LSDPAD50 LOW LEAKAGE PICO-AMP DUAL DIODE Linear Systems replaces discontinued Siliconix LSDPAD50 The LSDPAD50 is a low leakage Monolithic Dual Pico-Amp Diode The LSDPAD50 extremely low-leakage monolithic dual diode provides a superior alternative to conventional diode technology when reverse current (leakage) must be minimized. In addition the monolithic dual construction allows excellent capacitance matching per diode. The LSDPAD50 features a leakage current of 50 pA and is well suited for use in applications such as input protection for operational amplifiers. LSDPAD50 Benefits: Negligible Circuit Leakage Contribution Circuit "Transparent" Except to Shunt High-Frequency Spikes Simplicity of Operation LSDPAD50 Applications: FEATURES DIRECT REPLACEMENT FOR SILICONIX LSDPAD50 HIGH ON ISOLATION EXCELLENT CAPACITANCE MATCHING ULTRALOW LEAKAGE REVERSE BREAKDOWN VOLTAGE REVERSE CAPACITANCE ABSOLUTE MAXIMUM RATINGS @ 25C (unless otherwise noted) 20fA CR 0.5pF 50 pA BVR 45V Crss 2.0pF Maximum Temperatures Storage Temperature Operating Junction Temperature Maximum Power Dissipation Continuous Power Dissipation MAXIMUM CURRENT Forward Current (Note 1) 65C to +150C 55C to +135C 500mW 50mA Op Amp Input Protection Multiplexer Overvoltage Protection Click To Buy LSDPAD50 ELECTRICAL CHARACTERISTICS @ 25C (unless otherwise noted) SYMBOL CHARACTERISTICS MIN.
