Product details
Overview
PZU3.6DB2,115 from Nexperia is a dual isolated general-purpose Zener diode pair in SOT353 (SC-88A) package, designed for precision voltage regulation and overvoltage protection in compact surface-mounted circuits. It delivers nominal 3.6 V Zener voltage (±2 % tolerance), 90 Ω differential resistance at 5 mA, ≤5 µA reverse current at 2.7 V, −2.4 mV/K temperature coefficient, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PZU3.6DB2,115 datasheet, PZU3.6DB2,115 pinout, PZU3.6DB2,115 application, or PZU3.6DB2,115 equivalent, key selection criteria include dual-diode isolation, tight 2 % voltage tolerance, low thermal drift, halogen-free packaging compatibility, and suitability for space-constrained power rail clamping and reference stabilization.
Technical Context
This device integrates two electrically isolated Zener 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 3.6 V nominal breakdown voltage and matched thermal characteristics.
It supports non-repetitive surge handling up to 40 W (100 µs square wave, Tj = 25 °C), total power dissipation of 250 mW at Tamb ≤ 25 °C, and junction temperature up to 150 °C. The −2.4 mV/K temperature coefficient ensures stable regulation across automotive ambient ranges (−55 °C to +150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.55 V to 3.8 V at IZ = 5 mA - enables precise 3.6 V rail clamping with ±2 % tolerance for stable reference generation. |
| Differential Resistance (rdif) | 90 Ω max at IZ = 5 mA - ensures minimal output voltage variation under load changes in regulation circuits. |
| Reverse Current (IR) | ≤5 µA at VR = 2.7 V - guarantees low leakage during standby, critical for battery-powered systems. |
| Temperature Coefficient (SZ) | −2.4 mV/K - provides predictable, linear voltage drift for compensation-aware designs in wide-temperature environments. |
| Non-repetitive Peak Power (PZSM) | 40 W (100 µs pulse) - supports transient overvoltage suppression without device failure in ESD-prone interfaces. |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - defines continuous thermal budget for dual-diode operation on standard FR4 PCBs. |
| Junction Temperature (Tj) | 150 °C maximum - allows reliable operation in under-hood automotive modules and industrial control enclosures. |
Pinout & Package
SOT353 (SC-88A) is a 5-lead, very small surface-mounted plastic package measuring 2.2 mm × 1.35 mm × 0.9 mm, optimized for high-density PCB layouts and reflow/wave soldering per JEDEC standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input terminal for forward bias or cathode-referenced Zener operation of first diode. |
| 2 | Not Connected | No internal connection - must be left floating; no routing or grounding required. |
| 3 | Anode (Diode 2) | Independent input terminal enabling dual-rail or bidirectional clamping configuration. |
| 4 | Cathode (Diode 2) | Reference node for second diode; used with Pin 3 to form isolated 3.6 V Zener path. |
| 5 | Cathode (Diode 1) | Primary regulation reference point; commonly tied to system ground or feedback node. |
Key Features
| Feature | Design Value |
|---|---|
| Dual isolated Zener structure | Enables independent voltage regulation or bidirectional clamping without cross-coupling in shared-bias circuits. |
| ±2 % Zener voltage tolerance (B2 series) | Reduces need for post-production trimming in precision reference and feedback applications. |
| AEC-Q101 qualified | Validated for automotive-grade reliability including HTOL, temperature cycling, and ESD robustness. |
| Halogen-free / dark-green plastic package (DG variant available) | Meets RoHS and ELV compliance requirements while maintaining mechanical integrity in reflow profiles. |
| Low thermal resistance (Rth(j-a) = 455 K/W) | Supports higher sustained power in thermally constrained layouts without external heatsinking. |
Applications
| Automotive Body Control Module (BCM) | 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 |
|---|---|---|---|
| BZX384-B3V6,115 | Single Zener in SOD323; same 3.6 V/±2 % spec but no dual-isolation capability. | Requires two devices for dual-rail use; larger board area and higher assembly cost. | Select when only one regulated node is needed and space permits discrete placement. |
| PZU3.6BD,115 | Same dual-Zener function but B-series (±5 % tolerance) instead of B2-series (±2 %). | Higher voltage variation impacts precision references; unsuitable for <0.5 % accuracy systems. | Choose only for cost-sensitive non-critical clamping where tighter tolerance is unnecessary. |
Compared with PZU3.6DB2,115, BZX384-B3V6,115 lacks integrated dual isolation and increases BOM count, while PZU3.6BD,115 sacrifices 2.5× tighter voltage tolerance - making the B2 variant essential for automotive and precision analog applications demanding repeatability and thermal stability.

FAQ
What is the meaning of 'DB2' in PZU3.6DB2,115?
The 'DB2' suffix denotes dual isolated Zener diodes in the B2 tolerance series (±2 %). This distinguishes it from single-Zener variants (e.g., BZX series) and looser-tolerance dual versions (e.g., PZU3.6BD). The '115' packing code indicates 3000-unit tape-and-reel packaging with 4 mm pitch.
Can Pin 2 be grounded or left unconnected in layout?
Pin 2 is internally not connected and must remain unconnected - neither grounded nor routed. Connecting it risks unintended parasitic paths or solder bridging in fine-pitch SOT353 layouts. The datasheet explicitly states "not connected" with no alternate functions.
How does the −2.4 mV/K temperature coefficient affect regulation accuracy?
At 3.6 V nominal, −2.4 mV/K means voltage decreases by 2.4 mV per Kelvin rise. Over a 100 °C range (−40 °C to +60 °C), this causes ~240 mV shift - compensated in precision designs via matching diodes or calibration. It is lower drift than typical ±5 % Zeners, supporting tighter overall tolerance.
Is PZU3.6DB2,115 suitable for bidirectional TVS-like clamping?
No - it is not rated or characterized as a TVS device. While its 40 W surge rating supports short transients, it lacks specified clamping voltage (VC) or breakdown consistency under fast-rising ESD pulses. Use dedicated TVS arrays (e.g., PESD series) for IEC 61000-4-2 compliance.
