Product details

Overview

1N5399-T from Diodes Incorporated is a 1.5A general-purpose silicon rectifier diode with 1000V peak repetitive reverse voltage (V_RRM), 1.1V forward voltage drop at 1.5A, and 50A non-repetitive surge capability-designed for AC/DC input stage rectification in offline power supplies, LED drivers, and industrial control power circuits.

For engineers reviewing the 1N5399-T datasheet, 1N5399-T pinout, 1N5399-T application, or 1N5399-T equivalent, key selection criteria include V_RRM rating, I_O derating above 70°C, thermal resistance (R_θJA = 55°C/W), and DO-15 package 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 60Hz; capacitive loads require 20% current derating. Its fast switching behavior enables high-efficiency operation in low-frequency power conversion stages.

Thermal performance is defined by junction-to-ambient (55°C/W) and junction-to-lead (25°C/W) resistances, with rated operating temperature spanning –65°C to +150°C and maximum reverse leakage of 5.0μA at 25°C and 50μA at 100°C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	1000 V - Withstands peak reverse voltages up to 1000V in AC line rectification without breakdown.
I_O	1.5 A @ T_A = 70°C - Continuous average forward current rating under standard heatsinking conditions.
V_F	1.1 V @ I_F = 1.5A - Low conduction loss enabling efficient power delivery in 12–48V output supplies.
I_FSM	50 A - Handles short-duration inrush surges common during cold-start of switch-mode power supplies.
R_θJA	55 °C/W - Defines thermal rise per watt dissipated in still-air ambient; requires board-level copper area for sustained 1.5A operation.
C_T	20 pF @ 1MHz, 4V_R - Minimal junction capacitance avoids high-frequency noise coupling in EMI-sensitive designs.

Pinout & Package

Package: DO-15 molded plastic case (UL 94V-0), axial-leaded, cathode band marked on body. Lead finish: matte tin, solderable per MIL-STD-202 Method 208.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to AC source or transformer secondary; must withstand full surge current and reverse recovery stress.
Cathode	Forward current exit point	Connected to bulk capacitor or load return; polarity marking (band) ensures correct orientation in PCB layout.

Key Features

Feature	Design Value
Fast switching recovery	Enables higher efficiency than standard 1N400x series in 50/60Hz rectifiers with reduced switching loss.
50A surge rating	Supports reliable startup in power supplies with large input capacitors without fuse tripping or device failure.
Low reverse leakage	5.0 μA max at 25°C ensures minimal standby power loss in always-on systems like smart meters.
RoHS-compliant finish	Tin-plated leads meet EU Directive 2002/95/EC with exemptions applied per Annex Notes 5 and 7.

Applications

AC/DC Power Adapter Input Stage

Industrial PLC Power Supply

Use Scenario: Rectifying 115/230VAC mains input before bulk capacitor filtering in wall-wart adapters.

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

Use Value: 1000V V_RRM provides margin against line transients; 1.1V V_F limits conduction heating at 1.5A output.

Use Scenario: Converting unregulated AC to DC in programmable logic controller power modules.

IC Role / Device Role / Timing Role: Primary-side rectifier in isolated flyback or forward converter front-end.

Use Value: 50A I_FSM tolerates repeated motor contactor switching surges without degradation.

LED Driver Bulk Rectification

DC Motor Control Snubber Circuit

Use Scenario: Full-wave rectification feeding constant-current LED driver ICs in streetlight fixtures.

IC Role / Device Role / Timing Role: Line-frequency rectifier delivering stable DC bus to downstream buck or boost controllers.

Use Value: Low R_θJA (55°C/W) allows operation at 70°C ambient without forced cooling in enclosed housings.

Use Scenario: Freewheeling path across brushed DC motor windings during PWM commutation.

IC Role / Device Role / Timing Role: Clamp diode providing inductive energy recirculation path.

Use Value: Fast recovery minimizes voltage overshoot during turn-off; 1000V rating covers back-EMF spikes up to 800V.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N5408-T	3A I_O, same V_RRM (1000V), higher V_F (1.2V), larger DO-201AD package	Higher current capacity but requires more PCB real estate and thermal management	Select when >1.5A continuous output or higher surge margin is required.
UF5408-T	3A I_O, 1000V V_RRM, ultrafast recovery (~75ns), higher V_F (1.7V)	Optimized for high-frequency switching; not recommended for pure 50/60Hz rectification due to cost/performance trade-off	Select only if used in PFC or high-frequency auxiliary supplies where fast recovery reduces losses.

Compared with 1N5399-T, 1N5408-T offers higher current headroom at the cost of larger footprint and slightly higher conduction loss, while UF5408-T trades increased forward loss for nanosecond-scale recovery-making it over-specified for standard line-frequency use.

FAQ

What is the maximum allowable ambient temperature for continuous 1.5A operation?

The 1N5399-T is rated for 1.5A average forward current at T_A = 70°C. Above this, current must be linearly derated per Figure 1 in the datasheet: at 100°C ambient, maximum I_O drops to approximately 1.1A. Adequate PCB copper area and airflow are essential to maintain safe junction temperature.

Can 1N5399-T replace 1N4007 in existing designs?

Yes, 1N5399-T is a direct functional upgrade to 1N4007: both share 1000V V_RRM, but 1N5399-T offers higher I_O (1.5A vs. 1.0A), lower V_F (1.1V vs. 1.2V), and superior surge rating (50A vs. 30A). No layout change is needed-it uses the same DO-15 package and cathode band marking.

Is 1N5399-T lead-free and RoHS compliant?

Yes, 1N5399-T features a lead-free, RoHS-compliant tin finish per EU Directive 2002/95/EC, with exemptions applied for glass and high-temperature solder per Annex Notes 5 and 7. It meets J-STD-020C moisture sensitivity Level 1 and is qualified for standard reflow and wave soldering processes.

Does 1N5399-T have a specified reverse recovery time?

No, the datasheet does not specify reverse recovery time (t_rr) for 1N5399-T. It is classified as a general-purpose rectifier-not an ultrafast or fast-recovery type. For applications requiring t_rr < 500ns, consider alternatives such as UF5408-T or BYV26E, which provide documented recovery characteristics.
