Product details
Overview
HS1GLWH from Taiwan Semiconductor is a 1 A, 400 V repetitive peak reverse voltage (VRRM) surface-mount high-efficiency rectifier in SOD-123W package, featuring 1.3 V max forward voltage at 1 A and 50 ns reverse recovery time, widely used in automotive lighting and DC-DC converters.
For engineers reviewing the HS1GLWH datasheet, HS1GLWH pinout, HS1GLWH application, or HS1GLWH equivalent, key selection criteria include its AEC-Q101 qualification, glass-passivated junction, J-STD-020 Level 1 moisture sensitivity, UL 94V-0 molding compound, and compatibility with automated placement in space-constrained automotive and industrial power stages.
Technical Context
The HS1GLWH is a single-die, standard recovery silicon rectifier optimized for medium-voltage freewheeling and snubber applications where low conduction loss and robust thermal performance are required. Its 25 °C/W junction-to-lead thermal resistance supports reliable operation up to 175 °C junction temperature.
Unlike fast or ultrafast rectifiers, the HS1GLWH uses a standard recovery architecture with 50 ns trr - balancing switching efficiency and EMI control in non-resonant topologies. It is not designed for high-frequency synchronous rectification but excels in 50–200 kHz DC-DC stages and automotive LED driver flyback circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - supports input rails up to 280 V DC or 200 V RMS AC in bridge or half-wave configurations |
| IF | 1 A continuous - suitable for low-power auxiliary supplies and LED driver bias rails |
| IFSM | 30 A (8.3 ms) - withstands inrush and transient surge currents in automotive cold-crank conditions |
| VF max | 1.3 V @ 1 A, 25°C - enables <1.3 W conduction loss at full load, reducing thermal burden on PCB |
| trr | 50 ns - limits switching loss and voltage overshoot in moderate-speed flyback and buck-derived topologies |
| Junction temp | −55°C to +175°C - meets under-hood automotive ambient requirements without derating |
| CJ | 16 pF @ 1 MHz, 4 V - minimizes capacitive coupling noise in high-dv/dt snubber networks |
Pinout & Package
Package: SOD-123W - low-profile, surface-mount plastic case with matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance; polarity indicated by cathode band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to lower-potential node (e.g., switch node in flyback secondary or ground return in snubber) |
| Cathode | Current exit point during forward conduction; marked with band | Connected to higher-potential node (e.g., output rail or clamp voltage reference) |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and UHAST - enables use in engine control and lighting modules |
| Glass-passivated junction | Enhances long-term stability and humidity resistance versus epoxy-passivated alternatives, critical for under-hood longevity |
| Moisture sensitivity level 1 | No floor life limitation or bake requirement before reflow - simplifies SMT line logistics and reduces handling cost |
| UL 94V-0 molding compound | Self-extinguishing encapsulation meets automotive flame-retardancy mandates for PCB-mounted components |
| Low profile (SOD-123W) | Height ≤ 1.1 mm - fits beneath heat shields and in tight board-to-housing gaps typical in headlamp assemblies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L04S | Same 1 A / 400 V rating, but TO-277 package (higher RθJA = 100 °C/W); VF = 1.15 V typ | Requires larger PCB area and heatsinking; less suitable for ultra-thin automotive modules | Prefer HS1GLWH when SOD-123W footprint, AEC-Q101, or moisture level 1 are mandatory |
| ON Semi MUR140 | Higher VRRM (400 V), same SOD-123 package, but not AEC-Q101 qualified; VF = 1.25 V max | Lacks automotive qualification and J-STD-020 Level 1 compliance; limited to industrial/commercial use | Choose HS1GLWH for automotive production; MUR140 only for cost-sensitive non-automotive prototypes |
Compared with STTH1L04S and MUR140, the HS1GLWH uniquely combines AEC-Q101 qualification, SOD-123W low-profile packaging, J-STD-020 Level 1 handling, and 50 ns recovery in a single 1 A / 400 V rectifier - making it the only option qualified for volume production in automotive lighting and under-hood power conversion.

FAQ
What is the maximum junction temperature rating for the HS1GLWH?
The HS1GLWH has a maximum junction temperature (TJMAX) of +175°C, validated per AEC-Q101 stress testing. This rating allows operation in under-hood automotive environments and sealed industrial enclosures without derating up to 85°C ambient. The HS1GLWH maintains specified electrical parameters within this range, and its 25°C/W junction-to-lead thermal resistance supports effective heat transfer to the PCB copper pour.
Is the HS1GLWH pin-compatible with other SOD-123W rectifiers like the MUR120?
The HS1GLWH uses the standard SOD-123W package with anode and cathode terminals matching industry-standard SOD-123W pinout - enabling direct PCB footprint reuse. However, the HS1GLWH is not functionally identical to MUR120 due to differences in VF, trr, and qualification status; MUR120 lacks AEC-Q101 and has higher VF (1.5 V max). Always verify layout clearance and thermal pad design for HS1GLWH's specific thermal performance.
Does the HS1GLWH meet RoHS and halogen-free requirements?
Yes, the HS1GLWH is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound contains no brominated flame retardants, and lead content is below 1000 ppm. These compliance statements are verified in TSC's official product declaration and supported by material test reports available upon request for HS1GLWH production lots.
What is the reverse recovery time (trr) specification for the HS1GLWH?
The HS1GLWH has a maximum reverse recovery time (trr) of 50 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed in TSC's A2103 datasheet revision and applies across the full operating temperature range. The 50 ns trr balances low switching loss and manageable EMI in 50–200 kHz power stages where ultrafast diodes would increase noise without efficiency benefit.
Can the HS1GLWH be used in a freewheeling application with 12 V automotive battery input?
Yes, the HS1GLWH is rated for 400 V VRRM, making it fully suitable for 12 V automotive freewheeling applications - including relay coil suppression, solenoid drivers, and brushed DC motor commutation. Its AEC-Q101 qualification, −55°C to +175°C operating range, and glass-passivated junction ensure reliability during load dump transients and repeated thermal cycling. The HS1GLWH's 1.3 V VF also limits power dissipation to <1.3 W at 1 A continuous.
