Taiwan Semiconductor Corporation HS5A V6G

Overview

HS5A V6G from Taiwan Semiconductor is a 5A, 50V glass-passivated surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring 150A surge rating, 1.00V max forward voltage at 5A/25°C, and 10µA max reverse leakage at 25°C, used for high-frequency rectification in switching-mode power supplies.

For engineers reviewing the HS5A V6G datasheet, HS5A V6G pinout, HS5A V6G application, or HS5A V6G equivalent, key selection criteria include repetitive peak reverse voltage (50V), thermal resistance (60°C/W), junction capacitance (80pF), reverse recovery time (≤50ns), and RoHS/halogen-free compliance for industrial and telecom power designs.

Technical Context

This single-die, unidirectional silicon rectifier employs glass passivation for enhanced reliability and moisture resistance (J-STD-020 Level 1). Its low-profile DO-214AB (SMC) package supports automated placement and meets UL 94V-0 flammability requirements.

The device operates across -55°C to +150°C junction temperature range with 60°C/W junction-to-ambient thermal resistance. Electrical behavior is characterized by fast recovery (≤50ns), low forward voltage drop (≤1.00V @ 5A), and tight reverse leakage control (≤10µA @ 25°C).

FAQ

What is the maximum junction temperature rating for HS5A V6G?

The HS5A V6G has a maximum junction temperature (TJ max) of +150°C, allowing reliable operation in high-temperature environments such as enclosed power supplies or under-hood automotive modules. This rating is validated per JEDEC standards and supports derated current operation up to 125°C ambient with appropriate PCB copper area. The HS5A V6G maintains stable electrical parameters within this range when mounted on minimum recommended pad layout.

Does HS5A V6G meet RoHS and halogen-free requirements?

Yes, HS5A V6G is fully RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below 1000 ppm. These specifications are verified through TSC's certified material declarations and third-party lab testing, ensuring compliance for export to EU, China, and other regulated markets. HS5A V6G documentation includes full substance declaration reports.

What is the reverse recovery time (trr) specification for HS5A V6G?

The HS5A V6G has a maximum reverse recovery time (trr) of 50 ns, measured under IF = 0.5A, IR = 1.0A, and Irr = 0.25A conditions. This fast recovery characteristic minimizes switching losses and voltage overshoot in high-frequency converters operating above 100 kHz. The HS5A V6G achieves this performance via optimized silicon doping and junction design, distinguishing it from general-purpose rectifiers with trr > 100 ns.

Is HS5A V6G pin-compatible with other DO-214AB rectifiers like MUR550?

No, HS5A V6G is not pin-compatible with MUR550 because MUR550 uses DO-214AC (SMA) package, which has smaller body dimensions and different lead spacing. HS5A V6G uses DO-214AB (SMC) with 7.11 mm x 6.22 mm outline and 2.54 mm lead pitch. While both are cathode-banded surface-mount diodes, PCB land patterns are not interchangeable. HS5A V6G shares mechanical compatibility only with other DO-214AB devices such as VS-5EYH05-M3.

What is the forward voltage (VF) of HS5A V6G at rated current?

The HS5A V6G exhibits a maximum forward voltage (VF) of 1.00 V at 5A DC and 25°C junction temperature, measured under pulse conditions (PW = 0.3 ms). At elevated temperatures (125°C), VF decreases slightly due to negative temperature coefficient of silicon. This low VF directly reduces conduction losses in power stage designs-e.g., 5W dissipation at 5A becomes 5.0W instead of 5.5W with a 1.10V diode-making HS5A V6G especially valuable in efficiency-critical applications.
