GENERAL
Recently, optocouplers have been supplanting relays and pulse transformers for complete noise elimination, level conversion,
and high-potential isolation. Microprocessor systems are requiring more and more optocouplers on the limited area of PC boards
for I/O interface and other purposes. For these requirements, NEC has manufactured multi-channel optocouplers having 4 pins
(for one channel) to 16 pins (for four channels). These multi-channel optocouplers are called the PS2500 series optocouplers.
The PS2500 series optocouplers are divided into PS2501, PS2502, PS2505, and PS2506 according to their functions.
(PS2501L, PS2502L, PS2505L, and PS2506L have leads formed for surface installation.)
This manual describes features, structures, and basic characteristics of the PS2500 series optocouplers.
FEATURES, STRUCTURES, AND PACKAGE DIMENSIONS
Features
The major feature of PS2500 is very high isolation voltage between input and output (substantially two to three times that of the
conventional PS2400 series optocouplers). This can be proved because none of the 1300 test optocouplers were destroyed in a
strict product test (applying 10 kVac to each optocoupler for one minute). The improvement in dielectric strength of the PS2500
optocouplers has been accomplished by the double molding package structure.
In addition to high isolation voltage, the PS2500 optocouplers boast high heat resistance and high moisture resistance. Table 1
lists the major features of the PS2500 series optocouplers.
