Diodes Incorporated S5BC-13

Overview

S5BC-13 from Diodes Incorporated is a 100V peak repetitive reverse voltage, 5.0A average forward current glass passivated surface-mount rectifier in SMC package, featuring 1.15V max forward voltage at 5.0A and 100A non-repetitive surge capability; used in AC/DC input stage rectification for industrial power supplies.

For engineers reviewing the S5BC-13 datasheet, S5BC-13 pinout, S5BC-13 application, or S5BC-13 equivalent, key selection criteria include VRRM rating, IF(AV) derating at elevated terminal temperature, IFSM surge margin, thermal resistance (RθJT = 10°C/W), and RoHS-compliant matte tin plating for automated assembly.

Technical Context

This device operates as a single-phase, half-wave silicon rectifier with glass-passivated junction for enhanced reliability under transient overvoltage stress. Its 100V VRRM rating targets universal-input offline AC/DC front-end designs where moderate blocking voltage and high surge tolerance are required.

The SMC package enables high-power dissipation with low thermal resistance (10°C/W junction-to-terminal) when mounted on 5.0mm² copper pads. Electrical behavior follows standard PN-junction rectifier characteristics: forward conduction governed by VFM = 1.15V @ 5.0A, reverse leakage limited to 10µA @ 25°C and 250µA @ 125°C.

FAQ

What is the maximum allowable junction temperature for S5BC-13?

The absolute maximum junction temperature is +150°C, consistent with its specified operating temperature range (TJ, TSTG = –65°C to +150°C). Derating begins at +75°C terminal temperature per Figure 1; actual TJ depends on RθJT (10°C/W), IF, and thermal interface to PCB copper.

Can S5BC-13 replace S5AC-13 in an existing design?

Yes, with electrical verification: S5BC-13 has VRRM = 100V vs. S5AC-13's 50V, so it provides higher reverse voltage margin. All other parameters (IF(AV), VFM, IFSM, package) are identical. No layout or thermal changes are needed if the original design already meets 100V requirements.

Is S5BC-13 suitable for use in a full-wave bridge configuration?

Yes - each S5BC-13 functions as a single rectifier element. Four units can be assembled into a discrete full-wave bridge. Its SMC package and 100A surge rating make it appropriate for medium-power bridges where integrated bridges lack sufficient surge margin or thermal performance.

Does S5BC-13 require snubber circuitry in typical 60Hz rectifier applications?

No snubber is required for standard resistive or inductive loads at 60Hz. The device's soft reverse recovery and low CT (40pF) minimize switching noise. Snubbers may be added only if parasitic ringing occurs due to long traces or high di/dt in capacitor-input filters with large bulk capacitors.
