Product details
Overview
BZV55-C75,135 from Nexperia is a 75 V ±5 % tolerance Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 400 mW total power dissipation at ≤50 °C ambient, with 170 Ω typical differential resistance at IZ = 2 mA and −95 mV/K temperature coefficient, used for precision low-power voltage reference and regulation in sensor biasing and analog front-end circuits.
For engineers reviewing the BZV55-C75,135 datasheet, BZV55-C75,135 pinout, BZV55-C75,135 application, or BZV55-C75,135 equivalent, key selection criteria include nominal Zener voltage (75 V), tolerance (±5 %), thermal resistance (300 K/W junction-to-solder point), reverse leakage current (≤50 nA at 0.7×VZ), and SOD80C package compatibility with reflow soldering footprints.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable DC voltage under varying load and temperature conditions. Its −95 mV/K temperature coefficient indicates strong negative drift, requiring compensation in high-accuracy references, while its 170 Ω differential resistance at 2 mA defines output impedance and load regulation error.
The device supports non-repetitive surge handling up to 40 W for 100 µs pulses and delivers ≤50 nA reverse leakage at 0.7×VZ, enabling low-current bias networks. Its SOD80C package provides hermetic sealing for long-term stability in humid or corrosive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 75 V nominal, ±5 % tolerance - sets precise regulation point for 70–79 V operating range |
| Differential Resistance (rdif) | 170 Ω typical at IZ = 2 mA - determines output impedance and load regulation sensitivity |
| Temperature Coefficient (SZ) | −95 mV/K - quantifies voltage drift per degree Celsius, critical for thermal stability design |
| Total Power Dissipation (Ptot) | 400 mW at Tamb ≤ 50 °C - defines maximum continuous DC power in standard PCB mounting |
| Reverse Leakage Current (IR) | ≤50 nA at VR = 52.5 V (0.7×VZ) - ensures minimal quiescent current in high-impedance bias networks |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 µs square wave - enables transient overvoltage clamping without failure |
| Thermal Resistance (Rth(j-sp)) | 300 K/W junction-to-solder point - governs temperature rise above PCB copper under steady-state load |
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 reverse-bias path for regulation current |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass SMD packaging | Ensures long-term parameter stability and moisture resistance in industrial environments |
| ±5 % Zener voltage tolerance | Supports cost-sensitive applications where tight regulation is not required but repeatability matters |
| Low reverse leakage (≤50 nA) | Enables use in ultra-low-power sensor biasing and battery-operated reference circuits |
| 40 W non-repetitive surge rating | Provides robustness against ESD and line transients without external TVS supplementation |
| 300 K/W junction-to-solder-point Rth | Allows predictable thermal modeling when mounted on standard 10×10 mm ceramic substrate |
Applications
| Industrial Sensor Biasing | ADC Reference Stabilization |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55-C75 | Same 75 V ±5 % rating, but in larger DO-35 axial package; higher Ptot (500 mW) and Rth(j-a) (500 K/W) | Requires through-hole assembly; better suited for prototyping or high-temperature ambient (>70 °C) where SMD thermal limits are exceeded | Select when board space allows axial components and thermal margin is constrained by ambient airflow |
| MMSZ5265B | 75 V ±5 % in SOD-123; lower rdif (100 Ω typ), higher IR (1 µA at 52.5 V), same Ptot (500 mW) | Higher leakage reduces suitability for nanoampere-bias applications but improves regulation linearity at >5 mA currents | Prefer for higher-current regulation where tighter dynamic impedance outweighs leakage penalty |
Compared with BZV55-C75,135, BZX55-C75 trades SMD compatibility for higher power and simpler thermal management, while MMSZ5265B offers improved regulation linearity at the cost of 20× higher reverse leakage-making BZV55-C75,135 optimal for low-leakage, space-constrained, and humidity-sensitive designs.

FAQ
What is the maximum continuous Zener current for BZV55-C75,135 at 25 °C ambient?
The device supports up to 5.3 mA continuous Zener current at 25 °C ambient, calculated from Ptot = 500 mW (Tj ≤ 200 °C limit) and VZ = 75 V. At rated 400 mW (Tamb ≤ 50 °C), maximum continuous current is 5.3 mA, consistent with datasheet thermal derating curves and absolute maximum ratings.
Can BZV55-C75,135 be used in place of BZV55-B75 in a circuit requiring tighter voltage tolerance?
No-BZV55-C75,135 has ±5 % tolerance (70–79 V), whereas BZV55-B75 offers ±2 % (73.5–76.5 V). Substituting introduces up to ±3 % additional voltage uncertainty, potentially violating regulation window requirements in precision references or feedback loops calibrated for B-grade tolerance.
Does the SOD80C package support automated optical inspection (AOI) after reflow?
Yes-the hermetically sealed glass body and distinct cathode marking band provide high contrast and consistent geometry, enabling reliable AOI detection of placement, polarity, and solder joint integrity per IPC-A-610 Class 2 standards on standard SMT lines.
How does the −95 mV/K temperature coefficient impact long-term voltage stability in a 0–60 °C operating range?
Over 60 °C ΔT, the Zener voltage shifts −5.7 V (−95 mV/K × 60 K), resulting in a 7.6 % deviation from nominal 75 V. System-level calibration or complementary temperature-compensated designs are required to maintain <±0.5 % regulation accuracy across this range.
