SMBJ60CA-13 Equivalent & Substitute Parts

Part Overview

The SMBJ60CA-13 is a Transient Voltage Suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose transient protection applications. This surface-mount component features a 60V reverse standoff voltage with a 96.8V maximum clamping voltage and 6.2A peak pulse current capability in the SMB (DO-214AA) package. The SMBJ60CA-13 is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution of the SMBJ60CA-13 is determined by strict equivalence across the following electrical and mechanical parameters:

Voltage - Reverse Standoff (Typ): 60V
Voltage - Breakdown (Min): 66.7V
Voltage - Clamping (Max) @ Ipp: 96.8V
Current - Peak Pulse (10/1000µs): 6.2A
Power - Peak Pulse: 600W
Package / Case: DO-214AA, SMB
Mounting Type: Surface Mount
Bidirectional Channels: 1

All identified substitute parts maintain these core electrical specifications and physical package requirements, ensuring functional compatibility in the original application circuit.

Engineering Selection Recommendations

SMBJ60CA-13-F (Diodes Incorporated) is the direct equivalent substitute, maintaining identical electrical specifications and operating temperature range as the original SMBJ60CA-13. This part is currently active and ROHS3 compliant, addressing the discontinuation status of the original component.

SMBJ60CA (MDD) provides electrical equivalence with ROHS3 compliance and active product status. The operating temperature range extends to -50°C minimum (versus -55°C for the original), which is acceptable for most general-purpose applications. High inventory availability supports production continuity.

SZ1SMB60CAT3G (Littelfuse Inc.) maintains full electrical equivalence and offers the widest operating temperature range (-65 to 150°C). This part carries AEC-Q101 automotive qualification and is ROHS3 compliant, making it suitable for applications requiring automotive-grade reliability or extended temperature performance.

Frequently Asked Questions (FAQ)

Q: Can SMBJ60CA-13-F be used as a direct replacement for SMBJ60CA-13?

A: Yes. SMBJ60CA-13-F is electrically and mechanically identical to SMBJ60CA-13, with the primary difference being packaging format (Tape & Reel) and active product status. Both maintain the same voltage ratings, current specifications, and operating temperature range.

Q: What is the difference between SMBJ60CA-13 and SMBJ60CA?

A: SMBJ60CA-13 is the Diodes Incorporated part number suffix variant. SMBJ60CA (MDD) is the base part number from a different manufacturer. Both share identical electrical specifications (60V standoff, 96.8V clamp, 6.2A peak pulse). The MDD variant has a slightly higher minimum operating temperature (-50°C vs -55°C).

Q: Is SZ1SMB60CAT3G suitable for automotive applications?

A: Yes. SZ1SMB60CAT3G carries AEC-Q101 automotive qualification and is rated for -65 to 150°C operating temperature, making it appropriate for automotive and extended-temperature environments while maintaining full electrical equivalence.

Q: Are all substitute parts available in the same SMB package?

A: Yes. All substitute parts use the DO-214AA (SMB) surface-mount package, ensuring identical PCB footprint and assembly compatibility with the original SMBJ60CA-13.

Q: What is the significance of RoHS compliance differences?

A: The original SMBJ60CA-13 is RoHS non-compliant, while all active substitutes (SMBJ60CA-13-F, SMBJ60CA, SZ1SMB60CAT3G) are ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the compliant substitutes are necessary.
