Diode Arrays Procurement Notes

Verify the specific part number suffix against official documentation to confirm compliance status. The PbF designation indicates lead-free and RoHS compliance. Confirm that the package outline matches the required TO-220AB dimensions and mounting specifications before integration into the final assembly.

Diode Arrays Selection Notes

Select this component when applications require a center-tap configuration with a 45 V reverse voltage rating. Ensure the thermal management system can maintain the junction temperature within the specified -55 to 150 °C range under the expected load conditions and duty cycles.

Diode Arrays Part Context

This device belongs to the VS-25CTQ...PbF series of high-power Schottky rectifiers. The series includes variants with different voltage ratings, such as 35 V and 40 V options, all sharing the same 15 A per leg current rating and TO-220AB package form factor.

Diode Arrays Replacement Considerations

Compatible substitutes within the same series include the VS-25CTQ035PBF (35 V rating) and the VS-25CTQ040PBF (40 V rating). These parts share identical current ratings and package dimensions but differ in their maximum reverse voltage capabilities.

Diode Arrays FAQ

What is the maximum non-repetitive surge current rating?

The maximum peak one-cycle non-repetitive surge current is 990 A for a 5 μs sine pulse or 250 A for a 10 ms sine pulse.

Does the PbF suffix indicate halogen-free compliance?

No, the PbF suffix indicates lead-free and RoHS compliance. Halogen-free compliance is indicated by the -N3 suffix.

What is the typical series inductance per leg?

The typical series inductance per leg is 8.0 nH, measured lead-to-lead 5 mm from the package body.
