Product details

5000Vrms reinforced isolation in a 6-SOIC body

The Renesas PS8302L-V-AX is a single-channel NEPOC phototransistor optocoupler in a 6-SOIC surface-mount package with a 6-SDIP supplier package designation. It provides 5000Vrms galvanic isolation between a DC input LED and a phototransistor output with base access, rated for industrial and high-reliability applications that demand reinforced isolation in a compact footprint. The output transistor is rated for 35V maximum and 8mA per channel, with the base terminal brought out — useful for adding a speed-up capacitor or base-emitter resistor to tailor switching behaviour.

CTR floor and LED drive budget

The minimum current transfer ratio is 15% at 16mA forward current. This is the number that sets the LED drive current in the BOM: to guarantee the output transistor saturates at a given load, you size the series resistor so the LED sees at least 16mA across the input voltage range, accounting for the 1.6V typical forward drop and the 25mA absolute maximum DC forward current. A 15% CTR floor is on the lower side for a phototransistor coupler — expect to need roughly 6.7mA of LED current per milliamp of output load current at the minimum. Designs with tight input-side power budgets should verify headroom at the cold end of the temperature range, where CTR typically degrades further.

Frequently asked questions

What is the current transfer ratio (CTR) of PS8302L-V-AX?

The minimum CTR is 15% at 16mA forward current. This is the guaranteed floor at room temperature; actual CTR at higher forward currents or elevated temperature will be higher, but the 15% minimum is the number to use for worst-case LED drive budgeting.

Is PS8302L-V-AX RoHS compliant?

Yes, it is ROHS3 compliant per the lifecycle record.

What PS8302L-V-AX equivalents are available?

The NEPOC family includes the PS8302L2-AX and PS8302L2-V-AX, which share the same 5000Vrms isolation, 8mA output, and DC input type. The key difference is the V-AX suffix variants carry the 6-SDIP supplier package designation versus the base -AX. Verify footprint compatibility before substituting across the family.

Can PS8302L-V-AX be used for isolated communication?

Yes, the phototransistor output with base access makes it suitable for isolated digital signalling up to moderate speeds — think status feedback, fault detection, and low-frequency data isolation. For high-speed serial buses (SPI, I2C, CAN), a digital isolator or optocoupler with a logic-level output would be a better fit.
