SMBJ7.5CA-TP Transient Voltage Suppressor (TVS) Diode - Equivalent & Substitute Parts

Part Overview

The SMBJ7.5CA-TP is a surface mount transient voltage suppressor diode manufactured by Micro Commercial Co, designed for general purpose overvoltage protection applications. This bidirectional zener TVS diode operates with a 7.5V reverse standoff voltage and provides 12.9V maximum clamping voltage at peak pulse current. The component is packaged in DO-214AA (SMB) format and is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1). The part is currently in active production status with 2991 units in stock.

Equivalent and substitute parts are necessary when the primary part number becomes unavailable, when alternative manufacturers offer improved lead times or pricing, or when design flexibility permits selection from multiple qualified sources meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ7.5CA-TP is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 7.5V
• Voltage - Breakdown (Min): 8.33V
• Voltage - Clamping (Max) @ Ipp: 12.9V
• Current - Peak Pulse (10/1000µs): 46.5A minimum
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Bidirectional Channels: 1
• Type: Zener
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical requirements. Variations in operating temperature range, packaging format (Tape & Reel vs. Cut Tape), and manufacturer series designation do not affect functional substitutability in applications where the SMBJ7.5CA-TP is specified.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active production status and full RoHS3 compliance with MSL 1 rating, confirming suitability for direct replacement in applications currently specified for SMBJ7.5CA-TP.

The SMBJ7.5CA variant from MDD exhibits marginally higher peak pulse current (46.6A vs. 46.5A) and operates within a narrower temperature range (-50°C to 150°C compared to -55°C to 175°C). This part remains functionally equivalent for applications not requiring the extended upper temperature limit of the original specification.

SMBJ7.5CA-13-F from Diodes Incorporated, SMBJ7.5CA-E3/52 from Vishay, and SMBJ7V5CA from Taiwan Semiconductor Corporation all maintain the full electrical specification and temperature range compatibility with the primary part, differing only in packaging format (Tape & Reel) and manufacturer series designation.

Selection among these substitutes should be based on availability, lead time, and procurement requirements, as all parts satisfy the electrical and compliance requirements of the SMBJ7.5CA-TP specification.

Frequently Asked Questions (FAQ)

Q: Can SMBJ7.5CA from MDD be used as a direct replacement for SMBJ7.5CA-TP?

A: Yes. The MDD variant meets all critical electrical parameters including 7.5V reverse standoff, 12.9V clamping voltage, and 46.6A peak pulse current. The operating temperature range is -50°C to 150°C, which is narrower than the original -55°C to 175°C specification. Substitution is valid for applications not requiring operation at temperatures below -50°C or above 150°C.

Q: What is the difference between SMBJ7.5CA-E3/52 and SMBJ7.5CA-TP?

A: Both parts are electrically identical with 7.5V standoff voltage, 12.9V clamping voltage, and 46.5A peak pulse current. The primary difference is the manufacturer (Vishay vs. Micro Commercial Co) and packaging format (Tape & Reel). The SMBJ7.5CA-E3/52 operates from -55°C to 150°C, compared to -55°C to 175°C for the original part.

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

A: Yes. All substitute parts are packaged in DO-214AA (SMB) format and are surface mount components suitable for identical PCB footprints and reflow soldering processes.

Q: Do all substitute parts have the same RoHS and MSL compliance?

A: Yes. All substitute parts are RoHS3 compliant with MSL 1 (unlimited moisture sensitivity), matching the compliance profile of SMBJ7.5CA-TP.

Q: Which substitute part has the widest operating temperature range?

A: SMBJ7.5CA-TP and SMBJ7.5CA-13-F both operate from -55°C to 175°C and -55°C to 150°C respectively. The original SMBJ7.5CA-TP maintains the widest upper temperature limit at 175°C. For applications requiring operation above 150°C, the original part or SMBJ7.5CA-13-F should be specified.

Q: Can SMBJ7V5CA from Taiwan Semiconductor Corporation replace SMBJ7.5CA-TP?

A: Yes. SMBJ7V5CA meets all electrical specifications with 7.5V standoff voltage, 12.9V clamping voltage, and 46.5A peak pulse current. Operating temperature range is -55°C to 150°C. The part is available in Cut Tape and Digi-Reel packaging formats.
