DF005S Bridge Rectifier Single Phase 50V 1.5A Equivalent & Substitute Parts

Part Overview

The DF005S is a single-phase bridge rectifier diode manufactured by onsemi, rated for 50 V peak reverse voltage and 1.5 A average rectified current in a 4-SDIP surface mount package. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. For applications requiring continued supply or new designs, equivalent and substitute parts with matching or higher electrical ratings are available from multiple manufacturers.

Substitute Part Grouping Explanation

Substitution of the DF005S is determined by the following criteria:

Electrical Compatibility: Peak reverse voltage must equal or exceed 50 V; average rectified current must equal or exceed 1.5 A; forward voltage drop and reverse leakage characteristics must remain within acceptable operating margins.

Mechanical Compatibility: Package type must be 4-SMD, Gull Wing to ensure PCB footprint compatibility; mounting type must be surface mount.

Regulatory Compliance: RoHS3 compliance is required for new designs in regulated markets; REACH status should be evaluated based on application requirements.

Substitute parts are grouped into two categories:

Direct Electrical Equivalents (50 V Rating): Parts with identical 50 V peak reverse voltage and 1.5 A current rating, differing only in manufacturer, packaging format, or product status.

Higher Voltage Alternatives (100 V and Above): Parts with elevated voltage ratings that function in 50 V applications with improved safety margin but may introduce different thermal or leakage characteristics.

Engineering Selection Recommendations

For Direct Replacement (50 V Applications):

DB151S (SMC Diode Solutions) and DF15005S or DF15005S-T (Diodes Incorporated) are active product alternatives with identical 50 V / 1.5 A ratings and ROHS3 compliance. DB151S maintains the original -55°C to 150°C temperature range. DF15005S and DF15005S-T extend the lower operating temperature to -65°C and are available in both bulk and tape & reel packaging formats.

DF005S-T (Diodes Incorporated) is an active alternative with reduced current rating (1 A versus 1.5 A) and extended temperature range (-65°C to 150°C). This part is suitable only for applications with maximum current requirements not exceeding 1 A.

For Higher Voltage Margin Applications:

DF01S (onsemi, 100 V rating) provides a 2× voltage safety margin while maintaining 1.5 A current capacity and ROHS3 compliance. This part is classified as "Not For New Designs."

DF08S (onsemi, 800 V rating) and DF10S (Good-Ark Semiconductor, 1 kV rating) are available for applications requiring significantly elevated voltage ratings. DF10S is active and ROHS3 compliant; DF08S is classified as "Not For New Designs."

Parts to Avoid:

DF04S (Vishay) is obsolete and RoHS non-compliant and should not be selected for new designs.

DF06S (Fairchild Semiconductor) lacks specified RoHS status and should be evaluated for regulatory compliance before selection.

Frequently Asked Questions (FAQ)

Q: Can DF005S-T replace DF005S directly?

A: DF005S-T is electrically compatible at the 50 V / 1 A rating level. However, the original DF005S is rated for 1.5 A average rectified current. DF005S-T is suitable only for applications where maximum current does not exceed 1 A. Extended temperature range (-65°C to 150°C) is an additional benefit.

Q: What is the difference between DB151S and DF15005S?

A: Both parts are rated 50 V / 1.5 A with identical forward voltage and reverse leakage characteristics. DB151S is manufactured by SMC Diode Solutions and supplied in tape & reel format. DF15005S is manufactured by Diodes Incorporated and available in bulk or tape & reel (DF15005S-T) formats. Both are active products with ROHS3 compliance.

Q: Can I use DF01S (100 V) in a 50 V application?

A: Yes. DF01S has a higher peak reverse voltage rating (100 V) than required for 50 V applications, providing additional safety margin. Electrical characteristics (forward voltage, reverse leakage, current rating) remain compatible. This part is classified as "Not For New Designs."

Q: Are all substitute parts in 4-SDIP package?

A: All listed substitute parts use 4-SMD, Gull Wing package configuration, ensuring mechanical compatibility with DF005S PCB footprints.

Q: Which substitute part has the best regulatory compliance?

A: DB151S, DF15005S, DF15005S-T, DF005S-T, DF01S, DF08S, and DF10S are all ROHS3 compliant. DF04S is RoHS non-compliant. DF06S does not specify RoHS status.

Q: What is the inventory status of active alternatives?

A: DF15005S-T (8,875 pcs), DF15005S (3,370 pcs), DF005S-T (10,100 pcs), and DB151S (701 pcs) are currently in stock as active products. DF01S (6,258 pcs) and DF08S (35,100 pcs) are in stock but classified as "Not For New Designs."
