Product details

Overview

S5AC-13-F from Diodes Incorporated is a 5.0A, 50V glass passivated surface-mount rectifier diode in SMC package, optimized for high-current AC/DC conversion with low 1.15V forward voltage at 5.0A and 100A surge capability; used in offline power supplies, DC adapters, and industrial SMPS input stages.

For engineers reviewing the S5AC-13-F datasheet, S5AC-13-F pinout, S5AC-13-F application, or S5AC-13-F equivalent, key selection criteria include peak repetitive reverse voltage (50V), average forward current (5.0A @ T_T = +75°C), thermal resistance (10°C/W), surge rating (100A @ 8.3ms), and RoHS-compliant lead-free plating.

Technical Context

This device operates as a single-phase, half-wave silicon rectifier with glass-passivated junction for enhanced reliability under thermal cycling and humidity exposure. Its 50V V_RRM and 5.0A I_O rating target medium-voltage, medium-current front-end rectification where low conduction loss and robust surge immunity are required.

The SMC package enables automated placement and provides 10°C/W junction-to-terminal thermal resistance when mounted on 5.0mm² copper pads. Reverse leakage remains ≤10µA at 25°C and ≤250µA at 125°C, supporting stable operation across extended temperature ranges (-65°C to +150°C).

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	50 V - Maximum repetitive reverse voltage before breakdown; defines safe operating limit in AC line rectification.
I_O	5.0 A @ T_T = +75°C - Continuous average forward current capacity with standard PCB heatsinking.
V_FM	1.15 V @ I_F = 5.0A - Forward voltage drop directly impacts conduction loss and thermal design in power stages.
I_FSM	100 A @ 8.3ms - Peak non-repetitive surge current handling for inrush and transient overload protection.
R_θJT	10 °C/W - Junction-to-terminal thermal resistance determines temperature rise per watt dissipated under PCB heatsink conditions.
I_RM	≤10 µA @ 25°C - Low reverse leakage ensures minimal standby power loss and stable blocking in high-impedance circuits.
T_J/T_STG	-65°C to +150°C - Wide operating and storage temperature range supports industrial and automotive under-hood environments.

Pinout & Package

Package: SMC (Surface Mount Case), molded plastic body with UL 94V-0 flammability rating, cathode identified by band or notch, matte tin-plated terminals solderable per MIL-STD-202 Method 208.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Current entry point during forward conduction	Connected to AC input or transformer secondary; must handle full load current and surge transients.
Cathode	Current exit point during forward conduction	Connected to bulk capacitor or downstream converter; polarity marking (band/notch) prevents reverse installation.

Key Features

Feature	Design Value
Glass passivated die construction	Improves moisture resistance and long-term reliability in humid or thermally cycled environments.
100A peak surge rating (8.3ms)	Withstands cold-start inrush and lightning-induced line surges without degradation in AC/DC front ends.
Lead-free, halogen- and antimony-free "Green" finish	Meets RoHS 2 (2011/65/EU) and environmental compliance requirements for global electronics manufacturing.
Low 1.15V forward voltage at 5.0A	Reduces conduction loss by ~15% vs. comparable 1N54xx series, lowering thermal stress in compact layouts.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor MUR550E	Ultrafast recovery (75ns), higher V_F (1.7V @ 5A), same SMC package and 50V rating.	Better for high-frequency switching (e.g., PFC boost stages); less optimal for pure 60Hz rectification due to higher conduction loss.	Select when EMI reduction or reduced reverse recovery ringing is critical; avoid if minimizing heat in low-frequency designs is priority.
Vishay VS-50WQ04FNTR-M3	Schottky architecture, 40V V_R, lower V_F (0.52V @ 5A), but limited to ≤125°C operation.	Superior efficiency below 40V systems (e.g., 24V AC input); unsuitable for 50V-rated mains-connected designs requiring margin.	Choose only for sub-40V AC inputs where thermal headroom is constrained; verify derating for ambient >85°C.

Compared with MUR550E and VS-50WQ04FNTR-M3, S5AC-13-F delivers optimal balance of low conduction loss, robust 50V margin, and wide-temperature reliability for general-purpose 50/60Hz rectification-without ultrafast or Schottky trade-offs in cost, leakage, or voltage rating.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The S5AC-13-F has an absolute maximum junction temperature of +150°C. For reliable long-term operation, junction temperature should be maintained ≤125°C under steady-state conditions using appropriate PCB copper area (5.0mm² minimum per terminal) and ambient derating per Figure 1 in DS16007 Rev. 10-2.

Can S5AC-13-F replace a 1N5408 in existing designs?

Yes, S5AC-13-F is a direct SMC-package replacement for through-hole 1N5408 (50V/3A) with higher current rating (5.0A vs. 3.0A) and superior surge capability (100A vs. 60A). Layout must accommodate SMC footprint and reflow profile; no circuit modification is needed for basic rectification.

Is the cathode polarity marked on the device body?

Yes, the cathode is clearly marked with a contrasting band or notch on the top surface of the SMC package, aligned with the cathode terminal. This marking is visible after placement and matches industry-standard polarity identification for surface-mount rectifiers.

Does S5AC-13-F require derating for capacitive loads?

Yes-per DS16007, average forward current must be derated by 20% when used with capacitive-input filter configurations (e.g., bulk capacitor directly after rectifier). At +75°C terminal temperature, rated I_O drops from 5.0A to 4.0A under such conditions to prevent thermal runaway.
