Part Overview
The CPDQR5V0UP is a unidirectional transient voltage suppressor (TVS) diode manufactured by Comchip Technology, designed for general-purpose overvoltage protection in surface-mount applications. This component features a 5V reverse standoff voltage with a 12.5V maximum clamping voltage and 2A peak pulse current rating in a compact 0402/SOD-923 package. The part is active in production with full RoHS3 compliance and unlimited moisture sensitivity rating.
Equivalent and substitute parts are identified when they maintain functional compatibility across critical electrical parameters including reverse standoff voltage, breakdown voltage, clamping voltage, and peak pulse current specifications, while accommodating variations in package form factors and thermal performance characteristics.

Substitute Part Grouping Explanation
Substitution eligibility for the CPDQR5V0UP is determined by strict alignment of the following critical electrical parameters:
- Reverse standoff voltage maintained at 5V maximum
- Breakdown voltage within the 6V to 6.4V range
- Clamping voltage tolerance between 10V and 12.5V
- Peak pulse current capability of 2A or greater at 8/20µs pulse width
- Unidirectional channel configuration (single channel)
- Surface-mount packaging compatible with automated assembly
Substitute parts may employ different physical package geometries (SOD-882, DFN1006-2, LLP1006-2L) provided they maintain electrical equivalence within these parameters. Operating temperature range extensions and automotive-grade qualifications represent performance enhancements rather than substitution barriers.

Engineering Selection Recommendations
All identified substitute parts maintain active production status with full RoHS3 compliance, ensuring long-term availability and regulatory alignment with the original CPDQR5V0UP.
PESD5V0L1UL,315 and VESD05A1B-HD1-GS08 provide direct electrical equivalence with clamping voltages of 12V and 11V respectively, matching the original 12.5V specification within acceptable engineering tolerance. Both parts support peak pulse currents of 3A and 3A, exceeding the 2A baseline requirement. PESD5V0L1UL,315 includes automotive-grade qualification (AEC-Q101) with extended operating temperature to 150°C.
SP3030-01ETG delivers equivalent 2A peak pulse current with a 10V typical clamping voltage and automotive qualification. This part is suitable for applications where clamping voltage tolerance permits operation at the lower end of the specified range.
PESD5V0S1UL,315 supports significantly higher peak pulse current (15A) and power dissipation (150W) with a 20V clamping voltage. This part functions as a substitute only in applications where the elevated clamping voltage does not compromise circuit protection requirements.
PESD5V0U1UL,315 provides the lowest capacitance (2pF) among substitutes with automotive qualification, suitable for high-frequency signal path applications where capacitive loading must be minimized.
Frequently Asked Questions (FAQ)
Q: Can PESD5V0S1UL,315 be used as a direct replacement for CPDQR5V0UP?
A: PESD5V0S1UL,315 maintains the required 5V reverse standoff voltage and exceeds peak pulse current requirements. However, its 20V clamping voltage is significantly higher than the original 12.5V specification. Substitution is valid only when circuit design permits operation at the elevated clamping voltage without compromising protected component ratings.
Q: What is the primary difference between PESD5V0L1UL,315 and VESD05A1B-HD1-GS08?
A: Both parts provide equivalent clamping performance at 12V and 11V respectively with 3A peak pulse current capability. PESD5V0L1UL,315 extends operating temperature to 150°C and includes automotive qualification. VESD05A1B-HD1-GS08 maintains the original -40°C to 125°C temperature range. Selection depends on thermal environment and automotive application requirements.
Q: Are package differences between 0402/SOD-923F and SOD-882/DFN1006-2 significant for substitution?
A: Package geometry differences require PCB layout modification and requalification of assembly processes. Electrical performance remains equivalent. Substitution is valid from an electrical standpoint but necessitates design review and manufacturing process updates.
Q: Why does PESD5V0U1UL,315 show missing clamping voltage and peak pulse current data?
A: The provided specifications for PESD5V0U1UL,315 do not include clamping voltage and peak pulse current values. This part maintains the required 5V reverse standoff voltage and automotive qualification. Complete datasheet review is necessary before selection for applications where these parameters are critical.
Q: Which substitute part offers the best high-frequency performance?
A: SP3030-01ETG provides the lowest capacitance at 0.5pF @ 1MHz, followed by PESD5V0U1UL,315 at 2pF. These parts are preferred for signal path protection where capacitive loading must be minimized. PESD5V0S1UL,315 exhibits the highest capacitance at 152pF and is suitable for power supply protection applications.
Q: Are all substitute parts suitable for general-purpose applications?
A: CPDQR5V0UP and VESD05A1B-HD1-GS08 are explicitly rated for general-purpose applications. Remaining substitutes do not specify application category in provided data. Selection for general-purpose use requires datasheet review to confirm suitability beyond the electrical parameter equivalence established in this reference.
