Product details
Overview
PZU884LS-B27-QYL from Nexperia is a leadless SOD882BD (DFN1006BD-2) Zener voltage regulator diode with nominal 27 V breakdown voltage, ±2 % tolerance, 150 °C max junction temperature, and AEC-Q101 qualification for automotive power rail stabilization and ESD-protected reference circuits.
For engineers reviewing the PZU884LS-B27-QYL datasheet, PZU884LS-B27-QYL pinout, PZU884LS-B27-QYL application, or PZU884LS-B27-QYL equivalent, key selection criteria include differential resistance (21 Ω at IZ = 5 mA), low leakage (≤0.05 μA at VR = 21.4 V), side-wettable flanks for automated optical inspection, and thermal resistance of 340 K/W on FR4.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its hard breakdown knee and low dynamic impedance ensure precise regulation at low currents (IZ = 0.5 mA to 5 mA), while intentional leakage optimization supports fast transient response in noise-sensitive automotive subsystems.
The device uses silicon planar epitaxial construction with metallization optimized for high-reliability solder joints. Side-wettable flanks enable reliable solder fillet inspection per IPC-A-610, and the DFN1006BD-2 package delivers 0.6 mm × 1.0 mm footprint with 0.47 mm height for space-constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 25.1 V to 28.9 V at IZ = 5 mA - defines regulated output voltage window for 27 V nominal rail |
| Differential Resistance (rdif) | 21 Ω max at IZ = 5 mA - ensures <100 mV output deviation over 10 mA load step |
| Reverse Current (IR) | ≤0.05 μA at VR = 21.4 V - minimizes standby power loss in always-on automotive modules |
| Power Dissipation (Ptot) | 365 mW on FR4 with 70 μm copper - supports continuous operation in ambient up to +125 °C |
| Junction Temperature (Tj) | −55 °C to +150 °C - enables deployment in engine control units and ADAS sensor nodes |
| Thermal Resistance (Rth(j-a)) | 340 K/W - determines temperature rise under steady-state bias; critical for lifetime prediction |
| Capacitance (Cd) | 73 pF at f = 1 MHz, VR = 0 V - limits high-frequency noise coupling in feedback paths |
Pinout & Package
Package: DFN1006BD-2 (SOD882BD), ultra-small leadless plastic package measuring 1.0 mm × 0.6 mm × 0.47 mm with side-wettable flanks and 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated voltage rail; marking bar identifies this terminal for automated placement verification |
| 2 (A) | Anode | Connected to ground or lower-potential node; forms reverse-biased junction for Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, humidity testing, and mechanical shock per JESD22 standards |
| Side-wettable flanks (SWF) | Enables automated optical inspection (AOI) of solder fillets without X-ray, reducing manufacturing defect escape |
| Hard breakdown knee | Sharp transition into conduction at VZ improves regulation accuracy and reduces sensitivity to current variations |
| Low leakage current | ≤0.05 μA at 80 % of VZ minimizes quiescent current in battery-backed systems and sleep-mode circuits |
| Optimized for fast switching | Controlled minor leakage rise improves transient response time during load steps in DC-DC feedback networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C27 | ±5 % tolerance, SOT23 package, 350 mW Ptot, rdif = 40 Ω | Larger footprint, higher dynamic impedance, no AEC-Q101 qualification | Acceptable for non-automotive industrial designs where cost outweighs size and reliability |
| MMSZ5252B | ±5 % tolerance, SOD-123 package, 500 mW Ptot, rdif = 35 Ω, Tj = 150 °C | Higher power rating but lacks side-wettable flanks and automotive qualification | Suitable for high-power consumer-grade regulators where board space is less constrained |
Compared with BZX84-C27 and MMSZ5252B, PZU884LS-B27-QYL offers tighter tolerance, smaller footprint, AEC-Q101 compliance, and side-wettable flanks-making it uniquely suited for space-limited, safety-critical automotive voltage references requiring AOI-compatible assembly.

FAQ
What is the maximum reverse voltage that PZU884LS-B27-QYL can withstand before breakdown?
The nominal Zener voltage is 27 V, with a guaranteed breakdown range of 25.1 V to 28.9 V at IZ = 5 mA. The device is not rated for sustained operation above VZ; its absolute maximum reverse voltage is defined by the non-repetitive peak power limit of 40 W for 100 μs pulses, not steady-state DC.
Does PZU884LS-B27-QYL require a series current-limiting resistor in all applications?
Yes - like all Zener diodes, it requires an external series resistor to set operating current within the specified 0.5 mA to 5 mA range. Without current limiting, excessive power dissipation (>365 mW) will cause thermal runaway and permanent failure, especially under high-temperature ambient conditions.
How does the side-wettable flank design impact PCB assembly yield?
Side-wettable flanks allow automated optical inspection (AOI) systems to verify solder joint integrity on the lateral edges of the DFN1006BD-2 package. This eliminates reliance on X-ray for hidden-joint validation, improving first-pass yield by >12 % in high-volume automotive SMT lines per IPC-A-610 Rev H process audits.
Can PZU884LS-B27-QYL be used in parallel for higher power handling?
No - Zener diodes exhibit parameter spread (e.g., VZ tolerance ±2 %, rdif variation), causing current imbalance when paralleled. Uneven current sharing leads to thermal runaway in the lowest-VZ unit. For higher power, select a single higher-rated device or redesign using active regulation.
