Product details
Overview
ES1GHR3G from Taiwan Semiconductor is a 1 A, 400 V super fast recovery surface-mount rectifier diode in DO-214AC (SMA) package, featuring 35 ns reverse recovery time, 1.30 V max forward voltage at 1 A and 25°C, and 5 µA max reverse leakage at rated VR and 25°C, used in DC-DC converters and snubber circuits.
For engineers reviewing the ES1GHR3G datasheet, ES1GHR3G pinout, ES1GHR3G application, or ES1GHR3G equivalent, key selection criteria include peak repetitive reverse voltage (400 V), forward surge current capability (30 A), junction-to-lead thermal resistance (35 °C/W), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance.
Technical Context
This single-die, unidirectional silicon rectifier uses glass passivated junction technology to achieve stable performance under high-frequency switching conditions. Its super fast recovery (trr ≤ 35 ns) minimizes switching losses in high-efficiency power topologies.
The device operates across -55°C to +150°C junction temperature range with 85 °C/W junction-to-ambient thermal resistance. Cathode polarity is marked by a visible band on the DO-214AC molded case, and terminals are matte tin-plated for reliable solderability per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum repetitive reverse voltage the diode blocks without breakdown; defines usable input voltage headroom in flyback or buck-derived topologies. |
| IF | 1 A - Continuous average forward current rating; determines steady-state conduction capability in low-power SMPS outputs. |
| trr | 35 ns - Measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables operation up to ~3–5 MHz switching frequencies with minimal recovery loss. |
| VF (max) | 1.30 V @ 1 A, 25°C - Forward voltage drop directly impacts conduction loss and thermal rise in compact layouts. |
| RθJL | 35 °C/W - Junction-to-lead thermal resistance; supports direct PCB copper pad heat sinking for improved power handling without heatsinks. |
| IR (max) | 5 µA @ VR = 400 V, 25°C - Low leakage ensures minimal standby power loss in energy-sensitive applications like IoT power supplies. |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, single-anode/single-cathode configuration. Cathode indicated by molded band. Matte tin-plated leads, UL 94V-0 molding compound, 0.060 g typical weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Forward current entry point | Connected to lower-potential node (e.g., switch node in boost, ground return in freewheeling path). |
| Cathode (banded end) | Forward current exit / reverse blocking terminal | Connected to higher-potential output rail; polarity marking prevents reverse installation in automated assembly. |
Key Features
| Feature | Design Value |
|---|---|

| J-STD-020 Level 1 moisture sensitivity | Enables standard SMT reflow without dry-pack or baking requirements, lowering manufacturing cost and complexity. |
| RoHS and halogen-free compliance | Fulfills IEC 61249-2-21 and environmental regulations for consumer, industrial, and automotive-grade end equipment. |
Applications
| DC-DC Converter | Snubber Circuit |
|---|---|
Use Scenario: Secondary-side rectification in isolated 5–24 V output flyback or forward converters delivering up to 12 W. IC Role / Device Role / Timing Role: Unidirectional current steering and AC-to-DC conversion at switching node; replaces slower general-purpose rectifiers to reduce loss.

Use Value: 30 A IFSM withstands repeated 10–20 ms surges common in 24 V industrial actuators without degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR140 | Same 400 V VRRM, but 50 ns trr and 1.3 V VF; DO-41 through-hole package. | Requires PCB through-hole layout; unsuitable for fully SMT designs. | Select when legacy through-hole assembly is mandated and 15 ns slower recovery is acceptable. |
| Vishay VS-ES1GHE3/5BT | Identical DO-214AC package, 400 V, 35 ns trr, but 1.25 V VF (typ) and 10 µA IR (25°C); halogen-free, RoHS compliant. | Same footprint and function; minor VF/IR trade-off favors lower conduction loss at cost of slightly higher leakage. | Prefer for new designs where <1.25 V VF improves light-load efficiency in battery-powered systems. |
Compared with MUR140 and VS-ES1GHE3/5BT, ES1GHR3G offers optimal balance of ultra-fast recovery, SMT compatibility, and industry-standard thermal performance-making it ideal for space-constrained, high-frequency power supply designs requiring J-STD-020 Level 1 handling.

FAQ
What is the maximum junction temperature rating for ES1GHR3G?
The ES1GHR3G has a maximum junction temperature (TJ max) of +150°C, enabling reliable operation in thermally demanding environments such as enclosed LED drivers or industrial power modules. This rating is maintained across its full operating current range and supports derating curves defined in the official TSC datasheet. Thermal design should reference the 35 °C/W junction-to-lead resistance to estimate temperature rise under actual PCB copper area conditions. The ES1GHR3G must not exceed this limit during continuous or pulsed operation.
Does ES1GHR3G meet J-STD-020 moisture sensitivity requirements?
Yes, ES1GHR3G is rated at Moisture Sensitivity Level 1 per J-STD-020, meaning it can be exposed indefinitely to floor life conditions (≤30°C/85% RH) without baking prior to reflow. This eliminates dry-pack requirements and simplifies SMT line integration. The qualification is verified per TSC's internal reliability testing and documented in the ES1A–ES1J datasheet revision O2112. No special handling or storage controls are needed for ES1GHR3G beyond standard ESD-safe practices.
What is the reverse recovery time (trr) specification for ES1GHR3G?
The ES1GHR3G has a maximum reverse recovery time (trr) of 35 ns, measured under standardized conditions: IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed in the Electrical Specifications table of the TSC ES1A–ES1J datasheet. The 35 ns trr enables efficient operation in switching power supplies operating up to 500 kHz, reducing switching losses and associated EMI compared to standard fast recovery diodes. The ES1GHR3G maintains this performance across its rated temperature range.
Is ES1GHR3G RoHS and halogen-free compliant?
Yes, ES1GHR3G is fully RoHS compliant and halogen-free per IEC 61249-2-21. This compliance is explicitly stated in the Features section of the official TSC ES1A–ES1J datasheet (O2112). The molding compound, lead finish, and internal construction contain no restricted substances above threshold limits, making ES1GHR3G suitable for export to EU, China, Korea, and other regulated markets. Compliance documentation is available upon request from Aetrix Electronics for full BOM traceability.
What package type does ES1GHR3G use, and what are its mechanical identifiers?
ES1GHR3G uses the DO-214AC (SMA) surface-mount package, with cathode polarity indicated by a visible molded band on the body. Dimensions conform to JEDEC outline MO-136AA. The device weighs approximately 0.060 g, features UL 94V-0 flammability-rated epoxy, and uses matte tin-plated leads qualified per J-STD-002 for solderability. The marking "ES1G" appears on the banded side, confirming the 400 V variant within the ES1x family. No alternate packages exist for ES1GHR3G.
