Description

OPB625 is an optocoupler (optoisolator) with an infrared LED input and a phototransistor output. It provides galvanic isolation between a low-voltage control side and a high-voltage/noisy side, letting a logic signal control a circuit without a shared ground. When the LED is driven, light activates the transistor, allowing current to flow on the output side.
Key points:
- Package: typically 4-pin DIP (variants exist). Pinout usually: pin 1 anode, pin 2 cathode, pin 3 emitter, pin 4 collector (verify in the datasheet).
- Isolation: several kilovolts RMS between input and output.
- CTR: current transfer ratio depends on LED current and temperature; specified in the datasheet.
- Speed: suitable for low- to moderate-speed signaling (tens to thousands of Hz, depending on variant).
Common uses: microcontroller or PLC signal isolation, SMPS control, sensing where galvanic isolation is needed.
For exact electrical specs (IF, CTR, VCE(sat), tPHL/tPLH) and packaging variants, consult the OPB625 datasheet.

Features

OPB625 is a phototransistor optocoupler (optoisolator). Key features (typical; variant-dependent):
- Isolation: ~5 kV RMS between input LED and output transistor
- CTR: roughly 50–300% at IF = 20 mA (up to 600% max, depending on variant and temperature)
- Input: Infrared LED, IF ≈ 20 mA, Vf ≈ 1.2 V
- Output: NPN phototransistor (max IC ~50 mA)
- Speed: standard (not high‑speed); t_r/t_f in the μs range
- Package: DIP‑4 or similar SMD variants
- Operating temp: typically −40 to +85 °C (industrial); wider on some versions
- Applications: galvanic isolation for logic/data signals, microcontroller interfacing, safety-critical isolation
Note: exact numbers (CTR, VCEO, speed) vary by variant (e.g., OPB625A/B). Check the specific datasheet for precise specs.

Package

OPB625 is a single-channel optocoupler packaged in a standard 4-pin DIP (through-hole) package.

Pinout

OPB625 is a 4‑pin DIP optocoupler (optical isolator). It has an input LED and a phototransistor output, providing isolation between input and output.
Pinout (typical):
- Pin 1: Anode
- Pin 2: Cathode
- Pin 3: Emitter
- Pin 4: Collector
The LED (pins 1–2) drives the phototransistor (pins 3–4) to transfer a signal across isolation.

Manufacturer

OPB625 is manufactured by OPTEK Technology. OPTEK is an optoelectronics company that designs and manufactures optocouplers, phototransistors, LEDs, and other optical/electrical components.

Application

OPB625 is a phototransistor-output optocoupler. Applications include galvanic isolation between low-voltage logic and high-voltage/noisy circuits; interfacing microcontrollers with power electronics; feedback and sensing in switching power supplies; driving relays/triacs and motor drivers; signal isolation in automation/PLC I/O and data communication interfaces; instrumentation and safety-critical equipment requiring isolation.
