Key Parameters

Substitute Part Grouping Explanation

Substitution for the DGD2104S8-13 is determined by strict equivalence across the following critical parameters:

• Driven configuration (half-bridge topology)
• Channel type (synchronous operation)
• Number of drivers (2 channels)
• Gate type compatibility (IGBT and N-Channel MOSFET)
• Supply voltage range (10V ~ 20V)
• Input type (non-inverting logic)
• Maximum bootstrap voltage (600V minimum)
• Package form factor (8-SOIC)
• Operating temperature range (-40°C ~ 150°C)

The identified substitutes maintain these core electrical and mechanical specifications, ensuring functional compatibility in half-bridge gate driver applications. Variations in peak output current and rise/fall time characteristics remain within acceptable operational margins for typical power management circuits.

Parameter Comparison

Engineering Selection Recommendations

DGD2104MS8-13 is the primary substitute for the obsolete DGD2104S8-13. Both parts are manufactured by Diodes Incorporated and share identical electrical specifications, including peak output currents (290mA source, 600mA sink) and timing characteristics (70ns rise, 35ns fall). The DGD2104MS8-13 is currently in active production status with higher inventory availability. The only difference is packaging format: DGD2104MS8-13 is supplied in Tape & Reel format versus the original tube packaging.

IR2104STRPBF, manufactured by Infineon Technologies, is a functional equivalent with the same half-bridge topology and operating parameters. This part exhibits lower peak output current specifications (210mA source, 360mA sink) and slower timing characteristics (100ns rise, 50ns fall). The IR2104STRPBF maintains ROHS3 compliance and operates within the same temperature and voltage ranges. Selection of the IR2104STRPBF requires verification that reduced output current and extended switching times are acceptable for the target application.

Both substitutes are ROHS3 compliant and REACH unaffected, meeting regulatory requirements equivalent to the original part.

Frequently Asked Questions (FAQ)

Q: Can DGD2104MS8-13 be used as a direct replacement for DGD2104S8-13?

A: Yes. The DGD2104MS8-13 is electrically and functionally identical to the DGD2104S8-13. The only difference is packaging format (Tape & Reel versus tube). Both parts share the same pin configuration, electrical specifications, and operating characteristics.

Q: What are the key differences between DGD2104MS8-13 and IR2104STRPBF?

A: Both parts function as half-bridge gate drivers with identical supply voltage ranges and bootstrap voltage ratings. The IR2104STRPBF has lower peak output current (210mA source, 360mA sink versus 290mA/600mA) and slower switching times (100ns/50ns versus 70ns/35ns). The logic voltage threshold for VIH differs slightly (3V versus 2.5V). These differences may impact performance in high-frequency or high-current applications.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 8-SOIC package with identical pinout and can be used interchangeably from a mechanical and electrical interface perspective, provided the electrical performance differences are acceptable for the application.

Q: What is the significance of the obsolete status for DGD2104S8-13?

A: Obsolete status indicates the part is no longer manufactured. Existing inventory may be limited and subject to availability constraints. DGD2104MS8-13 is the recommended replacement as it maintains full electrical equivalence and is in active production.

Q: Do all substitutes meet the same compliance standards?

A: Yes. DGD2104MS8-13 and IR2104STRPBF are both ROHS3 compliant and REACH unaffected, matching the compliance profile of the original DGD2104S8-13.
