P6SMB11C Equivalent & Substitute Parts Reference

Part Overview

The Littelfuse Inc. P6SMB11C is a bidirectional Zener-type Transient Voltage Suppressor (TVS) diode designed for general-purpose applications. This device provides overvoltage protection with a reverse standoff voltage of 9.4V and a peak pulse power rating of 600W. The P6SMB11C is supplied in a DO-214AA (SMBJ) surface mount package and is part of the P6SMB series. As the P6SMB11C part status is listed as obsolete, identifying equivalent or substitute models is necessary for ongoing designs, repairs, and inventory management.

Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on the following key parameters: unidirectional/bidirectional configuration, reverse standoff voltage, breakdown voltage, maximum clamping voltage at peak pulse current, peak pulse current, peak pulse power rating, mounting type, package form, operating temperature range, and regulatory compliance. Only parts that match in package, electrical characteristics, and compliance can be considered direct substitutes in the Transient Voltage Suppressors (TVS) category.

Parameter Comparison

Engineering Selection Recommendations

Selection between P6SMB11C and substitute models P6SMB11CA (Eaton - Electronics Division), SM6T12CA (STMicroelectronics), and SMBJP6KE11CA-TP (Micro Commercial Co) is enabled by part status, RoHS compliance, and Moisture Sensitivity Level (MSL). P6SMB11C is listed as obsolete, while the substitute parts are marked as active. RoHS compliance and MSL 1 (Unlimited) are maintained across all substitute components.

Frequently Asked Questions (FAQ)

Q1: What parameters are critical for substituting a TVS diode in the P6SMB series?
A: The critical parameters for substitution are bidirectional/unidirectional type, reverse standoff voltage, breakdown voltage, clamping voltage at peak pulse, peak pulse current, peak pulse power, package type, mounting style, operating temperature, and compliance certifications.

Q2: Are the substitute parts mechanically compatible with the original P6SMB11C?
A: All substitute parts listed use the DO-214AA (SMB) surface-mount package, ensuring mechanical compatibility.

Q3: Is the electrical performance equivalent between the P6SMB11C and the suggested substitutes?
A: The substitute TVS diodes provide matching or closely aligned reverse standoff voltage, peak pulse power, peak pulse current, and comparable breakdown and clamping voltage values.

Q4: Are there any differences in compliance or regulatory status among these parts?
A: All substitutes and the P6SMB11C are RoHS compliant and rated MSL 1 (Unlimited).

Q5: Does replacing with an active substitute affect mounting or assembly procedures?
A: No changes are necessary for mounting or assembly, as all listed substitutes use the DO-214AA (SMB) surface mount package type.
