ISOCOM CH101

The CH100 series is a single channel radiation hard optically coupled isolator. It is composed of an infrared emitting diode and a silicon phototransistor.

The CH100 has been designed and manufactured to meet the requirements of very low temperatures experienced in harsh environments encountered by space applications. These devices can be wire bonded within a hybrid application or mounted directly onto a PCB board offering the customer flexibility in their design. Package styles for this device include a 4-pin surface mount package, with solder dip option available.

Absolute maximum ratings, recommended operating conditions, electrical specifications and performance characteristics are identical for all units. Any exceptions, due to packaging variations and limitations, are as noted.

Key features of the CH101 include:

• Total Ionizing Dose tested to 150 Krad(Si)
• Displacement Damage to 1 MEV x 10¹²
• Low Temperature Operation up to -150°C
• 4-pin Surface Mount Package
• Flexibility in Design for mounting styles
• High Current Transfer Ratio
• High Isolation Voltage up to 1,000Vdc

Typical applications for the CH101 include:

• Space Equipment and Systems
• Military and High Reliability Systems
• Medical Instruments
• Suitable for Hybrid Packaging
• MOS/CMOS Applications
• Data Transmission
• Power Supply
• Logic Interfacing
