Overview
The PC353TJ0000F is a single-channel optoisolator manufactured by Sharp Microelectronics, featuring a transistor output with an accessible base terminal. It provides a high isolation voltage of 3750Vrms and supports a maximum collector-emitter voltage of 80V. The device operates within a temperature range of -30°C to 100°C and utilizes a 5-SMD surface-mount package. Key electrical parameters include a typical forward voltage of 1.2V, a maximum DC forward current of 50mA, and a maximum collector current of 50mA. The saturation voltage is limited to 200mV, with typical rise and fall times of 4µs and 3µs respectively.
Feature Summary
- Integrates a phototransistor output with a dedicated base pin for external control or gain adjustment
- Provides robust galvanic isolation rated at 3750Vrms between input and output circuits
- Designed for surface-mount assembly in compact 5-lead SMD configurations
Applications
- Industrial control systems requiring signal isolation
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify component authenticity through authorized distributors as the part status is listed as obsolete. Confirm RoHS compliance status, as standard versions may not meet current environmental regulations. Ensure the specific suffix matches required packaging and regulatory certifications before finalizing procurement orders.
Selection Notes
Select this component when a transistor output with base access is required for precise current control or linear operation. The 3750Vrms isolation rating suits applications demanding high voltage separation. Consider the 5-SMD package constraints and thermal management requirements for the specified operating temperature range during PCB layout design.
Part Context
This component belongs to Sharp Microelectronics' PC353 series of optocouplers. The series typically offers various output types and packaging options. The PC353T variant specifically denotes the transistor output with base configuration, distinguishing it from other variants like the PC353NJ or PC354N which feature different output structures or pin counts.
Replacement Considerations
PC353TJ0000F is the full specification part number including packaging and compliance suffixes. Direct equivalents should match the 5-SMD package, 3750Vrms isolation, and transistor-with-base output type.
