| SFH6156-3X007 | Optocoupler - Transistor, Photovoltaic Output | Vishay Semiconductor Opto Division | 贸泽采购 |
| Type | Output Device | Key Features | Typical Applications |
|---|---|---|---|
| Transistor Output | Bipolar Junction Transistor (BJT) | - Cost-effective - Moderate speed - Analog & digital isolation |
- Logic isolation - Power supply feedback - I/O interfacing |
| Photovoltaic Output | Photodiode array driving MOSFET gate | - No external power needed for output - High isolation voltage - Used to drive MOSFET/IGBT gates |
- Solid-state relays (SSR) - Gate driving in isolated circuits - Medical equipment, industrial controls |
Note: Transistor-output photocouplers use light to activate a BJT for signal transfer. Photovoltaic-output types generate voltage via integrated photodiodes to turn on external MOSFETs—ideal for high-side switching and safety-critical isolation.
