Product details
Overview
PZU884LS-C51-Q from Nexperia is a Zener voltage regulator diode with nominal 51 V breakdown voltage, ±5 % tolerance, ultra-small DFN1006BD-2 (SOD882BD) package, side-wettable flanks, and AEC-Q101 qualification for automotive power rail stabilization and ESD protection in engine control units.
For engineers reviewing the PZU884LS-C51-Q datasheet, PZU884LS-C51-Q pinout, PZU884LS-C51-Q application, or PZU884LS-C51-Q equivalent, key selection criteria include its 51 V nominal Zener voltage at IZ = 2 mA, differential resistance of 400 Ω, temperature coefficient of +0.05 mV/K, non-repetitive peak reverse power dissipation of 40 W, and junction temperature rating up to 150 °C.
Technical Context
This device operates as a two-terminal shunt voltage reference, maintaining stable regulation across ambient temperatures from −55 °C to +150 °C with a hard breakdown knee and intentional minor leakage current optimized for fast switching and noise reduction per AN90031. Its thermal resistance from junction to ambient is 340 K/W on standard FR4 PCB.
The PZU884LS-C51-Q exhibits low dynamic impedance (400 Ω at IZ = 2 mA) and low capacitance (40 pF at f = 1 MHz), enabling effective high-frequency noise suppression in DC-DC feedback paths and overvoltage clamping circuits where precise 51 V thresholding is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 48.0 V to 54.0 V at IZ = 2 mA - defines clamping threshold for 51 V nominal rail protection |
| Differential Resistance rdif | 400 Ω max at IZ = 2 mA - determines regulation stiffness under load transients |
| Reverse Current IR | 180 μA max at VR = 35.7 V - sets leakage-induced quiescent power loss in standby mode |
| Non-repetitive Peak Power PZSM | 40 W at tp = 100 μs - supports transient surge suppression per ISO 7637-2 Pulse 1/2b |
| Junction Temperature Tj | −55 °C to +150 °C - enables operation in under-hood automotive environments |
| Total Power Dissipation Ptot | 365 mW at Tamb = 25 °C on FR4 - limits continuous thermal design margin without heatsinking |
| Package | DFN1006BD-2 (SOD882BD), 1.0 mm × 0.6 mm × 0.47 mm - enables high-density layout in space-constrained ECUs |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a leadless, surface-mount plastic package with side-wettable flanks, 0.65 mm pitch, and 2 terminals. The marking bar indicates the cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints on bottom-side terminations |
| Optimized leakage profile | Intentional minor rise in IR improves switching speed and reduces high-frequency noise in clamp applications |
| Hard breakdown knee | Sharp V-I transition at 51 V ensures predictable clamping onset without soft saturation |
| Low capacitance | 40 pF at 1 MHz minimizes signal distortion in high-speed data line protection circuits |
Applications
| Engine Control Unit (ECU) Power Rail Clamp | Automotive Infotainment DC-DC Feedback Reference |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C51,115 | Same 51 V nominal, ±5 %, but SOT23 package (2.9 mm × 1.3 mm); higher Rth(j-a) = 375 K/W; no AEC-Q101 qualification | Acceptable for non-automotive industrial use; unsuitable for under-hood mounting due to thermal and qualification gaps | Select only for cost-sensitive consumer designs where AEC-Q101 and space constraints are not critical |
| MMSZ5257ET1G | 51 V nominal, ±5 %, SOD-123 package (3.7 mm × 1.6 mm); 600 mW Ptot; no side-wettable flanks; AEC-Q101 qualified | Higher power handling supports longer surge durations but requires 3.5× more board area than DFN1006BD-2 | Prefer when system-level surge testing exceeds 40 W/100 μs or AOI of solder joints is not required |
Compared with BZX84-C51,115 and MMSZ5257ET1G, the PZU884LS-C51-Q uniquely combines AEC-Q101 compliance, ultra-miniature footprint, side-wettable flanks for process control, and optimized leakage for noise-sensitive automotive clamping-making it the only choice for next-generation compact ECU and ADAS modules.

FAQ
What is the maximum non-repetitive peak reverse power the PZU884LS-C51-Q can handle?
The PZU884LS-C51-Q supports up to 40 W of non-repetitive peak reverse power dissipation (PZSM) for pulse durations of 100 μs at Tj = 25 °C prior to surge, as defined in Table 5 of the datasheet. This rating aligns with ISO 7637-2 Pulse 1 and Pulse 2b test requirements for automotive electronics.
How does the PZU884LS-C51-Q differ from earlier PZU884LS-B51-Q in terms of leakage and switching behavior?
The PZU884LS-C51-Q features an intentionally increased reverse leakage current versus the B-series, as stated in Section 2, enabling faster switching response and reduced high-frequency noise-critical for clamping fast transients in ADAS and EPS systems. The B-series prioritizes ultra-low leakage for precision reference use.
Is the DFN1006BD-2 package compatible with standard reflow profiles for lead-free soldering?
Yes-the DFN1006BD-2 package is qualified for standard IPC/JEDEC J-STD-020D reflow profiles, including peak temperatures up to 260 °C. Figure 10 provides the recommended solder land pattern, and Section 13 confirms compatibility with Type 3 solder paste and standard stencil thicknesses.
Can the PZU884LS-C51-Q be used in place of a 51 V Zener in a linear regulator feedback loop?
Yes-it functions as a shunt reference in feedback dividers, but its 400 Ω differential resistance and ±5 % tolerance must be factored into output voltage error budget. For high-accuracy regulation, pairing with a precision op-amp buffer or using it solely for overvoltage clamping is recommended per application note AN90031.
