70 V, 70 mA Schottky in an SC-80 — what this diode is for
The Infineon BAS7002WH6327 is a Schottky signal diode in a PG-SCD80-2 surface-mount package, rated for 70 V DC reverse voltage and 70 mA average rectified current. Its 100 ps reverse recovery time and 1.5 pF capacitance at 0 V bias make it a fit for high-speed clamping, detection, and switching circuits where a standard PN-junction diode would be too slow or leaky.
100 ps trr and 1.5 pF — the high-speed story
The 100 ps reverse recovery time is the headline number here — it means this diode can switch at UHF frequencies without storing charge, which is what you need for RF detector stages, mixer protection, or fast logic-level clamping. The 1.5 pF capacitance at 0 V bias keeps the diode from loading a high-impedance node, so it works as a shunt protector on a 50 Ω transmission line without degrading return loss. Forward voltage is 1 V at 15 mA, typical for a Schottky of this current class, and reverse leakage is 100 nA at 50 V — low enough for battery-powered sense circuits.
For small quantities or prototype runs, the SC-80 package is easy to hand-solder with a fine-tip iron, and the part is RoHS-compliant per Infineon's standard lead-free plating.
