Product details
Overview
ES3GHR7G from Taiwan Semiconductor is a 400 V, 3 A super fast recovery surface-mount rectifier in DO-214AB (SMC) package, featuring 35 ns reverse recovery time, 1.30 V max forward voltage at 3 A and 25°C, and 30 pF junction capacitance at 1 MHz/4 V - deployed in high-frequency switching mode power supplies for telecom infrastructure.
For engineers reviewing the ES3GHR7G datasheet, ES3GHR7G pinout, ES3GHR7G application, or ES3GHR7G equivalent, key selection criteria include repetitive peak reverse voltage (400 V), thermal resistance (RθJL = 12 °C/W), moisture sensitivity level (MSL 1), RoHS/halogen-free compliance, and SMC package compatibility with automated placement.
Technical Context
This device implements a single-die, glass-passivated PN junction optimized for high-efficiency rectification in DC-DC converters and freewheeling paths. Its 35 ns trr enables operation at frequencies up to several hundred kHz without excessive switching losses.
The DO-214AB (SMC) package provides low thermal resistance (RθJL = 12 °C/W) and robust mechanical reliability, with matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - supports input rectification in 28 V–48 V telecom offline SMPS with safety margin against line transients |
| IF | 3 A continuous - sustains steady-state output current in mid-power adapters and POL modules |
| trr | 35 ns - enables efficient operation at ≥200 kHz switching frequency with minimal reverse recovery loss |
| VF max | 1.30 V @ 3 A, 25°C - limits conduction loss to ≤3.9 W per diode in high-current paths |
| CJ | 30 pF @ 1 MHz, 4 V - reduces capacitive coupling noise in high-dv/dt gate-drive or snubber circuits |
| RθJL | 12 °C/W - allows direct PCB copper pour heatsinking without external heatsink in ≤3 W dissipation designs |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, cathode-indicated by band, matte tin-plated leads, UL 94V-0 molding compound, MSL 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to lower-potential node (e.g., switch node in buck freewheel path) |
| Cathode | Current exit point during forward conduction; polarity-marked terminal | Connected to output rail or higher-potential reference; critical for correct orientation in layout |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable leakage current (<500 µA @ 100°C) and long-term reliability under thermal cycling |
| Super fast recovery (35 ns) | Reduces reverse recovery charge (Qrr) to <15 nC, minimizing EMI and cross-conduction risk in synchronous topologies |
| MSL 1 rating | Eliminates bake-out requirement before reflow, supporting standard SMT assembly without process modification |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally regulated end equipment |
Applications
| Telecom AC-DC Front-End Rectification | Server VRM Freewheeling Diode |
|---|---|
Use Scenario: Input stage of 48 V telecom rectifier supplying distributed power architecture. IC Role / Device Role / Timing Role: Primary rectifier converting AC line to bulk DC, handling 3 A average current at 400 V PIV. Use Value: Low VF (1.30 V max) minimizes conduction loss; 35 ns trr prevents efficiency drop at 300 kHz PFC switching. | Use Scenario: Freewheeling path in multiphase buck converter powering CPU/GPU core rails. IC Role / Device Role / Timing Role: Unidirectional current path during low-side FET off-time, clamping inductive kickback. Use Value: 30 pF CJ reduces dv/dt-induced gate noise; RθJL = 12 °C/W enables direct thermal coupling to PCB ground plane. |

IC Role / Device Role / Timing Role: High-reliability output rectifier operating continuously at 85°C ambient. Use Value: 150°C TJMAX and MSL 1 ensure long life in sealed enclosures; halogen-free construction meets industrial environmental specs. | Use Scenario: Compact 5 V/3 A buck-derived supply for image sensor and ISP in rear-view camera. IC Role / Device Role / Timing Role: Synchronous rectifier replacement where cost-sensitive design avoids driver complexity. Use Value: DO-214AB footprint fits tight board space; 0.210 g weight avoids mechanical stress on flex PCB interconnects. |
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-ES3GHE3/54 | VRRM = 400 V, trr = 35 ns, VF = 1.30 V max - identical electrical specs; same DO-214AB package but different marking and tape/reel orientation | No functional difference in rectification role; validated in same telecom SMPS reference designs | Drop-in alternative if dual-sourcing required; verify reel packaging compatibility with pick-and-place feeders |
| ON Semiconductor MUR340G | VRRM = 400 V, trr = 50 ns (slower), VF = 1.25 V max - higher Qrr, slightly lower conduction loss | Acceptable in ≤150 kHz designs; may increase EMI in >200 kHz telecom converters due to longer trr | Preferable where lower VF dominates over speed; not recommended for high-frequency PFC stages |
Compared with VS-ES3GHE3/54, ES3GHR7G offers identical performance and fit; versus MUR340G, ES3GHR7G delivers faster recovery (35 ns vs. 50 ns) enabling higher-frequency operation with lower switching loss, though at marginally higher forward voltage.

FAQ
What is the maximum junction temperature rating for ES3GHR7G?
The ES3GHR7G has a maximum junction temperature (TJMAX) of +150°C, allowing reliable operation in enclosed industrial or telecom power supplies where ambient temperatures reach 85–105°C. This rating is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor ES3A–ES3J datasheet (Version N2102), and applies directly to ES3GHR7G as a member of the ES3G variant group.
Does ES3GHR7G meet RoHS and halogen-free requirements?
Yes, ES3GHR7G is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the Taiwan Semiconductor ES3A–ES3J datasheet (Version N2102). The device uses halogen-free molding compound and meets all substance restrictions defined in EU Directive 2011/65/EU, making it suitable for environmentally regulated end equipment including telecom and industrial systems.
What is the reverse recovery time (trr) of ES3GHR7G and under what test conditions?
The ES3GHR7G 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, as specified in the ELECTRICAL SPECIFICATIONS table of the Taiwan Semiconductor ES3A–ES3J datasheet (Version N2102). This value is consistent across the ES3F–ES3J subgroup, confirming its suitability for high-frequency switching applications.
Is ES3GHR7G compatible with standard SMT reflow processes without baking?
Yes, ES3GHR7G carries Moisture Sensitivity Level (MSL) 1 per J-STD-020, meaning it can be stored indefinitely at ≤30°C/60% RH and placed directly into standard lead-free reflow profiles without pre-bake. This eliminates process steps and reduces manufacturing risk - a key advantage confirmed in the FEATURES section of the Taiwan Semiconductor ES3A–ES3J datasheet (Version N2102).
What package type and marking does ES3GHR7G use?
ES3GHR7G uses the DO-214AB (SMC) surface-mount package with cathode polarity indicated by a band. Its marking code is "ES3G", followed by "H" (halogen-free), "R7" (date code), and "G" (green compound), consistent with Taiwan Semiconductor's ordering convention for the ES3x family as documented in the ORDERING INFORMATION section of Version N2102.
