The voiceless postalveolar affricate is a quite common sound cross-linguistically. It often arises from t before a high vowel or j. Its voiced equivalent is dʒ. It can also be ejective, tʃʼ.
In X-SAMPA it can be represented explicitly as [t_S], though for convenience it can also be represented as [tS]. The disjunctor hyphen (thus [t-S]) can be used when it is important to emphasize the separateness of the [t] and the [S].
Americanistic, Uralistic etc. linguistic traditions use the symbol č for this sound.
Note that in shallow transcrition it is common to use /tʃ/ as a catch-all symbol for a number of different affricates, such as the voiceless retroflex affricate [tʂ], voiceless palato-alveolar affricate [tɕ], or even the voiceless palatal affricate [cç], if they do not contrast in the language in question with an actual postalveolar.
