Hi to all,

I have a question with the next component: Diodes BAV99DW-7-F.

According with the data, it is a SOT-363 package.

When I start creating the component with PCBLibraries I don't know if it is a SOT-23 package with outward L lead or a SOP with L lead.

For example, for NXP the SOT363  is a TSSOP6.

I checked the footprint in both cases 
- SOP6P65_200X210X110L32X20N
- SOT23-P65_210X110L32X20N

and they are similar
 S=1.15mm L=0.79mm, W=0.37mm

I know that both packages come from the JEITA SC-88, but if I create it using a SOT23 model or a SOP model the final name of the footprint is different and it could create problems.

Has anyone had any similar experience?

Thanks to all for your comments.

TSSOP = Thin Shrink Small Outline Package 

Thin = What? Who decides what Thin is? 

Shrink = Fine Pitch. What is "Fine Pitch" today? 

TSSOP is a mfr. created marketing name because they want to promote their Thin Fine Pitch package. 

In today's reality, it's just an SOP, which is an Integrated Circuit. 

SOT = Small Outline Transistor. 

Every NXP Case Code starts with SOT. It's their way for creating a Case Code ID. They're not all Transistors, most of them are semiconductors. It's just a Case Code.

Hi Tom,

Thanks for sharing your Knowledge!!!  Smile

In my particulary situation with the diode BAV99DW-7-F, I will use the SOP model instead the SOT only because SOT has the word transistor and the compnent is not a transistor and SOP is more generic name: "Small Outline Package".

Best regards.
