DGD2104AS8-13 Equivalent & Substitute Parts

Part Overview

The DGD2104AS8-13 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 part operates with a supply voltage range of 10V to 20V and features non-inverting input logic with a maximum bootstrap voltage of 600V. The DGD2104AS8-13 is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility across driven configuration, channel type, gate type, and electrical performance parameters.

Substitute Part Grouping Explanation

Substitute parts for the DGD2104AS8-13 are qualified based on strict electrical and mechanical compatibility. The following parameters define acceptable substitution:

• Driven configuration must be half-bridge
• Channel type must be synchronous
• Number of drivers must be 2
• Gate type must support IGBT and N-Channel MOSFET
• Supply voltage range must encompass 10V ~ 20V
• Input type must be non-inverting
• High side bootstrap voltage must be rated at 600V minimum
• Operating temperature range must cover -40°C ~ 150°C
• Package must be 8-SOIC form factor with 0.154" (3.90mm) width
• RoHS3 compliance is required

Two substitute parts meet these criteria: DGD2104MS8-13 (Diodes Incorporated) and IR2104STRPBF (Infineon Technologies). Both maintain identical driven configuration, channel type, driver count, gate type support, supply voltage range, input type, bootstrap voltage rating, operating temperature range, and package specifications.

Parameter Comparison

Engineering Selection Recommendations

Both DGD2104MS8-13 and IR2104STRPBF are active production parts suitable for replacing the obsolete DGD2104AS8-13. Selection between these substitutes depends on specific application requirements:

DGD2104MS8-13 offers enhanced peak output current specifications (290mA source, 600mA sink) and faster rise/fall times (70ns, 35ns) compared to the original part. This substitute is supplied in Tape & Reel packaging and maintains identical logic voltage thresholds and moisture sensitivity classification as the original.

IR2104STRPBF maintains electrical performance identical to the original DGD2104AS8-13 for peak output current and rise/fall time specifications. The logic voltage high threshold (VIH) is specified at 3V rather than 2.5V. This substitute features improved moisture sensitivity (MSL 2, 1 Year) and is supplied in Cut Tape and Digi-Reel packaging.

Both parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for new designs.

Frequently Asked Questions (FAQ)

Q: Can DGD2104MS8-13 be used as a direct replacement for DGD2104AS8-13?

A: Yes. DGD2104MS8-13 maintains all critical electrical and mechanical parameters required for half-bridge gate driver applications. The enhanced peak output current and faster switching times represent performance improvements over the original specification.

Q: What is the primary difference between DGD2104MS8-13 and IR2104STRPBF?

A: Both parts are functionally equivalent for the DGD2104AS8-13 application. DGD2104MS8-13 is manufactured by Diodes Incorporated with enhanced output current capability. IR2104STRPBF is manufactured by Infineon Technologies with identical performance to the original part and improved moisture sensitivity rating.

Q: Are there package compatibility concerns when substituting these parts?

A: No. All three parts use the 8-SOIC package with 0.154" (3.90mm) width, ensuring identical PCB footprint and mounting compatibility.

Q: Does the logic voltage difference between IR2104STRPBF (VIH 3V) and the original (VIH 2.5V) affect circuit operation?

A: The higher VIH threshold on IR2104STRPBF requires input signals to reach 3V for high-level recognition. This must be evaluated against the specific signal source characteristics in the application circuit.

Q: What is the significance of the MSL rating difference?

A: DGD2104AS8-13 and DGD2104MS8-13 are rated MSL 3 (168 hours), while IR2104STRPBF is rated MSL 2 (1 year). MSL 2 provides extended shelf life and reduced moisture absorption risk during storage and handling.

Q: Are both substitute parts available in production quantities?

A: Yes. DGD2104MS8-13 has 39,809 pieces in stock, and IR2104STRPBF has 63,945 pieces in stock as new original inventory.
