Overview
The PS2801C-4-M-A is a four-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and operates within a temperature range of -55°C to +100°C. The device provides high isolation voltage of 2500 Vrms and utilizes a 16-pin SSOP package with a 1.27 mm pin pitch. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum forward current of 30 mA, and a typical forward voltage of 1.2 V. The unit weight is listed in specifications.
Feature Summary
- High isolation voltage rating for reliable signal transmission across isolated circuits
- Compact and thin small outline package design suitable for space-constrained applications
- Four independent channels integrated into a single component for multi-signal isolation
Applications
- Industrial control systems requiring multi-channel signal isolation
- Measurement equipment needing galvanic isolation between circuits
- Power supply units utilizing feedback loop isolation
Procurement Notes
Verify the specific suffix 'M-A' against official Renesas documentation to confirm package type and compliance status. Ensure the component meets RoHS requirements for your target market. Check current lifecycle status as availability may vary. Confirm that the 16-pin SSOP footprint matches your PCB design constraints before ordering.
Selection Notes
Select this component when multiple isolated channels are required in a compact form factor. The 2500 Vrms isolation rating suits general industrial applications. Consider the 30 mA forward current limit and 80 V collector-emitter voltage for circuit compatibility. Verify thermal management needs given the operating temperature range up to 100°C.
Part Context
This part belongs to the PS2801C series of high isolation voltage SSOP photocouplers. The series includes variants with different channel counts and package options. Renesas designs these devices using GaAs LEDs and NPN silicon phototransistors for robust performance. The family is intended for applications demanding reliable electrical isolation in small packages.
Replacement Considerations
Direct substitutes include PS2801C-4-V-A and PS2801C-4-F3-M-A from Renesas. These alternatives share similar isolation ratings and channel configurations. Verify pinout compatibility and specific electrical parameter differences before substitution.
