Product details
Overview
PZU884LS-B12-QYL from Nexperia is a 12 V ±2 % tolerance Zener voltage regulator diode in a leadless DFN1006BD-2 (SOD882BD) package, rated for 365 mW total power dissipation and qualified to AEC-Q101 for automotive use. It delivers hard breakdown knee behavior with low dynamic impedance (≤105 Ω at IZ = 5 mA), low leakage current (≤0.1 μA at VR = 10 V), and side-wettable flanks for reliable reflow soldering in space-constrained power rail regulation.
For engineers reviewing the PZU884LS-B12-QYL datasheet, PZU884LS-B12-QYL pinout, PZU884LS-B12-QYL application, or PZU884LS-B12-QYL equivalent, key selection criteria include its 12 V nominal Zener voltage with ±2 % tolerance, 105 Ω typical differential resistance at 5 mA, AEC-Q101 qualification, ultra-small 1.0 mm × 0.6 mm footprint, and suitability for low-power voltage reference and overvoltage clamping in automotive ECUs and sensor interfaces.
Technical Context
This Zener diode operates in reverse-bias breakdown mode to maintain stable 12 V regulation across load and line variations. Its design emphasizes low dynamic impedance (105 Ω typ. at IZ = 5 mA) and tight voltage tolerance (±2 %) to minimize output deviation under varying current conditions.
The device features a hard breakdown knee and low leakage current (≤0.1 μA at VR = 10 V), enabling precise voltage clamping in low-current bias networks. Its side-wettable flanks support automated optical inspection (AOI) of solder joints on high-reliability automotive PCBs.
