Product details
Overview
BZV55-C3V0,115 from Nexperia is a 3.0 V ±5 % tolerance silicon Zener diode in a hermetically sealed SOD80C glass SMD package, rated for 500 mW total power dissipation and 40 W non-repetitive peak reverse power, used for low-power voltage regulation and reference functions in consumer and industrial power supply rails.
For engineers reviewing the BZV55-C3V0,115 datasheet, BZV55-C3V0,115 pinout, BZV55-C3V0,115 application, or BZV55-C3V0,115 equivalent, key selection criteria include nominal Zener voltage (3.0 V), tolerance (±5 %), differential resistance (325–600 Ω at IZ = 5 mA), reverse leakage (≤10 µA at VR = 1 V), and thermal resistance (Rth(j-a) = 380 K/W).
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under varying load and input conditions. Its 3.0 V nominal Zener voltage exhibits a negative temperature coefficient of −3.5 to −2.1 mV/K, enabling predictable drift behavior in temperature-sensitive references.
The device features low differential resistance (325–600 Ω at 5 mA) and low capacitance (≤450 pF at 1 MHz, VR = 0 V), supporting stable regulation in low-noise analog circuits and fast transient response in decoupling applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.8 V to 3.2 V at IZ = 5 mA - defines regulated output voltage range with ±5 % tolerance. |
| Differential Resistance (rdif) | 325–600 Ω at IZ = 5 mA - determines voltage regulation stiffness and load-induced error. |
| Reverse Leakage (IR) | ≤10 µA at VR = 1 V - ensures minimal quiescent current in standby or high-impedance bias networks. |
| Total Power Dissipation (Ptot) | 500 mW at Tamb ≤ 50 °C on ceramic substrate - sets maximum continuous DC power handling capability. |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 µs square wave - supports surge suppression in transient-limited protection circuits. |
| Thermal Resistance (Rth(j-a)) | 380 K/W in free air - governs junction temperature rise under steady-state operation. |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - enables use as low-drop rectifier or clamp in dual-role designs. |
Pinout & Package
Hermetically sealed glass SOD80C surface-mount package (3.3–3.7 mm length × 1.45–1.60 mm width × 0.3 mm height), cathode indicated by marking band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; reverse-biased terminal during Zener operation. |
| 2 | Anode | Connected to ground or lower-potential rail; completes current path during regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass SMD packaging | Ensures long-term reliability and moisture resistance in harsh ambient environments without conformal coating. |
| ±5 % Zener voltage tolerance | Provides cost-optimized regulation accuracy suitable for non-critical reference and clamping applications. |
| Low differential resistance | Minimizes output voltage variation under load changes, improving regulation stability in variable-current circuits. |
| Wide working voltage range (2.4–75 V) | Enables standardized design reuse across multiple supply rails using same package and assembly process. |
| Non-repetitive 40 W surge rating | Allows integration into basic overvoltage protection paths without external TVS devices in low-energy transients. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5222BS-7-F (Diodes Inc.) | Same 3.0 V ±5 % rating, but SOT-23 package (higher Rth(j-a) = 450 K/W); 200 mW Ptot. | Limited to lower-power biasing; unsuitable for 500 mW continuous dissipation scenarios. | Select when board space is constrained and thermal budget allows lower power handling. |
| BZX55C3V0 (ON Semiconductor) | Identical 3.0 V ±5 % spec and SOD-80 package, but higher max IZSM (50 W vs. 40 W) and tighter rdif (250–500 Ω). | Better surge resilience and regulation linearity in high-precision analog references. | Prefer when transient robustness or tighter voltage stability under load variation is required. |
Compared with MMBZ5222BS-7-F, BZV55-C3V0,115 delivers 2.5× higher continuous power and superior thermal performance; versus BZX55C3V0, it trades marginal rdif improvement for broader global availability and identical footprint compatibility.

FAQ
What is the maximum continuous forward current rating for BZV55-C3V0,115?
The absolute maximum forward current is 250 mA per the limiting values table. However, sustained operation above 10 mA is not recommended due to thermal constraints-typical forward voltage is ≤0.9 V at 10 mA, and junction temperature must remain below 200 °C. For reliable long-term use, keep average forward current below 50 mA with adequate PCB copper area.
Can BZV55-C3V0,115 be used as a replacement for a 3.3 V Zener diode?
No-it is specifically rated for 3.0 V nominal Zener voltage with a guaranteed range of 2.8 V to 3.2 V. Substituting it for a 3.3 V part would result in undershoot of the target regulation voltage by ≥0.1 V under typical conditions, potentially causing functional failure in circuits dependent on precise 3.3 V reference or clamping thresholds.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
With a specified temperature coefficient of −3.5 to −2.1 mV/K, the Zener voltage decreases by approximately 21–36 mV across a 60 K temperature span (e.g., 25 °C to 85 °C). At 85 °C, VZ shifts to ~2.96–2.98 V-within the ±5 % band but requiring compensation in high-accuracy references where >0.1 % stability is needed.
Is the SOD80C package compatible with standard reflow soldering profiles?
Yes-the SOD80C outline is qualified for lead-free reflow per JEDEC J-STD-020. Recommended peak temperature is 260 °C for ≤10 seconds, with ramp-up rate ≤3 °C/s. The 1.6 mm width and 3.5 mm length align with common stencil apertures; Figure 7 in the datasheet provides exact land pattern dimensions (2.30 mm × 4.30 mm solder lands).
