Product details
Overview
PDZ8.2B,115 from Nexperia is a single silicon Zener diode designed for low-power voltage regulation in space-constrained SMD applications, with a nominal Zener voltage of 8.2 V at 5 mA, ±2 % tolerance, 60 Ω maximum differential resistance at 5 mA, 0.5 μA maximum reverse current at 6.5 V, and 400 mW total power dissipation on FR4 PCB.
For engineers reviewing the PDZ8.2B,115 datasheet, PDZ8.2B,115 pinout, PDZ8.2B,115 application, or PDZ8.2B,115 equivalent, this device is selected for precision clamping, reference biasing, and overvoltage protection where tight voltage stability, low leakage, and hard breakdown knee are required in consumer, industrial, and communication power rails.
Technical Context
The PDZ8.2B,115 operates as a two-terminal voltage reference device with sharp Zener breakdown behavior at 8.02–8.36 V (IZ = 5 mA), exhibiting a temperature coefficient of +4.6 mV/K - indicating positive drift with junction temperature rise - and optimized for stable regulation under low-current conditions (IZ ≥ 0.5 mA).
Its thermal resistance from junction to ambient is 340 K/W on standard FR4 PCB, limiting continuous power handling above 25 °C per the derating curve, while its 130 K/W junction-to-solder-point resistance supports localized thermal management in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 8.02–8.36 V at IZ = 5 mA - defines precise clamping threshold for 8.2 V nominal rail protection |
| Differential Resistance (rdif) | ≤ 60 Ω at IZ = 5 mA - ensures minimal output voltage shift under load variation |
| Reverse Current (IR) | ≤ 0.5 μA at VR = 6.5 V - guarantees low standby power loss in bias networks |
| Forward Voltage (VF) | ≤ 0.9 V at IF = 10 mA - enables efficient forward conduction when used bidirectionally |
| Total Power Dissipation (Ptot) | 400 mW at Tamb ≤ 25 °C on FR4 PCB - sets maximum steady-state thermal budget |
| Thermal Resistance (Rth(j-a)) | 340 K/W - determines junction temperature rise per watt dissipated in standard layout |
| Package | SOD323 (SC-76) - 1.35 × 1.75 mm footprint ideal for high-density PCBs |
Pinout & Package
PDZ8.2B,115 is housed in a surface-mount SOD323 plastic package with two terminals: anode (A) and cathode (K). The cathode is marked by a visible bar on the device body. Mounting follows JEDEC SC-76 outline with 0.6 mm solder land width and 2.1 mm center-to-center pad spacing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; polarity-sensitive terminal defining Zener conduction direction |
| 2 (A) | Anode | Connected to ground or lower-potential rail; completes reverse-biased path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Hard breakdown knee | Sharp, well-defined Zener transition minimizes regulation uncertainty near VZ |
| Low dynamic impedance | 60 Ω at 5 mA enables stable voltage reference under varying load currents |
| Very low leakage current | 0.5 μA max at 6.5 V reduces quiescent power in battery-backed or low-power circuits |
| ±2 % voltage tolerance | Tight initial accuracy eliminates need for post-assembly trimming in most applications |
| SOD323 package compatibility | Standardized footprint supports automated placement and reflow without custom tooling |
Applications
| USB Port Overvoltage Clamp | Microcontroller Reset Circuit Reference |
|---|---|

IC Role / Device Role / Timing Role: Low-leakage Zener providing stable excitation voltage independent of supply fluctuations. Use Value: 0.5 μA max IR at 6.5 V extends battery life; 60 Ω rdif maintains <50 mV droop under 300 μA sensor load. |
Use Scenario: Protecting ADC inputs or op-amp stages from ESD-induced overvoltage in factory automation interfaces. IC Role / Device Role / Timing Role: Fast-response clamping device absorbing short-duration transients before they reach sensitive front-end circuitry.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C8V2 | Same 8.2 V nominal, ±5 % tolerance, 300 mW Ptot, SOT23 package | Higher leakage (5 μA @ 6.5 V) and looser tolerance reduce precision in reference use | Select when cost sensitivity outweighs regulation accuracy and board space permits larger SOT23 footprint |
| MMSZ5235B | 8.2 V nominal, ±5 % tolerance, 500 mW Ptot, SOD123 package | Higher power rating but 10× higher leakage (5 μA) and no hard knee specification | Prefer for higher-power clamping where thermal margin is critical and leakage is not constrained |
Compared with BZX84-C8V2 and MMSZ5235B, PDZ8.2B,115 delivers tighter voltage control (±2 % vs. ±5 %), lower leakage (0.5 μA vs. 5 μA), and sharper breakdown - making it optimal for precision biasing and low-power regulation where accuracy and efficiency are prioritized over raw power handling.

FAQ
What is the maximum reverse voltage (VR) that PDZ8.2B,115 can withstand before breakdown?
The PDZ8.2B,115 begins Zener breakdown at 8.02 V (minimum specified VZ) with test current IZ = 5 mA. Its absolute maximum non-repetitive peak reverse voltage is not defined separately; instead, the device is rated for up to 3.5 A surge current (tp = 100 μs) at VR ≈ VZ. Operation above 8.36 V continuously exceeds specification limits and risks thermal runaway.
Can PDZ8.2B,115 be used in forward-biased mode like a standard diode?
Yes - PDZ8.2B,115 exhibits typical silicon diode forward characteristics: ≤0.9 V at 10 mA and ≤1.1 V at 100 mA. It supports forward conduction in protection circuits (e.g., bidirectional TVS configurations) or as a level-shifting element, though its primary design intent remains reverse-biased Zener regulation.
How does the +4.6 mV/K temperature coefficient affect long-term voltage stability?
A +4.6 mV/K coefficient means VZ increases by ~4.6 mV per 1 K rise in junction temperature. Over a 100 °C range (−40 °C to +60 °C ambient), this introduces ~460 mV drift - mitigated by limiting power dissipation, using low-thermal-resistance layouts, or selecting complementary tempcos in reference divider networks.
Is PDZ8.2B,115 suitable for automotive applications?
No - PDZ8.2B,115 is not AEC-Q200 qualified and lacks automotive-specific testing (e.g., extended temperature cycling, humidity bias). Nexperia explicitly states non-automotive qualification in the legal disclaimers; use only in consumer, industrial, or communications equipment unless independently validated for automotive environments.
