Product details

Overview

BZV90-C3V0,115 from Nexperia is a medium-power Zener voltage regulator diode in SOT223 package, designed for precision DC voltage reference and regulation at 3.0 V nominal working voltage (2.8–3.2 V), with ±5% tolerance, 80–95 Ω differential resistance at 5 mA test current, and 1500 mW total power dissipation. It serves in low-voltage power supply stabilization circuits for microcontroller I/O protection and sensor biasing.

For engineers reviewing the BZV90-C3V0,115 datasheet, BZV90-C3V0,115 pinout, BZV90-C3V0,115 application, or BZV90-C3V0,115 equivalent, key selection criteria include Zener voltage accuracy at 5 mA, thermal resistance (83.3 K/W), non-repetitive peak reverse power (40 W), junction temperature limit (150 °C), and SOT223 thermal pad layout compatibility.

Technical Context

This Zener diode operates in reverse breakdown mode with tightly controlled voltage regulation across its E24-standardized 3.0 V nominal point. Its differential resistance of ≤95 Ω at 5 mA ensures stable regulation under varying load currents, while the negative temperature coefficient (−3.5 to −2.1 mV/K) enables predictable drift behavior in ambient-temperature-sensitive designs.

The device uses a silicon planar epitaxial construction optimized for SOT223's copper-clad FR4 mounting (2 cm² area), delivering 1500 mW continuous dissipation and 40 W non-repetitive surge capability (100 μs square wave). Its 450 pF capacitance at 0 V reverse bias supports moderate-speed regulation without significant signal coupling.

FAQ

What is the maximum continuous forward current rating for BZV90-C3V0,115?

The maximum continuous forward current is 400 mA at T_amb = 25 °C. This rating applies only during forward conduction (e.g., during power-up sequencing or fault conditions), not during normal Zener regulation, which occurs in reverse bias. Exceeding this value risks metallization failure or bond wire overheating.

How does the temperature coefficient affect regulation stability across operating temperature?

The BZV90-C3V0,115 exhibits a typical temperature coefficient of −2.1 mV/K, meaning its Zener voltage decreases by approximately 2.1 mV per Kelvin rise in junction temperature. At 125 °C junction temperature, this results in ~−210 mV shift from 25 °C baseline-within the 2.8–3.2 V specification band and usable in compensated reference designs.

Can BZV90-C3V0,115 be used in parallel for higher power handling?

No-parallel connection is not recommended due to mismatched Zener voltages and thermal runaway risk. Even small V_Z differences cause current hogging in one device. For higher power, use a single larger-package Zener or a dedicated shunt regulator IC with thermal foldback.

What is the significance of the "115" suffix in the part number?

The "115" suffix denotes the specific tape-and-reel packaging variant per JEDEC standard: 1000 pieces per reel, 12 mm tape width, and EIA-481-D compliant embossed carrier tape-ensuring compatibility with automated SMT placement equipment and standard feeder settings.
