Product details

Overview

S5BC 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 front-end rectification for industrial power supplies and LED drivers.

For engineers reviewing the S5BC datasheet, S5BC pinout, S5BC application, or S5BC equivalent, key selection criteria include VRRM rating, thermal resistance (10°C/W), surge robustness (100A @ 8.3ms), and RoHS-compliant lead-free plating for automated assembly compatibility.

Technical Context

This device operates as a single-phase, half-wave silicon rectifier with glass-passivated junction for enhanced reliability under transient stress. Its 10°C/W junction-to-terminal thermal resistance enables sustained 5.0A conduction at +75°C terminal temperature when mounted on 5.0mm² copper pads.

Electrical behavior includes low capacitance (40pF at 1MHz/4V), minimal leakage (10µA @ 25°C, 250µA @ 125°C), and defined derating curves for forward current and surge capability across temperature and cycle count - critical for high-efficiency offline power conversion designs.

Key Specifications

Parameter	Value and Actual Design Meaning
VRRM	100 V - Maximum repetitive reverse voltage before breakdown; defines safe AC input voltage headroom in bridge or single-diode rectifier stages.
IO @ TT=75°C	5.0 A - Continuous DC output current capability with thermal management; sets minimum heatsinking requirement for 230VAC input supplies.
VFM @ IF=5.0A	1.15 V - Forward voltage drop determining conduction loss (5.75W at full load); directly impacts efficiency and thermal design.
IFSM @ 8.3ms	100 A - Surge withstand for inrush and line transients; supports robust startup in switched-mode power supplies.
RθJT	10 °C/W - Junction-to-terminal thermal resistance; enables direct PCB copper pad thermal path design without additional heatsink.
IRM @ 125°C	250 µA - Reverse leakage at elevated temperature; affects standby power and isolation integrity in high-temperature environments.

Pinout & Package

Package: SMC (DO-214AB), molded plastic case with UL 94V-0 flammability rating, matte tin-plated terminals, cathode band polarity marking, and 0.21g mass.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Input current entry point during forward conduction	Connected to AC source or transformer secondary; must handle full 5A RMS and 100A surge currents.
Cathode	Output current exit point during forward conduction	Feeds bulk capacitor or downstream converter; polarity marked by band; requires low-inductance layout for EMI control.

Key Features

Feature	Design Value
Glass passivated die construction	Prevents moisture ingress and surface contamination, enabling stable long-term operation in humid industrial environments.
Surge rating: 100A @ 8.3ms	Withstands cold-start inrush and lightning-induced line surges without degradation - eliminates need for external MOV coordination in Class II designs.
Lead-free, halogen-free "Green" finish	Complies with RoHS 2 and JEDEC J-STD-020 Level 1 moisture sensitivity - supports lead-free reflow and eliminates post-solder cleaning.
Low thermal resistance (10°C/W)	Allows direct PCB copper pad heat sinking; reduces system footprint vs. TO-220 alternatives requiring mechanical heatsinks.

Applications

Industrial AC/DC Power Supplies

LED Driver Input Rectification

Use Scenario: Off-line 85–265VAC input stage in DIN-rail power supplies delivering 24V/5A output.

IC Role / Device Role / Timing Role: Primary rectifier converting AC to pulsating DC prior to bulk capacitor and PWM controller.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor MUR5100CT	TO-220AC package, dual common-cathode configuration, 100V VRRM, 5A IO, but higher VFM (1.7V typical) and no glass passivation.	Requires heatsink mounting and manual soldering; unsuitable for high-density SMT production.	Select when dual-diode topology or through-hole assembly is required; avoid for space-constrained or automated lines.
Vishay VS-50WQ10	Surface-mount SMC package, Schottky architecture, 100V VRRM, 5A IO, lower VFM (0.72V), but higher IRM (1mA @ 125°C) and no surge rating specification.	Better efficiency at light loads, but insufficient surge immunity for mains-connected applications.	Select only for low-voltage, low-surge environments like DC-DC input stages; not recommended for AC line rectification.

Compared with MUR5100CT and VS-50WQ10, S5BC uniquely balances SMT manufacturability, 100A surge robustness, and glass-passivated reliability - making it optimal for cost-sensitive, high-volume AC/DC rectification where thermal and transient performance are jointly critical.

FAQ

What is the maximum allowable junction temperature for S5BC?

The S5BC has an operating junction temperature range of –65°C to +150°C per datasheet DS16007 Rev. 10–2. Its thermal design must ensure TJ does not exceed +150°C under worst-case conditions, using the 10°C/W RθJT value and measured terminal temperature as proxy.

Can S5BC be used in full-wave bridge configurations?

Yes - S5BC is a single diode in SMC package and is commonly used in discrete full-wave bridge designs (e.g., four S5BC devices). It is not a monolithic bridge; each unit functions as one leg, requiring external interconnection per standard bridge topology.

Is S5BC suitable for use with capacitive input filters?

No - the datasheet explicitly states that for capacitive loads, the average forward current must be derated by 20%. At 5.0A rated IO, this limits continuous operation to 4.0A when feeding bulk capacitors without inductive filtering, due to increased peak current stress.

Does S5BC meet automotive qualification standards?

No - S5BC is not AEC-Q101 qualified. While it operates from –65°C to +150°C and handles 100A surges, it lacks automotive-specific testing (e.g., HTOL, temperature cycling, ESD), making it appropriate for industrial and commercial applications but not automotive ECUs or powertrain systems.
