New Schottky diode series delivers enhanced single surge current

Vishay Electronic : 08 June, 2001  (New Product)
A new series of Schottky diodes providing superior capacitance, a low forward voltage drop, and a very high single surge current rating was announced today by Vishay Intertechnology, Inc. Devices in the Vishay Telefunken series will be used for MOS protection; for steering, biasing, and coupling functions in logic-level applications where fast switching is required; in dc-to-dc converters; and in low-current power supplies.
A new series of Schottky diodes providing superior capacitance, a low forward voltage drop, and a very high single surge current rating was announced today by Vishay Intertechnology, Inc. Devices in the Vishay Telefunken series will be used for MOS protection; for steering, biasing, and coupling functions in logic-level applications where fast switching is required; in dc-to-dc converters; and in low-current power supplies.

The 12 devices included in the new '103' series are offered in a range of breakdown voltages, 40 V (xx103A), 30 V (xx103B), and 20 V (xx103C), and in four standard package types: the DO35 (SD103x), MiniMELF (LL103x), QuadroMELF (LS103x), and MicroMELF (MCL103x).

Providing a power-efficient solution for designers of consumer and communications products, each of the new Schottky diodes features a low maximum forward voltage drop of 0.37 V at a 20-mA forward current, and a maximum leakage current of just 5 A at a reverse voltage of 30 V. Each device additionally is rated for a high single surge current of 15 A and a typical junction capacitance of 50 pF at a 1-MHz frequency. An integrated protection ring guards against static discharge.

The unique high surge current/low voltage capabilities of the new 103 series complements existing Vishay Telefunken Schottky offerings for low-current/high-voltage applications and simplifies the task of purchasers by making devices for a wide range of industrial standards and design needs available from one of the industry's most experienced manufacturers of glass-packaged diodes. Vishay ships more than 10 billion such devices annually.

Samples and production quantities of the Vishay Telefunken 103 Schottky diode series are available now, with lead times of up to 12 weeks for larger orders.
