Product details
Overview
PZU884LS-C43-Q from Nexperia is a Zener voltage regulator diode in the PZU884LS-Q series, designed for precision voltage reference and regulation in space-constrained automotive and industrial circuits. It delivers a nominal 43 V Zener voltage with ±5 % tolerance, 375 Ω differential resistance at IZ = 2 mA, and 0.05 μA reverse current at VR = 30.1 V - enabling stable clamping in ECU power rail supervision.
For engineers reviewing the PZU884LS-C43-Q datasheet, PZU884LS-C43-Q pinout, PZU884LS-C43-Q application, or PZU884LS-C43-Q equivalent, this device is evaluated for AEC-Q101-compliant overvoltage protection, low-leakage biasing, and fast-switching noise suppression in 12 V/24 V automotive subsystems.
Technical Context
This Zener diode operates in reverse breakdown mode with hard knee characteristics optimized for low-current regulation (IZ = 2 mA) and exhibits intentional minor leakage rise to improve switching speed and reduce high-frequency noise per AN90031. Its thermal resistance Rth(j-a) is 340 K/W on standard FR4, limiting continuous dissipation to 365 mW at Tamb = 25 °C.
The DFN1006BD-2 package features side-wettable flanks for automated optical solder-joint inspection, and its 1.0 mm × 0.6 mm footprint supports high-density PCB layouts. Junction temperature is rated up to 150 °C, supporting operation in under-hood automotive environments.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C43,115 | Same 43 V nominal, ±5 % tolerance, but SOT23 package (larger footprint, no SWF) | Lacks AEC-Q101 qualification and side-wettable flanks; unsuitable for automated AOI in automotive production | Select when legacy SOT23 layout reuse is required and AEC-Q101 is not mandated |
| MMSZ43ET1G | 43 V, ±5 %, SOD-123 package; higher rdif (500 Ω typ), higher leakage (1.0 μA at 34 V) | Higher dynamic impedance degrades regulation under fast load changes; higher leakage increases quiescent current | Select only for cost-sensitive non-automotive applications where 365 mW dissipation margin is sufficient |
Compared with BZX84-C43,115 and MMSZ43ET1G, PZU884LS-C43-Q provides superior automotive manufacturability via SWF, tighter thermal performance (340 K/W vs. >400 K/W), and lower leakage - making it the preferred choice for new AEC-Q101 designs requiring compact, inspectable, low-power Zener regulation.

FAQ
What is the maximum continuous forward current for PZU884LS-C43-Q?
The device is a Zener diode intended for reverse-bias operation; its absolute maximum forward current is 200 mA per Table 5. However, forward conduction is not a functional operating mode - the diode is rated for reverse breakdown regulation at 43 V, with forward voltage limited to 0.9 V at 10 mA per Table 1.
Does PZU884LS-C43-Q require a series resistor in typical Zener regulation circuits?
Yes - a current-limiting resistor is mandatory to set the Zener operating current (IZ) within 2 mA (typical test condition) and below the 365 mW power limit. For a 48 V supply regulating at 43 V, a minimum 2.5 kΩ resistor ensures IZ ≤ 2 mA and Ptot ≤ 365 mW at ambient temperature.
How does the "intentional minor rise of leakage current" benefit circuit performance?
Per AN90031, this controlled leakage increase reduces minority-carrier storage time, enabling faster turn-off during transient suppression and lowering high-frequency noise generation in bias networks - particularly valuable in ADAS sensor references and CAN transceiver protection paths.
Can PZU884LS-C43-Q be used in place of PZU884LS-B43-Q?
No - PZU884LS-B43-Q has ±2 % tolerance (42.1 V–43.9 V), while PZU884LS-C43-Q has ~±5 % tolerance (40.0 V–46.0 V). Their differential resistance also differs: B43-Q is 350 Ω max at IZ = 2 mA, versus 375 Ω for C43-Q. Substitution requires revalidation of regulation accuracy and thermal margin.
