Product details

Overview

S2D from Taiwan Semiconductor is a 2 A, 200 V repetitive peak reverse voltage (V_RRM) standard surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring 1.15 V max forward voltage at 2 A and 1 µA max reverse leakage at 25°C, used in AC/DC front-end rectification for switching mode power supplies.

For engineers reviewing the S2D datasheet, S2D pinout, S2D application, or S2D equivalent, key selection criteria include its 200 V V_RRM, 50 A I_FSM surge rating, 150°C maximum junction temperature, DO-214AA mechanical compatibility, and RoHS/halogen-free compliance for industrial and adapter designs.

Technical Context

The S2D is a single-die, glass-passivated standard recovery rectifier optimized for cost-sensitive, medium-voltage AC/DC conversion. Its 1500 ns reverse recovery time (trr) and 30 pF junction capacitance reflect standard recovery behavior suitable for <100 kHz operation.

Thermally, it delivers R_θJL = 16°C/W and R_θJA = 53°C/W in DO-214AA (SMB), enabling 2 A continuous conduction with appropriate PCB copper area. Polarity is marked by cathode band on the molded case.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - Maximum non-repetitive reverse blocking voltage; defines safe operating range in bridge or single-phase rectifier inputs.
I_F	2 A - Continuous average forward current at T_A = 75°C; sets thermal derating baseline for PCB layout.
I_FSM	50 A - Peak non-repetitive surge current (8.3 ms half-sine); supports inrush tolerance in SMPS input stages.
V_F	≤1.15 V @ 2 A, 25°C - Forward drop directly impacts conduction loss and thermal load in high-duty-cycle applications.
T_J max	+150°C - Maximum junction temperature; enables operation in enclosed or high-ambient environments with proper heatsinking.
C_J	30 pF @ 1 MHz, 4 V - Junction capacitance affects high-frequency switching noise and EMI filter design in offline converters.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor MUR220	V_RRM = 200 V, I_F = 2 A, trr = 75 ns (ultrafast), V_F = 1.25 V max	Better suited for higher-frequency (<500 kHz) PFC or snubberless flyback due to faster recovery	Select MUR220 only if trr < 200 ns is required; S2D remains optimal for cost-driven 50/60 Hz–100 kHz rectification.
Vishay VS-2EY20	V_RRM = 200 V, I_F = 2 A, trr = 2000 ns, V_F = 1.1 V max, same DO-214AA package	Nearly identical performance; slightly lower V_F but longer trr increases switching loss in marginally higher-frequency use	VS-2EY20 is a direct form-fit-function alternative with minor trade-off in recovery speed; suitable for drop-in validation.

Compared with MUR220 and VS-2EY20, the S2D offers the lowest cost per unit and best balance of surge robustness (50 A I_FSM) and thermal resistance (R_θJL = 16°C/W) for mainstream SMPS and adapter designs where ultrafast recovery is unnecessary.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for the S2D?

The S2D has a V_RRM of 200 V, as specified in the absolute maximum ratings table across all versions of the S2x series. This value is fixed for the S2D variant and defines its safe reverse-bias operating limit in rectifier circuits.

Is the S2D RoHS and halogen-free compliant?

Yes, the S2D is RoHS compliant and halogen-free per IEC 61249-2-21. The device uses halogen-free molding compound and matte tin-plated leads, satisfying environmental requirements for global electronics manufacturing and export.

What package type does the S2D use, and what are its key mechanical features?

The S2D uses the DO-214AA (SMB) surface-mount package. Key mechanical features include UL 94V-0 flammability-rated molding compound, JESD 201 Class 2 whisker-tested leads, cathode polarity marking via band, and a weight of approximately 0.090 g.

What is the forward voltage (V_F) specification for the S2D at rated current?

The S2D has a maximum forward voltage of 1.15 V at I_F = 2 A and T_J = 25°C, measured under pulse conditions (PW = 0.3 ms). This value is critical for calculating conduction losses in thermal design of power supplies using the S2D.

Can the S2D replace the S2B or S2G in an existing design?

No - the S2D (200 V V_RRM) is not a direct replacement for S2B (100 V) or S2G (400 V), as V_RRM is part-number-specific within the S2x family. Substitution requires verification of reverse voltage stress margins; using S2D in place of S2G risks avalanche failure under 300+ V reverse conditions.
