Classification of TVS transient suppression diodes

TVS transient voltage suppressors, as electronic circuit overvoltage protection devices, are increasingly being accepted and applied by electronic design engineers.

But do you know what classification methods TVS has?

1. Series name+power

The most common TVS classification method currently is based on the series name and power.

The TVS product series of Ruyinte Electronics includes:

SMF 200W 、SMAJ 400W、SMBJ 600W、P6SMB 600W、P8SMB 800W、1.0SMB 1000W、SMCJ 1500W、SMDJ 3000W、5.0SMDJ-H Series 5000W、SM8 6600W、SA 500W、P6KE 600W、1.5KE 1500W、3KP 3000W、5KP 5000W、15KP 15000W Waiting for the TVS series.

2. Encapsulation

Electronic engineers often need to search for the corresponding packaged TVS when applying TVS. The packaging of Yintai Electronics' TVS and TVS ARRAY (ESD) products mainly includes:

Classified by packaging (SMD, THT)

SMA/DO-214AC、SMB/DO-214AA、SMC/DO-214AB、SMF/SOD-123FL、SM8/DO-218AB、P-600、DO-15、DO-27、SOD-323\523\723\882\923、DFN、SO-8、SOT23\SOT23-6L、SOT143\353\363\553\563、 0402 \ 0603 \ 0805 \ 1206 \ 1812 \ 2018 \ 2920, etc

And customized packaging and testing can be carried out according to customer needs.

3. Voltage and current

From the above TVS characteristic parameters, it can be inferred that TVS has three voltage parameters: VR, VBR, and VC, as well as three current parameters: IR, IT, and IPP.

The voltage of Yintai Electronics' TVS ranges from 3.3V to 400V, and electronic engineers select the TVS based on relevant parameters.

4. Polarity

According to TVS polarity, it can be divided into unidirectional and bidirectional TVS.

Yinte Electronic TVS is generally named as SMFxxxA in one direction, and SMFxxxCA in two directions.

5. Other

Other classification methods

Such as testing standards or waveforms, manufacturing processes, materials, packaging methods, number of pins, colors, operating temperatures, etc.
