DGD21904S14-13 Equivalent & Substitute Parts

Part Overview

The DGD21904S14-13 is a half-bridge gate driver IC manufactured by Diodes Incorporated, designed for driving IGBT and N-Channel MOSFET configurations in power management applications. This device operates with independent dual channels and features non-inverting input logic. The DGD21904S14-13 is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The substitute part maintains functional and electrical compatibility while offering active product status and improved availability.

Substitute Part Grouping Explanation

Substitution of the DGD21904S14-13 with the DGD21904MS14-13 is based on strict electrical and mechanical parameter equivalence. Both parts share identical specifications across all critical functional parameters: half-bridge driven configuration, independent dual channels, IGBT and N-Channel MOSFET gate drive capability, supply voltage range (10V ~ 20V), logic voltage thresholds (0.8V, 2.5V), peak output current (4.5A source and sink), non-inverting input logic, maximum bootstrap voltage (600V), and switching characteristics (25ns rise time, 20ns fall time). Both devices are packaged in 14-SOIC surface-mount form factor with matching mechanical dimensions. Compliance certifications including ROHS3 and MSL rating are identical. The primary distinction is product status: DGD21904S14-13 is obsolete while DGD21904MS14-13 is active, and packaging format differs (standard packaging versus Tape & Reel). Operating temperature specification for the substitute extends to 125°C (TA) compared to 150°C (TJ) for the main part, representing a minor operational boundary difference within typical application ranges.

Parameter Comparison

Engineering Selection Recommendations

The DGD21904MS14-13 is the direct functional equivalent for the obsolete DGD21904S14-13. Selection of the substitute part is supported by complete electrical parameter equivalence, identical mechanical packaging, and matching compliance certifications (ROHS3 Compliant, REACH Unaffected). The substitute maintains active product status with established supply chain availability. The operating temperature specification difference (-40°C ~ 125°C TA versus -40°C ~ 150°C TJ) reflects measurement methodology variation rather than functional limitation and does not restrict substitution in standard industrial and commercial applications. The Tape & Reel packaging format of the substitute accommodates high-volume production workflows. Both parts share the same base product number (DGD21904) and are manufactured by Diodes Incorporated, confirming design continuity and pin-level compatibility.

Frequently Asked Questions (FAQ)

Q: Are DGD21904S14-13 and DGD21904MS14-13 pin-compatible? A: Yes. Both devices use the 14-SOIC package with identical pin assignments and electrical characteristics. Direct PCB substitution is supported without circuit modification.

Q: What is the significance of the operating temperature difference? A: The DGD21904S14-13 specifies -40°C ~ 150°C (TJ, junction temperature), while DGD21904MS14-13 specifies -40°C ~ 125°C (TA, ambient temperature). This reflects different measurement standards. For applications within -40°C ~ 125°C ambient range, both parts are functionally equivalent.

Q: Can I use DGD21904MS14-13 in existing designs originally specified for DGD21904S14-13? A: Yes. Electrical specifications, gate drive characteristics, and package dimensions are identical. No design changes are required.

Q: What is the difference between standard packaging and Tape & Reel format? A: Tape & Reel (TR) packaging is optimized for automated assembly and high-volume production. Standard packaging is suitable for lower-volume or manual assembly. Both formats contain identical components.

Q: Are both parts ROHS3 compliant? A: Yes. Both DGD21904S14-13 and DGD21904MS14-13 are ROHS3 Compliant with identical Moisture Sensitivity Level (MSL 3, 168 Hours).

Q: Why is DGD21904S14-13 listed as obsolete? A: Obsolete status indicates the part is no longer in active production. DGD21904MS14-13 represents the active equivalent for new designs and ongoing production support.
