Product details

Overview

HS2J-T from Taiwan Semiconductor is a 600 V, 2 A surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring 1.31 V max forward voltage at 2 A and 25°C, 75 ns reverse recovery time, and 11 pF junction capacitance - used as freewheeling or output rectification diode in switching-mode power supplies.

For engineers reviewing the HS2J-T datasheet, HS2J-T pinout, HS2J-T application, or HS2J-T equivalent, key selection criteria include peak reverse voltage rating (600 V), thermal resistance (R_θJL = 20 °C/W), low leakage (<5 µA @ 25°C), RoHS/halogen-free compliance, and SMB footprint compatibility with automated assembly.

Technical Context

The HS2J-T is a single-die, glass-passivated, standard recovery rectifier optimized for high-efficiency DC/DC conversion and switching inverters. Its 600 V V_RRM, 50 A I_FSM surge rating, and 150 °C maximum junction temperature support operation under transient overloads and elevated ambient conditions.

Electrical behavior is characterized by temperature-dependent forward voltage (1.07 V max @ 2 A, 125°C), low reverse leakage (≤350 µA @ 125°C), and fast recovery (75 ns) relative to general-purpose rectifiers - enabling reduced switching losses in medium-frequency SMPS topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - supports input rectification in 400 VAC line-derived systems with safety margin
I_F	2 A continuous - rated for sustained conduction in 20–40 W power stages
V_F (max)	1.31 V @ 2 A, 25°C - determines conduction loss and thermal rise in PCB-mounted layout
t_rr	75 ns - limits reverse recovery charge and associated switching loss in 50–200 kHz converters
C_J	11 pF @ 1 MHz, 4 V - minimizes capacitive coupling noise in high-dv/dt gate-drive or snubber circuits
R_θJL	20 °C/W - enables direct thermal path to PCB copper, supporting >1.5 W dissipation without heatsink
I_R (max)	5 µA @ 25°C - ensures low standby leakage in offline auxiliary supplies and hold-up circuits

Applications

DC/DC Converter Output Rectification	Switching Inverter Freewheeling
Use Scenario: Secondary-side rectification in isolated flyback or forward converters delivering 12–24 V at ≤2 A. IC Role / Device Role / Timing Role: Unidirectional current valve converting transformer AC output to regulated DC; operates at switching frequency (50–200 kHz). Use Value: 1.31 V V_F and 75 ns t_rr reduce conduction + recovery losses versus slower 600 V rectifiers, improving efficiency by ~0.8% at full load.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R06	600 V, 2 A, TO-220AC package; 1.7 V V_F @ 2 A, 25°C; 50 ns t_rr	Through-hole mounting; higher V_F increases conduction loss; faster t_rr reduces switching loss	Prefer when board space allows TO-220 and thermal mass improves heat spreading
SB260-E3/5BT	60 V, 2 A, DO-214AA; 0.85 V V_F @ 2 A, 25°C; Schottky architecture	Lower voltage rating limits use to <100 V circuits; near-zero t_rr eliminates recovery loss	Select only for low-V_IN DC/DC where 600 V standoff is unnecessary

Compared with STTH2R06 and SB260-E3/5BT, the HS2J-T offers optimal trade-off of 600 V rating, SMB footprint, and balanced V_F/t_rr for cost-sensitive, surface-mount SMPS designs requiring regulatory-compliant packaging and moderate switching frequencies.

FAQ

What is the peak repetitive reverse voltage rating of the HS2J-T?

The HS2J-T has a peak repetitive reverse voltage (V_RRM) rating of 600 V, verified per the manufacturer's absolute maximum ratings table. This value defines the maximum reverse-biased voltage the device can block repeatedly without breakdown. The HS2J-T must not be operated beyond this rating in any circuit, including transient spikes, to ensure long-term reliability and prevent catastrophic failure.

Does the HS2J-T have a specified reverse recovery time, and how is it measured?

Yes, the HS2J-T has a typical reverse recovery time (t_rr) of 75 ns, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This parameter is confirmed in the Electrical Specifications section of the official datasheet. The HS2J-T's t_rr directly impacts switching loss in high-frequency converters and is lower than general-purpose rectifiers but higher than ultrafast types.

What package type does the HS2J-T use, and what are its key mechanical attributes?

The HS2J-T uses the DO-214AA (SMB) surface-mount package. Key mechanical attributes include matte tin-plated leads compliant with J-STD-002, polarity indicated by a cathode band, UL 94V-0 flammability-rated molding compound, and a weight of approximately 0.090 g. The HS2J-T's SMB footprint supports automated placement and meets IPC-7351B land pattern recommendations for thermal and mechanical reliability.

Is the HS2J-T RoHS and halogen-free compliant?

Yes, the HS2J-T is RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21. These compliance statements are explicitly declared in the Features section of the official datasheet. The HS2J-T contains no brominated flame retardants or chlorine-based compounds above threshold limits, making it suitable for environmentally regulated industrial and consumer end equipment.

What is the maximum junction temperature and thermal resistance of the HS2J-T?

The HS2J-T has a maximum junction temperature (T_J) of +150 °C and a junction-to-lead thermal resistance (R_θJL) of 20 °C/W, measured on a 10 mm × 10 mm copper pad test board. These values are specified in the Thermal Performance section. Maintaining the HS2J-T within this T_J limit requires appropriate PCB copper area and airflow; exceeding it risks parametric shift or premature failure.
