SMBJ130C-E3/52 Equivalent & Substitute Parts

Part Overview

The SMBJ130C-E3/52 is a transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division, designed for general-purpose overvoltage protection in surface-mount applications. This component features a 130V reverse standoff voltage with a 231V maximum clamping voltage and 2.6A peak pulse current capability in a DO-214AA (SMB) package.

The SMBJ130C-E3/52 is classified as obsolete. Equivalent and substitute parts listed below provide active alternatives with compatible electrical and mechanical specifications suitable for direct replacement in circuit designs.

Substitute Part Grouping Explanation

Substitute parts for the SMBJ130C-E3/52 are qualified based on the following electrical and mechanical compatibility criteria:

Primary Substitution Criteria:

Reverse standoff voltage: 130V (Typ)
Breakdown voltage minimum: 144V
Package type: DO-214AA (SMB) surface mount
Bidirectional channels: 1
Type: Zener TVS diode
RoHS3 compliance and MSL 1 rating

Secondary Compatibility Parameters:

Clamping voltage range: 209V to 231V @ Ipp
Peak pulse current: 2.6A to 2.9A
Peak pulse power: 600W
Operating temperature: -55°C to -65°C minimum; 150°C maximum

Substitute parts are grouped into two categories based on clamping voltage specification: parts matching the original 231V clamping voltage, and parts with 209V clamping voltage that remain within acceptable operating parameters for general-purpose transient suppression applications.

Engineering Selection Recommendations

Direct Electrical Match (231V Clamping): SMBJ130CE3/TR13 (Microchip Technology) provides identical clamping voltage performance to the original SMBJ130C-E3/52 with extended operating temperature range (-65°C minimum). This part is active and available in tape & reel packaging.

Functional Equivalent (209V Clamping): SMBJ130CA-E3/52 (Vishay General Semiconductor), SMBJ130CA (Meritek), SMBJ130CA-13-F (Diodes Incorporated), and SMBJ130CAE3/TR13 (Microchip Technology) operate at 209V clamping voltage with peak pulse currents of 2.87A to 2.9A. These parts maintain the 130V reverse standoff specification and are suitable for applications where the lower clamping voltage remains within circuit protection requirements. All are active products with ROHS3 compliance and MSL 1 rating.

All substitute parts are available in DO-214AA (SMB) surface-mount packaging and maintain compatibility with existing PCB layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can SMBJ130CA-E3/52 replace SMBJ130C-E3/52 directly? A: Yes. Both parts share the same 130V reverse standoff voltage, DO-214AA package, and operating temperature range. The SMBJ130CA-E3/52 operates at 209V clamping voltage compared to the original 231V, with slightly higher peak pulse current (2.9A vs. 2.6A). This substitution is valid for general-purpose transient suppression where the lower clamping voltage meets circuit requirements.

Q: What is the difference between 231V and 209V clamping voltage specifications? A: Clamping voltage determines the maximum voltage the TVS diode allows across its terminals during a transient event. The 231V specification provides tighter voltage regulation at the expense of slightly lower peak pulse current handling. The 209V specification offers higher current capacity with marginally higher voltage transients. Selection depends on the specific overvoltage protection threshold required by the protected circuit.

Q: Are all substitute parts available in tape & reel packaging? A: Yes. All listed substitute parts are supplied in tape & reel (TR) packaging suitable for automated assembly. The original SMBJ130C-E3/52 was supplied in bulk packaging; tape & reel alternatives are standard for active production parts.

Q: Do substitute parts meet the same compliance standards? A: Yes. All substitute parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level) rating, matching the original part's environmental and regulatory compliance profile.

Q: Which substitute offers the widest operating temperature range? A: SMBJ130CE3/TR13 and SMBJ130CAE3/TR13 (both Microchip Technology) specify -65°C minimum operating temperature compared to -55°C for other alternatives, providing extended low-temperature performance.
