LSDPAD1 LOW LEAKAGE PICO-AMP DUAL DIODE Linear Systems replaces discontinued Siliconix LSDPAD1 The LSDPAD1 is a low leakage Monolithic Dual Pico-Amp Diode The LSDPAD1 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 LSDPAD1 features a leakage current of -1 pA and is well suited for use in applications such as input protection for operational amplifiers. LSDPAD1 Benefits: Negligible Circuit Leakage Contribution Circuit “Transparent” Except to Shunt High-Frequency Spikes Simplicity of Operation LSDPAD1 Applications: Op Amp Input Protection Multiplexer Overvoltage Protection FEATURES DIRECT REPLACEMENT FOR SILICONIX LSDPAD1 HIGH ON ISOLATION EXCELLENT CAPACITANCE MATCHING ULTRALOW LEAKAGE REVERSE BREAKDOWN VOLTAGE REVERSE CAPACITANCE ABSOLUTE MAXIMUM RATINGS @ 25°C (unless otherwise noted) 20fA ∆CR ≤ 0.2pF ≤ 1 pA BVR ≥ ‐45V Crss ≤ 0.8pF Maximum Temperatures Storage Temperature Operating Junction Temperature Maximum Power Dissipation Continuous Power Dissipation MAXIMUM CURRENT Forward Current (Note 1) ‐65°C to +150°C ‐55°C to +135°C 500mW 50mA Click To Buy LSDPAD1 ELECTRICAL CHARACTERISTICS @ 25°C (unless otherwise noted) SYMBOL CHARACTERISTICS MIN.
