Product details
Overview
HS15DLW from Taiwan Semiconductor is a 1.5A, 200V surface-mount high-efficiency rectifier diode in SOD-123W package, featuring glass-passivated junction, 40A peak surge current rating, and low forward voltage (0.82V typ. at 0.75A/25°C). It serves as a freewheeling or output rectifier in DC-DC converters and switching-mode power supplies.
For engineers reviewing the HS15DLW datasheet, HS15DLW pinout, HS15DLW application, or HS15DLW equivalent, key selection factors include its 200V VRRM, 0.89V max forward voltage at 1.5A/25°C, 50ns reverse recovery time, thermal resistance of 43°C/W (junction-to-lead), and SOD-123W low-profile footprint compatibility with automated placement.
Technical Context
The HS15DLW is a single-die, silicon planar epitaxial rectifier optimized for high-frequency switching applications. Its glass-passivated junction ensures stable leakage performance up to 150°C junction temperature, and its 25pF junction capacitance at 4V supports efficient operation in 100kHz–1MHz SMPS topologies.
Designed for surface-mount assembly on standard PCBs with 5mm × 5mm copper pads, the device meets J-STD-020 moisture sensitivity level 1 and JESD201 Class 2 whisker resistance. Cathode polarity is marked by a visible band on the SOD-123W case.

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR110SFT1G | 1A, 1000V, TO-277 package; higher VF (1.25V max), slower trr (75ns), larger footprint | Higher voltage rating but lower current; unsuitable for 1.5A continuous use; requires layout change | Select only if >600V blocking is required and current demand is ≤1A |
| Vishay VS-1N5819TR-M3/54 | 1A, 40V, DO-214AC package; much lower VRRM, higher VF (0.975V), no glass passivation | Not rated for 200V systems; limited to low-voltage (<40V) applications like USB PD sink protection | Only acceptable for replacement in legacy 40V designs where voltage stress is confirmed <30V |
Compared with MUR110SFT1G and VS-1N5819TR-M3/54, the HS15DLW delivers optimal balance of 200V blocking, 1.5A current handling, and fast 50ns recovery in a compact SOD-123W package-making it uniquely suited for modern 12–24V SMPS where size, efficiency, and thermal performance are co-constrained.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for HS15DLW?
The HS15DLW has a maximum repetitive peak reverse voltage (VRRM) of 200 V, as specified in the Absolute Maximum Ratings table. This value is fixed for the HS15DLW variant and distinguishes it from other members of the HS15xLW family (e.g., HS15MLW = 1000 V). Exceeding 200 V in continuous reverse bias risks avalanche breakdown and permanent damage to the HS15DLW.
What is the typical forward voltage drop of HS15DLW at 1.5A and 25°C?
The typical forward voltage drop (VF) of the HS15DLW is 0.88 V at 1.5 A and 25°C, with a maximum of 0.95 V under the same conditions. This low VF is achieved via optimized silicon processing and contributes directly to reduced conduction losses in high-current DC-DC output stages where the HS15DLW is deployed.
Does HS15DLW have a defined reverse recovery time (trr)?
Yes, the HS15DLW has a specified reverse recovery time (trr) of up to 50 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and IRR = 0.25 A. This fast recovery characteristic is critical for minimizing switching losses and EMI in high-frequency (>100 kHz) power converters using the HS15DLW as a freewheeling or output rectifier.
What package type does HS15DLW use, and is it RoHS compliant?
The HS15DLW uses the SOD-123W surface-mount package and is fully RoHS compliant and halogen-free per IEC 61249-2-21. The device features matte tin-plated leads, meets J-STD-002 solderability requirements, and carries J-STD-020 moisture sensitivity level 1-eliminating pre-bake needs prior to reflow soldering of the HS15DLW.
Can HS15DLW replace older Schottky diodes like 1N5819 in existing designs?
The HS15DLW can replace 1N5819 in many 200V-class applications due to its higher VRRM (200V vs. 40V), superior thermal performance (RθJL = 43°C/W vs. ~60°C/W), and tighter VF spec (0.95V max vs. 0.975V max). However, layout verification is required: the SOD-123W footprint differs from DO-41/DO-204AL, so mechanical compatibility must be confirmed before substituting HS15DLW.
