Package name: jsl/landpatterns/SOT

Small Outline Transistor Packages

The SOT package is a dual-row SMT package similar to the SON. The leads are typically gull-wing style.

There are many popular packages including:

1. SOT-23-3 - 3-pin popular for diodes and transistors
2. SOT-23-6 - Similar to SOT-23-3 but with full pin accoutrement.
3. SOT-23-5 - Similar to SOT-23-6 but missing one pin.

Thermal leads are uncommon in this package style.

TODO - Diagram here of SOT style packages.

Definitions

SOT-Lead

Small Outline Transistor (SOT) Lead Type

public defstruct SOT-Lead <: SMT-Lead :

This type defines the parameters of each of the individual leads of the IC package. It is typically used with Lead-Profile

Constructors

SOT-Lead

Constructor for defstruct SOT-Lead

public defn SOT-Lead (lead-type:LeadProtrusion, length:Toleranced, width:Toleranced)

SOT-Lead

Constructor for defstruct SOT-Lead

public defn SOT-Lead ( -- lead-type:LeadProtrusion = ?, length:Toleranced, width:Toleranced)

SOT

SOT Package Type

public defstruct SOT <: Dual-Package :

This type defines the features of the dual-row Small Outline Transistor (SOT) type of package.

Note that the base implementation is targeted towards the full SOT. To implement non-symmetric SOT packages see SOT-23-3 and SOT-23-5

Constructors

SOT

Constructor for defstruct SOT

public defn SOT ( -- num-leads:Int, lead-profile:Lead-Profile, thermal-lead?:False|Shape|ThermalPad = ?, package-body:PackageBody, pad-planner:PadPlanner = ?, lead-numbering:Numbering, density-level:DensityLevel = ?)

Functions

SOT

public defn SOT ( -- num-leads:Int, lead-profile:Lead-Profile, thermal-lead?:False|Shape|ThermalPad = ?, package-body:PackageBody, pad-planner:PadPlanner = ?, num-scheme:Numbering = ?, density-level:DensityLevel = ?) -> SOT

• Returns SOT

SOT-23-5

5-pin SOT-23 Package

public defn SOT-23-5 ( -- lead-profile:Lead-Profile, package-body:PackageBody, density-level:DensityLevel = ?) -> SOT

• lead-profile: Lead-Profile - Typically the user would use a SOT-Lead instance here to define the leads for the package.
• package-body: PackageBody - Dimensions for the body of the package.
• density-level: DensityLevel - Density rating for the landpattern. Default is from DENSITY-LEVEL in design settings.
• Returns SOT

SOTFL-Lead

Small Outline Transistor Flat Lead (SOTFL) Type

public defstruct SOTFL-Lead <: SMT-Lead :

This type defines the parameters of each of the individual leads of the IC package. It is typically used with Lead-Profile

This supports packages like SOT-23F or SOT538 which use a flat lead style instead of the Gull-Wing Lead style.

Constructors

SOTFL-Lead

Constructor for defstruct SOTFL-Lead

public defn SOTFL-Lead (lead-type:LeadProtrusion, length:Toleranced, width:Toleranced)

SOTFL-Lead

Constructor for defstruct SOTFL-Lead

public defn SOTFL-Lead ( -- lead-type:LeadProtrusion = ?, length:Toleranced, width:Toleranced)

SOT23-5-PadPlanner

public defstruct SOT23-5-PadPlanner <: ShapePadPlanner :

Constructors

SOT23-5-PadPlanner

Constructor for defstruct SOT23-5-PadPlanner

public defn SOT23-5-PadPlanner (shaper:(Dims) -> Shape)

SOT-23-3

3-pin SOT-23 Package

public deftype SOT-23-3 <: SOT

This type customizes the SOT implementation to add a special L-shaped silkscreen outline. It additionally provides custom planner and numbering to support the 3-pins in non-standard numbering order.

Functions

SOT-23-pkg-outline

public defn SOT-23-pkg-outline (pkg:SOT-23-3, vp:VirtualLP -- line-width:Double = ?, mask-clearance:Double = ?, side:Side = ?)
