DESCRIPTION
The TCED2100/TCED4100 consists of a phototransistor
optically coupled to a gallium arsenide infrared-emitting
diode in a 8-pin (dual) or 16-pin (quad) plastic dual inline
package.
The elements are mounted on one leadframe providing a
fixed distance between input and output for highest safety
requirements.

VDE STANDARDS
These couplers perform safety functions according to the
following equipment standards:
• DIN EN 60747-5-5
Optocoupler for electrical safety requirements
• IEC 60950/EN 60950
Office machines (applied for reinforced isolation for mains
voltage ≤ 400 VRMS)
• VDE 0804
Telecommunication apparatus and data processing
• IEC 60065
Safety for mains-operated electronic and related
household apparatus

FEATURES

Vpd = 1.6 kV peak
• Rated isolation voltage (RMS includes DC)
VIOWM = 600 VRMS
• Rated recurring peak voltage (repetitive)
VIORM = 848 V peak
• Thickness though insulation ≥ 0.75 mm
• Lead (Pb)-free component
• Component in accordance to RoHS 2002/95/EC and
WEEE 2002/96/EC

APPLICATIONS
• Switch-mode power supplies
