1SS390SMFHT2R

Overview

The 1SS390SMFHT2R is an automotive-grade PIN switching diode compliant with AEC-Q101 standards. It features a single configuration in an EMD2 (SOD-523) surface-mount package. Key electrical parameters include a reverse voltage of 35V, average rectified forward current of 100mA, and peak forward surge current of 225mA. The device exhibits low capacitance of 1.2pF at 6V reverse bias and 1MHz frequency, alongside a low RF resistance of 0.9Ω at 2mA forward current and 100MHz. Operating junction temperature reaches 150°C.

Feature Summary

• Automotive grade reliability certified under AEC-Q101 standards
• Low RF resistance suitable for high-frequency band switching applications
• Compact SOD-523 surface mount package design

Applications

• High-frequency band switching circuits
• Automotive electronic systems requiring AEC-Q101 compliance
• RF signal routing and modulation

Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel quantity of 8000 units. Ensure the package code matches the required EMD2 footprint. Confirm RoHS compliance status if environmental regulations apply to the assembly process. Cross-reference the datasheet revision date against the manufacturing batch to ensure specification consistency during procurement.

Selection Notes

Select this component when AEC-Q101 certification is mandatory for the target application. Choose based on the 35V reverse voltage limit and 100mA average current requirement. Consider the 1.2pF capacitance for high-frequency performance needs. Verify that the SOD-523 package dimensions fit the available PCB real estate constraints.

Part Context

This part belongs to Rohm Semiconductor's band switching diode series designed for VHF and UHF frequencies. It serves as the automotive-compliant variant of the standard 1SS390SM. The product line emphasizes low RF resistance and small mold type construction for efficient signal handling in compact electronic assemblies.

Replacement Considerations

The 1SS390SM is the non-automotive equivalent with identical electrical specifications but lacks AEC-Q101 certification. Verify package compatibility between EMD2 and other SOD-523 variants from different manufacturers before substitution.
