Product details
Overview
PZU884LS-B22-QYL from Nexperia is a ±2 % tolerance Zener voltage regulator diode with nominal 22 V breakdown voltage, optimized for low-leakage precision regulation in automotive and industrial power rails. It features 100 Ω differential resistance at 5 mA, 17 μA reverse current at rated voltage, and operates up to 150 °C junction temperature in the DFN1006BD-2 (SOD882BD) package.
For engineers reviewing the PZU884LS-B22-QYL datasheet, PZU884LS-B22-QYL pinout, PZU884LS-B22-QYL application, or PZU884LS-B22-QYL equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (340 K/W), side-wettable flank soldering compatibility, and automotive-grade reliability data - all confirmed from Nexperia's Rev. 4 product data sheet dated 16 August 2024.
Technical Context
This Zener diode belongs to the PZU884LS-Q series' B-tolerance subgroup (±2 %), engineered for stable voltage reference with hard breakdown knee and very low leakage current - critical for low-power sensor biasing and feedback loop accuracy. Its 22 V nominal Zener voltage falls within the 20–24 V range where temperature coefficient is +16.4 mV/K at 5 mA, enabling predictable drift compensation.
The device uses a planar silicon process with side-wettable flanks on a DFN1006BD-2 footprint (1.0 mm × 0.6 mm × 0.47 mm), supporting automated optical inspection (AOI) and high-yield reflow soldering per IPC-7351B. Junction-to-ambient thermal resistance of 340 K/W is measured on FR4 with single-sided 70 μm copper, defining its derating envelope in compact PCB layouts.

FAQ
What is the maximum reverse current specification for PZU884LS-B22-QYL at its rated Zener voltage?
The maximum reverse current (IR) is 17 μA at VR = 17.6 V, measured per Table 8 of the Rev. 4 datasheet. This value reflects the device's low-leakage performance in the B-series subgroup, critical for maintaining accuracy in low-power bias networks and extending battery life in always-on applications.
Does PZU884LS-B22-QYL support automated optical inspection (AOI) during PCB assembly?
Yes - the DFN1006BD-2 package features side-wettable flanks, allowing AOI systems to verify solder joint integrity without requiring X-ray inspection. This capability is explicitly cited in Section 2 ("Features and benefits") and confirmed in the package outline (Figure 9) of the official datasheet.
How does the temperature coefficient of PZU884LS-B22-QYL affect its regulation accuracy across operating temperature?
At 22 V nominal Zener voltage, the temperature coefficient is +16.4 mV/K at IZ = 5 mA (Table 8). This means output voltage increases by ~16.4 mV per °C rise - a predictable linear drift that can be compensated in closed-loop designs or accounted for in reference buffer calibration routines.
Can PZU884LS-B22-QYL replace older Zener diodes like BZX84-C22 in existing designs?
Direct replacement requires layout revision due to the DFN1006BD-2 (1.0 mm × 0.6 mm) vs. SOT23 (3.0 mm × 1.4 mm) footprint difference. Electrical substitution is viable only if ±2 % tolerance, 17 μA leakage, and AEC-Q101 qualification are required - otherwise, thermal and space advantages may not offset redesign effort.
