GLL4748A-E3/96

Single Zener Diodes Overview

The GLL4748A-E3/96 is a single-channel Zener diode manufactured by Vishay Semiconductors, housed in a plastic MELF (DO-213AB) package. It features a nominal Zener voltage of 22 V with a tight tolerance of ±5%, indicated by the 'A' suffix. The device operates at a test current of 11.5 mA and maintains a maximum DC reverse leakage current of 5 µA at 16.7 V. Dynamic impedance is specified at 23 Ω under test conditions. Rated for a maximum steady-state power dissipation of 1 W at 75 °C, it supports junction temperatures up to 150 °C and withstands peak surge currents of 750 mA.

Single Zener Diodes Feature Summary

• Glass passivated chip junction ensures stable electrical performance and long-term reliability.
• Plastic MELF package provides UL 94 V-0 flammability classification for surface-mounted applications.
• Low dynamic Zener impedance contributes to effective voltage regulation across operating ranges.

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in electronic systems
• Clamping applications within signal processing paths

Single Zener Diodes Procurement Notes

Verify the specific ordering code matches the required tolerance level, as standard variants carry a ±10% tolerance while the 'A' suffix denotes ±5%. Confirm that the reel quantity aligns with production requirements, noting that the /96 suffix corresponds to 1500 units per reel. Ensure compliance with RoHS directives and REACH regulations before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a 22 V reference with high precision is necessary. The ±5% tolerance makes it suitable for tighter circuit constraints compared to standard versions. Evaluate thermal management needs, as the 1 W rating requires adequate heat dissipation at elevated ambient temperatures. Verify that the DO-213AB footprint fits the design layout constraints.

Single Zener Diodes Part Context

This part belongs to the GLL4735 to GLL4763A series, covering a broad range of Zener voltages from 6.2 V to 91 V. All members share identical physical dimensions and mounting characteristics within the DO-213AB package. The series utilizes a consistent glass passivation process and offers both standard and precision tolerance options across the voltage spectrum.

Single Zener Diodes Replacement Considerations

GLL4748-E3/96 serves as a direct parameter-equivalent substitute if the wider ±10% voltage tolerance is acceptable for the application.
