SM16LC24C/TR13 Equivalent & Substitute Parts

Part Overview

The SM16LC24C/TR13 is an 8-channel bidirectional Zener-type transient voltage suppressor (TVS) diode manufactured by Microchip Technology. This surface-mount component operates with a 24V reverse standoff voltage and provides 55V maximum clamping voltage at peak pulse current. The device is designed for general-purpose transient protection applications and is currently in active production status. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and application-specific requirements where alternative specifications remain within acceptable operational parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SM16LC24C/TR13 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Bidirectional channels: 8 channels
• Voltage - Reverse Standoff: 24V nominal
• Voltage - Breakdown (Min): 26.7V
• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

Allowable Variation Parameters:

• Voltage - Clamping (Max) @ Ipp: Substitute parts must not exceed the original specification to ensure protection integrity
• Current - Peak Pulse: Substitute parts may operate at reduced current ratings if application requirements permit
• Operating Temperature Range: Substitute parts must support the minimum required operating range for the application
• Power - Peak Pulse: Maintained at 300W across substitute options
• Capacitance @ Frequency: Consistent at 25pF @ 1MHz

The S16LCC24-8 manufactured by SMC Diode Solutions meets all mandatory matching parameters and qualifies as a direct substitute within the specified electrical and mechanical constraints.

Engineering Selection Recommendations

SM16LC24C/TR13 (Microchip Technology):

• Primary selection for applications requiring 5A peak pulse current capability
• Suitable for general-purpose transient protection with higher energy dissipation requirements
• Operating temperature range extends to 150°C, supporting high-temperature environments
• RoHS non-compliant status requires verification against project compliance requirements
• Active product status ensures continued availability and supply chain stability

S16LCC24-8 (SMC Diode Solutions):

• Suitable for applications with peak pulse current requirements of 1A or lower
• Provides lower clamping voltage (43V vs. 55V), resulting in tighter transient suppression
• ROHS3 compliance supports regulatory requirements in restricted substance applications
• Operating temperature range limited to 125°C; verify compatibility with application thermal requirements
• Automotive-grade qualification indicates suitability for automotive and industrial environments
• Active product status ensures continued availability

Selection Criteria:

• Choose SM16LC24C/TR13 when application requires 5A peak pulse current handling or 55V clamping voltage specification
• Choose S16LCC24-8 when application operates within 1A peak pulse current limits, requires ROHS3 compliance, and operates below 125°C junction temperature
• Verify package footprint compatibility with PCB design; both parts use identical 16-SOIC packaging
• Confirm regulatory compliance requirements before final selection

Frequently Asked Questions (FAQ)

Q: Can the S16LCC24-8 directly replace the SM16LC24C/TR13 in all applications?

A: The S16LCC24-8 qualifies as a substitute only when application peak pulse current requirements do not exceed 1A and maximum clamping voltage of 43V is acceptable. Applications requiring the full 5A peak pulse current capability or 55V clamping voltage must use the SM16LC24C/TR13.

Q: What is the significance of the different clamping voltages (55V vs. 43V)?

A: Clamping voltage determines the maximum voltage level the TVS diode allows across the protected circuit during a transient event. The SM16LC24C/TR13 clamps at 55V maximum, while the S16LCC24-8 clamps at 43V maximum. Lower clamping voltage provides tighter protection but requires verification that the protected circuit can tolerate this lower voltage level.

Q: Are the packages physically identical?

A: Both parts use the 16-SOIC package with 0.154" (3.90mm) width. PCB footprints are identical, and parts are mechanically interchangeable from a mounting perspective.

Q: What does ROHS3 compliance mean for the S16LCC24-8?

A: ROHS3 compliance indicates the S16LCC24-8 meets Restriction of Hazardous Substances Directive requirements, restricting the use of specific hazardous materials. The SM16LC24C/TR13 is RoHS non-compliant and does not meet these restrictions. Selection depends on project regulatory requirements.

Q: How do the operating temperature ranges differ?

A: The SM16LC24C/TR13 operates from -55°C to 150°C junction temperature, while the S16LCC24-8 operates from -55°C to 125°C. Applications requiring operation above 125°C must use the SM16LC24C/TR13.

Q: What is the difference between the packaging formats (Cut Tape vs. Tape & Reel)?

A: Cut Tape (CT) packaging supplies individual components cut from the reel, suitable for small-quantity orders. Tape & Reel (TR) packaging supplies components on continuous reel format, optimized for high-volume automated assembly. Both formats contain identical components; packaging format selection depends on procurement volume and assembly process requirements.

Q: Can I use the S16LCC24-8 in a high-current transient protection circuit?

A: No. The S16LCC24-8 is rated for 1A peak pulse current, while the SM16LC24C/TR13 is rated for 5A. Using the S16LCC24-8 in applications exceeding 1A peak pulse current will result in device failure and loss of transient protection.

Q: What is the significance of the automotive-grade designation for the S16LCC24-8?

A: Automotive-grade qualification indicates the S16LCC24-8 meets automotive industry reliability and quality standards. This designation supports use in automotive and industrial applications with stringent quality requirements.
