2920L075DR Description

Short technical summary and product information.

The Littelfuse 2920L075DR is a PolySwitch resettable PTC overcurrent protection device designed for medium voltage applications up to 30V. It features a hold current of 750 mA and a trip current of 1.5 A at 20°C still air, with a maximum fault current rating of 40 A. The device trips within 300 ms at 8 A, providing fast response to overcurrent conditions.

 

This surface mount component is housed in a 2920 (7351 Metric) concave package measuring 7.35 mm x 5.12 mm with a maximum thickness of 1.25 mm. It offers low initial resistance (0.35 Ω minimum) and a maximum post-trip resistance of 1 Ω, ensuring minimal power loss during normal operation. Typical power dissipation in the tripped state is 1.5 W.

 

The 2920L075DR operates over a temperature range of -40°C to 85°C, making it suitable for a wide variety of environments. Its resettable nature eliminates the need for fuse replacement after a fault, reducing maintenance and downtime in electronic circuits.
