TLP250H(F)

Logic Output Optoisolators Overview

The TLP250H(F) is a high-performance, unidirectional photocoupler consisting of a GaAlAs infrared LED optically coupled to an integrated high-gain, high-speed photodiode array and output buffer. It features a push-pull output stage capable of delivering a peak output current of ±2.5 A. The device operates with a supply voltage range of 10 V to 30 V and supports a maximum continuous output current of 2.5 A. Key electrical parameters include a rise time of 50 ns, a fall time of 50 ns, and a propagation delay of 500 ns maximum. It provides an isolation voltage of 3750 Vrms and a common-mode transient immunity of ±40 kV/µs minimum.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix (TP1, F) against the manufacturer's official datasheet to confirm package type and reel/tube packaging specifications. Ensure the ordered part matches the required safety certifications, such as UL 1577 or VDE, by checking the ordering options provided in the official documentation. Confirm that the input forward current and supply voltage requirements align with the system design constraints before procurement.

Logic Output Optoisolators Selection Notes

Select this component when high-speed signal transmission and high peak current driving are required for power semiconductor gates. The TLP250H(F) is suitable for applications demanding superior common-mode noise rejection compared to standard logic output optocouplers. Consider the DIP-8 package constraints and thermal management requirements for the specified operating temperature range of -40°C to 125°C during circuit design.

Logic Output Optoisolators Part Context

The TLP250H series belongs to Toshiba's high-speed logic output optocoupler family, designed specifically for driving power devices like IGBTs and MOSFETs.
