Engineering Selection Recommendations

Direct Substitutes (Electrical and Mechanical Equivalence):

The SMBJ110A-13-F (Diodes Incorporated) and SMBJ110A (MDD) are direct substitutes for the SMBJ110A-13. Both parts maintain identical electrical specifications across all critical parameters: 110V reverse standoff voltage, 122V minimum breakdown voltage, 177V maximum clamping voltage, and 3.4A peak pulse current. All three parts are ROHS3 compliant, active-status products in the SMB package.

The SMBJ110A-13-F differs only in packaging designation (Cut Tape & Digi-Reel) and inventory availability (4700 pcs vs. 18100 pcs for the main part).

The SMBJ110A (MDD) operates across a slightly reduced temperature range (-50 to 150°C versus -55 to 150°C) but maintains all electrical equivalence. This part offers significantly higher inventory availability (47400 pcs).

Similar Part (Functional Equivalence with Parameter Variation):

The SMBJ100CA-TP (Micro Commercial Co) is classified as a similar part. This device operates at a lower reverse standoff voltage (100V versus 110V) with correspondingly lower breakdown (111V) and clamping (162V) voltages. Peak pulse current is slightly higher at 3.7A. The operating temperature range extends to 175°C. This part is suitable for applications requiring lower voltage suppression thresholds and is packaged in Tape & Reel format.

All substitute parts maintain ROHS3 compliance, active product status, and surface-mount SMB package compatibility.

Frequently Asked Questions (FAQ)

Q: Can SMBJ110A-13-F be used as a direct replacement for SMBJ110A-13?

A: Yes. The SMBJ110A-13-F is a direct substitute. Both parts are manufactured by Diodes Incorporated and share identical electrical specifications: 110V reverse standoff, 177V clamping voltage, and 3.4A peak pulse current. The primary difference is packaging format (Cut Tape & Digi-Reel designation). Both are ROHS3 compliant and rated for -55 to 150°C operation.

Q: What is the difference between the SMBJ110A from MDD and the original SMBJ110A-13?

A: The MDD SMBJ110A maintains all critical electrical parameters identical to the SMBJ110A-13: 110V standoff, 177V clamping, and 3.4A peak pulse current. The operating temperature range is slightly reduced (minimum -50°C versus -55°C). This part is a direct electrical substitute suitable for most applications. Verify minimum operating temperature requirements for your specific circuit design.

Q: Is SMBJ100CA-TP compatible with SMBJ110A-13?

A: The SMBJ100CA-TP is a similar part, not a direct substitute. It operates at lower voltage levels: 100V reverse standoff (versus 110V), 162V clamping (versus 177V), and 111V breakdown (versus 122V). Peak pulse current is slightly higher at 3.7A. This part is suitable only for circuits designed for 100V suppression thresholds. Do not use in applications requiring 110V standoff voltage protection.

Q: Are all substitute parts available in the same SMB package?

A: Yes. All listed parts—SMBJ110A-13, SMBJ110A-13-F, SMBJ110A (MDD), and SMBJ100CA-TP—are packaged in DO-214AA (SMB) format and are surface-mount compatible. Packaging variations exist in tape format (Cut Tape & Digi-Reel versus Tape & Reel), but the physical component package remains identical.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. All listed parts are ROHS3 compliant. The main part SMBJ110A-13 and all direct substitutes (SMBJ110A-13-F and SMBJ110A from MDD) carry identical ROHS3 certification. The similar part SMBJ100CA-TP is also ROHS3 compliant.

Q: What inventory levels are available for each part?

A: SMBJ110A-13 (main): 18100 pcs; SMBJ110A-13-F: 4700 pcs; SMBJ110A (MDD): 47400 pcs; SMBJ100CA-TP: 2928 pcs. The MDD SMBJ110A offers the highest inventory availability among direct substitutes.

Q: Can SMBJ110A-13 be used in applications requiring extended temperature operation to 175°C?

A: No. The SMBJ110A-13 is rated to 150°C maximum junction temperature. The SMBJ100CA-TP extends to 175°C, but this part operates at lower voltage levels (100V standoff versus 110V). Select the SMBJ100CA-TP only if your circuit design accommodates the lower voltage suppression threshold and requires the extended temperature range.
