P6SMB130C Equivalent & Substitute Parts

Part Overview

The P6SMB130C is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose voltage clamping applications. This bidirectional Zener diode operates with a reverse standoff voltage of 111V and provides peak pulse current handling of 3.4A at a clamping voltage of 187.95V. The part is currently listed as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6SMB130C is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - Reverse Standoff (Typ): 111V (allows ±10% tolerance range)
• Voltage - Clamping (Max) @ Ipp: 179V–187.95V range
• Current - Peak Pulse (10/1000µs): 3.4A minimum
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB (surface mount compatibility)
• Bidirectional Channels: 1
• Type: Zener

Substitute parts must maintain electrical performance within these parameters to ensure functional equivalence in transient voltage suppression applications. Parts with lower clamping voltages or reduced peak pulse current ratings do not qualify as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Recommended):

P6SMB130CA (Eaton - Electronics Division) and P6SMB130CA-E3/5B (Vishay General Semiconductor) are the preferred substitutes. Both maintain the 111V reverse standoff voltage and 3.4A peak pulse current specifications. P6SMB130CA-E3/5B offers extended operating temperature range (-65°C to 150°C) and ROHS3 compliance. SMBJP6KE130CA-TP (Micro Commercial Co) provides the widest operating temperature range (-55°C to 175°C) while maintaining all critical electrical parameters.

Secondary Substitute:

SMBJ100CE3/TR13 (Microchip Technology) operates with a reduced reverse standoff voltage of 100V, making it suitable only for applications where the lower voltage rating is acceptable. This part maintains 3.4A peak pulse current and 600W power dissipation.

Alternative Substitute:

TVP06B131CA-G (Comchip Technology) provides equivalent performance with a marginally reduced peak pulse current of 3.35A. This part is suitable for applications with less stringent current requirements.

All substitute parts maintain DO-214AA/SMB package compatibility, ROHS3 compliance, and MSL 1 moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can I use SMBJ100CE3/TR13 as a direct replacement for P6SMB130C?

A: SMBJ100CE3/TR13 has a reverse standoff voltage of 100V compared to the P6SMB130C's 111V. While it maintains the same peak pulse current (3.4A) and clamping voltage (179V), the lower standoff voltage may affect circuit protection thresholds. Use only if your application tolerates a 100V standoff specification.

Q: What is the difference between the clamping voltages of P6SMB130C (187.95V) and the substitute parts (179V)?

A: The P6SMB130C has a higher maximum clamping voltage of 187.95V, while most substitutes clamp at 179V. This 8.95V difference represents improved voltage suppression performance in the substitute parts. Both values fall within acceptable transient voltage suppression ranges for general-purpose applications.

Q: Are all substitute parts available in the same DO-214AA/SMB package?

A: Yes. All listed substitute parts use the DO-214AA (SMB) surface mount package, ensuring mechanical and electrical compatibility with existing PCB layouts designed for the P6SMB130C.

Q: Which substitute offers the best temperature performance?

A: SMBJP6KE130CA-TP (Micro Commercial Co) provides the widest operating temperature range of -55°C to 175°C, compared to the P6SMB130C's -55°C to 150°C range. This extended upper temperature limit may be beneficial for high-temperature applications.

Q: Are all substitutes RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, matching the compliance status of the P6SMB130C. All parts also maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the peak pulse current difference between P6SMB130C and TVP06B131CA-G?

A: The P6SMB130C handles 3.4A peak pulse current, while TVP06B131CA-G handles 3.35A. This 0.05A difference is negligible for most applications and does not affect functional equivalence in standard transient voltage suppression circuits.
