Taiwan Semiconductor Corporation S2D R5G

Overview

S2D R5G from Taiwan Semiconductor is a 2 A, 200 V 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 compact switching power supplies.

For engineers reviewing the S2D R5G datasheet, S2D R5G pinout, S2D R5G application, or S2D R5G equivalent, key selection criteria include repetitive peak reverse voltage (200 V), thermal resistance (R_θJL = 16 °C/W), reverse recovery time (1500 ns), 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 and stable leakage performance across temperature. Its 1500 ns reverse recovery time and 30 pF junction capacitance reflect design trade-offs favoring cost-effective general-purpose rectification over fast-switching or ultra-low-loss operation.

The DO-214AA (SMB) package enables automated placement and provides 53 °C/W junction-to-ambient thermal resistance under standard PCB mounting. Cathode polarity is marked by a visible band, and terminals are matte tin-plated for J-STD-002 solderability.

Equivalent & Alternatives

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

Compared with MUR220 and VS-2EY20, the S2D R5G delivers optimal balance of conduction efficiency (1.15 V V_F), surge robustness (50 A I_FSM), and manufacturability (MSL 1, J-STD-002 leads), making it preferred for cost-sensitive, medium-frequency (<65 kHz) AC/DC conversion.

Availability

S2D R5G is available at Aetrix Electronics and suitable for switching mode power supplies, LED lighting drivers, and industrial DC-DC converters requiring stable component supply and J-STD-020-compliant manufacturing readiness.

Supply support for S2D R5G includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

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

The S2A–S2V series was developed to deliver standardized, high-yield surface-mount rectifiers with consistent glass-passivated junctions, optimized for automated assembly in high-volume power supply manufacturing.

FAQ

What is the maximum junction temperature rating for the S2D R5G?

The S2D R5G has a maximum junction temperature (T_JMAX) of +150 °C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet (Version N2102). This rating allows reliable operation in environments up to 75 °C ambient when mounted on standard FR-4 PCB with adequate copper area. Thermal derating must follow the forward current derating curve shown in Figure 1 of the S2D R5G datasheet.

Does the S2D R5G meet RoHS and halogen-free requirements?

Yes, the S2D R5G is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the "Features" section of the Taiwan Semiconductor S2A–S2V datasheet (Version N2102). The molding compound is UL 94V-0 rated, and terminals are matte tin-plated to meet J-STD-002 solderability standards - all confirmed in the official documentation.

What is the reverse recovery time (t_rr) specification for the S2D R5G?

The S2D R5G has a typical reverse recovery time (t_rr) of 1500 ns, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A, as specified in the "Electrical Specifications" table of the Taiwan Semiconductor S2A–S2V datasheet (Version N2102). This value is characteristic of standard recovery rectifiers and impacts switching loss in low-to-medium frequency SMPS designs.

Is the S2D R5G pin-compatible with other devices in the S2x family?

Yes, all S2x devices including S2D R5G share identical DO-214AA (SMB) package dimensions, pinout, and terminal configuration - anode and cathode leads are physically interchangeable across the series. Voltage ratings differ (e.g., S2A = 50 V, S2D = 200 V), but mechanical and soldering requirements remain fully consistent per the "Ordering Information" and "Package Outline Dimensions" sections.

What does the "R5G" suffix indicate in the S2D R5G marking?

The "R5G" suffix in S2D R5G is Taiwan Semiconductor's internal date and factory code: "R5" denotes the year-week code (e.g., 2025 Week 5), and "G" identifies the fabrication facility. This matches the "Marking Diagram" on page 5 of the S2A–S2V datasheet (Version N2102) and does not affect electrical specifications - the core device remains the S2D 200 V, 2 A rectifier.
