CM6100 Transient Voltage Suppressor - Equivalent & Substitute Parts

Part Overview

The CM6100 is a steering-type transient voltage suppressor (TVS) diode manufactured by onsemi, designed for general-purpose power line protection applications. It features a 3V reverse standoff voltage, 9.8V typical clamping voltage, and 1A peak pulse current rating in a compact 4-WLCSP surface mount package. The CM6100 is classified as obsolete, making identification of functionally equivalent substitute components necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CM6100 is determined by the following critical electrical and mechanical parameters:

• Reverse standoff voltage tolerance (3V nominal)
• Breakdown voltage range (minimum 6V)
• Clamping voltage performance (9.8V typical)
• Peak pulse current capability (1A at 8/20µs)
• Package form factor (4-WLCSP surface mount)
• Steering diode topology (Rail to Rail configuration)
• Unidirectional channel count (2 channels)

The IP4369CX4YL from NXP Semiconductors shares the same package footprint (4-WLCSP) and steering diode architecture. However, critical electrical parameter differences exist that affect direct substitution feasibility.

Parameter Comparison

Engineering Selection Recommendations

Both the CM6100 and IP4369CX4YL are classified as obsolete products. The IP4369CX4YL presents significant electrical parameter deviations from the CM6100:

The IP4369CX4YL exhibits a higher reverse standoff voltage (5.5V max versus 3V typ), substantially lower clamping voltage (3V typ versus 9.8V typ), and higher peak pulse current capability (5A versus 1A). The IP4369CX4YL also provides four unidirectional channels compared to the CM6100's two channels, and features a different package designation (4-XFBGA versus 4-UFBGA).

These electrical differences indicate the IP4369CX4YL is not a direct functional equivalent for applications requiring the CM6100's specific voltage and current characteristics. Selection of either part requires verification that the application's voltage clamping and current handling requirements align with the chosen device's specifications.

Both components carry EAR99 export classification. The IP4369CX4YL is RoHS non-compliant, while the CM6100's RoHS status is not specified in available documentation.

Frequently Asked Questions (FAQ)

Q: Can the IP4369CX4YL directly replace the CM6100 in existing designs?

A: No. The IP4369CX4YL has significantly different electrical characteristics, including higher reverse standoff voltage (5.5V max vs. 3V typ), lower clamping voltage (3V typ vs. 9.8V typ), and higher peak pulse current (5A vs. 1A). Direct substitution is not recommended without circuit redesign and validation.

Q: What are the primary differences between these two TVS diodes?

A: The CM6100 is optimized for lower voltage applications with higher clamping voltage performance, while the IP4369CX4YL is designed for higher voltage standoff with greater current handling. The IP4369CX4YL also provides four protection channels versus the CM6100's two channels.

Q: Are the package footprints compatible?

A: Both devices use 4-WLCSP surface mount packages, but with different designations (4-UFBGA for CM6100 and 4-XFBGA for IP4369CX4YL) and slightly different physical dimensions (0.8x0.8mm versus 0.76x0.76mm). Physical compatibility should be verified with PCB layout requirements.

Q: What is the operating temperature range difference?

A: The CM6100 operates from -40°C to 85°C, while the IP4369CX4YL operates from -30°C to 85°C. Applications requiring operation below -30°C cannot use the IP4369CX4YL.

Q: Why are both products classified as obsolete?

A: Both the CM6100 and IP4369CX4YL are end-of-life products. For new designs, current-generation TVS diode alternatives from active product lines should be evaluated based on the same electrical parameter criteria outlined in this document.
