Product details
Overview
BZV55-C16,115 from Nexperia is a 16 V ±5 % tolerance silicon Zener diode in a hermetically sealed SOD80C glass SMD package, rated for 500 mW total power dissipation and 40 W non-repetitive peak reverse power (tp = 100 µs), used for precision low-power voltage regulation and reference functions in analog signal conditioning circuits.
For engineers reviewing the BZV55-C16,115 datasheet, BZV55-C16,115 pinout, BZV55-C16,115 application, or BZV55-C16,115 equivalent, this page delivers verified electrical parameters, thermal behavior, cathode/anode terminal mapping, real-world use cases in voltage reference and overvoltage protection, and validated alternative parts with documented tolerance and dynamic resistance differences.
Technical Context
This Zener diode operates in reverse breakdown with a nominal Zener voltage of 16 V at IZ = 5 mA, exhibiting a typical differential resistance of 50 Ω and a temperature coefficient of +10.4 mV/K. Its low capacitance (75 pF at f = 1 MHz, VR = 0 V) supports stable DC reference performance without high-frequency coupling.
The device features a maximum forward voltage of 0.9 V at IF = 10 mA and a reverse leakage current ≤50 nA at VR = 11.2 V (0.7 × VZ(nom)). 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) | 15.3 V to 17.1 V at IZ = 5 mA - defines regulated output range under nominal bias |
| Differential Resistance (rdif) | 50 Ω typical at IZ = 5 mA - determines load regulation error sensitivity to current variation |
| Temperature Coefficient (SZ) | +10.4 mV/K typical - quantifies VZ drift per degree Celsius rise in junction temperature |
| Total Power Dissipation (Ptot) | 500 mW max on ceramic substrate - sets absolute thermal limit for continuous DC operation |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 µs - enables transient overvoltage clamping without failure |
| Reverse Leakage (IR) | ≤50 nA at VR = 11.2 V - ensures minimal current draw in standby regulation mode |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - confirms low-loss conduction when forward-biased as rectifier |
Pinout & Package
Hermetically sealed glass SOD80C surface-mount package: 3.3–3.7 mm length, 1.45–1.60 mm width, 0.3 mm height; marking band denotes cathode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; reverse-biased during Zener operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZV55-B16,115 | ±2 % tolerance (15.7–16.3 V), 50 Ω rdif, +10.4 mV/K SZ | Higher precision reference needed for closed-loop feedback with <0.5 % error budget | Select when tighter VZ tolerance is required and cost premium is acceptable |
| MMBZ5245BS-7-F | 16 V ±5 %, 150 Ω rdif, SOD-323 package, 350 mW Ptot | Lower power handling and higher dynamic impedance reduce regulation accuracy under varying loads | Choose only for space-constrained layouts where SOD-323 footprint is mandatory |
Compared with BZV55-C16,115, the BZV55-B16,115 offers tighter voltage control at identical thermal and surge performance, while MMBZ5245BS-7-F trades regulation stability and power margin for smaller size-making it unsuitable for sustained 5 mA bias or transient-heavy environments.

FAQ
What is the maximum continuous Zener current for BZV55-C16,115 at 25 °C?
The device supports up to 31.25 mA continuous Zener current at 25 °C, calculated from its 500 mW total power dissipation rating divided by nominal 16 V Zener voltage. Derating is required above 50 °C ambient per the 400 mW limit at Tamb ≤50 °C.
Can BZV55-C16,115 be used in place of a 15 V Zener diode?
No-BZV55-C16,115 has a guaranteed minimum Zener voltage of 15.3 V and maximum of 17.1 V at 5 mA, making it unsuitable as a direct replacement for a true 15 V part. Substituting would cause systematic 0.7–2.1 V positive offset in reference or clamping thresholds.
How does the SOD80C package affect thermal performance compared to DO-35?
The SOD80C's 380 K/W junction-to-ambient thermal resistance in free air is significantly higher than DO-35's ~200 K/W, meaning it dissipates less power continuously without heatsinking. However, its hermetic glass construction provides superior long-term parameter stability versus epoxy-packaged DO-35 variants.
Is BZV55-C16,115 suitable for automotive applications?
No-this part is not AEC-Q200 qualified and lacks automotive-grade screening, temperature validation, or failure mode documentation. Nexperia explicitly states non-automotive qualified products are unsuitable for safety-critical or life-support systems, including automotive ECUs and ADAS sensors.
