Product details
Overview
PDZ16BGWJ from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and reference applications with nominal Zener voltage 16 V at 5 mA, ±2 % tolerance (B-series), 80 Ω max differential resistance, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDZ16BGWJ datasheet, PDZ16BGWJ pinout, PDZ16BGWJ application, or PDZ16BGWJ equivalent, this device supports stable low-power voltage clamping in ECU power rails, sensor biasing circuits, and overvoltage protection stages where tight voltage tolerance and thermal reliability under ambient extremes are required.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 15.85 V to 16.51 V at IZ = 5 mA, exhibiting a temperature coefficient of +12.0 mV/K to +12.4 mV/K - indicating positive drift with junction temperature rise. Its low reverse current (≤0.05 μA at VR = 12.0 V) ensures minimal leakage in standby regulation paths.
The device delivers non-repetitive peak reverse current capability up to 1.5 A (tp = 100 μs), supported by a PZSM rating of 40 W and total power dissipation of 365 mW at Tamb ≤ 25 °C on standard FR4 PCB. Thermal resistance from junction to solder point is 50 K/W, enabling effective heat transfer through the cathode pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.85 V to 16.51 V at IZ = 5 mA - defines precise clamping threshold for 16 V nominal rail regulation |
| Tolerance | ±2 % (B-series) - enables tighter voltage margin control vs. standard ±5 % Zeners in feedback loops |
| Differential Resistance (rdif) | ≤80 Ω - ensures low dynamic impedance for stable regulation under varying load currents |
| Reverse Current (IR) | ≤0.05 μA at VR = 12.0 V - minimizes quiescent power loss in always-on bias networks |
| Non-repetitive Peak Current (IZSM) | 1.5 A (tp = 100 μs) - provides transient surge immunity without catastrophic failure |
| Thermal Resistance (Rth(j-sp)) | 50 K/W - allows direct thermal coupling to PCB copper for improved long-term reliability at elevated ambient |
| AEC-Q101 Qualified | Yes - validated for automotive-grade temperature cycling, humidity, and mechanical stress per discrete semiconductor standard |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C16 | Same 16 V nominal, ±5 % tolerance, SOT23 package, 300 mW Ptot, no AEC-Q101 qualification | Limited to commercial-grade consumer electronics; lacks automotive thermal and reliability validation | Select when cost sensitivity outweighs automotive qualification requirements and board space permits SOT23 |
| MMSZ5245B | 16 V nominal, ±5 % tolerance, SOD123 package, 500 mW Ptot, no AEC-Q101, higher rdif (100 Ω) | Higher power dissipation but looser tolerance and unqualified for automotive use | Prefer for industrial power supplies needing higher continuous dissipation but not subject to AEC stress tests |
Compared with BZX84-C16 and MMSZ5245B, PDZ16BGWJ offers tighter ±2 % tolerance, AEC-Q101 validation, and lower dynamic impedance - making it uniquely suitable for automotive and high-accuracy reference designs where long-term parametric stability is critical.

FAQ
What is the maximum continuous power dissipation for PDZ16BGWJ at 70 °C ambient?
At Tamb = 70 °C, derated power dissipation is 245 mW, calculated using the 365 mW rating at 25 °C and thermal resistance Rth(j-a) = 340 K/W. This ensures safe operation without exceeding 150 °C maximum junction temperature under typical PCB mounting conditions.
Does PDZ16BGWJ support bidirectional transient suppression?
No - PDZ16BGWJ is a unidirectional Zener diode optimized for reverse-bias clamping only. It conducts significantly only when cathode is biased ≥16.5 V above anode. Forward conduction occurs at ~0.9 V but is not rated for surge handling or bidirectional protection.
How does the +12.4 mV/K temperature coefficient affect regulation accuracy over temperature?
The positive temperature coefficient causes VZ to increase ~12.4 mV per °C rise in junction temperature. Over a −40 °C to +125 °C range, this contributes up to ±2.05 V drift, which must be compensated in high-accuracy references using resistor networks or active correction.
Can PDZ16BGWJ replace PDZ16B in existing SOD123 footprints?
Yes - PDZ16BGWJ shares identical SOD123 mechanical dimensions, pinout, and soldering profile with PDZ16B. The "J" suffix denotes tape-and-reel packaging per JEDEC standard; electrical and thermal specifications are fully compatible.
