Product details
Overview
ES2HA from Taiwan Semiconductor is a 2A, 600V super fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 1.70V max forward voltage at 2A/25°C, 35ns reverse recovery time, and 20pF junction capacitance - deployed in snubber networks and DC-DC converter freewheeling paths.
For engineers reviewing the ES2HA datasheet, ES2HA pinout, ES2HA application, or ES2HA equivalent, key selection criteria include peak reverse voltage rating (600V), thermal resistance (RθJL = 20°C/W), moisture sensitivity level (MSL 1), and RoHS/halogen-free compliance for high-reliability power conversion designs.
Technical Context
This single-die silicon rectifier uses glass-passivated junction technology to achieve super-fast switching performance with low stored charge. Its 35ns trr and 1.70V VF balance conduction loss and switching loss in high-frequency SMPS topologies.
The DO-214AC (SMA) package supports automated placement and provides 75°C/W junction-to-ambient thermal resistance. Polarity is marked by cathode band; terminals are matte tin-plated per J-STD-002 solderability standard.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse blocking voltage without breakdown |
| IF | 2 A - continuous average forward current at TL = 75°C |
| IFSM | 50 A - non-repetitive surge current capability (8.3ms half-sine) |
| trr | 35 ns - reverse recovery time under IF = 0.5A, IR = 1.0A, Irr = 0.25A |
| VF | 1.70 V max - forward voltage drop at 2A and 25°C, defining conduction loss |
| CJ | 20 pF - junction capacitance at 1 MHz and 4.0V reverse bias, affecting high-frequency noise |
| RθJL | 20 °C/W - thermal resistance from junction to lead, critical for PCB copper pad design |
Pinout & Package
DO-214AC (SMA) surface-mount package with axial lead configuration: anode and cathode terminals formed as flat, coplanar leads extending from opposite ends of the molded body; polarity indicated by cathode band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of rectified path; must handle full load current and surge |
| Cathode | Forward current exit / reverse-blocking terminal | Marked by band; connects to output rail or switching node; withstands full VRRM |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable 600V blocking and long-term reliability under thermal cycling |
| Super fast recovery (35ns) | Reduces switching losses and EMI in 100–500 kHz DC-DC converters |
| MSL Level 1 rating | Allows unlimited floor life and reflow without baking prior to assembly |
| RoHS & halogen-free | Meets IEC 61249-2-21 and global environmental compliance requirements |
| Low-profile SMA package | Enables compact board layout with 2.5mm height constraint for space-constrained modules |
Applications
| DC-DC Converter Output Rectification | Snubber Network Clamp Diode |
|---|---|
Use Scenario: Secondary-side synchronous or diode rectification in isolated flyback or forward converters operating at 200–500 kHz. IC Role / Device Role / Timing Role: Freewheeling rectifier conducting during transformer reset phase; blocks reverse voltage during primary switch on-time. Use Value: 600V VRRM accommodates reflected voltage spikes; 35ns trr minimizes dead-time losses and ringing. | Use Scenario: RCD snubber across MOSFET drain-source in hard-switched PFC or LLC resonant stages. IC Role / Device Role / Timing Role: Clamp diode that conducts only during voltage overshoot events, absorbing energy from leakage inductance. Use Value: 50A IFSM handles transient surges; 1.70V VF limits clamp loss during short-duration conduction. |
| Lighting Ballast Freewheeling | Switching Inverter Freewheel Path |
Use Scenario: LED driver ballasts using high-frequency AC-DC conversion with inductive energy storage. IC Role / Device Role / Timing Role: Provides unidirectional current path during inductor discharge between switching cycles. Use Value: 2A IF rating matches typical LED string currents; MSL 1 enables direct SMT integration into lighting modules. | Use Scenario: Three-phase motor inverters or UPS systems where IGBTs require bidirectional freewheeling paths. IC Role / Device Role / Timing Role: Conducts inductive current when main switch turns off, preventing voltage runaway. Use Value: 20°C/W RθJL allows direct thermal coupling to heatsink via PCB copper; 150°C TJMAX supports high ambient operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-ES2H-M3/5BT | Same DO-214AC package, 600V VRRM, but 1.55V max VF at 2A/25°C and 50ns trr | Higher conduction efficiency but slower recovery increases switching loss above 250 kHz | Prefer for lower-loss, lower-frequency (<200 kHz) applications where thermal margin is constrained |
| ON Semiconductor MUR260RLG | DO-204AL (DO-41) through-hole package, 600V VRRM, 1.7V VF, 60ns trr | Not surface-mountable; larger footprint and higher RθJA limits power density | Select only if legacy through-hole assembly or manual repair is required; not suitable for automated SMT lines |
Compared with VS-ES2H-M3/5BT and MUR260RLG, the ES2HA delivers superior high-frequency performance (35ns vs. ≥50ns) in a fully automated SMT package while maintaining identical 600V/2A ratings - making it optimal for modern compact, high-efficiency DC-DC and lighting modules.

FAQ
What is the maximum junction temperature rating for ES2HA?
The ES2HA has a maximum junction temperature (TJ) rating of +150°C, with a storage temperature range of –55°C to +150°C. This rating enables reliable operation in high-ambient environments such as enclosed LED drivers or industrial power supplies. Thermal design must ensure junction temperature remains below this limit under worst-case load and ambient conditions. The ES2HA's RθJL of 20°C/W supports effective heat transfer to the PCB copper plane.
Does ES2HA have a specified moisture sensitivity level (MSL)?
Yes, the ES2HA is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and can be placed directly onto the PCB without pre-baking. This eliminates moisture-related popcorning risk during reflow and simplifies SMT line logistics. The device's DO-214AC (SMA) molding compound meets UL 94V-0 flammability standards and supports J-STD-002-compliant solderability.
What is the reverse recovery time (trr) specification for ES2HA?
The ES2HA has a maximum reverse recovery time (trr) of 35 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed in the official Taiwan Semiconductor datasheet (Version M2102). The fast trr reduces switching losses and improves efficiency in high-frequency converters - a key differentiator versus standard fast recovery diodes with trr > 50 ns.
Is ES2HA RoHS and halogen-free compliant?
Yes, the ES2HA is RoHS compliant and halogen-free per IEC 61249-2-21. This compliance is explicitly stated in the manufacturer's documentation and verified through material declarations. The device uses environmentally compliant molding compounds and matte tin-plated leads, supporting green manufacturing requirements for consumer, industrial, and automotive-qualified power designs.
What does the marking code 'ES2HA' indicate on the device body?
The marking code 'ES2HA' laser-etched on the ES2HA device body identifies the exact part variant within the ES2xx family: 'ES' denotes super fast rectifier, '2' indicates 2A rating, 'H' specifies 500V VRRM, and 'A' confirms the standard version (not 'B' for enhanced surge or other variants). Per the datasheet, ES2HA corresponds to 600V VRRM, confirming 'H' maps to the 600V grade in this series' coding scheme.
