Taiwan Semiconductor Corporation HS3J

Overview

HS3J from Taiwan Semiconductor is a 600 V repetitive peak reverse voltage, 3 A average forward current, surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring 1.7 V max forward voltage at 3 A and 75 ns reverse recovery time - used for high-frequency freewheeling and output rectification in switching-mode power supplies for telecom infrastructure.

For engineers reviewing the HS3J datasheet, HS3J pinout, HS3J application, or HS3J equivalent, key selection criteria include its 600 V V_RRM, 150 A I_FSM, 50 pF junction capacitance at 1 MHz, -55°C to +150°C operating temperature range, and DO-214AB mechanical compatibility with automated SMT assembly lines.

Technical Context

This is a single-die, glass-passivated, standard recovery silicon rectifier optimized for high-efficiency, medium-voltage switching applications. It delivers low conduction loss via 1.7 V max V_F at rated current and maintains fast switching behavior with 75 ns t_rr, enabling use in 100–500 kHz SMPS topologies without excessive switching loss.

The device uses matte tin-plated leads compliant with J-STD-002, meets JESD201 Class 2 whisker resistance, and is housed in UL 94V-0 mold compound. Its cathode band polarity marking and moisture sensitivity level 1 rating support robust reflow and long-term reliability in industrial power converters.

FAQ

What is the maximum junction temperature rating for HS3J?

The HS3J has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings table in the official TSC datasheet Version K2102. This allows operation in high-ambient environments such as enclosed server PSUs or industrial control cabinets. Derating curves confirm usable current capacity down to 1.8 A at 125°C ambient with standard PCB layout, and HS3J must be mounted on ≥100 mm² copper area to achieve this rating reliably.

Does HS3J support lead-free reflow soldering?

Yes, HS3J supports lead-free reflow soldering per J-STD-002 specifications, with matte tin-plated leads and moisture sensitivity level 1 (MSL-1) rating. No pre-bake is required prior to reflow, and the device withstands peak temperatures up to 260°C for 10 seconds. The UL 94V-0 mold compound ensures no outgassing or delamination during standard Pb-free thermal profiles used in telecom and industrial SMT lines.

What is the reverse recovery time (t_rr) of HS3J and how is it measured?

The HS3J has a reverse recovery time (t_rr) of 75 ns maximum, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A per the TSC K2102 datasheet. This value reflects performance in hard-switched topologies and is validated using standardized test circuits shown in Figure 6 of the datasheet. It is higher than HS3G (50 ns) due to optimized carrier lifetime for lower V_F trade-off, making HS3J ideal for 200–400 kHz applications.

Can HS3J be used as a direct replacement for HS3G in existing designs?

HS3J can replace HS3G in most designs where 600 V V_RRM suffices instead of 400 V, but design validation is required due to differences: HS3J has higher V_F (1.7 V vs. 1.3 V), lower C_J (50 pF vs. 80 pF), and longer t_rr (75 ns vs. 50 ns). Thermal and EMI behavior may shift; verify temperature rise and ringing in the specific circuit. Both share identical DO-214AB package and pinout, so no PCB change is needed.

Is HS3J halogen-free and RoHS compliant?

Yes, HS3J is halogen-free per IEC 61249-2-21 and RoHS compliant per EU Directive 2011/65/EU, confirmed in the "Features" section of the TSC HS3A–HS3M datasheet Version K2102. The molding compound contains no brominated or chlorinated flame retardants, and lead content is below 1000 ppm.
