Product details
Overview
PZU884LS-B3V3-QYL from Nexperia is a leadless SOD882BD (DFN1006BD-2) Zener voltage regulator diode with nominal 3.3 V breakdown voltage, ±2 % tolerance, 95 Ω differential resistance at 5 mA, and 5 μA reverse leakage current at rated voltage - used for precision low-voltage reference and overvoltage clamping in automotive power rails and sensor interface circuits.
For engineers reviewing the PZU884LS-B3V3-QYL datasheet, PZU884LS-B3V3-QYL pinout, PZU884LS-B3V3-QYL application, or PZU884LS-B3V3-QYL equivalent, this page delivers verified package mapping, AEC-Q101 qualification status, side-wettable flank solderability data, thermal resistance (340 K/W), and exact Zener characteristics per IEC 60134 limiting values.
Technical Context
This device operates as a two-terminal shunt voltage regulator with hard breakdown knee and low dynamic impedance optimized for stable 3.3 V reference under low-current conditions (IZ = 5 mA). Its temperature coefficient is −3.5 mV/K, enabling predictable drift behavior across −55 °C to +150 °C ambient range.
The DFN1006BD-2 package features side-wettable flanks for automated optical inspection (AOI) of solder joints and supports reflow-compatible footprint per Figure 10. It is qualified to AEC-Q101 with junction temperature limit of 150 °C and non-repetitive peak reverse power dissipation of 40 W at 100 μs pulse width.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.10 V to 3.50 V at IZ = 5 mA - defines tight regulation window for 3.3 V rail stabilization |
| Differential Resistance (rdif) | 95 Ω max at IZ = 5 mA - ensures minimal output voltage shift under load variation |
| Reverse Leakage Current (IR) | 5 μA max at VR = 3.3 V - enables low-power standby operation without excessive quiescent drain |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - supports bidirectional transient suppression when used with series resistor |
| Total Power Dissipation (Ptot) | 365 mW at Tamb = 25 °C on FR4 PCB - sets maximum continuous DC power handling in standard layout |
| Junction-to-Ambient Thermal Resistance | 340 K/W - determines temperature rise under steady-state bias; requires thermal relief awareness in compact layouts |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C3V3,115 | ±5 % tolerance, 300 Ω rdif, no AEC-Q101 qualification, SOT23 package | Higher regulation error and impedance; unsuitable for automotive or precision analog use | Select only for cost-sensitive consumer applications where ±5 % tolerance and non-automotive qualification are acceptable |
| MMSZ4685T1G | ±5 % tolerance, 100 Ω rdif, AEC-Q101 qualified, SOD-123 package | Larger footprint (3.5 mm × 1.6 mm), higher thermal resistance (~400 K/W), same leakage spec | Prefer when board space permits larger package and legacy SOD-123 assembly lines are in use |
Compared with BZX84-C3V3,115 and MMSZ4685T1G, PZU884LS-B3V3-QYL delivers tighter tolerance, lower impedance, and smaller footprint - making it optimal for space-constrained automotive modules requiring high-accuracy 3.3 V clamping without thermal compromise.

FAQ
What is the maximum continuous forward current rating for PZU884LS-B3V3-QYL?
The absolute maximum forward current is 200 mA per Table 5. However, sustained operation above 10 mA is not recommended due to thermal limitations - the device is optimized for reverse-biased Zener regulation, not rectification. At 10 mA forward bias, VF remains ≤0.9 V, minimizing self-heating in bidirectional protection configurations.
Does PZU884LS-B3V3-QYL support reflow soldering with standard lead-free profiles?
Yes - the DFN1006BD-2 package is qualified for JEDEC J-STD-020-compliant lead-free reflow. Figure 10 specifies a recommended solder land pattern (1.0 mm × 0.6 mm pads with 0.3 mm solder mask opening), and side-wettable flanks enable post-reflow AOI verification of solder joint quality without x-ray inspection.
How does the temperature coefficient affect regulation accuracy over automotive temperature range?
With SZ = −3.5 mV/K, the Zener voltage shifts −0.35 V from −40 °C to +125 °C (165 K delta), resulting in ~10.6 % deviation from nominal 3.3 V. This is mitigated by design margining and is within specification for most 3.3 V rail clamping applications; precision references require additional compensation or higher-VZ devices with near-zero SZ.
Can PZU884LS-B3V3-QYL be used in parallel for higher power handling?
No - Zener diodes exhibit negative temperature coefficient and mismatched VZ tolerances, causing current hogging and thermal runaway when paralleled. For >365 mW dissipation, use a single higher-rated device or active regulation. The 40 W non-repetitive peak rating applies only to short pulses (100 μs), not DC or repetitive duty cycles.
