7500Vpk isolation in a 6-SMD Gull Wing
The H11A5SR2M: Its 7500Vpk isolation rating suits applications requiring reinforced isolation between a DC input and a low-voltage output stage — think medical patient-interface barriers or industrial sensor isolation where the working voltage stays under 30V on the output side. The 30% minimum current transfer ratio at 10mA forward current means the output transistor saturates reliably with modest LED drive, while the 2µs typical turn-on and turn-off times keep switching losses low in 10-100 kHz signal paths.
onsemi lists the H11A5SR2M as obsolete. For sustainment programs that cannot requalify a replacement, the 6-SMD Gull Wing package and Tape & Reel packaging match the original production format, easing last-time-buy inventory management.
Parametric fit for the BOM line
The 30V maximum output voltage and 400mV Vce saturation at rated current define the load-switching envelope — the output transistor can drive logic-level inputs or low-power relays directly without a buffer stage. Operating temperature spans -40°C to 100°C, covering industrial and telecom ambient ranges. The 60 mA maximum DC forward current gives headroom for LED drive above the 10mA CTR test point.
