SL22-M3/5BT Equivalent & Substitute Parts

Part Overview

The SL22-M3/5BT is a Schottky rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 20 V DC reverse voltage and 2 A average rectified current in a surface mount DO-214AA (SMB) package. This component is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package form factor, enabling direct functional replacement in circuit applications where packaging format permits.

Substitute Part Grouping Explanation

Substitute parts for the SL22-M3/5BT are identified based on strict electrical and mechanical parameter equivalence. The following criteria determine substitution eligibility:

Electrical Parameters (Must Match):

Voltage - DC Reverse (Vr) (Max): 20 V
Current - Average Rectified (Io): 2 A
Voltage - Forward (Vf) (Max) @ If: 500 mV @ 2 A
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Current - Reverse Leakage @ Vr: 400 µA @ 20 V
Technology: Schottky

Mechanical Parameters (Must Match):

Package / Case: DO-214AA, SMB
Mounting Type: Surface Mount
Operating Temperature - Junction: -65°C to 125°C

Compliance Parameters (Must Match):

RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level (MSL): 1 (Unlimited)

Packaging format (Tape & Reel, Cut Tape, or Digi-Reel) does not affect electrical or mechanical substitution eligibility; however, procurement and assembly processes may require format-specific consideration.

Engineering Selection Recommendations

All identified substitute parts—SS22-E3/52T and SS22-E3/5BT—maintain complete electrical and mechanical equivalence to the SL22-M3/5BT. All three components are manufactured by Vishay General Semiconductor - Diodes Division, carry Active product status, and meet ROHS3 compliance and MSL 1 (Unlimited) requirements.

The primary distinction between the main part and substitutes is packaging format. The SL22-M3/5BT is supplied in Tape & Reel (TR) format, while SS22-E3/52T is supplied in Cut Tape (CT) format, and SS22-E3/5BT is supplied in Cut Tape (CT) & Digi-Reel® format. Selection between these parts depends on procurement requirements, assembly equipment compatibility, and inventory management practices rather than functional performance.

All three parts are suitable for direct substitution in circuit designs where the DO-214AA (SMB) surface mount package is specified and 20 V / 2 A Schottky rectifier performance is required.

Frequently Asked Questions (FAQ)

Q: Can SS22-E3/52T and SS22-E3/5BT be used interchangeably with SL22-M3/5BT in the same circuit?

A: Yes. All three parts are electrically and mechanically equivalent. They share identical specifications for reverse voltage (20 V), rectified current (2 A), forward voltage drop (500 mV @ 2 A), recovery speed (Fast Recovery ≤ 500ns), reverse leakage current (400 µA @ 20 V), and operating temperature range (-65°C to 125°C). All are housed in the DO-214AA (SMB) surface mount package.

Q: What is the difference between the packaging formats listed?

A: SL22-M3/5BT is supplied in Tape & Reel (TR) format, SS22-E3/52T in Cut Tape (CT) format, and SS22-E3/5BT in Cut Tape (CT) & Digi-Reel® format. These differences affect how components are packaged and handled during procurement and assembly but do not alter electrical performance or mechanical fit.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. SL22-M3/5BT, SS22-E3/52T, and SS22-E3/5BT are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

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

A: Yes. All three parts operate across the same junction temperature range of -65°C to 125°C.

Q: Can packaging format affect circuit performance?

A: No. Packaging format (Tape & Reel, Cut Tape, or Digi-Reel) does not affect electrical characteristics or circuit performance. Format selection is determined by procurement, storage, and assembly process requirements.

Q: Are there any restrictions on using these parts in specific applications?

A: No restrictions are specified in the provided parameters. All parts are rated for identical electrical and thermal conditions and are suitable for any application requiring a 20 V / 2 A Schottky rectifier in DO-214AA (SMB) surface mount form factor.
