CPDV5-5V0U-HF Equivalent & Substitute Parts

Part Overview

The CPDV5-5V0U-HF is a Transient Voltage Suppressor (TVS) diode manufactured by Comchip Technology, designed for general-purpose transient protection applications. This unidirectional 4-channel Zener diode operates with a 5V reverse standoff voltage and provides 10V maximum clamping at peak pulse current. The device is housed in a 5-TSSOP (SOT-353) surface mount package and is ROHS3 compliant with MSL 1 rating. As an active product with 2,367 units in stock, equivalent alternatives may be required for supply chain optimization, design flexibility, or application-specific performance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CPDV5-5V0U-HF is determined by the following critical parameters:

Primary Compatibility Criteria:

• Unidirectional channel configuration: 4 channels
• Package / Case: 5-TSSOP, SC-70-5, SOT-353 (surface mount)
• Voltage - Reverse Standoff (Typ): 5V
• Voltage - Breakdown (Min): 6.1V minimum
• Voltage - Clamping (Max) @ Ipp: 10V maximum
• Current - Peak Pulse (8/20µs): 8A minimum
• Power - Peak Pulse: 80W minimum
• Type: Zener diode
• RoHS Status: ROHS3 Compliant

Identified Substitute Parts:

1. CPDV5-5V0U (Comchip Technology) — Direct equivalent with identical electrical specifications and packaging
2. MSQA6V1W5T2G (onsemi) — Alternative with compatible package and general-purpose TVS application profile; note voltage and current parameters differ
3. NSQA6V8AW5T2G (onsemi) — Alternative with compatible package; voltage standoff matches at 5V; current and power ratings differ

Parameter Comparison

Engineering Selection Recommendations

CPDV5-5V0U (Direct Equivalent): This part is the primary substitute, offering identical electrical specifications, packaging, and compliance certifications. Both CPDV5-5V0U-HF and CPDV5-5V0U are manufactured by Comchip Technology with ROHS3 compliance and MSL 1 rating. The CPDV5-5V0U maintains 5V reverse standoff, 10V clamping voltage, and 8A peak pulse current. This substitution requires no circuit redesign.

MSQA6V1W5T2G (onsemi): This part shares the same package footprint and general-purpose TVS application classification. However, the reverse standoff voltage is 3V (versus 5V), which represents a significant electrical difference. The power dissipation capability is higher at 150W. This part is suitable only for applications where the lower voltage threshold is acceptable or beneficial.

NSQA6V8AW5T2G (onsemi): This part maintains the 5V reverse standoff voltage matching the original specification. The package is identical (5-TSSOP, SOT-353). However, the peak pulse current is reduced to 1.6A and power dissipation is 20W, both substantially lower than the original 8A and 80W. This part is suitable only for lower-current transient protection applications.

All substitute parts are ROHS3 compliant with MSL 1 rating and active product status.

Frequently Asked Questions (FAQ)

Q: Can CPDV5-5V0U directly replace CPDV5-5V0U-HF?

A: Yes. Both parts are manufactured by Comchip Technology with identical electrical specifications: 5V reverse standoff, 6.1V minimum breakdown, 10V maximum clamping, 8A peak pulse current, and 80W power dissipation. Both use the 5-TSSOP (SOT-353) package and are ROHS3 compliant with MSL 1 rating. No circuit modification is required.

Q: What is the key difference between MSQA6V1W5T2G and the original part?

A: The MSQA6V1W5T2G has a 3V reverse standoff voltage compared to the original 5V. This lower threshold means the device will trigger transient suppression at a lower voltage level. The clamping voltage and peak pulse current specifications are not provided for this part. Selection depends on whether your application requires 3V or 5V protection threshold.

Q: Can NSQA6V8AW5T2G be used in high-current transient protection circuits?

A: No. The NSQA6V8AW5T2G is rated for 1.6A peak pulse current and 20W power dissipation, compared to the original part's 8A and 80W. This part is suitable only for lower-current applications. Use this substitute only if your circuit's transient current requirements are 1.6A or below.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts use the 5-TSSOP (SC-70-5, SOT-353) surface mount package, ensuring mechanical and footprint compatibility. However, CPDV5-5V0U and MSQA6V1W5T2G are supplied in Tape & Reel (TR) format, while NSQA6V8AW5T2G is supplied in Cut Tape (CT) & Digi-Reel® format. Verify packaging requirements for your assembly process.

Q: Do all parts meet the same compliance standards?

A: Yes. CPDV5-5V0U-HF, CPDV5-5V0U, MSQA6V1W5T2G, and NSQA6V8AW5T2G are all ROHS3 compliant, REACH unaffected, and rated MSL 1 (Unlimited). All parts are classified as active products.
