Product details
Overview
BZV55-B3V9,115 from Nexperia is a low-power Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 3.9 V nominal regulation at 5 mA with ±2 % tolerance, 400 Ω typical differential resistance, and −2.5 mV/K temperature coefficient. It delivers stable reference voltage in low-current bias networks, power supply feedback paths, and overvoltage protection circuits for consumer and industrial electronics.
For engineers reviewing the BZV55-B3V9,115 datasheet, BZV55-B3V9,115 pinout, BZV55-B3V9,115 application, or BZV55-B3V9,115 equivalent, this page provides verified electrical parameters, thermal behavior under transient surge, reverse leakage at 1 V (≤3 µA), forward voltage at 10 mA (≤0.9 V), and SOD80C footprint compatibility for PCB layout validation.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable DC reference voltage across its terminals under varying load and temperature conditions. Its low 400 mW total power dissipation and 380 K/W junction-to-ambient thermal resistance require careful thermal management on FR4 or ceramic substrates.
The device exhibits a negative temperature coefficient of −2.5 mV/K at IZ = 5 mA, enabling predictable drift compensation in precision references. Its 3 µA maximum reverse leakage at VR = 1 V ensures minimal quiescent current draw in battery-powered sensing nodes.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52-B3V9,215 | Same 3.9 V/±2 % spec but in SOD123 package; higher 500 mW Ptot; 250 Ω rdif | Higher power handling suits higher-current bias networks; larger footprint requires layout change | Select when >400 mW continuous dissipation or lower dynamic impedance is required |
| MMSZ5227B-7-F | 3.9 V/±5 % in SOD-123; 500 mW Ptot; 10 µA IR at 1 V; 90 Ω rdif | Looser tolerance and higher leakage reduce precision; lower rdif improves regulation | Choose for cost-sensitive designs where ±5 % regulation and higher leakage are acceptable |
Compared with BZV55-B3V9,115, the BZT52-B3V9,215 offers better thermal performance and lower impedance but requires SOD123 layout adaptation, while MMSZ5227B-7-F trades precision and leakage for lower impedance and broader availability - making each suitable for distinct trade-off priorities in reference, clamp, or bias roles.

FAQ
What is the maximum continuous reverse current for BZV55-B3V9,115 at 3.9 V?
The device is rated for 5 mA nominal Zener test current, with absolute maximum forward current of 250 mA. Continuous reverse current must be limited by external series resistance to maintain junction temperature below 150 °C and power dissipation within 400 mW at Tamb ≤ 50 °C. Derating applies above 50 °C ambient.
Can BZV55-B3V9,115 be used in place of a 3.3 V Zener diode?
No - BZV55-B3V9,115 is specified for 3.9 V nominal regulation with ±2 % tolerance (3.82–3.98 V range). Substituting it for a 3.3 V part would result in ~18 % higher reference voltage, causing incorrect feedback, overvoltage clamping, or threshold detection. Use BZV55-B3V3,115 for 3.3 V applications.
Is the SOD80C package compatible with standard reflow soldering profiles?
Yes - Nexperia specifies compatibility with JEDEC J-STD-020D reflow profiles. The SOD80C footprint requires a 2.30 × 4.30 mm solder land pattern (per Figure 7), with peak temperature ≤260 °C and time above liquidus 60–150 seconds. Thermal resistance from junction to solder point is 300 K/W, confirming robust thermal transfer during reflow.
How does temperature affect the Zener voltage of BZV55-B3V9,115?
It exhibits a negative temperature coefficient of −2.5 mV/K at IZ = 5 mA, meaning its regulated voltage decreases by approximately 2.5 mV per Kelvin rise in junction temperature. Over −40 °C to +125 °C, this results in a total drift of ~−415 mV, which must be accounted for in precision reference designs using temperature compensation techniques.
