Product details

Overview

S3JB from Taiwan Semiconductor is a 3A, 600V repetitive peak reverse voltage (V_RRM) standard surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring 1.15V max forward voltage at 3A/25°C, 80A surge capability, and 150°C max junction temperature - used in AC/DC front-end rectification for industrial SMPS and lighting ballasts.

For engineers reviewing the S3JB datasheet, S3JB pinout, S3JB application, or S3JB equivalent, key selection criteria include verified V_RRM = 600V, I_F = 3A continuous rating, trr = 1500ns recovery time, moisture sensitivity level 1 compliance, and SMB package thermal resistance R_θJL = 10°C/W.

Technical Context

The S3JB is a single-die, glass-passivated PN-junction standard rectifier optimized for high-reliability, medium-voltage switching power conversion. It operates with a maximum reverse recovery time of 1500ns under IF = 0.5A / IR = 1.0A / Irr = 0.25A conditions and exhibits 10µA max reverse leakage at 25°C and rated VR.

Its thermal design supports sustained 3A conduction with junction-to-lead resistance of 10°C/W, enabling direct PCB copper pad heat sinking without auxiliary heatsinks in typical 25–70°C ambient environments. The device meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - Maximum non-repetitive reverse blocking voltage; defines usable input voltage range in bridge or single-phase rectifier stages
I_F	3 A - Continuous average forward current; sets minimum trace width and copper area for thermal management
I_FSM	80 A - Peak surge current (8.3ms half-sine); determines robustness against line transients and cold-start inrush
V_F	≤1.15 V @ 3A, 25°C - Forward drop directly impacts conduction loss and efficiency in 50–100W SMPS designs
t_rr	1500 ns - Reverse recovery time affects EMI generation and snubber sizing in hard-switched topologies
R_θJL	10 °C/W - Junction-to-lead thermal resistance enables direct thermal path to PCB copper, simplifying thermal layout

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH3L06S	V_RRM = 600V, I_F = 3A, t_rr = 75ns (ultrafast), VF ≈ 1.3V @ 3A	Better suited for high-frequency (>100kHz) PFC or resonant converters requiring faster recovery	Select STTH3L06S only if t_rr < 100ns is required; S3JB offers lower V_F and higher surge tolerance
SB360-E3/5BT	V_RRM = 60V (not 600V), I_F = 3A, VF ≈ 0.52V @ 3A, SMB package	Limited to low-voltage DC-DC inputs; incompatible for AC line rectification	SB360-E3/5BT is not a voltage-compatible alternative; use only in ≤60V systems where low V_F dominates efficiency

Compared with STTH3L06S, the S3JB trades ultrafast recovery for lower forward loss and higher surge robustness - making it preferable in cost-sensitive, medium-frequency SMPS. Unlike SB360-E3/5BT, the S3JB's 600V rating enables direct use after 230VAC bridge rectification without series stacking.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for the S3JB?

The S3JB has a maximum repetitive peak reverse voltage (V_RRM) of 600 V, as confirmed in the Absolute Maximum Ratings table on page 1 of the official Taiwan Semiconductor datasheet (Version M2102). This rating allows the S3JB to safely block reverse voltage in single-phase rectifier circuits fed from 230VAC mains after bridge rectification, providing sufficient margin above the 325V peak.

Does the S3JB have a specified reverse recovery time (t_rr)?

Yes, the S3JB has a reverse recovery time (t_rr) of 1500 ns, measured under conditions of IF = 0.5A, IR = 1.0A, and Irr = 0.25A, per the Electrical Specifications table on page 2 of the Taiwan Semiconductor datasheet. This value is typical for standard (non-ultrafast) rectifiers and informs snubber design and EMI filtering in 50–100kHz SMPS applications.

Is the S3JB RoHS and halogen-free compliant?

Yes, the S3JB is RoHS compliant and halogen-free in accordance with IEC 61249-2-21, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the molding compound satisfies UL 94V-0 flammability standards.

What is the thermal resistance from junction to lead (R_θJL) for the S3JB?

The junction-to-lead thermal resistance (R_θJL) for the S3JB is 10°C/W, as published in the Thermal Performance table on page 2 of the official datasheet. This parameter enables accurate estimation of junction temperature rise above the PCB copper pad temperature and confirms suitability for conduction-cooled layouts without external heatsinks in most 3A applications.

What does the marking code 'S3JB' indicate on the device body?

The marking code 'S3JB' on the S3JB device body corresponds directly to the orderable part number and identifies it as the 600V variant within the S3AB–S3MB family, per the Absolute Maximum Ratings table on page 1. The 'J' denotes 600V V_RRM, and the 'B' suffix indicates standard rectifier configuration (single die, DO-214AA package).
