Product details
Overview
BZV55-B11,135 from Nexperia is a 11 V ±2 % tolerance silicon Zener diode in a hermetically sealed SOD80C glass SMD package, rated for 500 mW total power dissipation and 85 mA nominal Zener test current (IZ = 5 mA), used for precision voltage regulation and reference in low-power analog circuits such as sensor biasing and ADC reference stabilization.
For engineers reviewing the BZV55-B11,135 datasheet, BZV55-B11,135 pinout, BZV55-B11,135 application, or BZV55-B11,135 equivalent, this page delivers verified electrical parameters, thermal behavior, SOD80C footprint details, reverse leakage at 8 V, differential resistance of 50–150 Ω, and real-world use cases in industrial signal conditioning and portable power management.
Technical Context
This Zener diode operates in reverse breakdown with a nominal Zener voltage of 11 V at IZ = 5 mA, exhibiting a temperature coefficient of +5.4 to +9.0 mV/K and low differential resistance (50–150 Ω) for stable regulation under varying load currents. Its glass SOD80C package ensures hermetic sealing and reliable performance in humid or chemically aggressive environments.
It supports non-repetitive surge handling up to 40 W for 100 µs pulses and maintains reverse leakage ≤100 nA at VR = 8 V, enabling accurate low-current reference operation in battery-powered systems where quiescent current matters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10.8 V to 11.2 V at IZ = 5 mA - tight ±2 % tolerance enables precise voltage clamping in feedback loops. |
| Differential Resistance (rdif) | 50 Ω to 150 Ω at IZ = 5 mA - low impedance ensures minimal output voltage shift across load variations. |
| Reverse Leakage (IR) | ≤100 nA at VR = 8 V - ultra-low leakage preserves accuracy in high-impedance reference nodes. |
| Total Power Dissipation (Ptot) | 500 mW at Tj ≤50 °C on ceramic substrate - defines maximum continuous DC power handling in PCB-mounted applications. |
| Non-repetitive Peak Power (PZSM) | 40 W for tp = 100 µs - supports transient overvoltage suppression without device failure. |
| Thermal Resistance (Rth(j-a)) | 380 K/W in free air - determines junction-to-ambient temperature rise under steady-state bias. |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - specifies anode-cathode conduction threshold when used in forward-biased protection roles. |
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 where Zener breakdown occurs. |
| 2 | Anode | Connected to ground or lower-potential rail; completes reverse-bias path for regulation. |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance | Enables direct replacement in precision references without recalibration or trimming. |
| Hermetic glass SMD construction | Prevents moisture ingress and parameter drift in long-life industrial deployments. |
| Low differential resistance (50–150 Ω) | Reduces output voltage variation under ±1 mA load current changes in feedback networks. |
| Non-repetitive 40 W surge rating | Withstands ESD transients and inductive kickback without degradation in sensor interface circuits. |
Applications
| Industrial Sensor Signal Conditioning | Portable Device Voltage Reference |

IC Role / Device Role / Timing Role: Shunt protector absorbing short-duration surges before downstream LDOs or microcontrollers. Use Value: Limits voltage to ≤11.5 V for 100 µs using 40 W peak rating, preventing latch-up in 3.3 V logic interfaces. |
Use Scenario: Setting regulated 5 V output in adjustable buck converter feedback network (e.g., LM2678-based supply). IC Role / Device Role / Timing Role: Zener element in resistor divider that sets FB pin voltage to trigger PWM controller regulation. Use Value: Delivers ±0.2% output stability across 0–85 °C due to matched temperature coefficient with feedback resistors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5240B (ON Semiconductor) | Same 11 V ±5 % tolerance, SOT-23 package, 225 mW Ptot - lower power rating and wider tolerance. | Not suitable for precision reference use; acceptable only for coarse clamping where 5 % error is tolerable. | Select only if board space requires SOT-23 and regulation accuracy >±2 % is unnecessary. |
| BZX84-C11 (Nexperia) | 11 V ±5 %, SOT-23, 300 mW Ptot, higher IR (≤1 µA at VR = 8 V) - looser tolerance and higher leakage. | Limited to non-critical biasing; cannot replace BZV55-B11,135 in metrology-grade references. | Choose only for cost-sensitive consumer designs where 1 µA leakage and ±5 % VZ meet system specs. |
Compared with MMBZ5240B and BZX84-C11, BZV55-B11,135 delivers tighter ±2 % tolerance, lower 100 nA leakage, and higher 500 mW power handling - making it uniquely suited for industrial-grade voltage references where long-term stability and low drift are mandatory.

FAQ
What is the maximum continuous Zener current for BZV55-B11,135?
The device supports a maximum continuous Zener current of 85 mA at 25 °C ambient when mounted on a 10 × 10 × 0.6 mm ceramic substrate, derived from its 500 mW total power dissipation rating and 11 V nominal Zener voltage (IZmax ≈ 500 mW / 11 V). Derating applies above 50 °C ambient per thermal resistance data.
Does BZV55-B11,135 require external heat sinking?
No external heat sink is required. With Rth(j-a) = 380 K/W in free air and Ptot = 500 mW, junction temperature rise is ~190 K above ambient - but the rated 500 mW applies only at Tamb ≤50 °C on specified ceramic substrate. In typical PCB layouts, thermal relief via copper pour suffices for continuous 40–50 mA operation.
Can BZV55-B11,135 be used in place of a 10 V Zener diode?
No - its nominal Zener voltage is strictly 11 V (10.8–11.2 V range), not 10 V. Substituting it for a 10 V part would raise regulated voltage by ~10 %, potentially exceeding IC absolute maximum ratings or violating feedback loop setpoints. Use BZV55-B10,135 for 10 V applications.
Is the SOD80C package compatible with standard reflow soldering profiles?
Yes - Nexperia specifies compatibility with JEDEC J-STD-020D reflow profiles. The SOD80C outline supports peak temperatures up to 260 °C for ≤10 seconds, with recommended solder paste stencil apertures of 2.30 × 0.90 mm per pad and 0.12 mm thickness per Figure 7 in the datasheet.
