Product details
Overview
PDZ5.6BGWX from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and reference applications at nominal 5.6 V with ±2 % tolerance (B-series), 100 Ω max differential resistance at IZ = 5 mA, 1 μA max reverse current at VR = 4.5 V, and AEC-Q101 qualification for automotive environments.
For engineers reviewing the PDZ5.6BGWX datasheet, PDZ5.6BGWX pinout, PDZ5.6BGWX application, or PDZ5.6BGWX equivalent, this device supports stable low-power voltage clamping, ESD-robust signal line protection, and temperature-stable reference generation where tight VZ tolerance and low thermal drift are required.
Technical Context
This Zener operates in reverse breakdown mode with a nominal working voltage of 5.6 V at IZ = 5 mA, exhibiting a positive temperature coefficient of +1.9 mV/K - enabling predictable thermal behavior in bias networks. Its differential resistance remains ≤100 Ω across rated current, ensuring minimal dynamic impedance variation under load transients.
The device delivers 365 mW total power dissipation on standard FR4 PCB (single-sided copper, tin-plated) and withstands non-repetitive peak reverse power up to 40 W (tp = 100 μs), supporting surge immunity in power rail conditioning circuits without external limiting resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Differential Resistance | ≤100 Ω at IZ = 5 mA; ensures stable regulation under varying load currents. |
| Reverse Current | ≤1 μA at VR = 4.5 V; minimizes standby power loss in always-on monitoring circuits. |
| Temperature Coefficient | +1.9 mV/K at IZ = 5 mA; provides predictable, linear VZ drift over temperature for compensated designs. |
| Total Power Dissipation | 365 mW at Tamb ≤ 25 °C on standard FR4 PCB; defines continuous thermal operating envelope. |
| Non-repetitive Peak Power | 40 W for tp = 100 μs; supports transient overvoltage suppression without failure. |

Applications
| Automotive Sensor Reference | Industrial Analog Input Protection |
|---|---|
Use Scenario: Providing stable 5.6 V reference for analog-to-digital conversion in engine control unit (ECU) temperature sensors. IC Role / Device Role / Timing Role: Zener diode acts as shunt voltage reference for ADC bias network, maintaining accuracy across −40 °C to +125 °C ambient. Use Value: ±2 % VZ tolerance and +1.9 mV/K TC ensure <±30 mV total drift over full automotive temperature range, eliminating software compensation. |
Use Scenario: Clamping 0–10 V analog input signals entering PLC modules exposed to field wiring transients. IC Role / Device Role / Timing Role: Shunt limiter placed before op-amp input stage to absorb induced surges while preserving signal integrity. Use Value: 40 W non-repetitive peak power rating absorbs 1 kV/500 A surge events per IEC 61000-4-5 Level 4 without degradation. |
| Low-Power IoT Voltage Monitor | USB Port Overvoltage Clamp |
Use Scenario: Monitoring coin-cell voltage in wireless sensor tags using comparator-based brown-out detection. IC Role / Device Role / Timing Role: Zener establishes precise threshold voltage for comparator input, triggered when supply drops below 5.6 V. Use Value: 1 μA reverse leakage at 4.5 V ensures <50 nA total current draw from 3 V coin cell, extending battery life beyond 10 years. |
Use Scenario: Protecting USB 2.0 data lines (D+/D−) from ESD and hot-plug overshoot in portable docking stations. IC Role / Device Role / Timing Role: Bidirectional clamp formed by back-to-back Zeners (with complementary polarity device) referenced to 5.6 V. Use Value: Low 100 Ω differential resistance limits clamping voltage excursion to <0.5 V above VZ, preserving signal eye diagram integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V6 | Same 5.6 V nominal, ±5 % tolerance, SOT23 package, 300 mW Ptot, no AEC-Q101 qualification. | Lacks automotive qualification and tighter tolerance; suitable only for commercial-grade consumer electronics. | Select when cost sensitivity outweighs automotive compliance and precision requirements. |
| MMSZ5232BS | 5.6 V nominal, ±5 % tolerance, SOD123 package, 500 mW Ptot, not AEC-Q101 qualified. | Higher power rating but looser tolerance and unqualified for automotive; thermal performance differs due to different die construction. | Prefer when higher continuous dissipation is needed but automotive reliability is not required. |
Compared with BZX84-C5V6 and MMSZ5232BS, PDZ5.6BGWX offers superior voltage accuracy (±2 % vs. ±5 %), guaranteed automotive qualification, and optimized surge robustness - making it the sole choice for safety-critical or temperature-stable reference designs.

FAQ
What is the maximum continuous reverse current the PDZ5.6BGWX can sustain at 25 °C?
The PDZ5.6BGWX sustains a maximum continuous reverse current of 200 mA, derived from its 365 mW total power dissipation limit and 5.6 V nominal Zener voltage (Ptot/VZ ≈ 65 mA typical, but absolute maximum IF rating is 200 mA per limiting values table). This rating assumes proper PCB thermal design per Nexperia's SOD123 mounting recommendations.
Does PDZ5.6BGWX support bidirectional ESD protection?
No - PDZ5.6BGWX is a unidirectional Zener diode configured for reverse-bias operation only. For bidirectional ESD protection, two PDZ5.6BGWX devices must be connected anode-to-anode (back-to-back), or a dedicated TVS array such as PESD5V0S1BA should be used instead.
How does the +1.9 mV/K temperature coefficient affect circuit stability?
The +1.9 mV/K coefficient means VZ increases by 1.9 mV per Kelvin rise in junction temperature. Over a 100 K range (−40 °C to +60 °C), this yields ~200 mV shift - acceptable in non-critical references but requires compensation in precision ADC references. Its predictability enables first-order correction in firmware or analog compensation networks.
Can PDZ5.6BGWX replace older PDZ5.6B in existing designs?
Yes - PDZ5.6BGWX is a direct replacement for PDZ5.6B with identical electrical specifications, SOD123 package, pinout, and AEC-Q101 qualification. The "X" suffix denotes tape-and-reel packaging per latest ordering conventions; all electrical and thermal characteristics match the legacy part.
