Taiwan Semiconductor Corporation HS5K R7G

Overview

HS5K R7G from Taiwan Semiconductor is a 800 V, 5 A high-efficiency surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring 150 A surge rating, 1.70 V max forward voltage at 5 A/25°C, and 50 pF junction capacitance - used for freewheeling and high-frequency rectification in SMPS for telecom infrastructure.

For engineers reviewing the HS5K R7G datasheet, HS5K R7G pinout, HS5K R7G application, or HS5K R7G equivalent, key selection criteria include peak reverse voltage (800 V), thermal resistance (60 °C/W), reverse recovery time (75 ns), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance for industrial power supply design.

Technical Context

This single-die, glass-passivated standard recovery rectifier operates with a maximum junction temperature of 150 °C and supports repetitive reverse voltages up to 800 V. Its low-profile DO-214AB package enables automated placement and meets UL 94V-0 flammability requirements.

The device delivers 5 A average forward current with 150 A non-repetitive surge capability (8.3 ms half-sine), exhibits 10 µA max reverse leakage at 25 °C, and achieves 75 ns reverse recovery time under IF = 0.5 A / IR = 1.0 A test conditions - optimized for switching-mode converters and inverters.

FAQ

What is the maximum junction temperature rating for HS5K R7G?

The HS5K R7G has a maximum junction temperature (TJ) rating of +150 °C, allowing reliable operation in high-ambient environments such as enclosed telecom power modules or industrial control cabinets. This rating is validated per JEDEC standards and supported by its 60 °C/W junction-to-ambient thermal resistance. Derating curves confirm usable current capacity down to 0 A at 150 °C ambient when mounted on standard PCB pads. HS5K R7G maintains specified electrical parameters within this full temperature range.

Does HS5K R7G meet RoHS and halogen-free requirements?

Yes, HS5K R7G is fully RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants, and terminal plating uses matte tin without lead or other restricted substances. These compliance attributes are verified in TSC's material declarations and certified by third-party testing labs. HS5K R7G is suitable for export to EU, China, and other regulated markets requiring full substance-level documentation.

What is the reverse recovery time (trr) specification for HS5K R7G?

The HS5K R7G has a maximum reverse recovery time (trr) of 75 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions. This value is confirmed across the full production lot and applies to all units marked HS5K R7G. The 75 ns trr enables efficient operation in 200–500 kHz switching converters while limiting switching losses and associated EMI. HS5K R7G's trr is identical to HS5J and HS5M variants in the same family.

Is HS5K R7G compatible with lead-free reflow soldering processes?

Yes, HS5K R7G is qualified for lead-free reflow soldering per J-STD-020, with a moisture sensitivity level (MSL) of Level 1 - meaning it can be stored indefinitely at ≤30 °C/60% RH without baking prior to assembly. Its matte tin-plated leads are solderable per J-STD-002, and the DO-214AB package withstands peak reflow temperatures up to 260 °C for 10 seconds. HS5K R7G supports both wave and reflow processes without delamination or voiding.

What does the 'R7G' suffix indicate in HS5K R7G?

The 'R7G' suffix in HS5K R7G denotes Taiwan Semiconductor's internal packaging and marking variant: 'R7' specifies tape-and-reel packaging (3,000 pcs per reel), and 'G' indicates green molding compound compliant with halogen-free requirements. This suffix does not affect electrical specifications - all HS5K devices share identical VRRM = 800 V, IF = 5 A, and trr = 75 ns ratings regardless of suffix. HS5K R7G is functionally identical to HS5K R7 (non-green) except for compound composition.
