SL23-M3/52T Equivalent & Substitute Parts

Part Overview

The SL23-M3/52T is a Schottky rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 30 V DC reverse voltage and 2 A average rectified current in a surface mount DO-214AA (SMB) package. This component is classified as Active and complies with ROHS3 and REACH standards. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to packaging format availability, inventory constraints, or supply chain considerations.

Substitute Part Grouping Explanation

Substitute parts for the SL23-M3/52T are identified based on electrical parameter equivalence and mechanical compatibility. All substitute parts share identical electrical specifications: 30 V reverse voltage rating, 2 A average rectified current, 440 mV forward voltage drop at 2 A, fast recovery speed characteristics, and 400 µA reverse leakage current at 30 V. All substitute parts utilize the same DO-214AA (SMB) surface mount package and operate across the identical temperature range of -55°C to 125°C.

The primary distinction between the main part and substitutes is the packaging format: the SL23-M3/52T is supplied in Tape & Reel (TR) format, while substitute parts are available in Cut Tape (CT) or alternative Tape & Reel configurations. All parts are manufactured by Vishay General Semiconductor - Diodes Division, share the same base product number (SL23), maintain Active product status, and comply with ROHS3, REACH, and MSL 1 requirements.

Engineering Selection Recommendations

All three parts—SL23-M3/52T, SL23-E3/52T, and SL23-E3/5BT—are electrically and mechanically equivalent for applications requiring a 30 V, 2 A Schottky rectifier diode in DO-214AA surface mount package. Selection between these parts is determined by packaging format requirements and inventory availability.

The SL23-M3/52T and SL23-E3/5BT are both supplied in Tape & Reel (TR) format, suitable for automated assembly processes requiring continuous reel feeding. The SL23-E3/52T is supplied in Cut Tape (CT) format, appropriate for manual assembly or lower-volume production runs.

All parts maintain Active product status, comply with ROHS3 and REACH regulations, and carry MSL 1 (Unlimited) moisture sensitivity classification. No thermal, electrical, or environmental performance differences exist between these parts. Component selection should be based solely on packaging format compatibility with the intended assembly process and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can SL23-E3/52T (Cut Tape) be used as a direct replacement for SL23-M3/52T (Tape & Reel)?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. Cut Tape format is suitable for manual assembly or lower-volume applications, while Tape & Reel format is optimized for automated high-volume production. The component itself performs identically in the circuit.

Q: Are there electrical performance differences between SL23-M3/52T and SL23-E3/5BT?

A: No. Both parts share identical electrical specifications: 30 V reverse voltage, 2 A average rectified current, 440 mV forward voltage drop at 2 A, fast recovery characteristics, and 400 µA reverse leakage current. Both are supplied in Tape & Reel format.

Q: What is the primary distinction between these substitute parts?

A: The SL23-E3/52T differs only in packaging format (Cut Tape instead of Tape & Reel). The SL23-E3/5BT differs only in the specific reel configuration designation. All electrical and thermal characteristics remain identical across all three part numbers.

Q: Do all three parts comply with the same regulatory standards?

A: Yes. All three parts are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity classification. No regulatory or compliance differences exist between them.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the assembly process accommodates the packaging format. Tape & Reel parts (SL23-M3/52T and SL23-E3/5BT) are compatible with automated pick-and-place equipment. Cut Tape parts (SL23-E3/52T) are suitable for manual placement or semi-automated processes. Once soldered, the components perform identically.

Q: What is the operating temperature range for all substitute parts?

A: All parts operate across a junction temperature range of -55°C to 125°C. No thermal performance differences exist between the three part numbers.
