Product details
Overview
PZU884LS-C18-Q from Nexperia is a leadless SOD882BD (DFN1006BD-2) Zener voltage regulator diode with nominal 18 V breakdown voltage, ±5 % tolerance, 80 Ω differential resistance at IZ = 5 mA, and AEC-Q101 qualification for automotive use. It delivers stable reference voltage in compact power management circuits where space-constrained PCB layout and low leakage are critical.
For engineers reviewing the PZU884LS-C18-Q datasheet, PZU884LS-C18-Q pinout, PZU884LS-C18-Q application, or PZU884LS-C18-Q equivalent, key selection factors include its side-wettable flank package for automated optical inspection, 13 μA reverse current at VR = 14.4 V, −0.05 mV/K temperature coefficient, and 365 mW steady-state power dissipation on standard FR4.
Technical Context
This Zener diode operates in reverse breakdown to maintain precise DC voltage regulation across varying load and line conditions. Its design targets low-current stability (IZ = 5 mA typical), hard breakdown knee, and minimal thermal drift - enabled by optimized silicon doping and DFN1006BD-2 thermal path geometry.
The device exhibits intentional minor leakage rise relative to lower-voltage variants (e.g., C2V4–C10 series), balancing fast transient response and noise reduction per AN90031. Junction-to-ambient thermal resistance is 340 K/W under standard mounting, supporting reliable operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (nominal) | 18 V - Stable regulation point for 15–20 V supply rail conditioning |
| Tolerance | ±5 % - Matches cost-sensitive automotive sensor biasing requirements |
| rdif | 80 Ω at IZ = 5 mA - Low dynamic impedance ensures <100 mV output variation over 1–10 mA load range |
| IR | 13 μA at VR = 14.4 V - Enables low-quiescent-power voltage reference in always-on modules |
| Ptot | 365 mW - Supports continuous regulation on 70 μm single-sided FR4 without heatsinking |
| SZ | −0.05 mV/K - Near-zero temperature coefficient minimizes drift over −40 °C to +125 °C ambient |
| Cd | 93 pF at f = 1 MHz - Limits high-frequency noise coupling in analog front-end protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C18 | SC-70 package (2.2 mm × 1.35 mm), higher rdif (100 Ω), no AEC-Q101 qualification | Larger footprint; unsuitable for automotive under-hood environments requiring extended temperature reliability | Select when cost is primary constraint and AEC-Q101 compliance is not required |
| MMSZ5245B | SOD-123 package (3.7 mm × 1.6 mm), ±5 % tolerance, 100 Ω rdif, 500 mW Ptot | Higher power handling but incompatible with fine-pitch automated assembly due to lack of side-wettable flanks | Select when higher steady-state power (>365 mW) is needed and AOI capability is not mandatory |
Compared with BZX84-C18 and MMSZ5245B, PZU884LS-C18-Q provides superior manufacturability via side-wettable flanks, tighter thermal performance on FR4, and guaranteed automotive-grade reliability - making it optimal for space-constrained, high-volume automotive electronics where solder joint quality and long-term parametric stability are non-negotiable.

FAQ
What is the maximum continuous reverse current the PZU884LS-C18-Q can sustain without degradation?
The device is rated for a maximum forward current of 200 mA, but as a Zener regulator, its continuous reverse (Zener) current is limited by thermal dissipation. At 25 °C ambient on standard FR4, sustained IZ must remain ≤10 mA to stay within the 365 mW total power limit and avoid exceeding 150 °C junction temperature. Derating is required above 25 °C per the 340 K/W thermal resistance.
Does the PZU884LS-C18-Q support reflow soldering with standard lead-free profiles?
Yes - the DFN1006BD-2 package is qualified for IPC/JEDEC J-STD-020D-compliant lead-free reflow. Nexperia specifies a peak temperature of 260 °C for 30 seconds max, with ramp rates ≤3 °C/s pre- and post-peak. The side-wettable flanks ensure reliable solder fillet formation and AOI compatibility under these conditions.
How does the temperature coefficient of −0.05 mV/K impact regulation accuracy over temperature?
At 18 V nominal VZ, this coefficient yields only −0.9 mV/°C drift - translating to ±10.8 mV total variation over a −40 °C to +125 °C junction range. This enables sub-0.1 % regulation stability without external compensation, critical for precision analog monitoring in automotive ECUs.
Can PZU884LS-C18-Q be used in parallel for higher power handling?
No - Zener diodes exhibit negative temperature coefficients and mismatched VZ tolerances, causing current hogging when paralleled. Even with matched units, thermal runaway risk remains high. For >365 mW dissipation, use a single higher-rated Zener or an active shunt regulator topology instead.
