Product details
Overview
HS15MLW from Taiwan Semiconductor is a 1.5A, 1000V repetitive peak reverse voltage surface-mount silicon rectifier diode in SOD-123W package, featuring 1.30V max forward voltage at 1.5A/25°C, 75ns reverse recovery time, and 9pF junction capacitance - deployed in high-efficiency DC-DC converters and switching inverters.
For engineers reviewing the HS15MLW datasheet, HS15MLW pinout, HS15MLW application, or HS15MLW equivalent, key selection criteria include its 1000V VRRM, low-profile SOD-123W thermal performance (RθJL = 43°C/W), and verified 150°C junction temperature rating for industrial power conversion designs.
Technical Context
The HS15MLW is a single-die, glass-passivated silicon PN junction rectifier optimized for high-voltage switching applications. Its 1000V VRRM and 40A IFSM support robust surge handling in flyback and freewheeling topologies, while its 75ns trr enables operation up to several hundred kHz.
Thermal design is enabled by RθJA = 84°C/W on a 5mm × 5mm Cu pad PCB, and RθJL = 43°C/W confirms efficient heat transfer to the PCB lead. Reverse leakage remains ≤150µA at 125°C, ensuring stable blocking under elevated ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - maximum repetitive reverse voltage before breakdown; defines safe operating range in high-voltage DC bus or PFC stages |
| IF | 1.5 A - continuous forward current rating; supports sustained conduction in 12–48V output DC-DC converters |
| VF (max) | 1.70 V @ 1.5A, 25°C - directly impacts conduction loss and thermal rise in high-duty-cycle rectification |
| trr | 75 ns - limits switching loss and EMI in high-frequency SMPS; lower than 200–600V variants in same family |
| CJ | 9 pF @ 4V - reduces capacitive coupling and improves noise immunity in fast-switching gate-drive or snubber circuits |
| RθJL | 43 °C/W - enables direct thermal path to PCB copper; critical for compact, unheatsinked power supply layouts |
| TJ(max) | 150 °C - allows operation in sealed enclosures or high-ambient industrial environments without derating |
Pinout & Package
Package: SOD-123W - low-profile, surface-mount plastic case with matte tin-plated leads, UL 94V-0 rated molding compound, and cathode band polarity marking. Weight: 0.016g.
| Pin/Terminal | Circuit Role | Design Meaning |

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, 1.1A IF, 50ns trr, SOD-123 package | Lower voltage rating and current; unsuitable for 1000V bus designs | Select only when system VRRM requirement ≤600V and layout allows tighter thermal margin |
| SB1100 | 100V VRRM, 1A IF, Schottky architecture, 0.85V VF | Not a high-voltage solution; lacks blocking capability for >200V applications | Use only in low-voltage, high-efficiency outputs where 1000V blocking is unnecessary |
Compared with STTH1L06S and SB1100, the HS15MLW uniquely delivers 1000V blocking at 1.5A with validated 75ns recovery - making it the sole option among the three for 800–1000V industrial DC bus rectification without series stacking.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for HS15MLW?
The HS15MLW has a VRRM rating of 1000V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version C2103). This value is specific to the HS15MLW variant and distinguishes it from lower-voltage members like HS15DLW (200V) and HS15KLW (800V). The 1000V rating ensures reliable blocking in high-voltage industrial and telecom power applications.
Does HS15MLW have a specified reverse recovery time (trr)?
Yes, the HS15MLW has a maximum reverse recovery time of 75ns under test conditions of IF = 0.5A, IR = 1.0A, and Irr = 0.25A. This value is explicitly listed in the Electrical Specifications table for HS15JLW through HS15MLW variants. It reflects the device's suitability for high-frequency switching topologies up to several hundred kHz.
What is the forward voltage (VF) of HS15MLW at full rated current?
The HS15MLW exhibits a maximum forward voltage of 1.70V at IF = 1.5A and TJ = 25°C, as specified in the Electrical Specifications table. At elevated junction temperature (125°C), VF drops to 1.30V max under the same current, due to the negative temperature coefficient of silicon PN junctions - a behavior confirmed across all HS15xLW variants.
Is HS15MLW compliant with RoHS and halogen-free standards?
Yes, HS15MLW is RoHS compliant and halogen-free per IEC 61249-2-21, as stated in the FEATURES section of the official datasheet. The device uses matte tin-plated leads and UL 94V-0 molding compound, meeting both environmental and flammability requirements for industrial and consumer end equipment.
What is the thermal resistance from junction to lead (RθJL) for HS15MLW?
The HS15MLW has a typical junction-to-lead thermal resistance (RθJL) of 43°C/W, measured with the device mounted on a standard 5mm × 5mm copper pad PCB. This value is identical across the HS15DLW–HS15MLW family and is critical for estimating temperature rise when designing thermally constrained power supply layouts.
