Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6SMB100A-E3/52 are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 85.5V
• Voltage - Breakdown (Min): 95V
• Voltage - Clamping (Max) @ Ipp: 137V (or higher)
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Unidirectional Channels: 1
• Type: Zener

Allowable Variations:

• Current - Peak Pulse (10/1000µs): 4.4A or higher
• Power - Peak Pulse: 600W or higher
• Operating Temperature: -55°C to -65°C minimum; 150°C or higher maximum
• RoHS Status: ROHS3 Compliant or equivalent
• Product Status: Active

Substitute parts meeting these criteria maintain functional and mechanical compatibility with the original P6SMB100A-E3/52 in circuit applications requiring 85.5V standoff protection with SMB surface mount packaging.

Frequently Asked Questions (FAQ)

Q: Can I substitute P6SMB100A-E3/52 with any of the listed parts?

A: Yes, all listed parts meet the critical electrical parameters (85.5V standoff, 95V breakdown minimum, 137V clamping maximum) and share the DO-214AA SMB surface mount package. Substitution is valid based on matching voltage ratings and package compatibility.

Q: What is the difference between SM6T100A and the other substitutes?

A: SM6T100A has a higher clamping voltage (178V) and significantly higher peak pulse current (22.5A at 8/20µs pulse width). This part provides enhanced transient suppression capability and is suitable for applications requiring greater energy dissipation.

Q: Which substitute has the widest operating temperature range?

A: Both SMBJP6KE100A-TP and 1KSMB100A support operating temperatures from -55°C to 175°C, providing the widest upper temperature limit among the substitutes.

Q: Is SZP6SMB100AT3G suitable for automotive applications?

A: Yes. SZP6SMB100AT3G carries automotive-grade qualification (AEC-Q101) and is specifically designed for automotive and high-reliability applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are RoHS compliant (ROHS3 or equivalent), meeting regulatory requirements for hazardous substance restrictions.

Q: What packaging options are available for the substitutes?

A: Eaton P6SMB100A is available in Cut Tape (CT) and Digi-Reel packaging. Other substitutes are available in Tape & Reel (TR) or Cut Tape packaging. All maintain the DO-214AA SMB surface mount form factor.

Q: Can I use 1KSMB100A as a direct replacement if my circuit requires higher power handling?

A: Yes. 1KSMB100A provides 1000W peak pulse power (versus 600W for the original), making it suitable for applications requiring higher transient energy dissipation while maintaining the same voltage protection characteristics.
