BAT54C,215

BAT54C,215 is the full orderable part number for the Nexperia BAT54C dual common-cathode Schottky diode in SOT-23 (TO-236AB), package marking W1, verified word-for-word on the maker’s chemical-content page at build time: orderable part BAT54C,215, 12NC 933976370215, package SOT23 (TO-236AB), state RFS (released for supply); the maker’s packing table gives the -215 element as the 3,000-piece tape-and-reel form and the -235 element as the 10,000-piece form. Verified figures per diode: reverse voltage of 30 V maximum, forward current of 200 mA maximum, surge current of 600 mA maximum, forward voltage maxima of 240 mV at 0.1 mA, 320 mV at 1 mA, 400 mV at 10 mA, 500 mV at 30 mA and 800 mV at 100 mA, reverse current of 2 µA maximum at 25 V, diode capacitance of 10 pF maximum, reverse recovery time of 5 ns maximum, and total power dissipation of 250 mW maximum. The selection point is a low-forward-drop clamp and OR-ing pair whose common-cathode wiring suits rail clamping and signal steering. Selection advice: the BAT54 family’s letter is the wiring diagram — the C common-cathode arrangement is this code, and the A and S arrangements are separate order codes; quote the full BAT54C,215 string. Parameters verified against the Nexperia BAT54 series datasheet and the maker’s chemical-content listing.
