1SS390TE61

Overview

The 1SS390TE61 is a single PIN diode manufactured by Rohm Semiconductor, designed for RF switching applications. It features a reverse voltage of 35V and a junction temperature rating of 125°C. The device exhibits a capacitance of 1.2pF at 6V reverse bias and 1MHz frequency. Its forward resistance is specified as 900 milliohms at 2mA forward current and 100MHz. The component utilizes an EMD2 package (SOD-523/SC-79) with dimensions of 1.6x0.8mm and a thickness of 0.7mm. It supports a maximum power dissipation of 150mW and operates within a storage temperature range defined by standard industrial limits.

Feature Summary

• Single PIN diode configuration optimized for RF signal routing
• Low capacitance characteristic enabling high-frequency operation
• Compact surface-mount footprint suitable for space-constrained designs

Applications

• Band switching in wireless communication devices
• RF signal path selection in mobile handsets
• Antenna tuning circuits requiring low-loss switching

Procurement Notes

Verify the specific ordering suffix TE61 against current manufacturer documentation to confirm availability status. This variant may be subject to last-time-buy notices or discontinuation. Confirm RoHS compliance and packaging type requirements with authorized distributors prior to procurement to ensure alignment with production schedules.

Selection Notes

Select this component when a single PIN diode with 35V reverse voltage capability is required. Ensure the 1.2pF capacitance meets the circuit's isolation requirements at the operating frequency. Verify that the 125°C junction temperature rating aligns with the thermal management design of the target application environment.

Part Context

The 1SS390 series represents Rohm's lineup of PIN diodes for RF switching. The 1SS390TE61 is a specific tape-and-reel variant of the base 1SS390 model. It shares electrical characteristics with other variants like the 1SS390SM but differs in packaging quantity and manufacturing lot specifications. It belongs to the broader category of discrete semiconductor RF components.

Replacement Considerations

The 1SS390SM is listed as a similar level part with the same pinout and package. Verify if the SM variant's 150°C junction temperature rating provides sufficient margin for your application. Ensure the replacement matches the EMD2 package dimensions for PCB compatibility.
