Product details
Overview
PZU4.7DB2,115 from Nexperia is a dual isolated Zener diode pair in SOT353 (SC-88A) package, designed for precision voltage regulation and overvoltage protection in compact DC power rails. It delivers 4.7 V nominal Zener voltage (±2 % tolerance), 800 Ω typical differential resistance at 5 mA, ≤2 µA reverse leakage at 3.7 V, −1.4 mV/K temperature coefficient, and supports 40 W non-repetitive peak reverse power dissipation - used in automotive body control modules and industrial sensor signal conditioning.
For engineers reviewing the PZU4.7DB2,115 datasheet, PZU4.7DB2,115 pinout, PZU4.7DB2,115 application, or PZU4.7DB2,115 equivalent, this page provides verified pin functions, AEC-Q101 qualification status, thermal resistance data (455 K/W junction-to-ambient), dual-diode isolation confirmation, and direct substitution guidance with real parameter-level differences.
Technical Context
The PZU4.7DB2,115 integrates two electrically isolated Zener diodes in a single 5-pin SOT353 package, enabling independent regulation or bidirectional clamping without shared cathode/anode paths. Each diode operates with tight 4.55–4.75 V working voltage range at IZ = 5 mA and exhibits low 2 µA reverse current at VR = 3.7 V.
Its −1.4 mV/K temperature coefficient ensures stable regulation across −55 °C to +150 °C ambient, while the 800 Ω differential resistance minimizes output voltage drift under load variation. The device is qualified to AEC-Q101 and rated for 250 mW total power dissipation on FR4 PCB with standard footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.55 V to 4.75 V at IZ = 5 mA - defines precise regulation point for 5 V rail stabilization |
| Differential Resistance (rdif) | 800 Ω typical at IZ = 5 mA - determines output impedance and load regulation error |
| Reverse Current (IR) | ≤2 µA at VR = 3.7 V - ensures minimal quiescent power loss below regulation threshold |
| Temperature Coefficient (SZ) | −1.4 mV/K - enables predictable VZ drift compensation in wide-temperature environments |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 µs - supports transient surge suppression in automotive load-dump scenarios |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 layout |
| Junction Temperature (Tj) | 150 °C maximum - defines upper thermal limit for reliability in sealed enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C4V7 | Single Zener in SOT23; no dual-isolation; 5 % tolerance; 600 Ω rdif | Requires two devices for dual-rail use; higher voltage drift across temperature | Select only when board space allows discrete placement and ±5 % regulation is acceptable |
| MMBZ5225B | Single Zener in SOT23; 5 % tolerance; 15 µA IR at 3.7 V; no AEC-Q101 rating | Lacks automotive qualification and dual-diode integration; higher leakage increases standby drain | Use only in cost-sensitive consumer applications where AEC-Q101 and low IR are not required |

FAQ
What is the maximum continuous power dissipation for PZU4.7DB2,115 on a standard FR4 PCB?
The PZU4.7DB2,115 has a total power dissipation limit of 250 mW at ambient temperatures ≤25 °C when mounted on an FR4 PCB with single-sided copper and standard footprint. Derating applies above 25 °C at 2.0 mW/°C based on Rth(j-a) = 455 K/W.
Is Pin 2 internally connected, and how should it be handled in PCB layout?
Pin 2 is explicitly marked "not connected" in the official Nexperia datasheet and has no internal bond wire. It must remain unconnected in circuit design; however, it may be tied to ground for mechanical stability if required by assembly process - no electrical impact results.
How does the −1.4 mV/K temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
Over −40 °C to +125 °C, the Zener voltage shifts by approximately −1.4 mV per Kelvin, resulting in a total drift of −231 mV. With nominal VZ = 4.7 V, this yields ±2.5 % variation - within specification for most automotive sensor biasing and non-critical supply monitoring.
Can PZU4.7DB2,115 replace PZU4.7DB2/DG in a RoHS-compliant design?
Yes - PZU4.7DB2,115 corresponds to the standard halogen-containing version, while PZU4.7DB2/DG is halogen-free. Both share identical electrical specs and AEC-Q101 qualification. Substitution requires verifying final product halogen content compliance per customer specifications.
