Product details
Overview
PDZ33BGWJ from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and overvoltage protection at 33 V nominal Zener voltage (VZ = 32.15–33.79 V @ IZ = 5 mA), ±2 % tolerance (B-series), with 40 W non-repetitive peak reverse power dissipation and AEC-Q101 qualification for automotive environments.
For engineers reviewing the PDZ33BGWJ datasheet, PDZ33BGWJ pinout, PDZ33BGWJ application, or PDZ33BGWJ equivalent, this device serves as a surface-mount, thermally robust, low-capacitance (60 pF @ 1 MHz) Zener solution for stable reference and clamping in power supply feedback loops, ESD-protected I/O stages, and automotive body control modules.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled differential resistance (rdif ≤ 250 Ω @ IZ = 5 mA) and low temperature coefficient (SZ = +25.0 to +29.7 mV/K), enabling stable regulation across −55 °C to +150 °C ambient range. Its 1 cm² cathode pad thermal design supports 625 mW total power dissipation under defined PCB mounting conditions.
The device features low reverse leakage (IR ≤ 0.05 μA @ VR = 25 V), fast transient response due to minimal junction capacitance (Cd = 60 pF), and robust surge capability (IZSM = 0.9 A @ tp = 100 μs), making it suitable for both steady-state regulation and short-duration overvoltage suppression.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (nominal) | 33 V - precise DC reference voltage at 5 mA test current |
| VZ tolerance | ±2 % - ensures tight regulation band for feedback accuracy |
| rdif | ≤250 Ω - low dynamic impedance maintains stable output under load variation |
| IR @ VR = 25 V | ≤0.05 μA - negligible leakage preserves high-impedance node integrity |
| Cd @ 1 MHz | 60 pF - minimal capacitive loading on high-frequency signal paths |
| PZSM | 40 W - handles short-duration surges without failure (tp = 100 μs) |
| Tj max | 150 °C - enables operation in under-hood automotive environments |
Pinout & Package
PDZ33BGWJ uses the SOD123 surface-mount plastic package (3.75 × 2.55 × 1.3 mm), optimized for automated assembly and thermal performance on FR4 PCBs with tin-plated copper.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C33 | Same 33 V nominal, but ±5 % tolerance and no AEC-Q101 qualification; SOT23 package (higher Rth(j-a) = 340 K/W) | Limited to commercial-grade consumer electronics; unsuitable for automotive under-hood use | Select only for cost-sensitive, non-automotive designs where ±5 % VZ and lower surge rating are acceptable |
| MMSZ5257B | 33 V nominal, ±5 % tolerance, 500 mW Ptot, SOD123 package, but not AEC-Q101 qualified | Acceptable for industrial control boards with moderate temperature requirements (<125 °C) | Choose when AEC-Q101 is not required and higher continuous power (vs. PDZ33BGWJ's 365 mW) is needed |
Compared with BZX84-C33 and MMSZ5257B, PDZ33BGWJ delivers tighter tolerance, automotive qualification, and superior thermal performance on standard FR4-making it the preferred choice for safety-critical and high-reliability 33 V regulation tasks.

FAQ
What is the maximum continuous reverse power dissipation for PDZ33BGWJ at 25 °C ambient?
PDZ33BGWJ has a total power dissipation (Ptot) of 365 mW at Tamb ≤ 25 °C on a standard FR4 PCB with single-sided copper and tin plating. With an enlarged 1 cm² cathode pad, it supports up to 625 mW-confirmed in Table 5 and Table 6 of the official datasheet.
Is PDZ33BGWJ suitable for use in automotive under-hood applications?
Yes-PDZ33BGWJ is AEC-Q101 qualified and rated for junction temperatures up to 150 °C. Its thermal resistance (Rth(j-sp) = 50 K/W) and surge capability (0.9 A, 100 μs) meet requirements for engine control units, BCMs, and other under-hood systems per ISO 16750-2.
How does the temperature coefficient affect regulation accuracy over temperature?
PDZ33BGWJ exhibits a positive temperature coefficient of +25.0 to +29.7 mV/K at IZ = 5 mA. This means its Zener voltage increases ~27 mV per °C rise-enabling predictable drift compensation in closed-loop systems and supporting stable operation from −55 °C to +150 °C.
Can PDZ33BGWJ be used as a replacement for older PDZ33B series diodes?
Yes-PDZ33BGWJ is the direct successor to PDZ33B in the GW series, retaining identical electrical specifications, SOD123 package, and pinout. The 'GW' suffix denotes enhanced AEC-Q101 qualification and updated thermal characterization per Rev. 1 (2017) datasheet.
