HSMP-381Z-TR1G

RF Diode Overview

The HSMP-381Z is a low distortion attenuator RF PIN diode housed in an SOD-323 surface mount package. It features a breakdown voltage of 100 V and a maximum total capacitance of 0.35 pF at 50 V reverse bias. The device operates with a forward current up to 1 A (1 µs pulse) and maintains a junction temperature rating of 150 °C. Electrical specifications include a minimum resistance of 1500 Ω at IF = 0.01 mA, and a maximum resistance of 3.0 Ω at IF = 100 mA. Typical parameters show a carrier lifetime of 1500 ns and a reverse recovery time of 300 ns.

RF Diode Procurement Notes

Verify the specific ordering suffix against official documentation before procurement. Confirm that the requested variant matches the required container type, such as tape and reel or anti-static bag options. Ensure compliance with RoHS standards and lead-free requirements specified by the manufacturer. Check for any updates regarding obsolescence status or alternative part numbers.

RF Diode Selection Notes

Select this component when low distortion and high IP3 are critical for the application. The SOD-323 package provides a smaller outline compared to SOT-23 and SOT-323, making it suitable for space-constrained designs. Verify that the 100 V breakdown voltage and 0.35 pF capacitance meet the circuit requirements.

RF Diode Part Context

The HSMP-381Z belongs to Broadcom's portfolio of RF PIN diodes designed for attenuator applications. It serves as a transition option for customers previously using SOT-23 or SOT-323 packages who require a smaller footprint. The device is manufactured by Avago Technologies, now part of Broadcom Limited.
