Diodes Incorporated 1N5395-T

Overview

1N5395-T from Diodes Incorporated is a 1.5A general-purpose silicon rectifier diode in DO-15 package, rated for 400V peak repetitive reverse voltage (V_RRM), 1.1V forward voltage drop at 1.5A, and 50A non-repetitive surge current. It serves as AC-to-DC input stage rectifier in offline power supplies for consumer adapters and industrial control power modules.

For engineers reviewing the 1N5395-T datasheet, 1N5395-T pinout, 1N5395-T application, or 1N5395-T equivalent, key selection criteria include V_RRM margin for line-voltage transients, thermal resistance (R_θJA = 55°C/W) under PCB-constrained airflow, and DO-15 mechanical compatibility with legacy through-hole layouts.

Technical Context

This device operates as a single-phase, half-wave rectifier under resistive or inductive loads at 60Hz. Its fast switching behavior enables high-efficiency conversion without requiring snubbers in low-frequency SMPS front-ends.

Thermal design relies on junction-to-ambient conduction via axial leads; derating begins above 70°C ambient per Fig. 1, with full 1.5A rating maintained only when leads are held at ambient temperature at 9.5mm from case.

Key Specifications

Pinout & Package

Equivalent & Alternatives

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

Compared with 1N4007-T and 1N5408-T, the 1N5395-T delivers optimal balance of 1.5A current, 400V blocking, and low 1.1V forward drop-making it ideal for cost-sensitive 12–24V power supplies where 1A is insufficient but 3A is oversized.

Availability

1N5395-T is available at Aetrix Electronics and suitable for AC-DC wall adapters, industrial control power supplies, LED driver input stages, and appliance motor control boards requiring stable component supply and legacy DO-15 footprint compatibility.

Supply support for 1N5395-T includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

FAQ

Is the 1N5395-T RoHS compliant?

Yes, the 1N5395-T features a lead-free finish and complies with RoHS Directive 2002/95/EC (as revised 13.2.2003), including exemptions for glass and high-temperature solder per EU Annex Notes 5 and 7. Tin-plated terminals meet MIL-STD-202 Method 208 solderability requirements.

What is the maximum operating temperature for continuous 1.5A operation?

The 1N5395-T sustains 1.5A average forward current only up to 70°C ambient temperature, as specified in the derating curve (Fig. 1). Above this, current must be linearly reduced to zero at 150°C junction temperature, assuming R_θJA = 55°C/W and no heatsinking.

Can the 1N5395-T replace a 1N4007 in an existing design?

Only if the design requires ≥1.5A current and operates below 400V reverse stress. The 1N5395-T offers higher current (1.5A vs. 1A) but lower V_RRM (400V vs. 1000V); substituting it into a 1N4007 circuit risks failure during line surges exceeding 400V peak.

Does the "-T" suffix indicate tape-and-reel packaging?

Yes, the "-T" suffix denotes tape-and-reel packaging: 4,000 units per reel on 13-inch diameter reels, optimized for automated SMT placement equipment-even though the DO-15 package is axial and through-hole, this format supports mixed-technology assembly lines using pick-and-place feeders with axial lead adapters.
