HSMS-285x Series
Surface Mount Zero Bias Schottky Detector Diodes
Data Sheet
Description
Features
Avago’s HSMS-285x family of zero bias Schottky detector
d
iodes has been designed and optimized for use in small
signal (Pin <-20 dBm) applications at frequencies below
1.5 GHz. They are ideal for RF/ID and RF Tag applications
where primary (DC bias) power is not available.
• Surface Mount SOT-23/SOT‑143 Packages
Important Note: For detector applications with input
power levels greater than –20 dBm, use the HSMS-282x
series at frequencies below 4.0 GHz, and the HSMS-286x
series at frequencies above 4.0 GHz. The HSMS-285x
s
eries IS NOT RECOMMENDED for these higher power
level applications.
Available in various package configurations, these detector diodes provide low cost solutions to a wide variety
of design problems. Avago’s manufacturing techniques
a
ssure that when two diodes are mounted into a single
package, they are taken from adjacent sites on the wafer,
a
ssuring the highest possible degree of match.
• Miniature SOT-323 and SOT‑363 Packages
• High Detection Sensitivity:
up to 50 mV/µW at 915 MHz
• Low Flicker Noise:
-162 dBV/Hz at 100 Hz
• Low FIT (Failure in Time) Rate*
• Tape and Reel Options Available
• Matched Diodes for Consistent Performance
• Better Thermal Conductivity for Higher Power
Dissipation
• Lead-free
