RF302LAM2STFTR Discrete Semiconductor Products

The RF302LAM2STFTR is an integrated Schottky power rectifier. It is primarily used in applications requiring low-forward voltage drop and reverse-recovery characteristics. The RF302LAM2STFTR is an integrated surface-mount Schottky rectifier, incorporating a dual diode in a single package.

The RF302LAM2STFTR has an adjustable on-state reverse leakage current characteristic and effective in-circuit ESD protection. It is also used in clamped inductive loads and low power supply circuits as well as for general circuit protection. Its peak reverse voltage rating is 30V, and it has a maximum power dissipation of 1W.

Application Field

The most important application of the RF302LAM2STFTR is in power supply rectification and circuit protection. It is often used for ripple reduction, inrush current and reverse surge current applications. It is also used for preventing electromagnetic interference (EMI) and harmonic distortion.

The RF302LAM2STFTR is particularly suitable for high-frequency DC-DC converters, low-power switching power supplies, inverters, phase-control, and PFC rectification applications. It is suitable for use in high-efficiency, high-frequency circuits and in voltage clamping circuits.

Additionally, the RF302LAM2STFTR can be used to improve low-current rectification in applications such as receivers, mobile phone power supplies, and power amplifiers.

Working Principle

The RF302LAM2STFTR is a single-diode power rectifier with an adjustable on-state reverse leakage current characteristic, an effective in-circuit ESD protection, and a reverse trans-resistance of less than 1Ω. It also has a very low forward-voltage drop, as well as an enhanced temperature coefficient.

When the P-side of the rectifier is connected to the power source, the electrons are forced to flow through the junction and deposit at the N-side of the diode. This flow of electrons creates a barrier between the P-side and the N-side, essentially blocking the reverse current while allowing forward current to pass. This mechanism is essentially how the RF302LAM2STFTR operates to convert AC signal to DC.

The RF302LAM2STFTR can be used for a wide variety of circuit protection applications, such as in clamped inductive loads and low-power supply circuits. Its adjustable on-state reverse leakage current characteristic allows for higher performance and improved circuit protection.
