P6SMB11A-M3/52 Equivalent & Substitute Parts

Part Overview

The P6SMB11A-M3/52 is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates in the DO-214AA (SMB) package and provides transient overvoltage protection for general-purpose applications. The part is Active status and ROHS3 compliant. Equivalent and substitute parts are identified based on matching electrical characteristics and mechanical compatibility within the TVS diode category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P6SMB11A-M3/52 is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 9.4V
• Voltage - Breakdown (Min): 10.5V
• Voltage - Clamping (Max) @ Ipp: 15.6V
• Package / Case: DO-214AA, SMB (surface mount compatibility)
• Unidirectional Channels: 1
• Type: Zener

All identified substitute parts maintain these core electrical specifications and package compatibility. Variations in peak pulse current (38.5A to 64.1A) and power dissipation (600W to 1000W) represent enhanced performance characteristics that do not prevent substitution. Operating temperature ranges and packaging formats (Tape & Box vs. Tape & Reel) are secondary considerations that do not affect electrical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and comply with RoHS regulations, ensuring long-term availability and environmental compliance. The P6SMB11A-M3/52 (Vishay) and P6SMB11A (Eaton) are functionally equivalent with identical voltage and power specifications. The 1KSMB11A (Taiwan Semiconductor) offers enhanced peak pulse current (64.1A) and power dissipation (1000W), providing additional margin for transient protection. The SMBJP6KE11A-TP (Micro Commercial Co) matches the original specifications with extended operating temperature range to 175°C. Selection among these parts depends on application requirements for current handling capacity, thermal performance, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the 1KSMB11A replace the P6SMB11A-M3/52 in my circuit?

A: Yes. The 1KSMB11A maintains identical voltage specifications (9.4V standoff, 15.6V clamping) and package compatibility (DO-214AA, SMB). The higher peak pulse current (64.1A vs. 38.5A) and power rating (1000W vs. 600W) represent enhanced performance characteristics that do not prevent substitution.

Q: What is the difference between Tape & Box and Tape & Reel packaging?

A: Tape & Box (TB) and Tape & Reel (TR) are packaging and delivery formats that do not affect component electrical performance or mechanical compatibility. Selection depends on manufacturing process requirements and inventory management practices.

Q: Are all substitute parts ROHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant or RoHS compliant, meeting environmental and regulatory requirements.

Q: Does operating temperature range affect substitution eligibility?

A: Operating temperature range does not prevent substitution. The P6SMB11A-M3/52 operates from -65°C to 150°C. Substitute parts with extended ranges (-55°C to 175°C) provide additional thermal margin but are electrically interchangeable across the original temperature specification.

Q: Can I use the SMBJP6KE11A-TP as a direct replacement?

A: Yes. The SMBJP6KE11A-TP matches all critical electrical parameters and package specifications. The extended operating temperature range to 175°C provides additional design flexibility.
