MASMLG8.0CA TVS Diode Equivalent & Substitute Parts

Part Overview

The MASMLG8.0CA is a transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose voltage clamping applications. This surface-mount component operates with an 8V reverse standoff voltage and provides 13.6V maximum clamping voltage at peak pulse current. The device is qualified to MIL-PRF-19500 military standards and maintains active product status. Substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MASMLG8.0CA are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic requires matching specifications in the following categories:

Electrical Parameters: Voltage - Reverse Standoff (8V), Voltage - Breakdown (8.89V minimum), Voltage - Clamping (13.6V maximum at Ipp), and Current - Peak Pulse (220.6A at 10/1000µs pulse duration) must be identical.

Thermal Parameters: Operating temperature range (-65°C to 150°C junction temperature) must be maintained.

Mechanical Parameters: Package type (DO-215AB, SMC Gull Wing), mounting type (Surface Mount), and supplier device package (SMLG) must be identical.

Compliance Parameters: Military grade classification and MIL-PRF-19500 qualification must be present.

Device Characteristics: Type (Zener), bidirectional channels (1), and applications (General Purpose) must match.

Parameter Comparison

Engineering Selection Recommendations

Both MASMLG8.0CA and MSMLG8.0CA are manufactured by Microchip Technology and carry identical electrical, thermal, and mechanical specifications. Both parts maintain active product status and are qualified to MIL-PRF-19500 military standards. Selection between these parts is based on inventory availability and procurement requirements rather than technical differentiation.

The MASMLG8.0CA currently maintains 1147 pieces in stock, while the MSMLG8.0CA maintains 797 pieces in stock. Both parts are supplied in bulk packaging and are suitable for direct substitution in applications requiring 8V reverse standoff voltage clamping with 220.6A peak pulse current handling capability.

Compliance considerations are identical for both parts: both are RoHS non-compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity level is 1 (unlimited) for both parts, indicating no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can MSMLG8.0CA be used as a direct replacement for MASMLG8.0CA?

A: Yes. Both parts are manufactured by Microchip Technology and share identical electrical specifications (8V reverse standoff, 13.6V clamping voltage, 220.6A peak pulse current), thermal operating range (-65°C to 150°C), mechanical package (DO-215AB SMLG), and military qualification (MIL-PRF-19500). Direct substitution is supported without circuit modification.

Q: Are there any differences in packaging or handling between these parts?

A: No. Both parts are supplied in bulk packaging with identical moisture sensitivity level (MSL 1 - Unlimited), indicating equivalent handling and storage requirements. Both use the same DO-215AB surface-mount package with SMC gull wing configuration.

Q: What is the significance of the base product number SMLG8.0?

A: The base product number SMLG8.0 identifies the core device design and electrical specifications. Both MASMLG8.0CA and MSMLG8.0CA share this base product number, confirming they are variants of the same fundamental TVS diode design with identical performance characteristics.

Q: Do both parts meet military qualification requirements?

A: Yes. Both MASMLG8.0CA and MSMLG8.0CA are military-grade components qualified to MIL-PRF-19500 standard. Both maintain active product status and are suitable for applications requiring military-grade transient voltage suppression.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by matching voltage ratings (8V reverse standoff, 8.89V minimum breakdown, 13.6V maximum clamping), current handling (220.6A peak pulse at 10/1000µs), power dissipation (3000W peak pulse), and operating temperature range (-65°C to 150°C). Both parts meet all these criteria identically.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts share identical compliance status: RoHS non-compliant, REACH unaffected, ECCN EAR99, and HTSUS 8541.10.0080. Regulatory and compliance considerations are equivalent for both parts.
