ESH3D R7 Equivalent & Substitute Parts

Part Overview

The ESH3D R7 is a general-purpose rectifier diode rated for 200 V DC reverse voltage and 3 A average rectified current in a surface mount DO-214AB (SMC) package. Manufactured by Taiwan Semiconductor Corporation, this component is classified as discontinued at DiGi Electronics. The part operates across a junction temperature range of -55°C to 175°C and meets ROHS3 compliance requirements.

Due to the discontinued status of the ESH3D R7, equivalent and substitute parts from active manufacturers are necessary for ongoing production, design revisions, and procurement continuity. The substitute parts listed maintain the core electrical specifications while offering availability through active product lines.

Current - Average Rectified (Io): 3 A minimum
Voltage - Forward (Vf) (Max) @ If: 900 mV or lower @ 3 A
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Physical and Environmental Requirements:

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

The ESH3D-E3/57T, ESH3D-E3/9AT, ESH3D-M3/57T, and ESH3D-M3/9AT from Vishay General Semiconductor - Diodes Division are direct parametric equivalents. These parts maintain identical voltage and current ratings, forward voltage characteristics, and operating temperature range (-55°C ~ 175°C). All are ROHS3 compliant with MSL 1 rating. These parts are currently in active production status with substantial inventory availability.

Secondary Substitute (Minor Parameter Variance):

The ES3D-E3/9AT from Vishay General Semiconductor - Diodes Division meets all core electrical requirements with identical voltage, current, and forward voltage specifications. The operating temperature range is -55°C ~ 150°C, which covers standard industrial applications but does not extend to the full 175°C upper limit of the original part. This part is active with high inventory availability (110,400 units).

Alternative Substitute (Extended Temperature Consideration):

The ER3D-TP from Micro Commercial Co maintains 200 V reverse voltage and 3 A current ratings. Forward voltage is specified at 950 mV @ 3 A, which is 50 mV higher than the original specification. The operating temperature range is -50°C ~ 175°C, which does not extend to the -55°C lower limit. This part is active with high inventory availability (16,840 units).

Automotive-Grade Options:

The ESH3DHE3_A/H and ESH3DHE3_A/I are automotive-qualified variants (AEC-Q101) with identical electrical specifications to the primary substitutes. These parts are suitable for applications requiring automotive-grade component certification and are currently in active production.

Frequently Asked Questions (FAQ)

Q: Can the ER3D-TP be used as a direct replacement for the ESH3D R7?

A: The ER3D-TP is electrically compatible for most applications. It meets the 200 V reverse voltage and 3 A current requirements. However, the forward voltage is specified at 950 mV @ 3 A compared to 900 mV for the original part, representing a 50 mV difference. Additionally, the operating temperature range is -50°C ~ 175°C, which does not extend to the -55°C lower limit of the ESH3D R7. Applications requiring operation below -50°C or with strict forward voltage specifications should use alternative substitutes.

Q: What is the difference between ESH3D-E3/57T and ESH3D-E3/9AT?

A: Both parts are parametric equivalents with identical electrical specifications: 200 V reverse voltage, 3 A current, 900 mV forward voltage, and -55°C ~ 175°C operating temperature range. The primary difference is packaging format: ESH3D-E3/57T is supplied in Tape & Reel (TR) format, while ESH3D-E3/9AT is supplied in Tape & Reel (TR) format as well. Both are ROHS3 compliant with MSL 1 rating.

Q: Are the automotive-grade variants (ESH3DHE3_A/H and ESH3DHE3_A/I) suitable for non-automotive applications?

A: Yes. The automotive-grade variants meet all electrical specifications of the standard industrial parts and are AEC-Q101 qualified. They can be used in non-automotive applications without functional limitation. The automotive qualification represents an additional quality assurance level and does not restrict use in other applications.

Q: What is the significance of the reverse recovery time (trr) variation among substitutes?

A: The ESH3D R7 specifies a reverse recovery time of 20 ns, while most substitute parts specify 40 ns. Both values fall within the fast recovery classification (≤ 500ns, > 200mA). The longer recovery time in substitutes does not affect functional compatibility in standard rectification applications. Applications with specific switching frequency or EMI requirements should evaluate the impact of the 20 ns difference.

Q: Can ES3D-E3/9AT be used in applications requiring the full -55°C ~ 175°C temperature range?

A: The ES3D-E3/9AT is specified for -55°C ~ 150°C operation, which does not extend to the 175°C upper limit of the ESH3D R7. Applications requiring sustained operation at temperatures between 150°C and 175°C should use ESH3D-E3/57T, ESH3D-E3/9AT (Vishay variant), ESH3D-M3/57T, ESH3D-M3/9AT, or the automotive-grade variants, all of which support -55°C ~ 175°C.

Q: What packaging options are available for substitutes?

A: Substitute parts are available in multiple packaging formats: Tape & Reel (TR) for high-volume automated assembly, Cut Tape (CT) for lower-volume or mixed-component orders, and Digi-Reel® format. All maintain the DO-214AB (SMC) surface mount package. Selection should be based on production volume and assembly process requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). All parts are REACH unaffected and classified under ECCN EAR99 with HTSUS code 8541.10.0080.
