Product details
Overview
HS15DLWH from Taiwan Semiconductor is a 1.5A, 200V surface-mount high-efficiency rectifier diode in SOD-123W package, featuring glass-passivated junction, AEC-Q101 qualification, and low forward voltage (0.82V typ. @ 0.75A, 25°C). It serves as a freewheeling or snubber diode in automotive DC-DC converters and car lighting systems.
For engineers reviewing the HS15DLWH datasheet, HS15DLWH pinout, HS15DLWH application, or HS15DLWH equivalent, key selection criteria include its 200V VRRM, 40A IFSM, 150°C TJMAX, J-STD-020 Level 1 moisture sensitivity, and verified performance under 125°C junction conditions.
Technical Context
This device is a single-die, unidirectional silicon rectifier optimized for high-reliability automotive power conversion. Its glass-passivated junction ensures stable reverse leakage (<1 µA @ 25°C, <150 µA @ 125°C) and robust surge tolerance (40A IFSM, 8.3ms half-sine).
The SOD-123W package delivers low thermal resistance (RθJL = 43°C/W), enabling efficient heat transfer to PCB copper pads. Reverse recovery time is specified at ≤50 ns under defined test conditions (IF = 0.5A, IR = 1.0A, Irr = 0.25A), supporting moderate-frequency switching applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage before breakdown; defines safe operating range in DC-DC output or snubber circuits |

Applications
| DC-DC Converter | Automotive Lighting |
|---|---|
Use Scenario: Output rectification in isolated flyback or non-isolated buck-boost converters powering infotainment or ADAS subsystems. IC Role / Device Role / Timing Role: Freewheeling diode conducting during MOSFET off-time; clamps inductive energy and transfers power to output capacitor. Use Value: Low VF (0.82 V typ.) reduces conduction loss, improving converter efficiency at 12–48 V input ranges typical in vehicle architectures. | Use Scenario: LED headlamp or daytime running light (DRL) driver with PWM dimming and reverse-polarity protection. IC Role / Device Role / Timing Role: Polarity protection diode and snubber element across relay coils or MOSFET switches controlling LED strings. Use Value: AEC-Q101 qualification and 150°C TJMAX ensure reliable operation in high-ambient under-hood or lamp housing environments. |
| Snubber Network | Freewheeling Application |
Use Scenario: RC snubber across primary-side MOSFETs or ignition coils in 12V/48V mild-hybrid systems. IC Role / Device Role / Timing Role: Clamps voltage spikes during turn-off using fast recovery (≤50 ns) and low CJ (25 pF) to minimize ringing. Use Value: Controlled trr and predictable CJ allow precise snubber tuning without excessive power dissipation or EMI generation. | Use Scenario: Inductive load suppression in seat motor, window lift, or HVAC blower circuits. IC Role / Device Role / Timing Role: Freewheeling path for back-EMF when driving brushed DC motors or solenoids via N-channel MOSFETs. Use Value: 40A IFSM handles high-energy inductive kickback; glass passivation prevents degradation under repeated surge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS1L20A | 1.2A IF, 200V VRRM, SMA package, 0.55V VF @ 1.2A - lower current, lower VF, larger footprint | Not AEC-Q101 qualified; suited for industrial/commercial DC-DC but not automotive front-end | Select if lower VF is critical and AEC-Q101 is not required; verify thermal margin with RθJA = 110°C/W |
| RB050M-30 | 1.0A IF, 30V VRRM, SOD-123 package, 0.45V VF @ 1A - much lower voltage rating, Schottky architecture | Designed for low-voltage logic supply rectification; unsuitable for 200V snubber or automotive 12V+ freewheeling | Only consider for sub-30V applications where ultra-low VF outweighs voltage and surge requirements |
Compared with STPS1L20A and RB050M-30, the HS15DLWH uniquely combines AEC-Q101 compliance, 200V VRRM, 1.5A IF, and SOD-123W packaging-making it the only option among the three qualified for automotive under-hood freewheeling and snubber use.

FAQ
What is the maximum junction temperature rating for HS15DLWH?
The HS15DLWH has a maximum junction temperature (TJMAX) of +150°C, validated per AEC-Q101 stress testing. This allows continuous operation in under-hood automotive environments when mounted on a 5 mm × 5 mm Cu pad (RθJA = 84°C/W). Derating curves in the datasheet define usable IF at elevated ambient temperatures, and thermal design must ensure actual TJ remains below 150°C under worst-case load and ambient conditions. The HS15DLWH achieves this with glass-passivated die and low RθJL (43°C/W).
Is HS15DLWH suitable for use in automotive applications?
Yes, the HS15DLWH is AEC-Q101 qualified and explicitly designed for automotive applications including DC-DC converters, car lighting, and snubber circuits. Its construction features glass-passivated junction, J-STD-020 Level 1 moisture sensitivity, halogen-free materials, and operation over –55°C to +150°C. The HS15DLWH meets automotive reliability standards for temperature cycling, high-temperature reverse bias, and mechanical robustness-making it appropriate for engine bay, cabin, and exterior lighting modules.
What is the forward voltage drop of HS15DLWH at rated current?
The HS15DLWH exhibits a typical forward voltage (VF) of 0.82 V at 0.75 A and 25°C, rising to 0.88 V at 1.5 A and 25°C. At elevated junction temperature (125°C), VF decreases to 0.68 V (0.75 A) and 0.75 V (1.5 A), reflecting silicon's negative temperature coefficient. These values are measured under pulsed conditions (PW = 0.3 ms) and directly impact conduction loss in power stages. The HS15DLWH's VF performance balances efficiency and ruggedness for 200V-class rectification.
Does HS15DLWH have a specified reverse recovery time?
Yes, the HS15DLWH has a maximum reverse recovery time (trr) of 50 ns, tested under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value supports use in moderate-frequency switching applications such as 50–100 kHz DC-DC converters and snubbers. The HS15DLWH's trr is confirmed in the Electrical Specifications table and validated across temperature; it is significantly faster than general-purpose rectifiers but slower than ultrafast or Schottky alternatives.
What package type does HS15DLWH use and what are its key mechanical attributes?
The HS15DLWH uses the SOD-123W surface-mount package: low-profile, UL 94V-0 rated, with matte tin-plated leads compliant with J-STD-002 solderability. Polarity is marked by a cathode band, and the device weighs approximately 0.016 g. Its mechanical outline matches JEDEC standard SOD-123W, and recommended pad layout is provided in the datasheet. The HS15DLWH's SOD-123W package enables automated placement and offers superior thermal performance (RθJL = 43°C/W) compared to standard SOD-123.
