Product details
Overview
PZU884LS-B2V7-QYL from Nexperia is a ±2 % tolerance Zener voltage regulator diode in DFN1006BD-2 (SOD882BD) package, rated for 2.7 V nominal breakdown voltage at 5 mA, with 1000 Ω differential resistance and 1.0 μA reverse leakage at 2.0 V. It delivers stable reference voltage in space-constrained automotive power rails and low-voltage microcontroller I/O protection circuits.
For engineers reviewing the PZU884LS-B2V7-QYL datasheet, PZU884LS-B2V7-QYL pinout, PZU884LS-B2V7-QYL application, or PZU884LS-B2V7-QYL equivalent, this device supports AEC-Q101-compliant voltage clamping, low-current regulation, and side-wettable-flank reflow compatibility in ultra-small 1.0 mm × 0.6 mm footprints.
Technical Context
This Zener diode operates in reverse-bias breakdown mode to maintain a precise 2.7 V reference across its cathode–anode terminals under regulated current conditions. Its hard breakdown knee and low dynamic impedance ensure minimal voltage deviation during transient load shifts in 3.3 V and 5 V supply domains.
Designed for automotive-grade reliability, it features side-wettable flanks enabling automated optical solder-joint inspection and complies with AEC-Q101 stress testing including temperature cycling, HTRB, and ESD. Junction temperature remains within safe limits up to 150 °C with 340 K/W thermal resistance to ambient on standard FR4 PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.7 V nominal at IZ = 5 mA; tight ±2 % tolerance ensures predictable clamping in 3.3 V rail monitoring |
| Differential Resistance (rdif) | 1000 Ω max at IZ = 5 mA; defines voltage shift per mA change in bias current |
| Reverse Leakage (IR) | 1.0 μA max at VR = 2.0 V; enables low-power standby regulation without excessive quiescent drain |
| Total Power Dissipation (Ptot) | 365 mW at Tamb = 25 °C on FR4; sets maximum continuous DC power handling in compact layouts |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 μs; supports transient overvoltage suppression in ESD or load-dump events |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA; confirms low-loss forward conduction for polarity-sensitive protection schemes |
| Junction Temperature (Tj) | 150 °C absolute max; allows operation in under-hood automotive environments without derating |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a leadless 2-terminal surface-mount package measuring 1.0 mm × 0.6 mm × 0.47 mm with side-wettable flanks for automated solder-joint inspection. The marking bar identifies the cathode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; accepts reverse-bias current to establish stable Zener voltage |
| 2 (A) | Anode | Connected to ground or lower-potential rail; completes bias path for breakdown conduction |
Key Features

| AEC-Q101 qualification | Validated for automotive power management, including engine control units and ADAS sensor modules |
| Hard breakdown knee | Ensures sharp, repeatable turn-on behavior critical for precision voltage clamping in low-noise analog rails |
| Ultra-small footprint | 1.0 mm × 0.6 mm body area reduces board space by >60 % versus SOD-323 Zeners in same voltage class |
| Low leakage at low VR | 1.0 μA at 2.0 V enables use in battery-backed circuits where standby current must stay below 2 μA |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B2V7 | Same 2.7 V ±2 % rating but in SOD-323 package (1.7 mm × 1.3 mm); 1200 Ω rdif; no AEC-Q101 qualification | Larger footprint increases board area; higher dynamic impedance degrades regulation under fast load steps | Select only for non-automotive consumer designs where cost outweighs size and reliability requirements |
| MMSZ4678 | 2.7 V ±5 % tolerance in SOD-123; 1500 Ω rdif; 5 μA IR at 2.0 V; not AEC-Q101 qualified | Loose tolerance and higher leakage limit use in precision references or ultra-low-power systems | Acceptable for cost-sensitive industrial controls where ±5 % regulation is sufficient and 150 °C operation not required |
Compared with BZX384-B2V7 and MMSZ4678, PZU884LS-B2V7-QYL offers superior automotive compliance, 30 % smaller footprint, and 4× lower leakage-making it the only choice for AEC-Q101–mandated, space-constrained, low-quiescent designs.

FAQ
What is the maximum continuous reverse current this Zener can handle at 25 °C?
The device supports up to 200 mA forward current per Absolute Maximum Ratings, but for Zener operation, the practical continuous reverse current is limited by power dissipation. At 25 °C ambient and 2.7 V VZ, the maximum safe DC reverse current is approximately 135 mA (365 mW ÷ 2.7 V), assuming no additional thermal resistance beyond the specified 340 K/W junction-to-ambient value.
Does the side-wettable flank design require special stencil or reflow profile adjustments?
No special stencil modifications are needed-the standard DFN1006BD-2 footprint (1.3 mm × 0.8 mm solder lands, 0.4 mm paste thickness) specified in Figure 10 supports full wetting. Reflow profiles follow IPC-J-STD-020 for MSAL3 moisture sensitivity level, with peak temperature ≤ 260 °C and time above liquidus 60–90 seconds.
How does the temperature coefficient behave near 2.7 V nominal voltage?
At 2.7 V nominal, the temperature coefficient (SZ) is −3.5 mV/K, meaning the Zener voltage decreases by 3.5 mV per 1 K rise in junction temperature. This negative drift is typical for low-voltage Zeners and must be accounted for in wide-temperature-range reference designs.
Can this part replace older PZU5000-series Zeners in existing layouts?
No direct replacement is possible due to package mismatch: PZU5000-series uses SOD-123 (3.7 mm × 1.6 mm), while PZU884LS-B2V7-QYL uses DFN1006BD-2 (1.0 mm × 0.6 mm). Layout redesign is required, but the smaller footprint enables denser routing and improved thermal performance on thermally constrained boards.
