Product details
Overview
PZU884LS-B3V9-QYL from Nexperia is a leadless SOD882BD (DFN1006BD-2) Zener voltage regulator diode with nominal 3.9 V breakdown voltage, ±2 % tolerance, 90 Ω differential resistance at IZ = 5 mA, and 3 μA reverse leakage at VR = 3.7 V - designed for precision voltage reference and clamping in space-constrained automotive power rails.
For engineers reviewing the PZU884LS-B3V9-QYL datasheet, PZU884LS-B3V9-QYL pinout, PZU884LS-B3V9-QYL application, or PZU884LS-B3V9-QYL equivalent, this device delivers AEC-Q101-qualified stability in ultra-small 1.0 mm × 0.6 mm packages with side-wettable flanks for automated optical inspection and high-yield reflow soldering.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain stable voltage regulation across varying load currents and temperature conditions. Its hard breakdown knee and low dynamic impedance ensure minimal voltage deviation under transient current steps up to 200 mA forward/40 W non-repetitive surge.
Designed for automotive-grade reliability, it features intentional low leakage (3 μA max at VR = 3.7 V) and a temperature coefficient of −3.5 mV/K at IZ = 5 mA - enabling predictable drift compensation in 12 V system monitoring circuits and ECU input protection networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener voltage VZ | 3.7 V to 4.1 V at IZ = 5 mA - defines tight regulation window for 3.3 V logic rail stabilization |
| Differential resistance rdif | 90 Ω max at IZ = 5 mA - ensures <±20 mV output shift under ±1.8 mA load variation |
| Reverse leakage IR | 3 μA max at VR = 3.7 V - minimizes quiescent current draw in always-on vehicle modules |
| Forward voltage VF | 0.9 V max at IF = 10 mA - enables low-loss polarity protection in bidirectional clamp configurations |
| Total power dissipation Ptot | 365 mW on FR4 PCB - supports continuous operation in ambient temperatures up to +105 °C |
| Junction temperature Tj | −55 °C to +150 °C - meets under-hood thermal requirements per AEC-Q101 stress testing |
| Package | DFN1006BD-2 (SOD882BD), 1.0 mm × 0.6 mm × 0.47 mm - enables 0201-class board area with side-wettable flanks for AOI |
Pinout & Package

FAQ
What is the maximum non-repetitive peak reverse power the PZU884LS-B3V9-QYL can handle?
The device supports up to 40 W non-repetitive peak reverse power dissipation for pulse durations of 100 μs at Tj = 25 °C prior to surge. This rating enables robust protection against ISO 7637-2 load-dump transients in 12 V automotive systems without thermal runaway.
How does the side-wettable flank (SWF) feature improve manufacturing yield?
Side-wettable flanks allow automated optical inspection (AOI) systems to verify solder fillet formation on both lateral edges of the DFN1006BD-2 package. This eliminates blind spots inherent in bottom-only inspection of traditional QFNs, increasing first-pass yield by >12% in high-volume automotive PCB assembly.
Is the PZU884LS-B3V9-QYL suitable for use in 48 V mild-hybrid vehicle architectures?
No - its 4.1 V maximum Zener voltage and 365 mW steady-state power rating are optimized for 12 V system nodes (e.g., ECU sensor inputs, infotainment rails). For 48 V applications, Nexperia's PZU12V0LS-Q series with 12 V VZ and enhanced surge capability is recommended.
What is the significance of the 'QYL' suffix in the part number?
The 'QYL' suffix denotes tape-and-reel packaging per EIA-481 standard, with 10,000 units per reel and moisture sensitivity level (MSL) 1 - indicating unlimited floor life at ≤30 °C/60% RH and compatibility with standard SMT reflow profiles without baking.
