Product details
Overview
PDZ36BGW from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and overvoltage protection at nominal 36 V (±2 % tolerance), with 300 Ω maximum differential resistance at IZ = 5 mA, 0.05 μA reverse current at VR = 27 V, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the PDZ36BGW datasheet, PDZ36BGW pinout, PDZ36BGW application, or PDZ36BGW equivalent, this device supports stable reference generation in power supply feedback loops, ESD-robust I/O clamping, and transient-suppressed sensor biasing where tight voltage tolerance and low thermal drift are required.
Technical Context
This Zener operates in reverse breakdown mode with a nominal working voltage of 36 V at IZ = 5 mA, exhibiting a temperature coefficient of +33 mV/K - indicating positive drift with junction temperature rise. Its differential resistance of ≤300 Ω ensures minimal dynamic impedance variation under load changes.
The device supports non-repetitive surge handling up to 0.8 A (100 μs pulse) and maintains thermal resistance of 200 K/W from junction to solder point when mounted on FR4 PCB with 1 cm² cathode pad - enabling reliable operation in compact automotive and industrial PCB layouts.
Key Specifications

|---|---|
| Nominal Zener Voltage | 36 V ±2 % at IZ = 5 mA - enables precise 36 V reference with <±0.72 V deviation across production lot |
| Differential Resistance | ≤300 Ω at IZ = 5 mA - limits output voltage shift to <1.5 V under ±0.5 mA load current variation |
| Reverse Current | ≤0.05 μA at VR = 27 V - ensures negligible leakage in high-impedance bias networks |
| Temperature Coefficient | +33 mV/K at IZ = 5 mA - provides predictable +1.19 V drift over 36 °C ambient rise |
| Total Power Dissipation | 365 mW at Tamb ≤ 25 °C - supports continuous regulation in thermally constrained SMD footprints |
| Non-repetitive Peak Current | 0.8 A (100 μs pulse) - clamps short-duration transients without degradation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C36 | Same 36 V nominal, but ±5 % tolerance (C series) and higher 500 Ω rdif | Lower precision reference; suitable only where ±1.8 V tolerance acceptable | Select for cost-sensitive non-automotive applications where AEC-Q101 is not required |
| MMSZ5241B | 36 V nominal, ±5 %, 350 mW Ptot, no AEC-Q101 qualification | Lacks automotive qualification and exhibits higher IR (1.0 μA at 27 V) | Use in consumer-grade power supplies where leakage and qualification are secondary concerns |
Compared with BZX84-C36 and MMSZ5241B, PDZ36BGW delivers tighter voltage control, lower dynamic impedance, and verified automotive reliability - making it the preferred choice for safety-critical or high-accuracy regulation where long-term stability and thermal predictability are essential.

FAQ
What is the maximum continuous reverse current the PDZ36BGW can sustain at 25 °C?
The PDZ36BGW is rated for total power dissipation of 365 mW at Tamb ≤ 25 °C. At its nominal 36 V Zener voltage, this corresponds to a maximum continuous reverse current of approximately 10.1 mA (365 mW ÷ 36 V). Exceeding this value risks thermal runaway due to junction temperature rise beyond 150 °C.
How does the +33 mV/K temperature coefficient affect regulation accuracy over temperature?
With a +33 mV/K coefficient, the Zener voltage increases by 33 mV per Kelvin rise in junction temperature. Over a 100 K rise (e.g., from 25 °C to 125 °C), the voltage shifts +3.3 V - resulting in a final regulation point of ~39.3 V. This must be accounted for in reference-critical designs, especially where passive compensation is not used.
Is the PDZ36BGW suitable for bidirectional ESD protection?
No - PDZ36BGW is a unidirectional Zener diode configured for reverse-bias operation only. It lacks symmetrical breakdown characteristics and is not rated for IEC 61000-4-2 ESD events in either polarity. For bidirectional protection, purpose-built TVS diodes such as PESD5V0S1BA should be used instead.
What is the recommended PCB layout for optimal thermal performance?
For best thermal performance, mount PDZ36BGW on FR4 with a 1 cm² copper pad connected to the cathode terminal (Pin 1), using the reflow footprint specified in Figure 9 (sod123_fr). Avoid thermal relief spokes; use solid copper connection to minimize Rth(j-sp) and maintain junction temperature below 150 °C under full power.
