The MMSD301T1G diode is a single phase, standard recovery diode, which is designed for use in low frequency and high frequency industrial, commercial and consumer applications. This device is available in a TO-236AB (SC-59) and in a SOT-223 (SMD) package.

The MMSD301T1G is a fast recovery, low forward voltage drop, silicon rectifier ideal for use in high current, low voltage applications. It is designed to provide high current rectification with excellent reverse bias characteristics and low forward voltages, making it ideal for use in a wide range of applications such as AC-DC power supplies, motor speed controllers and bridge rectifiers.

The MMSD301T1G diode features a built-in polarity protection, ensuring that the diode is never subjected to high voltage reverse bias conditions, and it has a junction temperature rating of 175°C. This device also features a low on-state voltage drop, as well as faster body diode recovery from its reverse bias state, making it suitable for high frequency AC circuits.

The MMSD301T1G is a general purpose, single rectifier with a maximum forwarding current rating of 3A and a reverse voltage rating of 100V. It also has a peak surge current rating of 6A and reverse recovery time (trr) of 18ns. The diode is designed for operating temperatures between -55C to 175C and has a maximum junction temperature rating of 175C.

The working principle of the MMSD301T1G is based on the P-N junction diode which prevents current from flowing in the reverse direction. When a voltage is applied to the Anode it allows current to flow from the cathode to the anode, resulting in forward current conduction, hence the concept of rectification. This action generally occurs at lower voltages in the forward bias direction, but is blocked in the reverse bias direction. This type of diode can be used in DC to AC conversion applications such as AC-DC power supplies, and Bridge Rectifier applications. When used in these types of applications, the diode will rectify the alternating current (AC) into direct current (DC).

The MMSD301T1G is ideal for rectifying higher AC line peak currents demanded by modern appliances, and it is also suitable for rectifying high peak currents in industrial applications. It is suitable for easy integration into a wide range of commercial and consumer AC-DC power supplies. The device is also highly reliable due to its low on-state voltage drop and fast body diode recovery time from its reverse bias state.

In summary, the MMSD301T1G is an ideal choice for low frequency and high frequency industrial, commercial and consumer applications. It is designed for use in high current, low voltage applications, providing excellent reverse bias characteristics and low forward voltages. The device features high surge current ratings and low on-state voltage drops, making it highly reliable and suitable for easy integration into AC-DC power supplies.
