Product details
Overview
ES15JLW from Taiwan Semiconductor is a 600 V, 1.5 A super fast surface-mount rectifier in SOD-123W package, featuring 35 ns reverse recovery time, 1.18 V forward voltage at 1.5 A/25°C, and 20 pF junction capacitance. It serves as a freewheeling or output rectifier in high-frequency switching power supplies.
For engineers reviewing the ES15JLW datasheet, ES15JLW pinout, ES15JLW application, or ES15JLW equivalent, key selection criteria include peak reverse voltage rating, forward voltage trade-off at elevated temperature, thermal resistance (RθJA = 76°C/W), and compatibility with automated SMT assembly on standard PCB pads.
Technical Context
The ES15JLW employs a single-die silicon PN junction with glass passivation for stable reverse leakage and robust surge handling. Its 600 V VRRM rating enables use in 400 V DC bus systems with margin, while the 35 ns trr supports operation up to ~3 MHz in hard-switched topologies.
Thermal performance is defined for mounting on a 5 mm × 5 mm copper pad: RθJL = 26°C/W and RθJC = 27°C/W confirm low thermal impedance to lead and case, supporting 1.5 A continuous conduction without forced cooling under typical ambient conditions.
Key Specifications

| VRRM | 600 V - Supports 400 V nominal DC bus with 50% safety margin against transients |
| IF | 1.5 A continuous - Rated for sustained conduction in compact SMT layouts |
| trr | 35 ns max - Enables efficient operation in SMPS above 500 kHz with low switching loss |
| VF | 1.18 V @ 1.5 A, 25°C - Directly impacts conduction loss and thermal rise in high-duty-cycle apps |
| CJ | 20 pF @ 4 V - Limits capacitive coupling noise and EMI in high-dv/dt environments |
| RθJA | 76°C/W - Defines maximum power dissipation (≈1.97 W) before exceeding 150°C junction limit |
| IFSM | 40 A @ 8.3 ms - Withstands brief inrush or fault currents without bond-wire failure |

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 A IF, 50 ns trr, DO-214AA package | Lower current rating and slower recovery; larger footprint | Acceptable where board space allows and peak load current ≤1 A |
| MBR1560CT | 60 V VRRM, dual common-cathode Schottky, TO-220AC package | Not suitable for 400 V bus; incompatible voltage class and thermal interface | Only viable in low-voltage (<100 V) high-efficiency applications requiring Schottky VF |
Compared with STTH1L06S and MBR1560CT, the ES15JLW delivers higher current capability in a miniature SMT package with faster recovery-making it optimal for space-constrained, high-frequency 400 V systems where thermal management relies on PCB copper area rather than heatsinks.

FAQ
What is the maximum junction temperature rating for ES15JLW?
The ES15JLW has a maximum junction temperature (TJMAX) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating applies under continuous operation with proper PCB thermal design-specifically, mounting on a 5 mm × 5 mm copper pad. Exceeding this temperature risks irreversible degradation of the glass-passivated junction. Derating curves in the ES15JLW datasheet show usable current drops to ~0.9 A at 125°C ambient with standard layout.
Does ES15JLW have a specified reverse recovery time (trr)?
Yes, the ES15JLW specifies a maximum reverse recovery time (trr) of 35 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is measured per JEDEC standards and confirmed across production lots. The 35 ns trr directly enables efficient operation in switching power supplies operating above 500 kHz, distinguishing ES15JLW from standard recovery rectifiers.
What is the forward voltage (VF) of ES15JLW at full rated current?
At IF = 1.5 A and TJ = 25°C, the ES15JLW exhibits a typical forward voltage of 1.18 V and a maximum of 1.70 V. At elevated junction temperature (125°C), VF decreases to 0.97 V typical and 1.30 V maximum. These values are measured per the electrical specifications table in the ES15JLW datasheet and reflect actual conduction loss under real operating conditions.
Is ES15JLW compatible with lead-free reflow soldering processes?
Yes, ES15JLW is fully compatible with lead-free reflow soldering. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the SOD-123W package is rated for peak reflow temperatures up to 260°C. The device carries J-STD-020 Moisture Sensitivity Level 1, meaning it can be placed directly onto the board without pre-baking-even after extended dry-pack storage.
What does the "J" in ES15JLW signify?
The "J" in ES15JLW is the voltage grade code assigned by Taiwan Semiconductor, uniquely identifying this variant as the 600 V version within the ES15xLW family. Per the ordering information table, "x" maps to D = 200 V, G = 400 V, and J = 600 V. This code appears as the cathode-band marking "ES15J" on the physical ES15JLW device and must be verified visually during incoming inspection.
