Product details
Overview
ESH2CH from Taiwan Semiconductor is a 2 A, 150 V ultra-fast recovery surface-mount rectifier diode in DO-214AA (SMB) package, featuring 20 ns reverse recovery time, 0.9 V max forward voltage at 2 A, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or snubber diode in high-frequency DC/DC converters and automotive lighting systems.
For engineers reviewing the ESH2CH datasheet, ESH2CH pinout, ESH2CH application, or ESH2CH equivalent, key selection criteria include its 150 V repetitive peak reverse voltage, ultra-fast 20 ns trr, AEC-Q101 qualification, DO-214AA thermal performance (RθJA = 75 °C/W), and compatibility with automated SMT placement.
Technical Context
The ESH2CH uses a single-die, glass-passivated PN junction optimized for ultra-fast switching in high-efficiency power conversion. Its 20 ns reverse recovery time and low 0.9 V forward voltage drop minimize conduction and switching losses under 2 A DC forward current and 60 A surge conditions.
Designed for automotive environments, the ESH2CH meets AEC-Q101 stress test requirements and operates across –55 °C to +175 °C junction temperature range. Its DO-214AA (SMB) package supports moisture sensitivity level 1 per J-STD-020 and matte tin-plated leads compliant with J-STD-002 solderability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-2EY150-M3/57T | Same DO-214AA package, 2 A / 150 V, trr = 25 ns (max), VF = 0.95 V (max) - slightly slower and higher VF | Qualified to AEC-Q101 but not explicitly automotive-optimized in datasheet; less emphasis on moisture sensitivity level | Acceptable where 5 ns trr margin is available and lead-free solder profile compatibility is verified |
| ON Semiconductor MUR2150CT | TO-220AC package (not SMB), dual common-cathode configuration, 2 A / 150 V, trr = 35 ns - larger footprint, higher trr, different pinout | Designed for higher-power industrial supplies; lacks AEC-Q101 and J-STD-020 Level 1 compliance | Only suitable if board redesign accommodates through-hole mounting and thermal management for TO-220 |
Compared with VS-2EY150-M3/57T and MUR2150CT, the ESH2CH delivers tighter trr (20 ns vs. 25/35 ns), lower VF (0.9 V), and full automotive process validation - making it optimal for space-constrained, high-reliability automotive DC/DC stages where fast recovery and SMT compatibility are mandatory.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the ESH2CH?
The ESH2CH has a VRRM of 150 V, as specified in the Absolute Maximum Ratings table for the ESH2BH–ESH2DH series. This value is confirmed across all official documentation versions (A2102) and defines the highest reverse voltage the device can block repeatedly without breakdown under normal operating conditions. The ESH2CH must not be subjected to reverse voltages exceeding 150 V in circuit design.
Is the ESH2CH qualified for automotive applications?
Yes, the ESH2CH is explicitly AEC-Q101 qualified per the manufacturer's documentation. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD), confirming suitability for under-hood and cabin automotive electronics such as LED drivers and body control modules. The ESH2CH datasheet states this compliance unambiguously in the FEATURES section.
What is the reverse recovery time (trr) specification for the ESH2CH?
The ESH2CH has a maximum reverse recovery time (trr) of 20 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions. This value is published in the ELECTRICAL SPECIFICATIONS table and is consistent across all revision versions (A2102). The 20 ns trr enables efficient operation in high-frequency DC/DC converters up to 1 MHz.
Which package does the ESH2CH use, and what are its key mechanical attributes?
The ESH2CH uses the DO-214AA (SMB) surface-mount package. Key mechanical attributes include a UL 94V-0 flammability-rated molding compound, matte tin-plated leads compliant with J-STD-002, moisture sensitivity level 1 per J-STD-020, and a cathode band for polarity identification. Its weight is approximately 0.090 g.
Does the ESH2CH have a specified junction-to-ambient thermal resistance (RθJA)?
Yes, the ESH2CH has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W, as listed in the THERMAL PERFORMANCE section. This value assumes standard JEDEC test conditions (single device on 1-inch² copper pad) and is essential for calculating temperature rise under 2 A continuous forward current in PCB thermal design.
