TLP291(SE
TLP291(SE
1. Applications
• Switching Power Supplies
• Programmable Logic Controllers (PLCs)
• I/O Interface Boards
2. General
TLP291(SE consists of photo transistor optically coupled to an infrared emitting diode.
TLP291(SE is housed in the SO4 package, very small and thin coupler.
Since TLP291(SE is guaranteed wide operating temperature (Ta = -55 to
110 ) and high isolation voltage (3750 Vrms), it's suitable for high-density
surface mounting applications such as small switching power supplies and
programmable controllers.
3. Features
(1) Collector-emitter voltage: 80 V (min)
(2) Current transfer ratio: 50 % (min)
GB Rank: 100 % (min)
(3) Isolation voltage: 3750 Vrms (min)
(4) Operating temperature: -55 to 110
(5) Safety standards
UL-recognized: UL 1577, File No.E67349
cUL-recognized: CSA Component Acceptance Service No.5A File No.E67349
VDE-approved: EN 60747-5-5, EN 62368-1 (Note 1)
CQC-approved: GB4943.1, GB8898 Japan and Thailand Factory
Note 1: When a VDE approved type is needed, please designate the Option (V4).

Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even
if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum
ratings.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
("Handling Precautions"/"Derating Concept and Methods") and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
Note 1: Pulse width (PW) 0.1 ms, f = 100 Hz
Note 2: This device is considered as a two-terminal device: Pins 1 and 2 are shorted together, and pins 3 and 4 are
shorted together.
