SMD code S10A
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.

Is it dead? One meter test per kind
Parts of the same kind are tested the same way, so each test is here once. Each part above points to its own.
Silicon diode
Diode range, part lifted or one leg off the pad. Red probe on the anode.
Working, it reads
About 0.5 to 0.8 V anode to cathode, and open the other way. Small switching diodes read about 0.6 to 0.7 V; large rectifiers can read a little lower.
Dead, it reads
- The same reading both ways round, near 0 V with a continuous beep or the same middling value: shorted.
- Open both ways: failed open.
- A reading the wrong way round as well: leaky.
- On the board
- this is a first look only: the meter reads every path between those pins, and a short can be a neighbour. Lift one leg before you condemn it.
- Compare:
- If an identical part sits elsewhere on the board, measure it the same way: that is what this one should read.
- Watch for:
- A three-pin body can hold two diodes. With a common pin they read two junctions from that pin, just like a transistor; in series they read two drops end to end. Test each pair the datasheet names.
A dead part still carries its marking. A short or an open says it has failed, not that it is a different part.
Ceramic capacitor
Ohms range across it, and a capacitance range with it lifted.
Working, it reads
On the ohms range it reads open, or climbs to open as it charges. Lifted, a capacitance range reads close to its value.
Dead, it reads
- Near 0 Ω, or a few ohms: shorted. The usual failure, often from a crack caused by board flex or heat, and it can come and go.
- A steady resistance, kilohms rather than open: cracked and leaking.
- Lifted, far below its value on a capacitance range: cracked open or drifted. Less common than a short, but it happens.
- On the board
- a shorted capacitor shorts its whole rail, so every capacitor on that rail reads the same short. Lift one end, or feed the rail from a current-limited supply and feel which part warms up.
- Compare:
- Chip capacitors are mostly unmarked, so the value comes from the schematic or the same position on a working board.
A dead part still carries its marking. A short or an open says it has failed, not that it is a different part.
Printed with a code easy to misread as S10A
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 S10A
For a marking with its end worn or burnt off. Each code has a page of its own.
