The H11A5TM comes in a 6-DIP (0.400", 10.16 mm) through-hole package, supplier device package 6-DIP. The 0.100-inch pin pitch and standard DIP footprint suit socketed or soldered mounting on a PCB without requiring a fine-pitch assembly process.
Isolation and switching performance
Isolation voltage is 7500Vpk — this is a high-creepage design for applications requiring reinforced isolation between the input and output circuits, such as in motor drives or power supplies where transient overvoltages are common. Minimum current transfer ratio (CTR) is 30% at 10 mA forward current, ensuring the output transistor drives a logic input or relay coil with adequate margin. Typical turn-on and turn-off times are 2 µs each, which limits the usable switching frequency to below about 50 kHz for clean edge detection.
onsemi lists the H11A5TM as Obsolete. Sourcing is through independent distribution channels; quantities are lot-specific and confirmed at RFQ.
