KPC357NT0C Description

Short technical summary and product information.

The KPC357NT0C is a DC-input, single-channel optocoupler from RS Components, featuring a phototransistor output. It is housed in a compact 4-pin mini-flat package with a low profile of 2.0mm, making it suitable for high-density mounting applications.

 

This optocoupler provides an input-output isolation voltage of 3750 Vrms. Key electrical characteristics include a forward voltage of typically 1.2V at 20mA, a collector-emitter voltage of up to 80V, and a collector current of up to 50mA. The current transfer ratio (CTR) is a minimum of 50% at IF=5mA and Vce=5V, with a typical CTR of 15% at IF=1mA and Vce=5V. The device also features a fast response time, with rise and fall times typically 5us and 4us respectively.

 

Designed for reliability, the KPC357NT0C operates within a temperature range of -55 to +115°C. It is Pb-free and RoHS compliant. The MSL class is 1, indicating unlimited usability under standard conditions.

 

Applications for the KPC357NT0C include hybrid substrates requiring high-density mounting, programmable controllers, DC-DC converters, and telecommunication equipment. Its robust isolation and compact form factor make it a versatile component for various electronic designs.
