Product details
Overview
HS1JLWH from Taiwan Semiconductor is a 1 A, 600 V high-efficiency surface-mount silicon rectifier diode in SOD-123W package, featuring 1.7 V max forward voltage at 1 A, 75 ns reverse recovery time, and 16 pF junction capacitance at 1 MHz / 4.0 V reverse bias - used in automotive DC-DC converters and freewheeling paths.
For engineers reviewing the HS1JLWH datasheet, HS1JLWH pinout, HS1JLWH application, or HS1JLWH equivalent, key selection criteria include peak reverse voltage (600 V), thermal resistance (25 °C/W junction-to-lead), AEC-Q101 qualification, moisture sensitivity level 1, and SOD-123W footprint compatibility with automated placement.
Technical Context
The HS1JLWH is a single-die, glass-passivated, planar junction silicon rectifier optimized for high-speed switching and low conduction loss. Its 75 ns reverse recovery time and 16 pF junction capacitance at 1 MHz/4.0 V support efficient operation in 100–500 kHz DC-DC topologies.
Rated for TJ = –55°C to +175°C and qualified to AEC-Q101, it delivers stable performance under automotive thermal cycling and vibration stress. The SOD-123W package provides 80 °C/W junction-to-ambient thermal resistance and supports 30 A non-repetitive surge current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - blocks up to 600 V repetitive reverse voltage without breakdown in snubber or flyback clamp circuits |
| IF | 1 A continuous - supports steady-state output rectification in compact 5–20 W automotive power supplies |
| VF (max) | 1.7 V @ 1 A, 25°C - limits conduction loss to ≤1.7 W per diode at full load, reducing thermal stress |
| trr | 75 ns - enables use in hard-switched converters up to ~500 kHz without excessive switching loss |
| CJ | 16 pF @ 1 MHz, VR = 4.0 V - minimizes capacitive coupling noise in high dv/dt gate-drive or sensing nodes |
| RθJL | 25 °C/W - allows direct PCB copper pour heat sinking to maintain <125°C junction temp at 1 A DC |
| AEC-Q101 | Qualified - certified for automotive under-hood applications including lighting and body control modules |
Pinout & Package
Package: SOD-123W - low-profile, surface-mount plastic case with matte tin-plated leads (J-STD-002 compliant), polarity indicated by cathode band, weight ≈ 0.016 g.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06S | 600 V VRRM, 1.05 A IF, 50 ns trr, TO-277A package (larger footprint) | Higher speed but requires PCB area increase; not AEC-Q101 qualified | Preferred where trr < 60 ns is critical and automotive qualification is not required |
| ES1J | 600 V VRRM, 1 A IF, 35 ns trr, DO-214AA package (higher profile) | Lower VF (~1.5 V) but larger height (2.3 mm vs. SOD-123W's 0.9 mm); no AEC-Q101 | Used when ultra-fast recovery dominates over board height and automotive compliance |
Compared with STTH1L06S and ES1J, the HS1JLWH uniquely combines AEC-Q101 qualification, SOD-123W low-profile packaging, and 600 V/1 A rating - making it the only drop-in rectifier for space-constrained, thermally demanding automotive modules requiring production-grade reliability.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the HS1JLWH?
The HS1JLWH has a VRRM of 600 V, meaning it can reliably block reverse voltages up to this level without breakdown. This rating is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version A2103) and applies across the full operating temperature range of –55°C to +175°C. Designers should maintain ≥20% voltage margin in clamping or flyback applications to ensure long-term reliability of the HS1JLWH.
Is the HS1JLWH qualified for automotive applications?
Yes, the HS1JLWH is AEC-Q101 qualified, as explicitly stated in the Features section of the Taiwan Semiconductor datasheet. This qualification covers stress tests including high-temperature operating life, temperature cycling, and mechanical shock - confirming suitability for under-hood and interior automotive systems. The HS1JLWH meets all requirements for use in production automotive ECUs, lighting modules, and power distribution units.
What is the junction capacitance (CJ) of the HS1JLWH and under what conditions is it specified?
The HS1JLWH has a typical junction capacitance of 16 pF, measured at 1 MHz with 4.0 V reverse bias (VR), as documented in the Electrical Specifications table. This value directly impacts high-frequency switching noise and EMI in DC-DC converters. It remains stable across temperature and is verified per JEDEC test methods - critical for predicting ringing behavior in buck or flyback snubber networks using the HS1JLWH.
What package type does the HS1JLWH use, and what are its key mechanical attributes?
The HS1JLWH uses the SOD-123W surface-mount package: low-profile (max height 0.9 mm), with matte tin-plated leads compliant with J-STD-002, moisture sensitivity level 1 (no bake required), and UL 94V-0 molding compound. Its marking code "HJLW" and cathode band provide unambiguous orientation for automated assembly - essential for high-yield placement in automotive PCB manufacturing lines using the HS1JLWH.
How does the thermal performance of the HS1JLWH compare to standard SOD-123 devices?
The HS1JLWH achieves RθJL = 25 °C/W and RθJA = 80 °C/W - significantly better than generic SOD-123 rectifiers (typically RθJA > 120 °C/W) due to optimized leadframe design and thermal interface in the SOD-123W variant. This allows the HS1JLWH to sustain 1 A DC current at ambient temperatures up to 100°C without external heatsinking, making it suitable for thermally dense automotive modules where airflow is limited.
