Scrs Procurement Notes
Verify the specific ordering suffix when purchasing. The PbF designation indicates lead-free and RoHS compliance. Confirm that the required voltage rating matches the application needs, as the series includes variants with different voltage ratings. Ensure thermal management aligns with the specified junction temperature limits during operation.
Scrs Selection Notes
Select this component for medium power switching and phase control applications requiring high voltage blocking capabilities. Consider the 1200 V rating for high-voltage AC environments. Evaluate thermal resistance requirements based on the expected conduction angle and ambient conditions to ensure the junction temperature remains within safe operating limits.
Scrs Part Context
This part belongs to the VS-25TTS..PbF Series, which covers high voltage phase control thyristors rated at 25 A. The series includes variants with different voltage ratings, such as 800 V and 1200 V options. These devices are silicon controlled rectifiers designed specifically for robust performance in industrial power electronics.
Scrs Replacement Considerations
Check for equivalent parts within the same Vishay series or other manufacturers offering similar SCR specifications. Verify compatibility regarding package dimensions, pinout configuration, and electrical ratings before substitution.
Scrs FAQ
What is the maximum non-repetitive surge current for the VS-25TTS12PBF?
The maximum non-repetitive surge current is 300 A for a 10 ms sine pulse with rated VRRM applied, and 350 A with no voltage reapplied.
Does the VS-25TTS12PBF meet halogen-free requirements?
No, the PbF version is not explicitly stated as halogen-free. Halogen-free compliance is associated with the -M3 suffix variant.
What is the typical turn-off time for this thyristor?
The typical turn-off time (tq) is 110 µs at a junction temperature of 25 °C.
