HSMS-2852-TR2G

RF Diode Overview

The HSMS-2852-TR2G is a surface mount zero bias Schottky detector diode from the Broadcom HSMS-285x series, housed in an SOT-323 (SC-70) package. It features a series pair configuration with a maximum peak inverse voltage of 2.0 V and a typical forward voltage of 150 mV at 0.1 mA. The device exhibits a maximum reverse leakage current of 250 µA at 2 V and a typical junction capacitance of 0.30 pF at -0.5 V to -1.0 V. Designed for small signal applications below 1.5 GHz, it offers high detection sensitivity up to 50 mV/µW at 915 MHz and low flicker noise of -162 dBV/Hz at 100 Hz.

RF Diode Feature Summary

• Optimized for small signal detection in RFID and RF tag applications without primary DC bias power
• Provides matched diodes within the package for consistent performance and higher voltage sensitivity
• Features low flicker noise characteristics suitable for crystal video receivers
• Utilizes miniature surface mount packages for improved thermal conductivity

RF Diode Applications

• Zero bias microwave detector applications
• Small signal mixing and sampling circuits below 1.5 GHz

RF Diode Procurement Notes

Verify the specific ordering suffix TR2G indicates a 10,000-unit tape and reel quantity on a 13-inch reel. Confirm the component is lead-free compliant. Ensure the source documentation matches the manufacturer's official datasheet for the HSMS-285x series to validate electrical parameters and package dimensions before procurement.

RF Diode Selection Notes

Select this component for designs requiring zero bias detection at frequencies under 1.5 GHz with input power levels below -20 dBm. For higher input power applications exceeding -20 dBm, consider the HSMS-282x or HSMS-286x series instead. The series pair configuration allows for voltage doubler circuits to enhance overall sensitivity compared to single diode detectors.

RF Diode Part Context

This part belongs to the HSMS-285x family of surface mount zero bias Schottky detector diodes originally developed by Agilent and now manufactured by Broadcom Limited. The series includes various configurations such as single, bridge, and trio diodes in SOT-23, SOT-143, SOT-323, and SOT-363 packages. The HSMS-2852 specifically provides a series pair arrangement optimized for matched performance in compact designs.

RF Diode Replacement Considerations

HSMS-2852-BLK is available in a bulk antistatic bag packaging option. Other variants in the HSMS-285x series include HSMS-2850 (single), HSMS-285C (series pair), and HSMS-285P (bridge quad). Verify pinout compatibility when substituting between different package types like SOT-23 and SOT-323.
