Product details
Overview
ES3JHR7G from Taiwan Semiconductor is a 3A, 600V super fast recovery surface-mount rectifier in DO-214AB (SMC) package, featuring 35ns reverse recovery time, 1.70V max forward voltage at 3A/25°C, and 100A peak surge current - deployed in high-frequency switching mode power supplies for telecom infrastructure.
For engineers reviewing the ES3JHR7G datasheet, ES3JHR7G pinout, ES3JHR7G application, or ES3JHR7G equivalent, key selection criteria include VRRM = 600V, IF = 3A, trr = 35ns, RθJA = 47°C/W, and DO-214AB mechanical compatibility with automated SMT assembly lines.
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, ≤500µA @ 100°C). Its 35ns recovery time enables efficient operation in 100–500kHz SMPS topologies.
The device exhibits 30pF junction capacitance at 1MHz/4V reverse bias and a junction-to-lead thermal resistance of 12°C/W - critical for thermal management in compact, high-power-density DC/DC converters where lead-frame conduction dominates heat dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports input rectification in 400VAC mains-derived systems with safety margin |
| IF | 3 A continuous - delivers rated output current in 36–75W isolated flyback or forward converters |
| trr | 35 ns - minimizes switching losses and EMI in high-frequency hard-switched topologies |
| VF (max) | 1.70 V @ 3A/25°C - determines conduction loss and thermal load under full-load conditions |
| RθJA | 47 °C/W - defines maximum ambient temperature rise for PCB-mounted operation without heatsink |
| CJ | 30 pF @ 1MHz/4V - impacts high-frequency noise coupling and snubber design in resonant circuits |
| IFSM | 100 A @ 8.3ms - withstands inrush currents during cold-start of AC-DC front-ends |
Pinout & Package
DO-214AB (SMC) surface-mount package with matte tin-plated leads, polarity indicated by cathode band, UL 94V-0 molding compound, and JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to transformer secondary or switch node; requires low-inductance layout to limit voltage overshoot |
| Cathode | Current exit point during forward conduction | Connected to output capacitor or common return; cathode band marks this terminal on body |
Key Features

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-ES3JHM3 | VF = 1.75V (max), trr = 35ns, same DO-214AB package, MSL Level 1 | Identical electrical envelope but slightly higher VF; validated in Vishay's 500kHz LLC reference designs | Preferred where Vishay qualification documentation is required for automotive-grade programs |
| ON Semiconductor MUR360RLG | VRRM = 600V, IF = 3A, trr = 50ns, VF = 1.85V (max), DO-201AD package | Larger DO-201AD footprint; 15ns slower recovery increases switching loss in >250kHz designs | Acceptable for cost-sensitive industrial PSUs where board space allows larger package and frequency < 200kHz |
Compared with VS-ES3JHM3 and MUR360RLG, ES3JHR7G offers identical trr and lower VF than MUR360RLG while maintaining the smallest footprint (DO-214AB), making it optimal for space-constrained, high-frequency telecom and server power supplies.

FAQ
What is the maximum junction temperature rating for ES3JHR7G?
The ES3JHR7G has a maximum junction temperature (TJMAX) of +150°C, verified per absolute maximum ratings table in Taiwan Semiconductor's N2102 datasheet. This rating applies across the full operating current range and enables reliable use in thermally constrained environments such as sealed telecom modules. Derating curves confirm 3A continuous current is maintainable up to 100°C ambient when mounted on standard FR-4 PCB with 1-inch² copper pour.
Does ES3JHR7G have a halogen-free construction?
Yes, ES3JHR7G is halogen-free in accordance with IEC 61249-2-21 and RoHS-compliant per EU Directive 2011/65/EU. The molding compound contains no brominated flame retardants or chlorine-based additives, and all plating meets JEDEC J-STD-020 moisture sensitivity level 1 requirements - confirmed in the "Mechanical Data" section of the official ES3A–ES3J datasheet (Version N2102).
What is the reverse recovery time specification for ES3JHR7G?
The ES3JHR7G reverse recovery time (trr) is specified as 35ns maximum under test conditions of IF = 0.5A, IR = 1.0A, and Irr = 0.25A. This value is measured per JEDEC standard and appears in the "Electrical Specifications" table of the N2102 datasheet. It reflects consistent super-fast switching behavior across the ES3H–ES3J voltage grades.
Is ES3JHR7G suitable for use in automotive applications?
No, ES3JHR7G is not qualified for automotive applications. Taiwan Semiconductor explicitly states in the "Notice" section of the N2102 datasheet that ES3A–ES3J products are "not designed for use in medical, life-saving, or life-sustaining applications," and no AEC-Q101 stress test data or automotive-specific qualification is provided for ES3JHR7G. It is intended for industrial, telecom, and computing power systems only.
What packaging format is available for ES3JHR7G?
ES3JHR7G is supplied in tape-and-reel packaging with 3,000 units per reel, conforming to the DO-214AB (SMC) package outline defined in the "Ordering Information" section of the N2102 datasheet. The reel complies with EIA-481-D standards and supports high-speed automated placement using standard SMT feeders calibrated for 8mm carrier tape width and 4mm pocket depth.
