HSMP-381C-TR2G

RF Diode Overview

The HSMP-381C-TR2G is a surface mount RF PIN diode from the Broadcom HSMP-381x series, designed for low distortion attenuator applications. It features a Series configuration housed in an SOT-323 package with a lead code of 'C'. The device has a minimum breakdown voltage (VBR) of 100 V and a maximum total capacitance (CT) of 0.35 pF at 50 V reverse bias. Electrical specifications include a typical series resistance (RS) of 53 Ω at 1 mA forward current and a reverse recovery time (Trr) of 300 ns. The component operates within a junction temperature range of -65°C to +150°C.

RF Diode Feature Summary

• Optimized for low distortion microwave frequency attenuation
• Features ultra-low parasitic inductance in the SOT-323 package
• Designed for operation at frequencies significantly higher than conventional diodes

RF Diode Applications

• Low distortion attenuating circuits
• Microwave frequency operation
• Surface mount assembly in high-frequency systems

RF Diode Procurement Notes

Verify the specific ordering suffix '-TR2G' corresponds to the tape and reel packaging containing 10,000 devices per 13-inch reel as defined in the official datasheet. Confirm that the manufacturer designation matches Broadcom Limited or Avago Technologies. Ensure the component meets RoHS compliance standards by checking the detailed documentation provided by the supplier.

RF Diode Selection Notes

Select this component when designing attenuators requiring low distortion and high-frequency performance. The Series configuration is suitable for microstrip series connections where both leads are connected together to minimize inductance. Verify that the 0.35 pF capacitance and 53 Ω series resistance meet the circuit requirements for the intended operating frequency range.

RF Diode Part Context

This part belongs to the HSMP-381x family of surface mount RF PIN diodes. The '381C' designation indicates a Series configuration in an SOT-323 package. The 'TR2G' suffix specifies the bulk tape and reel packaging option. This series is distinct from the HSMP-481x line, which offers even lower inductance variants in similar packages.
