Dear Partners & Valued Customers,

We would like to inform you of our holiday arrangement for Tomb Sweeping Day:

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

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

During the holiday, order handling, shipping and inquiries will be suspended. We will process all matters promptly after we return.

Please kindly arrange your orders and logistics in advance. We apologize for any inconvenience caused and appreciate your understanding.

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.
