SML4762HE3/61

Single Zener Diodes Overview

The SML4762HE3/61 is a surface mount Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features an 82 V nominal Zener voltage with a ±5 % tolerance, as indicated by the 'A' suffix in the base part number SML4762A. The device operates within a junction temperature range of -65 °C to +150 °C and dissipates up to 1 W at 75 °C. Packaged in DO-214AC (SMA), it has a maximum reverse leakage current of 5 µA at 40 V and a dynamic impedance of 200 Ω.

Single Zener Diodes Feature Summary

• AEC-Q101 qualified for automotive reliability standards
• Low Zener impedance and low regulation factor
• High temperature soldering guaranteed at 260 °C for 10 seconds
• UL 94 V-0 flammability rating for plastic package

Single Zener Diodes Applications

• Surface mounted applications requiring voltage regulation
• Automotive electronic circuits due to AEC-Q101 qualification
• General purpose voltage reference circuits

Single Zener Diodes Procurement Notes

Verify that the ordering code matches the specific tolerance requirements, noting that the 'A' suffix denotes ±5 % voltage tolerance compared to the standard ±10 %. Confirm the suffix '/61' corresponds to the 1800 units per reel tape configuration on a 7-inch plastic reel. Ensure the HE3 designation is selected if AEC-Q101 automotive qualification is required for the application.

Single Zener Diodes Selection Notes

Select this component when a precise 82 V reference is needed in a compact SMA footprint. The HE3 variant provides enhanced reliability through AEC-Q101 qualification. Consider the 200 Ω dynamic impedance and 5 µA leakage current limits during circuit design. Verify thermal management capabilities, as power dissipation decreases linearly above 75 °C ambient temperature.

Single Zener Diodes Part Context

This device belongs to the SML4728 to SML4764A series of surface mount Zener diodes. The series covers a wide voltage range from 3.3 V to 100 V in the DO-214AC package. The SML4762 specifically targets the 82 V segment, offering standardized characteristics for voltage clamping and regulation tasks across industrial and consumer electronics.

Single Zener Diodes Replacement Considerations

Cross-reference with other Vishay SML4762 variants such as SML4762-E3/61 for commercial grade or SML4762HE3_A/H for alternative reel packaging. Verify pinout compatibility and physical dimensions against DO-214AC specifications before substitution.
