Product details
Overview
BZV55-B5V1,135 from Nexperia is a low-power Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 5.1 V nominal regulation at 5 mA with ±2 % tolerance, 400 mW total power dissipation (Tamb ≤ 50 °C), and 40 Ω typical differential resistance - used for precision voltage reference and local rail stabilization in sensor signal conditioning circuits.
For engineers reviewing the BZV55-B5V1,135 datasheet, BZV55-B5V1,135 pinout, BZV55-B5V1,135 application, or BZV55-B5V1,135 equivalent, key selection criteria include Zener voltage accuracy (±2 %), low dynamic impedance (40 Ω @ 5 mA), thermal resistance (300 K/W junction-to-solder-point), and SOD80C footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable DC voltage under varying load and temperature conditions. Its regulation performance is defined at IZ = 5 mA, with a temperature coefficient of −0.8 mV/K and reverse leakage current ≤2 µA at VR = 2 V.
The device features low capacitance (1.2 pF @ 1 MHz, 0 V), enabling use in low-noise analog references, and supports non-repetitive surge handling up to 40 W for 100 µs pulses - critical for transient suppression in power-supply feedback paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.0 V to 5.2 V at IZ = 5 mA - ensures tight 5.1 V nominal regulation for ±1% system reference stability |
| Differential Resistance (rdiff) | 400 Ω max / 40 Ω typ @ IZ = 5 mA - determines output impedance and load regulation error in shunt regulator designs |
| Temperature Coefficient (SZ) | −2.7 mV/K min / −0.8 mV/K typ - quantifies voltage drift over temperature; enables compensation in precision references |
| Total Power Dissipation (Ptot) | 400 mW @ Tamb ≤ 50 °C - defines maximum continuous DC power handling on standard FR4 PCB |
| Reverse Leakage Current (IR) | ≤2 µA @ VR = 2 V - limits quiescent current in battery-powered voltage monitor circuits |
| Junction-to-Solder-Point Thermal Resistance (Rth(j-sp)) | 300 K/W - determines thermal rise above PCB copper during sustained operation |
| Package | SOD80C - 3.3 mm × 1.45 mm hermetically sealed glass SMD outline with cathode band marking |
Pinout & Package
Hermetically sealed glass SOD80C package: 3.3 mm length × 1.45 mm width × 0.3 mm height; anode and cathode terminals exposed on opposite ends; cathode identified 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 rail; completes current path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance | Enables direct replacement in 5.1 V reference designs without recalibration or resistor trimming |
| Low differential resistance (40 Ω typ) | Reduces output voltage variation under ±10 mA load changes - critical for ADC reference buffering |
| Hermetic glass SOD80C package | Provides long-term parameter stability and moisture resistance vs. plastic-packaged Zeners |
| Non-repetitive peak power rating (40 W) | Supports transient overvoltage clamping in 100 µs surge events without degradation |
| 1.2 pF junction capacitance | Minimizes high-frequency coupling into sensitive analog nodes - suitable for op-amp reference inputs |
Applications
| Industrial Sensor Signal Conditioning | Microcontroller Reset Circuit Reference |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C5V1 | ±5 % tolerance, 600 mW Ptot, 130 Ω rdiff @ 5 mA | Higher power but looser regulation; suited for non-critical biasing | Select when cost priority outweighs voltage accuracy and thermal performance |
| MMSZ5231B | ±5 % tolerance, SOD-123 package, 500 mW Ptot, 17 Ω rdiff @ 20 mA | Lower rdiff but requires higher test current; plastic package less stable over time | Choose for higher-current shunt regulation where long-term drift is less critical than initial impedance |
Compared with BZV55-B5V1,135, BZX55C5V1 trades regulation accuracy for higher surge robustness, while MMSZ5231B offers lower impedance at higher current but lacks hermetic sealing - making the BZV55-B5V1,135 optimal for precision, long-life, low-drift 5.1 V references in industrial environments.

FAQ
What is the maximum continuous forward current for BZV55-B5V1,135?
The absolute maximum forward current is 250 mA per the datasheet limiting values table. However, this rating applies only to brief forward conduction events - the device is designed for reverse-bias Zener operation, and sustained forward current above 10 mA risks thermal overstress due to its 400 mW ambient-limited power dissipation.
Can BZV55-B5V1,135 be used in place of a 5.1 V voltage reference IC like REF5050?
No - it is not a drop-in replacement. The BZV55-B5V1,135 is a two-terminal shunt regulator with no active circuitry, offering no initial accuracy better than ±2 %, no temperature drift compensation, and no output current drive capability. It serves as a basic reference, not a precision IC-grade reference.
How does the SOD80C package affect thermal performance compared to DO-35?
The SOD80C's glass-body construction and solder-point thermal path yield Rth(j-sp) = 300 K/W - significantly lower than DO-35's typical 500+ K/W - enabling higher power density on compact PCBs. Its hermetic seal also eliminates moisture-induced parameter shift common in plastic DO-35 variants.
Is BZV55-B5V1,135 suitable for automotive applications?
No - the datasheet explicitly states this is a non-automotive qualified product. It has not undergone AEC-Q101 stress testing, lacks automotive-grade qualification documentation, and contains no automotive-specific reliability data. Use only in industrial, consumer, or commercial systems.
