SML4751HE3/61

Single Zener Diodes Overview

The SML4751HE3/61 is a surface mount Zener diode from Vishay General Semiconductor - Diodes Division, housed in the DO-214AC (SMA) package. It features a nominal Zener voltage of 30 V with a standard tolerance of ±10%. The device has a maximum power dissipation of 1 W at 75 °C and operates within a junction temperature range of -65 °C to +150 °C. It is AEC-Q101 qualified and RoHS-compliant.

Single Zener Diodes Feature Summary

• AEC-Q101 qualified for automotive applications
• Low Zener impedance and low regulation factor
• High temperature soldering guaranteed up to 260 °C for 10 seconds
• Plastic package with UL 94 V-0 flammability classification

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• General purpose rectification and clamping

Single Zener Diodes Procurement Notes

Verify that the ordering suffix /61 corresponds to the 1800 units per reel tape configuration as specified in the datasheet. Confirm the HE3 designation indicates AEC-Q101 qualification and RoHS compliance. Ensure the required voltage tolerance matches the standard ±10% specification unless an 'A' suffix variant is needed for ±5% tolerance.

Single Zener Diodes Selection Notes

Select this component when a 30 V Zener voltage is required in a compact SMA surface mount footprint. Consider the 1 W power dissipation capability and the specific test current requirements for your application. Verify thermal management needs against the 150 °C maximum junction temperature limit.

Single Zener Diodes Part Context

This part belongs to the SML4728 to SML4764A series of surface mount Zener diodes manufactured by Vishay Semiconductors. The series covers a wide range of nominal voltages from 3.3 V to 100 V, all utilizing the DO-214AC package. The SML4751 specifically targets the 30 V segment of this lineup.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 30 V Zener diodes in the DO-214AC package. Verify electrical parameters such as Zener voltage tolerance, dynamic impedance, and power dissipation capabilities match or exceed the original specifications.
