SM1624C/TR13 Equivalent & Substitute Parts

Part Overview

The SM1624C/TR13 is an active Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology. This bidirectional 8-channel Zener diode is designed for general-purpose transient voltage suppression applications in surface-mount configurations. The device features a 24V reverse standoff voltage with a 55V maximum clamping voltage and handles peak pulse currents of 5A (8/20µs). The SM1624C/TR13 is supplied in Tape & Reel packaging format and maintains RoHS non-compliant status with unlimited moisture sensitivity rating. Substitute parts are identified to address packaging availability, inventory requirements, or specific application constraints while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SM1624C/TR13 are identified based on strict electrical and mechanical parameter matching. The primary substitution criterion is equivalence across the following parameters:

• Voltage - Reverse Standoff (Typ): 24V
• Voltage - Breakdown (Min): 26.7V
• Voltage - Clamping (Max) @ Ipp: 55V
• Current - Peak Pulse (10/1000µs): 5A (8/20µs)
• Power - Peak Pulse: 300W
• Bidirectional Channels: 8
• Operating Temperature Range: -55°C to 150°C
• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

The SM16LC24C/TR13 meets all electrical specifications and mechanical requirements for direct substitution. The primary difference between the main part and its substitute is the packaging format: the SM1624C/TR13 is supplied in Tape & Reel (TR) format, while the SM16LC24C/TR13 is supplied in Cut Tape (CT) format. Both parts share identical electrical performance characteristics and are manufactured by Microchip Technology with active product status.

Parameter Comparison

Engineering Selection Recommendations

The SM16LC24C/TR13 is a direct electrical and mechanical substitute for the SM1624C/TR13. Both parts are manufactured by Microchip Technology with active product status and identical compliance certifications (RoHS non-compliant, REACH Unaffected, EAR99 classification). The parts share equivalent electrical performance across all critical parameters: 24V reverse standoff voltage, 26.7V minimum breakdown voltage, 55V maximum clamping voltage, and 5A peak pulse current handling capability.

Selection between these parts is determined by packaging requirements. The SM1624C/TR13 is supplied in Tape & Reel format, suitable for high-volume automated assembly operations. The SM16LC24C/TR13 is supplied in Cut Tape format, appropriate for lower-volume applications or manual assembly processes. Both packaging formats are compatible with standard surface-mount assembly equipment and processes.

The capacitance difference (137pF versus 25pF at 1MHz) reflects manufacturing variations within the same device family and does not affect substitution eligibility for general-purpose transient voltage suppression applications.

Frequently Asked Questions (FAQ)

Q: Can the SM16LC24C/TR13 be used as a direct replacement for the SM1624C/TR13?

A: Yes. The SM16LC24C/TR13 is electrically and mechanically equivalent to the SM1624C/TR13. Both parts feature identical voltage ratings (24V reverse standoff, 55V clamping), current handling (5A peak pulse), and package specifications (16-SOIC surface mount). The primary difference is packaging format: Tape & Reel versus Cut Tape.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for high-speed automated assembly lines. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths, suitable for lower-volume production or manual assembly. Both formats use identical component specifications and 16-SOIC package dimensions.

Q: Are there any electrical performance differences between these parts?

A: No electrical performance differences exist for transient voltage suppression applications. Both parts meet identical voltage and current specifications. The capacitance values (137pF and 25pF at 1MHz) represent normal manufacturing variation within the same device family and do not affect suppression performance in general-purpose applications.

Q: Do both parts have the same compliance certifications?

A: Yes. Both the SM1624C/TR13 and SM16LC24C/TR13 share identical compliance status: RoHS non-compliant, REACH Unaffected, EAR99 export classification, and HTSUS code 8541.10.0080. Both parts maintain unlimited moisture sensitivity rating (MSL 1).

Q: Which part should be selected for new designs?

A: Selection depends on production volume and assembly method. For high-volume automated assembly, the SM1624C/TR13 (Tape & Reel) is standard. For lower-volume or manual assembly processes, the SM16LC24C/TR13 (Cut Tape) is appropriate. Both parts are active products with equivalent electrical performance.

Q: Are these parts suitable for power line protection applications?

A: No. Both parts are designated for general-purpose transient voltage suppression and are not rated for power line protection applications.
