Product details
Overview
PZU884LS-C22-QYL from Nexperia is a ±5 % tolerance Zener voltage regulator diode with nominal 22 V breakdown voltage, ultra-low leakage current (≤0.05 μA at VR = 20 V), differential resistance of 100 Ω at IZ = 5 mA, and AEC-Q101 qualification for automotive power rail stabilization.
For engineers reviewing the PZU884LS-C22-QYL datasheet, PZU884LS-C22-QYL pinout, PZU884LS-C22-QYL application, or PZU884LS-C22-QYL equivalent, this device serves as a precision shunt reference in low-power ECU voltage monitoring, infotainment supply clamping, and ADAS sensor biasing circuits where side-wettable flank solderability and thermal robustness are critical.
Technical Context
This Zener operates in reverse-biased breakdown mode to maintain stable 22 V regulation across load and line variations, with hard breakdown knee and minimal dynamic impedance drift under 5 mA test current. Its temperature coefficient is +17 mV/K at 22 V, enabling predictable thermal drift compensation in automotive ambient ranges (−40 °C to +125 °C).
The device uses a planar silicon junction structure optimized for low noise and fast transient response, with intentional minor leakage rise per AN90031 to reduce switching-induced EMI in high-frequency power domains - distinct from the lower-leakage B-series variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 20.88 V to 23.17 V at IZ = 5 mA - defines regulated output voltage window under standard test conditions |
| Differential Resistance (rdif) | 100 Ω max at IZ = 5 mA - determines regulation stiffness and output voltage variation under load changes |
| Reverse Current (IR) | ≤0.05 μA at VR = 20 V - ensures minimal standby power loss in always-on vehicle subsystems |
| Power Dissipation (Ptot) | 365 mW on FR4 PCB - sets maximum continuous DC power handling without heatsinking |
| Non-repetitive Peak Power (PZSM) | 40 W for 100 μs - supports surge immunity against load dump transients in 12 V automotive systems |
| Junction Temperature (Tj) | −55 °C to +150 °C - enables operation in engine bay and powertrain control modules |
| Package Thermal Resistance (Rth(j-a)) | 340 K/W - quantifies self-heating under ambient convection, critical for derating in sealed enclosures |
Pinout & Package
DFN1006BD-2 (SOD882BD) leadless plastic package: 1.0 mm × 0.6 mm × 0.47 mm body, side-wettable flanks, 0.65 mm pitch, tin-plated terminals. Marking bar indicates cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; reverse-bias anode-to-cathode voltage establishes Zener breakdown |
| 2 | Anode (A) | Connected to ground or low-impedance return path; completes current loop during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints on DFN packages, improving manufacturing yield in automotive SMT lines |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTGB, HTRB, and temperature cycling - required for ASIL-B supporting functions |
| Hard breakdown knee | Sharp transition from non-conduction to regulation at 22 V minimizes ambiguity in overvoltage detection thresholds |
| Low capacitance (84 pF) | Reduces high-frequency coupling into sensitive analog rails, preserving signal integrity in camera and radar modules |
| ±5 % tolerance grade | Balances cost and precision for non-critical biasing applications where tighter tolerance is unnecessary |
Applications
| Engine Control Unit (ECU) Power Monitoring | Infotainment System Supply Clamping |
|---|---|

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-C22 | ±5 % tolerance, 350 mW Ptot, SOT23 package, no AEC-Q101 qualification | Lacks side-wettable flanks and automotive qualification; unsuitable for production automotive PCBs | Select only for prototyping or non-automotive industrial use where AOI and qualification are not required |
| MMSZ5247B | ±5 % tolerance, 500 mW Ptot, SOD-123 package, 150 °C Tj, no AEC-Q101 | Higher power rating but larger footprint and no wettable flank support for fine-pitch reflow | Prefer when board space allows and higher continuous dissipation (>365 mW) is needed, but verify AOI compatibility |
Compared with BZX84-C22 and MMSZ5247B, PZU884LS-C22-QYL uniquely combines AEC-Q101 compliance, DFN1006BD-2 side-wettable flanks for automotive SMT traceability, and optimized low-leakage/low-capacitance performance for safety-critical voltage monitoring - making it the only qualified option for volume automotive production.

FAQ
What is the maximum continuous reverse current the PZU884LS-C22-QYL can sustain at 25 °C ambient?
The device supports up to 200 mA forward current per Absolute Maximum Ratings, but as a Zener regulator, its continuous reverse current is limited by power dissipation. At 25 °C ambient on FR4 PCB, 365 mW Ptot allows ~16.6 mA average reverse current (365 mW ÷ 22 V), derating linearly above 25 °C using 340 K/W Rth(j-a).
How does the PZU884LS-C22-QYL differ from the B-series variant (e.g., PZU884LS-B22-Q)?
PZU884LS-C22-QYL uses the C-series construction with very low leakage (<0.05 μA at 20 V) and hard breakdown knee, optimized for precision regulation. The B-series has intentionally higher leakage for faster switching and noise reduction, making it better suited for transient suppression than reference stability.
Is the marking code 'MT' on the top surface sufficient to identify PZU884LS-C22-QYL on the PCB?
Yes - per Table 4 of the datasheet, 'MT' is the exclusive marking code for PZU884LS-C22-QYL. The marking bar adjacent to pin 1 confirms cathode orientation, and the DFN1006BD-2 footprint (1.0 mm × 0.6 mm) further validates correct placement during AOI inspection.
Can PZU884LS-C22-QYL be used in parallel for higher power dissipation?
No - Zener diodes exhibit negative temperature coefficients below ~5 V and positive above, causing current hogging in parallel configurations. For >365 mW needs, use a single higher-rated Zener or implement active regulation; paralleling PZU884LS-C22-QYL risks thermal runaway and premature failure.
