Product details

Overview

S3D from Taiwan Semiconductor is a 200 V, 3 A surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring 100 A surge capability, 1.15 V max forward voltage at 3 A, and 1500 ns reverse recovery time; used in SMPS input rectification stages where high reliability and thermal robustness are required.

For engineers reviewing the S3D datasheet, S3D pinout, S3D application, or S3D equivalent, key selection criteria include repetitive peak reverse voltage (200 V), average forward current (3 A), junction-to-lead thermal resistance (13 °C/W), and DO-214AB mechanical compatibility with automated assembly lines.

Technical Context

The S3D is a single-die, glass-passivated standard recovery rectifier optimized for switching-mode power supplies operating up to 150 °C junction temperature. Its 200 V V_RRM, 100 A I_FSM (8.3 ms), and 13 °C/W R_θJL support high-efficiency, compact AC/DC front-end designs.

Electrical behavior is defined by a typical junction capacitance of 60 pF at 4 V reverse bias and reverse leakage ≤10 µA at 25 °C - enabling stable operation under transient overvoltage conditions while maintaining low conduction loss.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - maximum repetitive reverse voltage before breakdown; sets safe operating limit for bridge or single-diode rectifier inputs
I_F	3 A - continuous average forward current at T_L = 75 °C; defines steady-state power handling in thermally constrained layouts
I_FSM	100 A - non-repetitive surge current (8.3 ms half-sine); withstands inrush and line-transient stress without failure
V_F	≤1.15 V - max forward voltage at 3 A and 25 °C; directly determines conduction loss and thermal load in high-duty-cycle operation
t_rr	1500 ns - reverse recovery time under IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; impacts switching loss and EMI in 50–100 kHz SMPS topologies
R_θJL	13 °C/W - junction-to-lead thermal resistance; enables direct heatsinking via PCB copper pour or metal-core substrate
Junction Temp	−55 to +150 °C - operational range defining suitability for industrial ambient environments and sealed enclosures

Pinout & Package

DO-214AB (SMC) surface-mount package with cathode-indicated band; matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance; UL 94V-0 molding compound; weight ≈ 0.210 g.

Pin/Terminal	Circuit Role	Design Meaning

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor MUR320	Same V_RRM (200 V), same I_F (3 A), but faster t_rr = 75 ns; higher V_F = 1.3 V typical	Better suited for higher-frequency (>200 kHz) PFC or resonant converters where switching loss dominates	Select MUR320 only when reduced EMI and lower stored charge outweigh higher conduction loss

FAQ

What is the maximum repetitive peak reverse voltage rating for the S3D?

The S3D has a maximum repetitive peak reverse voltage (V_RRM) of 200 V, as confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version O2301). This rating defines the highest reverse voltage the S3D can block repeatedly without breakdown under normal operating conditions and is critical for selecting appropriate safety margins in rectifier circuits.

Does the S3D have a specified reverse recovery time, and how is it measured?

Yes, the S3D has a 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, per the Electrical Specifications section of the Taiwan Semiconductor datasheet. This value reflects its standard recovery behavior and informs EMI and switching loss estimation in 50–100 kHz SMPS designs.

Is the S3D RoHS and halogen-free compliant?

Yes, the S3D is explicitly stated as RoHS Compliant and Halogen-free in the FEATURES section of the Taiwan Semiconductor documentation (Version O2301). These compliance statements confirm adherence to EU Directive 2011/65/EU and IEC 61249-2-21, supporting environmental certification of end products.

What is the thermal resistance from junction to lead for the S3D, and why does it matter?

The S3D has a junction-to-lead thermal resistance (R_θJL) of 13 °C/W, per the Thermal Performance table. This parameter quantifies how effectively heat transfers from the silicon die to the device leads, enabling direct thermal coupling to PCB copper pours or metal-core substrates - a key factor in managing power dissipation in space-constrained power supplies.

What marking code appears on the S3D device body?

The S3D is marked with the code "S3D" on its molded plastic body, as shown in the Marking Diagram section of the Taiwan Semiconductor datasheet (Version O2301). This marking is located adjacent to the cathode band and is used for visual identification and traceability during assembly and inspection.
