Product details
Overview
PZU884LS-B7V5-QYL from Nexperia is a leadless SOD882BD (DFN1006BD-2) Zener voltage regulator diode with nominal 7.5 V breakdown voltage, ±2 % tolerance, 60 Ω differential resistance at IZ = 5 mA, and AEC-Q101 qualification for automotive use in power rail stabilization and reference circuits.
For engineers reviewing the PZU884LS-B7V5-QYL datasheet, PZU884LS-B7V5-QYL pinout, PZU884LS-B7V5-QYL application, or PZU884LS-B7V5-QYL equivalent, key selection criteria include low dynamic impedance at low currents, side-wettable flanks for automated optical inspection, thermal resistance of 340 K/W, and compatibility with reflow-soldered ultra-compact PCB layouts.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain stable 7.5 V regulation across load and line variations, with hard breakdown knee and very low leakage current (< 0.5 μA at VR = 5.6 V). Its DFN1006BD-2 package enables high-density placement while supporting IPC Class 3 solder joint reliability via side-wettable flanks.
The device exhibits a temperature coefficient of +2.5 mV/K at IZ = 5 mA and junction-to-ambient thermal resistance of 340 K/W on standard FR4, enabling operation up to 150 °C ambient in automotive under-hood environments. It delivers 365 mW continuous power dissipation and withstands 40 W non-repetitive surge pulses (tp = 100 μs).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 7.06 V to 7.84 V at IZ = 5 mA - tight ±2 % tolerance ensures precise voltage clamping in feedback loops |
| Differential Resistance rdif | 60 Ω max at IZ = 5 mA - low impedance maintains regulation stability under varying load current |
| Reverse Leakage IR | ≤ 0.5 μA at VR = 5.6 V - minimal standby current preserves battery life in always-on systems |
| Forward Voltage VF | ≤ 0.9 V at IF = 10 mA - enables low-loss forward conduction during transient recovery |
| Power Dissipation Ptot | 365 mW on FR4 PCB - sufficient for local rail regulation without heatsinking in space-constrained modules |
| Junction Temperature Tj | −55 °C to +150 °C - supports extended-temperature automotive and industrial operation |
| Package | DFN1006BD-2 (SOD882BD), 1.0 mm × 0.6 mm × 0.47 mm - ultra-small footprint with side-wettable flanks for AOI-compatible assembly |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a 2-terminal leadless plastic package with side-wettable flanks, 0.65 mm pitch, and cathode indicated by a marking bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity-sensitive terminal requiring correct PCB orientation for reverse-bias operation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes Zener conduction path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints without X-ray, reducing post-reflow defect escape in high-volume automotive manufacturing |
| AEC-Q101 qualification | Validated for automotive applications including engine control units, body electronics, and ADAS sensors per stress test requirements for discrete semiconductors |
| Hard breakdown knee | Sharp transition into conduction at VZ improves regulation accuracy and reduces overshoot during transient suppression |
| Low dynamic impedance | 60 Ω typical at 5 mA enables stable reference voltage generation for ADCs and comparators in noise-sensitive analog subsystems |
| Ultra-small footprint | 1.0 mm × 0.6 mm area saves >60 % board space vs. traditional SOD-323 packages, critical for compact ECU and infotainment modules |

FAQ
What is the maximum continuous reverse power dissipation for PZU884LS-B7V5-QYL?
The maximum continuous total power dissipation is 365 mW when mounted on a standard FR4 PCB with single-sided 70 μm copper and tin-plated finish. This rating assumes Tamb = 25 °C and accounts for the device's 340 K/W junction-to-ambient thermal resistance. Derating is required above 25 °C ambient per the thermal characteristics table.
How does the side-wettable flank design benefit manufacturing?
The side-wettable flanks on the DFN1006BD-2 package allow automated optical inspection (AOI) systems to verify solder fillet formation on all four side edges without requiring X-ray imaging. This reduces inspection cost and increases throughput in high-volume automotive electronics assembly lines while maintaining IPC Class 3 process control.
Is PZU884LS-B7V5-QYL suitable for use as a voltage reference in precision analog circuits?
Yes-it provides ±2 % initial tolerance, +2.5 mV/K temperature coefficient, and 60 Ω differential resistance at 5 mA, enabling stable 7.5 V references for 12-bit ADCs and comparator circuits. Its low 0.5 μA leakage at 5.6 V minimizes loading error in high-impedance divider networks commonly used in sensor interfaces.
What is the significance of the 'B' suffix in PZU884LS-B7V5-QYL?
The 'B' denotes the ±2 % tolerance grade within the PZU884LS-Q series, distinguishing it from 'C' grade parts with approximately ±5 % tolerance. The 'B' variant is specified for tighter regulation accuracy and is recommended for applications requiring higher voltage stability, such as automotive microcontroller supply monitoring and precision analog references.
