DPAD2 LOW LEAKAGE PICO-AMP DUAL DIODE Linear Systems replaces discontinued Siliconix DPAD2 The DPAD2 is a low leakage Monolithic Dual Pico-Amp Diode The DPAD2 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 DPAD2 features a leakage current of -2 pA and is well suited for use in applications such as input protection for operational amplifiers. DPAD2 Benefits: Negligible Circuit Leakage Contribution Circuit “Transparent” Except to Shunt High-Frequency Spikes Simplicity of Operation DPAD2 Applications: Op Amp Input Protection Multiplexer Overvoltage Protection FEATURES DIRECT REPLACEMENT FOR SILICONIX DPAD2 HIGH ON ISOLATION EXCELLENT CAPACITANCE MATCHING ULTRALOW LEAKAGE REVERSE BREAKDOWN VOLTAGE REVERSE CAPACITANCE ABSOLUTE MAXIMUM RATINGS @ 25°C (unless otherwise noted) 20fA ∆CR ≤ 0.5pF ≤ 2 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) DPAD2 ELECTRICAL CHARACTERISTICS @ 25°C (unless otherwise noted) SYMBOL CHARACTERISTICS MIN.
