Product details
Overview
ES1JLWH from Taiwan Semiconductor is a 1 A, 600 V super fast surface-mount rectifier diode in SOD-123W package, featuring 35 ns reverse recovery time, 1.70 V max forward voltage at 1 A and 25°C, and AEC-Q101 qualification for automotive use in snubber and freewheeling circuits.
For engineers reviewing the ES1JLWH datasheet, ES1JLWH pinout, ES1JLWH application, or ES1JLWH equivalent, key selection criteria include peak reverse voltage rating (600 V), ultra-fast recovery (≤35 ns), thermal resistance (RθJA = 80 °C/W), junction temperature range (–55 to +175 °C), and SOD-123W low-profile packaging for high-density DC/DC converter layouts.
Technical Context
The ES1JLWH employs a glass-passivated single-die silicon junction optimized for high-efficiency switching in automotive and industrial power supplies. Its 600 V VRRM, 30 A IFSM, and 1.70 V VF (max) at 1 A define its capability in high-voltage flyback and boost stages.
With RθJL = 25 °C/W and RθJA = 80 °C/W, the device supports sustained 1 A conduction under constrained thermal conditions. The 20 pF junction capacitance at 4 V and 1 MHz enables stable high-frequency operation in snubber networks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06S | 600 V VRRM, 1.05 V VF (typ), 50 ns trr, DO-214AC package | Larger footprint; higher thermal mass but lower conduction loss | Preferred where board space allows and lower VF outweighs speed penalty |
| MBR160L | 60 V VRRM, Schottky, 0.52 V VF, no reverse recovery | Not suitable for >100 V blocking; limited to low-voltage DC/DC | Only viable for sub-60 V systems; not a functional replacement for ES1JLWH's 600 V role |
Compared with STTH1L06S, ES1JLWH offers faster recovery (35 vs. 50 ns) and smaller SOD-123W footprint, trading 0.65 V higher VF for superior high-frequency performance. MBRL160L cannot replace ES1JLWH due to 90% lower VRRM, making it unsuitable for 400–600 V applications.

FAQ
What is the maximum repetitive peak reverse voltage rating for ES1JLWH?
The ES1JLWH has a maximum repetitive peak reverse voltage (VRRM) of 600 V. This rating is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version B2110). It defines the highest reverse voltage the ES1JLWH can block repeatedly without breakdown under normal operating conditions, making it suitable for 400–600 V bus applications such as automotive DC/DC converters and industrial snubbers.
Is ES1JLWH qualified for automotive applications?
Yes, ES1JLWH is AEC-Q101 qualified, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD), confirming suitability for automotive power electronics such as LED headlamp drivers and engine control unit DC/DC supplies where reliability under harsh thermal and electrical conditions is required.
What is the forward voltage drop of ES1JLWH at 1 A and 25°C?
The ES1JLWH exhibits a maximum forward voltage (VF) of 1.70 V at 1 A and 25°C, per the Electrical Specifications table. This value represents the worst-case conduction loss under nominal conditions and directly impacts thermal design-dissipating up to 1.7 W at full current. The typical VF is lower, but system-level thermal analysis must use the 1.70 V maximum to ensure safe junction temperature margins.
What package type does ES1JLWH use, and what are its key mechanical attributes?
ES1JLWH uses the SOD-123W surface-mount package, specified in the MECHANICAL DATA section. Key attributes include a low profile (≤0.9 mm height), matte tin-plated solderable leads compliant with J-STD-002, UL 94V-0 flammability rating, polarity indicated by cathode band, and moisture sensitivity level 1 (no bake required before reflow). Its compact size supports high-density PCB layouts in space-constrained automotive modules.
What is the reverse recovery time (trr) of ES1JLWH, and how does it impact switching performance?
The ES1JLWH has a reverse recovery time (trr) of 35 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This ultra-fast recovery minimizes switching losses and voltage overshoot in high-frequency power converters (e.g., 300–500 kHz DC/DC stages), enabling higher efficiency and reduced EMI compared to standard fast rectifiers with trr > 50 ns. The 35 ns value is confirmed in the Electrical Specifications table of the official datasheet.
