EDF1DS/45 Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The EDF1DS/45 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division, rated for 200 V peak reverse voltage and 1 A average rectified current. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. The part is housed in a 4-SMD, Gull Wing surface mount package (DFS) and operates across the temperature range of -55°C to 150°C.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the EDF1DS/45 are identified based on electrical and mechanical compatibility within the following criteria:

Critical Parameters for Substitution:

• Voltage - Peak Reverse (Max): 200 V minimum
• Diode Type: Single Phase
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing (DFS)
• Operating Temperature Range: -55°C to 150°C minimum

Allowable Parameter Variations:

• Current - Average Rectified (Io): Equal to or greater than 1 A
• Voltage - Forward (Vf): Equal to or less than 1.05 V @ rated current
• Current - Reverse Leakage: Equal to or less than 5 µA @ 200 V

Two substitute parts meet these criteria: EDF1DS-E3/45 (direct equivalent from the same manufacturer) and DF1502S-G (functionally equivalent from Comchip Technology with enhanced current rating).

Parameter Comparison

Engineering Selection Recommendations

EDF1DS-E3/45 is the primary substitute for the obsolete EDF1DS/45. This part is manufactured by the same supplier (Vishay General Semiconductor - Diodes Division) and maintains identical electrical specifications and packaging. The EDF1DS-E3/45 carries Active product status with significantly higher inventory availability (5871 pcs vs. 1104 pcs), ensuring procurement reliability. Both parts are ROHS3 compliant and REACH unaffected, with matching MSL ratings.

DF1502S-G (Comchip Technology) serves as an alternative substitute with enhanced current capacity (1.5 A vs. 1 A). This part meets all critical substitution criteria: identical voltage rating, temperature range, mounting type, and package configuration. The forward voltage specification (1.1 V @ 1.5 A) and reverse leakage current (10 µA @ 200 V) remain within acceptable operational limits for applications designed for the EDF1DS/45. DF1502S-G is also ROHS3 compliant and REACH unaffected. Selection of this part is appropriate for designs requiring additional current margin or where Comchip Technology components are preferred within the supply chain.

Frequently Asked Questions (FAQ)

Q: Can EDF1DS-E3/45 be used as a direct replacement for EDF1DS/45?

A: Yes. EDF1DS-E3/45 is electrically and mechanically identical to EDF1DS/45. Both parts share the same voltage rating (200 V), current rating (1 A), forward voltage specification (1.05 V @ 1 A), reverse leakage (5 µA @ 200 V), temperature range (-55°C to 150°C), and 4-SMD Gull Wing package configuration. The primary difference is product status: EDF1DS-E3/45 is Active with higher inventory availability.

Q: What are the differences between EDF1DS-E3/45 and DF1502S-G?

A: Both parts share identical voltage ratings (200 V), temperature ranges (-55°C to 150°C), and package configurations (4-SMD, Gull Wing, DFS). DF1502S-G has a higher average rectified current rating (1.5 A vs. 1 A), slightly higher forward voltage (1.1 V @ 1.5 A vs. 1.05 V @ 1 A), and higher reverse leakage current (10 µA @ 200 V vs. 5 µA @ 200 V). DF1502S-G is manufactured by Comchip Technology rather than Vishay.

Q: Are all substitute parts in the same package?

A: Yes. EDF1DS/45, EDF1DS-E3/45, and DF1502S-G all use the 4-SMD, Gull Wing package (DFS supplier device package). No PCB layout modifications are required when substituting between these parts.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL rating of 1 (Unlimited). Compliance certifications are identical across EDF1DS/45, EDF1DS-E3/45, and DF1502S-G.

Q: Can DF1502S-G be used in applications originally designed for 1 A operation?

A: Yes. DF1502S-G is rated for 1.5 A average rectified current, which exceeds the 1 A requirement of the original EDF1DS/45 design. The part operates within the same voltage and temperature specifications, making it suitable for applications designed for the lower current rating.
