DISCRETE SEMICONDUCTORS DATA SHEET book, halfpage M3D153 BAV45 Picoampere diode Product specification Supersedes data of July 1986 1996 Mar 13 Philips Semiconductors Product specification Picoampere diode FEATURES • Extremely low leakage current: max. 5 pA • Low diode capacitance • Light insensitive. APPLICATION • Clamping • Holding • Peak follower • Time delay circuits • Logarithmic amplifiers • Protection of insulated gate field-effect transistors. Fig.1 k MAM207 BAV45 DESCRIPTION Silicon diode in a metal TO-18 can. It has an extremely low leakage current over a wide temperature range combined with a low capacitance and is not sensitive to light. a Simplified outline (SOT18/15; TO-18 except for the two leads) and symbol. CAUTION Handle the device with care whilst soldering into the circuit. The extremely low leakage current can only be guaranteed when the bottom is free from solder flux or other contaminations.
