Diodes Incorporated S3D-13-F

Overview

S3D-13-F from Diodes Incorporated is a 200 V PIV, 3.0 A average forward current glass passivated surface-mount rectifier in SMB package, featuring 1.15 V forward voltage at 3.0 A, 100 A non-repetitive surge capability, and RoHS-compliant matte tin plating-used in AC/DC front-end rectification for industrial power supplies and LED drivers.

For engineers reviewing the S3D-13-F datasheet, S3D-13-F pinout, S3D-13-F application, or S3D-13-F equivalent, key selection criteria include peak repetitive reverse voltage (200 V), thermal resistance (10 °C/W), junction temperature range (–65 to +150 °C), and SMB package compatibility with automated SMT assembly.

Technical Context

This device operates as a single-phase, half-wave silicon rectifier optimized for resistive or inductive loads at 60 Hz. Its glass passivated die construction ensures stable reverse leakage (<10 µA at 25 °C, <250 µA at 125 °C) and robust surge immunity up to 100 A (8.3 ms half-sine).

The SMB package provides 10 °C/W junction-to-terminal thermal resistance when mounted on a 5.0 mm² copper pad, enabling reliable 3.0 A continuous conduction at terminal temperature ≤75 °C per derating curve.

FAQ

What is the maximum allowable junction temperature for S3D-13-F?

The absolute maximum junction temperature is +150 °C, with continuous operation limited to terminal temperature ≤75 °C per the forward current derating curve. Operation above this requires active thermal management or reduced load current to maintain junction temperature within specification.

Can S3D-13-F replace S3D-13 in existing designs?

Yes-S3D-13-F is the RoHS-compliant, lead-free version of S3D-13, sharing identical electrical specs, SMB package dimensions, and thermal performance. The "-F" suffix denotes matte tin finish; no layout or thermal redesign is needed for drop-in replacement.

Is S3D-13-F suitable for capacitance-input filter applications?

No-it is rated for resistive or inductive loads only. For capacitance-input filters, Diodes Incorporated specifies a 20% current derating; use instead the S3D-13-F's higher-surge variants like S3DHR-13-F if capacitor charging currents exceed 2.4 A RMS.

How is polarity identified on the S3D-13-F SMB package?

Polarity is marked by a visible cathode band at one end of the SMB body. The banded end is the cathode (DC output); the opposite end is the anode (AC input). This matches industry-standard SMB diode orientation and aligns with PCB silkscreen indicators.
