Product details
Overview
PDZ3.6B,115 from Nexperia is a single silicon Zener diode optimized for low-power voltage regulation in space-constrained SMD designs, with a nominal Zener voltage of 3.60 V at 5 mA, ±2 % tolerance, 90 Ω maximum differential resistance at 5 mA, 5 μA maximum reverse leakage at 1.0 V, and −2.4 mV/K temperature coefficient. It operates within a 200 mA continuous forward current limit and delivers stable reference performance in biasing, clamping, and overvoltage protection circuits.
For engineers reviewing the PDZ3.6B,115 datasheet, PDZ3.6B,115 pinout, PDZ3.6B,115 application, or PDZ3.6B,115 equivalent, this device is selected for precision low-voltage regulation where thermal stability, low dynamic impedance, and SOD323 footprint compatibility are critical - especially in portable power management, sensor signal conditioning, and microcontroller reset circuitry.
Technical Context
This Zener diode employs a planar epitaxial silicon junction structure with hard breakdown knee characteristics, enabling sharp, repeatable reverse conduction onset at its rated working voltage. Its −2.4 mV/K temperature coefficient indicates predictable, slightly negative drift over temperature - ideal for applications requiring moderate thermal compensation without external circuitry.
Designed for surface-mount assembly on FR4 PCBs with standard tin-plated copper footprints, it exhibits Rth(j-a) = 340 K/W and Rth(j-sp) = 130 K/W, supporting reliable operation up to 150 °C junction temperature under derated power conditions (400 mW at Tamb ≤ 25 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 3.60 V to 3.85 V at IZ = 5 mA - defines precise clamping threshold for low-voltage rail stabilization |
| Differential Resistance rdif | 500 Ω @ 1 mA - ensures minimal voltage shift under small-signal load variations |
| Reverse Leakage IR | 5 μA max at VR = 1.0 V - guarantees low standby power loss in high-impedance bias networks |
| Power Dissipation Ptot | 400 mW at Tamb ≤ 25 °C - sets maximum continuous thermal budget on standard FR4 PCB |
| Forward Voltage VF | 0.9 V max at IF = 10 mA - enables efficient anode-cathode conduction during forward-biased operation |
| Temperature Coefficient SZ | −2.4 mV/K at IZ = 5 mA - provides known, linear voltage drift for predictable thermal behavior |
| Junction Temperature Tj | +150 °C max - supports operation in industrial ambient environments with appropriate derating |
Pinout & Package
PDZ3.6B,115 is housed in a compact SOD323 (SC-76) plastic surface-mount package measuring 1.8 mm × 1.35 mm × 0.95 mm, with cathode identified by a visible marking bar on the body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; reverse-biased terminal where Zener breakdown occurs |
| 2 (A) | Anode | Connected to ground or lower-potential rail; completes current path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Low dynamic impedance at low currents | 500 Ω @ 1 mA - maintains tight voltage regulation even under microampere-level load changes |
| Hard breakdown knee | Sharp, non-gradual reverse conduction onset - improves accuracy in precision reference and clamp applications |
| Small SOD323 footprint | 1.8 mm × 1.35 mm outline - enables high-density layout in wearables, IoT sensors, and miniaturized power supplies |
| ±2 % VZ tolerance | Tight initial calibration - reduces need for post-production trimming in cost-sensitive consumer electronics |
| Low leakage at low VR | 5 μA max at 1.0 V - preserves battery life in always-on monitoring circuits and low-power MCU reset paths |
Applications
| Microcontroller Reset Circuit | USB Port Overvoltage Clamp |

FAQ
What is the maximum reverse voltage this diode can withstand before breakdown?
The PDZ3.6B,115 has a nominal Zener voltage of 3.60 V to 3.85 V at 5 mA test current, and its specified working voltage range is defined only for reverse-biased operation within that band. It is not rated for blocking higher reverse voltages - sustained application above 3.85 V will cause uncontrolled conduction and potential thermal failure unless current-limited externally.
Can PDZ3.6B,115 be used in place of a 3.3 V Zener diode?
No - PDZ3.6B,115 is specified for 3.60–3.85 V regulation at 5 mA and is not interchangeable with 3.3 V parts like PDZ3.3B (3.32–3.53 V). Substituting it would raise the clamping or reference voltage by ~0.3 V, potentially violating logic-level margins or reset thresholds in 3.3 V systems.
Is this diode suitable for automotive applications?
No - the PDZ3.6B,115 is not AEC-Q200 qualified and is explicitly designated as a non-automotive product in Nexperia's documentation. It lacks extended temperature validation, enhanced robustness testing, and PPAP documentation required for under-hood or safety-critical vehicle subsystems.
How does the −2.4 mV/K temperature coefficient affect circuit performance?
This coefficient means the Zener voltage decreases by approximately 2.4 mV per degree Celsius rise in junction temperature. Over a 50 °C ambient range, VZ shifts by ~120 mV - a design consideration when referencing ADCs or comparators requiring sub-1 % accuracy; compensation may be needed in high-precision applications.
