Product details
Overview
ES3GH from Taiwan Semiconductor is a 400V, 3A super fast recovery surface-mount rectifier in DO-214AB (SMC) package, featuring 35ns reverse recovery time, 1.30V max forward voltage at 3A/25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or snubber diode in high-frequency DC-DC converters and LED lighting drivers.
For engineers reviewing the ES3GH datasheet, ES3GH pinout, ES3GH application, or ES3GH equivalent, key selection criteria include its 400V repetitive peak reverse voltage, 100A surge rating, junction-to-lead thermal resistance of 12°C/W, moisture sensitivity level 1 compliance, and RoHS/halogen-free status per IEC 61249-2-21.
Technical Context
The ES3GH operates as a single-die, unidirectional silicon rectifier with glass-passivated junction for enhanced reliability under thermal cycling and humidity stress. Its super fast recovery (trr ≤ 35 ns) enables efficient operation in switching frequencies up to several hundred kHz, minimizing switching losses in flyback and buck-derived topologies.
Designed for automotive and industrial environments, the ES3GH supports continuous operation from –55°C to +150°C junction temperature, with 10µA max reverse leakage at 25°C and 500µA at 100°C, and exhibits 30pF junction capacitance at 1MHz/4V reverse bias - critical for EMI-sensitive snubber and clamping circuits.

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-ES3GHE3/5BT | Same DO-214AB package, 400V VRRM, 1.35V VF max @ 3A, trr = 35ns, AEC-Q101 qualified | Identical automotive qualification and thermal specs; slightly higher VF increases conduction loss by ~0.15W at 3A | Preferred where Vishay supply chain alignment or dual-sourcing is required; no layout change needed |
| ON Semiconductor MUR340RLG | DO-214AC (SMA) package, 400V VRRM, 1.30V VF max @ 3A, trr = 50ns, not AEC-Q101 qualified | Higher trr increases switching loss and EMI; smaller SMA package limits thermal performance (RθJA ≈ 75°C/W vs 47°C/W) | Suitable for cost-sensitive non-automotive industrial designs where board space is constrained and thermal margin exists |
Compared with VS-ES3GHE3/5BT, ES3GH offers identical electrical specs and qualification but different marking and tape/reel packaging; versus MUR340RLG, ES3GH delivers superior thermal management and automotive reliability at same voltage/current rating - critical for under-hood deployment.

Manufacturer
Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, specializing in power rectifiers, TVS diodes, and MOSFETs for automotive and industrial markets.
The ES3AH–ES3JH series was developed to deliver AEC-Q101-qualified super fast rectifiers with optimized trr/CJ trade-offs across 50–600V ratings, targeting high-efficiency, high-reliability power conversion in space-constrained automotive and industrial systems.
FAQ
What is the maximum junction temperature rating for ES3GH?
The ES3GH has a maximum junction temperature (TJ MAX) of +150°C, verified per absolute maximum ratings table in the official TSC datasheet Version A2102. This rating allows continuous operation in under-hood automotive environments and high-ambient industrial enclosures. Derating curves confirm usable current capacity down to –55°C storage temperature, and thermal impedance data supports thermal design using RθJL = 12°C/W for lead-to-PCB heat transfer. The ES3GH must be mounted on adequate copper area to maintain TJ ≤ 150°C at full 3A load.
Is ES3GH pin-compatible with ES3FH or ES3HH?
Yes, ES3GH shares identical DO-214AB (SMC) package dimensions, pinout, and mechanical footprint with all members of the ES3AH–ES3JH family, including ES3FH and ES3HH. All variants use the same anode/cathode terminal configuration and cathode band polarity marking. However, electrical parameters differ: ES3FH is rated for 300V VRRM, ES3GH for 400V, and ES3HH for 500V - so voltage rating must be verified per application. The ES3GH cannot substitute for ES3FH in 300V-only designs without overrating margin review.
Does ES3GH meet automotive qualification standards?
Yes, ES3GH is explicitly AEC-Q101 qualified per the TSC datasheet Version A2102, covering stress tests including high-temperature operating life (HTOL), temperature cycling (TC), unbiased highly accelerated stress test (UHAST), and electrostatic discharge (HBM). This qualification confirms suitability for automotive powertrain, body electronics, and lighting applications. The ES3GH also meets J-STD-020 moisture sensitivity level 1 and JESD201 class 2 whisker resistance - all documented in the mechanical and reliability sections of the ES3GH datasheet.
What is the reverse recovery time (trr) specification for ES3GH?
The ES3GH has a maximum reverse recovery time (trr) of 35 ns, measured under conditions IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as specified in the Electrical Specifications table of the TSC datasheet. This value is confirmed for the entire ES3FH–ES3JH subgroup (400–600V variants). The 35 ns trr enables high-frequency switching in DC-DC converters up to 500 kHz while limiting reverse recovery charge (Qrr) to approximately 12–14 nC - directly reducing switching losses and EMI compared to standard fast recovery diodes.
Can ES3GH be used as a replacement for a standard FR304 rectifier?
No, ES3GH is not a direct replacement for FR304. While both are 3A rectifiers, FR304 is a standard recovery diode with trr ≈ 500 ns and VRRM = 400 V, whereas ES3GH is a super fast device with trr ≤ 35 ns - offering significantly lower switching loss and EMI. Substituting ES3GH for FR304 requires verifying layout parasitics, snubber adjustments, and gate drive strength, as faster recovery may increase voltage spikes if circuit inductance is unmitigated. The ES3GH is optimized for high-frequency designs; using it in legacy 50/60 Hz applications adds unnecessary cost without benefit.
