SMBG130A-E3/5B Equivalent & Substitute Parts

Part Overview

The SMBG130A-E3/5B is a unidirectional transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates in the TransZorb® series and is designed for general-purpose transient voltage suppression applications. The device features a 130V reverse standoff voltage with a 209V maximum clamping voltage and 2.9A peak pulse current capability. The part maintains active product status and is RoHS3 compliant. Equivalent and substitute parts are identified when electrical performance parameters and mechanical compatibility align within acceptable tolerances for the intended application.

Substitute Part Grouping Explanation

Substitution of the SMBG130A-E3/5B is determined by equivalence in the following critical parameters:

• Voltage - Reverse Standoff: 130V (nominal)
• Voltage - Breakdown (Min): 144V
• Voltage - Clamping (Max) @ Ipp: 209V
• Current - Peak Pulse (10/1000µs): ≥2.9A
• Power - Peak Pulse: 600W
• Operating Temperature Range: -55°C to 150°C (TJ)
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant

The SMBJ130A-TR from STMicroelectronics meets all specified electrical parameters and compliance requirements. While the package designation differs (DO-214AA vs. DO-215AA), both are SMB form factors suitable for surface mount applications. The peak pulse current of the substitute (3A) exceeds the minimum requirement (2.9A), providing equivalent or superior performance.

Parameter Comparison

Engineering Selection Recommendations

The SMBJ130A-TR qualifies as a direct substitute for the SMBG130A-E3/5B based on electrical parameter equivalence and compliance alignment. Both components are active products with ROHS3 compliance and MSL Level 1 rating. The substitute part demonstrates equal or superior electrical performance across all critical parameters. Package compatibility is maintained through both devices utilizing SMB form factor surface mount construction, though the specific package designations differ (DO-215AA vs. DO-214AA). Selection between these parts may be determined by availability, lead time, or procurement requirements, as electrical and thermal performance are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the SMBJ130A-TR directly replace the SMBG130A-E3/5B in existing designs?

A: Yes. The SMBJ130A-TR meets all electrical specifications of the SMBG130A-E3/5B, including voltage ratings, clamping characteristics, and peak pulse current. Both components are surface mount SMB form factor devices with identical operating temperature ranges and RoHS compliance status.

Q: What is the difference between DO-215AA and DO-214AA packages?

A: Both designations refer to SMB form factor surface mount packages. DO-215AA and DO-214AA are functionally equivalent for PCB layout and assembly purposes. Verify footprint compatibility with your specific PCB design before implementation.

Q: Is the higher peak pulse current (3A vs. 2.9A) of the substitute part a concern?

A: No. The substitute part's 3A peak pulse current exceeds the original specification of 2.9A, providing equivalent or improved transient suppression capability within the same 600W power rating.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 rating. Compliance profiles are equivalent.

Q: What factors should determine part selection between these two options?

A: Selection should be based on component availability, procurement lead times, cost considerations, and existing supplier relationships. Electrical performance and compliance are equivalent, making either part suitable for the application.
