1.0A 1000V surface mount silicon rectifier M7 for general purpose
Description:
A diode is a one-way valve for electricity. Diodes allow flow of electricity in one direction. Most diodes have a painted line on one end showing the direction or flow. The negative side is normally white.
An SMT component is usually smaller than its through-hole counterpart because it has either smaller leads or no leads at all. It may have short pins or leads of various styles, flat contacts, a matrix of solder balls (BGAs), or terminations on the body of the component.
Features:
• Ideal for surface mount application
• Surge overload rating to 30A peak
• Plastic material has UL recognition flammability classification 94V-0
• Build-in strain relief
Application:
• Can be used to prevent reverse polarity problem
• Half Wave and Full Wave rectifiers
• Used as a protection device
• Current flow regulators
Maximum Ratings & Thermal Characteristics:
Rating at 25℃ ambient temperature unless otherwise specified, Resistive or Inductive load, 60 Hz.
For Capacitive load derate current by 20%.

Difference between diode and rectifier:
| Diode | Rectifier | |
| Definition | A diode is a type of electrical device that allows the current to move through it in only one direction. | Rectifiers are electronic devices that are used for converting AC voltage into unidirectional pulsating DC voltage. Diodes are often used in the design of rectifiers. |
| Uses | • Clipping and Clamping - to protect the circuits by putting limitations on the voltage • Voltage rectifier – Turing AC into DC • Voltage Multipliers • Non-linear mixing of two voltages |
• They can be found regulating the power in computers and the electrical power in motor vehicles. • They can also be used in battery chargers for rechargeable batteries, computer power supplies and vehicle batteries. • Often used for AC to DC conversion, • Can also be used in the detector of radios in order to perform radio demodulation. |
| Types | • Junction diode (ordinary type) • Light emitting (LED) • Photodiodes (absorbs light, gives current) • Schottky (high speed switch, low turn on voltage, Al. on Silicon) • Tunnel (I vs. V slightly different than jd's, negative resistance!) • Veractor (junction cap. varies with voltage) • Zener (special junction diode, use reversed biased) |
• Half-wave rectifier - It is the simplest type of rectifier, which is made with just one diode. • Full-wave rectifier - This rectifier is essentially made of two half-wave rectifiers, and can be made with two diodes and an earthed center tap on the transformer. • Bridge rectifier - It makes use of four diodes in a bridge arrangement to achieve full-wave rectification. |
| Device type | A diode only has 2 semi conductive regions, and therefore has 2 leads. | A rectifier assembly generally has multiple diodes, or more than two terminations. |
