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

• Isolation materials according to UL94-VO

• Pollution degree 2 (DIN/VDE 0110/resp. IEC

60664)

IEC 60112 comparative tracking index: CTI ≥ 175

• Rated impulse voltage (transient overvoltage)

VIOTM = 8 kV peak

• Isolation test voltage (partial discharge test voltage)

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

• Line receiver

• Computer peripheral interface

• Microprocessor system interface

• Circuits for safe protective separation against electrical

shock according to safety class II (reinforced isolation):

- for appl. class I - IV at mains voltage ≤ 300 V

- for appl. class I - III at mains voltage ≤ 600 V

according to DIN EN 60747-5-5.
