Taiwan Semiconductor Corporation HS5G

Overview

HS5G from Taiwan Semiconductor is a 400 V repetitive peak reverse voltage, 5 A average forward current, surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring 1.30 V max forward voltage at 5 A and 50 ns max reverse recovery time - used for high-frequency rectification in switching-mode power supplies.

For engineers reviewing the HS5G datasheet, HS5G pinout, HS5G application, or HS5G equivalent, key selection criteria include its 400 V VRRM rating, 1.30 V VF at 5 A, 50 ns trr, 80 pF junction capacitance at 1 MHz / 4.0 V reverse bias, and DO-214AB thermal performance (RθJA = 60 °C/W).

Technical Context

The HS5G is a single-die, glass-passivated, standard recovery silicon rectifier optimized for high-frequency operation in SMPS and DC-DC converters. Its 50 ns reverse recovery time and 80 pF junction capacitance at 1 MHz/4.0 V support efficient switching up to several hundred kHz.

Designed for surface-mount assembly with matte tin-plated leads (J-STD-002 compliant), it operates across –55 °C to +150 °C junction temperature range and meets JESD201 Class 2 whisker resistance and RoHS/halogen-free requirements.

FAQ

What is the maximum repetitive peak reverse voltage (VRRM) for HS5G?

The HS5G has a VRRM rating of 400 V, meaning it can block up to 400 V of reverse voltage repeatedly without breakdown. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version K2102) and is specific to the HS5G variant - not extrapolated from adjacent part numbers like HS5F (300 V) or HS5J (600 V). The HS5G must be selected only where system-level reverse voltage stresses remain below this threshold.

What is the forward voltage drop (VF) of HS5G at 5 A and 25°C?

The HS5G exhibits a maximum forward voltage drop of 1.30 V at 5 A and TJ = 25°C, per the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents worst-case conduction loss for thermal design. At elevated junction temperatures (e.g., 125°C), VF decreases slightly, but system-level derating must follow the Forward Current Derating Curve in the datasheet. The HS5G's VF is higher than Schottky alternatives but appropriate for its 400 V rating.

Does HS5G have a specified junction capacitance, and under what conditions?

Yes, the HS5G has a typical junction capacitance (CJ) of 80 pF, measured at 1 MHz and 4.0 V reverse bias - explicitly stated in the Electrical Specifications table. This parameter is critical for high-frequency EMI modeling and snubber network design. It is distinct from HS5J–HS5M variants (50 pF), confirming voltage-dependent capacitance behavior across the HS5x family. The HS5G's 80 pF value must be used in AC analysis for accurate simulation.

What is the reverse recovery time (trr) of HS5G, and how is it tested?

The HS5G has a maximum reverse recovery time (trr) of 50 ns, tested under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the datasheet's Electrical Specifications. This test condition reflects realistic commutation in medium-frequency SMPS. The HS5G's trr is faster than HS5J–HS5M (75 ns) but slower than ultrafast rectifiers - making it suitable for 200–500 kHz operation. Designers must verify layout parasitics do not degrade effective trr in their application.

Is HS5G compatible with lead-free reflow soldering processes?

Yes, the HS5G features matte tin-plated leads compliant with J-STD-002 for solderability and is rated J-STD-020 Level 1 for moisture sensitivity - meaning it can be placed directly into lead-free reflow (peak ~260°C) without baking. Its DO-214AB (SMC) package uses UL 94V-0 molding compound, and the device is RoHS and halogen-free per IEC 61249-2-21. No special handling is required before assembly, unlike higher-MSL components.
