Product details
Overview
PDZ6.2BGWX from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and reference applications with nominal Zener voltage of 6.2 V at 5 mA, ±2 % tolerance (B-series), 80 Ω max differential resistance, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDZ6.2BGWX datasheet, PDZ6.2BGWX pinout, PDZ6.2BGWX application, or PDZ6.2BGWX equivalent, this device is selected for low-noise voltage clamping, overvoltage protection in power rails, and stable biasing in analog sensor interfaces where tight voltage tolerance and thermal stability are critical.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 6.06 V to 6.33 V at IZ = 5 mA, exhibiting a positive temperature coefficient of +2.7 mV/K - enabling predictable drift compensation in temperature-sensitive references. Its low reverse current (≤0.5 μA at VR = 4.96 V) supports high-impedance sensing nodes.
The device delivers 365 mW total power dissipation on standard FR4 PCB (single-sided copper, tin-plated), and withstands non-repetitive peak reverse power up to 40 W (100 μs pulse), making it suitable for transient suppression in 12 V automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.06 V to 6.33 V at IZ = 5 mA - defines precise clamping threshold for 6.2 V nominal rail regulation |
| Tolerance | ±2 % (B-series) - ensures tight binning for consistent performance across production batches |
| Differential Resistance (rdif) | ≤80 Ω - minimizes output voltage variation under load current changes |
| Reverse Current (IR) | ≤0.5 μA at VR = 4.96 V - enables ultra-low leakage in battery-backed or high-Z circuits |
| Temp. Coefficient (SZ) | +2.7 mV/K at IZ = 5 mA - provides predictable, linear voltage drift for thermal compensation design |
| Power Dissipation (Ptot) | 365 mW at Tamb ≤ 25 °C - sets continuous operating limit on standard FR4 PCB |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C6V2 | Same SOT-23 package; ±5 % tolerance; 100 Ω rdif; not AEC-Q101 qualified | Limited to commercial-grade consumer electronics; unsuitable for automotive under-hood use | Select only for cost-sensitive non-automotive designs where ±5 % tolerance is acceptable |
| MMSZ5234B | SOD-123 package; ±5 % tolerance; 130 Ω rdif; 500 mW Ptot; no AEC-Q101 status | Higher power handling but looser regulation; lacks automotive reliability validation | Prefer when higher continuous power is needed and automotive qualification is not required |
Compared with BZX84-C6V2 and MMSZ5234B, PDZ6.2BGWX offers tighter ±2 % tolerance, lower 80 Ω differential resistance, and AEC-Q101 qualification - making it the sole choice for automotive-critical voltage references where regulation accuracy and long-term reliability are mandatory.

FAQ
What is the maximum continuous reverse current this Zener can handle at 6.2 V?
The PDZ6.2BGWX is rated for a maximum continuous reverse current of 58 mA at 6.2 V, derived from its 365 mW total power dissipation rating (Ptot = VZ × IZ). This assumes ambient temperature ≤25 °C on a standard FR4 PCB with single-sided copper and tin plating. Derating applies above 25 °C per the thermal resistance curve.
Does the SOD123 package support automated optical inspection (AOI) after reflow?
Yes - the SOD123 package features a clearly marked cathode bar and consistent 3.75 mm × 2.55 mm footprint with defined solder pad geometry (per Figure 9), enabling reliable AOI detection of polarity, placement offset, and solder joint quality in high-volume SMT lines.
How does the +2.7 mV/K temperature coefficient affect long-term voltage stability?
The +2.7 mV/K coefficient means VZ increases by 2.7 mV per Kelvin rise in junction temperature. Over a −40 °C to +125 °C range (ΔT = 165 K), this yields a total drift of ~445 mV - but because the coefficient is linear and well-characterized, it allows accurate system-level compensation in closed-loop references or calibration algorithms.
Can PDZ6.2BGWX replace PDZ6.2B in existing designs?
Yes - PDZ6.2BGWX is a direct replacement for PDZ6.2B, sharing identical electrical specifications, SOD123 package dimensions, pinout, and AEC-Q101 qualification. The 'X' suffix denotes tape-and-reel packaging per EIA-481 standard, with no functional or performance difference from the base part number.
