Product details
Overview
BZV55-B5V1,115 from Nexperia is a low-power Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, designed for precision voltage reference and regulation in low-current analog circuits. It delivers a nominal 5.1 V Zener voltage with ±2 % tolerance (B-series), 400 Ω typical differential resistance at IZ = 5 mA, <2 µA reverse leakage at VR = 2 V, and 500 mW total power dissipation - enabling stable biasing in sensor interfaces and power supply feedback paths.
For engineers reviewing the BZV55-B5V1,115 datasheet, BZV55-B5V1,115 pinout, BZV55-B5V1,115 application, or BZV55-B5V1,115 equivalent, this page provides verified package mapping, validated thermal and electrical specs, confirmed SOD80C footprint compatibility, and real-world use cases for low-power voltage referencing in industrial and consumer electronics.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable reference voltage across its cathode–anode terminals under controlled current conditions. Its low differential resistance (400 Ω typ. at 5 mA) ensures minimal voltage variation with load changes, while its negative temperature coefficient (−2.7 to −0.8 mV/K) enables predictable thermal drift compensation in multi-device references.
The device is rated for non-repetitive peak reverse power dissipation of 40 W (100 µs square wave, Tj = 25 °C), and its junction-to-ambient thermal resistance is 380 K/W in free air - confirming suitability for low-duty-cycle transient suppression and steady-state regulation without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.0 V to 5.2 V at IZ = 5 mA - defines precise regulation point for feedback loops and reference generation |
| Differential Resistance (rdif) | 400 Ω typical at IZ = 5 mA - determines output impedance and load regulation error |
| Reverse Leakage Current (IR) | <2 µA at VR = 2 V - ensures minimal quiescent current draw in battery-powered circuits |
| Total Power Dissipation (Ptot) | 500 mW maximum at Tamb ≤ 50 °C - sets upper limit for continuous DC power handling |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - confirms low-loss forward conduction for polarity protection or clamping |
| Thermal Resistance (Rth(j-a)) | 380 K/W in free air - quantifies self-heating under ambient conditions without heatsinking |
| Package | SOD80C - hermetically sealed glass SMD outline (3.3–3.7 mm length, 1.45–1.60 mm width, 0.3 mm height) with defined reflow footprint |
Pinout & Package
Hermetically sealed glass SOD80C package: 3.7 mm × 1.6 mm × 0.3 mm body with axial leads trimmed for surface mounting; cathode indicated by black band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; reverse-biased terminal where Zener breakdown occurs |
| 2 | Anode | Connected to ground or lower-potential rail; completes reverse-bias path for regulation current |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance (B-series) | Enables high-accuracy voltage references without post-calibration in cost-sensitive designs |
| Low differential resistance (400 Ω typ.) | Minimizes output voltage shift under varying load currents - critical for stable ADC reference rails |
| Hermetically sealed glass SMD package | Ensures long-term reliability and moisture resistance in harsh environments without conformal coating |
| Non-repetitive peak power rating (40 W) | Supports transient overvoltage clamping in low-energy surge events without degradation |
| Wide operating temperature range (−65 °C to +200 °C) | Validates use in extended-temperature industrial and automotive under-hood applications |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C5V1,113 | ±5 % tolerance (C-series), higher 600 Ω typical rdif, same SOD80C package | Acceptable where cost priority outweighs accuracy; less stable under varying load | Select only if system-level calibration compensates for wider VZ spread and higher impedance |
| MMSZ5231B-7-F | Same ±2 % tolerance, but SOD-123 package (larger footprint), 150 Ω rdif, 350 mW Ptot | Higher power density not needed; requires PCB layout change due to different land pattern | Prefer only when existing design uses SOD-123 and thermal margin allows reduced power rating |
Compared with BZV55-B5V1,115, the BZX55C5V1,113 trades accuracy for cost and the MMSZ5231B-7-F trades package compatibility for lower impedance - making the BZV55-B5V1,115 optimal for new designs requiring tight-tolerance, low-leakage, SOD80C-compatible Zener regulation.

FAQ
What is the maximum continuous Zener current for reliable operation?
The BZV55-B5V1,115 supports up to 100 mA DC Zener current under ambient conditions ≤50 °C, derived from its 500 mW total power dissipation rating and 5.1 V nominal voltage. At higher ambient temperatures, derating applies per the thermal resistance curve - e.g., at 70 °C ambient, max IZ drops to ~75 mA to maintain safe junction temperature.
Can this diode be used in series for higher reference voltages?
Yes - multiple BZV55-B5V1,115 diodes can be stacked anode-to-cathode to achieve higher composite reference voltages (e.g., two in series yield ~10.2 V). However, temperature coefficients accumulate linearly, and mismatched units may cause uneven voltage division; matched lots are recommended for precision applications.
Is the SOD80C package compatible with standard reflow profiles?
Yes - the SOD80C package is qualified for lead-free reflow soldering per JEDEC J-STD-020. The recommended profile includes peak temperature ≤260 °C for ≤10 seconds, with ramp rates ≤3 °C/s, matching IPC-A-610 Class 2/3 requirements and verified in Nexperia's Application Note AN10350.
How does the −2.7 to −0.8 mV/K temperature coefficient affect circuit performance?
This negative coefficient means VZ decreases by 0.8–2.7 mV per °C rise in junction temperature. In a 5.1 V reference, that translates to −0.016 %/°C to −0.053 %/°C drift - acceptable for non-precision applications, but requires compensation (e.g., with positive-TC resistors) in high-stability systems like data acquisition front-ends.
