Equivalent & Substitute Parts Reference for SMBG22A-E3/52

Part Overview

SMBG22A-E3/52 is an active Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. It features a 22V reverse standoff voltage, 35.5V maximum clamping voltage at 16.9A peak pulse, and a 600W peak pulse power rating in a DO-215AA (SMBG) surface mount package. This part is RoHS3 compliant and intended for general-purpose transient voltage protection applications. Alternative models may be required due to supply constraints, inventory allocation, or standardized component selection across platforms.

Key Parameters

Substitute Part Grouping Explanation

Substitution is strictly determined by matching the parameters: reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, peak pulse power, operating temperature range, package type, compliance status (RoHS, REACH), channel count, and application. Both SMBG22A-E3/52 and SMBJ22A-TR are unidirectional Zener TVS diodes in surface-mount SMB/SMBG-style packages, intended for general-purpose use, with identical electrical ratings (except for peak pulse current) and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Both SMBG22A-E3/52 and SMBJ22A-TR are classified as active, ROHS3 compliant, and REACH unaffected. Each device meets the specified regulatory requirements and supply chain controls designated by ECCN EAR99 and HTSUS 8541.10.0080. These attributes support compatibility for engineering selection based strictly on part status and compliance documentation.

Frequently Asked Questions (FAQ)

Q1: What parameters must be identical for a TVS diode to serve as a substitute?
A1: The reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, peak pulse power, operating temperature range, channel count, package type, and compliance status must match or be equivalent as specified for substitution.

Q2: Can SMBJ22A-TR replace SMBG22A-E3/52 in the same circuit?
A2: Based on provided parameters, both parts share identical electrical ratings and compliance status, supporting compatibility. The package styles are both SMB/SMBG format with surface-mount capabilities.

Q3: Are there regulatory compliance differences between the parts?
A3: Both SMBG22A-E3/52 and SMBJ22A-TR are ROHS3 compliant, REACH unaffected, ECCN EAR99, and have the same HTSUS code.

Q4: Do the package types impact direct substitution?
A4: Both parts are supplied in standard SMB-family surface-mount packages. Mechanical mounting compatibility must be confirmed based on actual package dimensions provided by the manufacturer.

Q5: How does peak pulse current affect substitute appropriateness?
A5: SMBJ22A-TR has a slightly higher peak pulse current rating (17.7A vs. 16.9A) with identical voltage and power parameters, maintaining substitution compatibility within specified limits.
