Nexperia USA Inc. BZV55-B3V3,115

Overview

BZV55-B3V3,115 from Nexperia is a low-power Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 3.3 V nominal regulation at 5 mA with ±2 % tolerance, 350 Ω typical differential resistance, and −2.4 mV/K temperature coefficient. It delivers stable reference voltage in low-current bias networks, power supply feedback paths, and overvoltage protection circuits for industrial sensors and microcontroller I/O conditioning.

For engineers reviewing the BZV55-B3V3,115 datasheet, BZV55-B3V3,115 pinout, BZV55-B3V3,115 application, or BZV55-B3V3,115 equivalent, key selection criteria include its 3.3 V ±2 % Zener voltage, 500 mW total power dissipation, 5 µA reverse leakage at VR = 1 V, 350 Ω differential resistance at IZ = 5 mA, and SOD80C thermal resistance of 300 K/W to solder point.

Technical Context

This device operates as a two-terminal shunt voltage reference, maintaining regulation by conducting reverse current when applied voltage exceeds its 3.3 V Zener breakdown threshold. Its low 350 Ω differential resistance ensures minimal output voltage variation under load changes up to 250 mA forward current rating.

The −2.4 mV/K temperature coefficient indicates predictable, linear drift over junction temperature (−65 °C to +200 °C), enabling stable performance in ambient-temperature-varying environments without external compensation. Its 450 pF capacitance at 1 MHz and 0 V reverse bias supports use in moderate-speed signal clamping applications.

FAQ

What is the maximum continuous reverse power dissipation for BZV55-B3V3,115?

The BZV55-B3V3,115 has a total power dissipation rating of 500 mW at solder point temperature ≤50 °C. This value is derated linearly above 50 °C at 4.2 mW/°C, reaching zero at 167 °C, per the datasheet's thermal characteristics table and limiting values section.

How does the −2.4 mV/K temperature coefficient affect regulation accuracy over temperature?

At I_Z = 5 mA, the −2.4 mV/K coefficient causes the Zener voltage to decrease by 2.4 mV per Kelvin rise in junction temperature. Over a −40 °C to +85 °C ambient range (assuming 25 °C baseline), this results in a total drift of approximately −267 mV, or −8.1 % of nominal 3.3 V - a predictable, linear offset that can be compensated in system calibration.

Can BZV55-B3V3,115 be used in forward-bias applications?

Yes - the device exhibits a forward voltage of ≤0.9 V at I_F = 10 mA, making it suitable for low-drop rectification or ESD clamping in bidirectional configurations. However, its primary design intent and characterization are for reverse-bias Zener regulation; forward conduction is secondary and not optimized for high-current switching.

What is the meaning of the "115" suffix in BZV55-B3V3,115?

The "115" suffix denotes the packing method: 10000-unit tape-and-reel packaging with 4 mm pitch, per Nexperia's ordering information table. It does not indicate revision, temperature grade, or electrical variant - all electrical specs are defined by the base part number BZV55-B3V3.
