Toshiba shrinks optocoupler size by 17%

Toshiba Electronics has announced two miniature photocouplers that are designed to as ‘drop-in’ replacements for some of the company’s existing coupler parts while reducing board mounting profiles by over 17%. The TLP184 and TLP185 ‘mini-flat’ couplers can be used as direct replacements for Toshiba’s TLP180 and TLP181. These devices are used in applications ranging from programmable controllers and AC/DC input modules to telecommunications devices and office equipment. Pin- and functionally-compatible with their predecessors, the new devices have a maximum profile of just 2.3mm. They offer the same minimum isolation voltage (BVs) of 3750Vrms but have a higher insulation peak voltage (UIORM) of 707V. Both of the new photocouplers are designed to operate across an extended temperature range from -55ºC to 110ºC and have minimum collector-emitter voltages of 80V. The TLP184 ca...
