Product details
Overview
HS1DLWH from Taiwan Semiconductor is a 1 A, 200 V repetitive peak reverse voltage surface-mount silicon rectifier diode in SOD-123W package, featuring glass passivated junction, 1.0 V max forward voltage at 1 A and 25°C, 30 A non-repetitive surge capability, and AEC-Q101 qualification for automotive use.
For engineers reviewing the HS1DLWH datasheet, HS1DLWH pinout, HS1DLWH application, or HS1DLWH equivalent, key selection criteria include its 200 V VRRM, low-profile SOD-123W footprint, 1.0 V forward drop, 50 ns reverse recovery time, and suitability for DC-DC converters and automotive lighting freewheeling circuits.
Technical Context
The HS1DLWH is a single-die, standard recovery silicon rectifier optimized for high-efficiency, low-loss operation in space-constrained surface-mount designs. Its glass passivated junction ensures robust reliability under thermal cycling and humidity exposure, while the SOD-123W package supports automated placement and meets JESD201 Class 2 whisker resistance.
With a maximum junction temperature of 175°C and RθJL = 25°C/W, the HS1DLWH delivers stable performance in thermally demanding environments such as under-hood automotive modules. Its 50 ns reverse recovery time and 16 pF junction capacitance at 1 MHz/4 V support moderate-speed switching in snubber and freewheeling roles without excessive ringing.

|---|---|
Use Scenario: Secondary-side rectification in isolated flyback or buck-derived LED driver supplying 12–48 V to automotive headlights or DRLs. IC Role / Device Role / Timing Role: Power rectifier conducting continuous forward current during switch off-time; blocks reverse voltage during switch on-time. Use Value: 1.0 V VF minimizes conduction loss at 1 A load, improving system efficiency; 175°C TJ(max) sustains operation near hot LED heatsinks. | Use Scenario: Freewheeling path for inductive current decay in PWM-controlled LED current regulators. IC Role / Device Role / Timing Role: Provides low-loss current recirculation path when MOSFET gate driver turns off, preventing voltage spikes across the switch. Use Value: 50 ns trr limits reverse recovery energy loss; 30 A IFSM safely absorbs transient energy from 100+ mH ballast inductors. |

IC Role / Device Role / Timing Role: Blocks reverse battery connection and conducts surge currents during load dump events. Use Value: AEC-Q101 qualification ensures survivability across -40°C to +125°C ambient; 1 µA IR at 25°C prevents standby current drain. |
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 MUR120SFT1G | 200 V VRRM, 1 A IF, 50 ns trr, but TO-277A package (larger footprint, higher RθJA) | Less suitable for ultra-thin automotive modules due to 1.7 mm height and thermal limitations | Select if board-level thermal management allows larger package and higher RθJA is acceptable |
| Vishay VS-1EWH02-M3/5AT | 200 V VRRM, 1 A IF, 35 ns trr, SOD-123W package, but not AEC-Q101 qualified | Not approved for automotive safety-critical systems requiring AEC-Q101 validation | Select only for industrial or consumer DC-DC where qualification is not mandated |
Compared with MUR120SFT1G and VS-1EWH02-M3/5AT, the HS1DLWH uniquely combines AEC-Q101 qualification, SOD-123W form factor, and 200 V/1 A/50 ns performance-making it the preferred choice for space- and reliability-constrained automotive power conversion.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the HS1DLWH?
The HS1DLWH has a maximum repetitive peak reverse voltage (VRRM) of 200 V. This rating defines the highest reverse voltage the device can block continuously without breakdown under normal operating conditions. It is verified per JEDEC test methods and applies across the full operating temperature range of –55°C to +175°C. The HS1DLWH datasheet confirms this value in the Absolute Maximum Ratings table on page 1.
Is the HS1DLWH qualified for automotive applications?
Yes, the HS1DLWH is AEC-Q101 qualified. This qualification includes stress tests for temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD), confirming its suitability for automotive power electronics. The qualification status is explicitly stated in the Features section of the official Taiwan Semiconductor datasheet (Version A2103), and the device carries full automotive-grade traceability and lot control.
What package type does the HS1DLWH use, and what are its key mechanical attributes?
The HS1DLWH uses the SOD-123W surface-mount package. Key mechanical attributes include a low profile (≤1.1 mm height), matte tin-plated leads compliant with J-STD-002 solderability, UL 94V-0 flammability rating, polarity indicated by cathode band, and a weight of approximately 0.016 g. These features support automated placement, high-density PCB layouts, and reliability in automotive thermal environments.
What is the forward voltage (VF) specification for the HS1DLWH at rated current?
The HS1DLWH has a maximum forward voltage (VF) of 1.0 V at 1 A forward current and 25°C junction temperature. This value is measured under pulsed conditions (PW = 0.3 ms) and represents the upper limit for conduction loss in power path design. The typical VF is lower, but design margins must be based on the 1.0 V maximum specified in the Electrical Specifications table.
Does the HS1DLWH have a specified reverse recovery time (trr)?
Yes, the HS1DLWH 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 parameter is confirmed in the Electrical Specifications table of the Taiwan Semiconductor datasheet (Version A2103) and reflects its suitability for moderate-speed switching applications such as DC–DC converter secondary-side rectification and freewheeling circuits.
