HMHAA280

HALF PITCH MINI-FLAT PACKAGE 4-PIN OPTOCOUPLERS HMHAA280 DESCRIPTION The HMHA series consists of a gallium arsenide infrared emitting diode driving a silicon phototransistor in a compact 4-pin mini-flat package. The lead pitch is 1.27 mm. The HMHAA series consists of two gallium arsenide infrared emitting diodes, connected in inverse parallel, driving a single silicon phototransistor in a compact 4-pin mini-flat package. HMHA2801 HMHA281 FEATURES Compact 4-pin package (2.4 mm maximum standoff height) Half pitch leads for optimum board space savings Current Transfer Ratio in selected groups HMHAA280: 50-600% HMHA2801: 80-600% HMHA281: 50-600% Available in tape and reel quantities of 500 and 2500 Applicable to Infrared Ray reflow (230°C Max, 30 seconds) BSI (File #8611/8612), CSA (File #1201524), UL (File #E90700) and VDE (File #136480) certified PACKAGE DIMENSIONS PIN 1 0.050 (1.27) 0.020 (0.51) 0.012 (0.30) 0.287 (7.29) 0.248 (6.30) 0.173 (4.40) TYP 0.106 (2.69) 0.091 (2.31) APPLICATIONS HMHAA series AC line monitor Unknown polarity DC sensor Telephone line receiver HMHA series Digital logic inputs Microprocessor inputs Power supply monitor Twisted pair line receiver Telephone line receiver 1 4 COLLECTOR 2 3 EMITTER 0.094 (2.39) 0.079 (2.01) Equivalent Circuit (HMHAA280) ANODE 1 4 COLLECTOR 0.035 (0.89) 0.012 (0.30) 0.008 (0.20) 0.000 (0.0) 0.030 (0.75) 0.022 (0.55) CATHODE 2 3 EMITTER Equivalent Circuit (HMHA281, HMHA2801) NOTE All di...
