SS22-M3/5BT Equivalent & Substitute Parts

Part Overview

The SS22-M3/5BT is a Schottky rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 20V DC reverse voltage and 2A average rectified current in a surface mount DO-214AA (SMB) package. This component is classified as Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameters. Alternative sources become necessary due to supply chain considerations, product lifecycle status, or inventory availability while maintaining identical functional specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SS22-M3/5BT are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

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

Mechanical Compatibility Criteria:

• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Operating Temperature Range: Must encompass or exceed -60°C to 125°C

Compliance Requirements:

• RoHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting all electrical and mechanical criteria are classified as direct substitutes. Variations in reverse leakage current or capacitance do not disqualify substitution when primary electrical parameters are maintained.

Parameter Comparison

Engineering Selection Recommendations

SS22T3G (onsemi): This substitute part maintains electrical equivalence across all critical parameters and extends the operating temperature range to -55°C ~ 150°C. The part carries Last Time Buy status, indicating limited future availability. Selection of this part is appropriate for applications requiring extended temperature performance, provided supply chain continuity is confirmed with the manufacturer.

B220-13-F (Diodes Incorporated): This substitute part maintains electrical equivalence and offers the widest operating temperature range (-65°C ~ 150°C) among the three options. Active product status ensures ongoing availability and supply chain stability. This part is suitable for applications requiring extended temperature performance and long-term component availability. Reverse leakage current is specified at 500 µA @ 20V, which remains within acceptable limits for Schottky rectifier applications.

Both substitute parts are RoHS3 compliant with MSL 1 rating, matching the original part's compliance profile. Selection between substitutes should be based on supply chain requirements, temperature operating range needs, and long-term product lifecycle considerations.

Frequently Asked Questions (FAQ)

Q: Can SS22T3G be used as a direct replacement for SS22-M3/5BT?

A: Yes. Both parts share identical electrical specifications for voltage rating (20V), current rating (2A), forward voltage drop (500mV @ 2A), and switching speed (Fast Recovery ≤ 500ns). Both use the DO-214AA (SMB) surface mount package. The SS22T3G extends the upper operating temperature limit to 150°C compared to 125°C for the original part.

Q: What is the difference between SS22T3G and B220-13-F?

A: Both parts meet the electrical requirements of the SS22-M3/5BT. The primary differences are: (1) SS22T3G carries Last Time Buy status while B220-13-F is Active; (2) B220-13-F extends the lower operating temperature to -65°C versus -55°C for SS22T3G; (3) B220-13-F specifies reverse leakage at 500 µA @ 20V versus 400 µA @ 40V for SS22T3G. Both are RoHS3 compliant with MSL 1 rating.

Q: Are there package compatibility concerns when substituting these parts?

A: No. All three parts use the DO-214AA (SMB) surface mount package with identical mechanical dimensions and land pattern requirements. PCB layout and assembly processes require no modification.

Q: Does reverse leakage current variation affect substitution suitability?

A: Reverse leakage current specifications differ slightly among the three parts (400 µA @ 20V for SS22-M3/5BT, 400 µA @ 40V for SS22T3G, and 500 µA @ 20V for B220-13-F). These variations remain within acceptable limits for Schottky rectifier applications and do not disqualify substitution when primary electrical parameters are maintained.

Q: Which substitute part should be selected for new designs?

A: B220-13-F is recommended for new designs due to Active product status, ensuring long-term availability and supply chain stability. The extended operating temperature range (-65°C ~ 150°C) provides additional design margin for temperature-sensitive applications.

Q: Are all three parts RoHS3 compliant?

A: Yes. SS22-M3/5BT, SS22T3G, and B220-13-F are all RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, meeting identical environmental and regulatory requirements.
