Diodes Incorporated S3BB-13

Overview

S3BB-13 from Diodes Incorporated is a 100 V peak repetitive reverse voltage, 3.0 A average rectified output current, glass passivated surface-mount silicon rectifier in SMB package. It delivers low forward voltage drop (1.15 V @ 3.0 A), handles 100 A non-repetitive surge current, and operates from –65 °C to +150 °C - used in AC/DC front-end rectification for industrial power supplies and LED drivers.

For engineers reviewing the S3BB-13 datasheet, S3BB-13 pinout, S3BB-13 application, or S3BB-13 equivalent, key selection criteria include its 100 V VRRM rating, 10 °C/W junction-to-terminal thermal resistance, 40 pF typical junction capacitance, and RoHS-compliant lead-free plating - all critical for thermal management and EMI-sensitive 60 Hz rectifier designs.

Technical Context

This device is a single-phase, half-wave silicon rectifier diode with glass passivated die construction, optimized for automated SMT assembly. Its low V_F and high I_FSM support reliable operation under transient overload conditions in line-powered systems.

The SMB package provides defined thermal path to PCB copper (R_JT = 10 °C/W on 5.0 mm² pad), and its cathode band polarity marking ensures unambiguous orientation during placement. Rated for resistive/inductive loads at 60 Hz, it requires 20% current derating for capacitive loads.

FAQ

What is the maximum allowable junction temperature for S3BB-13?

The absolute maximum junction temperature is +150 °C, and the device is rated for continuous operation across –65 °C to +150 °C storage and operating range. Derating begins above 75 °C case temperature per Figure 1 in DS16005 Rev. 10–2, where I_O drops linearly to zero at 150 °C.

Is S3BB-13 compatible with lead-free reflow processes?

Yes - S3BB-13 features matte tin lead-free plating and is qualified for standard Pb-free reflow profiles per J-STD-020C. Its SMB package withstands peak temperatures up to 260 °C for 10 seconds, matching IPC/JEDEC specifications for Class 3 assemblies.

Can S3BB-13 be used in full-wave bridge configurations?

No - S3BB-13 is a single anode-cathode rectifier diode. Full-wave bridge operation requires four discrete diodes or a monolithic bridge rectifier (e.g., GBU4K). Using two S3BB-13 devices in a center-tapped configuration is possible but not recommended due to mismatched V_F and thermal coupling limitations.

How does capacitive load affect S3BB-13 current rating?

For capacitive-input filter loads, the average output current rating must be reduced by 20% - i.e., from 3.0 A to 2.4 A - to prevent excessive peak forward current and ensure reliability. This derating accounts for high crest-factor currents drawn during capacitor recharge cycles.
