SMTY18AM Datasheet | STMicroelectronics

FEATURES AND BENEFITS - - - - - - High peak pulse power: 400W (8/20µs) Stand-off voltage 16V Low forward voltage: 0.48V @ 0.85A @ 25°C Low clamping factor VCL/VBR Fast response time Very thin package (1.0mm overall ponent height) STmite (DO-216AA) DESCRIPTION The Transky™ is designed specifically for portable equipments and miniaturized electronics devices subject to ESD transient overvoltages. The Transky™ bines the performance of a Transil™ or TVS (Tansient Voltage Supressor) and low forward voltage Schottky diode in a monolithic structure.
