Product details

Overview

HS2G-T from Taiwan Semiconductor is a 2 A, 400 V repetitive peak reverse voltage (V_RRM) surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring 1.02 V forward voltage at 2 A and 25°C, 50 A surge current capability, and 15 pF junction capacitance - used in DC-DC converters and switching-mode power supplies.

For engineers reviewing the HS2G-T datasheet, HS2G-T pinout, HS2G-T application, or HS2G-T equivalent, key selection criteria include its 400 V V_RRM, low 1.02 V V_F at rated current, 50 A I_FSM, thermal resistance of 20 °C/W (junction-to-lead), and SMB package compatibility with automated assembly.

Technical Context

This is a single-die, glass-passivated, high-efficiency standard recovery rectifier optimized for switching-mode power conversion. It delivers stable conduction up to 150 °C junction temperature with low reverse leakage (≤5 µA at 25 °C, ≤350 µA at 125 °C) and fast reverse recovery (t_rr ≤ 50 ns).

The device uses a planar junction structure with matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 1 whisker resistance. Its DO-214AA (SMB) package meets UL 94V-0 flammability rating and moisture sensitivity level 1 per J-STD-020.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - maximum repetitive reverse blocking voltage without breakdown
I_F	2 A - continuous average forward current at T_L = 75 °C on PCB
V_F @ 2 A, 25 °C	1.02 V (max 1.40 V) - forward conduction loss impacting efficiency and thermal rise
I_FSM (8.3 ms)	50 A - non-repetitive surge current handling during power-up or fault transients
t_rr	≤ 50 ns - reverse recovery time limiting switching losses in high-frequency SMPS
C_J @ 1 MHz, 4 V	15 pF - junction capacitance affecting high-frequency noise and EMI behavior
R_θJL	20 °C/W - thermal resistance from junction to lead, critical for PCB copper pad design

Pinout & Package

Package: DO-214AA (SMB), surface-mount, cathode indicated by band. Leads are matte tin-plated, solderable per J-STD-002, with polarity clearly marked.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to lower-potential side in rectification path; requires adequate trace width for 2 A continuous

Equivalent & Alternatives

The following parts are listed as comparable options for similar rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R04	Same 2 A / 400 V rating; slightly higher V_F (1.30 V max @ 2 A); t_rr = 45 ns; TO-220AC package	Requires through-hole mounting and larger board area; better thermal dissipation in heatsinked designs	Choose STTH2R04 only when higher thermal mass or legacy through-hole assembly is required
SS24-E3/57T	2 A / 40 V rating; Schottky architecture; V_F = 0.52 V; no reverse recovery; but insufficient V_RRM for 400 V applications	Not suitable for line-voltage or high-V_R rectification; limited to low-voltage DC-DC outputs	SS24-E3/57T is not a functional substitute for HS2G-T due to 40 V V_RRM limitation

Compared with STTH2R04 and SS24-E3/57T, the HS2G-T uniquely balances 400 V blocking, SMB surface-mount compatibility, and 50 ns recovery in a cost-effective discrete rectifier - making it optimal for space-constrained, medium-voltage SMPS where leaded alternatives add assembly cost and Schottky devices lack voltage rating.

FAQ

What is the maximum junction temperature rating for the HS2G-T?

The HS2G-T has a maximum junction temperature (T_J) of +150 °C, verified per absolute maximum ratings in the official TSC datasheet. This rating enables reliable operation in enclosed industrial power supplies where ambient temperatures reach 70–85 °C, provided thermal design maintains junction temperature below this limit using the specified R_θJL = 20 °C/W and appropriate PCB copper area. The HS2G-T must not be operated beyond this limit to ensure long-term reliability.

Does the HS2G-T have a specified reverse recovery time (t_rr)?

Yes, the HS2G-T has a specified reverse recovery time of ≤50 ns under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_RR = 0.25 A, as documented in the TSC electrical specifications table. This value is confirmed for HS2G-T (and HS2D-T) and is distinct from the 75 ns rating for higher-voltage variants (HS2J-T through HS2M-T). The HS2G-T's 50 ns t_rr supports efficient operation in 100–500 kHz switching converters.

Is the HS2G-T RoHS and halogen-free compliant?

Yes, the HS2G-T is RoHS compliant and halogen-free in accordance with IEC 61249-2-21, as explicitly stated in the TSC product documentation. The molding compound and plating meet these requirements, and the device carries the "G" suffix in its marking code (HS2G) to denote green compound. This compliance applies directly to the HS2G-T and is verified across its full production lot traceability.

What is the forward voltage (V_F) of the HS2G-T at 2 A and 125 °C?

The forward voltage of the HS2G-T is 0.87 V (typical) and 1.04 V (maximum) at I_F = 2 A and T_J = 125 °C, per the TSC electrical specifications table. This elevated-temperature V_F is lower than at 25 °C (1.02 V typ), reflecting the negative temperature coefficient of silicon diodes. Designers must use the 1.04 V max value for worst-case thermal analysis in the HS2G-T.

What does the "-T" suffix indicate in HS2G-T?

The "-T" suffix in HS2G-T denotes tape-and-reel packaging: 3,000 units per reel, compatible with automated SMT placement equipment. This packaging format is standard for the entire HS2x-T series and is specified in the TSC ordering information section. The HS2G-T is not offered in bulk or ammo-pack formats; all commercial shipments of HS2G-T use the -T reel configuration.
