Taiwan Semiconductor Corporation S2JHR5G

Overview

S2JHR5G from Taiwan Semiconductor is a 600 V, 2 A standard surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring glass-passivated junction, 50 A surge capability, and 1.15 V max forward voltage at 2 A - used in AC/DC front-end rectification for offline SMPS and LED drivers.

For engineers reviewing the S2JHR5G datasheet, S2JHR5G pinout, S2JHR5G application, or S2JHR5G equivalent, key selection criteria include repetitive peak reverse voltage (600 V), thermal resistance (R_θJA = 53 °C/W), moisture sensitivity level (MSL 1), and RoHS/halogen-free compliance per IEC 61249-2-21.

Technical Context

This standard recovery rectifier uses a single-die silicon PN junction with glass passivation for robustness against humidity and mechanical stress. Its 1500 ns reverse recovery time (trr) and 30 pF junction capacitance at 4 V bias indicate suitability for <100 kHz switching applications where low cost and reliability outweigh ultra-fast recovery needs.

The device operates across –55 °C to +150 °C junction temperature range, with thermal performance defined by R_θJL = 16 °C/W and R_θJA = 53 °C/W. Cathode polarity is marked by a visible band on the DO-214AA molded case, and terminals are matte tin-plated for J-STD-002 solderability.

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, serving industrial, computing, and consumer markets since 1979.

The S2A–S2V series was designed specifically for cost-effective, high-reliability AC/DC front-end rectification in space-constrained surface-mount power supplies - emphasizing manufacturability, thermal stability, and regulatory compliance.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for S2JHR5G?

The S2JHR5G has a V_RRM of 600 V, confirmed in the Taiwan Semiconductor S2A–S2V family datasheet (Version N2102). This rating allows safe operation with 424 V RMS input - covering universal 85–265 VAC mains with adequate transient margin. The value is laser-marked as "S2J" on the device body and applies strictly to the S2JHR5G variant within the series.

Is S2JHR5G suitable for reflow soldering without moisture preconditioning?

Yes, the S2JHR5G is rated MSL Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30 °C/60 % RH and placed directly into reflow without baking. This eliminates pre-reflow dry storage or bake cycles, streamlining high-volume SMT manufacturing - a verified specification documented in the mechanical data section of the official TSC datasheet.

What is the forward voltage drop of S2JHR5G at rated current?

The S2JHR5G exhibits a maximum forward voltage (V_F) of 1.15 V at 2 A and 25 °C junction temperature, per the electrical specifications table. At elevated temperatures (e.g., 125 °C), V_F decreases slightly due to semiconductor physics, but system-level thermal design must ensure average power dissipation remains within R_θJA-limited boundaries for the S2JHR5G.

Does S2JHR5G have halogen-free and RoHS-compliant construction?

Yes, the S2JHR5G meets both RoHS Directive 2011/65/EU and halogen-free requirements per IEC 61249-2-21, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. The molding compound, lead finish, and internal die attach materials are all certified compliant - critical for export to EU, China, and other regulated markets.

What is the reverse recovery time (t_rr) of S2JHR5G, and how does it affect circuit design?

The S2JHR5G has a typical reverse recovery time (t_rr) of 1500 ns under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A test conditions. This standard recovery characteristic makes it appropriate for flyback and forward converters operating below 100 kHz, but not for high-frequency resonant or active-clamp topologies where fast recovery diodes are mandatory - a key constraint confirmed in the ELECTRICAL SPECIFICATIONS table.
