Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ160A-M3/52 is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 160V
• Voltage - Clamping (Max) @ Ipp: 259V (±tolerance acceptable)
• Current - Peak Pulse (10/1000µs): 2.3A (±tolerance acceptable)
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 150°C
• Type: Zener, Unidirectional

Substitute parts must maintain electrical equivalence within the specified parameter ranges and be compatible with the DO-214AA surface mount package. All identified substitutes meet these criteria and are classified as Active products with RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and full RoHS3 compliance, meeting regulatory and environmental requirements equivalent to the SMBJ160A-M3/52. The electrical parameters across all substitutes fall within acceptable tolerance ranges for TVS diode applications:

• SMBJ160D-M3/H (Vishay): Clamping voltage of 256V represents a 3V reduction from the primary part, with peak pulse current of 2.34A. This variant remains within functional equivalence for general-purpose transient suppression.

• SMBJ160A (Meritek): Electrical specifications match the primary part identically (259V clamping, 2.32A peak pulse). This part offers equivalent performance with different manufacturer sourcing.

• SMBJ160A-13-F (Diodes Incorporated): Specifications are identical to the primary part (259V clamping, 2.3A peak pulse) with SMB package designation. This part provides direct functional equivalence.

All substitutes are compatible with DO-214AA surface mount assembly processes and operate across the full -55°C to 150°C temperature range. Selection among these parts may be based on procurement availability, lead time, and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can SMBJ160D-M3/H replace SMBJ160A-M3/52 in my circuit?

A: Yes. The SMBJ160D-M3/H maintains the same 160V reverse standoff voltage and 600W peak pulse power rating. The clamping voltage difference of 3V (256V vs. 259V) is within acceptable tolerance for TVS diode substitution in general-purpose applications. Both parts use identical DO-214AA packaging and operating temperature ranges.

Q: Are there any differences in package compatibility between these substitutes?

A: All substitute parts use the DO-214AA (SMB) surface mount package. They are mechanically and electrically compatible with PCB layouts designed for the SMBJ160A-M3/52. No design modifications are required for package substitution.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All identified substitutes are RoHS3 compliant with MSL rating of 1 (Unlimited). They meet identical regulatory and environmental requirements as the primary part.

Q: What is the significance of the voltage clamping tolerance across these parts?

A: Voltage clamping tolerance reflects the maximum voltage the TVS diode will clamp during a transient event. The SMBJ160D-M3/H clamps at 256V compared to 259V for other variants. This 3V difference is within normal manufacturing tolerance for TVS diodes and does not affect functional equivalence in general-purpose protection circuits.

Q: Can I mix different manufacturers' parts in the same design?

A: Yes. All substitute parts meet identical electrical specifications, package requirements, and compliance standards. They are functionally equivalent and can be used interchangeably based on procurement and availability requirements.
