Product details
Overview
PZU6.2DB2,115 from Nexperia is a dual isolated general-purpose Zener diode in SOT353 (SC-88A) package, designed for precision voltage regulation and transient suppression in compact surface-mounted circuits. It delivers nominal 6.2 V Zener voltage with ±2 % tolerance, 80 Ω differential resistance at 5 mA, and 0.5 µA reverse current at 4.9 V, supporting automotive-grade power rail stabilization.
For engineers reviewing the PZU6.2DB2,115 datasheet, PZU6.2DB2,115 pinout, PZU6.2DB2,115 application, or PZU6.2DB2,115 equivalent, this device is selected for dual-rail reference generation, overvoltage clamping in sensor interfaces, and ESD-robust biasing in space-constrained industrial controllers where AEC-Q101 qualification and halogen-free packaging are required.
Technical Context
The PZU6.2DB2,115 integrates two electrically isolated Zener diodes in a single 5-pin SOT353 package, enabling independent regulation paths without shared cathode/anode nodes. Each diode exhibits a typical temperature coefficient of +2.7 mV/K and 250 mW total power dissipation under ambient conditions.
It operates across −55 °C to +150 °C ambient range with 150 °C maximum junction temperature, and supports non-repetitive 40 W surge pulses (100 µs square wave) per diode - critical for transient immunity in automotive body electronics and industrial I/O modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.06 V to 6.33 V at IZ = 5 mA - ensures stable 6.2 V reference within ±2 % tolerance for precision analog sensing. |
| Differential Resistance (rdif) | 80 Ω max at IZ = 5 mA - maintains low output impedance for minimal regulation error under load variation. |
| Reverse Current (IR) | 0.5 µA max at VR = 4.9 V - guarantees negligible leakage in standby mode for battery-powered systems. |
| Forward Voltage (VF) | 1.1 V max at IF = 100 mA - enables efficient forward conduction during polarity protection or clamping. |
| Non-repetitive Peak Power (PZSM) | 40 W per diode - withstands short-duration transients like ISO 7637-2 pulse 1/2a without degradation. |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - defines thermal derating envelope for PCB layout in confined enclosures. |
| AEC-Q101 Qualified | Validated for automotive discrete semiconductor stress testing - meets reliability requirements for under-hood ECUs and ADAS sensors. |
Pinout & Package
SOT353 (SC-88A) is a 5-lead ultra-small surface-mount plastic package measuring 2.2 mm × 1.35 mm × 0.95 mm, optimized for high-density PCB layouts and reflow soldering compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input node for first Zener path; connects to regulated rail or signal line requiring clamping. |
| 2 | Not Connected | Internally unconnected; must remain floating - no PCB trace or thermal pad connection. |
| 3 | Anode (Diode 2) | Independent input node for second Zener path; enables dual-rail referencing or bidirectional protection. |
| 4 | Cathode (Diode 2) | Output/reference node for Diode 2; ties to ground or reference plane for regulation. |
| 5 | Cathode (Diode 1) | Output/reference node for Diode 1; allows separate grounding or biasing from Diode 2. |
Key Features
| Feature | Design Value |
|---|---|
| Dual isolated Zener configuration | Enables independent voltage references or clamping on two signals without crosstalk or shared thermal path. |
| ±2 % Zener voltage tolerance (B2 series) | Reduces calibration overhead in factory programming and eliminates need for external trimming resistors. |
| AEC-Q101 qualification | Validates robustness against temperature cycling, humidity, and mechanical shock for automotive Tier-1 supply chains. |
| Halogen-free /DG variant available | Meets RoHS and ELV directives; dark-green package supports automated optical inspection (AOI) in high-volume assembly. |
| Low thermal resistance (Rth(j-a) = 455 K/W) | Permits sustained operation at elevated ambient temperatures without forced cooling in sealed enclosures. |
Applications
| Automotive Body Control Module | Industrial Sensor Signal Conditioning |

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-C6V2 | Single Zener in SOT23; no dual-isolated topology; 5 % tolerance; 400 mW Ptot | Requires two devices and extra PCB area for dual-rail use; higher voltage drift due to looser tolerance. | Select when only one regulated rail is needed and cost-per-device is prioritized over board space. |
| MMBZ5234B | Single Zener in SOT23; ±5 % tolerance; 350 mW Ptot; no AEC-Q101 qualification | Lacks automotive qualification and dual-diode integration; unsuitable for safety-critical or space-constrained designs. | Choose only for non-automotive consumer prototypes where qualification and miniaturization are not required. |
Compared with BZX84-C6V2 and MMBZ5234B, PZU6.2DB2,115 uniquely delivers dual isolated regulation in one AEC-Q101-qualified SOT353 package - reducing footprint by 40 % and eliminating inter-device thermal coupling in high-reliability applications.

FAQ
What is the maximum continuous reverse current the PZU6.2DB2,115 can sustain?
The device supports a maximum continuous forward current of 200 mA per diode, but reverse current is limited by power dissipation. At 25 °C ambient, with 250 mW total device power rating and 6.2 V Zener voltage, the sustainable DC reverse current is approximately 40 mA - assuming both diodes share thermal load equally and no additional heatsinking is applied.
Does Pin 2 require PCB connection or thermal treatment?
No - Pin 2 is internally not connected and must remain electrically floating. It should not be soldered to any trace, ground plane, or thermal pad. Leaving it unconnected prevents unintended parasitic coupling and ensures specified thermal resistance (Rth(j-a) = 455 K/W) and Zener voltage stability.
How does the +2.7 mV/K temperature coefficient impact regulation accuracy over −40 °C to +125 °C?
Over that range, the Zener voltage shifts by approximately ±227 mV (2.7 mV/K × 84 K), resulting in a total span of ~6.0 V to ~6.4 V. This is acceptable for non-precision biasing but requires firmware compensation in high-accuracy ADC references - confirmed by Figure 5 in the datasheet showing monotonic, predictable drift behavior.
Can PZU6.2DB2,115 replace PZU6.2DB2/DG in a design?
Yes - both share identical electrical specifications and SOT353 packaging. The /DG suffix denotes halogen-free construction and dark-green molding compound; the standard version uses conventional green compound. Substitution is electrically safe but may affect RoHS/ELV compliance status and AOI contrast in automated assembly lines.
