SML4741HE3/5A

Single Zener Diodes Overview

The SML4741HE3/5A is a surface mount Zener diode manufactured by Vishay Semiconductors, housed in the DO-214AC (SMA) package. It features a nominal Zener voltage of 11 V with a standard tolerance of ±10%. The device operates at a test current of 23 mA and exhibits a maximum reverse leakage current of 5 µA at its rated voltage. Key electrical parameters include a dynamic impedance of 8.4 Ω and a surge current rating of 414 mA peak. It supports a power dissipation of 1 W at 75 °C and withstands junction temperatures up to 150 °C.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm compliance requirements. The HE3 designation indicates RoHS compliance and AEC-Q101 qualification, while the /5A suffix specifies the tape and reel quantity. Ensure the requested part matches the exact document number 85782 specifications before procurement.

Single Zener Diodes Selection Notes

Select this component when an 11 V Zener voltage is required in a compact SMA surface mount footprint. Consider the ±10% tolerance and 8.4 Ω dynamic impedance for precision requirements. Verify that the 1 W power dissipation capability aligns with the thermal management design of the target application circuit.

Single Zener Diodes Part Context

This component belongs to the SML4728 to SML4764A series of surface mount Zener diodes produced by Vishay General Semiconductor - Diodes Division. The series covers a wide range of nominal voltages from 3.3 V to 100 V within the same DO-214AC package family, allowing for standardized board layouts across different voltage requirements.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 11 V Zener diodes in the DO-214AC package. Verify that alternative parts meet the same AEC-Q101 qualification and power dissipation ratings to ensure functional equivalence in existing designs.
