MXP1144

MXP1144 SANTA ANA DIVISION Photovoltaic By-Pass Diode 50 Volts, 1.0 Amps P RODUCT P REVIEW KEY FEATURES DESCRIPTION W W W. Microsemi . COM Large area diode chip for medium current photovoltaic bypass applications, or for higher current hybrid applications. The device is rated for 1A for applications where the device will be exposed to substantial radiation flux (space). For other applications, it may be operated at higher currents. A version with attached leads is available. Oxide passivated structure for very low leakage currents Epitaxial structure minimizes forward voltage drop Triangular shape to fit in corner near flat of photovoltaic cell Forward voltage decreases with radiation exposure Targeted for terrestrial applications with silicon photovoltaic cells Thin construction for fit with photovoltaic cells APPLICATIONS/BENEFITS APPLICATIONS/BENEFIT APPLICATIONS/BENEFITS Increases efficiency of photovoltaic arrays Protects photovoltaic cells from reverse voltage IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com MAXIMUM RATINGS @ 25°C (UNLESS OTHERWISE SPECIFIED) Description Peak Repetitive Reverse Voltage W orking Peak Reverse Voltage DC Blocking Voltage Average Rectified Forward Current, Tc≤ 135°C Junction Temperature Range Storage Temperature Range Symbol VRRM VRWM VR IF(ave) Tj Tstg Max. 50 50 50 1.0 -65 to +150 -65 to +200 Unit Volts Volts Volts Amps °C °C ELECTRICAL PARAMETERS Description Reverse (Leakage) Current (in dark) Forward Voltage pulse test, pw= 300 µs Junction Capacitance Breakdown Voltage Symbol IR25 IR25 VF1 VF2 Cj1 BVR Conditions VR= 4 Vdc, Ta= 25°C VR= 50 Vdc, Ta= 25°C IF= 400 mA, Ta= 25°C IF= 1.0 A, Ta= 25°C VR= 4 Vdc IR= 200 µA, Ta= 25°C Min Typ. 10 20 750 770 1050 90 Max 200 775 800 1300 Unit nA nA mV mV pF V MXP1144 MXP1144 50 Copyright  2002 MXP1144.PDF, 2002-05-01 Microsemi Santa Ana Division 2830 South Fairview, Santa Ana, CA. 92704, 714-979-8220, Fax: 714-557-5989 Page 1 MXP1144 SANTA ANA DIVISION Photovoltaic By-Pass Diode 50 Volts, 1.0 Amps P RODUCT P REVIEW Mechanical Outline W W W.
