TLP3145
1. Applications
• ATE (Automatic Test Equipment)
• Measuring Instruments
• Factory Automation (FA)
• I/O Interface Boards
• Mechanical relay replacements
2. General
The TLP3145 photorelay consists of a photo MOSFET optically coupled to an infrared LED. It is housed in a 4-
pin package with 2.54-mm lead pitch and 2.1-mm height. The TLP3145 is a bi-directional switch, which can
replace mechanical relays in many applications. And its high on-state maximum rating current even with medium
voltage of 200 V and low on-state resistance is suitable to control a power line.
3. Features
(1) Package: SOP (2.54SOP4) (Height 2.1 mm, pitch 2.54 mm)
(2) Normally opened (1-Form-A)
(3) OFF-state output terminal voltage: VOFF = 200 V
(4) Trigger LED current: 3 mA (max)
(5) ON-state current: 0.4 A (max)
(6) ON-state resistance: 2.0 (max)
(7) Off-state capacitance: 100 pF (typ.)
(8) Off-state current: 1 µA (max)@VOFF = 200V
(9) Isolation voltage: 1500 Vrms (min)
(10) Safety standards
UL-recognized: UL 1577, File No.E67349
cUL-recognized: CSA Component Acceptance Service No.5A File No.E67349
4. Packaging and Pin Assignment
11-5H1S

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: This device is considered as a two-terminal device: Pins 1 and 2 are shorted together, and pins 3 and 4 are
shorted together.
