Product details
Overview
PZU884LS-C39-Q from Nexperia is a Zener voltage regulator diode in the PZU884LS-Q series, designed for precision voltage reference and clamping in automotive-grade power rails. It delivers a nominal 39 V Zener voltage with ±5 % tolerance, 350 Ω differential resistance at IZ = 2 mA, and operates up to 150 °C junction temperature. Its ultra-small DFN1006BD-2 (SOD882BD) package supports high-density PCB layouts in engine control units and ADAS sensor modules.
For engineers reviewing the PZU884LS-C39-Q datasheet, PZU884LS-C39-Q pinout, PZU884LS-C39-Q application, or PZU884LS-C39-Q equivalent, this page provides verified technical context, automotive-qualified thermal and electrical specifications, side-wettable flank soldering guidance, and validated alternative options for 39 V Zener regulation.
Technical Context
This Zener diode belongs to the "C" tolerance series (±5 %), optimized for stable regulation at higher voltages (39 V to 51 V) with intentional minor leakage current to improve switching speed and reduce noise-per AN90031. It exhibits a typical temperature coefficient of +27.3 mV/K at IZ = 2 mA and maintains low capacitance (45 pF at f = 1 MHz, VR = 0 V).
Rated for AEC-Q101 qualification, it supports non-repetitive peak reverse power dissipation of 40 W (tp = 100 μs), total power dissipation of 365 mW on FR4 PCB, and forward voltage ≤ 0.9 V at IF = 10 mA. Its thermal resistance from junction to ambient is 340 K/W under standard mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 37.0 V to 41.0 V at IZ = 2 mA - defines regulated output voltage range under nominal bias |
| Differential Resistance (rdif) | 350 Ω max at IZ = 2 mA - determines regulation stiffness and load-induced voltage deviation |
| Reverse Current (IR) | 0.05 μA max at VR = 39 V - ensures minimal standby power loss in high-impedance bias networks |
| Diode Capacitance (Cd) | 45 pF at f = 1 MHz, VR = 0 V - limits high-frequency noise coupling in signal path clamping |
| Power Dissipation (Ptot) | 365 mW on FR4 PCB - sets maximum continuous DC or low-duty-cycle pulsed power handling |
| Junction Temperature (Tj) | −55 °C to +150 °C - enables operation in under-hood automotive environments without derating |
| Package | DFN1006BD-2 (SOD882BD), 1.0 mm × 0.6 mm × 0.47 mm - supports automated placement and reflow with side-wettable flanks for IPC-A-610 Class 3 solder joint inspection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C39,115 | Same 39 V nominal, ±5 %, but SOT23 package (larger footprint, no side-wettable flanks); 600 Ω rdif at 5 mA | Not AEC-Q101 qualified; limited to industrial/commercial use; higher thermal resistance (500 K/W) | Select when cost sensitivity outweighs automotive qualification or space constraints are relaxed. |

FAQ
What is the Zener voltage tolerance for PZU884LS-C39-Q?
The PZU884LS-C39-Q has a nominal Zener voltage of 39 V with a tolerance of approximately ±5 %, meaning its actual breakdown voltage falls between 37.0 V and 41.0 V when tested at IZ = 2 mA and Tj = 25 °C. This tolerance band is confirmed in Table 9 of the official Nexperia datasheet Rev. 4.
Is PZU884LS-C39-Q suitable for reflow soldering with IPC-A-610 Class 3 compliance?
Yes-its DFN1006BD-2 package features side-wettable flanks (SWF), enabling automated optical inspection of solder fillets without X-ray. The recommended reflow footprint (Fig. 10) and thermal profile align with J-STD-020 moisture sensitivity level 1, supporting full IPC-A-610 Class 3 assembly validation.
How does the leakage current behavior differ between 'B' and 'C' variants in the PZU884LS-Q series?
The 'C' series-including PZU884LS-C39-Q-uses intentionally elevated leakage current (0.05 μA max at VR = 39 V) to optimize fast switching and reduce noise, per AN90031. In contrast, 'B' series parts prioritize ultra-low leakage (<0.1 μA) at lower voltages but sacrifice transient response speed.
Can PZU884LS-C39-Q replace older PZUxxLS-B39-Q in existing designs?
No direct drop-in replacement: PZU884LS-C39-Q (37–41 V, 350 Ω rdif, 0.05 μA IR) differs electrically from PZU884LS-B39-Q (38.2–39.8 V, 130 Ω rdif, 0.05 μA IR). While both are AEC-Q101 qualified, the tighter voltage band and lower dynamic impedance of the 'B' variant may affect regulation accuracy in precision applications.
