SMS7621-079LF

RF Diode Overview

The SMS7621-079LF is a surface-mountable silicon Schottky diode designed for RF and microwave mixer and detector applications. It operates at frequencies up to 24 GHz and features a low barrier voltage with tight parameter distribution. The device is housed in an SC-79 package with a series inductance of 0.7 nH. Key electrical specifications include a rated reverse voltage (VB) of 2 V, a typical junction capacitance (CT) of 0.25 pF at 0 V, and a forward voltage (VF) range of 260 mV to 320 mV at 1 mA. Maximum ratings specify a steady-state forward current of 50 mA and power dissipation of 75 mW.

RF Diode Procurement Notes

Verify the specific ordering suffix against official Skyworks documentation to confirm the exact package type and marking code. Confirm Moisture Sensitivity Level (MSL) and soldering reflow requirements before assembly. Ensure ESD handling precautions are strictly followed during storage and production to prevent device damage.

RF Diode Selection Notes

Select this component for applications requiring operation up to 24 GHz with minimal forward voltage drop. The SC-79 package is suitable for surface-mount processes. Evaluate the 0.7 nH series inductance for impedance matching in high-frequency layouts. Consider the 2 V reverse voltage rating when designing for peak signal levels.
