Product details
Overview
PZU884LS-B24-QYL from Nexperia is a 24 V ±2 % tolerance Zener voltage regulator diode in a DFN1006BD-2 (SOD882BD) leadless SMD package with side-wettable flanks, designed for precision voltage reference and clamping in automotive power rails and low-power analog circuits; features 19 Ω differential resistance at IZ = 5 mA, <0.05 μA reverse current at VR = 19.2 V, and AEC-Q101 qualification.
For engineers reviewing the PZU884LS-B24-QYL datasheet, PZU884LS-B24-QYL pinout, PZU884LS-B24-QYL application, or PZU884LS-B24-QYL equivalent, this page delivers verified electrical parameters, thermal performance under PCB-mount conditions, automotive-grade reliability data, and real-world use context for voltage stabilization in compact, high-reliability designs.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable 24 V regulation across load and line variations, with a hard breakdown knee and low dynamic impedance optimized for low-current biasing (IZ = 5 mA typical). Its temperature coefficient of +18.4 mV/K at 24 V enables predictable drift compensation in temperature-sensitive references.
The device uses silicon planar epitaxial construction with side-wettable flanks for automated optical solder-joint inspection, and its 0.65 mm pitch, 1.0 mm × 0.6 mm footprint supports high-density layout in ADAS sensor modules and body control units where space and reliability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 22.93 V to 25.57 V at IZ = 5 mA - ensures tight 24 V regulation for MCU supply rail monitoring |
| Differential Resistance (rdif) | 120 Ω max at IZ = 5 mA - maintains low output impedance for stable reference under varying load |
| Reverse Current (IR) | <0.05 μA at VR = 19.2 V - minimizes standby power loss in always-on automotive subsystems |
| Power Dissipation (Ptot) | 365 mW on FR4 PCB - supports continuous operation in thermally constrained ECUs without heatsinking |
| Junction Temperature (Tj) | −55 °C to +150 °C - enables deployment in engine bay and powertrain control environments |
| Thermal Resistance (Rth(j-a)) | 340 K/W - defines thermal rise per watt on standard single-layer copper, critical for lifetime prediction |
| Capacitance (Cd) | 80 pF at f = 1 MHz, VR = 0 V - limits high-frequency noise coupling in signal conditioning paths |
Pinout & Package
DFN1006BD-2 (SOD882BD) ultra-small leadless plastic package: 1.0 mm × 0.6 mm × 0.47 mm body, 0.65 mm pitch, side-wettable flanks for AOI-compatible reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated voltage node; marking bar identifies this terminal for correct orientation during placement |
| 2 (A) | Anode | Connected to ground or lower-potential rail; forms reverse-biased junction enabling Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, lighting, and infotainment power domains |
| Side-wettable flanks | Enables automated optical inspection of solder joints without X-ray, reducing manufacturing defect escape |
| ±2 % voltage tolerance | Supports tighter system-level voltage margining than ±5 % variants, improving ADC reference accuracy |
| Hard breakdown knee | Ensures sharp turn-on at rated VZ, minimizing regulation error during transient overvoltage events |
| Low leakage at 80 % VZ | Reduces quiescent current in battery-backed circuits, extending sleep-mode runtime in telematics modules |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C24,115 | ±5 % tolerance, 350 mW Ptot, SOT23 package (3.0 mm × 1.4 mm) | Larger footprint, higher leakage (>1 μA at 19.2 V), no AEC-Q101 qualification | Select for cost-sensitive non-automotive industrial designs where size and automotive compliance are not required |
| MMSZ5242B-TP | ±5 % tolerance, 500 mW Ptot, SOD-123 package (3.7 mm × 1.6 mm) | Higher power rating but 3× larger area; rdif = 35 Ω (worse regulation stability at low current) | Choose when higher surge handling (e.g., 100 ms transients) is needed and board space permits larger package |
Compared with BZX84-C24,115 and MMSZ5242B-TP, PZU884LS-B24-QYL offers superior automotive qualification, 40 % smaller footprint, and tighter voltage tolerance-making it optimal for space-constrained, safety-critical 24 V systems where long-term drift and solder-joint reliability are design priorities.

FAQ
What is the maximum reverse power dissipation for PZU884LS-B24-QYL during transient surges?
The non-repetitive peak reverse power dissipation (PZSM) is 40 W for 100 μs square-wave pulses at Tj = 25 °C prior to surge. This enables protection against ISO 7637-2 Pulse 1 and Pulse 4a transients when used with appropriate series impedance, but repeated surges must respect thermal limits defined by Rth(j-a) = 340 K/W.
How does the temperature coefficient affect regulation accuracy over automotive temperature ranges?
At 24 V nominal, the temperature coefficient is +18.4 mV/K. Over −40 °C to +125 °C (165 K span), total VZ drift is approximately ±1.5 V - fully characterized in Table 8 and compensated in system calibration routines. This drift is predictable and monotonic, supporting first-order correction in firmware.
Can PZU884LS-B24-QYL be used in parallel for higher current capability?
No - Zener diodes exhibit negative temperature coefficients below ~5 V and positive above, causing current hogging in parallel configurations. The PZU884LS-B24-QYL's +18.4 mV/K coefficient makes mismatched thermal coupling highly likely, risking thermal runaway. Use a single device sized for full load or select a higher-power alternative.
Is the DFN1006BD-2 package compatible with standard reflow profiles for lead-free assembly?
Yes - Nexperia specifies compatibility with IPC/JEDEC J-STD-020 moisture sensitivity level 1 and JEDEC-standard lead-free reflow profiles (peak 260 °C, 30 s max). The side-wettable flanks are validated for solder paste volume control and post-reflow AOI, eliminating need for special stencil designs or nitrogen atmosphere.
