Taiwan Semiconductor Corporation HS5A V7G

Overview

HS5A V7G from Taiwan Semiconductor is a 5A, 50V glass-passivated surface-mount 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. It serves as a high-efficiency freewheeling and output rectifier in switching-mode power supplies for telecom and computing equipment.

For engineers reviewing the HS5A V7G datasheet, HS5A V7G pinout, HS5A V7G application, or HS5A V7G equivalent, key selection criteria include repetitive peak reverse voltage (50V), thermal resistance (60°C/W), junction capacitance (80pF), reverse recovery time (≤50ns), and moisture sensitivity level (J-STD-020 Level 1).

Technical Context

This single-die standard recovery rectifier uses glass-passivated junction technology to achieve low forward voltage drop and stable high-temperature operation up to 150°C junction temperature. Its DO-214AB (SMC) package supports automated placement and meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance requirements.

The device exhibits 80pF typical junction capacitance at 1MHz/4V and ≤50ns reverse recovery time under 0.5A forward / 1.0A reverse test conditions. Reverse leakage remains ≤10µA at 25°C and ≤250µA at 125°C, enabling reliable performance in high-frequency DC-DC converters and offline SMPS.

FAQ

What is the maximum junction temperature rating for HS5A V7G?

The HS5A V7G has a maximum junction temperature (TJ MAX) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating enables reliable operation in thermally demanding environments such as enclosed telecom power modules. Derating curves confirm usable current capacity down to 0A at 150°C ambient with standard PCB copper. The HS5A V7G must be operated within this limit to ensure long-term reliability and avoid parametric shift.

Does HS5A V7G have a specified reverse recovery time (trr)?

Yes, the HS5A V7G has a maximum reverse recovery time (trr) of 50 ns, measured under IF = 0.5A, IR = 1.0A, and Irr = 0.25A conditions. This value is confirmed in the Electrical Specifications table of the Taiwan Semiconductor datasheet (Version K2102). The HS5A V7G's ≤50ns trr supports efficient operation in 100–500 kHz switching applications, distinguishing it from general-purpose rectifiers with trr >100ns.

Is HS5A V7G compatible with lead-free reflow soldering processes?

Yes, the HS5A V7G features matte tin-plated leads compliant with J-STD-002 solderability standards and is qualified for lead-free reflow profiles (peak temperature up to 260°C). Its J-STD-020 moisture sensitivity level is Level 1, meaning it can be placed directly onto PCBs without pre-baking-even after extended storage. The HS5A V7G's construction ensures robust intermetallic formation and joint integrity under IPC-A-610 Class 2/3 requirements.

What does the "V7G" suffix in HS5A V7G indicate?

The "V7G" suffix in HS5A V7G denotes Taiwan Semiconductor's internal date code and assembly lot identifier: "V" = year code (2025), "7" = week code (week 7), and "G" = factory code (Tainan fab). It does not affect electrical specifications-HS5A V7G shares identical absolute maximum ratings, electrical characteristics, and mechanical dimensions with all HS5A variants. The HS5A V7G is fully interchangeable with other HS5A date codes in design and production.

Can HS5A V7G replace a Schottky diode in a 50V application?

The HS5A V7G can replace a Schottky diode only if the application tolerates higher forward voltage (≤1.00V vs. typical 0.4–0.6V for Schottkys) and requires ≥50V blocking with better high-temperature stability. Unlike Schottkys, the HS5A V7G has measurable trr (≤50ns) and higher IR at elevated temperature. For low-loss 50V designs, MBR540 is a Schottky alternative-but HS5A V7G offers superior surge robustness and thermal margin. System-level validation of efficiency and thermal rise is required before substituting HS5A V7G for Schottky diodes.
