PAD/JPAD/SSTPAD Series Vishay Siliconix Low-Leakage Pico-Amp Diodes PAD1 JPAD5 SSTPAD5 PAD5 JPAD50 SSTPAD100 PAD50 PRODUCT SUMMARY Part Number IR Max (pA) PAD1 –1 PAD5/JPAD5/SSTPAD5 –5 PAD50/JPAD50 –50 SSTPAD100 –100 FEATURES BENEFITS APPLICATIONS D Ultralow Leakage: PAD1 <1 pA D Ultralow Capacitance: PAD1 <0.8 pF D Two-Leaded Package D Negligible Circuit Leakage Contribution D Circuit “Transparent” Except to Shunt High-Frequency Spikes D Simplicity of Operation D Op Amp Input Protection D Multiplexer Overvoltage Protection DESCRIPTION The PAD/JPAD/SSTPAD series of extremely low-leakage diodes provides a superior alternative to conventional diode technology when reverse current (leakage) must be minimized. They feature leakage currents ranging from –1 pA (PAD1) to –100 pA (SSTPAD100) to support a wide range of applications. These devices are well suited for use in applications such as input protection for operational amplifiers. TO-206AA (TO-18) Modified TO-206AF (TO-72) Modified C The hermetically sealed TO-206AF (TO-72) package allows full military processing per MIL-S-19500 (see Military Information). The TO-226A (TO-92) plastic package provides a low-cost option. The TO-236 (SOT-23) package provides surface-mount capability. Both J and SST series are available in tape-and-reel for automated assembly. (See Packaging Information.)
