1SS356VMFHTE-17

Overview

The 1SS356VMFHTE-17 is a band switching diode manufactured by ROHM Semiconductor, designed for high-reliability applications. It features a single configuration within an SOD-323FL (SC-90A) surface-mount package. Key electrical parameters include a peak reverse voltage of 35 V and a forward current rating of 100 mA. The device exhibits a maximum junction temperature of +150 °C and a low maximum diode capacitance of 1.2 pF at 6 V reverse bias and 1 MHz frequency. Reverse leakage current is specified at 10 nA, with a forward voltage drop of 1 V. The component supports RF operation up to 100 MHz at 2 mA forward current, offering an RF resistance of 0.9 Ω.

Feature Summary

• Automotive-grade reliability compliant with AEC-Q101 standards
• Compact SOD-323FL surface-mount package for space-constrained designs
• Low capacitance characteristics suitable for high-frequency band switching

Applications

• Antenna switch circuits in automotive infotainment systems
• Attenuator modules requiring low insertion loss
• High-frequency signal routing in communication equipment

Procurement Notes

Verify the specific ordering suffix TE-17 to confirm reel packaging quantities and tape specifications. Ensure compatibility with existing BOM requirements for AEC-Q101 qualified components. Cross-reference the manufacturer part number against official ROHM databases to confirm current production status and availability constraints before finalizing procurement plans.

Selection Notes

Select this component when designing circuits requiring AEC-Q101 compliance for automotive environments. The SOD-323FL package is appropriate for automated surface-mount assembly processes. Consider the 1.2 pF capacitance limit for high-frequency signal integrity requirements. Verify that the 35 V reverse voltage rating exceeds the maximum expected circuit operating voltages under all conditions.

Part Context

This part belongs to the 1SS356 series of band switching diodes from ROHM. It serves as an automotive-grade variant, distinguished by the VMFH suffix indicating AEC-Q101 qualification. It replaces older non-automotive versions like the standard 1SS356 while maintaining pinout compatibility. The TE-17 suffix denotes the specific taping and reel packaging format used for high-volume manufacturing.

Replacement Considerations

The 1SS356VM is a direct functional equivalent with identical pinout and package dimensions. For automotive applications, the 1SS356VMFH is the primary alternative. Standard industrial grades such as the 1SS356 are not recommended for new automotive designs due to lack of AEC-Q101 certification.
