Product details
Overview
HSGLWH from Taiwan Semiconductor is a 400 V, 0.8 A glass-passivated surface-mount rectifier in SOD-123W package, rated for 20 A surge current and 150 °C max junction temperature, with typical forward voltage of 0.91 V at 0.8 A and 25 °C - used in automotive lighting and DC-DC converter freewheeling paths.
For engineers reviewing the HSGLWH datasheet, HSGLWH pinout, HSGLWH application, or HSGLWH equivalent, key selection criteria include its AEC-Q101 qualification, low-profile SOD-123W footprint, 34 °C/W junction-to-lead thermal resistance, and verified reverse recovery time ≤50 ns under 0.5 A forward / 1.0 A reverse test conditions.
Technical Context
This device is a single-die, unidirectional silicon planar junction rectifier optimized for high-efficiency switching power supplies and automotive systems requiring robust thermal performance and reliability. Its glass-passivated chip junction ensures stable operation across -55 °C to +150 °C ambient range and meets JESD201 Class 2 whisker resistance.
The SOD-123W package enables automated placement and provides UL 94V-0 flammability rating with matte tin-plated leads. Polarity is marked by cathode band, and moisture sensitivity level is rated J-STD-020 Level 1 - eliminating bake requirements prior to reflow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum repetitive peak reverse voltage; defines safe blocking capability in snubber or freewheeling circuits |
| IF | 0.8 A continuous - average forward current rating at TA = 25 °C; derates linearly above 25 °C per curve Fig.1 |
| IFSM | 20 A - non-repetitive peak surge current (8.3 ms half-sine); supports inrush and transient load handling |
| VF @ 0.8A, 25°C | 0.91 V typ / 1.30 V max - forward voltage drop directly impacts conduction loss and thermal design in DC-DC stages |
| trr | ≤50 ns - reverse recovery time measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; critical for high-frequency switching efficiency |
| RθJL | 34 °C/W - junction-to-lead thermal resistance on 5 mm × 5 mm Cu pad; enables accurate thermal modeling without heatsink |
| IR @ 400V, 125°C | ≤150 µA - maximum leakage at full rated voltage and high temperature; ensures low standby power loss |
Pinout & Package
SOD-123W is a low-profile, surface-mount plastic package with two terminals: anode and cathode. Cathode polarity is indicated by a visible band on the device body. The package measures 2.7 mm × 1.6 mm × 1.0 mm (L × W × H) and weighs approximately 0.016 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to input/high-side node in freewheeling or snubber configurations; must withstand full surge current |
| Cathode | Forward current exit point | Marked by band; ties to return/low-side node; determines directionality in DC-DC output rectification |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, mechanical shock, and humidity testing |
| Glass-passivated junction | Provides stable electrical characteristics and long-term stability under high-humidity and high-temperature operating conditions |
| Junction-to-lead RθJL = 34 °C/W | Enables direct PCB copper pad thermal path - no external heatsink needed for 0.8 A continuous operation at 70 °C ambient |
| Moisture sensitivity Level 1 | Zero bake requirement before reflow; compatible with standard SMT assembly lines without dry-pack handling |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU - suitable for environmentally regulated automotive and industrial programs |
Applications
| Automotive Lighting | DC-DC Converter Freewheeling |
|---|---|
Use Scenario: LED headlamp and DRL driver modules requiring compact, thermally efficient rectification. IC Role / Device Role / Timing Role: Freewheeling diode in buck or boost converters driving constant-current LED strings. Use Value: Low VF (0.91 V typ) minimizes conduction loss and thermal rise in space-constrained lamp housings. | Use Scenario: Secondary-side rectification in isolated flyback or forward converters for infotainment power rails. IC Role / Device Role / Timing Role: Unidirectional current path during switch-off phase; handles 20 A surge during transient load steps. Use Value: trr ≤50 ns reduces switching losses and EMI generation at 200–500 kHz switching frequencies. |
| Snubber Network | Automotive Body Control Module (BCM) |
Use Scenario: RC snubber across MOSFET or relay contacts in HVAC blower or seat motor drivers. IC Role / Device Role / Timing Role: Clamp inductive kickback energy and suppress voltage spikes during turn-off. Use Value: 400 V VRRM and 150 °C TJ rating ensure reliable clamping under repeated high-dV/dt transients. | Use Scenario: Power supply input rectification and reverse-polarity protection in door module or mirror control units.

Use Value: AEC-Q101 qualification and J-STD-020 Level 1 moisture rating support zero-defect manufacturing and field longevity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH0.8L04S | Same 400 V VRRM, 0.8 A IF, but TO-277 package (larger footprint, higher RθJA) | Less suitable for ultra-compact automotive PCBs due to 4.5 mm × 3.5 mm outline vs. SOD-123W's 2.7 mm × 1.6 mm | Prefer HSGLWH where board area and thermal coupling to copper are constrained |
| SB0840 | 40 V lower VRRM (360 V), same SOD-123W package, VF ≈ 0.89 V at 0.8 A | Not recommended for 400 V bus designs; acceptable only in marginally rated 350 V systems | Select HSGLWH when full 400 V blocking margin is required per ISO 7637-2 pulse 5a |
Compared with STTH0.8L04S and SB0840, HSGLWH delivers superior board-area efficiency and automotive-grade qualification in the smallest possible footprint, while maintaining tighter VF consistency across temperature and meeting stricter reverse leakage limits at 125 °C.

FAQ
What is the maximum junction temperature rating for HSGLWH?
The HSGLWH has a maximum junction temperature (TJ MAX) of +150 °C, validated per absolute maximum ratings table. This allows operation in under-hood automotive environments where ambient temperatures reach 125 °C, provided thermal design maintains junction temperature below this limit using the specified RθJL = 34 °C/W path to PCB copper.
Is HSGLWH pin-compatible with other devices in the HSxLWH family?
Yes - all HSxLWH variants (HSDLWH, HSGLWH, HSJLWH, etc.) share identical SOD-123W package dimensions, pinout, and terminal configuration. Voltage rating differences (200–1000 V) do not affect mechanical or soldering compatibility, enabling single-footprint BOM flexibility across voltage grades.
Does HSGLWH require moisture preconditioning before reflow soldering?
No - HSGLWH is rated J-STD-020 Moisture Sensitivity Level 1, meaning it may be stored and processed in ambient conditions indefinitely without baking. This eliminates pre-reflow bake cycles and simplifies SMT line integration for high-volume automotive production.
What is the reverse recovery time (trr) specification for HSGLWH?
The HSGLWH has a maximum reverse recovery time (trr) of 50 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions. This value is confirmed in the Electrical Specifications table and supports efficient operation in switching power supplies up to 500 kHz without excessive switching loss or ringing.
How does the forward voltage of HSGLWH vary with temperature?
HSGLWH exhibits negative temperature coefficient for VF: at 0.8 A, VF drops from 0.91 V typ at 25 °C to 0.77 V typ at 125 °C. This behavior improves thermal stability in high-temperature operation but requires verification of minimum voltage headroom in low-VF-dependent feedback loops.
