SZ3C11

Single Zener Diodes Overview

The SZ3C11 is a surface-mount Zener diode manufactured by Diotec Semiconductor, utilizing non-planar technology within a DO-213AB (MELF) plastic package. It features a nominal Zener voltage of 11 V with a standard tolerance of ±5%, resulting in a range of 10.4 V to 11.6 V. The device supports a maximum power dissipation of 3 W at 50°C and operates within a junction temperature range of -50°C to +150°C. Electrical characteristics include a test current of 50 mA, a dynamic resistance of 4 Ohms at 1 kHz, and a maximum reverse voltage of 8 V defined at 1 µA leakage current.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix when purchasing. Suffixes such as -Q indicate AEC-Q101 compliance, while -AQ denotes AEC-Q101 qualification. Confirm that the requested variant matches the required automotive or commercial grade specifications before finalizing procurement orders to ensure alignment with project reliability standards.

Single Zener Diodes Selection Notes

Select this component for applications requiring high power handling in a compact MELF footprint. Ensure the design accounts for the 3 W power rating at 50°C ambient temperature. Verify that the 11 V breakdown voltage aligns with the target regulation level and that the ±5% tolerance meets the circuit's precision requirements without necessitating tighter grading.

Single Zener Diodes Part Context

This component belongs to the SZ3C series of SMD Zener diodes produced by Diotec Semiconductor. The series spans voltages from 1.0 V to 200 V, offering a standardized solution for various voltage reference needs. All devices share the same DO-213AB mechanical outline and utilize non-planar silicon technology to maintain consistent performance across the product line.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 11 V Zener voltage, 3 W power rating, and DO-213AB package dimensions. Verify that alternative components support the required 50 mA test current and exhibit comparable dynamic resistance values to ensure equivalent circuit behavior.
