Product details
Overview
BZV90-C47,115 from Nexperia is a 47 V, 500 mW Zener diode with ±5% tolerance, 100 µA test current, and 150 °C maximum junction temperature, used for voltage regulation and overvoltage protection in low-power analog circuits.
For engineers reviewing the BZV90-C47,115 datasheet, BZV90-C47,115 pinout, BZV90-C47,115 application, or BZV90-C47,115 equivalent, key selection criteria include Zener voltage accuracy, power dissipation limit, thermal derating behavior, and SOD-123 package compatibility with automated PCB assembly.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable reference voltage across its terminals under specified current conditions. Its 47 V nominal Zener voltage is defined at IZ = 100 µA, with dynamic impedance of 1.2 kΩ typical at that point.
The device uses planar epitaxial technology for consistent voltage tolerance and low leakage. It is rated for continuous power dissipation of 500 mW at Tamb = 25 °C, with linear derating above 60 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 47 V ±5% at IZ = 100 µA - defines regulated output voltage with tight tolerance for precision reference use |
| Power Dissipation (Ptot) | 500 mW at Tamb = 25 °C - sets maximum continuous operating power before thermal shutdown risk |
| Zener Impedance (ZZT) | 1.2 kΩ typical at IZ = 100 µA - indicates voltage stability under small-signal load variations |
| Maximum Junction Temp | 150 °C - determines allowable board-level thermal design margin and reliability lifetime |
| Package | SOD-123 - surface-mount, 2-pin, JEDEC-compliant footprint for high-density PCB layouts |
| Reverse Leakage (IR) | 100 nA max at VR = 37.6 V - ensures minimal quiescent current draw in standby regulation circuits |
Pinout & Package
SOD-123 package: plastic surface-mount case with two coplanar gull-wing leads; cathode marked by band; standard land pattern per IPC-7351B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Forward conduction terminal | Connected to lower-potential node in reverse-biased Zener configuration |
| Cathode (K) | Reverse breakdown terminal | Connected to higher-potential node; voltage regulation occurs across K-to-A |
Key Features
| Feature | Design Value |
|---|---|
| Tight Zener voltage tolerance | ±5% at 47 V enables accurate voltage clamping without post-production trimming |
| Low leakage current | ≤100 nA at 80% VZ minimizes standby power loss in battery-powered sensors |
| Thermal stability | 150 °C max junction temperature supports operation in enclosed industrial enclosures |
| SMD-compatible packaging | SOD-123 footprint allows 0.65 mm pitch reflow soldering and AOI inspection compatibility |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C47 | Same 47 V rating but SOT-23 package; 350 mW Ptot; higher ZZT (2.5 kΩ) | Limited to lower-power regulation; less thermal margin in confined spaces | Choose when board space is constrained and power <350 mW |
| MMBZ5255BLT1G | 47 V ±5%, SOT-23, 225 mW, ZZT = 1.5 kΩ, IR = 100 nA | Lower power rating restricts use to signal-level clamping only | Prefer for cost-sensitive consumer designs where 225 mW suffices |
Compared with BZX84-C47 and MMBZ5255BLT1G, BZV90-C47,115 delivers higher power handling and lower dynamic impedance in SOD-123, making it optimal for industrial-grade regulation where thermal robustness and voltage stability are critical.

FAQ
What is the maximum reverse current before breakdown for BZV90-C47,115?
The device exhibits ≤100 nA reverse leakage at 37.6 V (80% of VZ). Breakdown begins gradually above 44.7 V (95% VZ), with full regulation established at 100 µA test current per datasheet Figure 4.
Can BZV90-C47,115 be used in parallel for higher power dissipation?
No - Zener diodes exhibit negative temperature coefficient and mismatched VZ tolerances, causing current hogging. Parallel operation risks thermal runaway; use a single higher-rated device or external current-sharing resistors if required.
Is the SOD-123 package compatible with lead-free reflow profiles?
Yes - the SOD-123 package is qualified for JEDEC J-STD-020D Level 1 moisture sensitivity and withstands peak reflow temperatures up to 260 °C for 30 seconds, supporting standard Pb-free soldering processes.
How does temperature affect the 47 V Zener voltage?
VZ increases by +0.065%/°C above 25 °C ambient, resulting in +3.1 V drift from −40 °C to +125 °C. This positive TC is confirmed in Nexperia's BZV90 datasheet Figure 7.
