SMD code 000 in SOT-23-6
Marking codes are not standardised, and the same code is reused by unrelated makers for unrelated parts. Below is every part in our tables printed with it, and any printed with a code that is easy to misread as it, from the manufacturers' own marking tables and published code lists.
000 on a chip resistor
0 Ω
Zero-ohm link
A zero-ohm link: a jumper in a resistor body, used to bridge a track or select an option. It is not a failed part.
Check it with a meter
Measure across it on the lowest ohms range: a link reads under an ohm. If it reads open, the link itself has failed, which does happen when it has been used as a fuse. Then something after it drew too much: find that before bridging it again.
On a transistor or diode body (SOT-23-5, DFN, SOT-89), 000 is a part code instead. Those parts are listed below.

Is it dead?
Voltage with the board powered; ohms from each pin to ground with it off.
Working, it reads
Supply pin at its voltage and the output doing what the datasheet says. Readings between pins depend on the part.
Dead, it reads
- A pin near 0 Ω to ground or to the supply pin where an identical part does not read that: failed short.
- Supply present, output stuck: failed, or its load has.
- On the board:
- A pin shorted to ground on the board can be anything on that net. Lift the pin to be sure.
- Compare:
- The surest reference is the same IC on a working board, measured pin by pin.
- Watch for:
- Its protection diodes can read like junctions between pins, even like a transistor. That proves nothing either way.
A dead part still carries its marking. A short or an open says it has failed, not that it is a different part.
Was it this one?
Printed with a code easy to misread as 000
One character differs, and it is one that is easy to confuse under a lamp. Each code has a page of its own.
Codes that begin with 000
For a marking with its end worn or burnt off. Each code has a page of its own.
