SMBG48C-E3/52 Equivalent & Substitute Parts

Part Overview

The SMBG48C-E3/52 is a transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division, designed for general-purpose overvoltage protection applications. This bidirectional Zener diode operates with a 48V reverse standoff voltage and provides peak pulse current handling of 7A with a maximum clamping voltage of 85.5V at peak pulse current.

The SMBG48C-E3/52 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBG48C-E3/52 is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 48V
• Voltage - Breakdown (Min): 53.3V
• Package / Case: DO-215AA, SMB Gull Wing
• Mounting Type: Surface Mount
• Bidirectional Channels: 1
• Series: TransZorb®

The SMBG48CA-E3/52 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. While the clamping voltage and peak pulse current differ slightly, these variations remain within acceptable tolerance ranges for general-purpose TVS diode applications and do not compromise functional compatibility in the specified application context.

Parameter Comparison

Engineering Selection Recommendations

The SMBG48CA-E3/52 is the primary substitute for the obsolete SMBG48C-E3/52. The substitute part maintains identical reverse standoff voltage, breakdown voltage, operating temperature range, package configuration, and compliance certifications. Both components are ROHS3 compliant with MSL rating of 1 (Unlimited), ensuring equivalent environmental and regulatory suitability.

The SMBG48CA-E3/52 carries Active product status, providing assured long-term availability and supply chain continuity compared to the obsolete SMBG48C-E3/52. The substitute part demonstrates improved peak pulse current capability (7.8A versus 7A) and lower maximum clamping voltage (77.4V versus 85.5V), characteristics that enhance performance margins in general-purpose protection applications.

Frequently Asked Questions (FAQ)

Q: Can the SMBG48CA-E3/52 directly replace the SMBG48C-E3/52 in existing designs?

A: Yes. Both components share identical reverse standoff voltage (48V), breakdown voltage (53.3V minimum), package configuration (DO-215AA SMB Gull Wing), and operating temperature range (-55°C to 150°C). The electrical parameter variations fall within acceptable substitution tolerances for general-purpose TVS applications.

Q: What are the key differences between these two parts?

A: The SMBG48CA-E3/52 provides higher peak pulse current (7.8A versus 7A) and lower maximum clamping voltage (77.4V versus 85.5V). The substitute part is Active status versus Obsolete, ensuring continued availability.

Q: Are there packaging differences between the SMBG48C-E3/52 and SMBG48CA-E3/52?

A: Both components use identical DO-215AA SMB Gull Wing surface mount packaging. No PCB layout modifications are required for substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SMBG48C-E3/52 and SMBG48CA-E3/52 are ROHS3 compliant with MSL rating of 1 (Unlimited), meeting equivalent environmental and regulatory requirements.

Q: Why is the SMBG48C-E3/52 classified as obsolete?

A: The SMBG48C-E3/52 has reached end-of-life status. The SMBG48CA-E3/52 represents the current active equivalent within the TransZorb® series, providing continued support for 48V TVS diode applications.
