Product details
Overview
ES2BAHM2G from Taiwan Semiconductor is a 2 A, 100 V super fast recovery surface-mount rectifier diode in DO-214AC (SMA) package, featuring 35 ns reverse recovery time, 0.95 V forward voltage at 2 A, and 50 A peak surge current - used for snubber networks and freewheeling in DC-DC converters.
For engineers reviewing the ES2BAHM2G datasheet, ES2BAHM2G pinout, ES2BAHM2G application, or ES2BAHM2G equivalent, key selection criteria include repetitive peak reverse voltage (100 V), thermal resistance (RθJL = 20 °C/W), junction temperature range (–55 to +150 °C), and RoHS/halogen-free compliance for industrial power conversion designs.
Technical Context
This device is a single-die, unidirectional silicon rectifier optimized for high-frequency switching applications. Its super fast recovery (trr ≤ 35 ns) minimizes switching losses in SMPS and inverters, while glass passivation ensures stable junction performance under thermal cycling.
The DO-214AC (SMA) package supports automated placement and provides low-profile mounting with matte tin-plated leads compliant to J-STD-002. Polarity is marked by a cathode band; moisture sensitivity level is J-STD-020 Level 1.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R010DJF | 100 V VRRM, 2 A IF, trr = 30 ns, DO-214AC, but higher VF (1.05 V) | Slightly faster recovery but higher conduction loss; requires thermal reassessment | Prefer when ultra-low trr dominates over VF in high-frequency designs |
| ON Semi MUR210EG | 100 V VRRM, 2 A IF, trr = 35 ns, same DO-214AC, VF = 0.93 V, but not halogen-free | Identical electrical specs but lacks IEC 61249-2-21 halogen-free certification | Select when halogen-free compliance is not required and cost is prioritized |
Compared with STTH2R010DJF and MUR210EG, ES2BAHM2G offers balanced trade-offs: identical trr to MUR210EG with halogen-free assurance, and lower VF than STTH2R010DJF - making it optimal for thermally constrained, environmentally regulated industrial power supplies.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for ES2BAHM2G?
The ES2BAHM2G has a VRRM of 100 V, meaning it reliably blocks up to 100 V of reverse voltage in repetitive operation without breakdown. This rating is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor ES2AA–ES2JA datasheet (Version M2102). Exceeding this voltage risks irreversible junction failure. The ES2BAHM2G is part of a family spanning 50 V to 600 V, with 'BA' denoting the 100 V variant.
Does ES2BAHM2G have a halogen-free construction?
Yes, ES2BAHM2G is halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the Taiwan Semiconductor ES2AA–ES2JA datasheet. The molding compound and internal materials contain no bromine, chlorine, or other regulated halogens. This makes ES2BAHM2G suitable for environmentally sensitive applications including medical devices and green-certified industrial equipment where halogen content is restricted.
What is the forward voltage (VF) of ES2BAHM2G at rated current?
The forward voltage of ES2BAHM2G is 0.95 V at 2 A and 25 °C junction temperature, per the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents typical conduction loss. At elevated temperatures (e.g., 125 °C), VF decreases slightly due to semiconductor physics, but system design should use the 25 °C value for worst-case thermal margining in the ES2BAHM2G application.
Is ES2BAHM2G compatible with standard reflow soldering processes?
Yes, ES2BAHM2G is compatible with standard Pb-free reflow soldering per J-STD-020 Level 1 moisture sensitivity classification - meaning it can be mounted without pre-baking. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the DO-214AC (SMA) package withstands peak reflow temperatures up to 260 °C. No special handling is needed before assembly, simplifying ES2BAHM2G integration into high-volume SMT lines.
What does the 'M2G' suffix indicate in ES2BAHM2G?
The 'M2G' suffix in ES2BAHM2G denotes Taiwan Semiconductor's internal packaging and environmental coding: 'M2' specifies tape-and-reel packaging (7,500 units per reel), and 'G' indicates green (halogen-free) compound per IEC 61249-2-21. This matches the ordering information in the ES2AA–ES2JA datasheet and distinguishes ES2BAHM2G from non-halogen variants such as ES2BAHM2. The full marking on the device body is 'ES2BA'.
