Small-signal Schottky array for high-speed switching
The Infineon BAS7004SH6827XTSA1 is a Schottky diode array configured as two series-connected pairs in a single SOT-363 package.
What the key specs mean for the BOM
The 100 ps reverse recovery time (trr) is the headline figure here — it means the diode switches off almost instantaneously, with negligible stored charge to sweep out. This makes the array suitable for high-speed signal clamping, RF detector circuits, and protection networks where a standard PN-junction diode would ring or slow the edge rate. Forward voltage is 1 V max at 15 mA, which is typical for a small-signal Schottky. The 100 nA reverse leakage at 50 V is low enough for battery-powered sense circuits, though note that Schottky leakage rises exponentially with junction temperature — at 125 °C it will be orders of magnitude higher, so budget accordingly in hot environments. The 2-pair series configuration (two diodes in series per leg) gives a combined reverse standoff of 140 V across each series string, while the centre tap allows the array to be used as a dual-series clamp or a bridge leg.
The base product number is BAS7004, and the suffix SH6827 denotes the specific reel packaging variant.
