Product details
Overview
ES3J R7G 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. It serves as a primary output rectifier in high-frequency SMPS for telecom power supplies.
For engineers reviewing the ES3J R7G datasheet, ES3J R7G pinout, ES3J R7G application, or ES3J R7G equivalent, key selection criteria include VRRM = 600V, IF = 3A, trr = 35ns, thermal resistance RθJA = 47°C/W, and DO-214AB mechanical compatibility with automated SMT lines.
Technical Context
This single-die silicon rectifier uses glass-passivated junction technology to achieve stable high-voltage blocking and rapid carrier recombination. Its 35ns reverse recovery time enables operation in switching converters above 100kHz without excessive switching loss or EMI generation.
The device operates across -55°C to +150°C junction temperature range with 12°C/W junction-to-lead thermal resistance, supporting high-power-density designs where lead-frame conduction dominates heat dissipation over PCB copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports DC bus voltages up to 424V RMS in bridge configurations |
| IF | 3 A continuous - delivers full rated current at TA ≤ 75°C with standard PCB layout |
| trr | 35 ns - enables efficient operation in 100–500 kHz SMPS topologies with low diode switching loss |
| VF max | 1.70 V @ 3A, 25°C - contributes ≤5.1W conduction loss at full load, critical for thermal budgeting |
| RθJA | 47 °C/W - requires ≥1.5 cm² of 2-oz copper pad for safe 3A operation at 70°C ambient |
| IFSM | 100 A @ 8.3ms - withstands inrush and transient surges common in AC-DC front-end stages |
| CJ | 30 pF @ 1MHz, 4V - minimizes capacitive coupling noise in high-dv/dt gate-drive or snubber circuits |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, cathode-indicated by molded band, matte tin-plated leads compliant with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |

| Cathode | Current exit terminal during forward conduction | Connected to output rail or filter capacitor positive; marked by visible band on body |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures long-term reliability under humidity stress and prevents leakage drift in industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-ES3JHM3/5A | VRRM = 600V, trr = 35ns, but RθJA = 55°C/W (vs. 47°C/W for ES3J R7G) | Higher thermal resistance requires larger copper area or forced air in space-constrained OBCs | Prefer ES3J R7G when board area is limited and thermal headroom is tight |
| ON Semiconductor MUR360RLG | VRRM = 600V, trr = 50ns (vs. 35ns), VF = 1.85V max (vs. 1.70V) | Slower recovery increases switching loss in >200kHz designs; higher VF raises conduction loss | Acceptable for cost-sensitive 100kHz telecom adapters where 15ns trr margin is non-critical |
Compared with VS-ES3JHM3/5A and MUR360RLG, ES3J R7G offers superior thermal performance and lowest trr/VF combination in the 3A/600V class, making it optimal for high-efficiency, high-power-density SMPS where thermal and switching losses must be minimized simultaneously.

FAQ
What is the maximum junction temperature rating for ES3J R7G?
The ES3J R7G has a maximum junction temperature (TJ) of +150°C and a minimum of -55°C. This wide operating range allows deployment in harsh environments such as enclosed server PSUs or under-hood automotive applications. Derating curves in the ES3J R7G datasheet define usable current versus ambient temperature, with full 3A capability maintained up to 75°C ambient using standard PCB copper.
Is ES3J R7G RoHS and halogen-free compliant?
Yes, ES3J R7G is fully RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and the matte tin-plated leads satisfy J-STD-002 solderability requirements. These certifications are verified in Taiwan Semiconductor's official compliance documentation for the ES3x family.
What does the 'R7G' suffix indicate in ES3J R7G?
The 'R7G' suffix in ES3J R7G denotes tape-and-reel packaging: R7 = 3,000 units per reel, G = green compound (halogen-free). This matches Taiwan Semiconductor's ordering code convention defined in the ES3x datasheet revision N2102, where 'ES3x' is the base part and suffixes specify packaging and material variants.
Can ES3J R7G replace ES3H R7G in an existing design?
Yes, ES3J R7G can directly replace ES3H R7G because both share identical DO-214AB (SMC) package, pinout, and thermal characteristics, differing only in VRRM (600V vs. 500V) and VF (1.70V vs. 1.70V max). The higher voltage rating provides additional margin in systems exposed to line transients or operating near 400V DC-link rails.
What is the reverse recovery time test condition for ES3J R7G?
The reverse recovery time (trr) of 35ns for ES3J R7G is measured under standardized conditions: IF = 0.5A, IR = 1.0A, Irr = 0.25A, per JEDEC test method. This reflects real-world behavior during hard-switching transitions in SMPS, and is confirmed across production lots in Taiwan Semiconductor's qualification reports for the ES3x series.
