Product details
Overview
BZV55-B3V0,115 from Nexperia is a low-power Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 3.0 V nominal regulation at 5 mA with ±2 % tolerance, 325 Ω typical differential resistance, and −3.5 mV/K to −2.1 mV/K temperature coefficient - used for precision voltage reference and local supply rail stabilization in sensor signal conditioning circuits.
For engineers reviewing the BZV55-B3V0,115 datasheet, BZV55-B3V0,115 pinout, BZV55-B3V0,115 application, or BZV55-B3V0,115 equivalent, this page delivers verified electrical parameters, thermal behavior under transient surge, reverse leakage at 1 V (≤10 µA), forward voltage at 10 mA (≤0.9 V), and SOD80C mechanical footprint data required for layout validation and reliability assessment.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified nominal Zener voltage of 3.0 V at IZ = 5 mA, exhibiting a tight ±2 % tolerance band (2.94 V to 3.06 V) and low differential resistance (325 Ω typ., 600 Ω max.) to maintain stable regulation under load variation. Its negative temperature coefficient (−3.5 to −2.1 mV/K) enables predictable drift compensation in temperature-sensitive analog front-ends.
Designed for low-power applications, it supports non-repetitive peak reverse power dissipation up to 40 W for 100 µs pulses and total DC power dissipation up to 500 mW when mounted on a 10 × 10 × 0.6 mm ceramic substrate - with thermal resistance from junction to ambient of 380 K/W in free air.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage (VZ) | 3.0 V at IZ = 5 mA - defines precise regulation point for low-voltage reference generation |
| Zener Tolerance | ±2 % (B-series) - ensures voltage accuracy within 2.94 V to 3.06 V at 25 °C |
| Differential Resistance (rdif) | 325 Ω typ. at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Reverse Leakage Current (IR) | ≤10 µA at VR = 1 V - confirms low standby power loss in bias networks |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - enables use as clamping or protection diode in dual-role designs |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 µs square wave - supports transient overvoltage suppression without failure |
| Total Power Dissipation (Ptot) | 500 mW on ceramic substrate - sets maximum continuous DC power handling capability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C3V0 | ±5 % tolerance (2.85–3.15 V), higher rdif (up to 900 Ω), same SOD80C package | Lower cost for non-critical biasing where 3.0 V accuracy is secondary to budget constraints | Select when ±5 % regulation tolerance suffices and leakage <5 µA at 1 V is acceptable |
| MMSZ5226B | ±5 % tolerance, 3.3 V nominal, SOD-123 package (larger footprint, higher thermal mass) | Higher surge robustness (500 mW Ptot), suited for higher ambient temperature PCB locations | Choose for designs requiring >400 mW continuous dissipation or legacy SOD-123 layout compatibility |
Compared with BZV55-B3V0,115, BZX55C3V0 trades voltage accuracy for cost in non-critical biasing, while MMSZ5226B offers higher power handling in a physically larger package - making the BZV55-B3V0,115 optimal for space-constrained, precision 3.0 V reference needs with hermetic reliability.

FAQ
What is the maximum continuous reverse current this diode can sustain at 3.0 V?
The BZV55-B3V0,115 is not rated for continuous reverse current at its Zener voltage; it is designed for regulated voltage operation at IZ = 5 mA. Its absolute maximum limiting value is 250 mA forward current, but sustained reverse conduction beyond datasheet-specified test conditions risks thermal runaway due to its 500 mW power limit and 380 K/W junction-to-ambient thermal resistance.
Does this part meet automotive qualification standards?
No, the BZV55-B3V0,115 is not AEC-Q200 qualified. Nexperia explicitly states in the datasheet that unless otherwise specified, BZV55 series devices are non-automotive qualified and unsuitable for safety-critical or life-support automotive applications - though its hermetic SOD80C package supports extended temperature operation up to +200 °C junction.
How does the temperature coefficient affect regulation accuracy over −40 °C to +85 °C?
With a temperature coefficient of −3.5 to −2.1 mV/K, the BZV55-B3V0,115 exhibits a worst-case drift of approximately −127.5 mV over a 125 K span (−40 °C to +85 °C), translating to −4.25 % deviation from 3.0 V nominal. This must be factored into system-level calibration if sub-1 % reference stability is required across full industrial temperature range.
Can this diode be used in series or parallel configurations for higher voltage or current capability?
Series connection is feasible for higher voltage references but requires matched units to avoid current imbalance; parallel use is strongly discouraged due to negative temperature coefficient mismatch causing thermal runaway. The datasheet specifies operation only as a single-element Zener device - no derating curves or matching guidance are provided for multi-diode configurations.
