Overview
The PS8802-1-F3-A is a high-speed, single-channel optically coupled isolator manufactured by CEL. It integrates a GaAlAs LED on the input side with a PIN photodiode and high-speed amplifier transistor on the output side within a single chip. Designed for applications requiring high common-mode transient immunity (CMR), this component operates at data speeds up to 1 Mbps. The device features an analog output type and is housed in an 8-pin SSOP package. Key electrical specifications include a minimum common-mode transient immunity of 15 kV/µs, an isolation voltage of 2500 Vrms, and a propagation delay of 0.8 ns (tPHL) and 1.2 ns (tPLH).
Feature Summary
- High common-mode transient immunity designed for noisy environments.
- Single-channel architecture integrating LED and high-speed amplifier on one chip.
- Analog output configuration suitable for precise signal transmission.
- Compliant with UL, VDE, and CSA safety standards.
Applications
- High-speed logic interface circuits
- Industrial automation systems
- Measurement equipment
Procurement Notes
Verify the specific suffix (e.g., -F3-A) against the manufacturer's current datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the required safety certifications (UL, VDE, CSA) are explicitly listed for the ordered variant. Ensure the operating temperature range meets system requirements before finalizing procurement.
Selection Notes
Select this component when a single channel with analog output and high CMR is required. Compare propagation delays and CTR values against system timing constraints. Ensure the 8-pin SSOP package fits the PCB layout. Verify that the 1 Mbps speed is sufficient for the application, as higher-speed digital options may be available in other series.
Part Context
The PS8802 series belongs to CEL's family of high-speed photocouplers. The PS8802-1 variant specifically denotes a single-channel configuration, distinguishing it from dual-channel models like the PS8802-2. This series is engineered to provide robust isolation in electrically noisy industrial environments while maintaining signal integrity through high-speed amplification.
Replacement Considerations
Check for direct pin-compatible replacements within the PS8802 series, such as the PS8802-1-V-F3 or PS8802-1-F3, ensuring identical electrical characteristics and package dimensions. Verify that any substitute maintains the same safety approvals and CMR ratings.
FAQ
What is the typical propagation delay for the PS8802-1-F3-A?
The maximum propagation delay is 0.8 ns for low-to-high transition (tPHL) and 1.2 ns for high-to-low transition (tPLH).
Does the PS8802-1-F3-A support digital or analog output?
It features an analog output type, utilizing a PIN photodiode and high-speed amplifier transistor.
