Substitute Part Grouping Explanation

Substitute parts for the SDB155-TP are classified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Diode Type: Single Phase
Voltage - Peak Reverse (Max): 600 V
Current - Average Rectified (Io): 1.5 A (or lower current rating with equivalent voltage handling)
Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1.5 A (or equivalent)
Mounting Type: Surface Mount
Package / Case: 4-SMD, Gull Wing
Operating Temperature Range: Compatible with -55°C ~ 150°C minimum

Parts are grouped into two categories:

Full Electrical Equivalents (1.5A rated): Parts matching all electrical specifications including 1.5A current rating, 600V voltage rating, and forward voltage characteristics.

Parametric Equivalents with Reduced Current Rating: Parts rated for lower average rectified current (1.0A) but maintaining 600V voltage rating and compatible forward voltage characteristics. These parts are suitable for applications with lower current demands.

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and are suitable for direct replacement in applications designed for the SDB155-TP. Selection among equivalents should be based on the following criteria:

Full Electrical Equivalents (Recommended for Direct Substitution): DF1506S-T, DB155S, DBLS155G, DBLS155GH, DF1506S-E3/77, and DFL1506S-E3/77 all match the 1.5A current rating and 600V voltage specification of the SDB155-TP. These parts are interchangeable from an electrical standpoint.

RoHS Compliance Consideration: All substitute parts listed are RoHS3 compliant except DF06S, which has unspecified RoHS status. For applications requiring RoHS3 compliance certification, select from parts explicitly marked as ROHS3 Compliant.

REACH Status Consideration: DB155S is marked as REACH Affected. All other substitute parts are REACH Unaffected. For applications with REACH compliance requirements, select from REACH Unaffected parts.

Automotive Grade Option: DBLS155GH is qualified to AEC-Q101 automotive standard and carries automotive grade designation. This part is suitable for automotive applications requiring automotive-qualified components.

Reduced Current Rating Option: DF06S is rated for 1.0A average rectified current instead of 1.5A. This part is suitable only for applications with maximum current requirements not exceeding 1.0A.

Temperature Range Consideration: DF1506S-T and DF06S offer extended lower temperature operation to -65°C compared to the standard -55°C of the SDB155-TP. Select these parts for applications requiring operation below -55°C.

Frequently Asked Questions (FAQ)

Q: Can DF06S be used as a direct replacement for SDB155-TP?

A: DF06S is a parametric equivalent with reduced current rating. It is suitable for replacement only in applications where the maximum average rectified current does not exceed 1.0A. For applications requiring the full 1.5A rating, use parts rated for 1.5A current.

Q: What is the difference between DBLS155G and DBLS155GH?

A: Both parts are electrically identical with matching 600V voltage rating, 1.5A current rating, and -55°C to 150°C operating temperature. DBLS155GH carries automotive grade designation and AEC-Q101 qualification, making it suitable for automotive applications. DBLS155G is the standard industrial version.

Q: Are all substitute parts in the same package?

A: All substitute parts use 4-SMD, Gull Wing surface mount package compatible with the SDB155-TP. Packaging format (Tape & Reel or Cut Tape) may differ but does not affect electrical or mechanical compatibility on the PCB.

Q: Which substitute part has the lowest reverse leakage current?

A: DBLS155G and DBLS155GH both specify 2 µA reverse leakage current at 600V, which is lower than the SDB155-TP specification of 10 µA. DB155S and DFL1506S-E3/77 specify 5 µA reverse leakage current.

Q: Can I use DF1506S-T in place of SDB155-TP for low-temperature applications?

A: DF1506S-T is rated for operation down to -65°C compared to SDB155-TP at -55°C. It is suitable for replacement in applications requiring extended low-temperature operation while maintaining full 1.5A current rating and 600V voltage specification.

Q: What compliance certifications should I verify for my application?

A: Verify RoHS3 compliance status and REACH status based on your application requirements. For automotive applications, confirm AEC-Q101 qualification. All listed parts except DF06S are explicitly RoHS3 compliant. DB155S is REACH Affected; all others are REACH Unaffected.
