Product details
Overview
PZU884LS-C47-Q from Nexperia is a ±5 % tolerance Zener voltage regulator diode with nominal 47 V breakdown voltage, 375 Ω differential resistance at 2 mA, 0.05 μA reverse current at 32.9 V, and AEC-Q101 qualification for automotive power rail stabilization in engine control units and ADAS sensor modules.
For engineers reviewing the PZU884LS-C47-Q datasheet, PZU884LS-C47-Q pinout, PZU884LS-C47-Q application, or PZU884LS-C47-Q equivalent, this page delivers verified Zener parameters, side-wettable DFN1006BD-2 package handling guidance, automotive-grade thermal derating curves, and validated alternatives for 47 V reference design.
Technical Context
This Zener operates in reverse-biased breakdown mode to maintain stable 47 V regulation across load and line variations. Its 375 Ω dynamic impedance at 2 mA ensures tight voltage control under low-current bias conditions typical in precision reference circuits.
The device features intentional leakage optimization per AN90031 for fast switching and noise reduction, with temperature coefficient of +42.0 mV/K at 2 mA and junction-to-ambient thermal resistance of 340 K/W on FR4 PCB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 44.0 V to 50.0 V at IZ = 2 mA - defines regulation band for 47 V nominal rail |
| Differential Resistance (rdif) | 375 Ω at IZ = 2 mA - determines output impedance and load regulation error |
| Reverse Current (IR) | 0.05 μA at VR = 32.9 V - enables ultra-low quiescent power in always-on monitoring circuits |
| Power Dissipation (Ptot) | 365 mW at Tamb = 25 °C - sets maximum continuous DC power on standard FR4 layout |
| Junction Temperature (Tj) | −55 °C to +150 °C - supports operation in under-hood automotive environments |
| Package Thermal Resistance (Rth(j-a)) | 340 K/W - informs thermal design margin for ambient temperatures up to 125 °C |

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-C47,115 | ±5 % tolerance, 600 Ω rdif at 5 mA, SOT23 package, no AEC-Q101 qualification | Larger footprint (2.9 mm²), higher dynamic impedance, not automotive-qualified | Select for cost-sensitive industrial designs where AEC-Q101 is not mandated |
| MMSZ47ET1G | ±5 % tolerance, 100 Ω rdif at 1 mA, SOD-123 package, AEC-Q101 qualified | Higher leakage (1.0 μA at 32.9 V), larger body (2.7 mm²), no side-wettable flanks | Select when lower dynamic impedance is critical and AOI inspection is not required |
Compared with PZU884LS-C47-Q, BZX84-C47 offers lower cost but lacks automotive qualification and compactness, while MMSZ47ET1G improves impedance but sacrifices leakage performance and manufacturability via side-wettable flanks.

FAQ
What is the maximum continuous forward current rating for PZU884LS-C47-Q?
The device is a Zener diode intended for reverse-bias operation; its absolute maximum forward current is 200 mA per Table 5, but forward conduction is not part of its functional specification. Forward voltage is specified at 10 mA (≤0.9 V), confirming it is not designed for rectification duty.
Does PZU884LS-C47-Q require a heatsink for 365 mW operation?
No external heatsink is required. The 365 mW total power dissipation rating assumes mounting on a standard FR4 PCB with single-sided 70 μm copper and tin plating. Thermal resistance of 340 K/W means junction temperature rise is ~124 K above ambient at full power, staying within the 150 °C limit at ≤26 °C ambient.
How does the "C" suffix in PZU884LS-C47-Q affect its electrical behavior versus "B" variants?
The "C" suffix denotes the ±5 % tolerance series with optimized leakage for fast switching and noise reduction (per AN90031), whereas "B" variants offer ±2 % tolerance and lower leakage but higher dynamic impedance. For PZU884LS-C47-Q, this yields 375 Ω rdif at 2 mA versus ~400 Ω for the B47 variant, with intentional 0.05 μA IR at 32.9 V.
Can PZU884LS-C47-Q be used in parallel for higher power handling?
Parallel connection is not recommended due to mismatched Zener voltage tolerances and thermal runaway risk. The device's 40 W non-repetitive peak power is intended for transient suppression only. For sustained higher power, use a dedicated TVS or active regulator instead of paralleling Zeners.
