Product details
Overview
PZU884LS-C20-QYL from Nexperia is a ±5 % tolerance Zener voltage regulator diode with nominal 20 V breakdown voltage, ultra-low leakage current (≤0.05 μA at VR = 15 V), differential resistance of 100 Ω at IZ = 5 mA, and AEC-Q101 qualification for automotive power rail stabilization in engine control units and ADAS sensor modules.
For engineers reviewing the PZU884LS-C20-QYL datasheet, PZU884LS-C20-QYL pinout, PZU884LS-C20-QYL application, or PZU884LS-C20-QYL equivalent, this page delivers verified Zener parameters, side-wettable DFN1006BD-2 package handling guidance, automotive-grade thermal derating curves, and direct substitution options with documented voltage tolerance and leakage trade-offs.
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 ensures sharp regulation onset, while intentional low leakage (<0.05 μA) minimizes standby current draw in always-on automotive subsystems.
The device uses silicon planar epitaxial construction with optimized doping profiles for predictable temperature coefficient behavior (SZ = +15 mV/K at 20 V) and low dynamic impedance across its 5 mA operating point. It is rated for 365 mW continuous dissipation on FR4 PCB and withstands 40 W non-repetitive surge pulses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 18.86 V to 21.08 V at IZ = 5 mA - defines regulated output range for precision 20 V rail clamping |
| Differential Resistance (rdif) | 100 Ω max at IZ = 5 mA - determines output impedance and load regulation error |
| Reverse Leakage (IR) | ≤0.05 μA at VR = 15 V - enables ultra-low quiescent current in battery-backed circuits |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - supports bidirectional ESD protection when used in back-to-back configuration |
| Power Dissipation (Ptot) | 365 mW on FR4 PCB - sets maximum continuous DC power handling without heatsinking |
| Junction Temperature (Tj) | −55 °C to +150 °C - supports operation in under-hood automotive environments |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test standard for discrete semiconductors |
Pinout & Package
Package: DFN1006BD-2 (SOD882BD), leadless ultra-small surface-mount plastic package with side-wettable flanks; dimensions 1.0 mm × 0.6 mm × 0.47 mm, 0.65 mm pitch, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated voltage node; polarity must be observed for correct breakdown conduction |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms reverse-biased junction with cathode |
Key Features
| Feature | Design Value |
|---|---|
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints on DFN packages during reflow assembly |
| ±5 % voltage tolerance | Supports cost-sensitive automotive applications where tighter tolerance is not required for rail clamping |
| Hard breakdown knee | Ensures rapid transition into regulation, minimizing voltage overshoot during transient events |
| Low thermal resistance (Rth(j-a)) | 340 K/W - allows efficient heat dissipation on standard FR4 without thermal vias or copper pours |
| Optimized for fast switching | Minor intentional leakage rise improves noise suppression in high-frequency power supply feedback paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C20,115 | ±5 % tolerance, SOT23 package, 350 mW Ptot, higher rdif (150 Ω), no AEC-Q101 qualification | Non-automotive industrial controls only; lacks side-wettable flanks and automotive reliability validation | Select for cost-sensitive consumer designs where AOI and automotive qualification are unnecessary |
| MMSZ5248B-TP | ±5 % tolerance, SOD-123 package, 500 mW Ptot, rdif = 30 Ω, Tj = 150 °C, no AEC-Q101 | Higher power handling but larger footprint; unsuitable for space-constrained automotive PCBs | Choose when higher continuous power (>365 mW) is needed and board area permits SOD-123 placement |
Compared with PZU884LS-C20-QYL, BZX84-C20 offers lower cost but sacrifices automotive qualification and AOI compatibility, while MMSZ5248B provides superior power rating and lower impedance but requires 3× more PCB area and lacks AEC-Q101 validation.

FAQ
What is the maximum continuous reverse current the PZU884LS-C20-QYL can sustain at 25 °C?
The device supports up to 200 mA forward current, but for Zener operation, the maximum continuous reverse current is limited by power dissipation: at 20 V, Imax = 365 mW ÷ 20 V ≈ 18.25 mA. Exceeding this risks thermal runaway unless board-level cooling is enhanced.
Does the PZU884LS-C20-QYL require external series resistance in typical shunt regulation circuits?
Yes - a series current-limiting resistor is mandatory to set operating current within the 5 mA to 18.25 mA range. For example, with 24 V input and 20 V output, a 220 Ω resistor limits current to ~18.2 mA, ensuring stable regulation without exceeding Ptot.
How does the side-wettable flank design impact reflow soldering yield?
The side-wettable flanks allow solder to wick visibly up the package edge during reflow, enabling automated optical inspection (AOI) to verify fillet formation and detect voids or insufficient solder - critical for zero-defect automotive manufacturing.
Can PZU884LS-C20-QYL be used in parallel for higher power handling?
No - Zener diodes exhibit negative temperature coefficients below ~5 V and positive above, causing current hogging when paralleled. Even within the same batch, mismatched VZ and rdif values lead to unequal current sharing and potential thermal failure.
