Diodes Incorporated 1N5393-T

Overview

1N5393-T from Diodes Incorporated is a 200 V, 1.5 A general-purpose silicon rectifier diode in DO-15 package, featuring 1.1 V forward voltage at 1.5 A, 50 A non-repetitive surge rating, and 5.0 µA reverse leakage at 25°C, used in AC/DC power supplies and input rectification stages of industrial power adapters.

For engineers reviewing the 1N5393-T datasheet, 1N5393-T pinout, 1N5393-T application, or 1N5393-T equivalent, key selection criteria include peak repetitive reverse voltage (200 V), average rectified current (1.5 A @ 70°C), thermal resistance (55 °C/W), and DO-15 mechanical compatibility with through-hole PCB layouts.

Technical Context

This axial-lead rectifier operates in single-phase, half-wave configurations with resistive or inductive loads at 60 Hz; capacitive loads require 20% current derating. It uses planar passivated junction technology for stable reverse characteristics and low leakage across its -65°C to +150°C operating range.

Thermal performance is defined by junction-to-ambient resistance of 55 °C/W (with leads held at ambient at 9.5 mm from case) and junction-to-lead resistance of 25 °C/W, enabling reliable operation in compact, convection-cooled power supply designs without forced airflow.

FAQ

What is the maximum operating temperature for the 1N5393-T?

The 1N5393-T has an operating and storage temperature range of -65°C to +150°C. Its junction-to-ambient thermal resistance is 55 °C/W, so at 1.5 A forward current and 1.1 V drop, power dissipation is ~1.65 W-resulting in a junction temperature rise of ~91°C above ambient, staying within safe limits at ≤59°C ambient.

Is the 1N5393-T RoHS compliant?

Yes, the 1N5393-T features a lead-free finish and is RoHS compliant per EU Directive 2002/95/EC (RoHS revision 13.2.2003), with exemptions applied for glass and high-temperature solder per Annex Notes 5 and 7. Tin-plated terminals meet MIL-STD-202 Method 208 solderability requirements.

Can the 1N5393-T replace the 1N4004 in existing designs?

No-the 1N5393-T has a 200 V VRRM, while the 1N4004 specifies 400 V. Substituting it into a design originally using 1N4004 risks reverse breakdown under 230 VAC peak conditions (≈325 V). Use only where system-level analysis confirms 200 V reverse margin is sufficient, such as 120 VAC-only or derated applications.

What does the "-T" suffix indicate in 1N5393-T?

The "-T" suffix denotes tape-and-reel packaging: 4,000 pieces per reel on 13-inch diameter reels, optimized for automated SMT placement equipment. This differs from "-B" (bulk) and "-S" (DO-41 package), and ensures consistent feed reliability and ESD-safe handling in high-speed assembly lines.
