SMBJ130 Equivalent & Substitute Parts

Part Overview

The SMBJ130 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection in surface-mount applications. The device features a 130V reverse standoff voltage with a 219.45V maximum clamping voltage and 2.9A peak pulse current capability in a DO-214AA (SMB) package. The SMBJ130 is classified as obsolete, necessitating identification of active equivalent parts that maintain electrical and mechanical compatibility for new designs and production continuity.

Engineering Selection Recommendations

All listed substitute parts are in active production status, providing immediate availability and long-term supply chain security compared to the obsolete SMBJ130. Each substitute maintains ROHS3 compliance and MSL Level 1 rating, meeting environmental and reliability requirements.

SMBJ130A (MDD) offers the highest inventory availability at 55,100 pieces and is suitable for applications where the -50°C lower operating temperature limit is acceptable.

SMBJ130A-13-F (Diodes Incorporated) is supplied in Tape & Reel packaging with 4,200 pieces in stock and supports the extended -55°C lower temperature range.

SMBJ130A-E3/52 (Vishay TransZorb®) provides 29,300 pieces in Tape & Reel format with -55°C lower temperature capability, offering a balance of availability and temperature performance.

SMBJ130A-E3/5B (Vishay TransZorb®) is available in Cut Tape & Digi-Reel® packaging with 2,900 pieces in stock and -55°C lower temperature support, suitable for lower-volume or mixed-packaging requirements.

All substitute parts are rated for the same 600W peak pulse power and 2.9A peak pulse current, with clamping voltages within 209V (all substitutes) compared to the original 219.45V specification. The voltage differential of approximately 10V represents a tighter clamping characteristic, which is acceptable for general-purpose transient suppression applications.

Frequently Asked Questions (FAQ)

Q: Can SMBJ130A parts directly replace the obsolete SMBJ130?

A: Yes. All substitute parts maintain the same 130V reverse standoff voltage, 2.9A peak pulse current, 600W peak pulse power rating, and DO-214AA (SMB) surface-mount package. Electrical performance is equivalent within specified tolerances.

Q: What is the difference between the 219.45V and 209V clamping voltages?

A: The original SMBJ130 specifies a maximum clamping voltage of 219.45V, while all substitute parts specify 209V. This 10V difference represents a tighter clamping characteristic in the substitute parts, which provides improved transient suppression performance and is acceptable for general-purpose applications.

Q: Are there temperature range differences between substitutes?

A: Yes. The SMBJ130A (MDD) operates from -50°C to 150°C, while SMBJ130A-13-F (Diodes Inc.), SMBJ130A-E3/52 (Vishay), and SMBJ130A-E3/5B (Vishay) all support -55°C to 150°C. The original SMBJ130 supported -65°C to 150°C. For applications requiring operation below -55°C, alternative solutions should be evaluated.

Q: What packaging options are available?

A: SMBJ130A (MDD) is available in standard packaging. SMBJ130A-13-F (Diodes Inc.) and SMBJ130A-E3/52 (Vishay) are supplied in Tape & Reel (TR) format. SMBJ130A-E3/5B (Vishay) is available in Cut Tape (CT) & Digi-Reel® format. All maintain the same DO-214AA (SMB) component package.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All substitute parts are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original SMBJ130 environmental specifications.

Q: Which substitute offers the best inventory availability?

A: SMBJ130A (MDD) provides the highest stock level at 55,100 pieces. SMBJ130A-E3/52 (Vishay) offers 29,300 pieces, SMBJ130A-13-F (Diodes Inc.) provides 4,200 pieces, and SMBJ130A-E3/5B (Vishay) has 2,900 pieces available.
