Product details
Overview
HS15KLWH from Taiwan Semiconductor is a 1.5A, 800V glass-passivated surface-mount rectifier in SOD-123W package, rated for 40A surge current and 150°C junction temperature, with 1.31V max forward voltage at 1.5A/25°C and 75ns reverse recovery time - used in automotive lighting and DC-DC snubber circuits.
For engineers reviewing the HS15KLWH datasheet, HS15KLWH pinout, HS15KLWH application, or HS15KLWH equivalent, key selection criteria include VRRM = 800V, IF = 1.5A, trr = 75ns, thermal resistance RθJA = 84°C/W, and AEC-Q101 qualification for under-hood automotive use.
Technical Context
This high-efficiency fast recovery rectifier uses a single-die silicon construction with glass passivation for enhanced reliability and moisture resistance (J-STD-020 Level 1). Its low-profile SOD-123W package supports automated placement and meets UL 94V-0 flammability requirements.
The device delivers 800V repetitive peak reverse voltage with 1.31V typical forward voltage at 1.5A/25°C and 1.09V at 1.5A/125°C, enabling stable operation in high-temperature automotive environments while maintaining 75ns reverse recovery for reduced switching losses in snubber and freewheeling topologies.
Key Specifications

| VF @ 1.5A/25°C | 1.31 V max - Limits conduction loss to ≤1.97 W at full rated current, reducing thermal stress on PCB. |
| RθJA | 84 °C/W - Requires minimum 5 mm × 5 mm copper pad for safe operation at full current in ambient ≤85°C. |
| Junction Temp | −55°C to +150°C - Certified for under-hood automotive locations per AEC-Q101 stress testing. |
| CJ | 9 pF @ 1 MHz / 4 V - Low capacitance minimizes high-frequency coupling and EMI in fast-switching nodes. |

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for HS15KLWH?
The HS15KLWH has a VRRM of 800 V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version A2103). This rating defines the highest reverse voltage the device can block repeatedly without breakdown, and is critical for selecting appropriate safety margins in 400–600V DC bus applications. The HS15KLWH is part of a family spanning 200V to 1000V, with 'K' denoting the 800V grade.
Is HS15KLWH qualified for automotive applications?
Yes, the HS15KLWH is explicitly AEC-Q101 qualified per the manufacturer's documentation. It undergoes stress testing including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge per JESD22 standards. This qualification validates its suitability for under-hood automotive systems such as LED headlamps and body control units where reliability across −40°C to +125°C ambient is mandatory.
What is the forward voltage (VF) of HS15KLWH at 1.5A and 25°C?
The HS15KLWH exhibits a maximum forward voltage of 1.31 V at 1.5A and 25°C, as specified in the Electrical Specifications table. At 125°C, VF drops to 1.09 V max due to semiconductor physics. These values directly impact conduction loss calculation (Pcond = IF × VF) and thermal design - e.g., 1.31 V × 1.5 A = 1.97 W dissipation at room temperature.
Does HS15KLWH have a defined reverse recovery time (trr)?
Yes, the HS15KLWH has a maximum reverse recovery time of 75 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter is measured per JEDEC standards and reflects switching speed critical for minimizing losses in snubber and high-frequency freewheeling applications. Slower alternatives like general-purpose rectifiers typically exceed 500 ns.
What package type does HS15KLWH use, and what are its key mechanical features?
The HS15KLWH uses the SOD-123W package: a low-profile surface-mount case with matte tin-plated leads, cathode polarity marked by a band, and UL 94V-0 compliant molding compound. Its mechanical data confirms J-STD-020 moisture sensitivity Level 1 (no bake required), JESD201 Class 2 whisker resistance, and approximate weight of 0.016 g - all supporting high-yield automated assembly in automotive manufacturing.
