Product details
Overview
ES2G-13-F from Diodes Incorporated is a 2.0A surface-mount super-fast rectifier diode in SMB package, rated for 400V peak repetitive reverse voltage, 35ns reverse recovery time, and 1.25V forward voltage at 2.0A - deployed in high-frequency switch-mode power supplies and AC/DC adapters requiring fast switching and low conduction loss.
For engineers reviewing the ES2G-13-F datasheet, ES2G-13-F pinout, ES2G-13-F application, or ES2G-13-F equivalent, key selection criteria include reverse recovery time (35 ns), thermal resistance (20 °C/W), surge rating (50 A), RoHS-compliant lead-free finish, and SMB package compatibility with automated SMT assembly.
Technical Context
This super-fast rectifier uses glass-passivated silicon die to achieve rapid carrier recombination, enabling efficient operation in 50–500 kHz SMPS topologies. Its 35 ns trr and low 25 pF junction capacitance minimize switching losses and EMI generation during turn-off transitions.
The device operates across –55°C to +150°C with a 20 °C/W junction-to-terminal thermal resistance when mounted on 5.0 mm² copper pads. It sustains 50 A non-repetitive surge current under 8.3 ms half-sine conditions, supporting robust input rectification in transient-prone mains interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum peak reverse voltage before breakdown; defines safe operating limit in bridge or output rectifier positions. |
| IO @ TT=110°C | 2.0 A - Continuous average forward current derated to terminal temperature; enables compact layout without forced cooling. |
| trr | 35 ns - Measured at IF=0.5A, IR=1.0A, Irr=0.25A; ensures minimal reverse recovery charge in high-frequency converters. |
| VFM @ IF=2.0A | 1.25 V - Forward voltage drop at rated DC load; determines conduction loss and thermal dissipation in rectifier stage. |
| RθJT | 20 °C/W - Junction-to-terminal thermal resistance with 5.0 mm² copper pad; guides PCB copper area design for thermal management. |
| IFSM (8.3 ms) | 50 A - Non-repetitive surge capability; withstands inrush currents in AC-input stages without failure. |
| CT @ 1 MHz, 4 V | 25 pF - Junction capacitance at low reverse bias; impacts high-frequency noise coupling and snubber design. |
Pinout & Package
Package: SMB (Surface Mount Body), molded plastic case per UL 94V-0, with cathode band polarity marking and matte tin-plated terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry node during forward conduction | Connected to AC source or transformer secondary; must handle full load current and surge transients. |
| Cathode | Current exit node during forward conduction; marked with band | Routes rectified current to filter capacitor or DC bus; polarity critical for correct circuit operation. |
Key Features
| Feature | Design Value |
|---|---|
| Super-fast recovery time | 35 ns trr enables >200 kHz switching in PFC and secondary-side rectification without excessive loss. |
| Glass passivated die | Enhances reliability and moisture resistance versus epoxy-passivated alternatives; supports long-term stability in humid environments. |
| Lead-free / RoHS compliant | Matte tin plating meets EU Directive 2002/95/EC; compatible with Pb-free reflow profiles and industrial environmental requirements. |
| Green molding compound | Halogen- and antimony-free polymer reduces toxic emissions during PCB rework or end-of-life disposal. |
| 50 A surge rating | Withstands cold-start inrush and lightning-induced surges in offline power supplies without degradation. |
Applications
| AC/DC Adapter Input Rectification | Switch-Mode Power Supply Output Stage |
|---|---|
Use Scenario: Converts 50/60 Hz AC mains to pulsating DC prior to bulk filtering in wall-wart adapters. IC Role / Device Role / Timing Role: Primary rectifier diode in single-phase bridge or voltage-doubler configuration. Use Value: 400 V VRRM and 50 A IFSM ensure reliable operation under line surges and universal input (90–264 VAC). | Use Scenario: Freewheeling or synchronous rectification in isolated DC-DC converters (e.g., flyback, forward). IC Role / Device Role / Timing Role: Secondary-side unidirectional current path with minimal reverse recovery loss. Use Value: 35 ns trr and 25 pF CT reduce switching noise and improve efficiency above 100 kHz. |
| Industrial Motor Drive Front-End | LED Driver Bulk Rectification |
Use Scenario: Rectifies three-phase or single-phase AC input feeding DC bus capacitors in variable frequency drives. IC Role / Device Role / Timing Role: High-current, high-reliability input rectifier subjected to frequent overloads and thermal cycling. Use Value: 2.0 A IO at 110°C TT and –55°C to +150°C operating range support harsh factory-floor environments. | Use Scenario: Converts AC line to DC for constant-current LED driver ICs in commercial lighting fixtures. IC Role / Device Role / Timing Role: Mains-side rectifier in non-isolated buck or buck-boost LED drivers. Use Value: Low 1.25 V VFM minimizes heat generation in thermally constrained enclosed luminaires. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06S | Same 2.0A/600V rating but 50 ns trr; higher VF (1.7 V @ 2A); TO-277 package | Higher thermal mass but larger footprint; less suitable for ultra-thin adapters | Prefer when higher voltage margin (600 V) is required and board space allows TO-277 mounting. |
| MBR240SFT1G | Schottky type; 40 V VRRM, 0.52 V VF, no reverse recovery; SMB package | Only suitable for low-voltage DC-DC outputs, not AC line rectification | Select only for <60 V DC applications where zero trr and ultra-low VF outweigh voltage limitation. |
Compared with STTH2R06S and MBR240SFT1G, ES2G-13-F uniquely balances 400 V blocking, 35 ns speed, SMB footprint, and 2.0 A current in a RoHS/Green-compliant construction - making it optimal for space-constrained, high-efficiency AC/DC front-ends.

FAQ
What is the maximum junction temperature for ES2G-13-F?
The ES2G-13-F has an operating junction temperature range of –55°C to +150°C. Its thermal design relies on junction-to-terminal resistance (20 °C/W) with specified PCB copper pad area (5.0 mm²). Derating begins at terminal temperatures above 110°C, where average forward current drops to 2.0 A.
Is ES2G-13-F suitable for use in a PFC boost diode position?
No - ES2G-13-F is not recommended for active PFC boost diodes due to its 400 V VRRM rating and lack of soft-recovery characteristics. PFC stages typically require ≥600 V rating and optimized soft-recovery or SiC Schottky diodes to manage high dv/dt and reverse recovery stress.
Does ES2G-13-F have a halogen-free construction?
Yes - ES2G-13-F uses green molding compound certified halogen- and antimony-free per IEC 61249-2-21, applicable to devices manufactured from week 24, 2009 onward (data code 0924+), as confirmed in Diodes' DS30212 Rev. 8–2.
How is polarity identified on the ES2G-13-F SMB package?
Polarity is indicated by a cathode band (visible ink mark) on the body end of the SMB package. The terminal adjacent to the band is the cathode; the opposite end is the anode. This matches standard SMB diode orientation and aligns with PCB silkscreen and footprint markings.
