DF1510S Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DF1510S is a single-phase bridge rectifier manufactured by Diodes Incorporated, rated for 1 kV peak reverse voltage and 1.5 A average rectified current. This surface mount component operates across -65°C to 150°C and is designed for general-purpose rectification applications requiring standard bridge rectifier performance. The part is active in production with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when electrical parameters (voltage rating, current capacity, forward voltage, leakage current) and mechanical specifications (package type, mounting method) align with the DF1510S requirements, enabling direct replacement in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF1510S is determined by the following criteria:

Primary Electrical Parameters:

• Voltage - Peak Reverse (Max): 1 kV minimum
• Current - Average Rectified (Io): 1.5 A or greater
• Diode Type: Single Phase
• Technology: Standard

Secondary Electrical Parameters:

• Voltage - Forward (Vf) (Max) @ If: Must not exceed specified operating conditions
• Current - Reverse Leakage @ Vr: Must remain within acceptable limits at rated voltage

Mechanical & Package Requirements:

• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing configuration
• RoHS Status: ROHS3 Compliant

Parts meeting all primary criteria and maintaining compatibility with secondary parameters and package specifications are classified as direct substitutes. Parts with reduced current ratings (1 A vs. 1.5 A) are listed as functional alternatives where application current requirements do not exceed the substitute part's rating.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Identical Electrical & Mechanical Specifications):

DF1510S-T (Diodes Incorporated) and SDB157-TP (Micro Commercial Co) are direct substitutes with matching 1.5 A current ratings, 1 kV voltage ratings, and 4-SMD Gull Wing packaging. Both maintain ROHS3 compliance and active product status. DF1510S-T differs only in packaging format (Cut Tape & Digi-Reel vs. Bulk). SDB157-TP operates across -55°C to 150°C, providing a narrower lower temperature bound compared to the DF1510S (-65°C minimum).

DB157S (MDD) meets all primary electrical specifications with 1.5 A current and 1 kV voltage rating. Forward voltage is reduced to 1 V @ 1.5 A, and reverse leakage is lower at 1 µA @ 1000 V. Operating temperature range is -55°C to 150°C. All parts maintain ROHS3 compliance and active status.

Functional Alternatives (Reduced Current Rating):

DF10S (Good-Ark Semiconductor) and SDB107-TP (Micro Commercial Co) are rated for 1 A average rectified current, compared to the DF1510S 1.5 A rating. Both maintain 1 kV voltage rating and 4-SMD Gull Wing packaging. These parts are suitable for applications where circuit current requirements do not exceed 1 A. Operating temperature range is -55°C to 150°C for both alternatives.

All substitute parts listed are active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can DF1510S-T replace DF1510S directly?

A: Yes. DF1510S-T is electrically and mechanically identical to DF1510S. The difference is packaging format: DF1510S-T is supplied in Cut Tape & Digi-Reel format, while DF1510S is supplied in Bulk. Both are manufactured by Diodes Incorporated with identical electrical specifications and operating temperature range (-65°C to 150°C).

Q: What is the difference between DB157S and DF1510S?

A: DB157S (MDD) matches the DF1510S in voltage (1 kV) and current (1.5 A) ratings and package type (4-SMD Gull Wing). DB157S has lower forward voltage (1 V vs. 1.1 V @ 1.5 A) and lower reverse leakage (1 µA vs. 10 µA @ 1000 V). Operating temperature range is -55°C to 150°C, compared to DF1510S at -65°C to 150°C. DB157S is suitable for applications not requiring operation below -55°C.

Q: Can DF10S or SDB107-TP be used instead of DF1510S?

A: DF10S and SDB107-TP are functional alternatives only when circuit current requirements do not exceed 1 A. Both parts are rated for 1 A average rectified current, compared to DF1510S at 1.5 A. Voltage rating (1 kV) and package type (4-SMD Gull Wing) are identical. These parts are not suitable for applications requiring 1.5 A operation.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (DF1510S-T, DB157S, SDB157-TP, DF10S, SDB107-TP) are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: What is the operating temperature difference between DF1510S and substitute parts?

A: DF1510S operates from -65°C to 150°C. DB157S, SDB157-TP, DF10S, and SDB107-TP operate from -55°C to 150°C. DF1510S-T matches DF1510S at -65°C to 150°C. Applications requiring operation below -55°C must use DF1510S or DF1510S-T.

Q: What packaging formats are available for DF1510S substitutes?

A: DF1510S is supplied in Bulk packaging. DF1510S-T is available in Cut Tape & Digi-Reel format. DB157S packaging format is not specified. SDB157-TP is supplied in Tape & Reel format. DF10S is available in Cut Tape & Digi-Reel and Tape & Reel formats. SDB107-TP is supplied in Cut Tape & Digi-Reel format. All maintain identical 4-SMD Gull Wing package configuration.
