Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISP817BLSMT&R is determined by strict equivalence across the following critical parameters:

• Voltage isolation rating: 5300Vrms
• Number of channels: 1
• Output type: Transistor
• Current transfer ratio range: 200% to 600% @ 5mA
• Maximum output voltage: 80V
• Maximum output current per channel: 50mA
• Maximum Vce saturation: 200mV
• Rise and fall time specifications: 4µs and 3µs
• Operating temperature range: -55°C to 110°C
• Package type: 4-SMD (0.300", 7.62mm)
• Mounting type: Surface Mount

Parts meeting all these parameters are considered parametric equivalents and direct substitutes for the ISP817BLSMT&R.
