1N5635A Equivalent & Substitute Parts

Part Overview

The 1N5635A is a unidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose voltage clamping applications. This through-hole component operates across a temperature range of -65°C to 175°C and provides peak pulse power handling of 1500W. The part is currently in active production status with 1002 units available in bulk packaging. Alternative components may be required due to packaging preferences, supply chain considerations, or specific compliance requirements for end applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1N5635A is determined by electrical and mechanical compatibility within the following parameters:

Critical Electrical Parameters:

• Voltage - Reverse Standoff (Typ): 10.0V to 10.2V
• Voltage - Clamping (Max) @ Ipp: 16.7V to 17.0V
• Current - Peak Pulse (10/1000µs): 88A to 90A
• Power - Peak Pulse: 1500W minimum

Mechanical Compatibility:

• Mounting Type: Through Hole
• Package / Case: DO-13, DO-201AA, DO-27, or equivalent axial configurations

Functional Requirements:

• Type: Zener TVS Diode
• Unidirectional Channels: 1
• Applications: General Purpose

The LCE10A from Littelfuse meets these substitution criteria with equivalent electrical performance and compatible through-hole mounting.

Engineering Selection Recommendations

1N5635A Selection Criteria:

• Microchip Technology manufacturer designation
• RoHS non-compliant status
• Bulk packaging configuration
• Operating temperature minimum of -65°C required
• DO-13 package form factor specified

LCE10A Selection Criteria:

• Littelfuse manufacturer designation
• ROHS3 Compliant status
• Cut Tape (CT) packaging configuration
• Operating temperature minimum of -55°C acceptable
• DO-201AA / DO-27 package form factors available

Selection between these components depends on application-specific requirements: choose the 1N5635A for designs requiring the extended lower temperature range (-65°C minimum) or bulk packaging; select the LCE10A for applications requiring RoHS3 compliance or cut tape packaging formats.

Frequently Asked Questions (FAQ)

Q: Can the LCE10A directly replace the 1N5635A in existing circuit designs?

A: Yes, the LCE10A is electrically compatible with the 1N5635A. Both components share equivalent voltage clamping characteristics (16.7V to 17V), peak pulse current ratings (88A to 90A), and power dissipation (1500W). Physical board layout modifications may be required due to package differences (DO-13 versus DO-201AA/DO-27).

Q: What is the primary difference between these two TVS diodes?

A: The primary differences are manufacturer (Microchip versus Littelfuse), package configuration (DO-13 versus DO-201AA/DO-27), RoHS compliance status (non-compliant versus ROHS3 compliant), and minimum operating temperature (-65°C versus -55°C). Electrical performance is equivalent.

Q: Does the LCE10A require different PCB footprint design?

A: Yes. The 1N5635A uses a DO-13 package, while the LCE10A uses DO-201AA or DO-27 axial packages. These have different lead spacing and mounting hole requirements. PCB layout must be verified for compatibility with the selected package type.

Q: Are both components suitable for general-purpose transient voltage suppression?

A: Yes. Both the 1N5635A and LCE10A are rated for general-purpose applications and provide identical transient voltage suppression functionality across their specified operating ranges.

Q: What packaging format is available for each component?

A: The 1N5635A is supplied in bulk packaging. The LCE10A is supplied in cut tape (CT) packaging. Packaging selection may influence procurement quantities and handling procedures.

Q: Is RoHS compliance a factor in component selection?

A: RoHS compliance becomes relevant only if the end application or regulatory environment requires it. The 1N5635A is RoHS non-compliant, while the LCE10A is ROHS3 compliant. Verify application requirements before selection.
