Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DGD1503S8-13 are identified based on the following critical parameters that determine functional compatibility:

• Half-bridge driven configuration with 2 independent drivers
• Supply voltage range of 10V to 20V
• Peak output current specifications: 290mA source, 600mA sink
• Logic voltage thresholds: VIL 0.8V, VIH 2.5V
• 8-SOIC surface mount package
• ROHS3 compliance and identical MSL rating (3, 168 Hours)

The substitute parts maintain these core electrical and mechanical specifications while offering active product status and enhanced availability.

Parameter Comparison

Engineering Selection Recommendations

Both DGD2003S8-13 and DGD2103MS8-13 are active products from Diodes Incorporated with ROHS3 compliance and identical MSL ratings, making them suitable for replacing the obsolete DGD1503S8-13.

DGD2003S8-13 is recommended for applications requiring non-inverting input configuration only, with a maximum bootstrap voltage of 200V. This part is suitable for standard half-bridge topologies operating within this voltage specification.

DGD2103MS8-13 is recommended for applications requiring both inverting and non-inverting input flexibility, with an extended maximum bootstrap voltage of 600V. This part supports both N-Channel MOSFET and IGBT gate driving, providing broader application coverage. The operating temperature range extends to 150°C (junction temperature), matching the original DGD1503S8-13 specification.

Frequently Asked Questions (FAQ)

Q: Can DGD2003S8-13 directly replace DGD1503S8-13 in all applications?

A: DGD2003S8-13 maintains identical supply voltage, output current, logic voltage, and package specifications. However, it features synchronous channel configuration and non-inverting input only, compared to the independent channels and dual input types of DGD1503S8-13. Additionally, its maximum bootstrap voltage is 200V versus 250V. Verify your circuit topology and input signal requirements before substitution.

Q: What are the key differences between DGD2003S8-13 and DGD2103MS8-13?

A: DGD2003S8-13 provides synchronous channel configuration with non-inverting inputs and 200V maximum bootstrap voltage. DGD2103MS8-13 provides independent channel configuration with inverting and non-inverting inputs and 600V maximum bootstrap voltage. Both maintain identical supply voltage, output current, and package specifications. Select based on your circuit's input signal type and maximum voltage requirements.

Q: Are all substitute parts in the same package?

A: Yes. DGD1503S8-13, DGD2003S8-13, and DGD2103MS8-13 are all housed in 8-SOIC (0.154", 3.90mm Width) surface mount packages, ensuring mechanical compatibility on existing PCB layouts.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant with identical MSL ratings of 3 (168 Hours), REACH unaffected status, and EAR99 ECCN classification.

Q: What is the temperature operating range difference?

A: DGD1503S8-13 and DGD2103MS8-13 both operate from -40°C to 150°C (junction temperature). DGD2003S8-13 operates from -40°C to 125°C (ambient temperature). For applications requiring the full -40°C to 150°C range, DGD2103MS8-13 is the appropriate substitute.
