Product details
Overview
PZU884LS-C3V3-QYL from Nexperia is a ±5 % tolerance Zener voltage regulator diode in DFN1006BD-2 (SOD882BD) package, rated for 3.3 V nominal breakdown at 5 mA, with 95 Ω differential resistance, 1.0 μA reverse current at 1.0 V, and AEC-Q101 qualification for automotive power rail stabilization.
For engineers reviewing the PZU884LS-C3V3-QYL datasheet, PZU884LS-C3V3-QYL pinout, PZU884LS-C3V3-QYL application, or PZU884LS-C3V3-QYL equivalent, key selection criteria include low-leakage Zener regulation at 3.3 V, side-wettable flank solderability, thermal resistance of 340 K/W on FR4, and compatibility with 0.65 mm pitch reflow footprints.
Technical Context
This device operates as a two-terminal shunt voltage reference, maintaining stable 3.3 V regulation under reverse bias with hard breakdown knee and low dynamic impedance. Its design targets low-current precision regulation where leakage and temperature coefficient must be tightly controlled.
The ±5 % tolerance grade (C-series) delivers optimized noise performance and fast switching response via intentional minor leakage rise, per AN90031. Junction temperature range spans −55 °C to +150 °C, supporting under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 3.3 V at IZ = 5 mA - defines primary regulation point for 3.3 V supply rail clamping |
| Tolerance | ±5 % - specifies allowable deviation (3.10 V to 3.50 V) for cost-sensitive automotive subsystems |
| Differential Resistance | 95 Ω at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Reverse Current | 1.0 μA at VR = 1.0 V - confirms low standby leakage critical for battery-backed circuits |
| Power Dissipation | 365 mW at Tamb = 25 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Junction Temperature | −55 °C to +150 °C - enables operation in engine control units and ADAS sensor modules |
| Package | DFN1006BD-2 (SOD882BD), 1.0 mm × 0.6 mm × 0.47 mm - ultra-small leadless footprint with side-wettable flanks for automated optical inspection |

Applications
| Engine Control Unit (ECU) Power Monitoring | Automotive Camera Module Reference |
|---|---|
Use Scenario: Stabilizing 3.3 V supply for microcontroller ADC reference and CAN transceiver biasing in engine bay environments. IC Role / Device Role / Timing Role: Shunt Zener regulator providing precise, temperature-stable voltage clamp independent of load current variation. Use Value: Maintains ADC accuracy within ±0.5 % across −40 °C to +125 °C ambient due to low 3.3 V temperature coefficient and AEC-Q101 thermal robustness. |
Use Scenario: Biasing image sensor analog front-end and providing clean reference for auto-exposure control circuitry. IC Role / Device Role / Timing Role: Low-noise voltage reference suppressing supply ripple-induced fixed-pattern noise in CMOS image sensors. Use Value: 1.0 μA leakage at 1.0 V prevents dark-current drift; 95 Ω dynamic impedance rejects >60 dB of 100 kHz–1 MHz switching noise from DC/DC converters. |
| Body Control Module (BCM) IO Protection | Infotainment System Level-Shifting |
Use Scenario: Clamping LIN bus transceiver input pins against ESD and load-dump transients in door module electronics. IC Role / Device Role / Timing Role: Fast-response overvoltage protector absorbing surge energy while holding line voltage ≤3.6 V. Use Value: 40 W non-repetitive peak reverse power dissipation (100 μs pulse) withstands ISO 7637-2 Pulse 1/2a without degradation. |
Use Scenario: Generating stable 3.3 V reference for level-shifter ICs interfacing 1.8 V SoC with 5 V display interface. IC Role / Device Role / Timing Role: Precision voltage source enabling accurate logic threshold translation with minimal offset error. Use Value: ±5 % tolerance ensures level-shifter enable thresholds remain within 3.10–3.50 V window, preventing false triggering across temperature and voltage corners. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C3V3,115 | Same 3.3 V ±5 % rating but SOT23 package; higher Rth(j-a) = 450 K/W; no AEC-Q101 qualification | Limited to consumer-grade portable devices; unsuitable for under-hood automotive use | Select only for cost-sensitive non-automotive designs where board space allows SOT23 and thermal margin exceeds 100 °C/W |
| MMSZ5226ET1G | SOD-123 package; 3.3 V ±5 %; Rdiff = 130 Ω; 10 μA leakage at 1.0 V; AEC-Q101 qualified | Higher leakage degrades battery life in always-on modules; larger footprint consumes 3× PCB area | Prefer when legacy SOD-123 layout exists and leakage <5 μA is not required; avoid in compact camera modules |
Compared with BZX84-C3V3,115 and MMSZ5226ET1G, PZU884LS-C3V3-QYL uniquely combines AEC-Q101 compliance, ultra-small DFN1006BD-2 footprint, sub-2 μA leakage, and side-wettable flanks-making it the only choice for next-generation automotive vision systems requiring zero-defect solder joints and thermal resilience.

FAQ
What is the maximum continuous forward current for PZU884LS-C3V3-QYL?
The device is a Zener diode operated in reverse breakdown; forward current is not a functional parameter. Its absolute maximum forward current is 200 mA per limiting values table, but forward conduction is avoided in regulation applications. The 0.9 V forward voltage at 10 mA is specified only for characterization and ESD testing contexts.
Does PZU884LS-C3V3-QYL require a series resistor in typical regulation circuits?
Yes-a current-limiting resistor is mandatory to set the Zener operating current between 0.5 mA and 20 mA. For 3.3 V regulation from a 5 V rail, a 1.0 kΩ resistor delivers 1.7 mA, ensuring stable breakdown while staying within 365 mW power limit and avoiding thermal runaway.
How does the "C" suffix in PZU884LS-C3V3-QYL differ from "B" in the same series?
The "C" denotes ±5 % tolerance and optimized low-leakage performance (1.0 μA at 1.0 V), targeting precision regulation. The "B" grade offers ±2 % tolerance but higher leakage (5 μA at 1.0 V) and is intended for noise-sensitive switching applications per AN90031.
Can PZU884LS-C3V3-QYL be used in place of a TL431-based shunt regulator?
No-it lacks the adjustable reference, op-amp, and transistor output stage of TL431. PZU884LS-C3V3-QYL provides fixed 3.3 V clamping only; it cannot replicate TL431's programmable threshold, 2.5 V reference, or 100 mA sink capability. Use only for simple voltage limiting, not active feedback regulation.
