Product details
Overview
PZU884LS-B43-QYL from Nexperia is a leadless SOD882BD (DFN1006BD-2) Zener voltage regulator diode with nominal 43 V breakdown voltage, ±2 % tolerance, 375 Ω differential resistance at IZ = 2 mA, and AEC-Q101 qualification for automotive use in power rail stabilization and overvoltage protection circuits.
For engineers reviewing the PZU884LS-B43-QYL datasheet, PZU884LS-B43-QYL pinout, PZU884LS-B43-QYL application, or PZU884LS-B43-QYL equivalent, this device delivers precise low-current regulation with side-wettable flanks for automated optical inspection and high-reliability solder joint verification in space-constrained automotive ECUs.
Technical Context
This Zener diode operates in reverse-bias breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its hard breakdown knee and low leakage current (≤0.05 μA at VR = 30 V) support accurate voltage clamping in low-power sensor interfaces and microcontroller reset circuits.
The device features intentional minor leakage optimization per AN90031 for fast switching and noise reduction in dynamic supply monitoring applications. Thermal resistance of 340 K/W (junction-to-ambient, FR4 PCB) enables reliable operation up to 150 °C junction temperature in engine control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 40.0 V to 46.0 V at IZ = 2 mA - defines clamping threshold for 12 V/24 V automotive supply rails |
| Differential Resistance rdif | 375 Ω max at IZ = 2 mA - ensures <±100 mV regulation shift across 1–3 mA load variation |
| Reverse Current IR | ≤0.05 μA at VR = 30 V - minimizes standby power loss in always-on vehicle networks |
| Total Power Dissipation Ptot | 365 mW - supports continuous operation on standard FR4 PCB without thermal derating below 70 °C ambient |
| Non-repetitive Peak Power PZSM | 40 W at tp = 100 μs - withstands transient surges per ISO 7637-2 Pulse 1/2b in automotive environments |
| Junction Temperature Tj | −55 °C to +150 °C - meets extended temperature requirements for under-hood electronics |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including HTGB, HTRB, and temperature cycling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C43 | ±5 % tolerance, 500 Ω rdif at 5 mA, SOT23 package (3.0 mm × 1.4 mm) | Larger footprint, higher dynamic impedance, no AEC-Q101 qualification | Select for cost-sensitive non-automotive industrial designs where space and automotive compliance are not required |
| MMSZ5257B | ±5 % tolerance, 130 Ω rdif at 20 mA, SOD-123 package (2.7 mm × 1.4 mm) | Higher test current shifts operating point; lacks side-wettable flanks and AEC-Q101 validation | Prefer only when higher power dissipation (500 mW) is needed and AOI inspection is not mandated |
Compared with BZX84-C43 and MMSZ5257B, PZU884LS-B43-QYL offers tighter tolerance, smaller size, automotive qualification, and process-optimized leakage-making it the sole choice for AEC-compliant compact Zener references requiring AOI-verified assembly.

FAQ
What is the maximum reverse voltage that PZU884LS-B43-QYL can safely clamp?
The device is rated for non-repetitive peak reverse power dissipation of 40 W at 100 μs pulse width, corresponding to a peak clamping voltage of approximately 46 V under surge conditions. Continuous reverse operation must remain within the 40.0–46.0 V Zener range at ≤2 mA DC current to avoid thermal runaway.
Does PZU884LS-B43-QYL require a series current-limiting resistor in typical applications?
Yes - a series resistor is mandatory to limit forward current during normal operation and prevent exceeding the 365 mW total power dissipation limit. For 12 V supply clamping, a minimum 1 kΩ resistor ensures safe operation at 2 mA Zener current while maintaining regulation accuracy.
How does the side-wettable flank design impact PCB assembly yield?
The side-wettable flanks enable automated optical inspection (AOI) of solder fillet formation on both lateral edges of the DFN1006BD-2 package, improving defect detection rate by >95 % compared to standard DFN packages and reducing field failure risk in automotive production lines.
Can PZU884LS-B43-QYL be used in place of PZU884LS-B43-Q without modification?
Yes - the "-QYL" suffix denotes tape-and-reel packaging with specific reel orientation and labeling per customer requirements; electrical, thermal, and mechanical specifications are identical to the base PZU884LS-B43-Q part, enabling drop-in replacement in existing designs.
