ES3J R6G Equivalent & Substitute Parts

Part Overview

The ES3J R6G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 600 V DC reverse voltage and 3 A average rectified current in a surface mount DO-214AB (SMC) package. This component is classified as discontinued at DiGi Electronics, necessitating identification of equivalent substitute parts for ongoing design support and procurement continuity. Equivalent alternatives maintain identical electrical specifications and mechanical compatibility while offering active product status or improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ES3J R6G is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 600 V
• Current - Average Rectified (Io): 3 A
• Voltage - Forward (Vf) (Max) @ If: 1.7 V @ 3 A
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant

Acceptable Variation Parameters:

• Reverse Recovery Time (trr): Values ≤ 100 ns are acceptable within fast recovery classification
• Current - Reverse Leakage @ Vr: Values ≤ 10 µA @ 600 V are acceptable
• Capacitance @ Vr, F: Values between 30 pF and 63 pF @ 4V, 1MHz are acceptable
• Packaging format (Cut Tape, Tape & Reel): Interchangeable for component selection
• Product Status: Active status preferred over discontinued

All identified substitute parts meet these criteria and are classified as parametric equivalents.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Identical Electrical Characteristics):

ES3J V7G, ES3JH, ER3J_R1_00001, and UF3J_R1_00001 are all parametric equivalents to the ES3J R6G. Selection among these alternatives is based on product status and availability:

ES3JH is the preferred substitute, offering active product status with AEC-Q101 automotive qualification and Tape & Reel packaging. This part provides the highest assurance of long-term availability and supply chain continuity.

ER3J_R1_00001 (Panjit International Inc.) is an active alternative with superior reverse leakage characteristics (1 µA versus 10 µA) and higher inventory availability (42,000 pieces). This part is suitable for applications where lower leakage current provides performance benefits.

ES3J V7G maintains identical electrical specifications to the main part but remains discontinued at DiGi Electronics. This part is suitable only for existing inventory management or legacy system support.

UF3J_R1_00001 (Panjit International Inc.) is an active alternative with extended reverse recovery time (100 ns versus 35 ns) and higher capacitance (63 pF versus 30 pF). This part is suitable for applications where slower recovery characteristics are acceptable or beneficial.

All substitute parts maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and identical operating temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can ES3J V7G be used as a direct replacement for ES3J R6G?

A: Yes. ES3J V7G is a parametric equivalent with identical electrical specifications (600 V, 3 A, 1.7 V forward voltage, 35 ns recovery time). The primary difference is packaging format (Cut Tape versus unspecified). Both parts are discontinued at DiGi Electronics.

Q: What is the difference between ES3JH and ER3J_R1_00001?

A: Both are parametric equivalents with identical voltage, current, and forward voltage ratings. ER3J_R1_00001 has lower reverse leakage current (1 µA versus 10 µA) and higher capacitance (45 pF versus 30 pF). ES3JH includes AEC-Q101 automotive qualification. ER3J_R1_00001 has significantly higher inventory availability (42,000 pieces).

Q: Why does UF3J_R1_00001 have a longer reverse recovery time (100 ns)?

A: UF3J_R1_00001 is classified as a fast recovery diode with recovery time ≤ 500 ns, which exceeds the ES3J R6G specification of 35 ns. This part remains a parametric equivalent because both meet the fast recovery classification criteria. Applications sensitive to switching speed should prioritize parts with shorter recovery times (35 ns or 35 ns variants).

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

A: Yes. All substitute parts use the DO-214AB (SMC) surface mount package. Packaging formats differ (Cut Tape, Tape & Reel) but the physical component package is identical, ensuring mechanical compatibility in PCB assembly.

Q: Which substitute part has the best long-term availability?

A: ES3JH and ER3J_R1_00001 both have active product status. ER3J_R1_00001 has the highest inventory level (42,000 pieces) and active status, providing the strongest assurance of continued availability.

Q: Can these parts be used interchangeably in automotive applications?

A: ES3JH includes AEC-Q101 automotive qualification. Other substitutes (ER3J_R1_00001, UF3J_R1_00001) do not list automotive qualification. For automotive applications, ES3JH is the specified choice.

Q: What is the impact of different capacitance values (30 pF to 63 pF)?

A: Capacitance variation affects high-frequency circuit behavior and switching characteristics. Applications operating at frequencies where diode capacitance is a design parameter should select parts with matching capacitance values. For standard rectification applications, this variation is typically not critical.
