Product details
Overview
PDZ9.1BGWJ from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and overvoltage protection at 9.1 V nominal Zener voltage (IZ = 5 mA), ±2 % tolerance (B-series), 60 Ω max differential resistance, 0.5 μA max reverse current at VR = 7.3 V, and AEC-Q101 qualified for automotive-grade reliability.
For engineers reviewing the PDZ9.1BGWJ datasheet, PDZ9.1BGWJ pinout, PDZ9.1BGWJ application, or PDZ9.1BGWJ equivalent, this device supports stable reference generation in power supply feedback loops, ESD clamp circuits, and low-power voltage monitoring where tight Zener tolerance, low thermal drift, and surface-mount compatibility are critical.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal working voltage of 9.1 V at 5 mA test current, exhibiting a temperature coefficient of +5.5 mV/K - indicating positive drift with junction temperature rise. Its differential resistance remains ≤60 Ω across operating current range, ensuring minimal dynamic impedance variation during regulation.
The device is rated for total power dissipation up to 365 mW at Tamb ≤ 25 °C on standard FR4 PCB, with non-repetitive peak reverse power handling of 40 W (tp = 100 μs). 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 | 8.85 V to 9.23 V at IZ = 5 mA - defines precise clamping threshold for 9.1 V nominal regulation |
| Tolerance | ±2 % (B-series) - enables accurate voltage reference without post-production trimming |
| Differential Resistance rdif | ≤60 Ω - ensures stable regulation under varying load currents |
| Reverse Current IR | ≤0.5 μA at VR = 7.3 V - guarantees low leakage in standby or high-impedance sensing paths |
| Temperature Coefficient SZ | +5.5 mV/K at IZ = 5 mA - quantifies predictable positive voltage drift with temperature |
| Non-repetitive Peak Current IZSM | 3.5 A (tp = 100 μs) - supports transient surge suppression in automotive load-dump scenarios |
| Forward Voltage VF | ≤0.9 V at IF = 10 mA - confirms low conduction loss when used in forward-biased ESD clamp configurations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C9V1 | Same 9.1 V nominal, ±5 % tolerance, SOT23 package, 300 mW Ptot | Higher tolerance and larger footprint; lacks AEC-Q101 qualification | Select for cost-sensitive consumer designs where ±5 % regulation is acceptable and board space permits SOT23 |
| MMSZ4687 | 9.1 V nominal, ±5 %, SOD123, 500 mW Ptot, no AEC-Q101 | Higher power rating but wider tolerance and unqualified for automotive use | Prefer for industrial power supplies requiring higher continuous dissipation without automotive compliance |
Compared with PDZ9.1BGWJ, BZX84-C9V1 trades AEC-Q101 and ±2 % tolerance for lower cost and broader availability, while MMSZ4687 offers higher 500 mW power handling but sacrifices automotive qualification and precision - making PDZ9.1BGWJ optimal for safety-critical, thermally constrained, and regulation-tight applications.

FAQ
What is the maximum continuous reverse current this Zener can handle at 9.1 V?
The PDZ9.1BGWJ is not rated for continuous reverse current at its Zener voltage - it is specified for regulation at IZ = 5 mA. Maximum continuous power dissipation is 365 mW at Tamb ≤ 25 °C, corresponding to ~40 mA at 9.1 V. Derating is required above 25 °C per the thermal resistance curve (Rth(j-a) = 340 K/W).
Does the ±2 % tolerance apply across temperature or only at 25 °C?
The ±2 % tolerance is specified at Tj = 25 °C and IZ = 5 mA. Total voltage variation over temperature includes both initial tolerance and temperature coefficient (+5.5 mV/K); full-range deviation must be calculated using SZ and operating junction temperature, not assumed constant.
Can this Zener be used in forward conduction mode for ESD protection?
Yes - the forward voltage is ≤0.9 V at 10 mA, and the device supports up to 200 mA forward current. Its low VF and AEC-Q101 qualification make it suitable for bidirectional ESD clamping when paired with another diode, though dedicated TVS devices offer faster response for IEC 61000-4-2 events.
How does the SOD123 package affect thermal performance compared to DO-35 or SOD323?
The SOD123 offers superior thermal resistance to solder point (50 K/W) versus SOD323 (~100 K/W) due to its larger cathode pad area, enabling better heat extraction in high-reliability applications. It is less thermally efficient than DO-35 axial leads but provides superior board-level integration and automated assembly compatibility.
