TOSHIBA TLP250 Photocoupler | GaAlAs Ired & Photo-IC | DIP-8 / SMD Gate Driver IC
Rs.170.00
Overview of the TOSHIBA TLP250 Photocoupler
The TOSHIBA TLP250 is a highly reliable photocoupler consisting of a GaAlAs light-emitting diode and an integrated photodetector. Packaged in a standard 8-lead DIP (with SMD options available), it is explicitly designed for high-performance gate driving circuits in IGBTs and power MOSFETs. Its rugged construction ensures superior isolation and fast switching times, making it an essential component for industrial inverters, motor controls, and power supplies.
Key Features
- High Isolation Voltage: Minimum 2500 Vrms isolation ensures safe electrical separation between control and power stages.
- Robust Output Current: Delivers a peak output current of ±1.5A (max), enabling rapid charging and discharging of gate capacitances.
- Fast Switching Speed: Maximum propagation delay (tpLH / tpHL) of just 0.5 μs for high-frequency applications.
- Wide Supply Voltage Range: Operates efficiently within a VCC range of 10V to 35V.
- Low Input Current: Requires a maximum input threshold current of only 5mA.
