3 Description

The ISOS510-SP radiation-hardened device is a

single-channel, current-driven, analog isolator with

transistor output. The device offers significant

reliability and performance advantages compared to

other current-driven analog isolators, including high

bandwidth, low turn-off delay, low power consumption,

wider temperature ranges, flat current transfer ratio

(CTR), and tight process controls resulting in small

part-to-part skew. These performance advantages

stay stable across radiation, temperature, and lifetime.

ISOS510-SP is offered in small a SOIC-4 package

with 2.54mm pin pitch, supporting a 3.75kVRMS

isolation rating . The high performance and reliability

of ISOS510-SP enables these devices to be used

in aerospace and defense applications such as

feedback loops in isolated DC/DC modules, satellite

propulsion power processing units, spacecraft battery

management systems, and more.
