SZ3C82

Single Zener Diodes Overview

The Diotec Semiconductor SZ3C82 is a surface-mount Zener diode utilizing non-planar technology within the DO-213AB plastic MELF package. It provides a nominal Zener voltage range of 77 V to 88 V with a standard tolerance aligned to the E24 series (~±5%). The device supports a maximum power dissipation of 3 W at 50°C and handles a peak pulse power of 60 W for durations under 1 ms. Operating characteristics include a dynamic resistance of 30 Ω at a test current of 10 mA, a reverse leakage current of 1 µA at 61 V, and a maximum allowable Zener current of 34 mA. The junction temperature range spans from -50°C to +150°C.

Single Zener Diodes Feature Summary

• High power dissipation capability of 3 W in a compact plastic MELF form factor
• Zener voltage ratings extending up to 200 V across the product family
• Compliance with RoHS directives (excluding exemption 7a-I), REACH regulations, and conflict mineral standards

Single Zener Diodes Applications

• Voltage stabilization circuits
• Linear voltage regulators
• Overvoltage protection interfaces

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required automotive qualification level. Standard versions are commercial/industrial grade, while suffixes -Q and -AQ denote AEC-Q101 compliance or qualification respectively. Confirm the package type is DO-213AB and check datasheet footnotes regarding production date codes and reverse voltage testing criteria effective from October 2023.

Single Zener Diodes Selection Notes

Select the SZ3C82 when a stable reference voltage near 82 V is required in high-power SMD applications. Ensure the thermal design accommodates the 3 W dissipation limit using appropriate copper pad areas, as specified in the thermal resistance data. Consider the ±5% tolerance band for precision requirements and verify if automotive-grade variants are necessary for the target deployment environment.
