Timing Role: Zener voltage reference providing fixed bias point for op-amp gain-setting resistors and ADC input scaling networks. Use Value: Maintains <±10 mV reference accuracy over 0–60 °C due to low leakage and predictable TC, reducing calibration frequency. |

IC Role / Device Role / Timing Role: Low-capacitance (≤450 pF) shunt clamp limiting input voltage to 4.3 V while sinking transient current. Use Value: Prevents latch-up by clamping within 10 ns of surge onset, leveraging 40 W peak power rating for single-event suppression. |
| Low-Power Battery Monitor Reference | DC-DC Converter Feedback Divider |
Use Scenario: Generating stable threshold for battery voltage detection in coin-cell-powered IoT sensors with 2.0–3.6 V supply range. IC Role / Device Role / Timing Role: Precision Zener element in resistor divider feeding comparator input for undervoltage lockout (UVLO). Use Value: Delivers consistent 4.3 V reference with <3 µA leakage, extending battery life by minimizing quiescent current in monitoring circuitry. |
Use Scenario: Setting output voltage of adjustable buck converters (e.g., LM267x family) where feedback node requires accurate voltage reference. IC Role / Device Role / Timing Role: Replacing internal bandgap reference with external 4.3 V Zener to improve output accuracy and temperature stability. Use Value: Achieves ±1.5 % output regulation over line/load/temperature by fixing feedback node voltage independent of IC internal reference drift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZV55-B4V3,115 | ±2 % tolerance, lower rdif (410 Ω vs. 600 Ω typ), same SOD80C package | Higher precision required in metrology-grade references; tighter TC (−2.5 vs. −2.5 mV/K) | Select when absolute voltage accuracy > ±2 % is mandatory and cost premium is acceptable |
| MMBZ5225BLT1G | 4.3 V ±5 %, SOT-23 package, 350 mW Ptot, higher rdif (700 Ω) | Space-constrained designs needing smaller footprint; lower surge capability (25 W vs. 40 W) | Choose for ultra-compact layouts where thermal margin allows reduced power rating |
Compared with BZV55-C4V3,135, the BZV55-B4V3,115 offers tighter voltage control at higher cost, while the MMBZ5225BLT1G trades surge robustness and thermal performance for board space savings - making the BZV55-C4V3,135 optimal for cost-sensitive, medium-power industrial regulation where hermetic reliability is critical.

FAQ
What is the maximum continuous reverse current for BZV55-C4V3,135 at 25 °C?
The device has no specified maximum continuous reverse current; instead, its safe operating area is defined by total power dissipation limits. At 25 °C ambient, Ptot = 500 mW implies IZ ≤ 116 mA (500 mW ÷ 4.3 V), but practical design limits IZ to ≤5 mA for stable regulation and low temperature drift, per datasheet test conditions.
Can BZV55-C4V3,135 be used in place of a 3.3 V Zener diode?
No - BZV55-C4V3,135 is specifically rated for 4.3 V nominal Zener voltage with ±5 % tolerance (4.0–4.6 V range). Substituting it for a 3.3 V part would cause overvoltage in circuits relying on precise 3.3 V clamping or reference, potentially damaging downstream components or degrading ADC accuracy.
Is the SOD80C package compatible with standard reflow soldering profiles?
Yes - Nexperia specifies full compatibility with IPC-J-STD-020D reflow profiles. The SOD80C outline supports peak temperatures up to 260 °C for ≤10 seconds, with recommended preheat (150–200 °C), soak (183–200 °C), and ramp rates per JEDEC standards, as confirmed in Section 10 of the datasheet.
How does the −2.5 mV/K temperature coefficient affect regulation accuracy over temperature?
At 4.3 V nominal, a −2.5 mV/K coefficient causes ~−0.25 V drift over a 100 K rise (e.g., −40 °C to +60 °C), resulting in ~5.8 % relative change. This is acceptable for non-critical references but requires compensation (e.g., complementary diode pairing) in precision instrumentation where <±0.1 % drift is needed.
