Product details
Overview
ES3DHR7G from Taiwan Semiconductor is a 3A, 200V super fast recovery surface-mount rectifier in DO-214AB (SMC) package, featuring 35ns reverse recovery time, 0.95V max forward voltage at 3A/25°C, and 100A peak surge current - used in high-frequency switching mode power supplies for telecom and computing.
For engineers reviewing the ES3DHR7G datasheet, ES3DHR7G pinout, ES3DHR7G application, or ES3DHR7G equivalent, key selection criteria include VRRM=200V, IF=3A, trr≤35ns, thermal resistance RθJA=47°C/W, and DO-214AB mechanical compatibility with automated SMT assembly.
Technical Context
This single-die, unidirectional silicon rectifier uses glass-passivated junction technology to achieve stable performance across -55°C to +150°C junction temperature range. Its super-fast recovery enables efficient operation in DC-DC converters and freewheeling paths where low switching loss and minimal reverse recovery charge are critical.
The device is rated for 100A non-repetitive surge (8.3ms half-sine) and exhibits low junction capacitance (45pF at 1MHz/4V), supporting high-frequency rectification up to several hundred kHz without excessive capacitive loading or ringing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in bridge or flyback clamp circuits |
| IF | 3 A continuous - Average forward current rating at TL=75°C; determines heatsink-free operation in compact SMPS designs |
| trr | 35 ns - Reverse recovery time at IF=0.5A, IR=1.0A, Irr=0.25A; enables >200 kHz switching with low diode switching loss |
| VF max | 0.95 V at 3A/25°C - Forward voltage drop directly impacts conduction loss and thermal rise in high-current output rectifiers |
| RθJA | 47 °C/W - Junction-to-ambient thermal resistance; used to calculate temperature rise under PCB copper area constraints |
| CJ | 45 pF at 1 MHz, 4 V - Junction capacitance affects high-frequency noise coupling and EMI filter design in SMPS outputs |
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 |

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-3EJH02-M3/5BT | VRRM=200V, trr=35ns, but IF=3.0A avg and VF=0.92V @ 3A - slightly lower forward drop | Same DO-214AB footprint; identical thermal profile but tighter VF distribution | Preferred when minimizing conduction loss is prioritized over cost |
| ON Semiconductor MUR320RLG | VRRM=200V, trr=35ns, IF=3.0A, but VF=1.05V @ 3A and RθJA=50°C/W - higher conduction loss and thermal resistance | Compatible in layout but requires marginally larger copper pour for same thermal rise | Selected when second-source qualification mandates ON Semi portfolio alignment |
Compared with VS-3EJH02-M3/5BT and MUR320RLG, ES3DHR7G offers balanced trade-offs: identical trr and VRRM, competitive VF, superior RθJA (47 vs. 50°C/W), and J-STD-020 Level 1 moisture rating - making it optimal for high-volume, thermally constrained SMT production.

FAQ
What is the maximum junction temperature rating for ES3DHR7G?
The ES3DHR7G has a maximum junction temperature (TJ) of +150°C and a minimum of –55°C. This wide operating range allows reliable use in enclosed industrial environments and high-ambient telecom equipment. Derating curves in the official TSC datasheet show usable current decreases linearly above 75°C lead temperature, ensuring predictable thermal behavior in real-world PCB layouts.
Is ES3DHR7G compatible with lead-free reflow soldering processes?
Yes, ES3DHR7G supports lead-free reflow per J-STD-020. Its matte tin-plated leads are rated for peak temperatures up to 260°C, and its moisture sensitivity level is Level 1 - meaning no baking or dry-pack requirements before assembly. The DO-214AB package maintains mechanical integrity through standard IPC/JEDEC profiles, including ramp rates up to 3°C/s and 60-second dwell above 217°C.
Does ES3DHR7G have a specified reverse recovery charge (Qrr) value?
No Qrr value is published in the TSC ES3x datasheet for ES3DHR7G. Only trr = 35 ns (max) is specified under defined test conditions (IF=0.5A, IR=1.0A, Irr=0.25A). Designers requiring Qrr should consult TSC's application note AN-107 or perform bench measurement using standardized double-pulse test setups, as Qrr varies significantly with operating temperature and di/dt.
Can ES3DHR7G be used as a direct replacement for ES3D in existing designs?
Yes, ES3DHR7G is a direct replacement for ES3D - both share identical electrical specifications (VRRM=200V, IF=3A, trr≤35ns), DO-214AB package, and marking code "ES3D". The "HR7G" suffix denotes green, halogen-free, RoHS-compliant packaging per IEC 61249-2-21, with no functional or thermal performance change versus legacy ES3D.
What is the typical junction-to-lead thermal resistance (RθJL) for ES3DHR7G?
The typical junction-to-lead thermal resistance (RθJL) for ES3DHR7G is 12°C/W, measured under standard JEDEC test conditions. This parameter is critical for estimating die temperature when using external heatsinking via PCB copper pads or thermal vias - especially in high-current, high-ambient applications like 48V telecom rectifiers where lead temperature can be directly monitored.
