PS2802-1-L-A

Overview

The PS2802-1-L-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and is housed in a compact SSOP-4 package with a 1.27 mm pin pitch. The device provides high isolation voltage of 2500 Vrms between input and output circuits. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum collector current of 50 mA, and a typical current transfer ratio (CTR) of 2000%. It operates within a temperature range of -55°C to +100°C and has a power dissipation rating of 60 mW.

Feature Summary

• High isolation voltage capability for safe signal transmission across potential differences
• Compact surface-mount SSOP-4 package design suitable for space-constrained applications
• High current transfer ratio ensuring efficient signal coupling with low input current

Applications

• Industrial control systems requiring galvanic isolation
• Motor drive circuits for feedback signal isolation
• Power supply monitoring and control loops

Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified suppliers. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure storage conditions adhere to moisture sensitivity level guidelines to maintain reliability. Check for any obsolescence notices or lifecycle changes directly from the manufacturer.

Selection Notes

Select this component when high CTR and robust isolation are required in a small footprint. Consider the 80 V collector-emitter voltage limit for load compatibility. Evaluate thermal management needs given the 60 mW power dissipation constraint in enclosed environments. Compare switching speeds against application timing requirements.

Part Context

This part belongs to the PS2802 series of optocouplers, designed for general-purpose isolation tasks. It shares the same package form factor as other variants in the family but differs in internal transistor configuration and performance characteristics. The series is widely used in industrial and consumer electronics for reliable signal transfer.

Replacement Considerations

Direct substitutes may include PS2801-1-L-A for single-channel NPN output applications, though CTR and speed characteristics differ. Verify pinout compatibility and electrical ratings before substitution. Consult Renesas documentation for qualified alternative parts within the same product line.
