HSMP-3822-TR1G

RF Diode Overview

The HSMP-3822-TR1G is a surface mount RF PIN diode from the Broadcom HSMP-382x series, designed for switching applications requiring ultra-low resistance. It features a Series configuration housed in an SOT-23 package with lead code F2. Key electrical specifications include a breakdown voltage of 50 V, a maximum series resistance of 0.6 Ω at 100 MHz, and a total capacitance of 0.8 pF at 1 MHz. Typical parameters at 25°C indicate a carrier lifetime of 70 ns and a reverse recovery time of 7 ns. The device supports a forward current of 1 A (1 μs pulse) and operates within a temperature range of -65°C to +150°C.

RF Diode Procurement Notes

Verify the specific ordering suffix TR1G corresponds to tape and reel packaging containing 3000 devices per 7-inch reel. Confirm that the component meets RoHS requirements and lead-free assembly standards before integration. Ensure compatibility with standard IR reflow profiles not exceeding 260°C peak temperature during manufacturing processes.

RF Diode Selection Notes

Select this component when ultra-low series resistance is critical for switching performance. The Series configuration allows for flexible biasing arrangements in microstrip or coplanar waveguide layouts. Consider the 0.8 pF capacitance limit for high-frequency signal integrity. Verify thermal management capabilities given the junction temperature rating of 150°C.

RF Diode Part Context

This part belongs to the HSMP-382x family of surface mount RF PIN diodes manufactured by Broadcom Limited. The series includes single, dual anode, common anode, and common cathode variants. These diodes are specifically engineered for high-frequency RF applications where low parasitic inductance and capacitance are essential for optimal signal transmission and switching speed.

RF Diode Replacement Considerations

Direct substitutes within the same series include HSMP-3820 (Single), HSMP-3823 (Common Anode), and HSMP-3824 (Common Cathode). For low inductance requirements, consider the HSMP-482x series. Ensure any replacement matches the SOT-23 package dimensions and electrical characteristics such as breakdown voltage and series resistance.
