Product details
Overview
ES2HA M2G from Taiwan Semiconductor is a 2A, 600V super fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 35ns reverse recovery time, 1.70V max forward voltage at 2A/25°C, and 50A peak surge current. It serves as a freewheeling or snubber diode in high-frequency switching power supplies.
For engineers reviewing the ES2HA M2G datasheet, ES2HA M2G pinout, ES2HA M2G application, or ES2HA M2G equivalent, key selection criteria include VRRM = 600V, IF = 2A, trr = 35ns, 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 thermal performance up to 150°C junction temperature and low leakage (<10µA @ 25°C, <350µA @ 125°C). Its 35ns recovery time enables efficient operation in DC-DC converters switching above 100kHz.
The device exhibits 20pF junction capacitance at 1MHz/4V and a junction-to-lead thermal resistance of 20°C/W - critical for thermal management in compact, high-density PCB layouts where lead conduction dominates heat dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports input rectification in 400V AC line-derived SMPS with safety margin |
| IF | 2 A continuous - suitable for output-stage freewheeling in ≤40W isolated flyback or buck-boost converters |
| trr | 35 ns - minimizes switching losses and EMI in high-frequency (>100 kHz) topologies |
| VF max | 1.70 V @ 2A/25°C - defines conduction loss budget; contributes ~3.4W dissipation at full load |
| RθJA | 75 °C/W - requires ≥150 mm² copper pour for safe operation at 2A in still air |
| IFSM | 50 A @ 8.3ms - withstands inrush and transient overloads without bond-wire failure |
| Junction temp | –55°C to +150°C - enables deployment in industrial ambient environments up to +85°C |
Pinout & Package
DO-214AC (SMA) surface-mount package with cathode band marking; matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to switch node or transformer secondary winding in freewheeling path |
| Cathode | Current exit point during forward conduction; marked by band | Connected to output rail or ground return; polarity must match PCB silkscreen |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures long-term reliability under humidity and thermal cycling per J-STD-020 Level 1 moisture sensitivity |
| Super fast recovery (35ns) | Reduces reverse recovery charge (Qrr) to <15nC, lowering switching loss vs. standard rectifiers |
| Low-profile SMA package | Enables ≤1.0mm board height in space-constrained lighting and adapter designs |
| Halogen-free & RoHS-compliant | Meets IEC 61249-2-21 and EU Directive 2011/65/EU for green manufacturing compliance |
Applications
| DC-DC Converter | Switching Inverter |
|---|---|
Use Scenario: Secondary-side synchronous rectification in isolated 24V-output flyback converter operating at 132kHz. IC Role / Device Role / Timing Role: Freewheeling diode conducting during MOSFET off-time; handles 2A average output current. Use Value: 35ns trr limits reverse recovery loss to <0.5W, improving efficiency by 1.2% over 100ns alternatives. | Use Scenario: Snubber network in 3-phase IGBT-based motor drive inverter (15kHz PWM). IC Role / Device Role / Timing Role: Clamp diode absorbing turn-off energy spikes across IGBT collector-emitter. Use Value: 600V VRRM and 50A IFSM ensure robust clamping without avalanche degradation. |
| LED Driver | Industrial Power Supply |
Use Scenario: Output rectification in constant-current LED driver for streetlight applications (120V AC input, 36V/0.7A output). IC Role / Device Role / Timing Role: Primary output rectifier in non-isolated buck-PFC stage. Use Value: 1.70V VF maintains >90% efficiency at full load while meeting IEC 61000-3-2 harmonic limits. | Use Scenario: Input bridge leg in 24V/5A industrial DIN-rail power supply with wide-input range (85–264V AC). IC Role / Device Role / Timing Role: High-voltage input rectifier handling 2A RMS current with 600V blocking capability. Use Value: Glass passivation and –55°C to +150°C rating support operation in unventilated enclosures at +70°C ambient. |
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 | VF = 1.75V max @ 2A; trr = 30ns; DO-214AC package | Slightly faster recovery but higher forward drop; same thermal footprint | Prefer when minimizing Qrr is critical and 50mV VF penalty is acceptable |
| MBR260 | Schottky, 60V VRRM, 1.1V VF; DO-214AC | Lower VF but insufficient voltage rating for 600V applications | Only viable in low-voltage DC-DC outputs (<48V); not a functional substitute for ES2HA M2G's 600V role |
Compared with STTH2R06 and MBR260, ES2HA M2G uniquely balances 600V blocking, 35ns recovery, and 1.70V conduction loss in a standard SMA footprint - making it optimal for universal-input SMPS where voltage margin and switching efficiency are both constrained.

FAQ
What is the maximum junction temperature rating for ES2HA M2G?
The ES2HA M2G has a maximum junction temperature (TJ) rating of +150°C, with a storage temperature range of –55°C to +150°C. This allows reliable operation in industrial environments where ambient temperatures reach +85°C, provided thermal design meets the RθJA = 75°C/W specification. Derating curves in the ES2HA M2G datasheet confirm 2A continuous current is sustainable up to 125°C case temperature under defined PCB conditions.
Does ES2HA M2G have a RoHS and halogen-free certification?
Yes, ES2HA M2G is RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21. The molding compound is UL 94V-0 rated, and terminals are matte tin-plated to meet J-STD-002 solderability requirements. These certifications are explicitly stated in the official Taiwan Semiconductor ES2HA M2G product documentation and verified on TSC's qualified materials list.
What is the reverse recovery time (trr) of ES2HA M2G and how is it measured?
The ES2HA M2G has a reverse recovery time (trr) of 35 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is specified in the Electrical Specifications table of the ES2HA M2G datasheet and confirmed by the test circuit diagram in Figure 6. It reflects the diode's ability to transition rapidly from conduction to blocking, directly impacting switching loss in high-frequency converters.
Is ES2HA M2G compatible with automated SMT placement equipment?
Yes, ES2HA M2G is explicitly designed for automated placement, as noted in its features list. Its DO-214AC (SMA) package has standardized dimensions, matte tin-plated leads, and J-STD-020 Level 1 moisture sensitivity - all enabling reliable pick-and-place, reflow soldering, and post-reflow inspection. The low-profile construction further supports high-speed placement accuracy and tombstoning resistance.
What does the "M2G" suffix indicate in ES2HA M2G?
The "M2G" suffix in ES2HA M2G denotes Taiwan Semiconductor's internal packaging and environmental compliance variant: "M2" indicates tape-and-reel packaging (7,500 units per reel), and "G" signifies halogen-free and RoHS-compliant construction. This coding aligns with TSC's ordering nomenclature documented in the ES2HA M2G datasheet Version M2102, and is distinct from voltage-grade identifiers like "AA" through "JA".
