Product details
Overview
BZV55-C30,115 from Nexperia is a ±5 % tolerance silicon Zener diode in a hermetically sealed SOD80C glass SMD package, rated for 30 V nominal Zener voltage at 2 mA test current, 500 mW total power dissipation, and 40 W non-repetitive peak reverse power. It delivers low differential resistance (70 Ω typ. at IZ = 2 mA) and operates across −65 °C to +200 °C junction temperature range, used for precision voltage reference and overvoltage protection in DC power rails.
For engineers reviewing the BZV55-C30,115 datasheet, BZV55-C30,115 pinout, BZV55-C30,115 application, or BZV55-C30,115 equivalent, this page provides verified Zener voltage tolerance, thermal resistance (Rth(j-a) = 380 K/W), reverse leakage (≤50 nA at 21 V), differential resistance, and SOD80C footprint compatibility - all critical for low-power regulation and transient suppression design validation.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified nominal Zener voltage of 30 V at IZ = 2 mA, exhibiting a temperature coefficient of +20.6 mV/K (typ.) and differential resistance of 70 Ω (typ.) at that bias point. Its low capacitance (45 pF at f = 1 MHz, VR = 0 V) supports stable regulation in high-frequency feedback paths.
The device uses a hermetically sealed glass construction for long-term stability and moisture resistance, and its SOD80C package enables surface-mount assembly with defined thermal resistance to ambient (380 K/W) and to solder point (300 K/W) under standard mounting conditions on a 10 × 10 × 0.6 mm ceramic substrate.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 30 V nominal at IZ = 2 mA; ±5 % tolerance ensures predictable clamping in 28.0–32.0 V range for supply rail stabilization. |
| Differential Resistance (rdif) | 70 Ω typical at IZ = 2 mA; low impedance maintains stable output voltage under varying load current. |
| Total Power Dissipation (Ptot) | 500 mW maximum at Tamb ≤ 50 °C; defines continuous safe operating power in compact PCB layouts. |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W for tp = 100 μs square wave; enables transient surge suppression without permanent damage. |
| Reverse Leakage Current (IR) | ≤50 nA at VR = 21 V; minimal standby current preserves battery life in always-on monitoring circuits. |
| Thermal Resistance (Rth(j-a)) | 380 K/W in free air; determines junction temperature rise per watt, critical for reliability in unforced convection environments. |
| Package | SOD80C: hermetically sealed glass SMD outline (3.3–3.7 mm length, 1.45–1.60 mm width, 0.3 mm height); compatible with standard reflow profiles. |
Pinout & Package
SOD80C is a two-terminal surface-mount glass package with axial lead configuration flattened into gull-wing form; cathode identified by a single black band on the glass body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; reverse-biased terminal where Zener breakdown occurs; marking band identifies this pin. |
| 2 | Anode | Connected to circuit ground or lower-potential rail; completes reverse-bias path enabling voltage reference or clamp function. |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-optimized selection for non-critical reference applications without requiring tighter-tolerance (±2 %) B-series parts. |
| Hermetically sealed glass SOD80C package | Provides long-term parameter stability and immunity to humidity-induced drift in industrial and outdoor environments. |
| Low differential resistance (70 Ω typ.) | Minimizes output voltage variation under dynamic load changes, improving regulation accuracy in feedback loops. |
| Wide operating temperature range (−65 °C to +200 °C) | Supports deployment in under-hood automotive modules, industrial motor drives, and high-temperature power supplies. |
| Non-repetitive 40 W surge capability | Allows integration as primary or secondary overvoltage clamp without external TVS, reducing BOM count in DC input stages. |
Applications
| Power Supply Voltage Reference | Overvoltage Protection Clamp |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZV55-B30,115 | ±2 % tolerance (29.4–30.6 V), lower rdif (40 Ω typ.), higher cost | Required where tighter regulation (<±0.3 V) is needed for metrology-grade references | Select when absolute voltage accuracy outweighs cost sensitivity and board space is not constrained. |
| MMBZ5262B,115 | SOT-23 package, 30 V ±5 %, 225 mW Ptot, higher rdif (130 Ω typ.) | Used in ultra-compact consumer electronics where SOD80C footprint is prohibitive | Choose only if PCB area is severely limited and 500 mW power handling is not required. |
Compared with BZV55-C30,115, the BZV55-B30,115 offers superior voltage accuracy but at higher unit cost and identical thermal performance, while the MMBZ5262B,115 sacrifices power rating and regulation stiffness to fit smaller footprints - making the BZV55-C30,115 optimal for cost-sensitive, medium-power industrial regulation where SOD80C layout is acceptable.

FAQ
What is the maximum continuous Zener current for BZV55-C30,115 at 25 °C ambient?
The device supports up to 16.7 mA continuous Zener current at 25 °C ambient, calculated from Ptot = 500 mW and VZ = 30 V (IZ(max) = Ptot/VZ). Derating applies above 50 °C ambient per the thermal resistance specification (Rth(j-a) = 380 K/W).
Can BZV55-C30,115 be used in place of a 30 V TVS diode for ESD protection?
No - it is not rated for repetitive ESD events per IEC 61000-4-2. Its 40 W non-repetitive surge rating applies only to single, short-duration transients (100 μs). For certified ESD protection, use dedicated TVS diodes such as PESD5V0S1BA.
Does the SOD80C package support automated optical inspection (AOI) after reflow?
Yes - the hermetically sealed glass body and distinct cathode band provide high-contrast visual features compatible with standard AOI systems. The flat gull-wing leads and consistent 1.60 mm width enable reliable solder-joint inspection per IPC-A-610 Class 2 requirements.
How does temperature affect the Zener voltage of BZV55-C30,115 in operation?
It exhibits a positive temperature coefficient of +20.6 mV/K (typ.) at IZ = 2 mA, meaning VZ increases ~0.62 V over a 30 K rise (e.g., from 25 °C to 55 °C). This behavior is stable and repeatable, enabling predictable compensation in temperature-aware designs.
