Engineering Selection Recommendations

All three parts—SR1010-TP, MBR1100RLG, and SB1100-T—meet the core electrical requirements for 100V, 1A Schottky rectifier diode applications. Selection between these parts is determined by specific design constraints and availability factors:

SR1010-TP (Micro Commercial Co): Primary specification with 1450 units in stock. Supplied in DO-41 package format. Operating temperature range -55°C to 125°C. RoHS3 compliant and REACH unaffected. Forward voltage 850mV @ 1A.

MBR1100RLG (onsemi): Extended operating temperature range -65°C to 175°C provides thermal margin for high-temperature applications. Supplied in Axial package format with 57700 units in stock. Forward voltage 790mV @ 1A represents lower conduction loss. RoHS3 compliant and REACH unaffected. Moisture sensitivity not applicable.

SB1100-T (Diodes Incorporated): Operating temperature range -65°C to 125°C. Supplied in DO-41 package format with 11461 units in stock. Forward voltage 800mV @ 1A. RoHS3 compliant and REACH unaffected. Moisture sensitivity level 1 (unlimited).

All parts are Active product status and meet compliance requirements. Selection is based on package preference (DO-41 versus Axial), thermal operating range requirements, forward voltage characteristics, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can MBR1100RLG substitute for SR1010-TP in all applications?

A: MBR1100RLG meets all electrical parameters and compliance requirements. The primary difference is package format: MBR1100RLG is supplied as Axial while SR1010-TP is supplied as DO-41. Both are compatible with DO-204AL, DO-41, and Axial package specifications. Verify PCB layout accommodates the Axial package format.

Q: What is the significance of the forward voltage difference between these parts?

A: Forward voltage values are 850mV (SR1010-TP), 790mV (MBR1100RLG), and 800mV (SB1100-T), all measured at 1A. These variations are within normal Schottky diode manufacturing tolerances. Lower forward voltage reduces power dissipation in high-current applications. Circuit design must accommodate the specified maximum forward voltage for each part.

Q: Are there temperature range limitations for substitution?

A: SR1010-TP operates -55°C to 125°C. MBR1100RLG extends to -65°C to 175°C, and SB1100-T to -65°C to 125°C. If the application requires operation below -55°C or above 125°C, MBR1100RLG is the only qualified substitute. Otherwise, all three parts are compatible within the SR1010-TP temperature specification.

Q: What does "Supplier Device Package" mean in relation to substitution?

A: Supplier Device Package indicates the physical format provided by the manufacturer. SR1010-TP and SB1100-T are supplied as DO-41 (single axial leads). MBR1100RLG is supplied as Axial format. All three are compatible with the DO-204AL, DO-41, and Axial package family. Verify the specific lead configuration matches PCB footprint requirements.

Q: Are all three parts RoHS3 compliant?

A: Yes. SR1010-TP, MBR1100RLG, and SB1100-T are all RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: SR1010-TP is supplied in Tape & Reel (TR) format for automated assembly. MBR1100RLG and SB1100-T are supplied in Cut Tape (CT) format. Both formats contain the same electrical component; packaging format affects handling and assembly process compatibility. Verify assembly equipment compatibility with the selected packaging format.

Q: Can these parts be used interchangeably in existing designs?

A: Electrical substitution is valid when all parameters meet or exceed design requirements. Mechanical substitution requires verification that the supplied package format (DO-41 or Axial) matches the PCB footprint. Forward voltage and reverse leakage specifications must be within circuit design tolerances. Consult circuit design documentation to confirm compatibility.
