Frequently Asked Questions (FAQ)

Q: Can the UPS3100E3/TR13 be used as a direct replacement for the MBRM3100-13 in existing designs?

A: Yes. The UPS3100E3/TR13 meets all critical electrical specifications including voltage rating (100 V), current rating (3 A), forward voltage (760 mV @ 3 A), recovery speed (≤ 500ns), and package type (Powermite®3). No circuit modifications are required.

Q: What are the differences between the MBRM3100-13 and UPS3100E3/TR13?

A: The primary differences are: (1) Reverse leakage current is 200 µA for the UPS3100E3/TR13 versus 100 µA for the MBRM3100-13; (2) Junction capacitance is 85 pF for the UPS3100E3/TR13 versus 100 pF for the MBRM3100-13; (3) The UPS3100E3/TR13 is RoHS3 compliant while the MBRM3100-13 is non-compliant; (4) The UPS3100E3/TR13 is currently in active production.

Q: Are the packages physically identical?

A: Yes. Both components use the Powermite®3 surface mount package with identical mechanical dimensions and pin configuration, enabling direct PCB footprint compatibility.

Q: Does the higher reverse leakage current of the UPS3100E3/TR13 affect circuit performance?

A: The reverse leakage current difference (200 µA versus 100 µA at 100 V) is within normal Schottky diode manufacturing tolerance and does not affect standard rectifier circuit operation. Applications with specific leakage current requirements should evaluate this parameter against design specifications.

Q: Is the lower junction capacitance of the UPS3100E3/TR13 beneficial?

A: Lower junction capacitance (85 pF versus 100 pF) can provide improved high-frequency performance characteristics. This represents a minor improvement for switching applications.

Q: What is the packaging format of the UPS3100E3/TR13?

A: The UPS3100E3/TR13 is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, suitable for both manual and automated assembly processes.
