P4SMA130C Equivalent & Substitute Parts

Part Overview

The P4SMA130C 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 111V reverse standoff voltage with 187.95V maximum clamping voltage and 2.3A peak pulse current capability in a DO-214AC (SMA) package. The part is currently obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution for the P4SMA130C is determined by the following critical parameters:

Voltage - Reverse Standoff (Typ): 111V
Voltage - Clamping (Max) @ Ipp: 179V–187.95V range
Current - Peak Pulse (10/1000µs): 2.3A–2.8A range
Package / Case: DO-214AC, SMA
Mounting Type: Surface Mount
Type: Zener, Bidirectional

The three substitute parts listed maintain compatibility within these electrical and mechanical boundaries. All substitutes are active products with current manufacturing status, addressing the obsolescence of the original P4SMA130C.

Engineering Selection Recommendations

P4SMA130CA (Eaton - Electronics Division) is the primary recommended substitute. It maintains identical reverse standoff voltage (111V), peak pulse current (2.3A), and power dissipation (400W) specifications. The clamping voltage is 179V, within acceptable tolerance of the original 187.95V specification. This part is active in production with substantial inventory availability (22600 units). RoHS compliance is confirmed. The operating temperature range is -55°C to 150°C, which is narrower than the original at the lower end but suitable for most applications.

SMAJ100CE3/TR13 (Microchip Technology) offers an alternative with higher peak pulse current capability (2.8A) and increased power dissipation (500W). The reverse standoff voltage is 100V, which is 11V lower than the original specification. This part maintains ROHS3 compliance and the full -65°C to 150°C operating temperature range of the original. Selection of this part requires confirmation that the 100V standoff voltage is acceptable for the application.

SMAJP4KE130CA-TP (Micro Commercial Co) matches the P4SMA130CA in electrical specifications (111V standoff, 2.3A peak pulse, 400W power) and extends the upper operating temperature to 175°C. RoHS status is not specified for this part. Inventory is available at 1053 units.

Frequently Asked Questions (FAQ)

Q: Can P4SMA130CA directly replace P4SMA130C without circuit modification?

A: Yes. The P4SMA130CA maintains the same reverse standoff voltage (111V), peak pulse current (2.3A), and power dissipation (400W). The clamping voltage difference (179V vs. 187.95V) is within normal manufacturing tolerance for TVS diodes. Both use identical DO-214AC (SMA) packaging.

Q: Why does SMAJ100CE3/TR13 have a lower reverse standoff voltage?

A: The SMAJ100CE3/TR13 is specified at 100V reverse standoff versus 111V for the original. This 11V difference affects the trigger threshold for overvoltage protection. Use this substitute only if circuit analysis confirms that 100V standoff voltage is acceptable for your application requirements.

Q: Are all substitutes RoHS compliant?

A: P4SMA130CA and SMAJ100CE3/TR13 are confirmed RoHS compliant. SMAJP4KE130CA-TP does not specify RoHS status in the provided data. Verify RoHS compliance requirements with your procurement or quality department before selection.

Q: What is the difference between packaging options listed?

A: All substitute parts use DO-214AC (SMA) surface-mount packaging, identical to the original P4SMA130C. P4SMA130CA is supplied in Tape & Reel format; SMAJP4KE130CA-TP is supplied in Bulk. Tape & Reel packaging is standard for automated assembly processes.

Q: Which substitute has the best temperature performance?

A: SMAJP4KE130CA-TP extends the upper operating temperature to 175°C compared to 150°C for the original and other substitutes. The original P4SMA130C and SMAJ100CE3/TR13 both support -65°C minimum temperature, while P4SMA130CA and SMAJP4KE130CA-TP are rated to -55°C minimum.
