Product details
Overview
BZV55-C15,115 from Nexperia is a ±5 % tolerance silicon Zener diode in a hermetically sealed SOD80C glass SMD package, rated for 15 V nominal Zener voltage at 5 mA, 500 mW total power dissipation, and 75 Ω typical differential resistance. It provides stable voltage regulation in low-power analog reference and overvoltage protection circuits, such as sensor biasing and microcontroller I/O rail clamping.
For engineers reviewing the BZV55-C15,115 datasheet, BZV55-C15,115 pinout, BZV55-C15,115 application, or BZV55-C15,115 equivalent, key selection criteria include Zener voltage tolerance (±5 %), thermal resistance (300 K/W junction-to-solder-point), reverse leakage (≤50 nA at 0.7×VZ), and SOD80C footprint compatibility with standard reflow profiles.
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 +9.2 mV/K at 5 mA and low 75 Ω differential resistance ensure predictable regulation drift and minimal output impedance variation with load.
The device is optimized for DC and low-frequency regulation-not transient suppression-due to its 40 W non-repetitive peak reverse power rating (100 µs square wave) and 380 K/W junction-to-ambient thermal resistance in free air. It requires external current limiting and is not intended for high-speed switching or AC signal clipping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 13.8 V to 15.6 V at IZ = 5 mA - defines usable regulation range for precision biasing |
| Differential Resistance (rdif) | 50 Ω to 200 Ω (typ. 75 Ω at 5 mA) - determines output impedance and load regulation error |
| Temperature Coefficient (SZ) | +9.2 mV/K (typ.) - quantifies VZ drift per °C rise in junction temperature |
| Reverse Leakage (IR) | ≤50 nA at VR = 10.5 V - ensures minimal quiescent current in standby regulation |
| Total Power Dissipation (Ptot) | 500 mW at Tamb ≤ 50 °C on ceramic substrate - sets maximum continuous DC power handling |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 µs pulse - supports brief surge clamping without damage |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - confirms low-loss conduction in forward-biased protection paths |
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 |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective regulation where tight voltage accuracy is not critical (e.g., non-precision supply rails) |
| SOD80C glass SMD package | Provides hermetic sealing for long-term stability and moisture resistance in industrial environments |
| Low 75 Ω differential resistance | Minimizes output voltage shift under varying load currents (e.g., ±1 mA change → ±75 mV shift) |
| 300 K/W junction-to-solder-point thermal resistance | Supports reliable heat transfer to PCB copper when mounted on 10×10 mm ceramic substrate |
| 40 W non-repetitive peak power rating | Allows brief overvoltage event absorption without permanent degradation (e.g., ESD or line transients) |
Applications
| Power Supply Rail Clamping | Sensor Reference Biasing |
|---|---|
Use Scenario: Protecting 3.3 V or 5 V MCU I/O pins from voltage overshoot during hot-plug or ESD events. IC Role / Device Role / Timing Role: Zener clamp placed between I/O line and ground to shunt excess energy above VZ. Use Value: Limits pin voltage to ≤15.6 V while drawing <1 mA at 10.5 V, preventing latch-up or gate oxide damage. |
Use Scenario: Providing stable excitation voltage for resistive temperature detectors (RTDs) in industrial temperature modules. IC Role / Device Role / Timing Role: Low-drift 15 V reference source for constant-current generator driving RTD bridge. Use Value: +9.2 mV/K tempco and 75 Ω rdif yield <0.15 % full-scale error over 0–70 °C ambient range. |
| ADC Input Protection | Low-Power Voltage Reference |
Use Scenario: Preventing overvoltage damage to SAR ADC input pins during signal conditioning stage faults. IC Role / Device Role / Timing Role: Shunt regulator placed after RC filter to clamp fast transients before ADC sampling. Use Value: 50 nA leakage at 10.5 V avoids measurable offset error in high-impedance (>1 MΩ) front-end networks. |
Use Scenario: Generating stable 15 V reference for op-amp-based precision current sources in battery-powered instrumentation. IC Role / Device Role / Timing Role: Primary voltage reference element in two-resistor current mirror configuration. Use Value: 500 mW Ptot allows 33 mA max Zener current, supporting >10 mA output drive with <1 % regulation error. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5245B,115 | Same SOD80C package, ±5 % tolerance, but 15 V nominal at 20 mA; higher test current shifts operating point | Higher IZ rating increases thermal stress in low-current designs; rdif = 17 Ω improves regulation but raises minimum bias requirement | Select when tighter regulation under ≥10 mA load is required and board layout permits identical footprint |
| BZX84-C15,115 | SOT23 package (larger thermal resistance: 450 K/W); same 15 V/±5 % spec but lower Ptot = 300 mW | Reduced power handling limits use in sustained 15 V clamping; less suitable for ceramic-substrate mounting | Choose only if SOT23 is mandated by legacy layout and peak power remains <200 mW |
Compared with BZV55-C15,115, MMBZ5245B,115 delivers superior regulation at higher bias currents but demands more board space for thermal relief, while BZX84-C15,115 sacrifices power margin and thermal performance for SOT23 compatibility-neither offers drop-in equivalence without circuit revalidation.

FAQ
What is the maximum continuous Zener current for BZV55-C15,115 at 25 °C ambient?
The device supports up to 33 mA continuous Zener current at 25 °C ambient when mounted on a 10×10×0.6 mm ceramic substrate, calculated from its 500 mW total power dissipation rating and 15 V nominal Zener voltage. Derating is required above 50 °C ambient per the 300 K/W junction-to-solder-point thermal resistance.
Does BZV55-C15,115 meet automotive AEC-Q200 requirements?
No. BZV55-C15,115 is not automotive-qualified and lacks AEC-Q200 certification. The datasheet explicitly states it is intended for industrial and general-purpose applications only, with no qualification testing performed for temperature cycling, humidity, or vibration per automotive standards.
Can BZV55-C15,115 be used in series for higher voltage regulation?
Yes, but with caution: series connection increases total dynamic impedance and temperature coefficient uncertainty. Each diode's +9.2 mV/K coefficient adds linearly, and mismatched rdif values cause unequal voltage sharing-external balancing resistors are recommended for stable operation above 30 V.
What is the soldering profile compatibility for the SOD80C package?
The SOD80C package is qualified for standard lead-free reflow per JEDEC J-STD-020, with peak temperature ≤260 °C for ≤30 seconds. The recommended footprint uses 2.30 mm × 4.30 mm solder lands with 0.90 mm spacing, matching IPC-7351B density level A for reliable thermal and mechanical attachment.
