Product details
Overview
PZU884LS-B18-QYL from Nexperia is a ±2 % tolerance Zener voltage regulator diode with nominal 18 V breakdown voltage, housed in an ultra-small DFN1006BD-2 (SOD882BD) package featuring side-wettable flanks for automated optical inspection. It delivers 13 Ω differential resistance at IZ = 5 mA, −0.05 mV/K temperature coefficient, and 93 pF capacitance at 1 MHz, enabling precision voltage reference and overvoltage protection in space-constrained automotive power rails.
For engineers reviewing the PZU884LS-B18-QYL datasheet, PZU884LS-B18-QYL pinout, PZU884LS-B18-QYL application, or PZU884LS-B18-QYL equivalent, this device supports AEC-Q101-compliant designs requiring stable low-leakage regulation at 18 V with minimal thermal drift and high surge immunity up to 40 W non-repetitive peak reverse power.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain a stable 18 V reference across load variations, with hard breakdown knee and very low leakage current optimized for low-noise analog and power-supply feedback paths. Its differential resistance of 13 Ω at 5 mA ensures tight regulation under dynamic current conditions.
The device uses silicon planar technology with side-wettable flanks for reliable reflow solder joint inspection, and its negative temperature coefficient (−0.05 mV/K) enables predictable thermal behavior in ambient ranges from −55 °C to +150 °C. Junction-to-ambient thermal resistance is 340 K/W on standard FR4 PCBs.

FAQ
What is the maximum reverse voltage this Zener can regulate continuously?
The PZU884LS-B18-QYL is rated for continuous operation at its nominal Zener voltage of 18 V with ±2 % tolerance. Its absolute maximum reverse voltage is not specified separately; instead, it is governed by the limiting value of total power dissipation (365 mW at 25 °C ambient). At 18 V, this corresponds to a maximum continuous Zener current of approximately 20.3 mA under ideal thermal conditions.
Does this part require a series current-limiting resistor in typical applications?
Yes - like all Zener diodes, PZU884LS-B18-QYL requires an external series resistor to limit current through the device and prevent thermal runaway. The resistor value must be selected to ensure Zener current stays within the recommended operating range (typically 1–20 mA) while accommodating worst-case input voltage and load variations, especially under high-temperature conditions where power derating applies.
How does the side-wettable flank feature impact assembly yield?
The side-wettable flanks on the DFN1006BD-2 package allow automated optical inspection (AOI) systems to verify solder joint quality by imaging solder fillet formation along the package edges. This eliminates reliance on X-ray inspection for hidden-joint verification, reducing test time and cost while increasing defect detection rates for head-in-pillow and insufficient-solder defects in high-volume SMT lines.
Is the −0.05 mV/K temperature coefficient measured at full rated current?
No - the −0.05 mV/K temperature coefficient for PZU884LS-B18-QYL is specified at IZ = 5 mA and Tj = 25 °C to 150 °C, per Table 8 in the datasheet. Coefficient magnitude increases slightly at lower currents (e.g., 0.5 mA), but remains negative across the full operating range, ensuring predictable and monotonic voltage drift with temperature rise.
