SMDJ130 Equivalent & Substitute Parts

Part Overview

The SMDJ130 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection in surface-mount applications. This component features a 130V reverse standoff voltage with a 219.45V maximum clamping voltage and 14.4A peak pulse current capability in a DO-214AB (SMC) package. The SMDJ130 is currently obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMDJ130 are qualified based on the following critical parameters that must remain consistent:

• Voltage - Reverse Standoff (Typ): 130V
• Unidirectional Channels: 1
• Mounting Type: Surface Mount
• Package / Case: DO-214AB, SMC
• Type: Zener
• Applications: General Purpose

Substitutes are grouped into two categories based on peak pulse current and power dissipation capacity:

High Current Group (14.4A / 3000W): Parts maintaining the original 14.4A peak pulse current and 3000W power rating. These provide direct functional equivalence with identical electrical performance.

Standard Current Group (7.18A - 7.2A / 1500W): Parts with reduced peak pulse current (approximately 50% of original) and proportionally reduced power dissipation. These are suitable for applications with lower transient energy requirements.

All substitute parts maintain the 130V reverse standoff voltage, 209V clamping voltage (within acceptable range of original 219.45V), and DO-214AB package compatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are ROHS3 compliant and carry active product status, ensuring long-term availability and supply chain stability. The SMDJ130A from Alpha & Omega Semiconductor Inc. provides the closest electrical match with identical 14.4A peak pulse current and 3000W power dissipation, maintaining full functional equivalence with the obsolete SMDJ130.

For applications requiring the original 14.4A / 3000W performance envelope, SMDJ130A, SMLJ130A, SMLJ130A-TP, and TV30C131J-G are direct substitutes. These parts maintain identical peak pulse current and power ratings while operating within the specified 130V reverse standoff voltage window.

For applications with reduced transient energy requirements, SMCJ130A, SMCJ130A-TP, TV15C131J-G, and SMCJ130AE3/TR13 provide functional substitution with 7.18A to 7.2A peak pulse current and 1500W power dissipation. These parts are suitable where transient pulse energy is lower than the original design specification.

Temperature range considerations: SMCJ130A-TP and SMLJ130A-TP extend the upper operating temperature to 175°C, compared to 150°C for most alternatives. SMCJ130AE3/TR13 maintains the original -65°C lower temperature limit, matching the SMDJ130 specification.

Frequently Asked Questions (FAQ)

Q: Can SMCJ130A replace SMDJ130 in all applications?

A: SMCJ130A maintains the 130V reverse standoff voltage and DO-214AB package compatibility. However, it provides 7.18A peak pulse current versus the original 14.4A. Substitution is valid only for applications where transient pulse energy does not exceed 1500W. Verify circuit transient specifications before selection.

Q: What is the difference between SMLJ130A and SMDJ130A?

A: Both parts provide 14.4A peak pulse current and 3000W power dissipation. SMLJ130A is manufactured by Bourns Inc., while SMDJ130A is from Alpha & Omega Semiconductor Inc. Both are electrically equivalent and use the DO-214AB package. Selection may depend on supplier availability and procurement preferences.

Q: Are all substitute parts available in tape and reel packaging?

A: Packaging varies by manufacturer and part number. SMDJ130A, SMCJ130A-TP, SMCJ130AE3/TR13, SMLJ130A, SMLJ130A-TP, TV15C131J-G, and TV30C131J-G are available in tape and reel (TR) format. Verify packaging specifications with your supplier for production requirements.

Q: Does operating temperature range affect substitution suitability?

A: The SMDJ130 operates from -65°C to 150°C. Most substitutes operate from -55°C to 150°C, which is acceptable for most applications. SMCJ130A-TP and SMLJ130A-TP extend to 175°C. SMCJ130AE3/TR13 matches the original -65°C lower limit. Confirm your application's temperature requirements before final selection.

Q: Can I use TV30C131J-G as a direct replacement for SMDJ130?

A: TV30C131J-G from Comchip Technology provides 14.35A peak pulse current and 3000W power dissipation, maintaining functional equivalence with the SMDJ130. It uses the DO-214AB package and operates within the 130V reverse standoff specification. This part is suitable for direct substitution in equivalent circuit designs.
