EPC2045 GaNFET N-Channel 100V 16A Die - Equivalent & Substitute Parts

Part Overview

The EPC2045 is an N-Channel GaNFET (Gallium Nitride Field Effect Transistor) rated for 100V drain-to-source voltage with 16A continuous drain current at 25°C. This component is supplied as a surface mount die in tape and reel packaging. The EPC2045 carries a product status of "Not For New Designs," indicating that EPC has transitioned this part to end-of-life status. For new circuit designs and ongoing production requirements, identification of functionally equivalent substitute components is necessary to ensure design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EPC2045 is determined by strict equivalence across the following critical electrical and mechanical parameters:

Voltage Rating: The substitute must maintain the same 100V Vdss rating to ensure compatibility with circuit voltage specifications.

Package and Mounting: The substitute must be supplied as a surface mount die to maintain mechanical and thermal interface compatibility with existing PCB designs and assembly processes.

Technology Platform: The substitute must utilize GaNFET technology within the eGaN® series to preserve switching characteristics and thermal performance.

Gate Voltage Compatibility: The substitute must support the same gate voltage range (+6V, -4V) to ensure compatibility with existing gate drive circuits.

Operating Temperature Range: The substitute must support the full -40°C to +150°C operating range to maintain thermal design margins.

The EPC2204 meets all these criteria and is classified as the manufacturer-recommended substitute for the EPC2045.

Parameter Comparison

Engineering Selection Recommendations

The EPC2204 is the manufacturer-recommended substitute for the EPC2045. The EPC2204 carries an "Active" product status, ensuring ongoing availability and support from the manufacturer.

Both components maintain identical voltage ratings (100V Vdss), gate voltage ranges (+6V, -4V), and operating temperature specifications (-40°C to +150°C). Both are supplied as surface mount dies within the eGaN® GaNFET series and meet identical RoHS3, REACH, and moisture sensitivity classifications.

The EPC2204 provides enhanced electrical performance relative to the EPC2045: continuous drain current is increased from 16A to 29A, on-resistance is reduced from 7 mOhm to 6 mOhm at 16A/5V operation, and the part maintains full backward compatibility with existing gate drive and thermal management designs.

For applications currently using the EPC2045, direct substitution with the EPC2204 is supported without circuit modification. The improved current rating and reduced on-resistance of the EPC2204 provide additional design margin and reduced power dissipation in equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can the EPC2204 be used as a direct replacement for the EPC2045 in existing designs?

A: Yes. Both components share identical voltage ratings (100V), gate voltage ranges (+6V, -4V), operating temperature ranges (-40°C to +150°C), and package specifications (surface mount die). The EPC2204 provides improved electrical performance with higher current rating (29A vs. 16A) and lower on-resistance (6 mOhm vs. 7 mOhm), making it a direct substitute without circuit redesign.

Q: What are the key differences between the EPC2045 and EPC2204?

A: The primary differences are continuous drain current (16A vs. 29A), on-resistance (7 mOhm vs. 6 mOhm), gate charge (6.5 nC vs. 7.4 nC), and input capacitance (685 pF vs. 851 pF). The EPC2204 also carries "Active" product status compared to the EPC2045's "Not For New Designs" status. All other electrical and mechanical parameters remain equivalent.

Q: Why is the EPC2045 marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that EPC has transitioned this component to end-of-life. New circuit designs should utilize the EPC2204, which offers superior performance characteristics and active manufacturer support.

Q: Are there any thermal management differences between these components?

A: Both components operate across the identical temperature range (-40°C to +150°C). The EPC2204's lower on-resistance (6 mOhm vs. 7 mOhm) results in reduced power dissipation at equivalent current levels, providing improved thermal performance in applications operating at or near the 16A current level.

Q: Do these components require different gate drive circuits?

A: No. Both components support identical gate voltage ranges (+6V, -4V) and threshold voltage specifications (2.5V maximum). Existing gate drive designs for the EPC2045 are fully compatible with the EPC2204 without modification.

Q: What is the moisture sensitivity level for these components?

A: Both the EPC2045 and EPC2204 carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both components are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
