Product details

Overview

1N5399G-T from Diodes Incorporated is a 1.5A, 1000V glass passivated general-purpose rectifier diode in DO-15 package, featuring 1.1V forward voltage at 1.5A, 50A non-repetitive surge capability, and 5µA reverse leakage at 25°C - used in AC/DC power supplies, input rectification stages, and offline SMPS front-end bridges.

For engineers reviewing the 1N5399G-T datasheet, 1N5399G-T pinout, 1N5399G-T application, or 1N5399G-T equivalent, key selection criteria include peak reverse voltage rating (1000V), thermal resistance (80°C/W), derated current vs. ambient temperature, and DO-15 mechanical compatibility with legacy through-hole PCB layouts.

Technical Context

This device operates as a single-phase, half-wave silicon rectifier optimized for 60Hz line-frequency applications. Its glass passivation ensures stable junction performance under humidity and thermal cycling, while the DO-15 case provides standardized lead spacing (25.4mm) and UL 94V-0 flammability compliance.

The 1N5399G-T exhibits defined derating behavior: average forward current drops from 1.5A at 55°C ambient to zero at ~175°C case temperature, and reverse leakage rises to 200µA at 100°C - critical for high-temperature industrial power supply designs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	1000 V - Maximum repetitive reverse voltage before breakdown; defines safe operation in 800V AC mains-derived circuits.
I_O	1.5 A @ T_A = 55°C - Continuous DC output current with leads held at ambient at 9.5mm from case; requires heatsinking above 55°C.
V_FM	1.1 V @ I_F = 1.5A - Forward conduction loss directly impacts efficiency and thermal rise in rectifier stage.
I_FSM	50 A @ 8.3ms - Surge withstand for cold-start inrush or lightning-induced transients on AC input lines.
R_θJA	80 °C/W - Junction-to-ambient thermal resistance; determines temperature rise under load without heatsink.
I_RM	5 µA @ 25°C / 200 µA @ 100°C - Reverse leakage affects standby power and high-impedance bias networks.

Pinout & Package

Package: DO-15 molded plastic case (UL 94V-0), 25.4mm lead spacing, cathode band marking, tin-plated leads solderable per MIL-STD-202 Method 208.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Positive input terminal during forward conduction	Connected to AC source or transformer secondary; must handle full surge current and thermal stress.
Cathode	DC output terminal during forward conduction	Connected to filter capacitor or downstream regulator; polarity marked by band on DO-15 body.

Key Features

Feature	Design Value
Glass passivated die	Enhances moisture resistance and long-term reliability in humid environments without hermetic sealing.
50A surge rating	Supports robust inrush current handling in unregulated linear power supplies and transformer-coupled inputs.
Low 1.1V V_F	Reduces conduction loss and self-heating compared to higher-V_F rectifiers like 1N4007 (1.1V typical but higher variance).
DO-15 mechanical standard	Ensures drop-in replacement compatibility with existing through-hole footprints and wave-solder processes.

Applications

AC/DC Power Supply Input Stage

Offline Switch-Mode Power Supply (SMPS) Front-End

Use Scenario: Rectifying 230VAC mains input prior to bulk capacitor filtering in open-frame power supplies.

IC Role / Device Role / Timing Role: General-purpose rectifier diode performing half-wave or full-wave bridge function.

Use Value: 1000V V_RRM provides 2× safety margin over 230VAC peak (≈325V), minimizing risk of reverse breakdown during line surges.

Use Scenario: Input rectification in low-cost flyback converters where cost and footprint are prioritized over ultra-low leakage.

IC Role / Device Role / Timing Role: Discrete rectifier in discrete bridge configuration feeding primary-side energy storage.

Use Value: 1.5A I_O and 50A I_FSM support moderate-power (≤30W) designs with acceptable thermal rise using minimal copper area.

Industrial Control Power Module

Legacy Equipment Replacement

Use Scenario: Providing isolated auxiliary DC bias for PLC I/O modules operating in 0–70°C ambient environments.

IC Role / Device Role / Timing Role: Primary-side rectifier converting transformer-isolated AC to low-voltage DC rail.

Use Value: Stable 5µA reverse leakage at 25°C prevents excessive quiescent current in always-on control logic rails.

Use Scenario: Direct replacement for obsolete 1N5399 or 1N5408 in field-service repairs of aging test equipment.

IC Role / Device Role / Timing Role: Drop-in mechanical and electrical substitute in DO-15 footprint.

Use Value: RoHS-compliant tin finish and identical DO-15 dimensions enable no-change board rework without layout modification.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N5408G-T	Same 1000V V_RRM, but rated for 3A I_O; higher forward voltage (1.2V typ.) and larger DO-201AD package.	Requires PCB pad revision; better suited for higher-current designs needing margin beyond 1.5A.	Select when >1.5A continuous current or improved surge margin (100A) is required.
RS1M	1000V V_RRM, 1A I_O, faster recovery (~500ns), smaller DO-41 package, higher V_F (1.3V).	Not a drop-in replacement due to lower current rating and different lead spacing; used where switching noise matters.	Select only if fast recovery is needed and current demand ≤1A; verify thermal design with higher V_F.

Compared with 1N5408G-T and RS1M, the 1N5399G-T offers optimal balance of 1.5A rating, DO-15 compatibility, and low-cost manufacturing - making it preferred for cost-sensitive, space-constrained 20–30W AC/DC adapters where exact 1.5A capacity suffices.

FAQ

Is the 1N5399G-T RoHS compliant?

Yes, the 1N5399G-T features a lead-free finish and is RoHS compliant per EU Directive 2002/95/EC, with exemptions applied for glass and high-temperature solder per Annex Notes 5 and 7. Tin-plated leads meet MIL-STD-202 Method 208 solderability requirements.

What is the maximum operating temperature for continuous use?

The 1N5399G-T has an operating junction temperature range of –65°C to +175°C. For continuous 1.5A operation, ambient temperature must be limited to 55°C with leads held at ambient at 9.5mm from the case; derating curves show usable current falls to zero near 175°C case temperature.

Can the 1N5399G-T replace a 1N4007 in a circuit?

Yes, but only if the circuit requires ≥1000V reverse voltage rating. The 1N4007 is rated for 1000V V_RRM and 1A I_O, whereas the 1N5399G-T delivers 1.5A I_O at same V_RRM. Thermal and surge margins improve, but ensure PCB layout accommodates DO-15's 25.4mm lead spacing.

Why is this part marked "NOT RECOMMENDED FOR NEW DESIGN"?

Diodes Incorporated designates the 1N5399G-T as not recommended for new designs due to industry migration toward higher-efficiency, lower-leakage, or surface-mount alternatives (e.g., SMD rectifiers or Schottky types). It remains fully qualified and supported for legacy repair, maintenance, and cost-driven production where DO-15 through-hole assembly is retained.
