Product details
Overview
PZU5.6BA,115 from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, designed for precision voltage reference and overvoltage protection in low-power analog circuits. It delivers 5.6 V nominal Zener voltage at 5 mA, with 100 Ω maximum differential resistance, 1000 nA reverse current at 0.5 mA, and operates across –55 °C to +150 °C ambient temperature.
For engineers reviewing the PZU5.6BA,115 datasheet, PZU5.6BA,115 pinout, PZU5.6BA,115 application, or PZU5.6BA,115 equivalent, key selection criteria include Zener voltage tolerance, dynamic impedance at regulation current, thermal resistance (Rth(j-a) = 390 K/W), junction temperature limit (150 °C), and SOD323 footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable DC voltage under varying load and supply conditions. Its hard breakdown knee and low leakage current support accurate voltage clamping in signal conditioning and power rail supervision circuits.
The device exhibits a positive temperature coefficient of +2.5 mV/K at 5 mA, enabling predictable drift compensation in temperature-sensitive references. Its 275 pF capacitance at 1 MHz and 0 V bias makes it suitable for low-frequency regulation but not RF bypass applications.
Key Specifications

The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B5V6 | Same 5.6 V nominal, ±5 % tolerance, but SOD323 package with 400 mW Ptot rating | Higher power dissipation supports higher continuous current in linear regulators | Select when >320 mW steady-state dissipation is required; verify thermal pad layout compatibility |

FAQ
What is the maximum continuous reverse current this Zener can handle?
The PZU5.6BA,115 has no specified maximum continuous reverse current, but its 320 mW total power dissipation limits continuous Zener current to approximately 57 mA at 5.6 V (P = V × I). Exceeding this risks thermal runaway due to its 390 K/W junction-to-ambient thermal resistance on standard FR4 PCB.
Does this part have automotive qualification?
No, the PZU5.6BA,115 is not automotive-qualified. Nexperia explicitly states in its legal disclaimers that unless the data sheet expressly declares automotive qualification, the product is unsuitable for automotive use. It lacks AEC-Q101 testing and is rated only for industrial temperature range (–55 °C to +150 °C) without automotive reliability validation.
How does the temperature coefficient affect regulation accuracy?
With a +2.5 mV/K temperature coefficient at 5 mA, the Zener voltage increases by 2.5 mV per degree Celsius rise in junction temperature. Over a 100 °C operating range (25 °C to 125 °C), this causes up to ±250 mV drift-requiring thermal management or compensation circuitry in precision reference designs.
Can this Zener be used in AC signal clipping applications?
Yes, but only for low-frequency signals (<100 kHz). Its 275 pF junction capacitance at 0 V bias introduces significant attenuation and phase shift above ~100 kHz. For AC clipping, ensure signal amplitude stays below the 5.92 V upper Zener limit and avoid sustained forward conduction beyond 1.1 V to prevent thermal stress.
