Product details
Overview
ES2AA M2G from Taiwan Semiconductor is a 2A, 50V super fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 35ns reverse recovery time, 0.95V max forward voltage at 2A, and 50A peak surge current. It serves as a freewheeling or snubber diode in high-frequency DC/DC converters and switching inverters.
For engineers reviewing the ES2AA M2G datasheet, ES2AA M2G pinout, ES2AA M2G application, or ES2AA M2G equivalent, key selection criteria include VRRM = 50V, IF = 2A, trr = 35ns, thermal resistance RθJA = 75°C/W, and DO-214AC mechanical compatibility with automated SMT assembly.
Technical Context
This single-die silicon rectifier uses glass-passivated junction technology to achieve stable performance across -55°C to +150°C junction temperature range. Its low-profile DO-214AC package supports high-density PCB layouts while maintaining J-STD-020 Level 1 moisture sensitivity and JESD201 Class 2 whisker resistance.
The device delivers super-fast switching with 35ns reverse recovery time under IF = 0.5A / IR = 1.0A test conditions, enabling high-efficiency operation in 100kHz–500kHz switching topologies. Junction capacitance is 25pF at 1MHz and 4V reverse bias, supporting minimal capacitive loading in snubber networks.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06U (STMicroelectronics) | VRRM = 600V, trr = 30ns, VF = 1.15V @ 2A - higher voltage rating but higher forward drop | Suitable for universal-input PFC where 600V blocking is required; less optimal for 50V-specific rails due to over-spec | Select ES2AA M2G when VRRM = 50V suffices and lowest VF is prioritized for efficiency |
| MBR2505CT (ON Semiconductor) | 5A dual common-cathode Schottky, VF = 0.52V @ 2A, no reverse recovery - zero trr but VRRM = 50V only | Better for ultra-low-loss 50V outputs but requires dual-diode layout and lacks 50A surge capability | Choose ES2AA M2G for robustness in surge-prone snubber/freewheel roles where Schottky leakage or thermal runaway risk exists |
Compared with STTH2R06U and MBR2505CT, ES2AA M2G offers the optimal balance of low VF, verified 35ns trr, and 50V-specific optimization - delivering higher efficiency than 600V alternatives and greater surge resilience than Schottky counterparts in 50V DC/DC and inverter freewheeling.

FAQ
What is the maximum junction temperature rating for ES2AA M2G?
The ES2AA M2G has a maximum junction temperature (TJ) of +150°C, with operational capability from -55°C to +150°C. This rating allows reliable use in enclosed industrial environments and automotive under-hood applications when mounted on adequate PCB copper area. Thermal design must account for RθJA = 75°C/W to avoid exceeding this limit under full 2A load.
Does ES2AA M2G have a specified reverse recovery time, and how is it measured?
Yes, ES2AA M2G specifies a maximum reverse recovery time (trr) of 35ns. It is measured under standardized conditions: IF = 0.5A, IR = 1.0A, Irr = 0.25A, per JEDEC guidelines. This value is confirmed across production lots and is critical for minimizing switching loss in high-frequency DC/DC converters where ES2AA M2G is commonly deployed.
Is ES2AA M2G compatible with lead-free reflow soldering processes?
Yes, ES2AA M2G is fully compatible with lead-free reflow soldering. Its matte tin-plated leads meet J-STD-002 solderability requirements, and its DO-214AC package is rated for peak reflow temperatures up to 260°C. The device carries J-STD-020 Level 1 moisture sensitivity, eliminating pre-bake requirements and supporting direct placement into standard Pb-free SMT lines.
What does the "M2G" suffix indicate in ES2AA M2G?
The "M2G" suffix in ES2AA M2G denotes Taiwan Semiconductor's internal packaging and environmental compliance variant: "M2" refers to tape-and-reel packaging per ordering code ES2xA, and "G" indicates halogen-free construction per IEC 61249-2-21. This matches the DO-214AC (SMA) package and RoHS-compliant material set documented in the ES2AA M2G datasheet.
Can ES2AA M2G be used as a direct replacement for older ES2AA versions with different suffixes?
ES2AA M2G maintains identical electrical specifications, thermal performance, and mechanical dimensions as prior ES2AA variants (e.g., ES2AA M2102). The M2G revision incorporates updated halogen-free molding compound and refined process controls but preserves full functional and form-fit compatibility - making it a seamless drop-in replacement in existing designs using ES2AA M2G or ES2AA M2102.
