Product details

Overview

1N5407-E3/73 from Vishay General Semiconductor is a general-purpose plastic rectifier diode in DO-201AD package, rated for 800 V repetitive peak reverse voltage (V_RRM), 3.0 A average forward current (I_F(AV)), and 200 A non-repetitive surge current (I_FSM). It delivers low forward voltage drop (1.2 V at 3.0 A) and low leakage (5.0 μA at 25 °C), suited for AC/DC power supply input rectification in industrial power adapters.

For engineers reviewing the 1N5407-E3/73 datasheet, 1N5407-E3/73 pinout, 1N5407-E3/73 application, or 1N5407-E3/73 equivalent, key selection criteria include V_RRM = 800 V, I_F(AV) = 3.0 A, thermal resistance R_θJA = 20 °C/W, junction temperature range (–50 to +150 °C), and DO-201AD mechanical compatibility with PCB-mounted heat sinking.

Technical Context

This single-diode rectifier operates in unidirectional conduction mode with cathode-indicating band polarity. Its 1.2 V forward voltage at 3.0 A enables efficient power conversion in linear and switching power supplies, while 5.0 μA reverse leakage at 25 °C supports stable DC bus hold-up under light-load conditions.

The device uses molded epoxy encapsulation (UL 94 V-0 rated) and matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. E3 suffix confirms RoHS compliance and JESD 201 Class 1A whisker resistance, supporting reliable long-term solder joint integrity in commercial-grade applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	800 V - blocks up to 800 V reverse voltage without breakdown, suitable for 560 V RMS input circuits
I_F(AV)	3.0 A - continuous forward current rating at 105 °C lead temperature, defines max steady-state power handling
I_FSM	200 A - withstands 8.3 ms half-sine surge, critical for inrush current protection in transformer-coupled supplies
V_F	1.2 V @ 3.0 A - low conduction loss reduces thermal stress and improves efficiency in high-current rectification
I_R	5.0 μA @ 25 °C - minimal reverse leakage preserves output regulation and minimizes standby power loss
T_J max.	+150 °C - enables operation in high-ambient environments such as enclosed industrial enclosures

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N5407G	V_RRM = 800 V, same I_F(AV)/I_FSM, but Pb-free matte tin plating per JESD 201 Class 2A (higher whisker threshold)	Preferred where extended reliability under high-humidity storage is required	Select 1N5407G for automotive or medical-adjacent applications demanding enhanced whisker resistance
STTH3R08	Ultrafast recovery (t_rr = 75 ns), lower V_F (1.15 V), but lower I_FSM (120 A) and same V_RRM	Better suited for high-frequency SMPS (>50 kHz); less robust for 50/60 Hz transformer surges	Choose STTH3R08 only when switching frequency exceeds 20 kHz and surge immunity is secondary to recovery speed

Compared with 1N5407-E3/73, 1N5407G offers identical electrical specs with upgraded whisker resistance, while STTH3R08 trades surge ruggedness for faster recovery-making the former a drop-in reliability upgrade and the latter a topology-specific alternative for high-frequency designs.

FAQ

What is the maximum junction temperature rating for the 1N5407-E3/73?

The 1N5407-E3/73 has a maximum junction temperature (T_J) of +150 °C and a minimum of –50 °C. This wide operating range allows deployment in harsh environments such as enclosed industrial control panels or outdoor UPS cabinets. Thermal design must ensure that power dissipation-calculated from V_F × I_F and ambient conditions-does not exceed this limit, especially under sustained 3.0 A load with limited heatsinking.

Is the 1N5407-E3/73 RoHS-compliant and lead-free?

Yes, the 1N5407-E3/73 is RoHS-compliant and lead-free. The "E3" suffix explicitly denotes Vishay's commercial-grade, RoHS-compliant construction with matte tin-plated leads meeting J-STD-002 solderability and JESD 201 Class 1A whisker resistance requirements. It is suitable for lead-free reflow and wave soldering processes without compromising joint integrity or long-term reliability.

What does the "/73" suffix indicate in 1N5407-E3/73?

The "/73" suffix in 1N5407-E3/73 specifies the packaging format: 1000-piece ammo pack. This differs from "/54", which denotes 1400-piece 13-inch paper tape and reel. Both share identical electrical and mechanical specifications; the suffix solely identifies logistics configuration and is critical for automated assembly line compatibility and inventory planning.

How does the 1N5407-E3/73 compare to the 1N5408-E3/73 in terms of voltage rating?

The 1N5407-E3/73 is rated for 800 V repetitive peak reverse voltage (V_RRM), whereas the 1N5408-E3/73 is rated for 1000 V V_RRM. All other key parameters-including I_F(AV) = 3.0 A, I_FSM = 200 A, V_F = 1.2 V, and DO-201AD package-are identical. Selection between them depends strictly on required reverse voltage margin relative to system peak AC voltage and transient overshoot levels.

Can the 1N5407-E3/73 be used in surface-mount designs?

No, the 1N5407-E3/73 is an axial-lead DO-201AD through-hole device and is not designed for surface-mount assembly. Its mechanical outline requires 0.375" (9.5 mm) lead length and PCB mounting with copper heat sinks for thermal management. For SMT alternatives, consider Vishay's VS-1N5407-M3/73 (same die in DO-214AB package), which maintains identical electrical ratings but uses gull-wing leads compatible with reflow soldering.
