Measurement Instrumentation
The TOSHIBA TLP598A consists of an aluminum gallium arsenide
infrared emitting diode optically coupled to a photo-MOS FET in a six
lead plastic DIP package (DIP6).
The TLP598A is a bi-directional switch which can replace mechanical
relays in many applications.
Peak off-state voltage: 60V (min.)
On-state current: 300mA (max.) (A connection)
On-state resistance: 2 (max.) (A connection)
Isolation voltage: 2500Vrms (min.)
UL recognized: UL1577, file no. E67349
