Nexperia USA Inc. BZV55-C4V7,115

Overview

BZV55-C4V7,115 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 4.7 V nominal Zener voltage at 5 mA, with 500 mW total power dissipation and 425 Ω typical differential resistance at I_Z = 5 mA. It serves as a precision low-power reference or clamp in analog signal conditioning, power supply feedback loops, and overvoltage protection circuits.

For engineers reviewing the BZV55-C4V7,115 datasheet, BZV55-C4V7,115 pinout, BZV55-C4V7,115 application, or BZV55-C4V7,115 equivalent, key selection criteria include its ±5 % voltage tolerance, 4.7 V regulation point, SOD80C thermal performance (R_th(j-a) = 380 K/W), and non-repetitive surge capability of 40 W at 100 µs.

Technical Context

This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under varying current loads. Its temperature coefficient of −1.4 mV/K at I_Z = 5 mA indicates moderate negative drift, requiring thermal compensation in high-accuracy references. The 300 pF diode capacitance at 1 MHz and 0 V bias supports use in low-frequency regulation but limits RF applications.

Designed for DC or low-frequency stabilization, it delivers regulated output only when reverse-biased above its 4.7 V threshold with sufficient current (≥1 mA). Its 425 Ω differential resistance implies ~2.1 mV change per 5 µA current shift - critical for load regulation analysis in feedback networks.

FAQ

What is the maximum continuous reverse current for reliable operation?

The BZV55-C4V7,115 is rated for 250 mA maximum forward current, but its safe continuous reverse (Zener) current is limited by power dissipation: at 25 °C ambient, I_Z must stay ≤106 mA to remain within 500 mW (P = V_Z × I_Z). Derating applies above 50 °C ambient per the 380 K/W thermal resistance specification.

How does the −1.4 mV/K temperature coefficient affect circuit accuracy?

A −1.4 mV/K coefficient means the Zener voltage decreases by 1.4 mV for every 1 K rise in junction temperature. Over a 50 K rise (e.g., 25 °C to 75 °C), this causes ~70 mV drop - approximately 1.5 % of 4.7 V. Designs requiring <0.5 % stability must include thermal compensation or operate within narrow ambient ranges.

Can this diode be used in AC signal clipping applications?

Yes - the BZV55-C4V7,115 can clip AC signals when back-to-back configured with another diode or used with series resistance. Its 0.9 V forward voltage and 4.7 V reverse breakdown provide asymmetric clipping thresholds. However, its 300 pF capacitance limits usable frequency to below ~1 MHz, and power handling requires limiting peak current to avoid exceeding 40 W surge or 500 mW average ratings.

Is the SOD80C package compatible with standard reflow soldering profiles?

Yes - Nexperia specifies the SOD80C package for lead-free reflow soldering per JEDEC J-STD-020. The recommended profile includes peak temperature ≤260 °C for ≤10 seconds, with ramp rates ≤3 °C/s pre- and post-peak. Figure 7 in the datasheet provides the exact footprint layout, confirming compatibility with standard 4 mm pitch tape-and-reel handling and automated placement.
