SZ3C1

Single Zener Diodes Overview

The SZ3C1 is a non-planar surface-mount Zener diode manufactured by Diotec Semiconductor in the DO-213AB (MELF) plastic package. It operates as a forward-biased silicon diode with a nominal voltage of approximately 0.77 V and a test current of 100 mA. The device features a maximum power dissipation of 3 W at 50°C, a junction temperature range of -50°C to +150°C, and a storage temperature up to 175°C. Standard voltage tolerance follows the E24 series (~±5%).

Single Zener Diodes Feature Summary

• High power dissipation capability of 3 W.
• Non-planar SMD technology for robust performance.
• Compliant with RoHS, REACH, and Conflict Minerals regulations.

Single Zener Diodes Procurement Notes

Verify the specific suffix when ordering. The standard version is commercial/industrial grade. Suffixes -Q indicate AEC-Q101 compliance, while -AQ indicates AEC-Q101 qualification. Confirm these designations match project requirements before procurement.

Single Zener Diodes Selection Notes

Select this component for low-voltage stabilization where high power handling is required in a MELF package. Note that it functions primarily as a forward-biased diode; ensure circuit polarity connects the cathode (marked by a white band) to the negative pole.

Single Zener Diodes Part Context

This part belongs to the SZ3C1...SZ3C200 series of SMD Zener diodes. The series covers a wide voltage range from 1.0 V to 200 V, all utilizing the same DO-213AB case and 3 W power rating architecture.

Single Zener Diodes FAQ

How should the SZ3C1 be connected in a circuit?

It is operated in forward bias. The cathode, indicated by a white band, must be connected to the negative pole.

What does the marking 'Zxx' on the component indicate?

The marking 'Zxx' corresponds to the Zener voltage value, where 'xx' represents the specific voltage rating.
