SMBJ110CE3/TR13 Equivalent & Substitute Parts

Part Overview

The SMBJ110CE3/TR13 is a transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection in surface-mount applications. This bidirectional Zener diode operates with a reverse standoff voltage of 110V and provides clamping protection at 196V maximum. The component is supplied in Tape & Reel packaging with DO-214AA (SMB) form factor and maintains Active product status with full RoHS3 compliance.

Equivalent and substitute parts are identified based on matching electrical performance parameters, mechanical compatibility, and operational characteristics. Substitutes must maintain identical reverse standoff voltage, breakdown voltage range, and surface-mount package specifications to ensure direct interchangeability in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ110CE3/TR13 are qualified based on the following critical electrical and mechanical parameters:

Matching Criteria:

• Reverse Standoff Voltage: 110V (typical)
• Breakdown Voltage (Minimum): 122V
• Package Type: DO-214AA / SMB surface mount
• Bidirectional Channels: 1
• Type: Zener diode
• Applications: General Purpose

Substitution Logic: The SMBJ110CA and SMBJ110CA-13-F are functionally equivalent to the SMBJ110CE3/TR13 because they maintain identical reverse standoff voltage (110V) and breakdown voltage specifications (122V minimum). Both substitute parts operate within the same voltage protection window and are housed in the same DO-214AA package form factor. While clamping voltage and peak pulse current specifications vary slightly between parts, the core protection function and circuit compatibility remain consistent across the SMBJ110 series.

Parameter Comparison

Engineering Selection Recommendations

SMBJ110CA (Fairchild Semiconductor): This substitute maintains Active product status and matches all critical electrical parameters required for direct substitution. The part operates across the same voltage protection range with identical reverse standoff and breakdown specifications. The clamping voltage of 177V is lower than the main part (196V), providing tighter voltage regulation. Peak pulse current capability is increased to 3.4A. Available in Bulk packaging format. RoHS3 compliance status is not specified in the provided data.

SMBJ110CA-13-F (Diodes Incorporated): This substitute is fully qualified for direct replacement, maintaining Active product status with ROHS3 compliance certification matching the main part. Electrical specifications are identical to the SMBJ110CA variant, with 177V clamping voltage and 3.4A peak pulse current. The part is supplied in Tape & Reel packaging, consistent with the main part's packaging format. Operating temperature range is -55 to 150°C, which is narrower than the main part's -65 to 150°C range but remains suitable for standard industrial applications.

Both substitute parts are suitable for applications where the SMBJ110CE3/TR13 is specified, provided that the lower clamping voltage (177V versus 196V) and higher peak pulse current (3.4A versus 3A) are acceptable within the circuit design parameters.

Frequently Asked Questions (FAQ)

Q: Can SMBJ110CA be used as a direct replacement for SMBJ110CE3/TR13?

A: Yes. Both parts share identical reverse standoff voltage (110V) and breakdown voltage (122V minimum), which are the primary parameters determining TVS diode substitutability. The SMBJ110CA operates in the same voltage protection window and uses the same DO-214AA package. The clamping voltage difference (177V versus 196V) represents improved voltage regulation performance in the substitute part.

Q: What is the difference between SMBJ110CA and SMBJ110CA-13-F?

A: Both parts have identical electrical specifications. The primary difference is packaging format: SMBJ110CA is supplied in Bulk packaging, while SMBJ110CA-13-F is supplied in Tape & Reel format. The SMBJ110CA-13-F also carries explicit ROHS3 compliance certification. Selection between these variants depends on procurement requirements and assembly process specifications.

Q: Does the lower clamping voltage in substitute parts affect circuit compatibility?

A: The substitute parts (SMBJ110CA and SMBJ110CA-13-F) clamp at 177V maximum, compared to 196V for the main part. This represents tighter voltage regulation and is generally beneficial for component protection. Compatibility depends on circuit design specifications. If the original design requires clamping at or above 196V, the substitute parts may not be suitable.

Q: Are the substitute parts RoHS3 compliant?

A: SMBJ110CA-13-F carries explicit ROHS3 compliance certification. SMBJ110CA compliance status is not specified in the provided data. The main part SMBJ110CE3/TR13 is ROHS3 compliant.

Q: What is the operating temperature difference between the main part and substitutes?

A: The main part operates from -65 to 150°C (TJ), while both substitute parts operate from -55 to 150°C (TJ). The substitute parts have a narrower low-temperature range by 10°C. For applications requiring operation below -55°C, the main part SMBJ110CE3/TR13 is required.

Q: Can packaging format (Tape & Reel versus Bulk) affect substitution decisions?

A: Packaging format does not affect electrical or mechanical compatibility. Selection between Tape & Reel and Bulk packaging depends on assembly process requirements, inventory management, and procurement specifications. SMBJ110CE3/TR13 and SMBJ110CA-13-F are both supplied in Tape & Reel format, while SMBJ110CA is supplied in Bulk format.
