| SPN8878 N-Channel Enhancement Mode MOSFET DESCRIPTION The SPN8878 is the N-Channel logic enhancement mode power field effect transistors are produced using high cell density , DMOS trench technology. The SPN8878 has been designed specifically to improve the overall efficiency of DC/DC converters using either synchronous or conventional switching PWM controllers. It has been optimized for low gate charge, low RDS(ON) and fast switching speed. FEATURES 30V/20A,RDS(ON)= 12m@VGS=10V 30V/15A,RDS(ON)= 17m@VGS=4.5V Super high density cell design for extremely low RDS (ON) Exceptional on-resistance and maximum DC current capability TO-252 package design APPLICATIONS Power Management in Note book Powered System DC/DC Converter Load Switch PIN CONFIGURATION TO-252 PART MARKING 2009/04/20 Ver.1 Page 1 SPN8878 N-Channel Enhancement Mode MOSFET PIN DESCRIPTION Pin 1 2 3 Symbol G S D Description Gate Source Drain ORDERING INFORMATION Part Number Package Part Marking SPN8878T252RGB TO-252 SPN8878T252RG : Tape Reel ; Pb - Free ; Halogen - Free SPN8878 ABSOULTE MAXIMUM RATINGS (TA=25 Unless otherwise noted) Parameter Drain-Source Voltage Gate -Source Voltage Continuous Drain Current Pulsed Drain Current Continuous Drain Current TO-252-2L Power Dissipation Operating Junction Temperature Storage Temperature Range Thermal Resistance-Junction to Ambient TA=25 TO-251 TA=25 TA=100 Symbol VDSS VGSS ID IDM IS PD TJ TSTG RJA Typical 30 20 18 13 40 5 40 55 150 -55/150 100 Unit V V A A A W /W 2009/04/20 Ver.1 Page 2 SPN8878 N-Channel Enhancement Mode MOSFET ELECTRICAL CHARACTERISTICS (TA=25 Unless otherwise noted) Parameter Static Drain-Source Breakdown Voltage Gate Threshold Voltage Gate Leakage Current Zero Gate Voltage Drain Current On-State Drain Current Drain-Source On-Resistance Forward Transconductance Diode Forward Voltage Dynamic Total Gate Charge Gate-Source Charge Gate-Drain Charge Input Capacitance Output Capacitance Reverse Transfer Capacitance Turn-On Time Turn-Off Time Symbol Conditions Min.
