Description

The HSSR-8060 consists of a

high-voltage circuit, optically

coupled with a light emitting

diode (LED). This device is a

solid-state replacement for single-

pole, normally-open (1 Form A)

electromechanical relays used for

general purpose switching of

signals and low-power loads. The

relay turns on (contact closes)

with a minimum input current, I

of 5 mA through the input LED.

The relay turns off (contact

opens) with an input voltage, V

of 0.8 V or less. The detector

contains a high speed photosensi-

tive FET driver circuit and two

high voltage MOSFETs.

This relay’s logic level input con-

trol and very low typical output

on-resistance of 0.4

Ω makes it

suitable for both ac and dc loads.

Connection A, as shown in the

schematic, allows the relay to

switch either ac or dc loads.

Connection B, with the polarity

and pin configuration as indicated

in the schematic, allows the relay

to switch dc loads only. The

advantage of Connection B is that

the on-resistance is significantly

reduced, and the output current

capability increases by a factor of

two.

The electrical and switching char-

acteristics of the HSSR-8060 are

specified from -40

°C to +85°C.
