Product details
Overview
BZV55-B27,115 from Nexperia is a low-power Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 27 V nominal working voltage with ±2 % tolerance, 500 mW total power dissipation, and 65 Ω typical differential resistance at IZ = 2 mA. It serves as a precision reference or shunt regulator in low-current biasing, voltage clamping, and overvoltage protection circuits for industrial sensor interfaces and power supply feedback networks.
For engineers reviewing the BZV55-B27,115 datasheet, BZV55-B27,115 pinout, BZV55-B27,115 application, or BZV55-B27,115 equivalent, key selection criteria include its 27 V regulation accuracy, low thermal coefficient (±18 mV/K), SOD80C footprint compatibility, and non-repetitive surge capability up to 40 W for 100 µs pulses.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled VZ = 26.5–27.5 V at IZ = 2 mA, exhibiting a temperature coefficient of +18.0 to +25.3 mV/K and low dynamic impedance (65–300 Ω) across operating current range. Its hermetic glass construction ensures stable long-term regulation performance under thermal cycling and humidity exposure.
The device features a two-terminal configuration optimized for shunt regulation: anode and cathode terminals define unidirectional conduction, with the marking band indicating cathode polarity. Thermal resistance from junction to ambient is 380 K/W in free air, limiting continuous power handling without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 27 V (26.5–27.5 V min/max at IZ = 2 mA; enables precise 27 V reference generation) |
| Tolerance | ±2 % (B-series grade; supports tight-voltage-margin designs without post-calibration) |
| Differential Resistance | 65 Ω typ. (at IZ = 2 mA; ensures <1.5 V output variation over 10 mA load change) |
| Total Power Dissipation | 500 mW (Tamb ≤ 50 °C on ceramic substrate; defines maximum continuous DC regulation power) |
| Non-repetitive Peak Power | 40 W (100 µs square wave; allows transient overvoltage suppression without failure) |
| Reverse Leakage Current | 50 nA max. (at VR = 0.7 × VZ; minimizes quiescent current in battery-powered references) |
| Thermal Resistance (j-a) | 380 K/W (free-air; dictates derating curve above 50 °C ambient) |
Pinout & Package
Hermetically sealed glass SOD80C package: 3.3–3.7 mm length, 1.45–1.60 mm width, 0.3 mm height; cathode marked by single band.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C27 | ±5 % tolerance, 100 Ω typical rdif, 600 mW Ptot | Higher voltage drift and looser regulation; suitable only for non-critical biasing | Select when cost sensitivity outweighs regulation accuracy and thermal stability needs |
| MMSZ5256B | SOD-123 package, 27 V ±5 %, 500 mW, 300 Ω rdif, 100 nA IR | Larger footprint, higher leakage, lower surge rating (25 W) | Choose only if SOD-123 layout compatibility is mandatory and 27 V ±2 % is not required |
Compared with BZX55C27 and MMSZ5256B, BZV55-B27,115 delivers tighter voltage control, lower dynamic impedance, and superior surge resilience-making it the preferred choice for precision reference and robust protection where ±2 % tolerance and 40 W pulse handling are design-critical.

FAQ
What is the maximum continuous reverse current the BZV55-B27,115 can sustain at 25 °C?
The device supports a maximum continuous forward current of 250 mA, but for Zener operation, the recommended test current is 2 mA. At this point, the Zener voltage is specified as 26.5–27.5 V. Continuous reverse current must be limited to maintain junction temperature below 200 °C; with 500 mW total dissipation and 27 V VZ, the practical upper limit is ~18.5 mA under ideal heatsinking conditions.
Does the BZV55-B27,115 meet automotive AEC-Q200 requirements?
No. The BZV55-B27,115 is not AEC-Q200 qualified. Nexperia explicitly states in its datasheet that unless otherwise specified, BZV55 series devices are non-automotive qualified and unsuitable for safety-critical or automotive applications. For automotive use, consider Nexperia's AEC-Q200-certified PZM series or similar qualified Zeners.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
At IZ = 2 mA, the temperature coefficient ranges from +18.0 to +25.3 mV/K. Over a 165 °C span, this introduces a potential VZ shift of +2.97 V to +4.17 V - approximately +11 % to +15 % deviation from nominal 27 V. For high-stability designs, operation near 25 °C or active compensation is advised.
Can the BZV55-B27,115 replace a 1N4733A in existing PCB layouts?
No. The 1N4733A uses DO-41 through-hole packaging, while BZV55-B27,115 is SOD80C surface-mount with 3.3–3.7 mm body length and 1.45–1.60 mm width. Footprint, soldering process, and thermal management differ fundamentally. Direct replacement requires board redesign; however, electrical parameters (27 V, ±2 %, 500 mW) are functionally compatible.
