Product details
Overview
PZU884LS-B39-Q from Nexperia is a leadless SOD882BD (DFN1006BD-2) Zener voltage regulator diode with nominal 39 V breakdown voltage, ±2 % tolerance, and 350 Ω differential resistance at IZ = 2 mA - designed for precision voltage reference and overvoltage clamping in automotive power rails and sensor supply circuits.
For engineers reviewing the PZU884LS-B39-Q datasheet, PZU884LS-B39-Q pinout, PZU884LS-B39-Q application, or PZU884LS-B39-Q equivalent, key selection criteria include its AEC-Q101 qualification, side-wettable flanks for automated optical inspection, low leakage (<0.05 μA at VR = 39 V), and thermal resistance of 340 K/W on FR4 PCB.
Technical Context
This Zener diode operates in reverse-biased breakdown mode with a hard knee and stable regulation at 39 V nominal, optimized for low-current biasing (IZ = 2 mA typical). Its temperature coefficient is +27.3 mV/K at IZ = 2 mA, enabling predictable drift compensation in automotive ambient ranges (−40 °C to +125 °C).
The device uses silicon planar technology in a 2-terminal DFN package with cathode marked by a bar. It delivers non-repetitive surge capability up to 40 W (tp = 100 μs) and supports continuous dissipation of 365 mW under standard FR4 mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 39 V - precise regulation point for 3.3 V/5 V rail monitoring and ECU reference buffering |
| Tolerance | ±2 % - tight initial accuracy enables single-diode reference without trimming |
| Differential Resistance | 350 Ω at IZ = 2 mA - low impedance ensures stable output under varying load current |
| Reverse Leakage Current | <0.05 μA at VR = 39 V - minimal standby power loss in always-on automotive modules |
| Power Dissipation | 365 mW - sufficient for transient clamping and biasing in compact PCB layouts |
| Package Thermal Resistance | 340 K/W - defines junction-to-ambient rise under continuous operation on standard FR4 |
| Surge Power Rating | 40 W (100 μs square wave) - handles ISO 7637-2 pulse 1/2/5a transients without failure |

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-C39 | ±5 % tolerance, 600 Ω rdif at 5 mA, SOT23 package, no AEC-Q101 qualification | Not suitable for automotive production; limited to consumer-grade power supervision | Select only for cost-sensitive non-automotive designs where ±5 % tolerance is acceptable |
| MMSZ5241B | ±5 % tolerance, 17 Ω rdif at 20 mA, SOD-123 package, no side-wettable flanks | Lacks AOI compatibility and automotive qualification; higher rdif at low current | Prefer for high-current regulation (>10 mA), but avoid in space-constrained or automotive AOI-critical layouts |
Compared with PZU884LS-B39-Q, BZX84-C39 offers lower unit cost but sacrifices accuracy, surge robustness, and automotive compliance; MMSZ5241B provides lower impedance at high current but lacks side-wettable flanks and fails AEC-Q101 - making PZU884LS-B39-Q the sole choice for production automotive Zener reference/clamp functions requiring AOI, ±2 %, and 40 W surge handling.

FAQ
What is the maximum continuous reverse power dissipation for PZU884LS-B39-Q?
The maximum continuous reverse power dissipation is 365 mW when mounted on a standard FR4 PCB with single-sided 70 μm copper and tin plating. This value assumes Tamb = 25 °C and accounts for thermal resistance of 340 K/W. Derating is required above 25 °C ambient per the thermal characteristics table.
Does PZU884LS-B39-Q support automated optical inspection (AOI)?
Yes - its DFN1006BD-2 package features side-wettable flanks, enabling reliable solder-joint inspection using standard AOI systems without requiring X-ray. This is confirmed in the package outline documentation and is a defined feature of the SOD882BD footprint.
How does the temperature coefficient affect regulation accuracy at 39 V?
At IZ = 2 mA, the temperature coefficient is +27.3 mV/K. Over a −40 °C to +125 °C range (165 K delta), this yields ~4.5 V total drift - meaning regulation shifts from ~37.2 V to ~41.7 V. System-level compensation or tolerance budgeting must account for this linear drift.
Can PZU884LS-B39-Q replace older PZUxxLS-B39 variants in existing designs?
Yes - PZU884LS-B39-Q is a direct replacement for prior PZU884LS-B39 revisions (e.g., Rev. 3), maintaining identical electrical specs, package dimensions, pinout, and marking. The Rev. 4 datasheet confirms backward compatibility and no changes to limiting values or characteristics.
