Product details
Overview
ESJLWH from Taiwan Semiconductor is a 600V, 0.8A super fast surface-mount rectifier in SOD-123W package, featuring 35ns reverse recovery time, 1.14V typical forward voltage at 0.8A/25°C, and AEC-Q101 qualification for automotive use in snubber and freewheeling circuits.
For engineers reviewing the ESJLWH datasheet, ESJLWH pinout, ESJLWH application, or ESJLWH equivalent, key selection criteria include peak reverse voltage (600V), thermal resistance (RθJA = 88°C/W), junction capacitance (19pF), and compliance with JESD201 Class 2 whisker testing and RoHS/Halogen-free standards.
Technical Context
The ESJLWH is a single-die, glass-passivated silicon PN junction rectifier optimized for high-speed switching in DC-DC converters and automotive lighting. Its 600V VRRM, 20A IFSM, and 150°C maximum junction temperature support robust operation under transient overloads and elevated ambient conditions.
Thermal performance is defined with RθJL = 34°C/W and RθJC = 35°C/W on a 5mm × 5mm Cu pad PCB, enabling reliable power dissipation in space-constrained layouts. The device exhibits low leakage (≤150µA at 125°C) and stable VF across temperature-0.94V typical at 0.8A/125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse blocking voltage; defines safe operating range in high-voltage snubber or flyback clamp circuits. |
| IF | 0.8 A - Continuous forward current rating; supports sustained conduction in automotive LED drivers and DC-DC output stages. |
| trr | 35 ns - Reverse recovery time; enables efficient high-frequency switching up to ~3 MHz without excessive switching loss. |
| VF @ 0.8A, 25°C | 1.14 V (typ), 1.70 V (max) - Forward voltage drop directly impacts conduction loss and thermal design margin. |
| CJ @ 1MHz, 4V | 19 pF - Junction capacitance affects high-frequency noise coupling and EMI in fast-switching topologies. |
| RθJA | 88 °C/W - Junction-to-ambient thermal resistance on standard PCB; determines required copper area for thermal management. |
| IR @ 125°C | ≤150 µA - Reverse leakage at max operating temperature; critical for low-power standby and precision bias networks. |
Pinout & Package
Package: SOD-123W - Low-profile, surface-mount plastic package with matte tin-plated leads, UL 94V-0 molding compound, and cathode band polarity marking. Weight: 0.016g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH0.8L06S | Same SOD-123W package, 600V VRRM, but 30ns trr and 1.10V VF @ 0.8A/25°C; no AEC-Q101 claim. | Acceptable in industrial DC-DC converters; not certified for automotive safety-critical functions. | Select when AEC-Q101 is not required and faster trr is prioritized over qualification status. |
| MBR0560 | Schottky architecture, 60V VRRM, 0.5A IF, 0.55V VF; incompatible voltage rating and current capability. | Only suitable for low-voltage, low-current applications like USB PD or portable electronics-not a functional substitute. | Reject for ESJLWH replacement; insufficient VRRM and IF for automotive or industrial 600V systems. |
Compared with STTH0.8L06S and MBR0560, ESJLWH uniquely combines AEC-Q101 qualification, 600V blocking, and 0.8A rating in SOD-123W-making it the only viable option for automotive snubbers and freewheeling where both reliability and voltage margin are mandatory.

FAQ
What is the peak repetitive reverse voltage rating of the ESJLWH?
The ESJLWH has a peak repetitive reverse voltage (VRRM) rating of 600 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version A2103). It defines the maximum reverse-biased voltage the device can block repeatedly without breakdown, making ESJLWH suitable for high-voltage snubber and flyback applications in automotive systems.
Is the ESJLWH qualified for automotive applications?
Yes, the ESJLWH 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 mechanical shock-ensuring reliability in automotive under-hood and cabin environments. ESJLWH is used in automotive LED lighting and HVAC blower circuits.
What is the forward voltage of ESJLWH at 0.8A and 25°C?
The ESJLWH exhibits a typical forward voltage (VF) of 1.14 V at 0.8A and 25°C, with a maximum of 1.70 V under the same conditions. These values are specified in the ELECTRICAL SPECIFICATIONS table for ESJLWH in the official datasheet. At 125°C, VF drops to 0.94 V (typ), reflecting the negative temperature coefficient of silicon PN junctions.
What package does the ESJLWH use, and what are its key mechanical properties?
The ESJLWH uses the SOD-123W package-a low-profile, surface-mount outline with matte tin-plated leads, UL 94V-0 flammability-rated molding compound, and cathode band polarity marking. Its weight is approximately 0.016 g. The package meets JESD201 Class 2 whisker testing and is rated MSL Level 1, eliminating pre-reflow baking requirements.
What is the reverse recovery time (trr) of ESJLWH, and how is it measured?
The ESJLWH has a maximum reverse recovery time (trr) of 35 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as specified in the ELECTRICAL SPECIFICATIONS table. This parameter reflects the time required for the device to transition from forward conduction to reverse blocking, directly impacting switching efficiency in high-frequency DC-DC converters.
