SOT-363 (SC-88) Component Package

Overview

SOT-363 is used for smaller SMD transistors and MOSFETs (up to 2 per package).

It has a body width of 1.25mm and a length of 2.0mm. This package seems identical to the SOT-323-6. However I have kept this page separate from the SOT-323-6 since I could not find conclusive evidence that they are identical.

Here is a comparison of major dimensions between the SOT-363 and SOT-323-6:

Dimensions for the SOT-363 were from NXP¹. Dimensions for the SOT-323-6 were from Analog Devices². All values typical.

Footprint (Land Pattern)

Thermal Resistance

• \(R_{\theta JA} = 435^{\circ}/W\) (FR-4, single-sided, 1oz. copper, minimum recommended pad layout)
• \(R_{\theta JA} = 330^{\circ}/W\) (FR-4, double-sided, 2oz. copper, 1 inch square copper pad layout)
• \(R_{\theta JC} = 139^{\circ}/W\)

Polarity

Some components using the SOT-363 package do not require any polarity marking as the pins are rotationally symmetric. This is a common configuration for a two-device MOSFET component, in where the pinout is shown below:
