V56ZT2P is a resettable fusing chip produced by Littelfuse. This device is a very compact variant of the popular PTC (positive temperature coefficient) family of resettable fuses. It is designed for a wide range of applications, including automotive, telecom, computers, audio, and other general-purpose applications requiring resettable protection from over-current. This device features an extended hold current of 2A at 70 degC, making it suitable for low current protection up to 2A. The V56ZT2P has an extended hold current of 2A at 55 degC, allowing its use in a wider temperature range than other resettable PTCs.
