Product details
Overview
PZU884LS-C4V3-Q from Nexperia is a ±5 % tolerance Zener voltage regulator diode in DFN1006BD-2 (SOD882BD) package, rated for 4.01 V to 4.48 V nominal breakdown at 5 mA, with differential resistance ≤90 Ω, leakage current ≤3 μA at VR = 1 V, and qualified per AEC-Q101 for automotive power rail stabilization.
For engineers reviewing the PZU884LS-C4V3-Q datasheet, PZU884LS-C4V3-Q pinout, PZU884LS-C4V3-Q application, or PZU884LS-C4V3-Q equivalent, this device supports precision low-current voltage reference, ECU supply rail clamping, and sensor biasing where side-wettable flanks enable automated optical inspection and high-reliability reflow soldering.
Technical Context
This Zener diode operates in reverse-biased breakdown mode with hard knee characteristics optimized for stable regulation at low currents (IZ = 0.5 mA to 5 mA). Its temperature coefficient is −3.5 mV/K at IZ = 5 mA, enabling predictable drift compensation in ambient ranges from −55 °C to +150 °C.
The device features intentional low leakage (<3 μA at VR = 1 V) and low dynamic impedance (≤90 Ω at IZ = 5 mA), distinguishing it from higher-leakage variants (e.g., B-series) designed for fast switching. It is not a transient suppressor but a precision DC voltage reference element.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener voltage (VZ) | 4.01 V to 4.48 V at IZ = 5 mA - defines regulated output voltage window under nominal bias |
| Differential resistance (rdif) | ≤90 Ω at IZ = 5 mA - ensures minimal output voltage shift under load current variation |
| Reverse leakage (IR) | ≤3 μA at VR = 1 V - enables low-power standby operation without excessive quiescent drain |
| Forward voltage (VF) | ≤0.9 V at IF = 10 mA - supports bidirectional protection circuit integration when forward-biased |
| Power dissipation (Ptot) | 365 mW on FR4 PCB - sets maximum continuous DC power handling in standard layout |
| Junction temperature (Tj) | −55 °C to +150 °C - supports under-hood automotive placement without derating below −40 °C |
| AEC-Q101 qualified | Yes - validated for automotive-grade reliability including HTGB, HTRB, and temperature cycling |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a 2-terminal, leadless surface-mount package measuring 1.0 mm × 0.6 mm × 0.47 mm with side-wettable flanks for solder joint inspection. The cathode is marked by a visible bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity must be observed to maintain reverse-bias operation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes Zener conduction path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Side-wettable flanks (SWF) | Enables automated X-ray and AOI verification of solder fillet integrity on both package edges |
| ±5 % voltage tolerance | Meets cost-sensitive automotive subsystem requirements where tight regulation is secondary to robustness |
| Hard breakdown knee | Provides sharp turn-on at VZ, minimizing transitional conduction loss in reference circuits |
| Low thermal resistance (Rth(j-a)) | 340 K/W on standard FR4 - allows full 365 mW rating without heatsinking in compact layouts |
| AEC-Q101 qualification | Covers stress tests including HTRB, HTGB, and unbiased HAST - required for engine control module use |
Applications
| Engine Control Unit (ECU) Reference | Automotive Sensor Biasing |
|---|---|
Use Scenario: Stabilizing 5 V supply rail for microcontroller ADC reference in engine management systems. IC Role / Device Role / Timing Role: Zener voltage reference providing fixed bias point for analog front-end circuitry. Use Value: Maintains <±10 mV regulation error across −40 °C to +125 °C ambient due to low rdif and controlled TC. |
Use Scenario: Biasing NTC thermistors and Hall-effect sensors in transmission control modules. IC Role / Device Role / Timing Role: Low-leakage voltage clamp establishing known sensor excitation potential. Use Value: Limits IR-induced error to <0.5 mV at 10 kΩ sensor loading, preserving measurement accuracy. |
| Infotainment Power Sequencing | Body Control Module (BCM) Voltage Monitoring |
Use Scenario: Generating clean 3.3 V auxiliary rail from 5 V main supply in head unit power tree. IC Role / Device Role / Timing Role: Passive shunt regulator ensuring stable logic-level reference during startup transients. Use Value: Withstands 40 W non-repetitive surge (tp = 100 μs), protecting downstream LDOs from overvoltage events. |
Use Scenario: Monitoring 12 V battery rail via resistive divider with integrated overvoltage clamping. IC Role / Device Role / Timing Role: Fail-safe clamp limiting divider output to 4.3 V before MCU input protection diodes conduct. Use Value: Prevents latch-up by limiting input voltage to <4.5 V even during load-dump transients up to 35 V. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C4V3,115 | Same 4.3 V nominal, ±5 %, but SOT23 package (larger footprint, no SWF) | Lacks side-wettable flanks; unsuitable for automated optical solder inspection in high-volume automotive lines | Select when legacy SOT23 layout reuse is prioritized over AEC-Q101 traceability and AOI compatibility |
| MMSZ4V3ET1G | 4.3 V, ±5 %, SOD-123 package; 500 mW Ptot, but not AEC-Q101 qualified | Higher power rating but unqualified for automotive; requires additional reliability validation | Select only for industrial or consumer applications where AEC-Q101 is not mandated |
Compared with BZX84-C4V3,115 and MMSZ4V3ET1G, PZU884LS-C4V3-Q uniquely combines AEC-Q101 qualification, side-wettable flanks for process control, and ultra-small DFN1006BD-2 footprint-making it the only choice for new automotive designs requiring zero-defect solder joint assurance and space-constrained PCBs.

FAQ
What is the maximum continuous reverse current the PZU884LS-C4V3-Q can sustain without degradation?
The device supports up to 200 mA forward current per Absolute Maximum Ratings, but its Zener regulation region is specified at IZ = 0.5 mA to 5 mA. Sustained operation above 5 mA requires thermal derating based on Rth(j-a) = 340 K/W and ambient conditions; exceeding 365 mW total dissipation risks junction overheating and parameter shift.
Does the PZU884LS-C4V3-Q require external series resistance in typical regulation circuits?
Yes - a current-limiting resistor is mandatory to set IZ within 0.5 mA–5 mA for stable regulation. For a 5 V input and 4.3 V output, a 150 Ω resistor delivers ~4.7 mA, aligning with the datasheet's typical test condition and minimizing rdif-induced error while staying within Ptot limits.
How does the side-wettable flank design impact reflow soldering yield?
Side-wettable flanks allow solder to visibly wick up the vertical sidewalls during reflow, enabling automated optical inspection (AOI) to verify fillet formation and void-free joints. This eliminates reliance on X-ray for 2-terminal DFNs and improves first-pass yield in automotive contract manufacturing by >12 % versus non-SWF equivalents.
Can PZU884LS-C4V3-Q replace older PZU5000 series Zeners in existing designs?
No - PZU884LS-C4V3-Q uses DFN1006BD-2 (1.0 mm × 0.6 mm), while PZU5000 series uses SOD-323 (1.7 mm × 1.3 mm). Footprint, thermal behavior, and marking differ significantly. Migration requires PCB redesign, solder profile adjustment, and validation of regulation stability under same board-level thermal conditions.
