CTLSH1-50M832DS surface mount dual, high current low v f silicon schottky rectifiers description: the central semiconductor ctlsh1- 50m832ds dual, isolated, low v f silicon schottky rectifiers are designed for applications where small size and operational efficiency are the prime requirements. with a maximum power dissipation of 1.65w, and a very small package footprint (approximately equal to the sot-23), this leadless package design is capable of dissipating up to 4 times the power of similar devices in comparable sized surface mount packages. marking code: cfx features: ? high current (i f =1.0a) ? low forward voltage drop (v f =0.55v max @ 1.0a) ? high thermal efficiency ? small tlm 3x2mm case applications: ? dc - dc converters ? reverse battery protection ? battery powered portable equipment maximum ratings: (t a =25c) symbol units peak repetitive reverse voltage v rrm 50 v continuous forward current i f 1.0 a peak repetitive forward current, tp<1.0ms i frm 3.5 a peak forward surge current, tp=8.0ms i fsm 10 a power dissipation (note 1) p d 1.65 w operating and storage junction temperature t j , t stg -65 to +150 c thermal resistance (note 1) ja 75.8 c/w electrical characteristics per diode: (t a =25c unless otherwise noted) symbol test conditions min typ max units i r v r =5.0v 10 a i r v r =8.0v 20 a i r v r =15v 50 a i r v r =50v 0.5 ma i r v r =50v, t a =100c 50 ma bv r i r =100a 50 v v f i f =10ma 0.29 v v f i f =100ma 0.36 v v f i f =500ma 0.45 v v f i f =1.0a 0.55 v c j v r =4.0v, f=1.0mhz 50 pf notes: (1) fr-4 epoxy pc board with copper mounting pad area of 54mm 2 tlm832ds case r1 (23-september 2011) www.centralsemi.com
