Product details
Overview
ES1GLWH from Taiwan Semiconductor is a 1A, 400V super fast surface-mount rectifier diode in SOD-123W 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 high-frequency DC-DC converters and LED lighting drivers.
For engineers reviewing the ES1GLWH datasheet, ES1GLWH pinout, ES1GLWH application, or ES1GLWH equivalent, key selection criteria include its 400V VRRM, 30A IFSM, 175°C maximum junction temperature, SOD-123W low-profile footprint, and verified AEC-Q101 compliance for under-hood automotive use.
Technical Context
The ES1GLWH employs a glass-passivated silicon junction optimized for fast switching with minimal stored charge, enabling efficient operation in 100–500 kHz DC-DC topologies. Its 35ns trr and 20pF junction capacitance support reduced switching losses and EMI in compact power stages.
Thermally, it delivers RθJL = 25°C/W and RθJA = 80°C/W in standard PCB mounting, allowing 1A continuous conduction up to 125°C ambient when properly heatsinked via leads. Moisture sensitivity level 1 ensures compatibility with standard reflow processes without baking.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L04W | Same SOD-123W package; 400V VRRM, 1.25V VF (max), 30ns trr; not AEC-Q101 qualified | Preferred for industrial non-automotive DC-DC where qualification isn't required | Select STTH1L04W for cost-sensitive non-automotive designs needing marginally faster recovery |
| ON Semi MUR120SFT1G | SOD-123 package (not W variant); 200V VRRM, 1.15V VF, 35ns trr; AEC-Q101 qualified | Limited to ≤200V circuits; smaller thermal pad area reduces RθJL margin | Choose MUR120SFT1G only if system voltage is strictly ≤200V and board space allows tighter pitch |
Compared with STTH1L04W and MUR120SFT1G, the ES1GLWH uniquely combines AEC-Q101 qualification, 400V rating, and SOD-123W's enhanced thermal pad-making it the only option validated for 400V automotive snubbers requiring both reliability and thermal headroom.

FAQ
What is the maximum junction temperature rating for ES1GLWH?
The ES1GLWH has a maximum junction temperature (TJ(max)) of +175°C, verified per AEC-Q101 stress testing. This rating allows reliable operation in under-hood automotive environments where ambient temperatures exceed 125°C. Derating curves in the ES1GLWH datasheet confirm 1A continuous current is sustainable up to 125°C ambient with standard PCB copper area. Thermal design must account for RθJL = 25°C/W to avoid exceeding this limit.
Is ES1GLWH pin-compatible with ES1DLWH or ES1JLWH?
Yes - ES1GLWH shares identical SOD-123W package dimensions, pinout, and solder pad layout with ES1DLWH (200V) and ES1JLWH (600V). All three use the same anode/cathode terminal configuration and cathode band marking. However, forward voltage and reverse recovery differ: ES1GLWH specifies 1.30V VF and 35ns trr, while ES1DLWH is 0.95V/35ns and ES1JLWH is 1.70V/35ns. System voltage rating must match the selected variant.
Does ES1GLWH require pre-baking before reflow soldering?
No - ES1GLWH is rated moisture sensitivity level (MSL) 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH and placed directly into standard lead-free reflow profiles without pre-baking. This eliminates process steps and risk of moisture-induced popcorning, supporting high-yield automated assembly in automotive electronics manufacturing.
What is the reverse leakage current specification for ES1GLWH at elevated temperature?
Per the ES1GLWH datasheet, reverse leakage current (IR) is ≤5 µA at 25°C and rated VR, rising to ≤100 µA at 125°C and same voltage. This behavior is consistent across the ES1xLWH family and reflects controlled leakage in the glass-passivated junction. At 175°C junction temperature, leakage remains within safe operational limits for snubber and freewheeling functions.
Can ES1GLWH replace a standard FR107 in an existing design?
ES1GLWH is not a direct replacement for FR107 due to fundamental differences: FR107 is a through-hole DO-41 device rated 1000V/1A with ~500ns trr, while ES1GLWH is SOD-123W, 400V/1A, and 35ns trr. Substitution would require PCB redesign for surface-mount layout, voltage derating, and thermal validation. For SMD upgrades, consider ES1GLWH only where 400V blocking and fast recovery are explicitly needed - not as generic FR107 drop-in.
