Taiwan Semiconductor Corporation S2GHR5G

Overview

S2GHR5G from Taiwan Semiconductor is a 2 A, 400 V repetitive peak reverse voltage (V_RRM) standard surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring glass-passivated junction, low forward voltage drop (≤1.15 V at 2 A), and high surge current capability (50 A I_FSM). It is used in AC/DC front-end rectification for compact switching mode power supplies.

For engineers reviewing the S2GHR5G datasheet, S2GHR5G pinout, S2GHR5G application, or S2GHR5G equivalent, key selection factors include its 400 V V_RRM, 1500 ns reverse recovery time, 30 pF junction capacitance, moisture sensitivity level 1 rating, and compatibility with automated SMT placement on SMB footprint layouts.

Technical Context

This device is a single-die, unidirectional standard recovery rectifier optimized for cost-sensitive, medium-voltage DC power conversion where fast recovery is not required. Its 1500 ns trr and 1.15 V VF reflect trade-offs favoring thermal robustness and surge tolerance over switching speed.

Thermal performance is defined by R_θJL = 16 °C/W and R_θJA = 53 °C/W, supporting continuous 2 A operation up to 150 °C junction temperature when mounted on standard PCB copper areas per JEDEC standards.

FAQ

What is the maximum junction temperature rating for the S2GHR5G?

The S2GHR5G has a maximum junction temperature (T_J) rating of +150 °C, validated per absolute maximum ratings table. This allows operation in high-ambient environments such as enclosed LED drivers or industrial power modules. Derating curves confirm 2 A continuous current is sustainable up to this limit when mounted on ≥1 cm² of 2-oz copper per JEDEC 51-14 guidelines. Thermal design must account for R_θJA = 53 °C/W under standard test conditions.

Does the S2GHR5G meet RoHS and halogen-free requirements?

Yes, the S2GHR5G complies with EU RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below 1000 ppm. Certificate of Compliance is available upon request, and all production lots undergo quarterly third-party testing to verify material declarations.

What is the reverse recovery time (t_rr) specification for the S2GHR5G?

The S2GHR5G has a reverse recovery time (t_rr) of 1500 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per JEDEC test conditions. This value reflects its standard recovery behavior and makes it unsuitable for high-frequency (>100 kHz) topologies but well-suited for 25–50 kHz flyback or forward converters where low conduction loss is prioritized over switching speed.

Is the S2GHR5G suitable for automated SMT assembly?

Yes, the S2GHR5G is explicitly designed for automated placement, with DO-214AA (SMB) package geometry, matte tin-plated leads meeting J-STD-002 solderability, and moisture sensitivity level 1 per J-STD-020. No pre-bake is required, and the device supports standard reflow profiles (peak 260 °C, 10 s max). Lead coplanarity is guaranteed ≤0.15 mm, enabling >99.9% placement yield at leading EMS providers.

What does the "HR5G" suffix in S2GHR5G indicate?

The "HR5G" suffix in S2GHR5G denotes Taiwan Semiconductor's internal revision and environmental code: "H" indicates halogen-free construction, "R5" specifies tape-and-reel packaging (3,000 units per reel), and "G" identifies green compound (RoHS-compliant molding material). This suffix is not part of the core S2G family designation but confirms compliance and packaging format for procurement and logistics tracking.
