Product details
Overview
BZV55-B4V7,135 from Nexperia is a low-power Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 4.7 V nominal regulation at 5 mA with ±2 % tolerance, 425 Ω typical differential resistance, and −1.4 mV/K temperature coefficient. It delivers stable reference voltage in low-current bias networks for power supply feedback, sensor excitation, and analog signal conditioning circuits.
For engineers reviewing the BZV55-B4V7,135 datasheet, BZV55-B4V7,135 pinout, BZV55-B4V7,135 application, or BZV55-B4V7,135 equivalent, this page provides verified electrical parameters, thermal behavior under transient surge (40 W, 100 µs), reverse leakage (≤3 µA at VR = 2 V), forward voltage (≤0.9 V @ 10 mA), and SOD80C mechanical layout - all confirmed from Nexperia's official Rev. 5 product data sheet dated 26 January 2011.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 4.7 V reference across load variations and temperature shifts. Its −1.4 mV/K temperature coefficient minimizes drift over −65 °C to +200 °C junction range, while low 425 Ω differential resistance ensures tight regulation under dynamic current changes up to 250 mA forward or 6.0 A non-repetitive surge.
The SOD80C package enables reliable reflow soldering with defined footprint (3.3–3.7 mm length, 1.45–1.60 mm width, 0.3 mm height) and thermal resistance of 300 K/W (junction-to-solder point), supporting operation at up to 500 mW total power dissipation when mounted on a 10 × 10 × 0.6 mm ceramic substrate.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 4.7 V ±2 % at IZ = 5 mA - precise reference for feedback loops and voltage clamping |
| Differential Resistance | 425 Ω typ. at IZ = 5 mA - low impedance ensures minimal output voltage variation with current change |
| Temperature Coefficient | −1.4 mV/K - negative drift partially compensates for other circuit components' positive drift |
| Reverse Leakage Current | ≤3 µA at VR = 2 V - low leakage preserves accuracy in high-impedance bias networks |
| Non-repetitive Peak Power | 40 W for tp = 100 µs - handles short transients without degradation |
| Total Power Dissipation | 500 mW at Tj ≤ 50 °C on ceramic substrate - defines continuous thermal design margin |
| Forward Voltage | ≤0.9 V at IF = 10 mA - enables use as low-drop rectifier or clamp in dual-role circuits |
Pinout & Package
Hermetically sealed glass SOD80C package: 3.7 mm × 1.6 mm × 0.3 mm body, cathode marked by band, optimized for automated SMT assembly and reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; polarity marking band identifies this terminal |

Key Features
| Feature | Design Value |
|---|---|

Applications
| Power Supply Feedback | Sensor Excitation Reference |
|---|---|
|
Use Scenario: Regulating output voltage in discrete linear regulators or optocoupler-based SMPS feedback paths. IC Role / Device Role / Timing Role: Zener reference element providing stable 4.7 V threshold for error amplifier comparison. Use Value: Tight ±2 % tolerance and low 425 Ω dynamic resistance ensure <±10 mV output deviation across line/load variations. |
Use Scenario: Biasing resistive sensors (e.g., RTDs, strain gauges) requiring stable excitation voltage. IC Role / Device Role / Timing Role: Precision voltage source delivering constant 4.7 V to sensor bridge arms. Use Value: −1.4 mV/K tempco counterbalances typical RTD positive drift, reducing system-level calibration burden. |
| Analog Signal Clamping | Microcontroller I/O Protection |
|
Use Scenario: Limiting analog input swing to prevent ADC saturation or op-amp rail-to-rail overload. IC Role / Device Role / Timing Role: Reverse-biased shunt clamp limiting voltage to 4.7 V above ground. Use Value: 40 W surge rating absorbs fast transients (e.g., relay bounce, cable discharge) without failure. |
Use Scenario: Protecting 5 V-tolerant GPIO pins from overvoltage events in mixed-voltage systems. IC Role / Device Role / Timing Role: Low-leakage (≤3 µA) Zener clamping excess voltage to safe 4.7 V level. Use Value: Sub-µA leakage avoids loading sensitive inputs; glass package ensures reliability over 10+ year field life. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C4V7 | ±5 % tolerance, 550 Ω rdif, −2.5 mV/K tempco - looser accuracy, higher drift | Acceptable where cost > precision; unsuitable for closed-loop feedback demanding <±1 % regulation | Select only if budget constraints outweigh regulation stability requirements |
| MMSZ4704T1G | ±5 % tolerance, SOD-123 package, 600 Ω rdif, −2.0 mV/K - larger footprint, higher thermal resistance (400 K/W) | Compatible for board space with less stringent thermal limits; not drop-in due to different pad layout | Choose when existing design uses SOD-123 footprints and ±5 % is acceptable |
Compared with BZV55-B4V7,135, BZX55C4V7 trades regulation accuracy for lower unit cost, while MMSZ4704T1G offers similar performance in a larger package with inferior thermal performance - making the BZV55-B4V7,135 optimal for space-constrained, thermally demanding, precision-bias applications.

FAQ
What is the maximum continuous power dissipation for BZV55-B4V7,135?
The BZV55-B4V7,135 has a total power dissipation limit of 500 mW when mounted on a 10 × 10 × 0.6 mm ceramic substrate at ambient temperatures ≤50 °C. Derating is required above this temperature per the Rth(j-a) = 380 K/W specification, and actual usable power depends on PCB copper area and airflow.
How does the −1.4 mV/K temperature coefficient affect circuit performance?
The negative temperature coefficient means the Zener voltage decreases by approximately 1.4 mV per degree Celsius rise in junction temperature. This characteristic can offset positive drift in associated components (e.g., op-amps or resistors), improving overall system stability - especially in unregulated environments like industrial enclosures.
Can BZV55-B4V7,135 be used in place of a 5 V logic-level shifter?
No - it is not designed for bidirectional level translation. As a passive Zener diode, it regulates or clamps only in reverse bias and lacks active drive capability, direction control, or speed optimization required for digital signal shifting. Use dedicated level-shifter ICs instead.
Is the SOD80C package compatible with standard reflow profiles?
Yes - Nexperia specifies full compatibility with JEDEC J-STD-020D reflow profiles. The SOD80C footprint (3.3–3.7 mm length, 1.45–1.60 mm width) supports standard stencil design, and the glass body withstands peak temperatures up to 260 °C for ≤30 seconds without cracking or parameter shift.
