S8-4148/TR7

Overview

The S8-4148/TR7 is an ESD protection diode and TVS diode array manufactured by Microchip Technology. It features four diodes configured for four lines of protection. The device supports a forward current (If) of 400 mA and has a breakdown voltage (Vbr) of 90 V. It is supplied in a reel package format.

Feature Summary

• Provides electrostatic discharge protection using a multi-line diode array configuration
• Functions as a transient voltage suppressor for sensitive circuitry
• Designed for surface mount installation

Applications

• ESD protection for data lines
• Transient voltage suppression in signal paths
• Protection of I/O interfaces against static discharge events

Procurement Notes

Verify the specific suffix TR7 against official Microchip documentation to confirm tape and reel specifications. Confirm RoHS compliance status and lead times directly with the manufacturer or authorized distributors, as availability may vary. Ensure the part number matches the exact electrical characteristics required for the design.

Selection Notes

Select this component when designing circuits requiring multi-line ESD protection with a 90 V breakdown threshold. Verify that the 400 mA forward current rating meets the operational requirements of the protected lines. Compare performance metrics against alternative TVS arrays to ensure compatibility with system voltage levels and interface standards.

Part Context

This component belongs to Microchip's family of ESD protection and TVS diodes. It serves as a discrete solution for safeguarding electronic components from voltage spikes and static discharge.
