Product details
Overview
BZV55-C11,135 from Nexperia is a ±5% tolerance silicon Zener diode in a hermetically sealed SOD80C glass SMD package, rated for 11 V nominal Zener voltage at 5 mA, 85 Ω typical differential resistance, and 100 nA reverse leakage at 8 V. It delivers low-power voltage regulation in space-constrained consumer and industrial power rails.
For engineers reviewing the BZV55-C11,135 datasheet, BZV55-C11,135 pinout, BZV55-C11,135 application, or BZV55-C11,135 equivalent, this page provides verified electrical parameters, thermal behavior under surge conditions, SOD80C footprint compatibility, and validated alternative parts for precision reference and clamping use cases.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under varying load and temperature conditions. Its 11 V nominal Zener voltage is specified at IZ = 5 mA with ±5% tolerance, and it exhibits a positive temperature coefficient of +5.4 mV/K at that current.
The device supports non-repetitive peak reverse power dissipation up to 40 W for 100 µs pulses and sustains total power dissipation of 500 mW at Tamb ≤ 50 °C on a ceramic substrate. Its differential resistance of 85 Ω (typ) ensures tight regulation under small-signal variations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 11 V nominal at IZ = 5 mA; ±5% tolerance band defines usable regulation window (10.4–11.6 V) |
| Differential Resistance (rdif) | 85 Ω typical at IZ = 5 mA; determines output impedance and load regulation error |
| Reverse Leakage (IR) | 100 nA max at VR = 8 V; critical for low-power standby circuits and high-impedance bias networks |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 µs square wave; enables transient overvoltage clamping without failure |
| Total Power Dissipation (Ptot) | 500 mW at Tamb ≤ 50 °C on 10×10×0.6 mm ceramic; sets continuous DC bias limit |
| Thermal Resistance (Rth(j-a)) | 380 K/W in free air; governs junction temperature rise under steady-state operation |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA; relevant for polarity protection or dual-use rectifier applications |
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 required (e.g., supply rail monitoring) |
| Low differential resistance (85 Ω typ) | Minimizes output voltage shift under ±1 mA load variation, improving stability in feedback paths |
| SOD80C hermetic glass package | Provides moisture resistance and long-term parameter stability vs. plastic-packaged alternatives |
| 40 W non-repetitive surge capability | Allows integration into input-stage ESD/overvoltage protection without external TVS devices |
Applications
| Power Supply Reference | Overvoltage Clamp |
|---|---|

IC Role / Device Role / Timing Role: Provides precise 11 V reference point for error amplifier comparison. Use Value: Maintains ±5% output accuracy across temperature and line variations without active compensation. |
Use Scenario: Protecting microcontroller I/O pins from 12 V rail transients in automotive body control modules.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZV55-B11,115 | ±2% tolerance (10.8–11.2 V), 50 Ω rdif, 2.5 µA IR at 8 V | Higher precision, higher leakage; suited for feedback references demanding tighter regulation | Select when voltage accuracy outweighs leakage sensitivity and cost constraints allow premium tolerance |
| MMBZ5240BS-7-F | ±5% tolerance (11 V), 150 Ω rdif, 100 nA IR, SOT-323 package | Larger differential resistance, same leakage; smaller footprint but higher thermal resistance | Choose for ultra-compact layouts where 380 K/W Rth(j-a) is acceptable and board area is constrained |
Compared with BZV55-C11,135, the BZV55-B11,115 offers tighter regulation at higher leakage cost, while MMBZ5240BS-7-F trades thermal performance for footprint reduction-neither matches its combination of hermetic stability, 85 Ω regulation, and 40 W surge handling in SOD80C.

FAQ
What is the maximum continuous power dissipation for BZV55-C11,135 at 70 °C ambient?
At Tamb = 70 °C, derating applies: Ptot drops linearly from 500 mW at 50 °C to 0 mW at 150 °C. Using the 100 °C derating slope (5 mW/°C), maximum dissipation is 400 mW. This assumes mounting on a 10×10×0.6 mm ceramic substrate per datasheet condition.
Can BZV55-C11,135 be used in place of a 12 V Zener diode?
No-its nominal Zener voltage is 11 V with ±5% tolerance (10.4–11.6 V), falling outside the 12 V specification. Substituting it for a 12 V part would cause under-regulation in feedback loops or insufficient clamping margin. Use BZV55-C12,135 for 12 V applications.
How does the temperature coefficient affect regulation accuracy over –40 °C to +125 °C?
With +5.4 mV/K coefficient at 5 mA, VZ shifts +447 mV from –40 °C to +125 °C (165 K delta). That represents ~4% drift relative to 11 V nominal-acceptable for non-critical biasing but insufficient for precision references requiring <1% total error.
Is the SOD80C package compatible with standard reflow soldering profiles?
Yes-the SOD80C outline is qualified for lead-free reflow per J-STD-020. Recommended profile uses peak temperature ≤260 °C, time above liquidus 60–150 s, and ramp rate ≤3 °C/s. Figure 7 in the datasheet provides exact land pattern dimensions for reliable solder joint formation.
