Product details
Overview
PDZ27BGWJ from Nexperia is a single Zener diode in SOD123 package, rated for 27 V nominal Zener voltage at 5 mA test current, ±2 % tolerance (B-series), 365 mW total power dissipation at 25 °C ambient, and AEC-Q101 qualified for automotive use. It provides precision voltage regulation in compact surface-mounted designs requiring stable reverse breakdown behavior under low-to-moderate current conditions.
For engineers reviewing the PDZ27BGWJ datasheet, PDZ27BGWJ pinout, PDZ27BGWJ application, or PDZ27BGWJ equivalent, this device is selected for its tight voltage tolerance, low differential resistance (73 Ω max), temperature coefficient of +23.4 mV/K at 5 mA, and robust non-repetitive surge capability (1.0 A peak reverse current).
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain a stable reference voltage across its terminals. Its 27 V nominal working voltage is specified at IZ = 5 mA with typical differential resistance of 73 Ω and maximum reverse current of 0.05 μA at VR = 21.0 V.
The device features an AEC-Q101 qualification, junction-to-ambient thermal resistance of 340 K/W (free air), and a cathode-marked SOD123 package optimized for reflow soldering on FR4 PCBs with standard footprint per Figure 9.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 26.19 V to 27.53 V at IZ = 5 mA - defines precise regulation point with ±2 % tolerance |
| Differential Resistance rdif | ≤ 73 Ω - ensures minimal voltage shift under load current variation |
| Reverse Current IR | ≤ 0.05 μA at VR = 21.0 V - guarantees low leakage in standby regulation circuits |
| Temperature Coefficient SZ | +23.4 mV/K at IZ = 5 mA - quantifies voltage drift per degree Celsius rise |
| Total Power Dissipation Ptot | 365 mW at Tamb ≤ 25 °C - sets continuous DC power limit on standard FR4 PCB |
| Non-repetitive Peak Reverse Current IZSM | 1.0 A for tp = 100 μs - supports transient overvoltage clamping without failure |
| Forward Voltage VF | ≤ 0.9 V at IF = 10 mA - enables predictable forward conduction if used bidirectionally |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C27 | Same 27 V nominal, ±5 % tolerance, SOT23 package, 300 mW Ptot | Larger package footprint; lower surge rating (0.5 A IZSM) | Select when cost sensitivity outweighs AEC-Q101 requirement and surge robustness |
| MMSZ5256B | 27 V nominal, ±5 %, SOD123 package, 500 mW Ptot, no AEC-Q101 | Higher power rating but unqualified for automotive; higher leakage (1.0 μA at 21 V) | Prefer for industrial non-automotive designs needing higher continuous dissipation |
Compared with PDZ27BGWJ, BZX84-C27 trades AEC-Q101 compliance and surge robustness for lower cost and wider availability, while MMSZ5256B offers higher steady-state power handling but lacks automotive qualification and exhibits five times higher reverse leakage.

FAQ
What is the maximum continuous reverse current the PDZ27BGWJ can sustain at 25 °C?
The PDZ27BGWJ is not rated for continuous reverse current; it operates in Zener breakdown mode with specified test current IZ = 5 mA. Its maximum continuous power dissipation is 365 mW at Tamb ≤ 25 °C, corresponding to ~13.5 mA average reverse current at 27 V. Exceeding this requires derating per thermal resistance curves.
Does the PDZ27BGWJ support bidirectional operation?
No - PDZ27BGWJ is a unidirectional Zener diode optimized for reverse-bias regulation. Its forward voltage is ≤ 0.9 V at 10 mA, but it lacks symmetrical characteristics or specifications for forward conduction use. Bidirectional protection requires dedicated TVS or dual-Zener configurations.
How does the +23.4 mV/K temperature coefficient impact circuit design?
This positive coefficient means VZ increases by 23.4 mV per °C rise in junction temperature. At 27 V nominal, a 50 °C rise adds ~1.17 V - requiring thermal management or compensation in precision references. It is advantageous for temperature-sensing applications where controlled drift is needed.
Is the SOD123 footprint compatible with automated optical inspection (AOI)?
Yes - the SOD123 package has standardized dimensions (2.80 mm × 1.70 mm) and visible cathode marking bar, making it fully compatible with industry-standard AOI systems. The recommended reflow footprint (Figure 9) includes defined solder paste and solder resist areas to ensure reliable defect detection during post-reflow inspection.
