Diodes Incorporated S3BB-13-F

Overview

S3BB-13-F from Diodes Incorporated is a 100 V peak repetitive reverse voltage, 3.0 A average rectified surface-mount glass passivated diode in SMB package, featuring 1.15 V forward voltage at 3.0 A and 100 A non-repetitive surge capability - used in AC/DC input stage rectification for industrial power supplies.

For engineers reviewing the S3BB-13-F datasheet, S3BB-13-F pinout, S3BB-13-F application, or S3BB-13-F equivalent, key selection criteria include V_RRM = 100 V, I_O = 3.0 A @ T_T = +75°C, I_FSM = 100 A (8.3 ms), V_F = 1.15 V @ 3.0 A, and SMB package thermal resistance R_θJT = 10 °C/W.

Technical Context

This device operates as a single-phase, half-wave silicon rectifier with glass-passivated junction for enhanced reliability under transient stress. Its 100 V V_RRM rating supports universal-input offline rectification up to 120 VAC RMS, while the 100 A surge rating enables robust handling of inrush currents in unregulated power stages.

The SMB package provides defined thermal path to PCB copper (R_θJT = 10 °C/W on 5.0 mm² pad), and its cathode band polarity marking ensures unambiguous orientation during automated placement. Reverse leakage remains ≤10 µA at 25°C and ≤250 µA at 125°C under rated blocking voltage.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar general-purpose rectifier applications.

Compared with STPS3L100SB and MUR310, S3BB-13-F offers lowest cost, tightest leakage, and smallest footprint for 50–100 kHz offline rectification - but lacks Schottky efficiency or ultrafast recovery for high-frequency designs.

Availability

S3BB-13-F is available at Aetrix Electronics and suitable for industrial AC/DC power supplies, LED driver input stages, consumer adapter input rectification, and DC motor control flyback clamping requiring stable component supply and RoHS-compliant sourcing.

Supply support for S3BB-13-F includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, headquartered in Dallas, Texas, with design centers across Asia and manufacturing in China, Malaysia, and Taiwan.

S3BB-13-F belongs to the S3x/B series of glass-passivated surface-mount rectifiers engineered for cost-sensitive, high-volume AC/DC front-end applications where reliability, surge tolerance, and regulatory compliance are prioritized over ultrafast switching or Schottky efficiency.

FAQ

What is the maximum operating temperature for S3BB-13-F?

The S3BB-13-F has an operating and storage temperature range of –65°C to +150°C. Its average rectified current rating of 3.0 A is specified at terminal temperature T_T = +75°C, and derating begins above that point per Figure 1 in DS16005. Junction-to-terminal thermal resistance is 10°C/W with a 5.0 mm² copper pad.

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

Yes - S3BB-13-F features matte tin lead-free plating, complies with J-STD-020 Level 1 moisture sensitivity, and is qualified for standard Pb-free reflow profiles (peak 260°C). Its UL 94V-0 mold compound withstands multiple reflow cycles without delamination or warpage.

How does S3BB-13-F differ from S3AB-13-F?

S3BB-13-F has V_RRM = 100 V and V_F = 1.15 V @ 3.0 A; S3AB-13-F shares the same SMB package and current rating but has V_RRM = 50 V and slightly lower V_F (1.10 V). The 'B' suffix denotes 100 V rating; 'A' denotes 50 V. Both share identical thermal and surge specifications.

Can S3BB-13-F replace a 1N4007 in existing designs?

No - S3BB-13-F is an SMB surface-mount device rated for 100 V and 3.0 A, whereas 1N4007 is through-hole, rated 1000 V and 1.0 A. While V_RRM matches the lower end of 1N4007's range, the package, current rating, and mounting method are incompatible without PCB redesign and thermal validation.
