Vishay's rectifiers and TVS in SMP package feature high 3A power rating and typical thermal resistance of 20°C/W in a 2mm x 3.8mm footprint.

Vishay's current package type for its rectifier and transient voltage suppressor (TVS) products delivers the same current and power ratings as the SMA package in a 49% smaller footprint.

These devices are aimed at power supply and power conversion applications in desktop and notebook PCs, servers, disk drives, mobile phones, PDAs, hybrid ICs, and automobile electronic sensors and control units, where the 1mm height and 2mm by 3.8mm footprint of the SMP package allows designers to reduce the size of power circuitry and thus enable more space efficient end products.

Designed for secondary rectification of AC-to-DC and DC-to-DC converters, freewheeling and polarity protection, they can handle voltages from 20V to 40V and maximum currents of 1A (device numbers SS1P3L and SS1P4L) and 2A (device numbers SS2P2, SS2P3, SS2P4, SS2P2L, and SS2P3L) and a 3A device, SS3P4. Featuring a very low forward voltage drop, these rectifiers improve power efficiency and generate less heat in end products, resulting in increased reliability and a higher comfort level during use.

The S1PB through S1PM standard rectifiers can handle 1A and 50V to 1000V of power, making them the optimal solution for general purpose rectification, polarity protection and rail-to-rail protection in automotive applications.

With 1A and 50V to 200V capabilities, these ultrafast rectifiers offer designers a choice of recovery times as fast as 15ns for computers and other consumer electronics applications (device numbers ES1PB through ES1PD) or low leakage currents for the high temperature automotive environment (device numbers ESH1PB through ESH1PD). Typical junction-to-case thermal resistance for all of the these products is a low 20°C/W.

Offering twice the power rating of the nearest competitor in a sub-SMA package, Vishay’s TVS devices in the SMP package can handle up to 400W with breakdown voltages from 13V to 43V. Used in consumer, computer, industrial and automotive applications, the new devices (TPSMP13 through TPSMP43A) are designed to protect ICs, transistors, signal lines of sensor units, and electronic units from electrostatic discharges, lightning surges and other transient voltages.

The single-chip, surface-mount SMP (DO-220AA) package of these rectifiers and TVS features solder pads that are compatible with other SMD devices, so no modification is needed to the PCB layout when they are used as higher-performing upgrades to existing devices.
