Product details
Overview
HSJLWH from Taiwan Semiconductor is a 600 V repetitive peak reverse voltage, 0.8 A average forward current, surface-mount silicon rectifier in SOD-123W package, featuring 1.31 V typical forward voltage at 0.8 A and 25°C, 75 ns maximum reverse recovery time, and AEC-Q101 qualification for automotive use in snubber and freewheeling circuits.
For engineers reviewing the HSJLWH datasheet, HSJLWH pinout, HSJLWH application, or HSJLWH equivalent, key selection criteria include its 600 V VRRM, 20 A IFSM, 150°C maximum junction temperature, glass-passivated junction, and SOD-123W low-profile package with cathode band polarity marking.
Technical Context
The HSJLWH is a single-die, standard recovery silicon rectifier optimized for medium-voltage switching applications where fast but not ultrafast recovery is required. Its 75 ns trr and 5 pF junction capacitance at 1 MHz / 4 V support efficient operation in DC–DC converters and automotive lighting drivers up to ~100 kHz switching frequencies.
Thermally, it delivers RθJL = 34°C/W and RθJA = 86°C/W when mounted on a 5 mm × 5 mm copper pad, enabling reliable 0.8 A continuous conduction at ambient temperatures up to 105°C without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports input rails up to 424 V DC or 600 V peak AC in offline or boost converter stages |
| IF | 0.8 A - rated continuous forward current at TA = 75°C on standard PCB layout |
| IFSM | 20 A - withstands short-duration inrush or surge currents (8.3 ms half-sine) |
| VF @ 0.8A, 25°C | 1.31 V typ / 1.70 V max - determines conduction loss and thermal rise in freewheeling paths |
| trr | 75 ns max - limits switching losses and EMI in <100 kHz hard-switched topologies |
| CJ @ 1 MHz, 4 V | 5 pF - minimizes capacitive coupling and high-frequency displacement current |
| TJ max | 150°C - enables operation in under-hood automotive environments with margin |
Pinout & Package
Package: SOD-123W - low-profile, surface-mount plastic package with matte tin-plated leads, moisture sensitivity level 1 (J-STD-020), UL 94V-0 molding compound, and cathode band polarity indicator.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Cathode | Forward current exit terminal | Marked by visible band; connects to output rail or ground return path |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per stress test requirements |
| Glass passivated junction | Enhances long-term stability and humidity resistance vs. epoxy-passivated alternatives |
| SOD-123W low-profile footprint | Enables automated placement and fits tight board spaces; 1.3 mm max height |
| Junction-to-lead thermal resistance | RθJL = 34°C/W - allows direct heat transfer to PCB copper, simplifying thermal design |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for eco-conscious manufacturing |
Applications
| DC–DC Converter | Automotive Lighting |
|---|---|
Use Scenario: Secondary-side rectification in isolated flyback or forward converters powering infotainment systems. IC Role / Device Role / Timing Role: Freewheeling diode conducting during MOSFET off-time to maintain output current continuity. Use Value: 600 V VRRM and 75 ns trr reduce voltage overshoot and switching loss compared to slower 1N400x series. | Use Scenario: LED driver output stage in headlamp or DRL modules requiring robust reverse blocking. IC Role / Device Role / Timing Role: Reverse polarity protection and load dump clamping diode. Use Value: AEC-Q101 qualification and 150°C TJ max ensure reliability under engine bay thermal transients. |
| Snubber Network | Freewheeling Application |
Use Scenario: RC snubber across relay coils or inductive loads in body control modules. IC Role / Device Role / Timing Role: Clamp inductive kickback voltage spikes during turn-off. Use Value: 20 A IFSM handles transient energy without degradation; 5 pF CJ minimizes snubber loading at high frequency. | Use Scenario: Inductor current recirculation path in brushed DC motor drivers or solenoid controls. IC Role / Device Role / Timing Role: Provides low-loss current path when main switch opens. Use Value: 1.31 V VF at 0.8 A reduces power dissipation versus higher-VF alternatives like HSMLWH (1000 V version). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HSKLWH | 800 V VRRM, same IF/trr/package; 1.31 V VF @ 0.8A, 25°C identical | Required where system peak reverse voltage exceeds 600 V (e.g., 400 V bus with 20% tolerance) | Select HSJLWH for cost-optimized 600 V designs; HSJLWH has lower leakage than HSMLWH at same VR |
| HSGLWH | 400 V VRRM, lower VF (0.91 V typ @ 0.8A, 25°C), same trr/package | Suitable for 24–48 V DC systems (e.g., body electronics) where lower conduction loss is prioritized | HSJLWH provides higher voltage margin than HSGLWH but trades 0.4 V higher VF at full load |
Compared with HSJLWH, HSGLWH offers lower forward loss in low-voltage systems but insufficient reverse rating for 300+ V applications, while HSKLWH extends voltage capability at identical thermal and recovery performance-making HSJLWH the optimal balance for 600 V-rated automotive and industrial DC–DC stages.

FAQ
What is the peak repetitive reverse voltage rating of the HSJLWH?
The HSJLWH has a peak repetitive reverse voltage (VRRM) rating of 600 V. This value is confirmed in the Absolute Maximum Ratings table for the HSJLWH variant and defines the maximum reverse-biased voltage the device can block repeatedly without breakdown. It is distinct from the 200 V (HSDLWH) and 1000 V (HSMLWH) variants in the same family.
Is the HSJLWH qualified for automotive applications?
Yes, the HSJLWH is AEC-Q101 qualified. This qualification is explicitly stated in the FEATURES section of the official datasheet and verified across all electrical, thermal, and reliability test conditions defined in the AEC-Q101 standard, making HSJLWH suitable for under-hood and cabin automotive systems.
What is the forward voltage drop of the HSJLWH at 0.8 A and 25°C?
The HSJLWH exhibits a typical forward voltage (VF) of 1.31 V and a maximum of 1.70 V at 0.8 A and 25°C, as specified in the Electrical Specifications table. These values are measured under pulsed conditions (PW = 0.3 ms) and directly impact conduction loss and thermal design in HSJLWH-based circuits.
Which package does the HSJLWH use, and what are its key mechanical attributes?
The HSJLWH uses the SOD-123W package: a low-profile surface-mount outline with matte tin-plated leads, UL 94V-0 flammability rating, polarity indicated by cathode band, and moisture sensitivity level 1 per J-STD-020. Its weight is approximately 0.016 g, and it supports automated placement per the datasheet's mechanical data.
What is the maximum junction temperature and thermal resistance of the HSJLWH?
The HSJLWH has a maximum junction temperature (TJ) of 150°C and junction-to-lead thermal resistance (RθJL) of 34°C/W when mounted on a 5 mm × 5 mm copper pad, per the Thermal Performance section. These values define safe operating area boundaries and enable accurate thermal modeling of HSJLWH in real-world PCB layouts.
