Nexperia USA Inc. BZV55-C2V7,115

Overview

BZV55-C2V7,115 from Nexperia is a low-power Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, providing a nominal 2.7 V regulation voltage with ±5 % tolerance at 5 mA test current, 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 paths, and overvoltage protection circuits for microcontroller peripherals.

For engineers reviewing the BZV55-C2V7,115 datasheet, BZV55-C2V7,115 pinout, BZV55-C2V7,115 application, or BZV55-C2V7,115 equivalent, key selection criteria include Zener voltage accuracy at low test current (IZ = 5 mA), thermal stability across operating temperature, reverse leakage at VR = 1 V (≤20 µA), and compatibility with reflow soldering on standard PCBs using the SOD80C footprint.

Technical Context

This Zener diode operates in reverse breakdown to maintain a stable DC reference voltage under varying load and temperature conditions. Its −2.0 mV/K temperature coefficient indicates moderate negative drift, requiring compensation in precision references, while its 300 Ω typical differential resistance defines output impedance and load regulation error.

The device is rated for 400 mW total power dissipation at ambient ≤50 °C and supports non-repetitive peak reverse power up to 40 W for 100 µs pulses. Its 0.9 V forward voltage at 10 mA enables use as a low-drop clamp in bidirectional protection schemes.

FAQ

What is the maximum continuous power dissipation for BZV55-C2V7,115?

The BZV55-C2V7,115 has a maximum total power dissipation of 400 mW at ambient temperatures ≤50 °C when mounted on a ceramic substrate (10 × 10 × 0.6 mm). At higher ambient temperatures or on standard FR4, derating applies per its thermal resistance of 380 K/W junction-to-ambient.

How does the −2.0 mV/K temperature coefficient affect circuit performance?

A −2.0 mV/K coefficient means the Zener voltage decreases by approximately 2 mV per Kelvin rise in junction temperature. Over a 50 °C temperature range, this yields ~100 mV drift-requiring layout-level thermal isolation or calibration in precision references, but acceptable for non-critical biasing.

Can BZV55-C2V7,115 be used in bidirectional ESD protection?

No-it is a unidirectional Zener diode optimized for reverse-bias regulation. For bidirectional ESD protection, a dedicated TVS diode (e.g., PESD5V0S1BA) or back-to-back Zener pair is required; forward conduction is limited to 0.9 V at 10 mA and not rated for surge current.

Is the SOD80C package compatible with standard reflow profiles?

Yes-the SOD80C package is qualified for lead-free reflow soldering per JEDEC J-STD-020. Recommended profile includes peak temperature ≤260 °C for ≤10 seconds, with ramp rates and soak times aligned to IPC-7095 guidelines for small glass-body SMDs.
