Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RS3B-13 are qualified based on the following criteria:

Primary Substitution Parameters:

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 3 A
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts maintain these core electrical and mechanical specifications. Variations in secondary parameters such as forward voltage (Vf), reverse recovery time (trr), and reverse leakage current are within acceptable ranges for general-purpose rectification applications. Packaging format differences (Cut Tape versus Tape & Reel) do not affect electrical equivalence but may impact procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

Active Status Parts (Recommended for New Designs): RS3B-13-F, ES3B-E3/9AT, ES3B, ES3B-E3/57T, and S3B maintain Active product status and are suitable for new design implementations. These parts are supported by manufacturers for ongoing production and technical support.

Packaging Format Considerations:

• Cut Tape (CT) format: RS3B-13, ES3B-E3/57T
• Tape & Reel (TR) format: RS3B-13-F, ES3B-E3/9AT, S3B-TP
• Unspecified format: ES3B, S3B

Selection between Cut Tape and Tape & Reel formats depends on assembly process requirements and volume specifications.

Compliance Status: All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.

Obsolescence Consideration: S3B-TP carries "Not For New Designs" status and should be avoided in new product development. This part is suitable only for maintenance or repair of existing systems.

Frequently Asked Questions (FAQ)

Q: Can RS3B-13-F be used as a direct replacement for RS3B-13?

A: Yes. Both parts are manufactured by Diodes Incorporated with identical electrical ratings (100V, 3A) and package specifications (DO-214AB, SMC). The primary difference is packaging format: RS3B-13 is supplied in Cut Tape format while RS3B-13-F is supplied in Tape & Reel format. Electrical performance is equivalent.

Q: What is the difference between fast recovery and standard recovery diodes in this product line?

A: RS3B-13-F and ES3B-E3/9AT feature fast recovery characteristics with reverse recovery times of 150 ns and 30 ns respectively. S3B and S3B-TP feature standard recovery with reverse recovery times exceeding 500 ns. Fast recovery diodes exhibit lower switching losses and are suitable for higher frequency applications, while standard recovery diodes are appropriate for lower frequency rectification.

Q: Are Vishay ES3B-E3/9AT and ES3B-E3/57T electrically identical?

A: Yes. Both Vishay parts share identical electrical specifications: 100V reverse voltage, 3A current rating, 900 mV forward voltage at 3A, and 30 ns reverse recovery time. The distinction is packaging format: ES3B-E3/9AT is supplied in Tape & Reel format while ES3B-E3/57T is supplied in Cut Tape format.

Q: Why do forward voltage specifications vary among substitute parts?

A: Forward voltage variation (ranging from 900 mV to 1.3 V at 3A) reflects differences in semiconductor material quality, junction design, and manufacturing process between manufacturers. All values remain within acceptable ranges for general-purpose rectification. Selection should consider thermal management requirements in the specific application circuit.

Q: Is the Taiwan Semiconductor Corporation ES3B suitable for new designs?

A: Yes. ES3B maintains Active product status and ROHS3 compliance. However, packaging format is not specified in available documentation. Clarification with the supplier regarding packaging availability is recommended before design implementation.

Q: What does "Not For New Designs" mean for the S3B-TP part?

A: This designation indicates that Micro Commercial Co does not recommend this part for new product development. S3B-TP is available for existing system maintenance and repair only. For new designs, select from parts with Active status: RS3B-13-F, ES3B-E3/9AT, ES3B, ES3B-E3/57T, or S3B.

Q: Can I substitute a fast recovery diode for a standard recovery diode in my application?

A: Fast recovery diodes can replace standard recovery diodes in most applications due to superior switching characteristics. However, the reverse is not true. Standard recovery diodes should not replace fast recovery diodes in high-frequency switching applications. Verify application frequency requirements before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts maintain ROHS3 compliance status, ensuring compatibility with environmental regulations and manufacturing standards across all major markets.
