Product details
Overview
BZV55-B47,115 from Nexperia is a low-power Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 47 V nominal regulation at 5 mA with ±2 % tolerance, 85 Ω typical differential resistance, and 50 mV/K temperature coefficient. It delivers stable reference voltage in low-current bias networks and power rail clamping circuits for industrial sensor interfaces and microcontroller reset supervision.
For engineers reviewing the BZV55-B47,115 datasheet, BZV55-B47,115 pinout, BZV55-B47,115 application, or BZV55-B47,115 equivalent, this page provides verified electrical parameters, thermal behavior under transient surge, cathode/anode terminal mapping, and validated alternative parts for precision voltage reference design.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 46.1–47.9 V DC reference across its terminals when biased with ≥5 mA current. Its low 85 Ω differential resistance ensures minimal voltage shift under load variation, while the +50 mV/K temperature coefficient enables predictable drift compensation in ambient-temperature-stable circuits.
The device supports non-repetitive 100 µs square-wave surges up to 40 W (IZSM = 0.5 A), and dissipates ≤500 mW total power on a ceramic substrate. Its 40 pF junction capacitance at 0 V and 1 MHz makes it suitable for DC and low-frequency regulation-not RF or high-speed signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 47 V at IZ = 5 mA - defines precise DC reference point for analog sensing or supply monitoring |
| Zener Tolerance | ±2 % - guarantees voltage accuracy within ±0.94 V for calibration-critical applications |
| Differential Resistance | 85 Ω typ. at IZ = 5 mA - limits output voltage change to ≤0.43 V per 5 mA load variation |
| Temperature Coefficient | +50 mV/K - enables predictable +2.35 V drift over 47 °C ambient rise |
| Non-repetitive Peak Power | 40 W for tp = 100 µs - sustains transient overvoltage events without failure |
| Total Power Dissipation | 500 mW at Tj ≤ 50 °C on ceramic substrate - sets maximum continuous bias current to ~10.6 mA |
| Junction Capacitance | 40 pF at VR = 0 V, f = 1 MHz - negligible loading on DC/low-frequency reference nodes |
| Forward Voltage | ≤0.9 V at IF = 10 mA - allows use as polarity-sensitive clamp in bidirectional protection schemes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C47 | ±5 % tolerance, 100 Ω rdif, same SOD80C package | Lower cost; acceptable where ±2.35 V regulation error is permissible | Select when absolute voltage accuracy is secondary to BOM simplification and cost reduction |
| MMSZ47ET1G | ±5 % tolerance, 110 Ω rdif, SOD-123 package (larger footprint) | Higher thermal resistance (400 K/W vs. 300 K/W), lower surge robustness | Choose only if board layout requires SOD-123 compatibility and surge immunity is not required |
Compared with BZV55-B47,115, BZX55C47 trades ±2 % accuracy for broader tolerance and higher rdif, while MMSZ47ET1G sacrifices thermal performance and surge capability for package standardization-making the BZV55-B47,115 optimal for precision, thermally constrained, or transient-prone designs.

FAQ
What is the maximum continuous reverse current for reliable operation?
The BZV55-B47,115 supports up to 10.6 mA continuous reverse current at 50 °C ambient when mounted on a 10 × 10 × 0.6 mm ceramic substrate, based on its 500 mW total power dissipation limit and 47 V Zener voltage. Exceeding this current risks thermal runaway due to positive temperature coefficient behavior above 6 V.
How does the +50 mV/K temperature coefficient affect long-term stability?
The +50 mV/K coefficient means the Zener voltage increases by approximately 2.35 V over a 47 °C ambient rise (e.g., from 25 °C to 72 °C). This drift is linear and repeatable, enabling accurate software-based compensation in closed-loop systems-but requires thermal shielding or calibration if sub-1 % regulation stability is needed across wide temperature ranges.
Can this diode be used in series or parallel configurations?
Series connection is valid for higher-voltage references (e.g., two BZV55-B47,115 yield ~94 V), but mismatched temperature coefficients cause unequal voltage sharing. Parallel use is strongly discouraged-minor VZ differences lead to current hogging and thermal instability, risking premature failure of one device.
Is the SOD80C package compatible with standard reflow profiles?
Yes-the SOD80C package is qualified for JEDEC J-STD-020D reflow, with peak temperatures up to 260 °C for ≤10 seconds. The recommended footprint (2.30 mm × 4.30 mm solder lands) and 4 mm tape pitch ensure compatibility with automated pick-and-place and reflow lines used in high-mix industrial PCB assembly.
