Product details
Overview
PZU8.2DB2,115 from Nexperia is a dual isolated Zener diode pair in SOT353 (SC-88A) package, designed for precision voltage regulation and overvoltage protection in compact surface-mounted circuits. It delivers nominal 8.2 V Zener voltage with ±2 % tolerance, 60 Ω differential resistance at 5 mA, and 0.5 µA reverse current at 6.4 V, supporting automotive-grade reliability per AEC-Q101.
For engineers reviewing the PZU8.2DB2,115 datasheet, PZU8.2DB2,115 pinout, PZU8.2DB2,115 application, or PZU8.2DB2,115 equivalent, key selection criteria include dual-diode isolation, halogen-free packaging, non-repetitive 40 W surge capability, thermal resistance of 455 K/W on FR4 PCB, and suitability for low-power voltage reference and transient clamping in space-constrained designs.
Technical Context
This device 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 supports 200 mA forward current and exhibits temperature coefficient of +4.6 mV/K at 5 mA, ensuring stable reference performance across industrial temperature ranges.
The dual configuration allows use in symmetrical protection schemes or dual-rail reference generation. Its 150 °C maximum junction temperature, AEC-Q101 qualification, and 250 mW total power dissipation make it suitable for automotive body electronics and industrial sensor interfaces where reliability and board space are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 8.2 V nominal, 8.02–8.36 V range at IZ = 5 mA - enables precise 8.2 V regulation with tight tolerance for feedback loops |
| Differential Resistance (rdif) | 60 Ω max at IZ = 5 mA - ensures minimal output voltage variation under load changes |
| Reverse Current (IR) | 0.5 µA max at VR = 6.4 V - guarantees low leakage in standby or high-impedance sensing nodes |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 µs - provides robust ESD/transient suppression without external TVS |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - defines continuous thermal budget for dual-diode operation on standard FR4 |
| Temperature Coefficient (SZ) | +4.6 mV/K at IZ = 5 mA - indicates positive drift, allowing predictable compensation in temperature-critical references |
| Junction Temperature (Tj) | 150 °C max - supports operation in under-hood automotive environments and sealed industrial enclosures |
Pinout & Package
SOT353 (SC-88A) is a 5-lead, very small outline surface-mount plastic package measuring 2.2 mm × 1.35 mm × 0.95 mm, optimized for high-density PCB layouts and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Forward current entry point for first Zener; connects to regulated rail or signal line needing clamping |
| 2 | Not Connected | Internal die pad with no electrical bond - must remain unconnected on PCB to avoid parasitic coupling |
| 3 | Anode (Diode 2) | Independent anode for second Zener; enables dual-rail or complementary protection topology |
| 4 | Cathode (Diode 2) | Zener breakdown terminal for Diode 2; ties to reference voltage or ground return path |
| 5 | Cathode (Diode 1) | Zener breakdown terminal for Diode 1; electrically isolated from Pin 4 for true dual-diode operation |
Key Features
| Feature | Design Value |
|---|---|
| Dual isolated Zener structure | Enables independent regulation or clamping on two signals without shared impedance or crosstalk |

| AEC-Q101 qualified | Validated for automotive applications including body control modules and sensor signal conditioning |
| Halogen-free /DG variant available | Meets RoHS and ELV compliance requirements without compromising thermal or electrical performance |
| Small dark-green SOT353 package | Supports automated optical inspection (AOI) and reduces PCB real estate by >40% vs. SOIC-8 dual Zeners |
Applications
| Automotive Body Control Unit | Industrial Sensor Signal Conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C8V2 | Single Zener in SOT23; no dual isolation; ±5 % tolerance; 90 Ω rdif | Requires two devices for dual function; higher leakage (5 µA at 6.4 V); not AEC-Q101 qualified | Select only if dual isolation is unnecessary and cost is primary constraint |
| PZU8.2D,115 | Same dual-Zener SOT353 package but ±5 % tolerance; 80 Ω rdif; no AEC-Q101 certification | Lower precision and reliability; suitable for consumer-grade non-automotive applications | Choose when ±2 % tolerance and automotive qualification are not required |
Compared with BZX84-C8V2 and PZU8.2D,115, the PZU8.2DB2,115 uniquely delivers dual isolated Zeners with ±2 % tolerance, AEC-Q101 qualification, and 60 Ω differential resistance - making it the only option for space-constrained automotive or industrial dual-reference designs requiring guaranteed precision and reliability.

FAQ
What is the maximum continuous forward current rating for each diode in the PZU8.2DB2,115?
Each diode is rated for 200 mA continuous forward current at ambient temperatures up to 25 °C. Derating applies above this temperature per the thermal resistance curve; at 70 °C ambient, the usable forward current drops to approximately 120 mA due to junction temperature limits.
Is Pin 2 internally connected or truly floating in the SOT353 package?
Pin 2 is a true no-connect terminal - it is not bonded to any internal die structure and serves only as a mechanical alignment aid during assembly. PCB layout must leave Pin 2 unconnected to prevent unintended coupling or solder bridging that could compromise isolation between the two Zener diodes.
How does the +4.6 mV/K temperature coefficient affect regulation stability over −40 °C to +125 °C?
With +4.6 mV/K, the Zener voltage increases by ~736 mV across the full industrial range. For a nominal 8.2 V device, this yields a worst-case shift of ±368 mV around the center value. Designers must account for this in feedback networks or select complementary components to offset drift in precision references.
Can the PZU8.2DB2,115 be used for bidirectional ESD protection on a data line?
No - its dual-anode/cathode configuration (Pins 1/5 and Pins 3/4) forms two unidirectional Zeners. To achieve bidirectional clamping, external series connection (e.g., anode-to-anode or cathode-to-cathode) is required, which introduces additional parasitic inductance and compromises the 100 µs surge response specified in the datasheet.
