RF Diode Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm the specific -TR1G suffix indicates tape and reel packaging containing 3000 devices per 7-inch reel. Ensure storage conditions remain within the specified temperature range to maintain device integrity prior to assembly.

RF Diode Selection Notes

Select this component when a Series PIN diode configuration is required for low distortion attenuation. The SOT-323 package suits space-constrained designs. Verify that the 100 V breakdown voltage and 0.35 pF capacitance meet the specific 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 manufactured by Broadcom Limited. The series includes various configurations such as Single, Common Anode, and Common Cathode variants housed in SOT-23 and SOT-323 packages. The HSMP-381C specifically denotes the Series lead code configuration.

RF Diode Replacement Considerations

Direct substitutes within the same series include HSMP-381B (Dual Cathode) or HSMP-381E (Common Anode), provided the circuit topology accommodates the different internal pin connections. Cross-series replacements require verification of matching electrical parameters and package dimensions.
