Small-signal Schottky for high-speed switching and protection
The Infineon BAS-70-02WE6327 is a small-signal Schottky diode in a PG-SCD80-2 surface-mount package, rated for 70 V reverse voltage and 70 mA average rectified current. Its 100 ps reverse recovery time and 1.5 pF junction capacitance at 0 V make it a natural fit for high-speed switching, RF detector circuits, and low-voltage clamping protection in portable and telecom gear. The 1 V forward voltage at 15 mA is typical for a Schottky of this current class, and the 100 nA reverse leakage at 50 V keeps standby power low.
The 70 V reverse voltage covers most 12 V and 24 V rails with plenty of derating margin for inductive kickback or transient spikes. The 70 mA average current rating suits signal-level switching and gate-drive bootstrap circuits, not power rectification. If your design needs to switch a 100 mA load or block 80 V, this is not the part — step up to a higher-current Schottky like the BAS70-04 series or a 100 V rated device. The 100 ps trr and 1.5 pF capacitance mean this diode introduces minimal delay and capacitive loading on a high-speed data line or RF path. It works well as a protection clamp on I/O lines up to a few hundred MHz, or as a mixer diode in low-power RF receivers.
Lifecycle and supply
For dual-sourcing flexibility, the BAS70-02W E6327 is a functional equivalent — same Schottky type, same 70 V / 70 mA ratings, same 100 ps trr, and same PG-SCD80-2 footprint. The main difference is the ordering code suffix; the parametric performance is identical.
