Description

PS2502-1-A is Sharp’s 1-channel optocoupler (photocoupler) in a DIP-4 package. It provides galvanic isolation between input and output by optically coupling an infrared LED to a phototransistor. The input side is driven by a LED current; the output side switches a load via the phototransistor, enabling signal transfer across voltage/noise barriers. Common uses include isolating microcontrollers from high-voltage circuits, driving relays/triacs, and providing noise-free signaling in power supplies or PLCs. Key specs to check in the datasheet are the isolation voltage (VISO), current transfer ratio (CTR) at a given IF, input forward current, and output leakage/switching speed. Typical pinout (DIP-4): Pin 1 LED anode, Pin 2 LED cathode, Pin 3 transistor emitter, Pin 4 transistor collector (verify for your exact part). Variants differ in CTR, speed, and package details. For exact electrical characteristics, consult the PS2502-1-A datasheet.

Package

8-pin DIP (DIP-8) through-hole package.

Pinout

Pin count: 4 pins (DIP-4).
Function: Optocoupler (photocoupler) with input LED and an NPN phototransistor output. Typical pinout: 1 = Anode, 2 = Cathode (LED input); 3 = Emitter, 4 = Collector (output transistor).

Manufacturer

Manufacturer: Sharp Corporation (Sharp Microelectronics).
What kind of company: A Japanese multinational electronics company that designs and manufactures a wide range of electronic components and consumer electronics, sold worldwide (e.g., optocouplers, sensors, displays, etc.).

Application

PS2502-1-A is a Sharp optocoupler with galvanic isolation. Typical applications:
- Isolated interfaces between low-voltage logic (microcontrollers) and high-voltage/noisy power sections
- Isolation in switch-mode power supplies and feedback circuits
- Relay/SSR driving and motor-control interfaces
- Industrial, medical, and telecom equipment requiring electrical isolation and noise immunity

Equivalent

Assuming PS2502-1-A is a Sharp optocoupler (phototransistor output, DIP-4), common equivalents include: PC817, LTV-817 (or LTV-817A), 4N25, HCPL-817, EL817. Note: verify CTR, input LED current, and pinout to ensure an exact replacement.
