Taiwan Semiconductor Corporation HS5A R7G

Overview

HS5A R7G from Taiwan Semiconductor is a 5A, 50V glass-passivated surface-mount rectifier 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 freewheeling in SMPS power supplies.

For engineers reviewing the HS5A R7G datasheet, HS5A R7G pinout, HS5A R7G application, or HS5A R7G equivalent, key selection criteria include repetitive peak reverse voltage (50V), thermal resistance (60°C/W), junction temperature range (−55°C to +150°C), cathode-band polarity marking, and tape-and-reel packaging (3,000 pcs).

Technical Context

This single-die standard recovery rectifier uses glass-passivated PN junction technology optimized for switching-mode power conversion. Its 50V V_RRM, 150A I_FSM, and 50ns typical reverse recovery time support efficient energy transfer in DC-DC converters and flyback snubbers.

The DO-214AB (SMC) package provides low-profile mounting with matte tin-plated leads compliant to J-STD-002 solderability and JESD 201 Class 2 whisker resistance. Moisture sensitivity level is rated at Level 1 per J-STD-020.

FAQ

What is the maximum junction temperature rating for HS5A R7G?

The HS5A R7G has a maximum junction temperature (T_J) rating of +150°C, with an operating range from −55°C to +150°C. This allows reliable operation in thermally demanding environments such as enclosed power supplies or high-ambient industrial settings. Thermal design must respect the 60°C/W junction-to-ambient resistance and ensure adequate copper pour or heatsinking to maintain HS5A R7G below this limit under full 5A load.

Does HS5A R7G have a specified reverse recovery time?

Yes, HS5A R7G has a maximum reverse recovery time (t_rr) of 50 ns under test conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This value is confirmed in the Electrical Specifications table and supports use in switching power supplies operating up to 500 kHz. The 50 ns t_rr contributes to reduced switching losses and lower EMI compared to slower general-purpose rectifiers.

Is HS5A R7G compliant with RoHS and halogen-free standards?

Yes, HS5A R7G is RoHS compliant and halogen-free per IEC 61249-2-21. The device uses lead-free matte tin plating on terminals and halogen-free molding compound meeting UL 94V-0 flammability rating. These certifications are explicitly stated in the FEATURES section and verified in the Mechanical Data and Ordering Information pages of the official Taiwan Semiconductor datasheet K2102.

What does the "R7G" suffix indicate in HS5A R7G?

The "R7G" suffix in HS5A R7G denotes Taiwan Semiconductor's internal date code and environmental compliance marking: "R7" indicates manufacturing week/year (e.g., 2027), and "G" signifies green (halogen-free) compound per IEC 61249-2-21. This suffix does not affect electrical specifications - all HS5A devices share identical V_RRM = 50 V, I_F = 5 A, and thermal parameters regardless of R7G or other suffix variants.

Can HS5A R7G be used as a direct replacement for HS5A without the R7G suffix?

Yes, HS5A R7G is functionally and electrically identical to baseline HS5A - same V_RRM, I_F, t_rr, R_θJA, and DO-214AB mechanical outline. The R7G suffix reflects updated halogen-free material content and traceable date coding, not parameter changes. Board layout, thermal design, and circuit operation remain fully compatible; no redesign or validation is required when migrating to HS5A R7G.
