Product details

The H11A817B300W: Quantities are lot-specific, and we confirm availability and current pricing at quote time against an RFQ.

5300Vrms isolation — the fit decision

Rated for 5300Vrms isolation between input and output — this is a reinforced-insulation grade per IEC 60950-1, suitable for medical equipment, industrial PSUs, and motor-drive feedback where galvanic separation protects the low-voltage control side from the high-voltage power rail. The single-channel transistor output delivers a 130% to 260% current transfer ratio at a 5mA forward current — the CTR band is tight enough that the opto's gain does not vary wildly across the reel, so the pull-up resistor value stays predictable across the BOM.

4-DIP through-hole — board integration

Rated for -55°C to +100°C operating temperature, covering industrial and extended-temperature environments. The 70V maximum output voltage and 50mA output current handle logic-level and low-power relay interfaces.

Frequently asked questions

How do I get pricing and availability for H11A817B300W?

Submit an RFQ against your BOM quantity. We source through independent distribution and confirm current pricing and lot availability at quote time.

What is the closest pin-compatible alternative to H11A817B300W?

No official pin-compatible successor is recorded from onsemi. A parametric replacement within the same 4-DIP footprint and 5300Vrms isolation class would need a CTR band that matches the 130-260% window at 5mA — a board-level substitution requires verifying the CTR and Vce(sat) against the original design margin.
