TLP250
The TLP250 is a single-channel optoisolator from Toshiba with an adaptable input on side 1 and a logic output. At 40kV/µs, it offers exceptional common-mode transient immunity, making it appropriate for a range of DC input applications.
Description
Feature
The TLP250 is a totem pole output logic type single-channel optoisolator. With its ability to manage a peak output current of ±2.5 A, it fits the bill for applications that require robust signal isolation. With a low supply current of 3 mA and a working voltage range of 10V to 30V, it can operate in the temperature range of -40°C to 125°C. With a maximum propagation delay time of 500 ns, this product ensures rapid signal transmission. Its high isolation voltage of 3750 Vrms (min) and good common-mode transient immunity at ±40 kV/µs (min) make it dependable for isolation-required applications.
Application
- The TLP250 is extensively utilized in various electronic systems, such as IGBT Gate Drivers, Industrial Inverters, and Air Conditioner Inverters. Its noteworthy use is in MOSFET Gate Drivers, where it is essential to the accurate and effective control of MOSFET devices. In this way, this model improves the functionality of MOSFET-driven systems and makes a substantial contribution to the best possible performance of electronic circuits.
Packaging
- There are many models in the TLP250 series, each with eight pins and a DIP8 package. The appearance may vary slightly depending on the specific model.
