SMCJ130C Equivalent & Substitute Parts

Part Overview

The SMCJ130C is a 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 7.2A peak pulse current capability in a DO-214AB (SMC) package. The SMCJ130C is currently listed as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution for the SMCJ130C is determined by strict equivalence in the following electrical and mechanical parameters:

Voltage - Reverse Standoff: 130V (required match)
Voltage - Clamping (Max) @ Ipp: 209V to 231V (acceptable range for this application class)
Current - Peak Pulse: 7.2A minimum (7.18A acceptable; 14.4A acceptable with higher power rating)
Power - Peak Pulse: 1500W minimum (3000W acceptable)
Package / Case: DO-214AB, SMC (required match)
Mounting Type: Surface Mount (required match)
Type: Zener, Bidirectional, 1 Channel (required match)

Substitute parts are grouped into two categories based on peak pulse current capability: standard 7.2A devices and higher-capacity 14.4A devices. All listed substitutes maintain the 130V standoff voltage and DO-214AB package requirement.

Engineering Selection Recommendations

All listed substitute parts are ROHS3 compliant and maintain MSL 1 (Unlimited) moisture sensitivity rating, matching the original SMCJ130C specifications.

For direct electrical equivalence with the original SMCJ130C, select from the 7.2A peak pulse current devices: SMCJ130CA-TP, SMCJ130CAE3/TR13, TV15C131JB-G, or TV15C131JB-HF. These parts maintain the 1500W power rating and 209V clamping voltage within acceptable tolerance.

For applications requiring enhanced transient protection margin, the SMLJ130CA and SMLJ130CA-TP devices provide double the peak pulse current (14.4A) and power dissipation (3000W) while maintaining the 130V standoff voltage and DO-214AB package footprint. These higher-capacity devices are suitable for designs with increased surge stress or thermal margin requirements.

The SMCJ130CE3/TR13 variant offers a higher clamping voltage (231V) and lower peak pulse current (6.5A), suitable for applications where clamping voltage must be minimized or where lower current transients are expected.

Frequently Asked Questions (FAQ)

Q: Can SMLJ130CA (14.4A) be used as a direct replacement for SMCJ130C (7.2A)?

A: Yes. The SMLJ130CA maintains the same 130V reverse standoff voltage, DO-214AB package, and surface-mount configuration. The higher peak pulse current (14.4A) and power rating (3000W) provide additional protection margin without affecting circuit compatibility. The clamping voltage (209V) is within acceptable range for this device class.

Q: What is the difference between SMCJ130CA-TP and SMCJ130CAE3/TR13?

A: Both devices share identical electrical specifications (130V standoff, 209V clamping, 7.2A peak pulse). The primary difference is operating temperature range: SMCJ130CA-TP operates from -55°C to 175°C, while SMCJ130CAE3/TR13 operates from -65°C to 150°C. Select based on application temperature requirements.

Q: Are TV15C131JB-G and TV15C131JB-HF interchangeable?

A: Yes. Both Comchip Technology parts are electrically identical (130V standoff, 209V clamping, 7.18A peak pulse, 1500W power) and use the same DO-214AB package. The suffix designations (-G and -HF) indicate different manufacturing or packaging variants but do not affect electrical performance or pin compatibility.

Q: Can SMCJ130CE3/TR13 be used where SMCJ130C was specified?

A: SMCJ130CE3/TR13 is electrically compatible but with different clamping characteristics. It provides higher clamping voltage (231V vs. 219.45V) and lower peak pulse current (6.5A vs. 7.2A). Use only if the application circuit can tolerate the higher clamping voltage and lower current rating.

Q: What packaging options are available for these substitutes?

A: Most substitutes are available in Tape & Reel (TR) packaging for automated assembly. SMCJ130CA and SMLJ130CA-TP are available in bulk packaging. All maintain the DO-214AB (SMC) component package footprint for PCB compatibility.
