Product details
Overview
ES2AAHM2G 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/25°C, and 50A peak surge current. It serves as a freewheeling or snubber diode in high-frequency DC-DC converters.
For engineers reviewing the ES2AAHM2G datasheet, ES2AAHM2G pinout, ES2AAHM2G application, or ES2AAHM2G 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, unidirectional 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 meeting J-STD-020 moisture sensitivity level 1 and JESD 201 class 2 whisker resistance.
The device delivers 35ns reverse recovery time under IF = 0.5A / IR = 1.0A / Irr = 0.25A test conditions, enabling high-efficiency operation in switching-mode power supplies up to several hundred kHz. Junction capacitance is 25pF at 1MHz and 4.0V reverse bias, supporting predictable high-frequency behavior.
Key Specifications

Applications
| DC-DC Converter Output Rectification | Snubber Network Diode |
|---|---|
Use Scenario: High-frequency isolated flyback or forward converter output stage delivering 5–24V at up to 2A. IC Role / Device Role / Timing Role: Unidirectional freewheeling rectifier conducting during transformer reset phase. Use Value: 35ns trr minimizes reverse recovery charge loss, improving efficiency over standard FR107-class diodes. | Use Scenario: RCD clamp circuit across MOSFET drain-source in offline SMPS to suppress voltage spikes. IC Role / Device Role / Timing Role: Fast turn-off diode that conducts only during transient voltage overshoot events. Use Value: Low VF (0.95V max) and fast trr reduce clamp energy dissipation and improve spike suppression fidelity. |
| Lighting Driver Freewheeling | Switching Inverter Auxiliary Rectification |
Use Scenario: Constant-current LED driver using buck topology with 100–300kHz switching frequency. IC Role / Device Role / Timing Role: Freewheeling path for inductor current when main switch is off. Use Value: DO-214AC footprint and 2A rating support compact, thermally efficient layout without derating. | Use Scenario: Auxiliary DC bus rectification in three-phase motor inverter gate drive or auxiliary supply. IC Role / Device Role / Timing Role: Input rectifier converting AC auxiliary winding output to stable DC. Use Value: 50V VRRM and 50A IFSM provide margin against line transients and startup surges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06 | VRRM = 600V, trr = 35ns, VF = 1.7V @ 2A - higher voltage rating but higher forward drop | Suitable for 400V+ input systems; less optimal for 50V-output circuits due to excess voltage margin and higher conduction loss | Select when system requires >100V reverse blocking; not drop-in for 50V designs due to different marking and thermal profile |
| MBR250 | VRRM = 50V, trr = 35ns, VF = 0.92V @ 2A - Schottky construction, zero Qrr, but limited to ≤125°C junction | Better efficiency below 125°C; unsuitable for high-temperature environments where ES2AAHM2G's 150°C rating is required | Prefer for low-temp, high-efficiency apps; avoid where TJ may exceed 125°C or where reverse leakage must be <10µA at 125°C |
Compared with STTH2R06 and MBR250, ES2AAHM2G offers optimal balance of 50V rating, 150°C operation, and 35ns recovery for cost-sensitive, thermally demanding 2A DC-DC outputs-neither alternative matches its exact voltage/temperature/reliability envelope.

FAQ
What is the maximum junction temperature rating for ES2AAHM2G?
The ES2AAHM2G has a maximum junction temperature (TJ) of +150°C and a minimum of –55°C. This wide operating range allows deployment in industrial and automotive under-hood environments where ambient temperatures exceed 85°C. The device's RθJA of 75°C/W enables thermal design predictability on standard FR-4 PCBs with adequate copper area.
Does ES2AAHM2G have a RoHS-compliant and halogen-free construction?
Yes, ES2AAHM2G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and the matte tin-plated leads are solderable per J-STD-002. These attributes make ES2AAHM2G suitable for consumer, industrial, and medical-grade end equipment with strict environmental compliance requirements.
What is the reverse recovery time specification for ES2AAHM2G and how is it tested?
The reverse recovery time (trr) for ES2AAHM2G is 35 ns maximum, measured under IF = 0.5A, IR = 1.0A, and Irr = 0.25A per JEDEC test conditions. This value is confirmed in the official Taiwan Semiconductor datasheet Version M2102 and reflects the device's suitability for high-frequency switching applications such as 200–500 kHz DC-DC converters.
Is ES2AAHM2G compatible with automated SMT assembly processes?
Yes, ES2AAHM2G uses the DO-214AC (SMA) package optimized for automated placement. It meets J-STD-020 moisture sensitivity level 1, requires no pre-baking, and supports standard reflow profiles. The low-profile design and matte tin leads ensure reliable solder joint formation and process yield in high-volume manufacturing.
What marking code identifies ES2AAHM2G on the device body?
ES2AAHM2G is marked with "ES2AA" on the device body, followed by date code and factory identifier per Taiwan Semiconductor's marking diagram. The "H" in the full part number denotes the M2G tape-and-reel packaging variant (7,500 pcs/reel), while "M2G" itself is not physically marked-only "ES2AA" appears on the SMA package.
