Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1N4752A-T is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Zener voltage: 33 V nominal with ±5% tolerance
• Maximum power dissipation: 1.3 W
• Reverse leakage current: 5 µA @ 25.1 V
• Forward voltage: 1.2 V @ 200 mA
• Operating temperature rating: 175°C

Mechanical & Environmental Compliance:

• Through-hole mounting configuration
• DO-41 / DO-204AL axial package
• Automotive grade qualification (AEC-Q101)
• ROHS3 compliance
• Moisture Sensitivity Level 1

Packaging Consideration: The 1N4752A-T is supplied in standard packaging format. The substitute 1N4752A-TR is supplied in cut tape (CT) packaging. Both parts share identical electrical characteristics and package geometry, with the difference limited to supply format.

Parameter Comparison

Engineering Selection Recommendations

The 1N4752A-TR is a direct functional equivalent to the 1N4752A-T. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical specifications, automotive qualification (AEC-Q101), and through-hole DO-41 package geometry.

Product Status Consideration: The 1N4752A-T is classified as obsolete, while the 1N4752A-TR maintains active product status. For new designs, ongoing production, or component replenishment, the 1N4752A-TR is the appropriate selection.

Compliance & Certification: Both parts meet ROHS3 compliance requirements and carry AEC-Q101 automotive qualification. Moisture Sensitivity Level 1 (unlimited) applies to both variants, indicating no moisture-related handling restrictions.

Impedance Specification: The 1N4752A-T specifies maximum impedance of 1000 Ohms, while the 1N4752A-TR specifies 45 Ohms. This difference reflects measurement or specification methodology variation between product generations. Both parts maintain identical voltage regulation characteristics and forward/reverse current specifications required for circuit operation.

Packaging Format: The primary distinction between these parts is supply format. The 1N4752A-T is supplied in standard packaging, while the 1N4752A-TR is supplied in cut tape (CT) format. This difference does not affect component performance or circuit compatibility.
