Diodes Incorporated S1JB-13-F

Overview

S1JB-13-F from Diodes Incorporated is a 1.0A, 600V peak repetitive reverse voltage (VRRM), glass passivated surface-mount silicon rectifier diode in the SMB package. It delivers 30A non-repetitive peak forward surge current (IFSM), exhibits ≤1.1V forward voltage (VFM) at 1.0A, and features 1.8–3.0μs reverse recovery time (trr), making it suitable for AC/DC input rectification in compact power supplies.

For engineers reviewing the S1JB-13-F datasheet, S1JB-13-F pinout, S1JB-13-F application, or S1JB-13-F equivalent, key selection criteria include its 600V blocking capability, SMB thermal performance (RθJT = 30°C/W), 1.0A average forward current rating at 100°C terminal temperature, and RoHS-compliant lead-free matte tin plating.

Technical Context

This SMB-packaged rectifier operates as a single-phase, half-wave silicon junction diode optimized for general-purpose AC line rectification and DC power conversion. Its glass passivated die construction ensures high reliability under surge stress, while the 30A IFSM rating supports transient overload conditions typical in offline switch-mode power supply (SMPS) front-ends.

The device's 10pF typical junction capacitance (CT) at 1MHz/4V and ≤100μA peak reverse leakage at 125°C enable stable operation in high-frequency rectifier circuits with minimal capacitive coupling and low standby loss.

FAQ

What is the maximum allowable junction temperature for S1JB-13-F?

The absolute maximum junction temperature is +150°C, but sustained operation above this value risks permanent degradation. The device is rated for 1.0A average forward current only when the terminal temperature (TT) is held at +100°C-requiring appropriate PCB copper area to achieve RθJT = 30°C/W and limit junction rise.

Can S1JB-13-F replace S1J-13-F in existing designs?

Yes-S1JB-13-F is the SMB-package variant of the S1J-13-F (SMA package), sharing identical electrical specifications (600V VRRM, 1.0A IO, 30A IFSM). The change affects only mechanical fit: SMB has larger body dimensions (3.30–3.94mm × 4.06–4.57mm) and higher thermal mass, requiring updated stencil and footprint.

Is S1JB-13-F suitable for use in a full-bridge rectifier configuration?

Yes-each S1JB-13-F diode can serve as one leg of a full-bridge rectifier. Four units are required per bridge. Ensure all four devices are from the same reel/batch to minimize VFM mismatch, and verify that PCB layout provides symmetrical thermal paths to maintain balanced current sharing under load.

Does S1JB-13-F require derating when used with capacitive loads?

Yes-the datasheet specifies a 20% derating of average forward current (IO) for capacitive-input filter configurations. At 25°C ambient, the 1.0A rating becomes 0.8A to prevent excessive peak current stress during capacitor charging, which could otherwise accelerate wear-out or trigger thermal runaway.
