Product details
Overview
PZU884LS-B47-QYL from Nexperia is a leadless SOD882BD (DFN1006BD-2) Zener voltage regulator diode with nominal 47 V breakdown voltage, ±2 % tolerance, and side-wettable flanks for automated optical inspection. It delivers 365 mW total power dissipation at 25 °C on FR4 PCB, exhibits 375 Ω differential resistance at IZ = 2 mA, and supports automotive-grade operation per AEC-Q101. It serves as a precision reference in low-power voltage regulation circuits.
For engineers reviewing the PZU884LS-B47-QYL datasheet, PZU884LS-B47-QYL pinout, PZU884LS-B47-QYL application, or PZU884LS-B47-QYL equivalent, key selection criteria include its 47 V nominal Zener voltage, ultra-small 1.0 mm × 0.6 mm footprint, side-wettable flanks for solder-joint inspection, AEC-Q101 qualification, and low leakage current optimized for noise-sensitive regulation.
Technical Context
This Zener diode operates in reverse-bias breakdown mode to maintain stable voltage across load variations. Its design targets low-current regulation (IZ = 2 mA typical), with intentional leakage current optimization for fast switching and reduced noise per AN90031 - distinguishing it from lower-voltage variants that prioritize hard knee characteristics.
The device uses silicon planar technology in a DFN1006BD-2 package with cathode-indicating marking bar and 0.65 mm pitch. Thermal resistance from junction to ambient is 340 K/W under standard FR4 mounting conditions, enabling reliable operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 46.1 V to 47.9 V at IZ = 2 mA - defines precise regulation point for mid-range high-voltage references |
| Differential Resistance rdif | 375 Ω max at IZ = 2 mA - determines output impedance and regulation sensitivity to current changes |
| Reverse Current IR | 0.05 μA max at VR = 32.9 V - ensures minimal standby power loss in battery-backed systems |
| Total Power Dissipation Ptot | 365 mW at Tamb = 25 °C on FR4 - sets maximum continuous DC power handling under standard layout |
| Junction Temperature Tj | −55 °C to +150 °C - enables deployment in under-hood automotive environments and industrial control enclosures |
| Package | DFN1006BD-2 (SOD882BD), 1.0 mm × 0.6 mm × 0.47 mm - ultra-compact, leadless, side-wettable for AOI-compatible reflow assembly |
| AEC-Q101 Qualified | Yes - validated for automotive applications including body electronics and powertrain subsystems |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a 2-terminal, leadless surface-mount plastic package with side-wettable flanks, 0.65 mm pitch, and 1.0 mm × 0.6 mm body. The marking bar identifies the cathode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; reverse-bias anode-to-cathode voltage establishes Zener conduction |

FAQ
What is the maximum non-repetitive peak reverse power dissipation for PZU884LS-B47-QYL?
The device supports 40 W non-repetitive peak reverse power dissipation (PZSM) for 100 μs square-wave pulses at Tj = 25 °C prior to surge. This rating enables robust transient overvoltage clamping in automotive load-dump and inductive switching scenarios without permanent degradation.
How does the side-wettable flank feature benefit manufacturing?
Side-wettable flanks allow automated optical inspection (AOI) systems to verify solder fillet formation on the package edges without requiring X-ray or cross-section analysis. This significantly improves first-pass yield and process control for high-volume SMT lines assembling automotive and industrial PCBs.
Is PZU884LS-B47-QYL suitable for use in 48 V battery systems?
Yes - its 47 V nominal Zener voltage, 150 °C maximum junction temperature, and AEC-Q101 qualification make it appropriate for voltage monitoring, clamping, and reference functions in 48 V mild-hybrid automotive systems and industrial 48 V DC distribution networks.
What is the forward voltage specification at 10 mA?
The forward voltage (VF) is guaranteed ≤ 0.9 V at IF = 10 mA under pulse test conditions (tp ≤ 300 μs, duty cycle ≤ 0.02). This ensures predictable behavior during forward-bias testing and aids in functional verification during production test.
