Power transformation
Specifications for a railway power transformation system, in the "redresseur" section:
"Les diodes employées sont des diodes à pression du type: (1) tension inverse de crête non répétitive, (2) etc."
Looked easy, but I am a bit concerned by the conspicuous absence of "diode à pression" and "pressure diode" (tout court) from Google.
Can anyone shed any light?

stud diode
I have t give this low conf. as I haven't got the time to check it out for you right now, but this looks suspiciously like an EN > FR translation error in the first place!
'stud diode' is certainly a very common type, referring to the metal package used for such high-power devices.
And I believe someone has perhaps mis-translated the original EN term, thinking of it like a 'press-stud'!!

It would probably help to confirm if you have the/a type number of the diodes in question?

Shame, that would have helped!
Maybe you could post the rest of the diode specs., that should help to narrow it down a bit...?

Here is a page from Radiospares that illustartes one of the countless different types of 'stud diodes' — unfortunately, I have so far been unable to find a FR site that actually uses a word for them!

Note from asker:
| No type numbers, I'm afraid. |
| Full specifications for the diodes: 6.2-Dimensionnement des diodes Compte tenu des niveaux de tension, entre d’une part, deux phases du secondaire du transformateur, et d’autre part entre la caténaire et les rails de roulement, la tension inverse limite de pointes répétitives (V RRM) des diodes ne devra pas être inférieure à 2400V. Si chaque bras du pont de Graetz comporte au moins deux diodes en parallèle, le constructeur indiquera les déséquilibres maximaux admissibles entre diodes pour : • le régime de base • le régime de charge temporaire 1 mm. La valeur maximale admissible du déséquilibre entre diodes ne sera pas supérieure à 15%par rapport à la moyenne pour le régime de base. Compte tenu du déséquilibre et quel que soit le régime de charge spécifié, la température de jonction des diodes sera inférieure à la valeur garantie de température maximale de jonction (TVJ) que les diodes peuvent tenir en permanence. 6.3-Niveaux d’isolement Les isolements devront tenir : • Une tension appliquée de 10kV -50Hz -1mm entre, d’une part les circuits de puissance, et d’autre part les circuits auxiliaires réunis à la masse, • Une tension appliquée de 2,5kV -50Hz -1mm entre les circuits auxiliaires BT et la masse. 6.4 -Type et caractéristiques des diodes Les diodes employées sont des diodes à pression du type : • Tension inverse de crête non répétitive : V • Tension inverse de crête admissible en permanence : V • Courant de crête admissible pendant 10 ms sans tension réappliquée : A • Courant de crête admissible pendant 200 ms pour 50% de tension réappliquée : A • Température maximale admissible pour la jonction : °C • La chute de tension directe est comprise entre (1 pulse sinusoïdale par seconde de 3300A crête, durée 10 ms) : V et V • Stabilité en courant de blocage : la variation de la valeur du courant inverse ne doit pas dépasser...........mA pour une température de 150°C maintenue pendant 4h sous une tension inverse appliquée de ........... V |

I am sending this in because I found "pressure diode" on its own.

: Nice find, but irrelevant in this context, since your ref. is clearly talking about a specialized pressure measurement system, and the collocation 'pressure diode' is just fortuitous.
