SL43-M3/9AT Equivalent & Substitute Parts

Part Overview

The SL43-M3/9AT is a Schottky rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 30 V DC reverse voltage and 4 A average rectified current. The device is packaged in DO-214AB (SMC) surface mount configuration and supplied in Tape & Reel (TR) format. This component is classified as Active product status and is RoHS3 compliant with REACH Unaffected designation.

Equivalent and substitute parts are identified based on matching electrical performance characteristics and mechanical compatibility within the Schottky diode rectifier category. Substitution becomes necessary when the primary part number is unavailable, when alternative packaging formats are required for manufacturing processes, or when supply chain optimization is needed while maintaining identical electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SL43-M3/9AT is determined by equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io): 4 A
• Voltage - Forward (Vf) (Max) @ If: 420 mV @ 4 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 500 µA @ 30 V

Mechanical Equivalence Criteria:

• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 125°C

Compliance Equivalence Criteria:

• Technology: Schottky
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

All substitute parts listed maintain identical electrical performance and mechanical compatibility. Differences exist only in packaging format (Tape & Reel versus Cut Tape) and inventory availability. The base product number SL43 is common across all equivalent devices.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are functionally equivalent to the SL43-M3/9AT and are suitable for direct substitution in applications requiring a 30 V, 4 A Schottky rectifier diode in DO-214AB surface mount package.

Selection Basis:

All substitute parts maintain Active product status with ROHS3 compliance and REACH Unaffected designation, ensuring regulatory alignment with the primary part number. Electrical specifications are identical across all variants, including reverse voltage rating, average rectified current, forward voltage drop, recovery speed, and reverse leakage current characteristics.

Packaging Format Considerations:

The primary distinction among equivalent parts is packaging format. The SL43-M3/9AT is supplied in Tape & Reel (TR) format. The SL43-E3/57T is supplied in Cut Tape (CT) format, while SL43-E3/9AT and SL43-M3/57T are supplied in Tape & Reel (TR) format. Selection between these formats depends on manufacturing process requirements and assembly equipment compatibility.

Inventory Availability:

Current inventory levels vary across equivalent part numbers. Selection may be optimized based on supply chain requirements and lead time considerations while maintaining identical electrical and mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can SL43-E3/57T be used as a direct replacement for SL43-M3/9AT?

A: Yes. The SL43-E3/57T is electrically and mechanically equivalent to the SL43-M3/9AT. Both devices are Schottky rectifier diodes with identical 30 V reverse voltage rating, 4 A average rectified current, and DO-214AB surface mount package. The primary difference is packaging format: SL43-E3/57T is supplied in Cut Tape (CT) format while SL43-M3/9AT is supplied in Tape & Reel (TR) format. Compatibility depends on assembly equipment capability to process Cut Tape format.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel (TR) format supplies components on continuous tape wound on a reel, suitable for automated pick-and-place assembly equipment. Cut Tape (CT) format supplies components on tape segments of specified lengths, typically used for manual assembly or lower-volume production. Both formats contain identical components in the same DO-214AB package.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts, including SL43-M3/9AT, SL43-E3/57T, SL43-E3/9AT, and SL43-M3/57T, are ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: Do substitute parts have the same operating temperature range?

A: Yes. All substitute parts operate across the identical junction temperature range of -55°C to 125°C, ensuring thermal performance equivalence across all variants.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All substitute parts have MSL rating of 1 (Unlimited), indicating unlimited shelf life without moisture control requirements during storage and handling.

Q: Can I substitute SL43-M3/9AT with SL43-E3/9AT?

A: Yes. The SL43-E3/9AT is electrically and mechanically equivalent to the SL43-M3/9AT. Both are supplied in Tape & Reel (TR) format with identical electrical specifications and DO-214AB surface mount package. The substitution is direct with no assembly process modifications required.

Q: Are there any electrical performance differences between the substitute parts?

A: No. All substitute parts maintain identical electrical specifications: 30 V maximum reverse voltage, 4 A average rectified current, 420 mV maximum forward voltage at 4 A, fast recovery speed ≤ 500ns, and 500 µA maximum reverse leakage current at 30 V.
