DGD2101S8-13 Equivalent & Substitute Parts

Part Overview

The DGD2101S8-13 is a half-bridge gate driver IC manufactured by Diodes Incorporated, designed for driving IGBT and N-Channel MOSFET gates in power management applications. This part operates with a supply voltage range of 10V to 20V and features independent dual-channel configuration with non-inverting input logic. The DGD2101S8-13 is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain compatibility across electrical specifications, package form factor, and functional topology to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DGD2101S8-13 is determined by the following critical parameters:

Topology Compatibility: The substitute part must support half-bridge driven configuration with independent dual-channel architecture and non-inverting input logic.

Electrical Specifications: Supply voltage range must encompass or match 10V to 20V. Logic voltage thresholds (VIL, VIH) must be compatible with 0.8V and 2.5V levels. Peak output current specifications (source and sink) must meet or exceed 290mA and 600mA respectively. Bootstrap voltage rating must support minimum 600V operation.

Package Compatibility: All substitute parts must use 8-SOIC surface mount package with 0.154" (3.90mm) width to ensure PCB layout compatibility.

Compliance Requirements: Substitute parts must maintain ROHS3 compliance and EAR99 export classification.

The DGD2101MS8-13 qualifies as a direct substitute with identical electrical parameters and package form factor. The FAN7842MX and IR2101STRPBF are functionally equivalent alternatives with comparable specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

DGD2101MS8-13 is the primary substitute for the obsolete DGD2101S8-13. Both parts are manufactured by Diodes Incorporated with identical electrical specifications, matching supply voltage range, logic thresholds, output current ratings, and bootstrap voltage capability. The DGD2101MS8-13 maintains active product status and ROHS3 compliance. The primary difference is driven configuration topology: DGD2101MS8-13 supports high-side or low-side operation in addition to half-bridge configuration, providing greater application flexibility. Operating temperature specification differs slightly (TA vs TJ measurement basis), with DGD2101MS8-13 rated to 125°C ambient versus 150°C junction temperature for the original part.

FAN7842MX (onsemi) is a functionally equivalent half-bridge gate driver with active product status. This part meets all topology and package requirements with comparable electrical performance. Peak output current specifications exceed the original part (350mA source, 650mA sink). Rise and fall times are faster (60ns, 30ns). However, bootstrap voltage rating is limited to 200V, which is significantly lower than the 600V specification of the DGD2101S8-13. This limitation restricts FAN7842MX to applications with lower high-side voltage requirements. Moisture sensitivity is superior (MSL 1 vs MSL 3).

IR2101STRPBF (Infineon Technologies) is a half-bridge gate driver with active product status and ROHS3 compliance. This part maintains the 600V bootstrap voltage rating and supports the full operating temperature range (-40°C to 150°C). Peak output current specifications are lower than the original part (210mA source, 360mA sink), which may limit applicability in high-current gate drive scenarios. Rise and fall times are slower (100ns, 50ns). Logic voltage thresholds are higher (3.0V VIH). Moisture sensitivity is improved (MSL 2 vs MSL 3).

Frequently Asked Questions (FAQ)

Q: Can DGD2101MS8-13 directly replace DGD2101S8-13 in existing designs?

A: Yes. DGD2101MS8-13 is the direct substitute with identical electrical specifications, package form factor, and pin configuration. The expanded driven configuration capability (high-side or low-side in addition to half-bridge) does not affect half-bridge operation. No circuit modifications are required.

Q: What is the key limitation of FAN7842MX as a substitute?

A: FAN7842MX has a maximum bootstrap voltage rating of 200V, compared to 600V for the DGD2101S8-13. Applications requiring high-side voltage operation above 200V cannot use FAN7842MX. Verify your circuit's maximum high-side voltage requirement before selection.

Q: How do output current specifications affect part selection?

A: Peak output current (source and sink) determines the maximum gate charge delivery rate. DGD2101S8-13 specifies 290mA source and 600mA sink. FAN7842MX exceeds these ratings (350mA, 650mA), providing margin for high-current applications. IR2101STRPBF falls below specifications (210mA, 360mA), which may be insufficient for high-frequency switching or large gate capacitance loads.

Q: Are all substitute parts available in the same package?

A: Yes. All substitute parts use 8-SOIC surface mount package with 0.154" (3.90mm) width, ensuring PCB layout compatibility without redesign.

Q: What is the significance of operating temperature specification differences?

A: DGD2101S8-13 and FAN7842MX specify junction temperature (TJ) ratings of 150°C, while DGD2101MS8-13 specifies ambient temperature (TA) of 125°C. These represent different measurement methodologies. For applications operating near thermal limits, verify actual junction temperature in your thermal design to ensure compliance with the selected part's rating.

Q: Do logic voltage thresholds affect circuit compatibility?

A: Logic voltage thresholds (VIL, VIH) define the input signal levels required for proper gate driver operation. DGD2101S8-13 specifies 0.8V and 2.5V. FAN7842MX and IR2101STRPBF have slightly higher VIH thresholds (2.9V and 3.0V respectively). If your control circuit outputs 2.5V logic levels, verify compatibility with the substitute part's input threshold before selection.

Q: What does Moisture Sensitivity Level (MSL) indicate?

A: MSL defines the maximum time a component can be exposed to ambient moisture before soldering. DGD2101S8-13 has MSL 3 (168 hours maximum), while FAN7842MX has MSL 1 (unlimited storage). Lower MSL values provide greater handling flexibility and reduced risk of moisture-induced failures during manufacturing.
