Product details
Overview
1N5402 from Diodes Incorporated is a 3.0A, 200V peak repetitive reverse voltage general-purpose silicon rectifier diode in DO-201AD package, featuring 1.0V forward voltage at 3.0A, 200A non-repetitive surge capability, and 10µA reverse leakage at 25°C - used in AC/DC power supplies, battery chargers, and DC motor control circuits.
For engineers reviewing the 1N5402 datasheet, 1N5402 pinout, 1N5402 application, or 1N5402 equivalent, key selection criteria include its 200V VRRM, 3.0A average forward current at 105°C, thermal resistance of 15°C/W, DO-201AD mechanical outline, and RoHS-compliant tin-plated leads.
Technical Context
The 1N5402 operates as a single-phase, half-wave silicon rectifier with diffused junction construction, optimized for resistive or inductive loads at 60Hz. Its design supports full-wave bridge configurations and requires 20% current derating under capacitive load conditions.
Thermal performance is defined by junction-to-ambient thermal resistance (15°C/W) and operating temperature range (–65°C to +150°C), with validated surge robustness up to 200A (8.3ms half-sine) and low reverse leakage (10µA at 25°C, 100µA at 150°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum peak reverse voltage before breakdown; defines safe AC input voltage limit in rectifier designs. |
| IO | 3.0 A - Average forward current rating at 105°C case temperature; determines continuous DC output capability. |
| VF @ 3.0A | 1.0 V - Forward voltage drop at rated current; directly impacts conduction loss and thermal dissipation. |
| IFSM | 200 A - Non-repetitive surge current capacity (8.3ms); enables tolerance to line transients and inrush events. |
| IR @ 25°C | 10 µA - Reverse leakage current at rated DC blocking voltage; critical for low-power standby and high-impedance circuits. |
| RθJA | 15 °C/W - Junction-to-ambient thermal resistance; sets minimum heatsinking requirement for 3.0A operation. |
Pinout & Package
Package: DO-201AD molded plastic case (UL 94V-0), 1.1g weight, cathode band polarity marking, tin-plated solderable leads per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connects to AC source or transformer secondary; must withstand full surge current and reverse recovery stress. |
| Cathode | Forward current exit point | Connects to load or filter capacitor; marked with band; carries full output current and defines reference for reverse bias. |
Key Features
| Feature | Design Value |
|---|---|
| Diffused junction construction | Enables stable reverse breakdown behavior and improved surge endurance over alloy-junction alternatives. |
| 200A surge rating (8.3ms) | Supports reliable operation during cold-start surges in offline power supplies without external fusing. |
| Low 10µA reverse leakage @ 25°C | Minimizes standby power loss in battery-backed or energy-sensitive applications. |
| DO-201AD package with 94V-0 rating | Provides flame-retardant mechanical integrity and standardized mounting for through-hole PCB assembly. |
Applications
| AC/DC Power Supply Input Stage | Battery Charger Rectification |
|---|---|
Use Scenario: Converts 120VAC/240VAC mains to pulsating DC prior to filtering and regulation. IC Role / Device Role / Timing Role: Primary rectifier in single-phase half-wave or full-wave bridge configuration. Use Value: 200V VRRM and 3.0A IO support universal-input 12–24V output chargers up to 72W continuous. | Use Scenario: Rectifies transformer-derived AC for lead-acid or NiMH battery charging circuits. IC Role / Device Role / Timing Role: Unidirectional current gate enabling controlled DC delivery to battery terminals. Use Value: Low 1.0V VF reduces heat generation during prolonged charge cycles, improving thermal margin. |
| DC Motor Drive Freewheeling | Industrial Control Signal Conditioning |
Use Scenario: Suppresses inductive kickback across brushed DC motor windings during PWM switching. IC Role / Device Role / Timing Role: Freewheeling diode providing low-impedance path for stored magnetic energy. Use Value: 200A IFSM safely clamps transient spikes from motors up to 1/4 HP without degradation. | Use Scenario: Protects analog input stages from accidental AC coupling or ESD-induced reverse polarity. IC Role / Device Role / Timing Role: Polarity protection and overvoltage clamp in sensor interface front-ends. Use Value: 10µA IR ensures minimal loading on high-impedance signal paths (<1MΩ) at room temperature. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5404 | 400V VRRM, same IO, VF, and package | Higher reverse voltage margin for 230VAC+ systems with poor regulation or surge exposure | Select when system peak reverse stress exceeds 200V but thermal and current requirements match. |
| 1N5401 | 100V VRRM, otherwise identical electrical and mechanical specs | Suitable only for low-voltage AC inputs (e.g., 12–24VAC control transformers) | Choose for cost-sensitive 100V-class designs where 200V rating is unnecessary overhead. |
Compared with 1N5404 and 1N5401, the 1N5402 offers optimal balance of reverse voltage headroom and conduction efficiency for 120VAC-fed power supplies - avoiding over-specification while maintaining safety margin against line transients.

FAQ
Is the 1N5402 RoHS compliant?
Yes, the 1N5402 features a lead-free finish and is RoHS compliant per EU Directive Annex Notes 5 and 7, with exemptions applied for glass and high-temperature solder. Tin-plated leads meet MIL-STD-202 Method 208 solderability requirements.
What is the maximum ambient temperature for full 3.0A operation?
The 1N5402 delivers its full 3.0A average forward current rating only when leads are maintained at ambient temperature at a distance of 9.5mm from the case, corresponding to a maximum ambient temperature of 105°C per the derating curve in the datasheet.
Can the 1N5402 be used in capacitive-load applications?
Yes, but with 20% current derating applied to the 3.0A rating due to higher peak currents inherent in capacitive-input filter designs - resulting in a maximum recommended average current of 2.4A for such configurations.
How does the 1N5402 differ from Schottky rectifiers with similar current ratings?
Unlike Schottky diodes, the 1N5402 uses a silicon PN junction with higher VF (~1.0V vs. ~0.4–0.6V) but superior reverse voltage capability (200V vs. typically ≤100V) and negligible reverse recovery charge - making it preferable in high-VR, low-frequency, high-surge applications.
