Product details
Overview
HS15GLWH from Taiwan Semiconductor is a 1.5A, 400V glass-passivated surface-mount rectifier in SOD-123W package, featuring 0.93V max forward voltage at 1.5A/25°C, 50ns reverse recovery time, and AEC-Q101 qualification for automotive power conversion circuits.
For engineers reviewing the HS15GLWH datasheet, HS15GLWH pinout, HS15GLWH application, or HS15GLWH equivalent, this device serves as a high-reliability, low-profile freewheeling and snubber diode in DC-DC converters, car lighting systems, and automotive-grade power supplies where thermal performance (RθJA = 84°C/W) and moisture resistance (J-STD-020 Level 1) are critical.
Technical Context
The HS15GLWH is a single-die, unidirectional silicon rectifier optimized for fast switching and low conduction loss. Its 400V VRRM, 40A IFSM, and 150°C maximum junction temperature support robust operation under transient overcurrent and elevated ambient conditions.
Thermal design is enabled by its SOD-123W package with matte tin-plated leads and 43°C/W junction-to-lead resistance. The device exhibits 22pF junction capacitance at 1MHz/4V, supporting stable high-frequency rectification in compact automotive power stages.

| RθJA | 84 °C/W - Thermal resistance to ambient on standard 5mm × 5mm Cu pad; enables derating up to 1.1A at 70°C ambient |
| Junction temp | −55°C to +150°C - Wide operating range meets under-hood automotive requirements per AEC-Q101 stress testing |
| CJ | 22 pF @ 1MHz/4V - Low junction capacitance preserves signal integrity and reduces capacitive coupling in snubber networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semi MUR15040 | 400V VRRM, 1.5A IF, but TO-277 package (larger footprint, higher RθJA = 100°C/W) | Requires PCB layout revision due to different pad geometry and thermal pad requirements | Prefer HS15GLWH when board space or thermal budget is constrained |
| Vishay V15P4 | 400V VRRM, 1.5A IF, SOD-123W package, but not AEC-Q101 qualified and 75ns trr | Limited to non-safety-critical consumer or industrial use; unsuitable for ASIL-relevant lighting or power modules | Choose HS15GLWH for automotive production programs requiring certified reliability |
Compared with MUR15040 and V15P4, the HS15GLWH delivers identical voltage/current ratings in a smaller, thermally superior, and automotive-qualified package-making it the optimal choice for space-limited, high-reliability 12V–48V automotive power designs.

FAQ
What is the peak repetitive reverse voltage rating for HS15GLWH?
The HS15GLWH has a peak repetitive reverse voltage (VRRM) rating of 400 V. This value is specified in the Absolute Maximum Ratings table and verified across production lots per JESD22-A106. It defines the maximum reverse-bias voltage the device can block continuously without breakdown. Operation above 400 V risks irreversible avalanche failure. Derating to 320 V is recommended for long-term reliability in high-temperature environments.
Is HS15GLWH suitable for automotive applications requiring AEC-Q101 certification?
Yes, HS15GLWH is explicitly AEC-Q101 qualified per the manufacturer's datasheet Version A2103. It has passed all required stress tests including high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress test (UHAST). This certification confirms suitability for automotive power electronics such as LED drivers, body control modules, and start-stop system supplies.
What is the forward voltage drop of HS15GLWH at 1.5A and 25°C?
The forward voltage drop (VF) of HS15GLWH is guaranteed ≤0.95 V at 1.5 A and 25°C, with typical value of 0.93 V. This specification is measured under pulsed conditions (PW = 0.3 ms) and reflects conduction loss under nominal operating conditions. At 125°C, VF decreases to ≤0.80 V due to negative temperature coefficient of silicon diodes.
Does HS15GLWH have a defined reverse recovery time, and what is its value?
Yes, HS15GLWH has a specified reverse recovery time (trr) of ≤50 ns. This parameter is measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per JEDEC standards. The fast trr enables efficient operation in high-frequency switching applications such as 300 kHz–1 MHz DC-DC converters, reducing switching losses and EMI generation.
What package type does HS15GLWH use, and what are its key mechanical features?
HS15GLWH uses the SOD-123W surface-mount package. Key mechanical features include a low profile (max 1.3 mm height), glass passivated chip junction, matte tin-plated solderable leads compliant with J-STD-002, J-STD-020 Level 1 moisture sensitivity, and UL 94V-0 flammability-rated molding compound. Polarity is indicated by a cathode band.
