GLL4744-E3/97

Single Zener Diodes Overview

The GLL4744-E3/97 is a single Zener diode from the Vishay GLL4735 to GLL4763A series, housed in a plastic MELF (DO-213AB) package. It features a nominal Zener voltage of 15 V with a standard tolerance of ±10%. The device operates at a test current of 17 mA and exhibits a maximum dynamic impedance of 14 Ω at this current level. Maximum DC reverse leakage current is specified at 5 µA when tested at 11.4 V. The component supports a maximum steady-state power dissipation of 1 W at a terminal temperature of 75 °C, with a surge current rating of 700 mA peak.

Single Zener Diodes Feature Summary

• Glass passivated chip junction for enhanced stability
• Low Zener impedance and low regulation factor
• UL 94 V-0 flammability classification for the plastic package

Single Zener Diodes Applications

• Surface mounted applications requiring stable voltage reference
• General purpose voltage regulation circuits
• Protection against overvoltage transients

Single Zener Diodes Procurement Notes

Verify the specific suffix code on the ordering label to confirm packaging format. The /97 designation indicates a 12 mm tape on a 13-inch reel with a minimum order quantity of 5000 units per box. Confirm RoHS compliance status through official manufacturer documentation prior to final procurement decisions.

Single Zener Diodes Selection Notes

Select this component for surface mount designs requiring a 15 V reference point within the GLL4735-A family. Ensure the circuit design accommodates the 1 W power dissipation limit at elevated ambient temperatures. Verify that the required tolerance aligns with the standard ±10% specification provided in the datasheet.

Single Zener Diodes Part Context

This part belongs to the Vishay GLL4735 to GLL4763A series of Zener diodes. The series covers a wide range of nominal voltages from 6.2 V to 91 V. All devices in this lineup share the same DO-213AB MELF package dimensions and similar thermal characteristics, allowing for consistent mechanical integration across different voltage requirements.

Single Zener Diodes Replacement Considerations

GLL4744A-E3/97 offers a tighter ±5% voltage tolerance compared to the standard ±10% version.
