TLP172A TOSHIBA Photocoupler Photorelay TLP172A Telecommunications Unit: mm Control Equipment Data Acquisition System Security Equipment Measurement Equipment The Toshiba TLP172A consists of a gallium arsenide infrared emitting diode optically coupled to a photo-MOSFET in a 4-pin SOP package. This photorelay has higher output current rating than phototransistor-type photocoupler hence, it is suitable for use as On/Off control for high current. 4-pin SOP (2.54SOP4): Height = 2.1 mm, pitch = 2.54 mm Normally open (1-form-A) device Peak off-state voltage: 60 V (min) Trigger LED current: 3 mA (max) On-state current: 400 mA (max) On-state resistance: 2 (max) JEDEC Isolation voltage: 1500 Vrms (min) UL recognized: UL1557, File No.E67349 JEITA TOSHIBA 11-5H1 Pin Configuration (top view) Weight: 0.1 g (typ.) 1 4 1: Anode 2: Cathode 3: Drain 4: Drain 2 3 1 2002-04-25 TLP172A Maximum Rating (Ta 25C) Characteristics Symbol Rating Unit Forward current I 50 mA F Forward current derating I /C 0.5 mA/C F (Ta 25C) LED Reverse voltage V 5 V R Junction temperature T 125 C j Off-state output terminal V 60 V OFF voltage On-state current I 400 mA ON Detector Forward current derating I /C 4.0 mA/C ON (Ta 25C) Junction temperature T 125 C j Storage temperature T 55 to 125 C stg Operating temperature T 40 to 85 C opr Lead soldering temperature (10 s) T 260 C sol Isolation voltage (AC, 1 min, R.H. 60%) BV 1500 Vrms S (Note 1) Note 1: LED pins are shorted together.
