I wonder why <mosfet> doesn't have connections while <resistor> does?

## astrimid — 2026-07-11T15:12:43.445000+00:00

And what's the conceptual difference between connections property and <trace>?

connections and `<trace>` are almost the same , trace has some props like `name` that connections don't offer tho, and for the `<mosfet>` it should have them if not that is a bug, I will check the issue thanks for the report

Don't see connections anywhere in common props nor in mosfet props:

https://github.com/tscircuit/props/blob/a151076e871b7dc5dc2795a181c941a32f7dad35/lib/components/mosfet.ts#L8-L12
export interface MosfetProps<PinLabel extends string = string>
  extends CommonComponentProps<PinLabel> {
  channelType: "n" | "p"
  mosfetMode: "enhancement" | "depletion"
}

CommonComponentProps
export interface CommonComponentProps extends CommonLayoutProps {
  key?: any;
  name: string;
  pinAttributes?: Record<PinLabel, PinAttributeMap>;
  supplierPartNumbers?: SupplierPartNumbers;
  cadModel?: CadModelProp;
  children?: any;
  symbolName?: string;
  doNotPlace?: boolean;
  /**
   * This component will be drawn as part of this section e.g. "Power"
   */
  schSectionName?: string;
  /**
   * This component will be drawn as part of this sheet e.g. "Main"
   */
  schSheetName?: string;
}

is `pinAttributes` the property I need?

## astrimid — 2026-07-11T15:53:04.660000+00:00

So I should just use <trace>?

## Seve — 2026-07-11T16:39:52.999000+00:00

Just use trace for now, but will definitely introduce connections to mosfet! Fwiw trace is usually better because of the ability to name the net or sometimes specify a custom width

fwiw i THINK mosfet got connections today
