Product details
Overview
ES1GH from Taiwan Semiconductor is a 1A, 400V super fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 35ns reverse recovery time, 1.30V max forward voltage at 1A/25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or snubber diode in DC-DC converters and car lighting systems.
For engineers reviewing the ES1GH datasheet, ES1GH pinout, ES1GH application, or ES1GH equivalent, key selection criteria include its 400V VRRM, 30A IFSM, 150°C TJ rating, glass-passivated junction, and J-STD-020 Level 1 moisture sensitivity - all critical for high-efficiency, thermally constrained automotive and industrial power designs.
Technical Context
The ES1GH employs a single-die silicon PN junction with glass passivation for enhanced reliability and humidity resistance. Its super-fast trr of ≤35ns enables high-frequency switching operation in flyback and buck-derived topologies without excessive switching loss.
Thermally, it delivers RθJL = 35°C/W and RθJA = 85°C/W in standard PCB mounting, supporting continuous 1A conduction up to 125°C ambient when properly heatsinked. The DO-214AC (SMA) package provides robust solderability with matte tin-plated leads compliant to J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 350–400V DC bus applications. |
| IF | 1 A - Continuous average forward current; supports compact layout in space-constrained automotive modules. |
| trr | ≤35 ns - Reverse recovery time; enables efficient operation at ≥100 kHz switching frequencies with low turn-off loss. |
| VF @ 1A, 25°C | ≤1.30 V - Forward voltage drop; determines conduction loss and thermal rise in high-duty-cycle freewheeling paths. |
| IR @ 400V, 25°C | ≤5 µA - Reverse leakage current; ensures minimal standby power loss in battery-sensitive systems. |
| TJ max | +150 °C - Maximum junction temperature; allows operation in under-hood environments without derating below 125°C ambient. |
| CJ @ 1MHz, 4V | 18 pF - Junction capacitance; impacts high-frequency noise coupling and EMI filter design in SMPS inputs. |
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, 0.060g typical weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter); must handle 30A surge during transient events. |
| Cathode (K) | Forward current exit / reverse blocking terminal | Connected to higher-potential rail (e.g., output capacitor positive); withstands 400V reverse bias continuously. |
Key Features
| Feature | Design Value |

| Glass passivated junction | Provides hermetic protection against moisture ingress and contamination, improving long-term reliability in humid or chemically aggressive under-hood environments. |
| Super fast 35ns trr | Reduces switching loss and ringing in high-frequency DC-DC stages, directly improving efficiency over standard fast recovery diodes (trr > 50ns). |
| J-STD-020 Level 1 MSL | Allows unlimited floor life before reflow; eliminates bake requirements and simplifies SMT line integration for high-volume automotive manufacturing. |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU - required for global OEM compliance and end-of-life recycling mandates. |
Applications
| Automotive LED Headlamp Driver | Industrial DC-DC Buck Converter |
|---|---|
Use Scenario: High-brightness LED array powered via constant-current buck regulator with synchronous rectification. IC Role / Device Role / Timing Role: Freewheeling diode during low-side switch off-time, clamping inductive kickback and sustaining current continuity. Use Value: 35ns trr minimizes reverse recovery charge (Qrr) and associated losses, enabling >92% efficiency at 250kHz switching while maintaining AEC-Q101 compliance. | Use Scenario: 24V-to-5V isolated DC-DC module for PLC I/O power supply in factory automation. IC Role / Device Role / Timing Role: Output rectifier in secondary-side synchronous or quasi-resonant topology, handling 1A continuous load with transient surges. Use Value: 400V VRRM provides 2× safety margin over 24V input-referred reflected voltage, and 150°C TJ rating ensures stable operation in enclosed enclosures up to 70°C ambient. |
| Snubber Network in Motor Drive Inverter | USB-C PD Adapter Secondary Rectification |
Use Scenario: RC snubber across IGBT collector-emitter to suppress voltage spikes during turn-off in 3-phase BLDC drive. IC Role / Device Role / Timing Role: Fast-clamping diode in snubber path, conducting transient energy into capacitor during nanosecond-scale voltage overshoot events. Use Value: ≤35ns trr and low CJ (18pF) ensure rapid response to dV/dt transients >500V/ns without oscillation or false triggering. | Use Scenario: Secondary-side rectification in 65W USB-C Power Delivery adapter using active clamp flyback architecture. IC Role / Device Role / Timing Role: High-efficiency output rectifier replacing Schottky diode where 400V blocking and low leakage are required for universal AC input. Use Value: 5µA max IR at 25°C reduces no-load standby power, and 1.30V VF balances conduction loss vs. cost versus higher-VF alternatives like ES1HH. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R04 | Same 1A/400V rating, but 50ns trr; higher VF (1.35V typ); TO-220AC package. | Requires through-hole mounting and larger board area; less suitable for automated SMT lines. | Select STTH1R04 only if legacy through-hole compatibility or higher surge robustness (IFSM = 50A) is prioritized over footprint and speed. |
| MBR140SFT3G | 1A/40V Schottky; 0.55V VF; no reverse recovery (trr ≈ 0ns); but VRRM too low for 400V applications. | Only viable in low-voltage outputs (<40V); unsuitable for primary-side or high-reflected-voltage secondary rectification. | Choose MBR140SFT3G only for ≤40V DC-DC outputs where ultra-low VF outweighs voltage limitation. |
Compared with STTH1R04 and MBR140SFT3G, the ES1GH uniquely combines 400V blocking, 35ns recovery, DO-214AC SMT packaging, and AEC-Q101 qualification - making it the only drop-in solution for automotive-grade, space-constrained, high-frequency 1A rectification where both voltage headroom and speed matter.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for ES1GH?
The ES1GH has a VRRM of 400 V, verified per Taiwan Semiconductor's official datasheet revision B2112. This rating defines the highest continuous reverse voltage the device can block without breakdown. It is strictly tested and guaranteed across the full operating temperature range (−55°C to +150°C) and applies to all units marked "ES1G" on the cathode band.
Is ES1GH qualified for automotive applications?
Yes, ES1GH is AEC-Q101 qualified, as explicitly stated in the manufacturer's datasheet. This qualification covers stress tests including high-temperature operating life (HTOL), temperature cycling (TC), high-temperature reverse bias (HTRB), and unbiased highly accelerated stress test (UHAST). The qualification applies specifically to the ES1GH variant, not the entire ES1xH family generically.
What is the forward voltage (VF) of ES1GH at 1A and 25°C?
The ES1GH exhibits a maximum forward voltage of 1.30 V at 1A forward current and 25°C junction temperature, per the Electrical Specifications table in the official datasheet. This value is measured under pulsed conditions (PW = 0.3ms) and represents the worst-case conduction loss for thermal design calculations in continuous-duty applications.
Does ES1GH have a specified reverse recovery time (trr)?
Yes, ES1GH has a maximum reverse recovery time of 35 ns, measured at IF = 0.5A, IR = 1.0A, and Irr = 0.25A. This parameter is confirmed in the Electrical Specifications section of the Taiwan Semiconductor datasheet and is consistent across all ES1FH–ES1JH variants due to shared die construction and process.
What package type does ES1GH use, and is it RoHS compliant?
ES1GH uses the DO-214AC (SMA) surface-mount package with matte tin-plated leads and UL 94V-0 molding compound. It is fully RoHS compliant and halogen-free per IEC 61249-2-21, as documented in the Mechanical Data and Features sections of the official datasheet. The marking code "ES1G" appears on the cathode band.
