AP2820EM-G1 Equivalent & Substitute Parts

Part Overview

The AP2820EM-G1 is a Power Switch/Driver IC manufactured by Diodes Incorporated, designed for USB switching applications with 1:1 N-Channel configuration and 2.5A output capability. This component operates as a high-side switch with on/off interface control and integrated fault protection including current limiting, over-temperature, reverse current, and UVLO (Under-Voltage Lock-Out) functions.

The AP2820EM-G1 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AP2820EM-G1 is determined by strict alignment of the following critical parameters:

• Switch Configuration: 1:1 ratio, N-Channel, high-side output topology
• Electrical Performance: 2.5A maximum output current capability
• Load Voltage Range: Minimum 2.7V operation (substitute must support ≥2.7V)
• Interface Type: On/Off control with non-inverting input
• Fault Protection: Current limiting, over-temperature, reverse current, and UVLO protection
• Operating Temperature: -40°C to 85°C range
• Compliance: ROHS3 compliance and surface mount packaging

The BD82024FVJ-E2 manufactured by Rohm Semiconductor meets these substitution criteria. While packaging differs (8-TSSOP-BJ vs. 8-SOIC), electrical specifications and functional characteristics align within acceptable tolerance for equivalent operation.

Parameter Comparison

Engineering Selection Recommendations

The BD82024FVJ-E2 is the qualified substitute for the obsolete AP2820EM-G1 based on functional equivalence and compliance alignment. Both components maintain ROHS3 compliance and MSL-1 moisture sensitivity ratings, ensuring regulatory and environmental compatibility.

Key considerations for selection:

• Product Status: BD82024FVJ-E2 is active and in production, providing long-term supply chain stability compared to the obsolete AP2820EM-G1.
• Electrical Equivalence: Both parts deliver 2.5A output current with identical fault protection architecture (current limiting, over-temperature, reverse current, UVLO).
• Load Voltage Compatibility: BD82024FVJ-E2 operates at 2.8V minimum versus 2.7V for the original part. Applications requiring operation below 2.8V require design review.
• On-Resistance Difference: BD82024FVJ-E2 exhibits 90mOhm typical Rds On versus 60mOhm for AP2820EM-G1. This 30mOhm increase results in proportionally higher power dissipation under maximum current conditions and requires thermal analysis for high-current applications.
• Package Transition: PCB layout modification is required due to package change from 8-SOIC to 8-TSSOP. Pin-to-pin compatibility must be verified against schematic documentation.

Frequently Asked Questions (FAQ)

Q: Can BD82024FVJ-E2 directly replace AP2820EM-G1 without PCB modification?

A: No. The packages differ (8-SOIC vs. 8-TSSOP), requiring PCB layout changes. Pin assignments must be verified against both datasheets before implementation.

Q: What is the impact of the 30mOhm increase in Rds On?

A: At maximum 2.5A output current, the BD82024FVJ-E2 dissipates approximately 0.5625W (I²R = 2.5² × 0.090) compared to 0.375W for the AP2820EM-G1. Thermal management and PCB copper area must be evaluated for applications operating at sustained maximum current.

Q: Is the 2.8V minimum load voltage of BD82024FVJ-E2 compatible with my design?

A: If your application requires operation below 2.8V, the BD82024FVJ-E2 is not suitable. The AP2820EM-G1 specification of 2.7V minimum must be maintained through alternative component selection or design modification.

Q: Are both parts ROHS3 compliant?

A: Yes. Both AP2820EM-G1 and BD82024FVJ-E2 are ROHS3 compliant with MSL-1 moisture sensitivity ratings, meeting environmental and regulatory requirements.

Q: What additional features does BD82024FVJ-E2 provide?

A: BD82024FVJ-E2 includes load discharge functionality in addition to the status flag present in both parts. This feature may provide operational benefits in specific USB switching applications.

Q: Is inventory availability a factor in selecting BD82024FVJ-E2?

A: Yes. BD82024FVJ-E2 is in active production with 8137 pcs in stock, whereas AP2820EM-G1 is obsolete with limited remaining inventory (1032 pcs). For new designs or long-term production, BD82024FVJ-E2 ensures supply chain continuity.
