Product details
Overview
HS15MLWH from Taiwan Semiconductor is a 1.5A, 1000V repetitive peak reverse voltage (VRRM) surface-mount silicon rectifier in SOD-123W package, featuring 1.30V max forward voltage at 1.5A/25°C, 75ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability in freewheeling and snubber circuits.
For engineers reviewing the HS15MLWH datasheet, HS15MLWH pinout, HS15MLWH application, or HS15MLWH equivalent, key selection considerations include its 1000V VRRM, 40A IFSM, glass-passivated junction, JESD201 Class 2 whisker resistance, and moisture sensitivity level 1 compliance - all critical for high-reliability DC-DC and automotive lighting designs.
Technical Context
The HS15MLWH is a single-die, low-profile SOD-123W packaged fast recovery rectifier optimized for high-voltage switching applications. Its 1000V VRRM and 75ns trr enable efficient operation in flyback snubbers and freewheeling paths where voltage clamping and rapid turn-off are required.
Thermal performance is defined by RθJL = 43°C/W and RθJA = 84°C/W on a 5mm × 5mm Cu pad PCB, supporting continuous 1.5A conduction up to TJ = 150°C. The device uses matte tin-plated leads and meets UL 94V-0 flammability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in high-voltage clamp or snubber circuits |
| IF | 1.5 A - Continuous average forward current rating; determines thermal design margin on PCB copper area |
| trr | 75 ns - Reverse recovery time; enables use in 100–500 kHz switching topologies with minimal switching loss |
| VF @ 1.5A/25°C | 1.30 V max - Forward voltage drop; directly impacts conduction loss and thermal rise in high-duty-cycle operation |
| IFSM | 40 A - Non-repetitive peak surge current; supports robustness against inrush or transient overcurrent events |
| TJ max | 150 °C - Maximum junction temperature; sets upper boundary for thermal management in enclosed automotive environments |
Pinout & Package
Package: SOD-123W - Low-profile, surface-mount plastic case with cathode band polarity marking; 0.016g weight; UL 94V-0 rated molding compound; matte tin-plated leads compliant with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of load or switch node; requires adequate copper pour for thermal dissipation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06S | 600V VRRM, 1.0A IF, TO-277 package, 50ns trr | Limited to ≤600V systems; higher current density but lower voltage margin than HS15MLWH | Prefer when space-constrained layouts require TO-277 and system VR stays below 420V RMS |
| ON Semi MUR160 | 600V VRRM, 1.0A IF, DO-41 through-hole, 75ns trr | Through-hole mounting; lacks AEC-Q101 qualification and moisture level 1 rating | Select only for non-automotive, cost-sensitive prototyping where SMT assembly is unavailable |
Compared with STTH1L06S and MUR160, the HS15MLWH delivers 1000V blocking capability and AEC-Q101 qualification in an SMT-compatible SOD-123W package - making it uniquely suitable for production automotive snubbers and EV auxiliary supplies where voltage margin and reliability are non-negotiable.
