Product details
Overview
BZV55-C47,115 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in hermetically sealed glass SOD80C SMD package, rated for 47 V nominal working voltage at 5 mA test current, 500 mW total power dissipation, and 40 W non-repetitive peak reverse power. It delivers low differential resistance (85 Ω typ. at IZ = 2 mA) and operates across −65 °C to +200 °C junction temperature range, commonly used for precision voltage reference and overvoltage protection in low-power analog circuits.
For engineers reviewing the BZV55-C47,115 datasheet, BZV55-C47,115 pinout, BZV55-C47,115 application, or BZV55-C47,115 equivalent, this page provides verified electrical parameters, thermal behavior, SOD80C package layout, real-world use cases in regulation and clamping, and validated alternative parts with documented tolerance and voltage differences.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal 47 V regulation voltage at IZ = 2 mA, exhibiting a temperature coefficient of +50 mV/K and typical differential resistance of 85 Ω. Its low capacitance (40 pF at 1 MHz, 0 V) supports stable performance in high-frequency bias networks.
The device uses a hermetically sealed glass construction for long-term stability and moisture resistance, mounted on ceramic substrate per JEDEC standards. Thermal resistance from junction to ambient is 380 K/W in free air, enabling reliable operation up to 500 mW under controlled PCB layout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Nominal Zener Voltage | 47 V at IZ = 2 mA - defines precise DC reference point for feedback loops and threshold detection |
| Tolerance | ±5 % - allows predictable worst-case voltage deviation in production designs without trimming |
| Differential Resistance | 85 Ω typ. at IZ = 2 mA - determines output impedance and load regulation error in shunt regulator topologies |
| Total Power Dissipation | 500 mW at Tamb ≤ 50 °C - sets maximum continuous DC power handling before thermal derating applies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the maximum continuous reverse current for BZV55-C47,115 at 25 °C?
The device has no specified maximum continuous reverse current; instead, it is limited by total power dissipation of 500 mW. At 47 V, this corresponds to 10.6 mA continuous Zener current. Exceeding this value risks thermal runaway unless heatsinking or derating is applied per the Rth(j-a) = 380 K/W specification.
Can BZV55-C47,115 be used in place of a 47 V Zener with ±2 % tolerance?
No-BZV55-C47,115 has ±5 % tolerance (44–50 V), whereas ±2 % parts like BZV55-B47,115 span 46.1–47.9 V. Substitution may cause out-of-spec regulation in feedback loops requiring tighter voltage windows, especially under temperature variation or aging.
How does the SOD80C package affect soldering process selection?
The SOD80C's glass body and small thermal mass require strict reflow profile adherence: peak temperature ≤260 °C, time above 217 °C ≤60 s, and ramp rate ≤3 °C/s. Wave soldering is not recommended due to thermal shock risk; only reflow with optimized footprint per Nexperia's Figure 7 is validated.
Is BZV55-C47,115 suitable for automotive applications?
No-this part is not AEC-Q200 qualified. Nexperia explicitly states in Section 12.3 that non-automotive qualified products like BZV55-C47,115 are unsuitable for safety-critical or life-support systems, and lack automotive-grade testing for vibration, extended temperature cycling, or humidity resistance.
