V30D45CHM3_A/I Equivalent & Substitute Parts

Part Overview

The V30D45CHM3_A/I is a Schottky diode array manufactured by Vishay General Semiconductor - Diodes Division. This component features a 1 Pair Common Cathode configuration rated for 45 V DC reverse voltage and 15 A average rectified current per diode. The device is housed in a TO-263-3 D2PAK surface mount package with automotive-grade qualification (AEC-Q101) and is currently in active production status.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs while maintaining identical functional specifications.

Engineering Selection Recommendations

V30D45CHM3_A/I (Primary Part)

The V30D45CHM3_A/I is the primary specification for applications requiring automotive-grade Schottky diode arrays with explicit AEC-Q101 qualification. This part is actively produced and maintains full compliance with ROHS3 and REACH requirements. Current inventory of 853 pieces supports immediate procurement for production applications.

V30D45C-M3/I (Substitute Part)

The V30D45C-M3/I provides electrical and mechanical equivalence to the V30D45CHM3_A/I across all critical parameters. Both parts share identical electrical specifications, package configuration, and base product number (V30D45). The substitute part maintains ROHS3 compliance and unlimited moisture sensitivity rating. Higher inventory availability (2336 pieces) of the V30D45C-M3/I supports extended production runs and supply chain flexibility.

Both parts are manufactured by Vishay General Semiconductor - Diodes Division and are in active production status. Selection between these parts is determined by inventory availability and supply chain requirements rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Can V30D45C-M3/I be used as a direct replacement for V30D45CHM3_A/I?

A: Yes. Both parts share identical electrical specifications (45 V reverse voltage, 15 A rectified current, 570 mV forward voltage at 15 A), identical diode configuration (1 Pair Common Cathode), identical Schottky technology, and identical TO-263-3 D2PAK package. The parts are mechanically and electrically interchangeable without circuit modification or board layout changes.

Q: Are there differences in the package designation between these parts?

A: The supplier device package designation differs: V30D45CHM3_A/I uses TO-263AC (SMPD), while V30D45C-M3/I uses SMPD. Both designations refer to the same physical TO-263-3 D2PAK package with 2 leads plus tab. The package footprint and pin configuration are identical.

Q: What is the significance of the base product number V30D45?

A: The base product number V30D45 identifies the core diode array specification. Both the main part and substitute part share this base number, confirming they are variants of the same fundamental product with identical electrical performance and configuration.

Q: Are both parts suitable for automotive applications?

A: The V30D45CHM3_A/I carries explicit automotive grade designation and AEC-Q101 qualification. The V30D45C-M3/I data provided does not specify automotive grade or AEC-Q101 qualification status. For applications requiring documented automotive qualification, the V30D45CHM3_A/I is the specified part.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life and no special moisture control requirements during storage or handling.

Q: Are these parts RoHS compliant?

A: Yes. Both V30D45CHM3_A/I and V30D45C-M3/I are ROHS3 compliant and REACH unaffected.

Q: What is the operating temperature range for these diodes?

A: The junction operating temperature range for both parts is -40°C to 150°C, supporting applications across industrial, automotive, and high-temperature environments within this specification.

Q: What is the reverse leakage current specification?

A: Both parts specify 1.5 mA maximum reverse leakage current at the rated 45 V reverse voltage, ensuring consistent leakage characteristics across substitution.
