Nexperia USA Inc. BZV55-B8V2,115

Overview

BZV55-B8V2,115 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 8.2 V Zener voltage with ±2 % tolerance, 40 Ω typical differential resistance at 5 mA, and 3.2 mV/K temperature coefficient - enabling stable biasing in sensor interfaces and power supply feedback loops.

For engineers reviewing the BZV55-B8V2,115 datasheet, BZV55-B8V2,115 pinout, BZV55-B8V2,115 application, or BZV55-B8V2,115 equivalent, this page provides verified electrical parameters, thermal behavior under transient surge (100 µs, 40 W), reverse leakage (700 nA at 5 V), and SOD80C footprint compatibility for PCB layout validation.

Technical Context

This Zener diode operates in reverse breakdown to maintain a stable reference voltage across its cathode-anode terminals. Its 8.04 V to 8.36 V working voltage range (min/max at I_Z = 5 mA) and low 40 Ω typical differential resistance ensure minimal voltage drift under load variation.

Thermal performance is defined by R_th(j-a) = 380 K/W (free air) and R_th(j-sp) = 300 K/W (solder point), supporting operation up to +200 °C junction temperature. Non-repetitive peak reverse power dissipation is rated at 40 W for 100 µs square-wave pulses at T_j = 25 °C.

FAQ

What is the maximum continuous power dissipation for BZV55-B8V2,115?

The BZV55-B8V2,115 has a total power dissipation limit of 500 mW when mounted on a 10 × 10 × 0.6 mm ceramic substrate at T_amb ≤ 50 °C. Derating applies above 50 °C ambient, following the specified thermal resistance of 380 K/W (junction-to-ambient).

How does the temperature coefficient affect regulation accuracy?

With a typical temperature coefficient of +3.2 mV/K, the BZV55-B8V2,115 exhibits a +0.26 V shift over a 80 °C temperature range (e.g., −25 °C to +55 °C). This is factored into system-level accuracy budgets for precision references, especially in unbuffered configurations.

Is BZV55-B8V2,115 suitable for surge protection applications?

Yes - it supports non-repetitive peak reverse power dissipation of 40 W for 100 µs square-wave pulses at T_j = 25 °C. It is commonly used for transient clamping in low-energy signal lines, but not for repetitive surge events or high-current AC line protection.

What is the cathode identification method on the SOD80C package?

The cathode is marked by a visible band on the glass body of the SOD80C package. Pin 1 (cathode) is always adjacent to this band; Pin 2 (anode) is the opposite end. This matches the simplified outline and graphic symbol in Nexperia's official pinning documentation.
