Equivalent & Substitute Parts for ES2CHE3/5BT

Part Overview

The ES2CHE3/5BT is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 150 V DC reverse voltage and 2 A average rectified current in a surface mount DO-214AA (SMB) package. This part is classified as discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components for ongoing design support and procurement.

The ES2CHE3/5BT serves as a fast recovery rectifier diode suitable for standard rectification applications requiring automotive-grade qualification (AEC-Q101). Equivalent alternatives are available from both Vishay and other manufacturers, with varying product statuses and packaging configurations.

Substitute Part Grouping Explanation

Substitution of the ES2CHE3/5BT is determined by equivalence in the following critical parameters:

Voltage Rating: 150 V DC reverse voltage (Vr)
Current Rating: 2 A average rectified current (Io)
Forward Voltage: 900 mV maximum at 2 A
Package: DO-214AA (SMB) surface mount
Speed Classification: Fast recovery rectifier
Operating Temperature Range: -55°C to 150°C junction temperature
Compliance: ROHS3 compliant, AEC-Q101 automotive qualification

Substitute parts are grouped into two categories:

Direct Manufacturer Equivalents (Vishay): Parts with identical electrical specifications and automotive qualification, differing primarily in packaging configuration (Tape & Reel vs. bulk) or minor variations in reverse recovery time (20 ns vs. 30 ns).

Parametric Equivalents (Vishay & Diotec): Parts meeting all critical electrical parameters with active product status and full inventory availability.

Cross-Manufacturer Equivalent (onsemi): The MURS115T3G from onsemi provides electrical equivalence with extended operating temperature range (-65°C to 175°C) but carries Last Time Buy status.

Engineering Selection Recommendations

Primary Recommendation: ES2C-E3/52T (Vishay) is the preferred substitute. This part maintains identical electrical specifications to the ES2CHE3/5BT, carries active product status, and offers the highest inventory availability (30,400 units). It is ROHS3 compliant and suitable for automotive applications requiring AEC-Q101 qualification.

Secondary Recommendations:

ES2C-M3/5BT (Vishay): Active status with 921 units in stock. Identical electrical performance to the main part with full automotive qualification.
U2C-E3/52T (Vishay): Active status with 12,200 units available. Reverse recovery time of 27 ns provides improved switching performance compared to the 30 ns specification of the main part.
ES2C (Diotec): Highest inventory availability (43,700 units) with active product status. Reverse recovery time of 20 ns and lower reverse leakage current (5 µA) provide enhanced performance characteristics. Operating temperature range limited to -50°C to 150°C.

Alternative for Extended Temperature Range: MURS115T3G (onsemi) extends the operating temperature range to -65°C to 175°C but carries Last Time Buy status, limiting long-term procurement viability.

Not Recommended: ES2CHE3_A/I and ES2CHE3_A/H exhibit reduced reverse leakage current specification (10 µA @ 50 V vs. 10 µA @ 150 V) and shorter reverse recovery time (20 ns), which may not be suitable for all circuit topologies designed for the original 30 ns specification.

Frequently Asked Questions (FAQ)

Q: Can ES2C-E3/52T be used as a direct replacement for ES2CHE3/5BT?

A: Yes. Both parts share identical voltage ratings (150 V), current ratings (2 A), forward voltage specifications (900 mV @ 2 A), and package configuration (DO-214AA). Both are ROHS3 compliant and AEC-Q101 qualified. The primary difference is product status: ES2CHE3/5BT is discontinued while ES2C-E3/52T is active.

Q: What is the difference between the Tape & Reel (TR) packaging and bulk packaging?

A: Tape & Reel packaging is supplied on continuous carrier tape suitable for automated assembly equipment. Bulk packaging (indicated by "-" in the packaging field) typically refers to standard tube or tray configurations. Both packaging types contain identical components; the difference is in delivery format and handling for production environments.

Q: Why do some substitute parts have different reverse recovery times (trr)?

A: Reverse recovery time is a manufacturing parameter that varies within the fast recovery classification (≤ 500 ns). Parts with shorter trr values (20 ns or 27 ns) exhibit faster switching characteristics than the original 30 ns specification. These parts remain functionally equivalent for standard rectification applications and provide improved performance in high-frequency switching circuits.

Q: Is the MURS115T3G from onsemi a suitable replacement?

A: MURS115T3G meets all critical electrical parameters and provides extended operating temperature range (-65°C to 175°C vs. -55°C to 150°C). However, this part carries Last Time Buy status, indicating discontinued production. It is suitable for immediate replacement but not recommended for new long-term designs due to limited future availability.

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

A: Reverse leakage current is the small current flowing through the diode in reverse bias condition. Lower values indicate better reverse blocking characteristics. The ES2C from Diotec specifies 5 µA @ 150 V compared to 10 µA @ 150 V for most Vishay variants. Both values are acceptable for standard rectification; the lower value provides marginal improvement in efficiency and heat dissipation.

Q: Can I mix different substitute parts in the same circuit board assembly?

A: All listed substitute parts are electrically equivalent within the specified parameters and share identical package geometry (DO-214AA). Mixing different part numbers on the same board is permissible from an electrical standpoint. However, manufacturing and quality control procedures typically specify single part numbers per design to maintain traceability and consistency.

Q: Which substitute offers the best long-term procurement availability?

A: ES2C from Diotec offers the highest current inventory (43,700 units) and active product status, providing the strongest long-term procurement viability. ES2C-E3/52T from Vishay (30,400 units) is the second choice, offering both high availability and automotive qualification matching the original part.
