Product details
Overview
BZV55-C27,115 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in a hermetically sealed SOD80C glass SMD package, rated for 27 V nominal working voltage at 2 mA test current, 65 Ω typical differential resistance, and 50 mW total power dissipation at Tamb ≤ 50 °C. It delivers stable voltage reference in low-power analog circuits, power supply feedback loops, and overvoltage protection nodes.
For engineers reviewing the BZV55-C27,115 datasheet, BZV55-C27,115 pinout, BZV55-C27,115 application, or BZV55-C27,115 equivalent, this page provides verified electrical parameters, thermal behavior under surge conditions, SOD80C footprint details, and validated alternative parts for precision voltage regulation design.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 27 V reference across load variations, with temperature coefficient of +18.0 mV/K at IZ = 2 mA - indicating positive drift with junction temperature rise. Its low 65 Ω differential resistance ensures minimal output voltage variation under dynamic current changes.
Designed for surface-mount use on ceramic substrates (10 × 10 × 0.6 mm), it supports non-repetitive peak reverse power dissipation up to 40 W for 100 µs square-wave surges at Tj = 25 °C, and exhibits 50 pF diode capacitance at f = 1 MHz and VR = 0 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage (VZ) | 27 V at IZ = 2 mA - defines primary regulation point in feedback or clamp circuits |
| Differential Resistance (rdif) | 65 Ω typ. at IZ = 2 mA - determines output impedance and load regulation error |
| Temperature Coefficient (SZ) | +18.0 mV/K at IZ = 2 mA - quantifies voltage drift per degree Celsius rise in junction temperature |
| Total Power Dissipation (Ptot) | 400 mW at Tamb ≤ 50 °C - sets maximum continuous DC power handling on standard PCB layout |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W for 100 µs - enables transient overvoltage clamping without failure |
| Diode Capacitance (Cd) | 50 pF at f = 1 MHz, VR = 0 V - impacts high-frequency noise filtering and stability in feedback paths |
| Reverse Current (IR) | <50 nA at VR = 18.9 V (0.7 × VZ(nom)) - ensures low leakage in standby or precision bias networks |
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.

IC Role / Device Role / Timing Role: Supplies precise voltage to current-sense resistor network, defining LED drive level. Use Value: 65 Ω differential resistance limits current-setting error to <2 % across 0–20 mA load range, improving luminance uniformity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52-C27,115 | Same 27 V nominal voltage and ±5 % tolerance, but in SOD123 package with higher Ptot = 500 mW and Rth(j-a) = 300 K/W | Higher power handling suits continuous 2 mA regulation in thermally constrained layouts | Select when board space allows larger footprint and thermal management requires lower junction-to-ambient resistance |
| MMSZ5256ET1G | 27 V nominal, ±5 %, but in SOD123 with 500 mW Ptot, 30 Ω rdif, and −1.5 mV/K temperature coefficient | Negative tempco enables compensation of positive-drift components in mixed-technology references | Choose when tighter regulation stability over temperature is required and SOD123 mounting is acceptable |
Compared with BZV55-C27,115, BZT52-C27,115 offers better thermal performance in compact designs, while MMSZ5256ET1G provides superior low-drift regulation - both require footprint redesign but retain identical voltage function and tolerance.

FAQ
What is the maximum continuous forward current for BZV55-C27,115?
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 region for regulation.
Can BZV55-C27,115 be used in place of a 24 V Zener diode?
No - BZV55-C27,115 is specified for 27 V nominal Zener voltage at 2 mA, with min/max range of 25.1 V to 28.9 V. Substituting it for a 24 V part introduces ~12.5 % voltage error, violating regulation accuracy requirements in feedback or clamp circuits.
What is the thermal resistance from junction to solder point (Rth(j-sp)) for this device?
Rth(j-sp) is 300 K/W, as specified in Table 6. This value applies when mounted on a ceramic substrate (10 × 10 × 0.6 mm) and reflects heat transfer efficiency from die to PCB solder joint - critical for estimating junction temperature rise under pulsed surge conditions.
Does BZV55-C27,115 meet automotive qualification standards?
No - the datasheet explicitly states "Non-automotive qualified products" in Section 12.3. It is not tested to AEC-Q200, lacks automotive-grade screening, and carries no warranty for use in safety-critical or vehicle-mounted systems.
