Product details
Overview
PDZ30BGWJ from Nexperia is a single Zener diode in SOD123 surface-mount package, designed for precision voltage regulation and reference functions at nominal 30 V (29.19–30.69 V @ IZ = 5 mA), with ±2 % tolerance (B-series), 200 mA forward current rating, and AEC-Q101 qualification for automotive environments.
For engineers reviewing the PDZ30BGWJ datasheet, PDZ30BGWJ pinout, PDZ30BGWJ application, or PDZ30BGWJ equivalent, this device serves as a stable, low-capacitance (66 pF @ 1 MHz, 0 V) voltage clamp in power supply feedback loops, overvoltage protection circuits, and ESD-tolerant bias networks where thermal resistance to solder point (Rth(j-sp) = 50 K/W) and non-repetitive surge capability (IZSM = 1.0 A, tp = 100 μs) are critical.
Technical Context
This Zener operates in reverse breakdown mode with tightly controlled differential resistance (rdif ≤ 200 Ω @ IZ = 5 mA) and low temperature coefficient (SZ = +23.0 to +26.6 mV/K), enabling stable regulation across −55 °C to +150 °C ambient range. Its cathode-anode polarity is unambiguous via the marking bar on the SOD123 body.
The device delivers 365 mW total power dissipation at Tamb ≤ 25 °C on standard FR4 PCB, with junction-to-ambient thermal resistance of 340 K/W and junction-to-solder-point resistance of 50 K/W - confirming suitability for compact, thermally constrained layouts without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 30 V (29.19–30.69 V @ IZ = 5 mA); defines precise clamping threshold in feedback or protection paths |
| Tolerance | ±2 % (B-series); ensures predictable regulation window without post-production trimming |
| Reverse Current (IR) | ≤ 0.05 μA @ VR = 23.0 V; enables ultra-low leakage in high-impedance bias/reference nodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C30 | Same 30 V nominal, ±5 % tolerance, SOT23 package, higher rdif (≥ 350 Ω) | Larger footprint not suitable for space-constrained SOD123 layouts; lower thermal performance (Rth(j-a) ≈ 450 K/W) | Select when cost priority outweighs precision and thermal efficiency |
| MMSZ5257ET1G | 30 V nominal, ±5 %, SOD123 package, but only AEC-Q200 rated (not Q101), higher IR (≤ 0.1 μA) | Not qualified for automotive powertrain or safety-critical modules requiring Q101 validation | Prefer for industrial or consumer applications where automotive qualification is unnecessary |
Compared with BZX84-C30 and MMSZ5257ET1G, PDZ30BGWJ offers tighter ±2 % tolerance, lower differential resistance, and full AEC-Q101 qualification - making it the optimal choice for automotive and high-reliability industrial regulation where voltage accuracy and thermal robustness are design-critical.

FAQ
What is the maximum non-repetitive peak reverse current for PDZ30BGWJ?
The maximum non-repetitive peak reverse current is 1.0 A at pulse duration tp = 100 μs and ambient temperature of 25 °C, as specified in Table 5 and confirmed in Figure 7 of the datasheet. This rating applies to single-event surge conditions and must not be exceeded repeatedly without derating.
Is PDZ30BGWJ suitable for use in automotive powertrain applications?
Yes - PDZ30BGWJ is fully AEC-Q101 qualified for discrete semiconductors, including stress testing for temperature cycling, humidity, and surge immunity. It is approved for use in automotive body electronics and infotainment systems; however, system-level validation is required for safety-critical powertrain subsystems per ISO 26262.
How does the temperature coefficient affect regulation accuracy over temperature?
PDZ30BGWJ exhibits a positive temperature coefficient of +23.0 to +26.6 mV/K at IZ = 5 mA, meaning its Zener voltage increases linearly with junction temperature. At 100 °C rise above 25 °C, voltage shifts by approximately +2.3–2.7 V - a factor that must be included in tolerance budgeting for wide-temperature applications.
What is the recommended PCB footprint for reliable reflow soldering?
The official SOD123 reflow footprint (Figure 9) specifies 2.36 mm pad length, 1.11 mm pad width, 0.81 mm solder mask opening, and 4.18 mm center-to-center spacing. Use tin-plated copper on FR4 with single-sided 1 oz copper; avoid thermal relief on cathode pad to maintain Rth(j-sp) = 50 K/W performance.
