Product details
Overview
BZV55-B11,115 from Nexperia is a low-power Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, designed for precision voltage reference and regulation in low-current analog circuits. It delivers a nominal 11 V Zener voltage with ±2 % tolerance (B-series), 50 Ω typical differential resistance at 5 mA, −20 mV/K temperature coefficient, and supports up to 400 mW total power dissipation at ≤50 °C ambient - used in power supply feedback loops and sensor biasing.
For engineers reviewing the BZV55-B11,115 datasheet, BZV55-B11,115 pinout, BZV55-B11,115 application, or BZV55-B11,115 equivalent, this page provides verified electrical parameters, thermal behavior under transient surge, cathode/anode terminal mapping, SOD80C footprint compatibility, and validated alternatives for voltage reference design.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable DC voltage across its terminals under varying load and input conditions. Its low differential resistance (50 Ω typ. at IZ = 5 mA) ensures minimal output voltage drift with current changes, while the negative temperature coefficient (−20 mV/K) enables predictable thermal compensation in reference circuits.
The device is rated for non-repetitive peak reverse power dissipation of 40 W (100 µs square wave, Tj = 25 °C), with total power dissipation limited to 400 mW at ambient ≤50 °C on ceramic substrate. Its 150 pF junction capacitance (f = 1 MHz, VR = 0 V) and 100 nA reverse leakage at 8 V make it suitable for low-noise, low-frequency regulation - not RF or high-speed switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10.8 V to 11.2 V at IZ = 5 mA - defines precise regulation point for feedback networks |
| Differential Resistance (rdif) | 50 Ω typical at IZ = 5 mA - determines output impedance and load regulation error |
| Temperature Coefficient (SZ) | −20 mV/K at IZ = 5 mA - enables thermal drift prediction and compensation design |
| Reverse Leakage Current (IR) | 100 nA max at VR = 8 V - ensures minimal quiescent current in high-impedance bias paths |
| Total Power Dissipation (Ptot) | 400 mW at Tamb ≤50 °C on ceramic substrate - sets maximum continuous operating power |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 µs pulse - defines surge handling capability in transient protection roles |
| Junction-to-Ambient Rth | 380 K/W in free air - informs thermal derating requirements for PCB layout |

Use Scenario: Stabilizing output voltage in linear regulators and switching converter feedback networks. IC Role / Device Role / Timing Role: Zener voltage reference element in TL431-like shunt regulator configurations. Use Value: Maintains ±1 % output accuracy over temperature and line variations due to tight 11 V tolerance and low rdif. |
Use Scenario: Providing stable excitation voltage to resistive sensors (e.g., RTDs, strain gauges). IC Role / Device Role / Timing Role: Precision DC bias source replacing higher-cost IC references in analog front-ends. Use Value: Delivers 11 V ±0.22 V with <100 nA leakage, minimizing self-heating and measurement offset errors. |

Use Scenario: Generating clean reset signals during power-up and brown-out conditions. IC Role / Device Role / Timing Role: Stable threshold element in RC-based reset generator circuits. Use Value: Ensures reliable reset assertion at 11 V with predictable −20 mV/K drift, avoiding false triggers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C11,113 | ±5 % tolerance (C-series), 110 Ω typical rdif, same SOD80C package | Higher voltage drift and lower regulation precision; suited for cost-sensitive non-critical references | Select when ±5 % tolerance and relaxed load regulation are acceptable |
| MMSZ5240B-TP | ±5 % tolerance, 200 mW Ptot, SOD-123 package, 170 Ω rdif | Lower power rating and higher impedance limit use in higher-current or precision roles | Choose only for space-constrained designs where 11 V ±5 % suffices and power <200 mW |
Compared with BZV55-B11,115, the BZX55C11,113 trades tighter regulation for lower cost, while MMSZ5240B-TP sacrifices both precision and power handling for smaller footprint - making the BZV55-B11,115 optimal for industrial-grade 11 V references requiring stability, surge resilience, and thermal predictability.

FAQ
What is the maximum continuous forward current for BZV55-B11,115?
The absolute maximum forward current is 250 mA per datasheet Table 5. However, forward conduction is not its intended operating mode; sustained forward bias risks thermal runaway and permanent degradation. It must be operated in reverse-biased Zener breakdown for regulation.
Can BZV55-B11,115 be used in place of a 12 V Zener diode?
No - its nominal Zener voltage is 11 V (10.8–11.2 V range), not 12 V. Substituting it for a 12 V part would cause undershoot in regulation targets. For 12 V, use BZV55-B12,115 (11.8–12.2 V). Voltage mismatch exceeds system tolerance in precision feedback loops.
How does the −20 mV/K temperature coefficient affect circuit performance?
It causes the Zener voltage to decrease by ~20 mV per Kelvin rise in junction temperature. At 75 °C junction (50 °C above 25 °C reference), VZ drops ~1 V - requiring thermal design (e.g., heatsinking, layout spacing) or compensation techniques (e.g., series thermistor) in high-stability applications.
Is BZV55-B11,115 suitable for automotive applications?
No - the datasheet explicitly states "Non-automotive qualified products" and confirms no AEC-Q200 qualification. Its thermal and reliability testing does not meet automotive stress requirements. Use automotive-qualified Zeners like BZX84-A11 or PZM11NB for vehicle systems.
