Product details
Overview
PZU884LS-C3V9-QYL from Nexperia is a leadless SOD882BD (DFN1006BD-2) Zener voltage regulator diode with nominal 3.9 V breakdown voltage, ±5 % tolerance, 90 Ω differential resistance at 5 mA, and 3 μA reverse leakage current at rated voltage - designed for precision voltage reference and overvoltage protection in automotive power rails and low-power sensor interfaces.
For engineers reviewing the PZU884LS-C3V9-QYL datasheet, PZU884LS-C3V9-QYL pinout, PZU884LS-C3V9-QYL application, or PZU884LS-C3V9-QYL equivalent, key selection criteria include side-wettable flank solderability, AEC-Q101 qualification, low dynamic impedance at microamp-level bias currents, and thermal resistance of 340 K/W on standard FR4.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain stable voltage regulation under varying load and temperature conditions. Its hard breakdown knee and low leakage (3 μA at VR = 3.9 V) enable accurate clamping in low-current bias networks and ESD-sensitive analog front-ends.
The device uses silicon planar technology with optimized doping profiles for predictable Zener behavior across −55 °C to +150 °C ambient range. Its 0.65 mm pitch, 1.0 mm × 0.6 mm footprint supports high-density automotive PCB layouts while enabling automated optical inspection via side-wettable flanks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.70 V to 4.10 V at IZ = 5 mA - defines regulated output voltage window under nominal bias |
| Differential Resistance (rdif) | 90 Ω max at IZ = 5 mA - determines regulation stiffness against load current changes |
| Reverse Leakage (IR) | 3 μA max at VR = 3.9 V - ensures minimal quiescent current draw in standby circuits |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - enables use as polarity-sensitive clamp or series diode in dual-role designs |
| Total Power Dissipation (Ptot) | 365 mW on FR4 with 70 μm Cu - sets maximum continuous DC power handling in standard layout |
| Junction Temperature (Tj) | −55 °C to +150 °C - supports operation in engine bay and ADAS control units |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C3V9,115 | ±5 % tolerance, SOT-23 package, 100 Ω rdif, 5 μA IR, no AEC-Q101 rating | Higher leakage and larger footprint limit use in automotive or battery-constrained designs | Select when cost sensitivity outweighs automotive qualification and board space constraints |
| MMSZ4685T1G | ±5 % tolerance, SOD-123 package, 120 Ω rdif, 10 μA IR, AEC-Q101 qualified | Larger 2.7 mm × 1.4 mm footprint increases PCB area by 5.5×; higher leakage reduces battery life | Choose only if legacy SOD-123 layout compatibility is mandatory and thermal performance is secondary |

FAQ
What is the maximum continuous reverse power dissipation for PZU884LS-C3V9-QYL?
The maximum continuous reverse power dissipation is 365 mW when mounted on a standard FR4 PCB with single-sided 70 μm copper and tin-plated finish. This value assumes Tamb = 25 °C and accounts for thermal resistance of 340 K/W from junction to ambient. Derating is required above 25 °C per the thermal characteristics table.
How does the side-wettable flank design improve manufacturability?
The side-wettable flanks on the DFN1006BD-2 package allow automated optical inspection (AOI) systems to verify solder joint formation without X-ray imaging. During reflow, molten solder wets the vertical sidewalls, creating a visible meniscus that AOI cameras detect - enabling 100 % inline process validation for automotive-grade assembly lines.
Is PZU884LS-C3V9-QYL suitable for bidirectional ESD protection?
No - PZU884LS-C3V9-QYL is a unidirectional Zener diode optimized for reverse-bias voltage regulation, not transient suppression. Its 40 W non-repetitive peak reverse power rating applies only to short-duration surges (tp = 100 μs), not standardized ESD waveforms like IEC 61000-4-2. For ESD protection, use purpose-built TVS diodes such as PESD5V0S1BA.
What is the temperature coefficient behavior near 3.9 V nominal voltage?
At VZ = 3.9 V, the temperature coefficient (SZ) is specified as −3.5 mV/K maximum, indicating a negative drift: output voltage decreases by up to 3.5 mV per degree Celsius rise in junction temperature. This behavior is typical for Zeners below 5 V and must be compensated in high-precision references using external circuitry or calibration.
