Product details
Overview
BZV55-C3V6,115 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in a hermetically sealed SOD80C glass SMD package, rated for 3.6 V nominal Zener voltage at 5 mA, with 500 mW total power dissipation and 375 Ω typical differential resistance at IZ = 5 mA. It provides stable low-power voltage reference and regulation in space-constrained consumer and industrial power rails.
For engineers reviewing the BZV55-C3V6,115 datasheet, BZV55-C3V6,115 pinout, BZV55-C3V6,115 application, or BZV55-C3V6,115 equivalent, key selection criteria include Zener voltage tolerance (±5 %), thermal resistance (300 K/W to solder point), reverse leakage (≤5 µA at 1 V), SOD80C footprint compatibility, and non-repetitive surge capability (40 W, 100 µs).
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable reference voltage across its cathode–anode terminals under controlled current conditions. Its temperature coefficient of −2.4 mV/K (typical) and low capacitance (≤450 pF at 1 MHz, 0 V) support stable DC biasing and noise-sensitive analog references.
The device is characterized at Tj = 25 °C with defined test currents (IZ = 5 mA for VZ, IZ = 1 mA for rdif) and adheres to IEC 60134 absolute maximum ratings, including 250 mA forward current limit and 200 °C junction temperature ceiling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.4 V to 3.8 V at IZ = 5 mA - defines usable regulation window for 3.3 V system biasing |
| Differential Resistance (rdif) | 375 Ω (typ), 600 Ω (max) at IZ = 5 mA - determines output impedance and load regulation error |
| Reverse Leakage (IR) | ≤5 µA at VR = 1 V - ensures minimal quiescent current in standby or high-impedance sensing nodes |
| Total Power Dissipation (Ptot) | 500 mW at Tamb ≤ 50 °C on ceramic substrate - sets maximum continuous bias current (IZ ≈ 139 mA at 3.6 V) |
| Thermal Resistance (Rth(j-sp)) | 300 K/W junction-to-solder-point - enables thermal design margin for PCB copper area and reflow profile |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 µs square wave - supports transient overvoltage clamping in low-energy protection circuits |
| Package | SOD80C - standardized 3.3 mm × 1.45 mm glass SMD outline with cathode band marking |
Pinout & Package
Hermetically sealed glass SOD80C surface-mount package: 3.3 mm length × 1.45 mm width × 1.60 mm height; cathode indicated by black band; designed for reflow and wave soldering per IPC-J-STD-020/001.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated voltage node; reverse-biased terminal during Zener operation |
| 2 | Anode | Connected to ground or lower-potential rail; completes bias path for Zener current |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-optimized regulation where tight voltage accuracy is not required (e.g., non-critical biasing) |
| Low differential resistance (375 Ω typ) | Minimizes output voltage shift under varying load current in shunt regulator configurations |
| Hermetically sealed glass construction | Ensures long-term stability and moisture resistance without conformal coating in humid environments |
| Small SOD80C footprint | Supports high-density PCB layouts in portable and space-limited applications |
| Non-repetitive 40 W surge rating | Provides transient overvoltage suppression capability without external TVS in low-energy signal paths |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52-C3V6,215 | Same VZ (3.4–3.8 V), but SOD123 package (larger, higher Ptot = 500 mW, Rth(j-a) = 300 K/W vs. 380 K/W) | Preferred for manual assembly or higher thermal mass requirements; less suitable for ultra-dense layouts | Select when board real estate allows larger footprint and higher solder joint reliability is prioritized over miniaturization |
| MMSZ4685T1G | 3.6 V nominal, ±5 %, but SOD123 package and tighter rdif (150 Ω typ); higher IZSM (100 W, 100 µs) | Better regulation stability under dynamic loads; higher surge robustness for noisy industrial environments | Choose when improved load regulation or enhanced transient immunity justifies SOD123 footprint and slightly higher cost |
Compared with BZV55-C3V6,115, the BZT52-C3V6,215 offers identical electrical specs in a more robust mechanical package, while MMSZ4685T1G delivers superior regulation precision and surge handling-both require layout revision due to SOD123 dimensions.

FAQ
What is the maximum continuous Zener current for BZV55-C3V6,115 at 70 °C ambient?
At Tamb = 70 °C, derated power dissipation is 300 mW (per thermal curve interpolation from 400 mW @ 50 °C). With VZ ≈ 3.6 V, maximum continuous IZ is ~83 mA. Operation above this requires thermal analysis of PCB copper area and airflow.
Can BZV55-C3V6,115 be used in place of a 3.3 V LDO for powering ICs?
No-it is a shunt regulator, not a series regulator. It sinks excess current to maintain voltage, requiring a series resistor and generating heat proportional to load variation. It lacks current-limiting or dropout control, making it unsuitable as a primary power source for ICs with variable current draw.
How does the −2.4 mV/K temperature coefficient affect regulation accuracy over −40 to +85 °C?
Over that 125 K range, VZ drift is ~−300 mV (−2.4 mV/K × 125 K), resulting in ~−8.3 % deviation from nominal 3.6 V. For precision references, this necessitates compensation or use only in ambient-stable environments.
Is the SOD80C package compatible with standard reflow profiles for lead-free soldering?
Yes-the device is qualified per J-STD-020, with peak reflow temperature up to 260 °C. The recommended footprint (2.30 mm × 4.30 mm solder lands) and thermal pad design ensure reliable wetting and void-free joints under IPC-A-610 Class 2 conditions.
