Central CTLSH05-4M521 TM Semiconductor Corp. SURFACE MOUNT LOW VF SILICON SCHOTTKY DIODE Top View Bottom View DESCRIPTION: The CENTRAL SEMICONDUCTOR CTLSH05-4M521 Low VF Schottky Diode is a high quality Schottky Diode designed for applications where small size and operational effciency are the prime requirements. With a maximum power dissipation of 0.9W, and a very small package footprint (comparable to the SOT-563), this leadless package design is capable of dissipating over 3 times the power of similar devices in comparable sized surface mount packages. FEATURES: TLM521 CASE • Very Small Package Size • Current (IF=0.5A) • Low Forward Voltage Drop (VF=0.47V MAX @ 0.5A) MARKING CODE: CA • High Thermal Efficiency • Small TLM 2x1mm case APPLICATIONS: • DC/DC Converters • Voltage Clamping • Protection Circuits MAXIMUM RATINGS: (TA=25°C) • Battery Powered Portable Equipment SYMBOL Peak Repetitive Reverse Voltage UNITS VRRM 40 V IF 500 mA Peak Repetitive Forward Current, tp ≤ 1ms IFRM 3.5 A Forward Surge Current, tp = 8ms IFSM 10 A PD 0.9 W* TJ, Tstg -65 to +150 °C ΘJA 139 °C/W* Continuous Forward Current Power Dissipation Operating and Storage Junction Temperature Thermal Resistance ELECTRICAL CHARACTERISTICS: SYMBOL TEST CONDITIONS IR IR BVR VR= 10V VR= 30V IR= 500μA VF VF IF= 100μA IF= 1.0mA IF= 10mA VF VF VF CT (TA=25°C unless otherwise noted) IF= 100mA IF= 500mA VR=1.0V, f=1.0MHz *FR-4 Epoxy PCB with copper mounting pad area of 33mm2 MIN MAX UNITS 20 μA 100 μA V 0.13 V 0.21 V 40 0.27 V 0.35 V 0.47 V 50 pF R1 (27-April 2006) Central TM CTLSH05-4M521 SURFACE MOUNT LOW VF SILICON SCHOTTKY DIODE Semiconductor Corp.
