ESH2C-E3/5BT Equivalent & Substitute Parts

Part Overview

The ESH2C-E3/5BT is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates at 150 V DC reverse voltage with a 2 A average rectified current rating in a DO-214AA (SMB) package.

Substitute Part Grouping Explanation

Substitute parts for the ESH2C-E3/5BT are classified into two functional categories based on electrical parameter compatibility:

Category 1: Direct Parametric Equivalents

Parts that maintain identical or equivalent electrical specifications across all critical parameters:

Voltage - DC Reverse (Vr) (Max): 150 V
Current - Average Rectified (Io): 2 A
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
Package / Case: DO-214AA, SMB
Technology: Standard

Category 2: Functional Alternatives

Parts that operate within the same voltage and package class but with different current ratings or recovery characteristics. These parts are electrically compatible in applications where the higher current rating or alternative recovery time does not create design conflicts.

The following parameters determine substitution validity:

Voltage - DC Reverse (Vr) (Max) must equal or exceed 150 V
Current - Average Rectified (Io) must equal or exceed 2 A
Package / Case must be DO-214AA or SMB
Mounting Type must be Surface Mount
Speed Classification must support fast recovery operation

Engineering Selection Recommendations

Primary Equivalent (Recommended for Direct Replacement)

ESH2C-E3/52T (Vishay General Semiconductor) is the primary parametric equivalent. This part maintains identical electrical specifications and operating temperature range as the ESH2C-E3/5BT. Both parts are manufactured by the same supplier, classified as Active product status, and carry RoHS3 compliance. The difference between these parts is packaging configuration (Tape & Reel variant designation). This substitution requires no design modification.

Secondary Equivalents (Compatible with Minor Parameter Variations)

ES2C-13-F (Diodes Incorporated) and ES2C (Diotec Semiconductor) are functionally equivalent general-purpose rectifier diodes with 150 V / 2 A ratings in DO-214AA packages. Both maintain fast recovery speed classification and RoHS3 compliance. These parts exhibit lower reverse recovery time (20-25 ns versus 35 ns) and slightly higher reverse leakage current (5 µA versus 2 µA). Operating temperature ranges are reduced to -55°C ~ 150°C or -50°C ~ 150°C respectively. These substitutions are valid for applications where the reduced maximum junction temperature does not conflict with thermal design requirements.

MURS115T3G (onsemi) provides equivalent 150 V / 2 A performance with identical reverse recovery time and leakage current specifications. This part is classified as Last Time Buy product status, indicating discontinued production with limited availability. Extended operating temperature range (-65°C ~ 175°C) provides thermal margin beyond the primary part. This substitution is suitable only when supply continuity is not a concern.

Functional Alternative (Higher Current Rating)

STPS3150U (STMicroelectronics) is a Schottky diode with 150 V / 3 A rating. This part operates at higher current capacity and exhibits lower forward voltage drop (820 mV @ 3 A versus 930 mV @ 2 A). Schottky technology differs from standard rectifier technology. This substitution is valid only in applications where the higher current rating and lower forward voltage drop provide design benefit and where Schottky diode characteristics are acceptable.

Not Recommended for Direct Substitution

S3KB-13-F (Diodes Incorporated) operates at 800 V reverse voltage with 3 A current rating. This part is not electrically equivalent due to significantly higher voltage rating and different speed classification (Standard Recovery >500ns versus Fast Recovery ≤500ns). This part is listed in the substitute database but does not meet the electrical parameter requirements for direct substitution with the ESH2C-E3/5BT.

Frequently Asked Questions (FAQ)

Q: Can ESH2C-E3/52T be used as a direct replacement for ESH2C-E3/5BT?

A: Yes. ESH2C-E3/52T is a parametric equivalent manufactured by Vishay General Semiconductor with identical electrical specifications, operating temperature range, and package configuration. The part number suffix difference indicates packaging reel variant only. No design modification is required.

Q: What is the difference between the ESH2C-E3/5BT and ES2C-13-F?

A: Both parts are 150 V / 2 A general-purpose rectifier diodes in DO-214AA packages with fast recovery speed classification. ES2C-13-F exhibits faster reverse recovery time (25 ns versus 35 ns) and higher reverse leakage current (5 µA versus 2 µA). The maximum operating junction temperature is reduced from 175°C to 150°C. These differences are acceptable in most applications but must be verified against specific thermal and leakage requirements.

Q: Why is STPS3150U listed as a substitute if it has different specifications?

A: STPS3150U is a functional alternative with higher current capacity (3 A versus 2 A) and lower forward voltage drop due to Schottky technology. It maintains the same 150 V reverse voltage rating and DO-214AA package. This part is suitable for applications where increased current handling or reduced forward voltage drop provides design benefit. Schottky diode characteristics must be compatible with the application circuit.

Q: Can S3KB-13-F replace the ESH2C-E3/5BT?

A: No. S3KB-13-F operates at 800 V reverse voltage, which is significantly higher than the 150 V rating of the ESH2C-E3/5BT. Additionally, S3KB-13-F uses standard recovery speed classification (>500ns) rather than fast recovery (≤500ns). This part is not electrically equivalent and is not suitable for direct substitution.

Q: What does "Last Time Buy" product status mean for MURS115T3G?

A: Last Time Buy status indicates that the manufacturer has discontinued production of this part. Existing inventory may be available from distributors, but future supply cannot be guaranteed. While MURS115T3G is electrically equivalent to the ESH2C-E3/5BT, this status makes it unsuitable for new designs requiring long-term component availability.

Q: Are all substitute parts RoHS3 compliant?

A: All substitute parts listed in this reference are RoHS3 compliant. Compliance certification is maintained across all equivalent and alternative options.

Q: What is the significance of the DO-214AA package designation?

A: DO-214AA is the industry standard package designation for surface mount rectifier diodes in SMB (Small Molded Body) form factor. All parts in this reference use DO-214AA packaging, ensuring mechanical and thermal compatibility in PCB assembly and thermal management design.

Q: Can forward voltage drop differences affect circuit performance?

A: Yes. Forward voltage drop variations (875 mV to 930 mV across the substitute options) may affect circuit performance in precision rectification applications, voltage regulation circuits, or power supply designs where voltage drop directly impacts output voltage or efficiency. Verify forward voltage specifications against application requirements before substitution.
