SMAJ9.0A-TP Equivalent & Substitute Parts
Part Overview
The SMAJ9.0A-TP is a unidirectional transient voltage suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection in surface-mount applications. This component features a 9V reverse standoff voltage with a 15.4V maximum clamping voltage and 26A peak pulse current capability in a DO-214AC (SMA) package. The part is active in production status and RoHS3 compliant. Equivalent and substitute parts are identified based on matching electrical performance parameters and package compatibility to support procurement flexibility and supply chain continuity.

Substitute Part Grouping Explanation
Substitute parts for the SMAJ9.0A-TP are qualified based on the following electrical and mechanical parameters:
- Voltage - Reverse Standoff: 9V
- Voltage - Breakdown (Min): 10V
- Voltage - Clamping (Max) @ Ipp: 15.4V
- Current - Peak Pulse (10/1000µs): 26A
- Power - Peak Pulse: 400W
- Package / Case: DO-214AC, SMA
- Mounting Type: Surface Mount
- Type: Zener, Unidirectional (1 channel)
- RoHS Status: ROHS3 Compliant
All identified substitute parts match these core parameters and are therefore electrically and mechanically interchangeable with the SMAJ9.0A-TP in applications requiring 9V TVS protection with SMA package form factor.

Engineering Selection Recommendations
All four parts listed—SMAJ9.0A-TP, SMAJ9.0A (MDD), SMAJ9.0A-13-F, and SMAJ9.0A-E3/61—are active production components with ROHS3 compliance and identical electrical specifications. Selection among these parts may be based on:
- Manufacturer availability and supply chain requirements
- Inventory levels and lead times
- Operating temperature range requirements (SMAJ9.0A-TP supports -55°C to 175°C; others support -55°C to 150°C or -50°C to 150°C)
- Packaging and tape & reel specifications
- Compliance certifications (all are REACH Unaffected and EAR99 classified)
Frequently Asked Questions (FAQ)
Q: Can SMAJ9.0A (MDD) be used as a direct replacement for SMAJ9.0A-TP?
A: Yes. Both parts share identical electrical parameters (9V standoff, 15.4V clamping, 26A peak pulse) and the same DO-214AC (SMA) package. The primary difference is the operating temperature range: SMAJ9.0A-TP operates to 175°C ambient, while SMAJ9.0A (MDD) operates to 150°C junction temperature. For applications within the MDD part's temperature range, direct substitution is valid.
Q: What is the difference between SMAJ9.0A-13-F and SMAJ9.0A-E3/61?
A: Both parts are electrically identical with matching 9V/15.4V/26A specifications and SMA packaging. SMAJ9.0A-13-F is manufactured by Diodes Incorporated, while SMAJ9.0A-E3/61 is manufactured by Vishay (TransZorb® series). Inventory availability and supplier relationships typically determine selection between these two.
Q: Are all substitute parts available in Tape & Reel packaging?
A: Yes. All identified substitute parts are supplied in Tape & Reel (TR) packaging, maintaining consistency with the original SMAJ9.0A-TP specification for automated assembly processes.
Q: Do all parts meet the same compliance standards?
A: Yes. All parts are ROHS3 compliant, REACH Unaffected, and classified as EAR99 for export control purposes. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts.
Q: Can these parts be used interchangeably in PCB designs?
A: Yes. All substitute parts use the identical DO-214AC (SMA) package footprint and are rated for the same electrical stress conditions (9V standoff, 15.4V clamping, 26A peak pulse, 400W peak power). PCB layouts and designs require no modification when substituting between these parts.
