Product details
Overview
PZU12DB2,115 from Nexperia is a dual isolated general-purpose Zener diode in SOT353 (SC-88A) package, designed for precision voltage regulation and overvoltage protection in compact PCB layouts. It features a nominal Zener voltage of 12 V (11.74 V min / 12.24 V max at IZ = 5 mA), ±2 % tolerance (B2 series), 80 Ω typical differential resistance, 0.1 µA maximum reverse current at VR = 10 V, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PZU12DB2,115 datasheet, PZU12DB2,115 pinout, PZU12DB2,115 application, or PZU12DB2,115 equivalent, key selection criteria include dual-diode isolation, tight voltage tolerance, low leakage, thermal performance on FR4 PCBs, and compatibility with reflow/wave soldering per JEDEC J-STD-020.
Technical Context
This dual Zener device integrates two electrically isolated diodes in a single 5-pin SOT353 package-pin 1 and pin 3 are anodes for diode 1 and diode 2 respectively; pins 4 and 5 are their respective cathodes; pin 2 is unconnected. Each diode operates independently with identical 12 V nominal Zener characteristics.
It supports non-repetitive surge handling up to 40 W (tp = 100 µs, square wave), total power dissipation ≤250 mW at Tamb ≤25 °C, and junction temperature up to 150 °C. Its halogen-free variant (PZU12DB2/DG) shares identical electrical specs but uses dark-green, environmentally compliant molding compound.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 11.74 V min / 12.24 V max at IZ = 5 mA - defines stable regulation point with ±2 % tolerance |
| Differential Resistance rdif | 80 Ω typ - ensures minimal output voltage shift under load current variation |
| Reverse Current IR | 0.1 µA max at VR = 10 V - guarantees low standby power loss in sensing/bias circuits |
| Non-repetitive Peak Power PZSM | 40 W - enables transient overvoltage clamping without failure (100 µs pulse) |
| Total Power Dissipation Ptot | 250 mW at Tamb ≤25 °C - sets thermal design boundary for continuous operation on standard FR4 |
| Thermal Resistance Rth(j-a) | 500 K/W - determines junction-to-ambient temperature rise under steady-state bias |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
Pinout & Package
SOT353 (SC-88A) is a 5-lead surface-mount plastic package measuring 2.2 mm × 1.35 mm × 0.95 mm, optimized for high-density routing and automated assembly. The package uses standard 4 mm pitch tape-and-reel packing (3000 units per reel, code -115).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input terminal for first Zener diode; connects to regulated node or reference source |
| 2 | Not Connected | No internal connection; must be left floating or tied to ground only if required by board layout |
| 3 | Anode (Diode 2) | Independent input for second Zener diode; enables dual-rail or redundancy schemes |
| 4 | Cathode (Diode 2) | Output terminal for second diode; provides regulated voltage referenced to this pin |
| 5 | Cathode (Diode 1) | Output terminal for first diode; forms independent regulation path with pin 1 |
Key Features
| Feature | Design Value |
|---|---|
| Dual isolated Zener configuration | Two independent 12 V Zener diodes in one package - eliminates cross-talk and enables separate voltage references |
| ±2 % Zener voltage tolerance (B2 series) | Ensures predictable regulation across production lots without post-assembly trimming |
| Low reverse leakage (0.1 µA @ 10 V) | Minimizes quiescent current in battery-powered or low-power monitoring circuits |
| AEC-Q101 qualified | Validated for automotive under-hood environments including thermal shock and humidity testing |
| Halogen-free option (DG suffix) | Meets RoHS and ELV compliance requirements without compromising electrical performance |

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-C12LT1G | Single Zener in SOT-23; no dual configuration; 5 % tolerance; 100 Ω rdif | Requires two devices for dual-rail use; higher voltage drift under load | Select when space allows discrete placement and ±5 % regulation is acceptable |
| PZU12D2,115 | Same package and pinout; ±5 % tolerance (D2 series); 100 Ω rdif; same PZSM/Ptot | Looser voltage spec; higher leakage (1 µA @ 10 V); lower cost | Choose for non-critical regulation where cost sensitivity outweighs precision needs |
Compared with BZX84-C12LT1G and PZU12D2,115, the PZU12DB2,115 delivers tighter voltage control, lower dynamic impedance, and true dual-isolation in one footprint-critical for space-constrained automotive and industrial designs requiring matched regulation paths.

FAQ
What is the maximum continuous forward current rating for each diode in the PZU12DB2,115?
Each diode supports a maximum continuous forward current (IF) of 200 mA, as specified in the Absolute Maximum Ratings table. This rating applies under ambient conditions ≤25 °C with proper PCB thermal relief; derating is required above that temperature per the thermal resistance curve.
How does the PZU12DB2,115 perform under transient overvoltage conditions?
It handles non-repetitive peak reverse power dissipation of 40 W for pulses ≤100 µs (square wave), corresponding to a peak reverse current of 9 A at 12 V. This capability is validated per IEC 61000-4-5 surge immunity standards and enables robust clamping in automotive load-dump scenarios.
Is pin 2 internally connected, and what is its recommended PCB treatment?
No, pin 2 is not internally connected-it is a mechanical dummy lead with no semiconductor junction. Nexperia's datasheet explicitly states "not connected"; it should remain un-soldered or grounded only if needed for mechanical stability, never tied to active circuit nodes to avoid parasitic coupling.
Does the PZU12DB2,115 require special soldering profiles due to its SOT353 package?
No special profile is required beyond standard JEDEC J-STD-020 Class 3 guidelines. The SOT353 package supports both reflow (peak 260 °C) and wave soldering; Nexperia provides detailed footprint drawings (Fig 8 and Fig 9) specifying 0.50 mm solder land width and 0.60 mm center-to-center spacing for reliable joint formation.
