SMBJ60E3/TR13 Equivalent & Substitute Parts

Part Overview

The SMBJ60E3/TR13 is an active Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology, designed for general purpose transient protection applications. This unidirectional Zener-type device operates across a temperature range of -65°C to 150°C (TJ) and is supplied in tape and reel packaging with DO-214AA/SMB surface mount configuration. The availability of substitute parts ensures design flexibility and supply chain resilience for applications requiring equivalent transient suppression characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ60E3/TR13 are qualified based on strict electrical and mechanical compatibility criteria. The following parameters must match or remain functionally equivalent:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 60V
• Voltage - Breakdown (Min): 66.7V
• Unidirectional Channels: 1
• Package / Case: DO-214AA / SMB (surface mount)
• Mounting Type: Surface Mount
• Product Status: Active
• Power - Peak Pulse: 600W

Acceptable Variation Parameters:

• Voltage - Clamping (Max) @ Ipp: 96.8V to 107V (substitute range maintains protective functionality within design specifications)
• Current - Peak Pulse (10/1000µs): 5.6A to 6.2A (within comparable transient suppression capability)
• Operating Temperature Range: -50°C to -65°C minimum; 150°C maximum (all substitutes maintain full upper thermal specification)

The substitute parts SMBJ60A (MDD) and SMBJ60A-13-F (Diodes Incorporated) share the same base product number designation and meet all critical matching and acceptable variation parameters, confirming their status as qualified equivalents.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring availability and regulatory alignment with the original SMBJ60E3/TR13 specification.

SMBJ60A (MDD): Shares identical electrical specifications with the exception of voltage clamping and peak pulse current within acceptable variation ranges. Inventory availability of 27,296 units provides supply assurance. Operating temperature minimum of -50°C versus -65°C on the original part may require evaluation if designs operate in extended low-temperature environments.

SMBJ60A-13-F (Diodes Incorporated): Supplied in tape and reel packaging matching the original part's delivery format. Operating temperature range of -55°C to 150°C provides extended low-temperature coverage between the MDD variant and the original Microchip part. Inventory of 3,036 units available. This variant aligns most closely with the packaging and thermal specifications of the original SMBJ60E3/TR13.

Frequently Asked Questions (FAQ)

Q: Can SMBJ60A parts substitute for SMBJ60E3/TR13 in high-temperature applications? A: Both substitute parts maintain the 150°C upper operating temperature limit specified on the original part. Applications with elevated temperature requirements remain fully supported.

Q: What is the difference in voltage clamping between the original part and substitutes? A: The SMBJ60E3/TR13 specifies a maximum clamping voltage of 107V, while SMBJ60A parts specify 96.8V. Both remain within the same 60V reverse standoff and 66.7V breakdown specifications. The lower clamping value on substitutes provides equal or improved transient suppression performance.

Q: Are package dimensions and pin configurations identical across all three parts? A: Yes. All three parts use DO-214AA/SMB surface mount packages with identical mechanical footprints and pin configurations, enabling direct PCB-level substitution.

Q: Which substitute part has the best inventory position? A: MDD SMBJ60A has the highest inventory level at 27,296 pieces. Diodes Incorporated SMBJ60A-13-F provides an alternative with 3,036 pieces in stock.

Q: Does the higher peak pulse current on SMBJ60A parts affect circuit design? A: The SMBJ60A specification of 6.2A peak pulse current versus 5.6A on the original part indicates equivalent or superior transient handling capability. No circuit redesign is required.

Q: Can I use parts with -50°C minimum temperature specification in -65°C environments? A: MDD SMBJ60A is specified for -50°C minimum operation. Diodes Incorporated SMBJ60A-13-F extends to -55°C. If designs require operation at -65°C, only the original SMBJ60E3/TR13 or equivalent extended-range variants are appropriate.
