Product details
Overview
HS1JLW from Taiwan Semiconductor is a 1 A, 600 V high-efficiency surface-mount silicon rectifier diode in SOD-123W package, with forward voltage of 1.7 V at 1 A and junction capacitance of 16 pF at 1 MHz / 4.0 V reverse bias, used in DC-DC converters and freewheeling paths.
For engineers reviewing the HS1JLW datasheet, HS1JLW pinout, HS1JLW application, or HS1JLW equivalent, key selection criteria include peak reverse voltage (600 V), thermal resistance (RθJL = 25 °C/W), reverse recovery time (75 ns), and SOD-123W footprint compatibility with automated placement.
Technical Context
The HS1JLW is a single-die, glass-passivated PN-junction rectifier optimized for switching-mode power supplies. Its 600 V VRRM, 75 ns trr, and 16 pF CJ support high-frequency operation up to ~1 MHz under 4.0 V reverse bias.
Designed for low-loss freewheeling and output rectification, it operates across -55°C to +175°C junction temperature range and delivers 30 A non-repetitive surge current capability with RθJA = 80 °C/W in still air.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse blocking voltage; defines safe operating limit in flyback or boost output stages |
| IF | 1 A continuous - rated average forward current; supports compact thermal design in space-constrained DC-DC modules |
| VF | 1.7 V max @ 1 A, 25°C - forward conduction loss directly impacts efficiency in high-duty-cycle rectification |
| trr | 75 ns max - fast recovery reduces switching losses and EMI in 100–500 kHz SMPS designs |
| CJ | 16 pF @ 1 MHz, 4.0 V - junction capacitance affects high-frequency noise coupling and snubber sizing |
| RθJL | 25 °C/W - low junction-to-lead thermal resistance enables direct PCB copper pour heat sinking without heatsinks |
Pinout & Package
Package: SOD-123W - low-profile, surface-mount plastic case with matte tin-plated leads, UL 94V-0 molding compound, cathode band polarity marking, and JESD201 Class 2 whisker resistance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR160 | 600 V VRRM, 1 A IF, 60 ns trr, DO-41 package (through-hole) | Requires PCB through-hole mounting; higher RθJA (~65 °C/W) limits power density | Select when legacy through-hole assembly or higher surge robustness (50 A IFSM) is prioritized over board space |
| Vishay VS-1EWH06 | 600 V VRRM, 1 A IF, 70 ns trr, SOD-123FL package (0.6 mm height) | Slightly lower profile but same SOD-123 footprint; 1.85 V VF increases conduction loss | Select when minimal height (<0.65 mm) is mandatory and 0.15 V higher VF is acceptable for thermal budget |
Compared with MUR160 and VS-1EWH06, the HS1JLW offers the best balance of SMD compatibility, 16 pF CJ for high-frequency stability, and 25 °C/W RθJL for direct copper thermal transfer-making it optimal for dense, thermally constrained DC-DC modules.

FAQ
What is the maximum junction temperature rating for the HS1JLW?
The HS1JLW has a maximum junction temperature (TJMAX) of +175°C, enabling reliable operation in high-ambient environments such as industrial motor drives and automotive under-hood power supplies. This rating is validated per JEDEC standards and allows derating curves to be applied for continuous 1 A operation up to 85°C ambient with appropriate PCB copper area. The HS1JLW maintains specified electrical parameters within this full temperature range.
Does the HS1JLW support automated pick-and-place assembly?
Yes, the HS1JLW uses the SOD-123W package with matte tin-plated leads compliant with J-STD-002 solderability requirements and moisture sensitivity level 1 per J-STD-020-making it fully compatible with standard SMT reflow and high-speed automated placement equipment. Its low-profile geometry and consistent marking (HJLW) further ensure high-yield placement accuracy in volume manufacturing of power modules.
What is the reverse recovery time (trr) specification for the HS1JLW?
The HS1JLW has a maximum reverse recovery time (trr) of 75 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed in the official Taiwan Semiconductor datasheet Version C2103 and reflects its suitability for switching frequencies up to 500 kHz. The HS1JLW's trr is identical to that of HS1KLW and HS1MLW, distinguishing it from faster variants like HS1GLW (50 ns).
How does the junction capacitance of the HS1JLW affect circuit performance?
The HS1JLW exhibits 16 pF typical junction capacitance (CJ) at 1 MHz and 4.0 V reverse bias-critical for minimizing high-frequency noise coupling in gate-drive bootstrap networks and reducing snubber losses in resonant converters. This value is significantly higher than HS1KLW/HS1MLW (7 pF), making the HS1JLW better suited for moderate-frequency applications where controlled ringing is preferred over ultra-low capacitance.
Is the HS1JLW RoHS-compliant and halogen-free?
Yes, the HS1JLW is RoHS-compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the Taiwan Semiconductor datasheet. Its molding compound meets UL 94V-0 flammability rating, and all materials are subject to TSC's substance compliance program. Traceability documentation and CoC are available upon request for HS1JLW orders placed through Aetrix Electronics.
