Diodes Incorporated 1N5392-T

Overview

1N5392-T from Diodes Incorporated is a 100 V peak repetitive reverse voltage, 1.5 A average rectifier diode in DO-15 package with 1.1 V forward voltage drop at 1.5 A and 50 μA reverse leakage at 100 °C, used in AC/DC input stage rectification for offline power supplies.

For engineers reviewing the 1N5392-T datasheet, 1N5392-T pinout, 1N5392-T application, or 1N5392-T equivalent, key selection criteria include VRRM rating, IF(AV) derating curve, surge capability (50 A), thermal resistance (RθJA = 55 °C/W), and DO-15 mechanical compatibility with PCB layout constraints.

Technical Context

This general-purpose silicon rectifier operates in single-phase, half-wave configurations with resistive or inductive loads at 60 Hz. It is not rated for capacitive loads without 20% current derating.

Its junction-to-ambient thermal resistance of 55 °C/W and junction-to-lead resistance of 25 °C/W define thermal management requirements; maximum operating temperature is +150 °C with storage down to –65 °C.

Key Specifications

Pinout & Package

FAQ

Is the 1N5392-T RoHS compliant?

Yes. The 1N5392-T features a lead-free finish and complies with RoHS Directive 2002/95/EC, including applicable exemptions for glass and high-temperature solder per EU Annex Notes 5 and 7. Tin-plated leads meet MIL-STD-202 solderability requirements.

What is the maximum ambient temperature for full 1.5 A current rating?

The 1.5 A average forward current rating applies only at TA = 70 °C. Above this temperature, current must be linearly derated per Figure 1 in the datasheet, reaching zero at 150 °C ambient. At 100 °C ambient, the usable current is approximately 1.0 A.

Can the 1N5392-T be used in capacitive-load circuits?

No. The datasheet explicitly requires 20% derating of IF(AV) for capacitive loads due to high inrush current. For such applications, use a higher-current-rated diode or add inrush limiting (e.g., NTC thermistor) to stay within the 50 A IFSM limit and prevent premature failure.

How does the DO-15 package differ from DO-41 for the 1N5392?

The DO-15 package has larger dimensions (B = 5.50–7.62 mm vs. DO-41's 4.06–5.21 mm) and higher weight (0.40 g vs. 0.30 g), providing better thermal mass and mechanical robustness. Its longer leads improve solder joint reliability in vibration-prone environments like industrial controls.
