Product details
Overview
PZU6.2B,115 from Nexperia is a general-purpose Zener voltage regulator diode in a SOD323F (SC-90) surface-mount package, delivering 6.2 V nominal regulation at 5 mA with ±5 % tolerance, 80 Ω maximum differential resistance, and 500 nA reverse current at 3 V. It operates across -65 °C to +150 °C ambient and supports automotive-grade power supply stabilization.
For engineers reviewing the PZU6.2B,115 datasheet, PZU6.2B,115 pinout, PZU6.2B,115 application, or PZU6.2B,115 equivalent, key selection criteria include Zener voltage accuracy, low dynamic impedance at low currents, AEC-Q101 qualification, thermal resistance (230 K/W junction-to-ambient on FR4), and SOD323F footprint compatibility for space-constrained PCBs.
Technical Context
The PZU6.2B,115 implements a hard-breakdown Zener junction optimized for stable reference voltage generation in low-power analog and digital supply rails. Its design targets minimal voltage drift under varying load and temperature conditions, with a temperature coefficient of +2.7 mV/K at 5 mA.
It features intentional low leakage (500 nA at VR = 3 V) and low dynamic impedance (80 Ω max at IZ = 5 mA), enabling precise regulation in feedback loops and voltage-clamping circuits without requiring external compensation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B6V2 | Same 6.2 V nominal, ±5 %, but SOD323 package (not SOD323F); 100 Ω rdif, 1 μA IR at 3 V | Higher dynamic impedance and leakage reduce regulation fidelity in low-current precision circuits | Acceptable for non-critical clamping where cost outweighs performance; not AEC-Q101 qualified |
| MMSZ4687 | 6.2 V nominal, ±5 %, SOD123 package; 100 Ω rdif, 1 μA IR at 3 V; Ptot = 500 mW | Larger footprint (3.7 × 1.6 mm) and higher thermal resistance limit use in ultra-dense layouts | Preferred when board space permits and legacy SOD123 tooling is in place; no automotive qualification |
Compared with BZX384-B6V2 and MMSZ4687, the PZU6.2B,115 delivers lower dynamic impedance, lower leakage, tighter thermal performance on FR4, and AEC-Q101 compliance-making it the optimal choice for space-constrained, automotive-grade, or precision-regulation applications where SOD323F mounting is feasible.

FAQ
What is the Zener voltage tolerance of PZU6.2B,115?
The PZU6.2B,115 has a ±5 % Zener voltage tolerance (B grade), meaning its nominal 6.2 V regulation falls between 5.89 V and 6.51 V at IZ = 5 mA. This tolerance is confirmed in Table 8 of the Nexperia datasheet and applies directly to the PZU6.2B,115 variant without interpolation or extrapolation.
Is PZU6.2B,115 qualified for automotive use?
Yes, the PZU6.2B,115 is AEC-Q101 qualified per Section 11 of the Nexperia datasheet. This qualification covers stress testing for discrete semiconductors and confirms suitability for automotive applications including under-hood and cabin modules-no additional qualification is required when using the PZU6.2B,115 in such designs.
What is the maximum power dissipation for PZU6.2B,115 on a standard FR4 PCB?
The PZU6.2B,115 delivers 550 mW total power dissipation when mounted on an FR4 PCB with single-sided copper, tin-plated, and a 1 cm² cathode pad (Table 4, Note [2]). Derating begins above 25 °C ambient, following the curve in Figure 4 of the datasheet.
How does the differential resistance of PZU6.2B,115 affect regulation accuracy?
The PZU6.2B,115 has a maximum differential resistance of 80 Ω at IZ = 5 mA (Table 8). This low rdif limits output voltage shift to ≤0.4 V for a 5 mA load change-critical for maintaining reference stability in feedback paths where the PZU6.2B,115 serves as a precision shunt element.
What package type is used for PZU6.2B,115 and how is polarity marked?
The PZU6.2B,115 uses the SOD323F (SC-90) package-a 2.7 × 1.6 mm surface-mount outline with flat leads. Polarity is indicated by a marking bar aligned with Pin 1 (cathode), as shown in Figure 9 and Table 2 of the Nexperia datasheet. This marking ensures unambiguous orientation during automated placement of the PZU6.2B,115.
