Do you know where the "Schottky" in the SS14 Schottky barrier diode comes from?

It actually originates from a physicist named Walter H. Schottky, who invented it. Unlike conventional diodes using a P-N junction, the SS14 Schottky barrier diode is uniquely crafted based on the direct contact between a metal and a semiconductor.

The SS14 diode is crucial for rectification and circuit protection. It allows current to flow in only one direction, effectively preventing short circuits and protecting the system. Thanks to its compact structure and small footprint, the SS14 fits perfectly into various modern devices, making it a go-to choice for global buyers.

Now, here comes the most critical question: Do you know how to judge if an SS14 diode is good or bad?

First, identify the polarity - the end marked with a white line is the cathode (negative). Set your multimeter to the diode test position and connect the probes:

• The Good Sign: In the forward direction (red probe to positive, black to negative), a good diode will show a regular voltage reading. When reversed, it must block current and display "1" or "OL".

• The Bad Sign: If it displays "1" or "OL" in both directions, or shows a reading/beeping when reversed, the diode is damaged.

As a leading China SS14 diode manufacturer, WEET specializes in high-quality diode manufacturing. Feel free to contact us anytime for your sourcing needs!

Tomb Sweeping Day Holiday Notice

Dear Partners & Valued Customers,

• Holiday Period: April 4th – 6th, 2026 (3 days)

• Back to Work: April 7th, 2026 (Tuesday)

On a computer motherboard, the WEET ROHS BAV99 diode is often used in RGB signal circuits.

It is composed of two series-connected diodes, with one end connected to the power supply and the other grounded. 

It mainly provides two functions: amplitude limiting and circuit protection.

• It limits the signal amplitude in the circuit to ensure that the signal is transmitted within a reasonable range.

• As the later stage is the signal output terminal, the ROHS BAV99 diode can protect the circuit from damage in case of external power abnormalities.

The circuit adopts an emitter-follower structure. The voltage remains basically stable during operation, and the current is mainly amplified to improve the overall driving capability. That is because the standard amplitude of the CVBS signal is fixed at 0.7Vpp, and the sync signal is 1Vpp, which requires sufficient driving capability to ensure stable output.

In terms of interface protection, BAV99 works with ordinary diodes. Two 1N4148 diodes can be used together to replace BAV99, but BAV99 has smaller capacitance and lower signal loss, making it more suitable for the protection and amplitude limiting of high-frequency interfaces.

The above is the function of WEET ROHS BAV99 diode in computer motherboards. Please feel free to contact WEET if you have any needs.

M7 is the SMA DO-214AC package of 1N4007. It is an ordinary rectifier diode with withstand voltage of 1000V and maximum average forward rectified current of 1A. Commonly used in AC220V rectifier circuit.

What can be used to replace rectifier diode M7?What are the parameters of chip diode M7 and what tube can be used to replace it? What types of diodes are M7 SMD diodes common to? What is the difference between chip rectifier diode M7 and A7? Rectifier diodes can be made of semiconductor germanium or silicon. M7 and A7 are silicon rectifier diodes with unidirectional conductivity, high breakdown voltage, low reverse leakage current and good high temperature performance. Generally speaking, the rectifier diode with high reverse voltage can replace the rectifier diode with low reverse voltage, and the diode with high rectifier current value can replace the diode with low rectifier current value. For example, M7 diodes can replace M6, M5, M4, m3, M2 and M1, and A7 patch diodes can replace A6, A5, A4, A3, A2 and A1.

The difference between chip diode M7 and A7 is as follows:

Detailed parameters of SMD M7 diode

Package form: do-214ac (SMA)

Average forward current: 1A

Reverse repetitive peak voltage: 1000V

Forward (non repetitive) surge current: 30A

Forward peak voltage: 1V

Reverse leakage current: 5ua, 50ua

Junction temperature: - 55 ° C to + 125 ° C

Storage temperature: - 55 ° C to + 150 ° C

Detailed parameters of chip A7 diode

Package form: sod-123fl

Average forward current: 1A

Reverse repetitive peak voltage: 1000V

Forward (non repetitive) surge current: 25A

Forward peak voltage: 1.1V

Reverse leakage current: 5ua, 50ua

Junction temperature: - 55 ° C to + 150 ° C

Storage temperature: - 55 ° C to + 150 ° C

Difference between diode M7 and A7

It can be seen from the above parameter details that the biggest difference between M7 and A7 lies in the packaging form. The diode M7 package is SMA / DO-214AC, the diode A7 package is sod-123FL, and the volume of M7 is larger than A7. The forward non repetitive surge current of M7 is 5A larger than that of A7, and the junction temperature difference is 5 ° C. The main difference between M7 and A7 is the packaging form. In practical application, diodes M7 and A7 can replace each other!
