Product details
Overview
PDZ6.2B-QF from Nexperia is a single Zener diode in SOD323 (SC-76) package, designed for precision voltage regulation at 6.2 V nominal working voltage with ±2 % tolerance, 80 Ω max differential resistance at IZ = 5 mA, and 0.5 μA max reverse current at VR = 4.96 V - used in automotive power rail clamping and low-power reference circuits.
For engineers reviewing the PDZ6.2B-QF datasheet, PDZ6.2B-QF pinout, PDZ6.2B-QF application, or PDZ6.2B-QF equivalent, this device supports AEC-Q101-compliant designs requiring stable 6.2 V regulation under low-current conditions (IZ = 0.5–5 mA), minimal temperature coefficient (+2.7 mV/K), and surface-mount compatibility on FR4 PCBs.
Technical Context
This Zener diode operates in reverse breakdown mode with a hard knee characteristic, enabling sharp regulation onset at 6.2 V. Its low dynamic impedance (80 Ω typ. at 5 mA) and sub-1 μA leakage at VR = 4.96 V support stable biasing in sensor interfaces and microcontroller reset circuits.
Thermal performance is defined by Rth(j-sp) = 130 K/W (junction-to-solder point) and Rth(j-a) = 340 K/W on standard FR4, allowing 400 mW total power dissipation at Tamb ≤ 25 °C with linear derating above that temperature.

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 6.2 V nominal, but ±5 % tolerance and 100 Ω max rdif; SOT23 package (larger footprint) | Lacks AEC-Q101 qualification; suitable for industrial, not automotive, use | Select when cost sensitivity outweighs automotive compliance and tighter regulation |
| MMSZ4687 | 6.2 V nominal, ±5 % tolerance, 100 Ω rdif, 1 μA IR at 4.96 V; SOD123 package | Higher thermal resistance (Rth(j-a) ≈ 500 K/W); limited to lower ambient temperatures | Choose for legacy board compatibility where SOD123 footprint is fixed and AEC-Q101 not required |
Compared with BZX84-C6V2 and MMSZ4687, PDZ6.2B-QF delivers tighter voltage tolerance (±2 % vs ±5 %), lower dynamic impedance (80 Ω vs ≥100 Ω), and guaranteed AEC-Q101 qualification - making it the preferred choice for automotive-grade 6.2 V regulation where precision and reliability are critical.

FAQ
What is the maximum non-repetitive peak reverse current for PDZ6.2B-QF?
The maximum non-repetitive peak reverse current (IZSM) is 5.5 A, measured at tp = 100 µs, square-wave pulse, with Tamb = 25 °C prior to surge. This rating enables robust transient suppression in automotive load-dump scenarios without permanent degradation.
How does the temperature coefficient affect regulation accuracy over temperature?
With a +2.7 mV/K temperature coefficient at IZ = 5 mA, the Zener voltage increases by approximately 270 mV over a 100 °C range (−40 °C to +60 °C). This predictable positive drift allows system-level compensation in analog sensor chains and reference buffers.
Can PDZ6.2B-QF be used in forward-bias applications?
Yes - its forward voltage is rated at 0.9 V max at IF = 10 mA, making it suitable for low-voltage clamping, polarity protection, and ESD diode stacks. However, its primary design intent and characterization are for reverse-bias Zener operation.
Is the SOD323 package compatible with standard reflow profiles?
Yes - the SOD323 package is qualified for lead-free reflow per JEDEC J-STD-020, with peak temperature up to 260 °C. Recommended solder land dimensions (0.6 mm × 0.5 mm) and stencil aperture (0.5 mm × 0.5 mm) are specified in Nexperia's SOD323 footprint guide.
