MASMBG10CAE3 Equivalent & Substitute Parts

Part Overview

The MASMBG10CAE3 is a Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection in surface-mount applications. This bidirectional Zener-type TVS diode operates with a 10V reverse standoff voltage and provides 17V maximum clamping voltage at peak pulse current. The device is qualified to MIL-PRF-19500 military standards and is currently in active production status. Finding equivalent or substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and maintain component availability across manufacturing cycles.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MASMBG10CAE3 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Voltage - Reverse Standoff (Typ): 10V
• Voltage - Breakdown (Min): 11.1V
• Voltage - Clamping (Max) @ Ipp: 17V
• Current - Peak Pulse (10/1000µs): 35.3A
• Power - Peak Pulse: 600W

Mechanical & Environmental Parameters:

• Package / Case: DO-215AA, SMB Gull Wing (SMBG)
• Mounting Type: Surface Mount
• Operating Temperature Range: -65°C to 150°C (TJ)

Compliance & Qualification:

• Grade: Military
• Qualification: MIL-PRF-19500
• Type: Zener, Bidirectional (1 channel)

The substitute part MASMBG10CA meets all specified electrical, mechanical, and compliance requirements and is therefore a direct equivalent for the MASMBG10CAE3.

Parameter Comparison

Engineering Selection Recommendations

The MASMBG10CA is a direct equivalent substitute for the MASMBG10CAE3. Both parts are manufactured by Microchip Technology and share identical electrical specifications, mechanical packaging, and military-grade qualifications under MIL-PRF-19500. Both devices maintain active production status and are available in bulk packaging.

Selection between these parts is based on inventory availability and supply chain requirements rather than technical differentiation. The MASMBG10CA currently has higher inventory availability (1065 pcs) compared to the MASMBG10CAE3 (714 pcs), making it suitable for applications requiring immediate component procurement or larger production volumes.

Both parts comply with identical regulatory classifications (RoHS non-compliant, REACH Unaffected, ECCN EAR99, HTSUS 8541.10.0080) and maintain the same moisture sensitivity level (MSL 1 - Unlimited), ensuring equivalent handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can MASMBG10CA be used as a direct replacement for MASMBG10CAE3?

A: Yes. The MASMBG10CA is a direct equivalent substitute. All electrical parameters, mechanical specifications, military qualifications, and compliance certifications are identical between the two parts.

Q: Are there any differences in the package or mounting requirements?

A: No. Both parts use the identical DO-215AA SMB Gull Wing (SMBG) surface-mount package. PCB footprints, solder pad layouts, and mounting procedures are identical.

Q: Do both parts meet the same military qualification standards?

A: Yes. Both MASMBG10CAE3 and MASMBG10CA are qualified to MIL-PRF-19500 and carry military-grade classification.

Q: What is the difference between these two part numbers?

A: The primary difference is the suffix designation (CAE3 versus CA). Both parts are manufactured by Microchip Technology and share the same base product number (SMBG10). The suffix variation does not indicate functional or electrical differences.

Q: Are there any RoHS or environmental compliance differences?

A: No. Both parts carry identical RoHS non-compliant status, REACH Unaffected classification, and EAR99 export control designation.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and supply chain lead times. The MASMBG10CA currently has higher stock levels.

Q: Do these parts have different operating temperature ranges?

A: No. Both parts operate across the identical temperature range of -65°C to 150°C (TJ).

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The MASMBG10CA can be substituted into any design currently using the MASMBG10CAE3 without circuit modifications or re-qualification.
