| BAT54 THRU BAT54S Schottky Diodes SOT-23 .122 (3.1) .118 (3.0) .016 (0.4) 3 FEATURES These diodes feature very low turn-on Top View .056 (1.43) .052 (1.33) voltage and fast switching. These devices are protected by a PN 1 2 max. .004 (0.1) junction guard ring against excessive voltage, such as electrostatic discharges. .007 (0.175) .005 (0.125) .037(0.95) .037(0.95) .045 (1.15) .037 (0.95) .016 (0.4) .016 (0.4) .102 (2.6) .094 (2.4) MECHANICAL DATA Case: SOT-23 Plastic Package Weight: approx. 0.008 g Dimensions in inches and (millimeters) 3 3 Top View 1 2 1 2 BAT54 Marking: L4 3 BAT54A Marking: L42 3 Top View 1 2 1 2 BAT54C Marking: L43 BAT54S Marking: L44 MAXIMUM RATINGS AND ELECTRICAL CHARACTERISTICS FOR ONE DIODE Ratings at 25 C ambient temperature unless otherwise specified Symbol Repetitive Peak Reverse Voltage Forward Continuous Current at Tamb = 25 C Repetitive Peak Forward Current at Tamb = 25 C Surge Forward Current at tp < 1 s, Tamb = 25 C Junction Temperature Storage Temperature Range 1) Value 30 2001) 3001) 6001) 150 -65 to +150 Unit V mA mA mA C C VRRM IF IFRM IFSM Tj TS Device on fiberglass substrate, see layout. 4/98 BAT54 THRU BAT54S ELECTRICAL CHARACTERISTICS Ratings for one diode at 25 C ambient temperature unless otherwise specified Symbol Reverse Breakdown Voltage tested with 100 A Pulses Forward Voltage Pulse Test tp < 300 s, < 2% at IF = 0.1 mA at IF = 1 mA at IF = 10 mA at IF = 30 mA at IF = 100 mA Leakage Current Pulse Test tp < 300 s, < 2% at VR = 25 V Capacitance at VF = 1 V, f = 1 MHz Reverse Recovery Time from IF = 10 mA through IR = 10 mA to IR = 1 mA, RL = 100 Thermal Resistance Junction to Ambient Air 1) Min. 30 Typ. - Max. - Unit V V(BR)R VF VF VF VF VF IR - - - - - - - - - - - - 240 320 400 500 1000 2 mV mV mV mV mV A Ctot trr - - - - 10 5 pF ns RthJA - - 4301) K/W Device on fiberglass substrate, see layout .30 (7.5) .12 (3) .04 (1) .08 (2) .04 (1) .08 (2) .59 (15) .47 (12) .03 (0.8) 0.2 (5) .06 (1.5) .20 (5.1) Dimensions in inches (millimeters) Layout for RthJA test Thickness: Fiberglass 0.059 in (1.5 mm) Copper leads 0.012 in (0.3 mm) |
