SML4761A-E3/5A

Single Zener Diodes Overview

The SML4761A-E3/5A is a surface mount Zener diode manufactured by Vishay Semiconductors, housed in the DO-214AC (SMA) package. It provides a nominal Zener voltage of 75 V with a standard tolerance of ±5% for the 'A' suffix variant. The device operates at a test current of 3.3 mA and features a maximum dynamic resistance of 175 Ω. It supports a continuous power dissipation of 1 W at 75 °C and withstands surge currents up to 2000 mA peak. The component is rated for junction temperatures up to 150 °C and storage temperatures ranging from -65 °C to +150 °C.

Single Zener Diodes Procurement Notes

Verify the specific ordering code matches the required tape quantity and reel size. Confirm RoHS compliance status and AEC-Q101 qualification requirements against project specifications. Ensure the manufacturer designation aligns with the intended supply chain source before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 75 V reference is needed in a compact SMA surface mount footprint. Consider the ±5% voltage tolerance and 175 Ω dynamic impedance for precision requirements. Evaluate thermal management needs as power dissipation decreases above 75 °C ambient temperature.

Single Zener Diodes Part Context

This part belongs to the SML4728 to SML4764A series of 1 Watt Zener diodes. The series covers a voltage range from 3.3 V to 100 V. All devices share the same DO-214AC package and mechanical characteristics, differing primarily in their specified Zener voltage and corresponding test currents.

Single Zener Diodes Replacement Considerations

Direct replacements within the same series include SML4761A-E3/61, which shares identical electrical parameters but differs in packaging quantity per reel.
