B2050CALRP Description

Short technical summary and product information.

The Littelfuse B2050CALRP is a Battrax series single positive SIDACtor overvoltage protection device optimized for Subscriber Line Interface Circuit (SLIC) applications. It uses mixed technology combining an SCR and gate diode to provide programmable breakdown voltage via an external VREF reference. The device begins conduction at |VREF| + 1.2 V and offers a range up to |VREF| + 10 V.

 

The part offers an off-state capacitance of 30 pF to 200 pF (measured at 1 MHz, 2 V bias), ensuring minimal loading on telecom lines. It features a maximum on-state voltage of 4 V at 2.2 A, with a maximum switching current of 100 mA and a minimum holding current of 100 mA. These parameters make it suitable for protecting sensitive SLIC components from transient overvoltages.

 

The B2050CALRP is offered in a surface mount DO-214AA (SMB) package with 3 leads (Compak format), designed for automated assembly. It meets RoHS3 compliance with Pb-free E3 finish. The part belongs to the Battrax family, which is recognized under UL file E133083.
