Product details
Overview
PZU884LS-B20-QYL from Nexperia is a 20 V ±2 % tolerance Zener voltage regulator diode in a DFN1006BD-2 (SOD882BD) leadless SMD package with side-wettable flanks, rated for 365 mW total power dissipation at 25 °C, 150 °C max junction temperature, and qualified to AEC-Q101 for automotive power rail stabilization and ECU reference voltage regulation.
For engineers reviewing the PZU884LS-B20-QYL datasheet, PZU884LS-B20-QYL pinout, PZU884LS-B20-QYL application, or PZU884LS-B20-QYL equivalent, this device offers low dynamic impedance (100 Ω typical at IZ = 5 mA), hard breakdown knee, and <0.05 μA reverse leakage at VR = 15 V - critical for precision biasing in engine control modules and ADAS sensor interfaces.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable 20 V reference under varying load and temperature conditions. Its differential resistance of 100 Ω (typ. at 5 mA) and temperature coefficient of +15 mV/K (at 20 V) enable predictable voltage regulation across −55 °C to +150 °C ambient range.
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 in automotive ECUs. Thermal resistance from junction to ambient is 340 K/W on standard FR4 with single-sided 70 μm copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 20 V nominal, ±2 % tolerance (19.6 V to 20.4 V) - ensures tight reference accuracy for analog sensing circuits |
| Differential Resistance (rdif) | 100 Ω typical at IZ = 5 mA - minimizes output voltage variation under load current changes |
| Reverse Leakage (IR) | <0.05 μA at VR = 15 V - preserves low-power standby integrity in always-on vehicle networks |
| Total Power Dissipation (Ptot) | 365 mW at Tamb = 25 °C on FR4 - defines maximum continuous DC power handling in standard PCB mounting |
| Junction Temperature (Tj) | −55 °C to +150 °C - enables operation in under-hood environments without derating below −40 °C |
| AEC-Q101 Qualified | Qualified per Stress Test Qualification for Discrete Semiconductors - meets automotive reliability requirements for production ECUs |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; reverse-biased terminal where Zener breakdown occurs |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path for regulation |
Key Features
| Feature | Design Value |
|---|---|
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints on bottom-terminated 2-terminal packages |
| Hard breakdown knee | Sharp, well-defined Zener transition at 20 V improves regulation stability during transient load steps |
| Low leakage current | <0.05 μA at 75 % of VZ reduces quiescent current drain in battery-backed systems |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, HTRB, and ESD testing per AEC standard |
Applications

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-C20,215 | ±5 % tolerance, SOT23 package (3.0 mm × 1.4 mm), higher rdif (120 Ω typ.), no AEC-Q101 qualification | Non-automotive consumer electronics only; unsuitable for under-hood deployment due to thermal and reliability limits | Select only for cost-sensitive, non-automotive designs where ±5 % tolerance and larger footprint are acceptable |
| MMSZ5248B-TP | ±5 % tolerance, SOD-123 package (3.7 mm × 1.6 mm), 500 mW Ptot, but unqualified per AEC-Q101 | Higher power handling but lacks automotive qualification and side-wettable flanks for AOI | Prefer only if board space permits larger package and AEC compliance is not required |
Compared with BZX84-C20,215 and MMSZ5248B-TP, PZU884LS-B20-QYL delivers tighter ±2 % tolerance, automotive-grade reliability, and AOI-compatible packaging - making it the sole choice for space-constrained, safety-critical automotive voltage references.

FAQ
What is the maximum non-repetitive peak reverse power dissipation for PZU884LS-B20-QYL?
The device supports 40 W non-repetitive peak reverse power dissipation at tp = 100 μs (square wave), with Tj = 25 °C prior to surge. This rating enables robust protection against load-dump transients in 12 V/24 V automotive systems without permanent degradation.
Does PZU884LS-B20-QYL require a heatsink in standard PCB mounting?
No heatsink is required. With Rth(j-a) = 340 K/W on FR4 (single-sided 70 μm Cu), the device remains within 150 °C Tj limit at ≤365 mW continuous dissipation. Derating begins above 25 °C ambient, per the thermal curve in Figure 9 of the datasheet.
How is polarity identified on the PZU884LS-B20-QYL package?
A laser-marked bar on the top surface indicates the cathode (Pin 1). The anode (Pin 2) is the opposite terminal. This marking aligns with the simplified outline in Table 2 and Figure 9 of the datasheet, and is visible under 20× magnification for post-solder verification.
Can PZU884LS-B20-QYL be used in place of a 20 V Zener with ±5 % tolerance?
Yes, but with design impact: its ±2 % tolerance improves reference accuracy by 2.5× versus ±5 % parts, reducing system calibration burden. However, forward voltage remains identical (≤0.9 V at 10 mA), so existing bias network calculations remain valid.
