TSSA5U60 Equivalent & Substitute Parts

Part Overview

The TSSA5U60 is a Schottky rectifier diode rated for 60 V DC reverse voltage and 5 A average rectified current in a surface mount DO-214AC (SMA) package. Manufactured by Taiwan Semiconductor Corporation, this component is classified as "Not For New Designs," indicating it has reached end-of-life status. The product remains in inventory with 2300 units available as new original stock.

Due to its discontinued design status, identification of equivalent and substitute parts is necessary for ongoing maintenance, repair, and legacy system support. Substitute components must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating available packaging options.

Substitute Part Grouping Explanation

Substitute parts for the TSSA5U60 are classified into two categories based on electrical parameter alignment:

Direct Parametric Equivalent: The TSSA5U60 M2G maintains identical electrical specifications (60 V, 5 A, 560 mV forward voltage, 300 µA reverse leakage) and package configuration. This part differs only in product status (Active versus Not For New Designs) and represents the direct successor for new applications.

Current-Reduced Substitutes: Parts rated for 1 A, 2 A, or 3 A average rectified current operate within the same 60 V reverse voltage class and fast recovery speed category. These substitutes are applicable in circuits where the full 5 A capacity is not required. Selection depends on actual circuit current demands and thermal dissipation requirements.

Key Parameters Determining Substitution:

Voltage - DC Reverse (Vr) (Max): Must equal or exceed 60 V
Technology: Must be Schottky type
Speed: Must be Fast Recovery ≤ 500ns, > 200mA (Io)
Package / Case: DO-214AC (SMA) or compatible surface mount packages
Operating Temperature Range: Must accommodate -55°C ~ 150°C minimum
RoHS Status: ROHS3 Compliant required

Engineering Selection Recommendations

Primary Recommendation: TSSA5U60 M2G is the direct parametric equivalent with Active product status. This part maintains all electrical specifications of the original TSSA5U60 while offering ongoing availability and support. Selection of this part eliminates any performance variation and is appropriate for all applications currently using TSSA5U60.

Secondary Recommendations for Current-Reduced Applications:

The B360A-E3/5AT and B360A-E3/61T (3 A rated) are suitable for applications requiring 3 A or less. These parts maintain the same 60 V reverse voltage rating, fast recovery speed, and DO-214AC package. Operating temperature range matches the original (-55°C ~ 150°C). Both parts are Active status with ROHS3 compliance.

The B260AQ-13-F (2 A rated) is suitable for applications requiring 2 A or less. This part includes AEC-Q101 automotive qualification and maintains 60 V reverse voltage and DO-214AC package compatibility. Operating temperature extends to -65°C.

The B160 series (1 A rated) including B160-13-F, B160-E3/5AT, and B160-E3/61T are suitable only for applications requiring 1 A or less. These parts maintain 60 V reverse voltage and fast recovery characteristics. B160Q-13-F includes AEC-Q101 automotive qualification.

Package Consideration: B160B-13-F uses DO-214AA (SMB) package instead of DO-214AC (SMA). This part is not recommended for direct substitution in applications requiring SMA package footprint compatibility.

Compliance Status: All recommended substitutes maintain ROHS3 compliance, MSL 1 (Unlimited), and REACH Unaffected status consistent with the original TSSA5U60.

Frequently Asked Questions (FAQ)

Q: Can TSSA5U60 M2G be used as a direct replacement for TSSA5U60?

A: Yes. TSSA5U60 M2G is the direct parametric equivalent with identical electrical specifications (60 V, 5 A, 560 mV forward voltage, 300 µA reverse leakage) and package configuration (DO-214AC SMA). The only difference is product status (Active versus Not For New Designs).

Q: What is the primary reason to substitute TSSA5U60 with another part?

A: TSSA5U60 is classified as "Not For New Designs," indicating discontinued status. While 2300 units remain in inventory, long-term availability is not guaranteed. TSSA5U60 M2G provides equivalent performance with Active product status and ongoing manufacturer support.

Q: Can I use a 1 A rated diode (B160 series) in place of the 5 A TSSA5U60?

A: Only if your circuit requires 1 A or less average rectified current. The B160 series maintains the same 60 V reverse voltage rating and fast recovery speed. However, using a lower-rated part in a circuit designed for 5 A will result in excessive power dissipation and potential thermal failure. Verify actual circuit current requirements before substitution.

Q: What is the difference between B160-E3/5AT and B160-E3/61T?

A: Both parts are electrically identical (60 V, 1 A, 750 mV forward voltage, 200 µA reverse leakage, DO-214AC package). The difference is packaging format: B160-E3/5AT is supplied in Cut Tape (CT) & Digi-Reel format, while B160-E3/61T is supplied in Cut Tape (CT) only. Selection depends on your procurement and assembly requirements.

Q: Why does B160Q-13-F show 500 µA reverse leakage @ 40 V instead of @ 60 V?

A: B160Q-13-F is specified with reverse leakage measured at 40 V rather than 60 V. This represents a different measurement condition but does not affect substitution suitability. The part maintains 60 V maximum reverse voltage rating and is qualified to AEC-Q101 automotive standards.

Q: Can I use B160B-13-F (SMB package) instead of TSSA5U60 (SMA package)?

A: B160B-13-F uses DO-214AA (SMB) package, which has different physical dimensions and PCB footprint than DO-214AC (SMA). Direct substitution is not possible without PCB redesign. Use only if your application can accommodate SMB package footprint.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All recommended substitute parts maintain ROHS3 compliance consistent with the original TSSA5U60. All parts also maintain MSL 1 (Unlimited) moisture sensitivity level and REACH Unaffected status.

Q: What is the temperature operating range difference between TSSA5U60 and substitute parts?

A: TSSA5U60 and TSSA5U60 M2G operate from -55°C to 150°C. Most substitute parts (B160, B260AQ, B360A series) extend the lower temperature limit to -65°C, providing wider operating range. This difference does not prevent substitution in applications operating within -55°C to 150°C range.

Q: Which substitute part should I select if my circuit requires 3 A?

A: B360A-E3/5AT or B360A-E3/61T are rated for 3 A average rectified current at 60 V reverse voltage. Both maintain DO-214AC (SMA) package compatibility and operating temperature range of -55°C to 150°C. Selection between the two depends on packaging format: CT & Digi-Reel (5AT) or Cut Tape only (61T).
