Product details
Overview
ESH3D V7G from Taiwan Semiconductor is a 200V, 3A ultra-fast surface-mount rectifier in DO-214AB (SMC) package, featuring 20 ns reverse recovery time, 0.9 V forward voltage at 3 A, and 125 A peak surge current - deployed in high-frequency switching mode power supplies for telecom and computing infrastructure.
For engineers reviewing the ESH3D V7G datasheet, ESH3D V7G pinout, ESH3D V7G application, or ESH3D V7G equivalent, key selection criteria include repetitive peak reverse voltage (200 V), thermal resistance (12 °C/W junction-to-lead), moisture sensitivity level (J-STD-020 Level 1), RoHS/halogen-free compliance, and SMC package compatibility with automated placement.
Technical Context
The ESH3D V7G is a single-die, glass-passivated ultra-fast recovery rectifier optimized for high-efficiency DC/DC conversion where fast switching and low conduction loss are critical. Its 20 ns trr and 0.9 V VF at 3 A enable reduced switching losses in SMPS operating above 100 kHz.
Thermally, it supports operation from –55 °C to +175 °C junction temperature, with RθJL = 12 °C/W enabling direct heat transfer to PCB copper, and RθJA = 47 °C/W under standard JEDEC conditions - suitable for compact, convection-cooled designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum non-repetitive reverse blocking voltage; defines safe operating range in flyback/freewheeling paths |
| IF | 3 A continuous - average forward current rating at TL = 75 °C; determines steady-state power handling |
| trr | 20 ns - measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables >500 kHz switching without excessive turn-off loss |
| VF | 0.9 V max at IF = 3 A, TJ = 25 °C - sets conduction loss baseline; impacts thermal design at full load |
| RθJL | 12 °C/W - junction-to-lead thermal resistance; allows direct thermal coupling to PCB copper pour or heatsink tab |
| IFSM | 125 A - 8.3 ms half-sine surge rating; withstands inrush and fault currents in AC-DC front-ends |
| CJ | 45 pF at 1 MHz, VR = 4 V - influences high-frequency noise and snubber sizing in resonant topologies |
Pinout & Package
Package: DO-214AB (SMC), molded plastic case with matte tin-plated leads, cathode indicated by band, weight ≈ 0.200 g, UL 94V-0 rated compound.
| Pin/Terminal | Circuit Role | Design Meaning |

| Anode | Forward current entry point | Connected to lower-potential side of rectification path; requires adequate copper area for thermal dissipation |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; ties to output rail or switch node; must maintain clearance per 200 V working voltage |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | VRRM = 600 V, trr = 35 ns, VF = 1.15 V @ 3 A | Higher voltage rating but slower recovery and higher conduction loss | Preferred where 600 V blocking is mandatory; less efficient in 200 V-class SMPS |
| MBR3200 | Schottky structure, VF = 0.82 V @ 3 A, no reverse recovery, but VRRM = 200 V max | No reverse recovery loss, but leakage rises sharply above 100 °C (IR > 1 mA at 125 °C) | Better for low-noise, low-loss 25–100 °C ambient; unsuitable for high-temp industrial enclosures |
Compared with STTH3L06S and MBR3200, the ESH3D V7G delivers optimal balance of 200 V blocking, 20 ns speed, and 0.9 V conduction loss across –55 °C to +175 °C, making it ideal for thermally constrained telecom and server power stages where both efficiency and ruggedness are required.

FAQ
What is the maximum junction temperature rating for the ESH3D V7G?
The ESH3D V7G has a maximum junction temperature (TJ) rating of +175 °C, with a minimum of –55 °C. This wide operating range supports deployment in sealed industrial enclosures and under-hood automotive modules where ambient temperatures exceed 105 °C. The ESH3D V7G maintains specified electrical parameters across this full range when derated per its forward current derating curve.
Does the ESH3D V7G have a RoHS and halogen-free certification?
Yes, the ESH3D V7G is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound meets UL 94V-0 flammability requirements, and its matte tin-plated leads are solderable per J-STD-002. These certifications are verified in Taiwan Semiconductor's official qualification reports and apply directly to the ESH3D V7G device marking and packaging configuration.
What is the reverse recovery time (trr) test condition for the ESH3D V7G?
The ESH3D V7G reverse recovery time is specified as 20 ns maximum, measured under the conditions: IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This standardized test reflects real-world behavior during hard-switched transitions in buck, boost, and LLC converters. The ESH3D V7G achieves this value consistently due to its ultra-fast silicon process and optimized carrier lifetime control.
Is the ESH3D V7G suitable for lead-free reflow soldering?
Yes, the ESH3D V7G is qualified for lead-free reflow soldering per J-STD-020 Level 1 moisture sensitivity - meaning it can be processed without pre-bake in standard IPC/JEDEC-compliant profiles, including peak temperatures up to 260 °C. Its matte tin-plated leads ensure reliable wetting and intermetallic formation during both SnPb and Pb-free assembly.
How does the ESH3D V7G compare to the ESH3B and ESH3C variants?
The ESH3D V7G shares identical package (DO-214AB), thermal performance (RθJL = 12 °C/W), and forward characteristics (IF = 3 A, VF ≤ 0.9 V) with ESH3B and ESH3C, differing only in VRRM: 100 V (ESH3B), 150 V (ESH3C), and 200 V (ESH3D V7G). All three use the same die process and glass passivation, ensuring consistent reliability and recovery behavior across the family.
