TLP174GA TOSHIBA Photocoupler Photorelay TLP174GA ModemFax Cards, Modems in PC Unit: mm Telecommunications PBX Measurement Equipment The Toshiba TLP174GA consists of an aluminum gallium arsenide infrared emitting diode optically coupled to a photo-MOSFET in a SOP, which is suitable for surface mount assembly. The TLP174GA is suitable for the modem applications which require space savings. 4-pin SOP (2.54SOP4): Height = 2.1 mm, Pitch = 2.54 mm 1-Form-A Peak Off-state voltage: 400 V (min) Trigger LED current: 3 mA (max) On-state current: 120 mA (max) Limit current: 150 mA~300 mA (t = 5 ms) On-state resistance: 35 (max) Isolation voltage: 1500 Vrms (min) JEDEC JEITA Pin Configuration (top view) TOSHIBA 11-5H1 Weight: 0.1 g (typ.) 1 4 1: Anode 2: Cathode 3: Drain 4: Drain 2 3 Start of commercial production 2002/01 1 2014-09-22 TLP174GA Absolute Maximum Ratings (Ta = 25C) Characteristics Symbol Rating Unit Forward current I 50 mA F Forward current derating (Ta 25C) I /C 0.5 mA/C F Peak forward current LED I 1 A FP (100 s pulse, 100 pps) Reverse voltage V 5 V R Junction temperature T 125 C j Off-state output terminal voltage V 400 V OFF On-state current I 120 mA ON Detector On-state current derating (Ta25C) I /C 1.2 mA/C ON Junction temperature T 125 C j Storage temperature range T 55 to 125 C stg Operating temperature range T 40 to 85 C opr Lead soldering temperature (10 s) T 260 C sol Isolation voltage (AC, 1 minute, R.H. 60%) BV 1500 Vrms S (Note 1) 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: Device considered a two-terminal device: LED side pins shorted together, and detector side pins shorted together.
