Product details
Overview
ES1A M2G from Taiwan Semiconductor is a 1 A, 50 V super fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 35 ns reverse recovery time, 0.95 V forward voltage at 1 A, and 30 A peak surge current - deployed in DC/DC converter output stages and snubber networks.
For engineers reviewing the ES1A M2G datasheet, ES1A M2G pinout, ES1A M2G application, or ES1A M2G equivalent, key selection criteria include repetitive peak reverse voltage (50 V), thermal resistance (RθJL = 35 °C/W), junction temperature range (–55 to +150 °C), and RoHS/halogen-free compliance for industrial power conversion designs.
Technical Context
The ES1A M2G uses a glass-passivated single-die silicon junction optimized for high-frequency switching, with ultra-fast trr ≤ 35 ns enabling efficient operation in 100 kHz–1 MHz SMPS topologies. Its DO-214AC package supports automated placement and meets J-STD-020 moisture sensitivity level 1.
Electrical behavior is defined by low VF (max 0.95 V @ 1 A, 25 °C), low IR (≤ 5 µA @ 25 °C, rated VR), and stable CJ (16 pF @ 1 MHz, 4 V), making it suitable for freewheeling and clamp functions where minimal stored charge and rapid turn-off are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (Avg) | 1 A - continuous forward current rating defines maximum steady-state conduction capability in output rectification paths |
| VRRM | 50 V - peak repetitive reverse voltage sets maximum blocking capability across transformer secondary or switch node |
| trr | 35 ns - reverse recovery time directly limits minimum switching period and reduces switching loss in high-frequency converters |
| VF @ 1 A | 0.95 V max - forward voltage drop determines conduction loss and thermal load at rated current |
| RθJL | 35 °C/W - junction-to-lead thermal resistance enables direct PCB copper pour heat sinking without heatsink |
| IR @ 25°C | 5 µA max - low leakage ensures minimal standby power loss in high-impedance bias or sensing circuits |
Pinout & Package
DO-214AC (SMA) surface-mount package with cathode-indicated band; matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance; weight ≈ 0.060 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., transformer center-tap or switch source) in half-wave or full-wave configurations |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; ties to output rail or snubber capacitor; must withstand full VRRM during off-state |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enhances humidity resistance and long-term reliability under reflow and operational thermal cycling |
| Super fast trr ≤ 35 ns | Reduces reverse recovery charge (Qrr) and associated switching losses in 200–500 kHz flyback and LLC converters |
| J-STD-020 Level 1 MSL | Enables standard SMT assembly without baking or special handling prior to reflow |
| RoHS & halogen-free | Meets IEC 61249-2-21 and global environmental compliance requirements for industrial and lighting end equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR105 | VRRM = 50 V, trr = 50 ns, VF = 1.05 V @ 1 A - slower recovery and higher VF than ES1A M2G | Suitable for <100 kHz designs where Qrr impact is lower; less optimal in high-frequency snubbers | Select when legacy qualification requires ON Semi sourcing or when slightly higher VF is acceptable for cost trade-off |
| Vishay VS-1EWH05 | VRRM = 50 V, trr = 30 ns, VF = 0.92 V @ 1 A - marginally faster and lower VF, but MSL Level 2 vs. Level 1 | Better performance in >300 kHz converters; requires moisture bake if stored >168 hrs post-dry-pack opening | Prefer for highest-efficiency 500 kHz+ designs where MSL handling can be controlled in production |
Compared with MUR105 and VS-1EWH05, the ES1A M2G delivers best-in-class balance of speed (35 ns), low VF (0.95 V), and zero-moisture-risk assembly (MSL 1), making it ideal for high-volume, high-reliability industrial power supplies requiring no bake logistics.

FAQ
What is the maximum junction temperature rating for ES1A M2G?
The ES1A M2G has a maximum junction temperature (TJ) rating of +150 °C, with an operating range from –55 °C to +150 °C. This allows reliable use in enclosed industrial power supplies where ambient temperatures may exceed 85 °C. Derating curves confirm 1 A average forward current remains valid up to 115 °C case temperature, provided thermal design maintains RθJA ≤ 85 °C/W.
Is ES1A M2G compatible with lead-free reflow soldering processes?
Yes, ES1A M2G is fully compatible with lead-free reflow soldering per J-STD-002. Its matte tin-plated leads meet solderability requirements, and its DO-214AC package withstands peak reflow temperatures up to 260 °C. The device is classified MSL Level 1, meaning it can be stored indefinitely without dry packing or baking prior to assembly.
What does the "M2G" suffix indicate in ES1A M2G?
The "M2G" suffix in ES1A M2G denotes Taiwan Semiconductor's standard packaging and environmental compliance code: "M2" indicates tape-and-reel packaging (7,500 pcs/reel), and "G" signifies RoHS-compliant, halogen-free construction per IEC 61249-2-21. It is not a performance variant - all electrical specs match the base ES1A designation.
How does ES1A M2G compare to ES1B M2G in terms of voltage rating and application suitability?
ES1A M2G is rated for 50 V VRRM, while ES1B M2G is rated for 100 V VRRM - both share identical current (1 A), trr (35 ns), VF (0.95 V), and package (DO-214AC). ES1A M2G is selected for lower-voltage outputs (e.g., 5–12 V rails), whereas ES1B M2G suits 24–48 V systems. Substitution requires verifying reverse voltage margin in the target circuit.
Can ES1A M2G be used in place of a standard FR107 rectifier?
No - ES1A M2G is not a direct replacement for FR107. While both are DO-214AC devices, FR107 is a fast (not super fast) rectifier with trr ≈ 500 ns and VRRM = 1000 V. ES1A M2G offers 35 ns trr but only 50 V VRRM. Using ES1A M2G in a 1000 V circuit would cause immediate breakdown. Select ES1A M2G only where 50 V blocking and ultra-fast recovery are both required.
