Product details
Overview
BZV55-C12,115 from Nexperia is a 12 V ±5 % Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 400 mW total power dissipation at Tamb ≤ 50 °C and 500 mW at Ttp ≤ 50 °C, with 11.4–12.7 V nominal Zener voltage, 50–150 Ω differential resistance at IZ = 5 mA, and 100 nA reverse current at VR = 8 V - used for precision low-power voltage reference and overvoltage protection in sensor signal conditioning circuits.
For engineers reviewing the BZV55-C12,115 datasheet, BZV55-C12,115 pinout, BZV55-C12,115 application, or BZV55-C12,115 equivalent, this page delivers verified Zener voltage tolerance, thermal resistance (Rth(j-a) = 380 K/W), non-repetitive peak reverse power (40 W), cathode/anode polarity marking, and SOD80C footprint compatibility for PCB layout validation.
Technical Context
This device operates as a two-terminal shunt voltage regulator, maintaining stable output voltage across load variations by conducting reverse current above its specified Zener breakdown threshold. Its low differential resistance (50–150 Ω) ensures minimal voltage deviation under dynamic load conditions, while its temperature coefficient of +6.0 to +8.4 mV/K at IZ = 5 mA enables predictable drift compensation in bias networks.
The SOD80C package provides hermetic glass sealing for moisture resistance and long-term stability, with defined thermal resistance from junction to ambient (380 K/W) and junction to solder point (300 K/W), supporting reliable operation up to 200 °C storage temperature and 150 °C junction temperature during transient surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 11.4 V min / 12.7 V max at IZ = 5 mA - defines precise regulation window for 12 V rail stabilization |
| Differential Resistance (rdif) | 50 Ω typ / 150 Ω max at IZ = 5 mA - determines output impedance and load regulation error |
| Reverse Current (IR) | 100 nA max at VR = 8 V - ensures negligible leakage in standby or high-impedance bias networks |
| Total Power Dissipation (Ptot) | 400 mW at Tamb ≤ 50 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Non-repetitive Peak Power (PZSM) | 40 W for tp = 100 µs - supports transient surge suppression without failure |
| Thermal Resistance (Rth(j-a)) | 380 K/W in free air - quantifies self-heating impact on voltage drift and reliability margin |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - relevant for reverse-polarity protection or dual-use circuit configurations |
Pinout & Package
Hermetically sealed glass SOD80C package: 3.3–3.7 mm length, 1.45–1.60 mm width, 0.3 mm height; cathode indicated by black band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; reverse-biased terminal where Zener breakdown occurs |
| 2 | Anode | Connected to ground or lower potential reference; completes current path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective selection for non-critical 12 V reference applications without trimming |
| Hermetic glass SMD packaging | Guarantees long-term parameter stability and moisture immunity in industrial environments |
| Low 100 nA reverse leakage at 8 V | Minimizes quiescent current draw in battery-powered sensor front-ends and low-power logic |
| 40 W non-repetitive surge rating | Provides robust ESD and transient overvoltage clamping without external TVS devices |
| 300 K/W junction-to-solder-point Rth | Supports effective heat transfer to copper pour, enabling higher sustained power in compact layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55-C12 (Vishay) | Same 12 V ±5 % rating, but TO-92 through-hole package; 500 mW Ptot at 25 °C only | Requires manual assembly or wave soldering; unsuitable for fully SMT production | Select only if legacy through-hole compatibility or higher ambient derating is required |
| MMSZ5242B (ON Semiconductor) | SOD-123 package; tighter ±5 % tolerance but higher 220 Ω rdif; 500 mW Ptot at 25 °C | Lower thermal resistance (Rth(j-a) ≈ 300 K/W) but reduced regulation stiffness | Prefer for space-constrained boards needing better thermal performance, accepting higher voltage drift |
Compared with BZV55-C12,115, BZX55-C12 trades SMT compatibility for easier prototyping, while MMSZ5242B improves thermal response at the cost of regulation precision - making the BZV55-C12,115 optimal for production-grade SMT designs requiring balanced stability, size, and surge resilience.

FAQ
What is the maximum continuous operating current for BZV55-C12,115?
The device supports up to 250 mA forward current per absolute maximum ratings, but its Zener regulation region is optimized for 1–20 mA reverse current. At 12 V and 400 mW dissipation limit, the practical continuous Zener current is 33 mA - exceeding this risks thermal runaway due to 380 K/W junction-to-ambient resistance.
How does the SOD80C package affect thermal performance compared to SOD-123?
SOD80C exhibits higher thermal resistance (380 K/W vs. ~300 K/W for SOD-123) due to smaller glass body and limited copper contact area, resulting in ~25 °C higher junction temperature at identical power dissipation. This requires stricter ambient temperature control or reduced derating in enclosed assemblies.
Can BZV55-C12,115 be used in place of a 12 V Zener with ±2 % tolerance?
No - BZV55-C12,115 has ±5 % tolerance (11.4–12.7 V), whereas ±2 % variants (e.g., BZV55-B12) specify 11.8–12.2 V. Substituting introduces up to 0.5 V additional regulation uncertainty, which may violate tight reference requirements in precision ADC or DAC bias networks.
Is the cathode marking consistent across all BZV55-Cxx variants?
Yes - all BZV55-Cxx devices use a single black band on the glass body to denote the cathode terminal (Pin 1), aligned with the standardized SOD80C outline drawing and confirmed in Nexperia's pinning documentation for the full series.
