Diode Arrays Procurement Notes

Verify that the ordering suffix 'TRRPBF' corresponds to the specific tape and reel orientation required by your pick-and-place equipment. Confirm the component meets RoHS directives and material categorization standards before finalizing procurement. Ensure thermal management solutions align with the specified junction-to-case thermal resistance values.

Diode Arrays Selection Notes

Select this component when designing circuits requiring dual Schottky diodes in a single surface-mount footprint. The common cathode topology simplifies layout for bridge or center-tap configurations. Evaluate thermal dissipation requirements based on the 30 A average current rating and ensure adequate heatsinking to maintain junction temperatures below the 150 °C limit during continuous operation.

Diode Arrays Part Context

This part belongs to the VS-25CTQ series of high-power Schottky rectifiers designed for demanding power-conversion environments. The series offers various voltage ratings and packaging options, including tube and reel formats. The D2PAK variant provides robust thermal performance suitable for industrial and automotive electronics where space constraints and heat dissipation are critical design factors.

Diode Arrays Replacement Considerations

Compatible substitutes within the same family include VS-25CTQ035SPbF and VS-25CTQ045SPbF, which share identical pinouts and thermal characteristics but differ in reverse voltage ratings. Verify that any replacement maintains the AEC-Q101 qualification if used in automotive applications.

Diode Arrays FAQ

What is the maximum non-repetitive surge current rating?

The device can withstand a peak one-cycle non-repetitive surge current of 990 A for a 5 μs sine pulse or 250 A for a 10 ms sine pulse per leg.

How does the forward voltage drop vary with temperature?

The forward voltage drop decreases as junction temperature increases; it is rated at 0.56 V at 25 °C and drops to 0.50 V at 125 °C for a 15 A forward current.

Is the component suitable for high-frequency applications?

Yes, the Schottky barrier technology and low junction capacitance (typically 900 pF) support high-frequency operation typical in modern switching power supplies.
