SML4762HE3_A/I

Single Zener Diodes Overview

The SML4762HE3_A/I is a surface mount Zener diode from the SML4738 to SML4764A series, manufactured by Vishay Semiconductors. It features an 82 V nominal Zener voltage with a ±5% tolerance (suffix A). The device operates within a test current range of 2.5 to 31 mA and provides a maximum reverse leakage current of 5 µA at 75 V. It exhibits a dynamic impedance of 62.2 Ω at IZT1 and supports a surge current of 3000 mA. Rated for 1 W power dissipation at 75 °C, it utilizes the SMA (DO-214AC) package and is qualified under AEC-Q101 standards.

Single Zener Diodes Feature Summary

• AEC-Q101 qualified for automotive reliability
• Low Zener impedance and low regulation factor
• High temperature soldering guaranteed up to 260 °C
• UL 94 V-0 flammability classification

Single Zener Diodes Applications

• Surface mounted applications requiring precise voltage reference
• Automotive electronic circuits due to AEC-Q101 qualification
• Voltage regulation in high-temperature environments

Single Zener Diodes Procurement Notes

Verify that the ordering code matches the specific suffix requirements for your application. Confirm the AEC-Q101 qualification status if used in automotive contexts. Ensure the SMA (DO-214AC) package dimensions align with your PCB footprint. Check for any recent Product Change Notifications (PCN) that may affect material categorization or manufacturing location.

Single Zener Diodes Selection Notes

Select this component when a stable 82 V reference is needed in a compact surface mount format. The ±5% tolerance offers tighter control than standard variants. Consider the 1 W power rating and thermal management requirements for continuous operation. Verify compatibility with automated assembly processes given the reel packaging options.

Single Zener Diodes Part Context

This part belongs to the SML4738 to SML4764A series of surface mount Zener diodes. It shares the same SMA (DO-214AC) package and general electrical characteristics as other members of the family, differing primarily in its specific Zener voltage rating. The HE3 designation indicates RoHS compliance and AEC-Q101 qualification.
