Product details
Overview
HSDLWH from Taiwan Semiconductor is a 200V repetitive peak reverse voltage, 0.8A average forward current, glass passivated surface-mount Schottky rectifier in SOD-123W package, qualified to AEC-Q101 and used in automotive DC-DC converters and freewheeling circuits.
For engineers reviewing the HSDLWH datasheet, HSDLWH pinout, HSDLWH application, or HSDLWH equivalent, key selection criteria include its 200V VRRM, 0.86V max forward voltage at 0.8A/25°C, 50ns reverse recovery time, AEC-Q101 qualification, and SOD-123W low-profile packaging for space-constrained automotive modules.
Technical Context
HSDLWH is a single-die, unidirectional silicon planar junction rectifier with glass passivation for enhanced reliability under thermal cycling and humidity stress. Its 200V VRRM and 20A IFSM support transient surge handling in snubber and flyback clamp networks.
The device operates across –55°C to +150°C junction temperature range and exhibits 0.97V max VF at 0.4A/25°C, 17pF junction capacitance at 1MHz/4V, and 34°C/W junction-to-lead thermal resistance on standard PCB mounting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse blocking voltage before breakdown; defines safe operating limit in DC-DC output rectification |
| IF | 0.8 A - Continuous average forward current rating at TA = 75°C; determines steady-state power delivery capability |
| IFSM | 20 A - Non-repetitive peak surge current (8.3ms half-sine); enables robustness against inductive kickback in freewheeling paths |
| VF (max) | 1.00 V @ 0.8A/25°C - Upper bound of forward conduction loss; directly impacts efficiency and thermal rise in high-duty-cycle operation |
| trr | 50 ns - Reverse recovery time under specified test conditions; critical for minimizing switching losses in 100–500 kHz DC-DC topologies |
| RθJL | 34 °C/W - Junction-to-lead thermal resistance on 5mm × 5mm Cu pad; enables accurate thermal modeling for board-level reliability |
| Junction temp | –55°C to +150°C - Full operational range; supports under-hood automotive environments without derating |
Pinout & Package
Package: SOD-123W - Low-profile, surface-mount plastic case with matte tin-plated leads, moisture sensitivity level 1 (J-STD-020), UL 94V-0 rated molding compound, and cathode band polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of load or switch node; requires thermal relief pad for solder joint reliability |
| Cathode | Forward current exit / reverse blocking terminal | Marked by visible band; ties to higher-potential rail or ground return; critical for correct orientation in automated placement |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD47 |
| Glass passivated junction | Prevents moisture ingress and metallization corrosion, extending lifetime in humid under-hood environments |
| SOD-123W low-profile package | 1.3mm max height enables use in ultra-thin modules such as LED headlamp drivers and ADAS sensor power supplies |
| Junction capacitance (17 pF) | Minimizes displacement current during fast voltage transitions, reducing EMI in high-frequency switching nodes |
| Moisture sensitivity level 1 | Eliminates bake requirement prior to reflow, supporting direct placement in high-volume SMT lines without process interruption |
Applications
| Automotive DC-DC Converter | Car Lighting Power Supply |
|---|---|
Use Scenario: Step-down conversion from 12V battery to 5V/3.3V rails for infotainment and body control units. IC Role / Device Role / Timing Role: Output rectifier in synchronous or asynchronous buck converter secondary side. Use Value: 200V VRRM provides margin against load dump transients; 50ns trr reduces switching loss at 300 kHz operation. | Use Scenario: Constant-current driver for LED headlamps and DRLs requiring stable, compact power stages. IC Role / Device Role / Timing Role: Freewheeling diode in boost or SEPIC LED driver topology. Use Value: 0.8A IF rating matches typical LED string currents; SOD-123W footprint minimizes board area in tight lamp housings. |
| Snubber Network | Freewheeling Application |
Use Scenario: RC snubber across MOSFET drain-source in flyback or forward converters to suppress voltage spikes. IC Role / Device Role / Timing Role: Fast-recovery clamping diode that conducts only during transient events. Use Value: 50ns trr ensures rapid turn-off after spike absorption, preventing false triggering of overvoltage protection. | Use Scenario: Inductive load commutation in solenoid drivers, fuel pump controllers, and HVAC actuators.

Use Value: 20A IFSM withstands repeated inductive surges; AEC-Q101 qualification guarantees longevity in 15-year vehicle life cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS0820Z | Same SOD-123W package, 20V VRRM, 0.8A IF, but Schottky architecture yields lower VF (~0.45V) and no reverse recovery | Not suitable for 200V blocking; limited to low-voltage DC-DC outputs or OR-ing | Select only when VRRM ≤ 20V and ultra-low forward loss is prioritized over voltage rating |
| MBR0520L | 0.5A IF, 20V VRRM, SOD-123 package (not SOD-123W), 0.45V VF, no trr specification due to Schottky construction | Lower current and voltage ratings; smaller thermal pad area limits power dissipation | Acceptable only for <0.5A, <20V auxiliary rails where footprint compatibility suffices and surge immunity is non-critical |
Compared with STPS0820Z and MBR0520L, HSDLWH uniquely delivers 200V blocking with AEC-Q101 qualification and 0.8A current in SOD-123W - making it the only viable option for automotive 12V-system freewheeling and snubbing where both voltage margin and reliability are mandatory.

FAQ
What is the maximum repetitive peak reverse voltage rating for HSDLWH?
HSDLWH has a VRRM rating of 200 V, verified per absolute maximum ratings table in the official TSC datasheet (Version A2103). This value defines the highest reverse voltage the device can block repeatedly without breakdown. It is not interchangeable with higher-voltage variants like HSMLWH (1000V); using HSDLWH beyond 200V risks catastrophic failure. The 200V rating makes HSDLWH appropriate for 12V automotive systems with load dump margins up to ISO 7637-2 Pulse 5a.
Is HSDLWH suitable for automotive applications and what qualification does it hold?
Yes, HSDLWH is explicitly qualified to AEC-Q101 for automotive use, confirmed in the FEATURES section of the TSC datasheet. This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and unbiased highly accelerated stress testing. HSDLWH is deployed in production automotive modules including DC-DC converters and LED lighting drivers, and its SOD-123W package meets JESD201 Class 2 whisker resistance requirements.
What is the forward voltage drop of HSDLWH at 0.8A and 25°C?
HSDLWH exhibits a maximum forward voltage (VF) of 1.00 V at IF = 0.8 A and TJ = 25°C, as specified in the ELECTRICAL SPECIFICATIONS table. The typical value is 0.86 V under the same conditions. This VF directly determines conduction loss (Pcond = IF × VF) and must be used in thermal calculations alongside RθJL = 34°C/W to ensure junction temperature remains below 150°C in final layout.
Does HSDLWH have a defined reverse recovery time and why does it matter?
Yes, HSDLWH has a specified reverse recovery time (trr) of 50 ns maximum under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A test conditions. This parameter is critical in switching power supplies because slower recovery increases switching losses and EMI generation. At 50 ns, HSDLWH supports efficient operation in 300–500 kHz DC-DC converters commonly used in modern automotive ECUs and lighting systems.
What is the package type and thermal performance of HSDLWH?
HSDLWH uses the SOD-123W package - a low-profile surface-mount outline with 1.3 mm max height, matte tin-plated leads, and UL 94V-0 molding compound. Its thermal performance includes RθJL = 34°C/W and RθJA = 86°C/W when mounted on a 5 mm × 5 mm copper pad per JEDEC standards. These values enable accurate thermal simulation and confirm suitability for thermally constrained automotive modules without forced airflow.
