ES3D Equivalent & Substitute Parts Reference

Part Overview

The ES3D is a general-purpose rectifier diode rated for 200 V DC reverse voltage and 3 A average rectified current, packaged in the DO-214AB (SMC) surface mount configuration. Manufactured by SMC Diode Solutions, this component is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and production continuity. The ES3D features fast recovery characteristics with a reverse recovery time of 35 nanoseconds, making it suitable for applications requiring efficient switching performance in rectification circuits.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ES3D is determined by strict equivalence across the following critical electrical and mechanical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) Maximum: 200 V
• Current - Average Rectified (Io): 3 A
• Reverse Recovery Time (trr): 35 ns
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount

Acceptable Variation Parameters:

• Voltage - Forward (Vf) Maximum @ If: 950 mV @ 3 A (identical across all substitutes)
• Current - Reverse Leakage @ Vr: 5 µA to 10 µA @ 200 V (within acceptable leakage tolerance)
• Operating Temperature - Junction: -55°C to -65°C minimum; 150°C maximum (all meet or exceed ES3D range)
• Capacitance @ Vr, F: 45 pF @ 4V, 1MHz (identical across all substitutes)

All identified substitute parts maintain electrical performance equivalence within these parameters while offering active product status and improved compliance certifications.

Engineering Selection Recommendations

ER3D (SMC Diode Solutions)

The ER3D is a direct manufacturer equivalent from SMC Diode Solutions with active product status. It maintains identical electrical specifications to the ES3D across all critical parameters including voltage rating, current capacity, forward voltage, and reverse recovery time. The ER3D offers an extended operating temperature range (-65°C to 150°C) compared to the ES3D (-55°C to 150°C), providing enhanced thermal margin. This part carries ROHS3 compliance and is available in Tape & Reel packaging. Selection of the ER3D is appropriate for applications requiring continuity with the original SMC Diode Solutions product line.

ER3D_R1_00001 (Panjit International Inc.)

The ER3D_R1_00001 is a parametric equivalent manufactured by Panjit International Inc. with active product status. This part maintains all critical electrical specifications identical to the ES3D. The ER3D_R1_00001 features superior reverse leakage characteristics (1 µA @ 200 V versus 5 µA @ 200 V), resulting in lower standby current consumption. This part carries ROHS3 compliance and REACH Unaffected status. Selection of the ER3D_R1_00001 is appropriate for applications where reduced leakage current provides performance benefits and where multi-source qualification is acceptable.

ES3DH (Taiwan Semiconductor Corporation)

The ES3DH is a parametric equivalent manufactured by Taiwan Semiconductor Corporation with active product status. This part maintains all critical electrical specifications identical to the ES3D. The ES3DH carries automotive-grade qualification (AEC-Q101) and ROHS3 compliance, making it suitable for automotive and high-reliability applications. The reverse leakage specification (10 µA @ 200 V) is within acceptable tolerance. Selection of the ES3DH is appropriate for automotive applications or where AEC-Q101 qualification is a design requirement.

Frequently Asked Questions (FAQ)

Q: Can the ES3D be directly replaced with any of the listed substitute parts?

A: Yes. All listed substitute parts (ER3D, ER3D_R1_00001, and ES3DH) maintain electrical equivalence across the critical parameters that determine diode functionality: 200 V reverse voltage rating, 3 A average rectified current, 35 ns reverse recovery time, and DO-214AB SMC package. Direct substitution is supported from an electrical and mechanical standpoint.

Q: What is the difference between the three substitute options?

A: The three substitutes differ in manufacturer, product compliance certifications, and reverse leakage characteristics. The ER3D is from SMC Diode Solutions (original manufacturer) with extended temperature range. The ER3D_R1_00001 from Panjit International Inc. features lower reverse leakage (1 µA). The ES3DH from Taiwan Semiconductor Corporation includes automotive-grade AEC-Q101 qualification. All three maintain identical voltage, current, and switching speed specifications.

Q: Does the packaging format affect substitution compatibility?

A: The packaging format (Tape & Reel versus bulk) does not affect electrical or mechanical compatibility. All substitute parts are supplied in Tape & Reel (TR) format, which is standard for surface mount production. The DO-214AB SMC package footprint and mounting requirements remain identical across all parts.

Q: Are there any compliance or regulatory differences between the substitutes?

A: Yes. The ER3D carries REACH Affected status, while ER3D_R1_00001 and ES3DH carry REACH Unaffected status. All three substitutes are ROHS3 compliant. The ES3DH includes AEC-Q101 automotive qualification. Applications subject to REACH restrictions should select ER3D_R1_00001 or ES3DH. Automotive applications should prioritize ES3DH.

Q: What is the significance of the reverse leakage current differences?

A: Reverse leakage current (5 µA for ES3D and ER3D, 1 µA for ER3D_R1_00001, and 10 µA for ES3DH) represents standby current consumption when the diode is reverse-biased. Lower leakage reduces power dissipation in standby conditions. The ER3D_R1_00001 offers the lowest leakage, beneficial for battery-powered or low-power applications. All values remain within acceptable operating parameters for general-purpose rectification.

Q: Is the extended temperature range of the ER3D (-65°C minimum) significant?

A: The ER3D's extended minimum operating temperature (-65°C versus -55°C) provides additional thermal margin for applications exposed to extreme cold environments. For applications operating within the -55°C to 150°C range, this difference is not functionally significant. Selection should be based on actual application temperature requirements.

Q: Can the ES3DH be used in non-automotive applications?

A: Yes. The ES3DH is a general-purpose rectifier diode that meets all electrical specifications for the ES3D. The AEC-Q101 automotive qualification is an additional certification that does not restrict use in non-automotive applications. The ES3DH is suitable for any application requiring a 200 V, 3 A, 35 ns recovery time diode in DO-214AB packaging.
