Product details
Overview
HS5KH from Taiwan Semiconductor is a 800V, 5A high-efficiency surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring low forward voltage (1.70 V at 5 A), 75 ns reverse recovery time, and AEC-Q101 qualification for automotive reliability. It serves as a freewheeling or snubber diode in high-voltage DC/DC converters and car lighting systems.
For engineers reviewing the HS5KH datasheet, HS5KH pinout, HS5KH application, or HS5KH equivalent, key selection criteria include its 800 V repetitive peak reverse voltage, 150 A surge rating, glass-passivated junction, moisture sensitivity level 1, and RoHS/halogen-free compliance - all critical for automotive-grade power conversion designs.
Technical Context
This single-die standard recovery rectifier operates with a maximum junction temperature of 150 °C and exhibits a typical junction-to-ambient thermal resistance of 60 °C/W. Its 50 pF capacitance at 1 MHz and 4.0 V reverse bias supports stable high-frequency switching behavior in snubber networks.
The device uses a glass-passivated chip junction to ensure robustness against humidity and mechanical stress, and its matte tin-plated leads meet J-STD-002 solderability requirements. Polarity is marked by a cathode band on the DO-214AB body.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-5EWH08-M3 | Same DO-214AB package, 800 V VRRM, but 1.45 V VF @ 5 A and 50 ns trr; not AEC-Q101 qualified | Suitable for industrial converters where automotive qualification is unnecessary | Prefer when lower conduction loss and faster recovery outweigh automotive compliance needs |
| ON Semiconductor MUR580 | DO-214AC (SMA) package, 800 V VRRM, 1.75 V VF @ 5 A, 75 ns trr; AEC-Q101 qualified but lower IF rating (3.5 A avg) | Limited to lower-current automotive lighting or auxiliary supplies | Select only if board space allows SMA footprint and 3.5 A continuous rating suffices |
Compared with VS-5EWH08-M3 and MUR580, the HS5KH uniquely combines AEC-Q101 qualification, 5 A continuous rating, and DO-214AB mechanical robustness - making it the preferred choice for production automotive power stages requiring both reliability and thermal margin.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the HS5KH?
The HS5KH has a maximum repetitive peak reverse voltage (VRRM) of 800 V, as specified in the absolute maximum ratings table. This value is confirmed across all official documentation versions (A2102) and defines the highest reverse voltage the device can block repeatedly without breakdown. The HS5KH is part of the HS5AH–HS5MH series, where 'K' denotes the 800 V grade. This rating makes HS5KH suitable for 400–600 V DC bus applications with safety margin.
Is the HS5KH qualified for automotive applications?
Yes, the HS5KH is AEC-Q101 qualified, as explicitly stated in the FEATURES section of the official datasheet. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and unbiased highly accelerated stress test (UHAST). The HS5KH's glass-passivated junction, moisture sensitivity level 1, and RoHS/halogen-free construction further support its use in automotive under-hood and interior lighting systems.
What is the forward voltage drop (VF) of the HS5KH at 5 A and 25°C?
The forward voltage drop (VF) of the HS5KH is 1.70 V at 5 A and 25°C, per the ELECTRICAL SPECIFICATIONS table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents the conduction loss under rated continuous current. At 3 A and 25°C, VF is unspecified for HS5KH but is ≤1.35 V per the same table - confirming its high-efficiency rectification capability.
What package type does the HS5KH use, and what are its key mechanical attributes?
The HS5KH uses the DO-214AB (SMC) surface-mount package. Key mechanical attributes include a UL 94V-0 compliant molding compound, matte tin-plated leads meeting J-STD-002 solderability, polarity indicated by a cathode band, and a typical weight of 0.210 g. The package supports automated placement and has been validated for JESD 201 Class 2 whisker resistance - essential for automotive manufacturing reliability.
What is the reverse recovery time (trr) of the HS5KH, and how is it tested?
The reverse recovery time (trr) of the HS5KH is 75 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as defined in the ELECTRICAL SPECIFICATIONS table. This test method follows JEDEC-standardized waveforms and confirms the device's suitability for medium-speed switching applications such as snubbers and DC/DC output rectification where EMI and switching loss must be controlled.
