SMS7621-092

RF Diode Overview

The SMS7621-092 is a silicon, low-barrier n-type Schottky diode anti-parallel pair in an ultra-miniature 0201 surface-mount package. It features a breakdown voltage of 2 V and a total capacitance of 0.3 pF at 0 V reverse bias. The forward voltage ranges from 260 mV to 320 mV at 1 mA forward current, with a total resistance between 15 Ω and 18 Ω at 5 mA. Maximum dissipated power is 75 mW per junction, supporting operation up to +150 °C.

RF Diode Feature Summary

• Anti-parallel configuration designed for sub-harmonic mixer circuits and frequency multiplication
• Low barrier height produces very small forward voltage and low local oscillator power requirements
• Very low parasitic impedance with capacitance under 0.05 pF and series inductance below 0.2 nH
• Suitable for high-frequency applications up to 26 GHz or higher

RF Diode Applications

• Sub-harmonic mixer circuits
• Frequency multiplication
• Ultra-high frequency RF signal processing

RF Diode Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and material compliance. Confirm that the component meets RoHS3 standards and halogen-free requirements before integration into production. Check for any recent product change notices regarding manufacturing updates or environmental declarations.

RF Diode Selection Notes

Select this component when extremely low parasitic capacitance and inductance are critical for performance above 26 GHz. The 0201 footprint requires precise stencil aperture design and PCB layout adherence to maintain electrical characteristics. Ensure the application can accommodate the low forward voltage drop and specific thermal management needs for the 75 mW dissipation limit.

RF Diode Part Context

This device belongs to the Skyworks SMS7621 family of surface-mount Schottky diodes. While other variants like the SMS7621-040LF utilize a 0402 package, the SMS7621-092 specifically employs a smaller 0201 case size. This reduction in physical dimensions supports its design for high-volume commercial applications requiring minimal board space and superior high-frequency response.

RF Diode Replacement Considerations

Direct substitutes within the same package must be verified through official Skyworks cross-reference data. Components from other manufacturers may require re-evaluation of parasitic parameters and pin compatibility.
