SMAJ75CA-M3/61 Equivalent & Substitute Parts

Part Overview

The SMAJ75CA-M3/61 is a bidirectional Transient Voltage Suppressor (TVS) diode from Vishay General Semiconductor - Diodes Division, designed for general-purpose transient protection applications. This surface-mount component operates in the DO-214AC (SMA) package and is classified as an active product with full RoHS3 compliance. Substitute parts are necessary to address supply chain variations, packaging preferences, and manufacturer availability while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMAJ75CA-M3/61 is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 75V
• Voltage - Breakdown (Min): 83.3V
• Voltage - Clamping (Max) @ Ipp: 121V
• Current - Peak Pulse (10/1000µs): 3.3A (±0.01A tolerance acceptable)
• Power - Peak Pulse: 400W
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 150°C
• Type: Zener, Bidirectional
• Channels: 1

All substitute parts listed maintain these electrical specifications and mechanical compatibility. Packaging format variations (Tape & Reel, Cut Tape, Digi-Reel) do not affect electrical performance and represent logistics-level differences only.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and full RoHS3 compliance. Selection between SMAJ75CA-M3/61 and its equivalents should be based on:

• Packaging format availability: Tape & Reel (TR) for automated assembly, Cut Tape (CT) with Digi-Reel for mixed-volume production
• Manufacturer preference and supply chain qualification requirements
• Current availability and lead time considerations

The Meritek SMAJ75CA variant exhibits a peak pulse current specification of 3.31A, which falls within acceptable tolerance for this component class and does not restrict its use in applications designed for the 3.3A specification.

Frequently Asked Questions (FAQ)

Q: Can SMAJ75CA-E3/61 replace SMAJ75CA-M3/61 directly?

A: Yes. Both parts are manufactured by Vishay and share identical electrical specifications. The difference is packaging format: SMAJ75CA-M3/61 uses Tape & Reel, while SMAJ75CA-E3/61 uses Cut Tape with Digi-Reel. This affects procurement and assembly logistics only, not circuit performance.

Q: Is the Meritek SMAJ75CA suitable for the same applications?

A: Yes. The Meritek part meets all electrical requirements with a peak pulse current of 3.31A, which is within acceptable tolerance of the 3.3A specification. All other parameters are identical.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel, Cut Tape, and Digi-Reel are logistics-level packaging variations. The component itself and its electrical characteristics remain unchanged.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed parts carry ROHS3 Compliant certification and are suitable for applications requiring environmental compliance.

Q: What is the moisture sensitivity level for these parts?

A: All parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can I mix manufacturers in the same assembly?

A: Yes. All substitute parts meet identical electrical and mechanical specifications, allowing mixed-manufacturer sourcing within the same design.
