TLP291-4 Datasheet, Description
Photocouplers GaAs Infrared LED & Photo Transistor
TLP291-4
TLP291-4
1. Applications
• Programmable Logic Controllers (PLCs)
• Switching Power Supplies
• Simplex/Multiplex Data Transmission
2. General
The Toshiba TLP291-4 consists of phototransistors optically coupled to gallium arsenide infrared emitting diodes.
The TLP291-4 Photocoupler is housed in the very small and thin SO16 package.
Since the TLP291-4 is guaranteed over a wide operating temperature range (Ta = -55 to 110), it is suitable for
high-density surface mount applications such as programmable controllers.
3. Features
(1) Collector-emitter voltage: 80 V (min)
(2) Current transfer ratio: 50% (min)
GB Rank: 100% (min)
(3) Isolation voltage: 2500 Vrms (min)
(4) Operating temperature: -55 to 110
(5) Safety standards
UL-approved UL1577 File No.E67349
cUL-approved CSA Component Acceptance Service No.5A File No.E67349

Un datasheet est un document fourni par le constructeur du composant, où figurent toutes les données techniques sur le produit: puissance dissipée, courant maximal, tension de seuil, tension de claquage, température de stockage, etc. Ils sont en général fournis gratuitement, et se présentent très régulièrement sous la forme d'un document pdf.
