Product details

Overview

S3JB-13 from Diodes Incorporated is a 600 V, 3.0 A surface-mount glass passivated rectifier diode in SMB package, designed for AC/DC input stage rectification in power supplies and adapters. It delivers 1.15 V forward voltage at 3.0 A, supports 100 A non-repetitive surge current, and operates from –65 °C to +150 °C with 10 °C/W junction-to-terminal thermal resistance.

For engineers reviewing the S3JB-13 datasheet, S3JB-13 pinout, S3JB-13 application, or S3JB-13 equivalent, key selection criteria include peak repetitive reverse voltage (600 V), average rectified output current (3.0 A @ TT = 75 °C), forward voltage drop (1.15 V @ 3.0 A), surge capability (100 A, 8.3 ms), and SMB package thermal performance for compact high-efficiency power conversion designs.

Technical Context

This device is a single-phase, half-wave silicon rectifier optimized for resistive or inductive loads at 60 Hz. Its glass passivated die construction ensures stable reverse leakage (10 µA @ 25 °C, 250 µA @ 125 °C) and robust surge immunity without requiring external snubbers in standard line-frequency applications.

The SMB package provides defined thermal path to PCB copper (R_JT = 10 °C/W on 5.0 mm² pad), enabling reliable operation under continuous 3.0 A conduction when ambient and board layout meet derating curves. Capacitive load use requires 20% current derating per specification.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - Maximum peak repetitive reverse voltage; defines safe blocking capability in 400 VAC input bridge or flyback clamp circuits.
I_O	3.0 A @ T_T = 75 °C - Continuous DC output current rating; requires heatsinking via PCB copper to sustain full load.
V_FM	1.15 V @ I_F = 3.0 A - Forward voltage drop directly impacts conduction loss (3.45 W) and thermal design margin.
I_FSM	100 A, 8.3 ms - Surge rating compatible with IEC 61000-4-5 line transient testing and cold-start inrush conditions.
R_JT	10 °C/W - Junction-to-terminal thermal resistance measured on 5.0 mm² copper pad; enables thermal modeling for board-level reliability.
C_T	40 pF @ 1 MHz, 4 V - Junction capacitance affects EMI filtering requirements and high-frequency switching noise coupling.

Pinout & Package

SMB (DO-214AA) surface-mount package: cathode marked by band on body; anode and cathode terminals only; no internal gating or control pins.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Input terminal for AC or positive half-cycle	Connects to transformer secondary or bridge input; carries full load current during conduction phase.
Cathode	Output terminal for rectified DC	Delivers unidirectional current to bulk capacitor; polarity marking (band) must align with PCB silkscreen.

Key Features

Feature	Design Value
Glass passivated die	Eliminates need for conformal coating in humid environments; maintains IR stability up to 125 °C junction temperature.
Low forward voltage (1.15 V)	Reduces conduction loss by ~12% vs. comparable 1.3 V diodes at 3 A, lowering thermal stress in enclosed adapters.
100 A surge rating	Withstands 10× rated current for 8.3 ms, meeting EN 61000-4-5 Level 3 surge immunity without external protection.
RoHS-compliant lead-free finish	Matte tin plating meets J-STD-020C Level 1 moisture sensitivity; compatible with standard reflow profiles.

Applications

AC-DC Power Adapters

Industrial SMPS Input Stages

Use Scenario: 10–65 W wall plug-in adapters for consumer electronics with universal 85–264 VAC input.

IC Role / Device Role / Timing Role: Primary-side rectifier in voltage-doubler or bridge configuration; converts AC line to pulsating DC before bulk capacitor.

Use Value: 600 V V_RRM safely handles 264 VAC × √2 + margin; 3.0 A rating supports >50 W output with <1.2 V drop at full load.

Use Scenario: 100–300 W open-frame industrial switch-mode power supplies operating in harsh ambient conditions.

IC Role / Device Role / Timing Role: Input rectifier in front-end bridge; subjected to frequent line transients and elevated ambient temperatures.

Use Value: Glass passivation and 150 °C max T_j ensure long-term reliability at 70 °C ambient; 100 A I_FSM absorbs repeated lightning-induced surges.

LED Driver Input Rectification

Appliance Control Board Power Supplies

Use Scenario: Constant-current LED drivers for commercial lighting with TRIAC dimming compatibility.

IC Role / Device Role / Timing Role: Half-wave rectifier feeding capacitive-input filter; must tolerate high crest factor and zero-crossing stress.

Use Value: Low C_T (40 pF) minimizes high-frequency noise injection into dimmer circuitry; 1.15 V V_FM reduces heat buildup near sensitive analog ICs.

Use Scenario: Embedded power supply on washing machine or HVAC control boards with limited board space and airflow.

IC Role / Device Role / Timing Role: Compact, low-profile rectifier replacing axial-leaded devices to enable automated SMT assembly.

Use Value: SMB footprint (3.6 × 4.3 mm) saves >60% board area vs. DO-41; RoHS-compliant matte tin enables lead-free reflow without dewetting.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH3L06S	600 V, 3.0 A, TO-277 package; V_F = 1.1 V @ 3 A; R_JT = 12 °C/W	Higher thermal resistance requires larger copper area; same surge rating but different footprint	Select when TO-277 mounting or higher surge margin at elevated T_j is required
ES3J	600 V, 3.0 A, SMB package; V_F = 1.7 V @ 3 A; I_FSM = 80 A	Higher forward loss increases conduction heating; lower surge rating limits transient robustness	Select only for cost-sensitive, low-surge environments where thermal margin exceeds 15 °C

Compared with STTH3L06S and ES3J, S3JB-13 offers optimal balance of low V_F, high I_FSM, and SMB thermal performance-enabling smaller heatsinking and better surge resilience in space-constrained AC/DC converters.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The S3JB-13 has a specified operating junction temperature range of –65 °C to +150 °C. For continuous 3.0 A operation, thermal design must ensure junction temperature remains ≤150 °C using the 10 °C/W R_JT value and measured terminal temperature, per Figure 1 derating curve. Exceeding this limit risks parametric drift and premature failure.

Can S3JB-13 be used in full-wave bridge configurations?

Yes-S3JB-13 is a single diode intended for use in discrete full-wave bridge assemblies. Four units can form a bridge rectifier; its 600 V V_RRM supports 400 VAC input (264 VAC × √2 ≈ 373 V), providing sufficient margin for line surges and ripple peaks in standard bridge topologies.

Is the SMB package lead-free and RoHS compliant?

Yes-the S3JB-13 uses matte tin plating and complies with RoHS Directive 2011/65/EU (Revision 13.2.2003), including exemptions for glass and high-temperature solder. It meets J-STD-020C Level 1 moisture sensitivity and is qualified for standard Pb-free reflow profiles per Diodes' AP02007 packaging specification.

How does capacitive loading affect the S3JB-13 current rating?

Per datasheet Note: "For capacitive load, derate current by 20%." At full-rated 3.0 A, this means limiting average output current to 2.4 A when feeding a bulk capacitor input filter-due to increased peak current stress and reduced conduction angle, which elevates junction temperature beyond the resistive/inductive load derating curve.
