DF01S Bridge Rectifier Single Phase 100V 1.5A Equivalent & Substitute Parts

Part Overview

The DF01S is a single-phase bridge rectifier diode manufactured by onsemi, rated for 100 V peak reverse voltage and 1.5 A average rectified current in a 4-SDIP surface mount package. The part is classified as "Not For New Designs," indicating it is in mature or declining production status. Alternative equivalent parts are necessary for applications requiring active product support, improved availability, or compliance with current manufacturing standards.

Substitute Part Grouping Explanation

Substitution of the DF01S is determined by the following electrical and mechanical parameters:

Primary Substitution Criteria:

Diode Type: Single Phase (required match)
Package / Case: 4-SMD, Gull Wing (required match for PCB compatibility)
Mounting Type: Surface Mount (required match)
Voltage - Peak Reverse (Max): 100 V (minimum acceptable rating)
Current - Average Rectified (Io): 1.5 A (minimum acceptable rating)

Secondary Considerations:

Operating Temperature Range: -55°C to 150°C or wider
RoHS Compliance Status
Product Status (Active preferred over Not For New Designs or Obsolete)
Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts are grouped into two categories:

Category A - Direct Electrical & Mechanical Equivalents (100 V, 1.5 A, 4-SDIP): Parts with identical voltage and current ratings, same package, and active or compliant status.

Category B - Higher Voltage Rated Alternatives (≥100 V, ≥1.5 A, 4-SMD Gull Wing): Parts with equal or higher voltage ratings and equal or higher current ratings, maintaining package compatibility. These provide enhanced margin for overvoltage conditions.

Engineering Selection Recommendations

Recommended Direct Equivalents (100 V, 1.5 A Rating):

DF1501S and DF1501S-T (Diodes Incorporated) are the primary recommended substitutes for DF01S. Both parts maintain the exact electrical specifications (100 V, 1.5 A) and package compatibility (4-SMD, Gull Wing). Both are classified as Active products with ROHS3 compliance and extended operating temperature range (-65°C to 150°C versus -55°C to 150°C). DF1501S-T is supplied in Tape & Reel packaging with higher inventory availability (16,281 pcs), while DF1501S is supplied in Tube packaging (2,900 pcs).

Alternative with Reduced Current Rating:

DF01S-T (Diodes Incorporated) provides 100 V voltage rating with Active product status and ROHS3 compliance. However, the average rectified current is rated at 1 A instead of 1.5 A. This part is suitable only for applications where the actual circuit current requirement does not exceed 1 A.

Higher Voltage Alternatives for Overvoltage Margin:

DF08S (onsemi, 800 V, 1.5 A) and DF10S (Good-Ark Semiconductor, 1000 V, 1 A) provide significantly higher voltage ratings while maintaining or exceeding current requirements. DF08S maintains the 1.5 A current rating but is classified as Not For New Designs. DF10S is Active but rated for 1 A maximum current. These parts are suitable for applications requiring enhanced voltage margin or operating in high-transient environments.

Parts Not Recommended:

DF005S (50 V rating) is unsuitable as it falls below the 100 V minimum requirement. DF04S (Vishay) is Obsolete and RoHS non-compliant. SDB103-TP (200 V, 1 A) provides reduced current capacity and is Not For New Designs.

Frequently Asked Questions (FAQ)

Q: Can DF01S-T replace DF01S directly?

A: DF01S-T is electrically compatible at the 100 V voltage rating and maintains the same package (4-SMD, Gull Wing). However, the average rectified current is rated at 1 A versus 1.5 A on the original DF01S. Direct replacement is possible only if the circuit current requirement does not exceed 1 A. For applications requiring the full 1.5 A capacity, DF1501S or DF1501S-T are required.

Q: What is the difference between DF1501S and DF1501S-T?

A: Both parts are electrically identical with 100 V, 1.5 A ratings and identical package specifications. The difference is packaging format: DF1501S is supplied in Tube packaging, while DF1501S-T is supplied in Tape & Reel (TR) format. DF1501S-T has significantly higher inventory availability (16,281 pcs versus 2,900 pcs) and is typically preferred for production environments.

Q: Can I use DF08S or DF10S as substitutes?

A: DF08S (800 V, 1.5 A) and DF10S (1000 V, 1 A) are mechanically compatible (4-SMD, Gull Wing package) and provide higher voltage ratings. DF08S maintains the 1.5 A current capacity. These parts are suitable for applications where higher voltage margin is required or beneficial. However, both are classified as Not For New Designs (DF08S) or have reduced current rating (DF10S at 1 A). Use only if the higher voltage rating is a design requirement.

Q: Are all substitute parts RoHS compliant?

A: Most recommended substitutes (DF1501S, DF1501S-T, DF01S-T, DF08S, DF10S) are ROHS3 compliant. DF04S is RoHS non-compliant and not recommended. DF06S compliance status is not specified in the provided data.

Q: What is the operating temperature difference between DF01S and DF1501S?

A: DF01S operates from -55°C to 150°C (TJ). DF1501S and DF1501S-T operate from -65°C to 150°C (TJ), providing 10°C additional margin at the lower temperature extreme. This extended range may be beneficial for applications in cold environments or with stringent thermal specifications.

Q: Can I use DF005S as a substitute?

A: No. DF005S is rated for 50 V peak reverse voltage, which is below the 100 V requirement of DF01S. Using an undersized voltage rating creates risk of diode failure under normal operating conditions and is not acceptable for direct substitution.
