Product details
Overview
BZV55-B20,115 from Nexperia is a 20 V ±2 % tolerance Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 500 mW total power dissipation and 40 W non-repetitive peak reverse power, used for precision low-power voltage reference and regulation in analog signal conditioning circuits.
For engineers reviewing the BZV55-B20,115 datasheet, BZV55-B20,115 pinout, BZV55-B20,115 application, or BZV55-B20,115 equivalent, this page delivers verified electrical parameters, thermal behavior, SOD80C footprint details, and validated alternative parts for stable voltage reference design in industrial sensor interfaces and power supply feedback paths.
Technical Context
This Zener diode operates in reverse breakdown with a nominal Zener voltage of 20 V at 5 mA test current, exhibiting a typical differential resistance of 60 Ω and a temperature coefficient of +12.3 mV/K - indicating positive drift with junction temperature rise. Its low 1.5 A non-repetitive peak reverse current supports transient overvoltage clamping in pulse-limited conditions.
Designed for DC voltage reference and shunt regulation, it features low reverse leakage (≤1.5 µA at VR = 14 V), 60 pF diode capacitance at 0 V, and thermal resistance from junction to solder point of 300 K/W when mounted on a 10 × 10 × 0.6 mm ceramic substrate.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 19.6 V to 20.4 V at IZ = 5 mA - defines tight ±2 % regulation window for stable reference generation |
| Differential Resistance (rdif) | 60 Ω (typ) at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Temperature Coefficient (SZ) | +12.3 mV/K (typ) - quantifies voltage drift per degree Celsius rise in junction temperature |
| Total Power Dissipation (Ptot) | 500 mW at Tamb ≤ 50 °C - sets maximum continuous DC power handling under standard mounting |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W for tp = 100 µs square wave - enables short-duration surge suppression without failure |
| Reverse Leakage Current (IR) | ≤1.5 µA at VR = 14 V - ensures minimal error current in high-impedance reference nodes |
| Diode Capacitance (Cd) | 60 pF at f = 1 MHz, VR = 0 V - impacts high-frequency noise rejection and stability in feedback loops |
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 marking 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 rail; completes bias path for reverse conduction |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance | Enables precise DC reference without post-production trimming in cost-sensitive industrial designs |
| Low differential resistance (60 Ω typ) | Minimizes output voltage variation under changing load current in shunt regulator configurations |
| Hermetically sealed glass SMD package | Ensures long-term parameter stability and moisture resistance in harsh ambient environments |
| 40 W non-repetitive peak power rating | Supports transient overvoltage protection in low-energy surge events without derating |
| 300 K/W junction-to-solder-point thermal resistance | Allows direct thermal coupling to PCB copper for effective heat dissipation in compact layouts |
Applications
| Industrial Sensor Signal Conditioning | Microcontroller ADC Reference |
|---|---|
Use Scenario: Providing stable 20 V reference for bridge sensor excitation and instrumentation amplifier gain setting in factory automation transmitters. IC Role / Device Role / Timing Role: Shunt voltage reference establishing fixed bias point for analog front-end circuitry. Use Value: Tight ±2 % tolerance and low 60 Ω dynamic impedance ensure <±0.5 % full-scale error across 0–70 °C operating range. |
Use Scenario: Generating accurate 20 V reference for external 12-bit SAR ADC used in programmable logic controller (PLC) analog input modules. IC Role / Device Role / Timing Role: Precision voltage source feeding ADC reference pin to maximize ENOB and minimize integral nonlinearity. Use Value: Low 1.5 µA reverse leakage prevents loading of high-impedance reference buffer inputs, preserving linearity. |
| Switch-Mode Power Supply Feedback | Overvoltage Clamp in Battery Management |
Use Scenario: Regulating output voltage in isolated flyback converter via optocoupler-coupled feedback loop with TL431 replacement. IC Role / Device Role / Timing Role: Zener element in secondary-side shunt regulator controlling error amplifier bias. Use Value: 20 V breakdown voltage matches common 19–21 V output rails; 40 W surge rating absorbs transformer leakage spikes. |
Use Scenario: Clamping cell voltage during charging in 4S Li-ion battery packs using discrete protection ICs. IC Role / Device Role / Timing Role: Passive overvoltage limiter placed across individual cells to prevent exceeding 20 V absolute max. Use Value: Hermetic glass construction withstands repeated thermal cycling in automotive-grade BMS assemblies without parameter shift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C20,113 | ±5 % tolerance, higher 100 Ω typical rdif, same SOD80C package | Acceptable where ±5 % reference accuracy suffices and cost is prioritized over precision | Select for non-critical biasing where tighter tolerance is unnecessary and BOM simplification is desired |
| MMSZ5248B-TP | ±5 % tolerance, 225 mW Ptot, SOD-123 package, 100 Ω rdif | Limited to lower-power applications due to reduced thermal mass and dissipation capability | Choose only for space-constrained designs with <100 mW average power and no surge requirements |
Compared with BZV55-B20,115, BZX55C20,113 trades ±2 % accuracy and lower dynamic impedance for broader tolerance and lower cost, while MMSZ5248B-TP sacrifices both precision and power handling for smaller footprint - making the BZV55-B20,115 optimal for industrial-grade 20 V references demanding stability, surge resilience, and thermal robustness.

FAQ
What is the maximum continuous forward current for BZV55-B20,115?
The device is not intended for forward conduction; its absolute maximum forward current is 250 mA per limiting values table, but operation in forward bias exceeds design intent. It must be reverse-biased to function as a Zener regulator, with recommended test current of 5 mA for specification compliance.
Can BZV55-B20,115 replace a 20 V TL431-based reference?
No - the BZV55-B20,115 is a two-terminal passive Zener diode requiring external current limiting, whereas TL431 is an active three-terminal adjustable shunt regulator with built-in error amplifier and reference. It can replace fixed-voltage Zener alternatives but not active regulators without circuit redesign.
Is the SOD80C package compatible with standard reflow profiles?
Yes - Nexperia specifies compatibility with JEDEC J-STD-020D reflow profiles. The glass body withstands peak temperatures up to 260 °C for 10 seconds; recommended solder land pattern and paste volume are defined in Figure 7 of the datasheet for reliable void-free joints.
How does temperature affect the 20 V Zener voltage in practical use?
At 5 mA test current, the typical temperature coefficient is +12.3 mV/K, meaning voltage increases ~12.3 mV per °C rise in junction temperature. Over a 0–70 °C ambient range with self-heating, total drift remains within ±0.15 V - acceptable for most industrial reference applications without compensation.
