Product details
Overview
BZV55-C3V0,135 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 3.0 V nominal regulation at 5 mA, with 325 Ω typical differential resistance and 400 mW total power dissipation at Tamb ≤ 50 °C. It delivers stable low-voltage reference in space-constrained consumer and industrial power rails.
For engineers reviewing the BZV55-C3V0,135 datasheet, BZV55-C3V0,135 pinout, BZV55-C3V0,135 application, or BZV55-C3V0,135 equivalent, this page provides verified electrical parameters, thermal behavior under transient surge, reverse leakage at 1 V (≤10 µA), and direct SOD80C footprint compatibility for rapid PCB integration.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 3.0 V reference across load variations, with temperature coefficient of −3.5 to −2.1 mV/K and low 0.9 V forward voltage at 10 mA. Its 325 Ω differential resistance ensures minimal output voltage drift under current changes.
Designed for low-power regulation, it supports non-repetitive peak reverse power dissipation up to 40 W (100 µs square wave) and exhibits 10 µA maximum reverse leakage at 1 V, enabling reliable operation in battery-backed and standby circuits.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5226BS-7-F | 3.0 V ±5 %, SOT-23 package, 225 mW Ptot, 300 Ω rdif | Lower power rating limits use in sustained 5 mA regulation; smaller footprint reduces thermal mass | Select when board space is critical and average power <200 mW |

FAQ
What is the maximum continuous Zener current for BZV55-C3V0,135 at 25 °C ambient?
The device supports up to 133 mA continuous Zener current at 25 °C ambient, calculated from its 400 mW power rating and 3.0 V nominal voltage (IZ(max) = 400 mW / 3.0 V). Derating applies above 50 °C ambient per the datasheet thermal curve.
Does BZV55-C3V0,135 meet RoHS and REACH requirements?
Yes - BZV55-C3V0,135 is manufactured in compliance with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations and halogen-free packaging confirmed in Nexperia's official compliance documentation.
Can BZV55-C3V0,135 be used in parallel for higher current capability?
No - Zener diodes exhibit manufacturing spread in breakdown voltage; paralleling BZV55-C3V0,135 units causes current hogging and thermal runaway. Use a single higher-power Zener or active regulation for >133 mA loads.
What is the cathode marking method on the SOD80C package?
The cathode is marked by a distinct black band on the glass body, aligned with Pin 1 per Nexperia's standardized SOD80C pinning diagram. This band must face the PCB silkscreen indicator or schematic cathode symbol during placement.
