Product details
Overview
ES3BHR7G from Taiwan Semiconductor is a 3A, 100V super fast recovery surface-mount rectifier in DO-214AB (SMC) package, featuring 35ns reverse recovery time, 0.95V forward voltage at 3A/25°C, and 100A peak surge current - used in high-frequency freewheeling and SMPS output stages.
For engineers reviewing the ES3BHR7G datasheet, ES3BHR7G pinout, ES3BHR7G application, or ES3BHR7G equivalent, key selection criteria include VRRM = 100 V, IF = 3 A, trr = 35 ns, thermal resistance RθJA = 47 °C/W, and DO-214AB mechanical compatibility with automated SMT assembly.
Technical Context
This single-die silicon rectifier employs glass-passivated junction technology to achieve stable switching performance under repetitive surge conditions. Its 35 ns reverse recovery time and low 0.95 V forward voltage at rated current support high-efficiency operation in 100 kHz–1 MHz DC-DC converters and flyback snubbers.
The device operates across –55°C to +150°C junction temperature range with JESD201 Class 2 whisker resistance and moisture sensitivity level 1 (J-STD-020), enabling reliable reflow soldering and long-term thermal cycling in industrial power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum non-repetitive reverse blocking voltage; defines safe operating margin in 48 V output rails |
| IF | 3 A continuous - average forward current rating at TL = 75°C; supports 36 W conduction loss budget in 12 V–48 V outputs |
| trr | 35 ns - measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables <100 kHz–1 MHz switching without excessive switching loss |
| VF | 0.95 V @ 3 A, 25°C - low conduction drop reduces thermal load in compact SMC footprint |
| RθJA | 47 °C/W - junction-to-ambient thermal resistance; requires ≥100 mm² copper pour for full 3 A derating at 75°C ambient |
| IFSM | 100 A @ 8.3 ms - withstands inrush and fault currents in offline AC-DC front ends and motor drive clamps |
Pinout & Package
DO-214AB (SMC) package: molded epoxy case meeting UL 94V-0, matte tin-plated leads, cathode indicated by band, weight ≈ 0.210 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter or transformer secondary center-tap) |
| Cathode | Forward current exit / reverse blocking terminal | Connected to output rail; polarity band identifies this terminal for correct PCB orientation |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable leakage and recovery characteristics over temperature and lifetime, critical for 150°C-rated operation |
| Super fast 35 ns trr | Reduces reverse recovery charge (Qrr) to <15 nC, minimizing EMI and diode-induced switching losses in hard-switched topologies |
| Moisture sensitivity level 1 | Eliminates bake requirement before reflow, supporting standard J-STD-020-compliant SMT line throughput |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for green electronics manufacturing |

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-3EWH10-M3/5AT | VRRM = 100 V, trr = 30 ns, VF = 0.92 V @ 3 A - slightly faster but same package and rating | Same DO-214AB footprint; optimized for higher-frequency flyback in consumer adapters | Preferred where sub-30 ns trr is required and Vishay sourcing is preferred |
| ON Semiconductor MUR310EG | VRRM = 100 V, trr = 50 ns, VF = 0.97 V @ 3 A - slower recovery, higher VF, same SMC package | Designed for general-purpose SMPS; less suitable for >500 kHz designs due to Qrr penalty | Select when cost sensitivity outweighs efficiency targets and layout reuse is mandatory |
Compared with VS-3EWH10-M3/5AT and MUR310EG, ES3BHR7G delivers balanced performance: 35 ns trr enables efficient 300–800 kHz operation, 0.95 V VF limits conduction loss, and Taiwan Semiconductor's green compound meets strict halogen-free requirements without trade-offs in surge robustness.

FAQ
What is the maximum junction temperature rating for ES3BHR7G?
The ES3BHR7G has a maximum junction temperature (TJ) rating of +150°C and a minimum storage temperature of –55°C. This rating is validated per absolute maximum ratings table in the official Taiwan Semiconductor datasheet N2102, enabling operation in high-ambient environments such as enclosed server PSUs and industrial motor drives where heatsinking is limited.
Does ES3BHR7G have a halogen-free construction?
Yes, ES3BHR7G is halogen-free in accordance with IEC 61249-2-21 and RoHS compliant. The molding compound uses green formulation without brominated flame retardants, confirmed in the "Features" section of the N2102 datasheet - critical for compliance in EU and Asian electronics markets.
What is the reverse recovery time (trr) test condition for ES3BHR7G?
The reverse recovery time of 35 ns for ES3BHR7G is measured under the condition: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, per the Electrical Specifications table in the N2102 datasheet. This standardized test ensures reproducible comparison across super fast rectifier families.
Is ES3BHR7G compatible with lead-free reflow soldering profiles?
Yes, ES3BHR7G supports lead-free reflow soldering per J-STD-020. Its moisture sensitivity level is rated Level 1, meaning it can be stored indefinitely at ≤30°C/60% RH and placed directly into standard Pb-free reflow without baking - verified in the Mechanical Data section of the N2102 datasheet.
What does the 'HR7G' suffix indicate in ES3BHR7G?
The 'HR7G' suffix in ES3BHR7G denotes Taiwan Semiconductor's internal packaging and environmental coding: 'H' = halogen-free, 'R7' = tape-and-reel packaging (3,000 pcs/reel), and 'G' = green compound. This matches the ordering code convention defined in the N2102 datasheet's Ordering Information section.
