SMBJ110A-M3/52 Equivalent & Substitute Parts

Part Overview

The SMBJ110A-M3/52 is a unidirectional Transient Voltage Suppressor (TVS) diode from Vishay General Semiconductor - Diodes Division, designed for general-purpose overvoltage protection in surface-mount applications. Manufactured in the DO-214AA (SMB) package, this component operates across a temperature range of -55°C to 150°C and maintains active product status with full RoHS3 compliance.

Substitute parts are necessary when the primary part number becomes unavailable, when alternative packaging configurations are required, or when sourcing from multiple manufacturers is needed to ensure supply chain continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ110A-M3/52 is determined by the following critical parameters:

Voltage - Reverse Standoff (Typ): 110V
Voltage - Clamping (Max) @ Ipp: 177V ± tolerance
Current - Peak Pulse (10/1000µs): 3.4A ± tolerance
Power - Peak Pulse: 600W
Package / Case: DO-214AA, SMB
Mounting Type: Surface Mount
Operating Temperature Range: -55°C to 150°C minimum
RoHS3 Compliance: Required

All substitute parts listed maintain identical or equivalent electrical performance within the specified parameter ranges and are housed in the same DO-214AA (SMB) surface-mount package. Substitutes differ only in manufacturer designation, packaging format (Tape & Reel vs. Cut Tape), or minor voltage clamping variations within acceptable tolerances.

Engineering Selection Recommendations

All listed substitute parts maintain active product status and full RoHS3 compliance, meeting the regulatory and environmental requirements of the original SMBJ110A-M3/52.

SMBJ110A-E3/52 (Vishay) is the manufacturer-recommended substitute, offering identical electrical specifications and packaging configuration with significantly higher inventory availability (45,300 units vs. 667 units for the primary part).

SMBJ110D-M3/H (Vishay) provides a functionally equivalent alternative with voltage clamping of 174V (within acceptable tolerance of the 177V specification) and marginally higher peak pulse current (3.45A vs. 3.4A). This part is available in substantially higher quantities (7,292 units).

SMBJ110A-13-F (Diodes Incorporated) offers identical electrical performance with alternative packaging format (Cut Tape & Digi-Reel® vs. Tape & Reel), suitable for applications requiring different supply configurations.

SMBJ110A (MDD) provides electrical equivalence with a minimum operating temperature of -50°C (compared to -55°C for the primary part), appropriate for applications not requiring extended low-temperature operation.

Frequently Asked Questions (FAQ)

Q: Can SMBJ110D-M3/H be used as a direct replacement for SMBJ110A-M3/52?

A: Yes. Both parts maintain the same 110V reverse standoff voltage, 600W peak pulse power, and DO-214AA package. The voltage clamping difference (174V vs. 177V) and peak pulse current difference (3.45A vs. 3.4A) fall within acceptable tolerance ranges for TVS diode substitution in general-purpose applications.

Q: What is the difference between SMBJ110A-M3/52 and SMBJ110A-E3/52?

A: Both parts are manufactured by Vishay with identical electrical specifications (110V standoff, 177V clamping, 3.4A peak pulse current). The difference lies in packaging designation and inventory availability. SMBJ110A-E3/52 is the manufacturer-recommended part with substantially higher stock levels.

Q: Are all substitute parts available in the same DO-214AA package?

A: Yes. All listed substitutes are housed in the DO-214AA (SMB) surface-mount package, ensuring mechanical and electrical compatibility with the original design.

Q: Does the MDD SMBJ110A have any temperature limitations compared to the primary part?

A: The MDD SMBJ110A operates from -50°C to 150°C, compared to -55°C to 150°C for the Vishay SMBJ110A-M3/52. This represents a 5°C reduction in minimum operating temperature. Selection should be based on application requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, meeting the same regulatory and environmental standards as the primary part.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging is supplied on continuous carrier tape suitable for automated pick-and-place assembly. Cut Tape & Digi-Reel® packaging provides individual tape segments, offering flexibility for lower-volume or mixed-component assembly processes. Both formats contain identical components.
