Fast-recovery Schottky for switching supplies
The STMicroelectronics TMBYV10-60FILM is a 60 V, 1 A Schottky rectifier rated for fast recovery (≤500 ns at >200 mA), making it a fit for high-frequency rectification in DC-DC converters, flyback diodes, and OR-ing circuits rather than 50/60 Hz line rectification where recovery time is irrelevant.
The 60 V reverse voltage (Vr) and 1 A average forward current (Io) define the application window: this diode suits 12 V, 24 V, and 48 V rails with adequate derating, but not 60 V rails where the margin disappears. Forward voltage is 700 mV max at 1 A, which sets the conduction loss at that current. Reverse leakage is 500 µA at 60 V – a typical Schottky trade-off: higher leakage than a PN-junction, but lower Vf. At elevated junction temperatures leakage rises and can dominate the thermal budget if the diode runs near its 125 °C limit.
MELF package – footprint and rework
The DO-213AB MELF (Metal Electrode Leadless Face) package is a cylindrical body with metallised end caps – no leads, no gull-wings. The pad layout must match the MELF footprint (wider than an SOD-123 pad) to avoid tombstoning during reflow. The cylindrical shape can roll during placement if the vacuum nozzle is not centred; a cut-tape or tray feed is more reliable than loose bulk.
ROHS3 compliant.
