VESD05-02V-GS08 Equivalent & Substitute Parts

Part Overview

The VESD05-02V-GS08 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This component is rated for 5V reverse standoff voltage with a 20V maximum clamping voltage and 6A peak pulse current (8/20µs). The device is packaged in SOD-523 surface mount form factor and is classified as obsolete. Due to its obsolete status, equivalent substitute parts with comparable electrical and mechanical specifications are necessary for ongoing design support and production continuity.

Engineering Selection Recommendations

Primary Substitutes (Recommended for Direct Replacement):

For applications requiring the closest electrical match to VESD05-02V-GS08 with SOD-523 package compatibility, the following parts are recommended based on active product status and compliance:

ESD5V0D5-TP (Micro Commercial Co): Matches 5V standoff voltage, 18.6V clamping voltage, and SOD-523 package. Operating temperature range extends to -55°C ~ 150°C. Active product status with full RoHS3 compliance.
ESD5Z5.0T1G and ESD5Z5.0T5G (onsemi): Both provide 5V standoff voltage, 18.6V clamping voltage, and SOD-523 package. Extended operating temperature to -55°C ~ 150°C. Active product status with high inventory availability and RoHS3 compliance.
CPDH5V0U (Comchip Technology): Maintains 5V standoff voltage and SOD-523 package with enhanced peak pulse current rating of 16A. Lower clamping voltage of 12.5V. Active product status with RoHS3 compliance and substantial inventory.

Secondary Substitutes (Alternative Voltage Ratings):

For applications where voltage rating flexibility exists, Nexperia PESD series parts (PESD12VS1UB,115, PESD15VS1UB,115, PESD24VS1UB,115) offer automotive-grade qualification (AEC-Q100) with SOD-523 package compatibility. These parts are suitable only if circuit design permits higher standoff voltages.

Package Alternative:

CPDF5V0 (Comchip Technology) provides 5V standoff voltage with 15V clamping voltage in 1005/SOD-323F package. This option is applicable only if PCB layout accommodates the alternative package footprint.

Frequently Asked Questions (FAQ)

Q: Can CPDH5V0U replace VESD05-02V-GS08 in all applications?

A: CPDH5V0U shares the same 5V standoff voltage and SOD-523 package as VESD05-02V-GS08. The primary difference is lower clamping voltage (12.5V vs. 20V) and higher peak pulse current (16A vs. 6A). Substitution is valid only if the circuit design tolerates the lower clamping voltage specification.

Q: What is the difference between ESD5Z5.0T1G and ESD5Z5.0T5G?

A: Both parts are electrically identical with 5V standoff voltage, 18.6V clamping voltage, and 9.4A peak pulse current in SOD-523 package. The difference is in packaging format: T1G uses Cut Tape & Digi-Reel, while T5G uses the same format with different reel configuration. Selection depends on procurement and assembly requirements.

Q: Why are PESD12VS1UB,115, PESD15VS1UB,115, and PESD24VS1UB,115 listed as substitutes if they have different voltage ratings?

A: These parts are listed as available alternatives within the TVS diode category with SOD-523 package compatibility. However, they are not direct functional replacements due to different standoff voltages (12V, 15V, and 24V respectively). Use only if circuit design explicitly requires these higher voltage ratings.

Q: Is CPDF5V0 a suitable replacement for VESD05-02V-GS08?

A: CPDF5V0 maintains the 5V standoff voltage specification but uses a different package (1005/SOD-323F instead of SOD-523). This substitution requires PCB redesign to accommodate the alternative footprint. Electrical performance differs with 15V clamping voltage and 5A peak pulse current.

Q: What compliance certifications apply to these substitute parts?

A: All listed substitute parts maintain RoHS3 compliance and REACH unaffected status, matching the original VESD05-02V-GS08. Nexperia parts (PESD series) carry automotive-grade qualification (AEC-Q100 or AEC-Q101) for applications requiring automotive standards.

Q: How do I determine which substitute is best for my application?

A: Verify that the substitute part meets three critical requirements: (1) matching or exceeding the required clamping voltage, (2) matching or exceeding the required peak pulse current, and (3) compatible package footprint. Cross-reference these parameters against your circuit protection requirements before final selection.
