Its headline rating is 5000Vrms isolation between input and output, which covers reinforced-insulation requirements for motor-drive feedback, PLC digital inputs, and medical-grade power supplies where a single fault must not create a shock hazard. The transistor output delivers up to 8mA per channel with a 35V collector-emitter ceiling, so it can directly drive a logic gate input or a small relay coil without a buffer transistor. ## 220ns turn-on, 350ns turn-off — timing budget for isolated feedback Switching times of 220ns turn-on and 350ns turn-off typ at 16mA forward current place this part in the fast side of standard transistor-output optos. That speed lets it pass a 1 MHz PWM signal with acceptable edge degradation, which matters when the part is used in isolated gate-drive feedback for IGBT/MOSFET switching stages or in isolated ADC sampling triggers. The 1.7V typical forward voltage is on the low side for a 5V logic rail, so the LED can be driven directly from a 3.3V or 5V GPIO through a current-limiting resistor sized for the 16mA test point. ## Temperature range and package — where it goes Rated from -55°C to 100°C operating, the PS8502-AX is comfortable in outdoor telecom cabinets, factory-floor enclosures, and engine-bay electronics where commercial-grade parts would drift or latch. The 8-DIP through-hole package (0.300\" body width) is a legacy-friendly footprint — easy to hand-assemble, rework, or socket in a prototype — and the 7.62mm pin pitch matches standard perfboard and DIP sockets. Through-hole also helps with creepage distance on the PCB: the 8-DIP body gives natural spacing between primary and secondary sides when the part bridges a safety isolation barrier.","metaTitle":"PS8502-AX Renesas NEPOC Optoisolator, 5000Vrms, 8-DIP","metaDescription":"Renesas PS8502-AX NEPOC optoisolator: single-channel transistor output, 5000Vrms isolation, 220ns/350ns switching, -55°C to 100°C.","metaKeywords":null},"attributes":{"series":"NEPOC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Series":"NEPOC","Package":"Tube","Input Type":"DC","Output Type":"Transistor","Mounting Type":"Through Hole","Package / Case":"8-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Number of Channels":"1","Voltage - Isolation":"5000Vrms","Operating Temperature":"-55°C ~ 100°C","Voltage - Output (Max)":"35V","Supplier Device Package":"8-DIP","Current - Output / Channel":"8mA","Current Transfer Ratio (Min)":"15% @ 16mA","Voltage - Forward (Vf) (Typ)":"1.7V","Turn On / Turn Off Time (Typ)":"220ns, 350ns","Current - DC Forward (If) (Max)":"25 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.27","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.27000","currency":"USD"},{"qty":10,"price":"$2.31200","currency":"USD"},{"qty":100,"price":"$1.89350","currency":"USD"},{"qty":500,"price":"$1.59630","currency":"USD"},{"qty":1000,"price":"$1.46420","currency":"USD"},{"qty":2000,"price":"$1.40365","currency":"USD"},{"qty":5000,"price":"$1.37612","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/66ae71419c84b70fa437a42ac21aad29.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional second-source for the PS8502-AX?","answer":"The Renesas PS2801C-4-V-A is a multi-channel (4-channel) surface-mount transistor-output optoisolator with 2500Vrms isolation.
