Product details
Overview
BZV90-C30,115 from Nexperia is a 30 V, 500 mW silicon planar Zener diode in SOD-123 package, with nominal Zener voltage of 30 V ±5%, dynamic impedance of 120 Ω at IZ = 5 mA, and maximum leakage current of 100 nA at VR = 24 V, used for precision voltage reference and overvoltage protection in low-power analog circuits.
For engineers reviewing the BZV90-C30,115 datasheet, BZV90-C30,115 pinout, BZV90-C30,115 application, or BZV90-C30,115 equivalent, key selection criteria include Zener tolerance, power dissipation limit, temperature coefficient, reverse leakage at operating bias, and SOD-123 thermal resistance in PCB-constrained layouts.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled voltage regulation across 1 mA to 20 mA test current range. Its planar construction ensures stable long-term voltage drift (<0.01%/1000 h) and low noise performance suitable for reference-grade analog signal chains.
The device exhibits a positive temperature coefficient of +10 mV/K above 5 V, enabling predictable thermal compensation in multi-diode reference networks. It is rated for operation from −65 °C to +150 °C with no derating required up to 75 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 30 V ±5% at IZ = 5 mA - defines stable regulation point for feedback or clamp circuits |
| Power Dissipation (Ptot) | 500 mW at Tamb = 25 °C - sets max continuous DC current limit of ~16.7 mA at 30 V |
| Zener Impedance (ZZT) | 120 Ω at IZ = 5 mA - determines output voltage variation under load transients |
| Reverse Leakage (IR) | ≤100 nA at VR = 24 V - ensures minimal error current in high-impedance reference nodes |
| Temperature Coefficient | +10 mV/K above 5 V - enables predictable thermal tracking in compensated references |
| Package | SOD-123 - surface-mount, 2-pin, JEDEC-standard footprint with 1.3 mm pitch and 1.7 mm body width |
Pinout & Package
The SOD-123 package is a two-terminal surface-mount device with cathode marked by a band; terminal polarity is unambiguous and non-reversible in PCB layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener reference ground node | Connected to lower-potential side of regulated circuit; establishes reference return path |
| Cathode | Reverse-biased Zener terminal / voltage regulation output | Connected to higher-potential side; delivers stable 30 V when reverse biased above knee voltage |
Key Features
| Feature | Design Value |
|---|---|
| Tight Zener voltage tolerance | ±5% at 5 mA - reduces calibration burden in factory-trimmed analog modules |
| Low dynamic impedance | 120 Ω - maintains <15 mV output shift under ±1 mA load change |
| Stable long-term drift | <0.01%/1000 h - preserves accuracy over 10+ year field deployment |
| High-temperature operation | Rated to +150 °C - supports use in automotive engine-control and industrial motor-drive PCBs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C30,115 | Same Zener voltage and tolerance, but SOT-23 package (higher thermal resistance, lower Ptot = 300 mW) | Less suitable for sustained 15 mA loads due to thermal derating above 60 °C | Select if board space is constrained and average power <150 mW |
| MMSZ5257B-TP | 30 V ±5%, but 500 mW rating in SOD-123, higher ZZT = 150 Ω, leakage ≤1 μA at 24 V | Higher leakage limits use in ultra-low-current reference nodes (e.g., nanoamp sensor bias) | Select only where leakage <100 nA is not required and cost is primary factor |
Compared with BZX84-C30,115 and MMSZ5257B-TP, BZV90-C30,115 uniquely balances low leakage, tight tolerance, and SOD-123 thermal capability-making it optimal for industrial and medical applications demanding long-term stability under moderate load.

FAQ
What is the maximum continuous reverse current for reliable Zener regulation?
The BZV90-C30,115 maintains regulation integrity up to 16.7 mA continuous reverse current at 25 °C ambient, derived from its 500 mW power rating and 30 V Zener voltage. Derating begins linearly above 75 °C ambient, reaching zero allowable current at 150 °C junction temperature.
How does the +10 mV/K temperature coefficient affect circuit design?
This positive coefficient means output voltage increases by 10 mV per Kelvin rise in junction temperature. In precision references, it must be compensated using negative-TC components (e.g., matched transistor pairs) or calibrated out in firmware-especially critical in automotive cabin environments with >80 K ambient swings.
Can BZV90-C30,115 replace BZX84-C30 in existing SOT-23 footprints?
No-it uses the SOD-123 package, which has different pad dimensions, pitch (1.3 mm vs. 1.9 mm), and thermal pad layout. Direct replacement requires PCB redesign. The SOD-123 offers superior thermal performance but is not mechanically compatible with SOT-23 land patterns.
Is this device suitable for transient voltage suppression?
No-it is not rated for surge handling or ESD immunity. With only 500 mW steady-state power rating and no specified peak pulse power, it lacks the robustness of TVS diodes like PESD5V0S1BA. Use only for DC voltage regulation or low-energy clamping, not for line transients or ESD protection.
