SMAJ60A-13 Equivalent & Substitute Parts

Part Overview

The SMAJ60A-13 is a unidirectional Zener transient voltage suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose overvoltage protection in surface-mount applications. The device features a 60V reverse standoff voltage with 96.8V maximum clamping voltage and 4.1A peak pulse current capability in a DO-214AC (SMA) package. This part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility for ongoing production and repair applications.

Substitute Part Grouping Explanation

Substitution eligibility for the SMAJ60A-13 is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage - Reverse Standoff: 60V (±tolerance as specified by manufacturer)
• Voltage - Breakdown (Min): 66.7V minimum
• Voltage - Clamping (Max) @ Ipp: 96.8V maximum
• Current - Peak Pulse (10/1000µs): 4.1A minimum
• Power - Peak Pulse: 400W minimum
• Package / Case: DO-214AC (SMA) or mechanically compatible equivalent
• Mounting Type: Surface Mount
• Type: Zener, Unidirectional (1 channel)
• Operating Temperature: -55°C to 150°C minimum range

Substitute parts are grouped into three categories based on manufacturer and packaging configuration: direct Diodes Incorporated variants with different packaging formats, alternative manufacturer equivalents with identical electrical specifications, and manufacturer-recommended alternatives with different package geometries.

Parameter Comparison

Engineering Selection Recommendations

SMAJ60A-13-F (Diodes Incorporated) is the primary direct substitute. This part maintains identical electrical specifications and DO-214AC (SMA) package geometry while offering Tape & Reel packaging format. Product status is Active with ROHS3 compliance and significantly higher inventory availability (15,955 units), making it the preferred choice for direct replacement in existing designs without PCB modification.

SMAJ60A (Meritek) provides electrical equivalence with 4.13A peak pulse current (within specification tolerance) and identical voltage parameters. The part is Active with ROHS3 compliance and the highest inventory level (77,620 units). DO-214AC (SMA) package compatibility ensures mechanical interchangeability without design changes.

SMAJ60A-TP (Micro Commercial Co) maintains full electrical and mechanical compatibility with DO-214AC (SMA) packaging and extends the operating temperature range to 175°C. Product status is Active with ROHS3 compliance. Cut Tape packaging format is suitable for automated assembly processes.

PTVS60VS1UR,115 (Nexperia USA Inc.) meets all electrical specifications but uses SOD-123W package geometry, which differs from the original DO-214AC (SMA) footprint. This part carries AEC-Q101 automotive qualification and is ROHS3 compliant. Selection requires PCB layout modification to accommodate the different package dimensions and pin configuration.

Frequently Asked Questions (FAQ)

Q: Can SMAJ60A-13-F be used as a direct drop-in replacement for SMAJ60A-13?

A: Yes. SMAJ60A-13-F maintains identical electrical specifications (60V standoff, 96.8V clamping, 4.1A peak pulse) and uses the same DO-214AC (SMA) package. The only difference is packaging format (Tape & Reel vs. bulk), which does not affect electrical performance or PCB compatibility.

Q: What is the difference between SMAJ60A from Meritek and the original Diodes part?

A: The Meritek SMAJ60A has a peak pulse current specification of 4.13A compared to 4.1A for the Diodes part. Both meet the 4.1A minimum requirement. Electrical voltage parameters are identical. Both use DO-214AC (SMA) packages and are ROHS3 compliant.

Q: Why does PTVS60VS1UR,115 require PCB modification?

A: The PTVS60VS1UR,115 uses SOD-123W package geometry, which has different physical dimensions and pin spacing compared to the DO-214AC (SMA) package of the original part. PCB footprint redesign is necessary for mechanical fit and electrical connection.

Q: Are all substitute parts RoHS compliant?

A: SMAJ60A-13-F, SMAJ60A (Meritek), SMAJ60A-TP, and PTVS60VS1UR,115 are all ROHS3 compliant. The original SMAJ60A-13 is RoHS non-compliant. For applications requiring RoHS compliance, any of the four substitute parts are acceptable.

Q: Which substitute part has the widest operating temperature range?

A: SMAJ60A-TP (Micro Commercial Co) extends the operating temperature range to -55°C to 175°C, compared to -55°C to 150°C for the original part and other substitutes. This provides additional thermal margin for high-temperature applications.

Q: Can I use PTVS60VS1UR,115 in automotive applications?

A: Yes. PTVS60VS1UR,115 carries AEC-Q101 automotive qualification. However, PCB layout modification is required due to the different SOD-123W package. The other substitutes do not carry automotive qualification markings.

Q: What inventory considerations should guide part selection?

A: SMAJ60A (Meritek) offers the highest inventory level at 77,620 units. PTVS60VS1UR,115 (Nexperia) has 20,843 units available. SMAJ60A-TP (MCC) has 24,144 units. SMAJ60A-13-F (Diodes) has 15,955 units. For high-volume production, Meritek or Nexperia options provide superior supply security.
