Nexperia USA Inc. BZV55-B2V7,115

Overview

BZV55-B2V7,115 from Nexperia is a low-power Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 2.7 V nominal regulation at 5 mA with ±2 % tolerance, 300 Ω typical differential resistance, and −2.0 mV/K temperature coefficient. It delivers stable reference voltage in low-current bias networks, power supply feedback loops, and overvoltage protection circuits for consumer and industrial electronics.

For engineers reviewing the BZV55-B2V7,115 datasheet, BZV55-B2V7,115 pinout, BZV55-B2V7,115 application, or BZV55-B2V7,115 equivalent, key selection criteria include its 2.7 V Zener voltage tolerance, 500 mW total power dissipation, 40 W non-repetitive surge capability, cathode-anode polarity marking, and SOD80C thermal performance on ceramic substrates.

Technical Context

This Zener diode operates in reverse breakdown to maintain a precise DC reference voltage under varying load and temperature conditions. Its −2.0 mV/K temperature coefficient ensures predictable drift across −65 °C to +200 °C junction temperature range, while low 300 Ω differential resistance minimizes output voltage variation with current changes from 1 mA to 5 mA.

The device uses a planar silicon junction structure optimized for stability and low noise in analog reference applications. Its SOD80C package provides hermetic sealing for moisture resistance and consistent thermal resistance (R_th(j-a) = 380 K/W in free air), enabling reliable operation in compact PCB layouts without forced cooling.

FAQ

What is the maximum continuous Zener current for BZV55-B2V7,115 at 25 °C ambient?

The device supports up to 250 mA forward current, but Zener operation is limited by power dissipation: at 25 °C ambient, maximum continuous Zener current is 185 mA (500 mW ÷ 2.7 V). Derating applies above 50 °C ambient per the 380 K/W thermal resistance specification.

How does the −2.0 mV/K temperature coefficient affect circuit performance at 85 °C junction temperature?

From 25 °C to 85 °C ΔT = 60 K, resulting in −120 mV shift (−2.0 mV/K × 60 K). For a 2.7 V nominal Zener, this yields ~2.58 V output at 85 °C junction - a −4.4 % change that must be accommodated in reference-dependent analog signal chains.

Can BZV55-B2V7,115 replace BZV55-C2V7 in an existing design?

No - BZV55-C2V7 has ±5 % tolerance (2.5–2.9 V), while BZV55-B2V7,115 is ±2 % (2.65–2.75 V). Substitution may cause out-of-spec regulation in precision circuits; also, the C-series has higher leakage (50 µA vs. 20 µA) and different thermal derating curves.

Is the SOD80C package compatible with standard reflow soldering profiles?

Yes - Nexperia specifies compatibility with JEDEC J-STD-020D reflow profiles. The SOD80C footprint (2.30 mm × 4.30 mm solder lands) supports peak temperatures up to 260 °C for ≤30 seconds, with recommended preheat ramp rate ≤3 °C/s and time above liquidus 60–90 seconds.
