Overview
The Rohm Semiconductor 1SS356TW11 is a standard single RF diode housed in a UMD2 (SOD-323FL) surface-mount package. It features a maximum reverse voltage of 35V and a maximum forward current of 100 mA, with a power dissipation rating of 200 mW. Key electrical parameters include a capacitance of 1.2 pF at 6V reverse bias and 1 MHz frequency, and a resistance of 900 milliohms at 2 mA forward current and 100 MHz frequency. The device operates at a junction temperature up to 125°C and complies with RoHS3 standards.
Feature Summary
- Standard single configuration designed for RF applications
- Compact SOD-323FL surface-mount packaging for space-constrained designs
- Low capacitance characteristics suitable for high-frequency signal processing
Applications
- RF band switching circuits
- Signal routing in communication equipment
- High-frequency switching applications
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required tape-and-reel quantity. Check for end-of-life status as this model may be restricted from new designs. Ensure storage conditions align with moisture sensitivity level requirements before assembly.
Selection Notes
Select this component when a low-capacitance RF switch diode is required in a small footprint. Compare against alternatives like the 1SS356VM if higher junction temperature ratings are needed. Verify that the 35V reverse voltage and 100mA current limits meet circuit demands. Consider package compatibility during PCB layout design.
Part Context
This part belongs to the 1SS356 series of RF diodes manufactured by Rohm Semiconductor. It shares core specifications with variants such as the 1SS356VM but differs in supply status and specific grading. The UMD2 package provides a standardized form factor for automated surface-mount assembly processes.
Replacement Considerations
The 1SS356VMTE-17 is a confirmed substitute offering identical pinout and package dimensions. Verify functional equivalence regarding capacitance and voltage ratings before implementation.
