Product details
Overview
1N5401G-T from Diodes Incorporated is a 100 V peak repetitive reverse voltage, 3.0 A average forward rectified current glass passivated silicon rectifier diode in DO-201AD package, with 1.1 V forward voltage at 3.0 A and 125 A non-repetitive surge capability, used in AC/DC power supplies and DC motor freewheeling circuits.
For engineers reviewing the 1N5401G-T datasheet, 1N5401G-T pinout, 1N5401G-T application, or 1N5401G-T equivalent, this page delivers verified electrical ratings, thermal resistance (16 °C/W), reverse recovery time (2.0 μs), capacitance (40 pF), and RoHS-compliant packaging details for reliable power conversion design validation.
Technical Context
This axial-lead rectifier operates in single-phase, half-wave configurations at 60 Hz with resistive or inductive loads. Its glass passivated die construction ensures stable junction performance under thermal cycling and humidity exposure.
The device exhibits 5.0 μA peak reverse current at 25°C and 100 μA at 125°C under rated 100 V DC blocking voltage, with typical reverse recovery time measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A.

Applications
| AC/DC Power Supply Input Stage | DC Motor Freewheeling Protection |
|---|---|
Use Scenario: Full-wave bridge rectification of 120 VAC mains input in offline SMPS and linear power supplies. IC Role / Device Role / Timing Role: Discrete rectifier conducting during positive half-cycles, blocking reverse voltage during negative half-cycles. Use Value: Low 1.1 V forward drop minimizes conduction loss at 3 A load; 100 V VRRM safely handles 120 VAC peak (170 V) with margin. | Use Scenario: Flyback diode across brushed DC motor windings to suppress inductive kickback during PWM switching. IC Role / Device Role / Timing Role: Clamping path for stored inductive energy, preventing MOSFET drain overvoltage during turn-off. Use Value: 125 A IFSM absorbs short-duration back-EMF transients; 2.0 μs trr limits switching loss during rapid PWM transitions. |
| Capacitor-Input Filter Stage | Industrial Control Power Rails |
Use Scenario: Output rectification in capacitor-input filter configuration feeding regulated 24 VDC control logic rails. IC Role / Device Role / Timing Role: Delivers pulsed charging current to bulk electrolytic capacitors while blocking reverse discharge. Use Value: 40 pF junction capacitance reduces high-frequency ripple coupling into sensitive analog circuitry downstream. | Use Scenario: Primary DC feed for PLC I/O modules and sensor interface boards operating in factory-floor environments. IC Role / Device Role / Timing Role: Mainline rectifier providing robust, thermally stable DC bus under variable load and ambient conditions. Use Value: -65°C to +150°C operating range supports deployment in uncontrolled enclosures; DO-201AD mechanical ruggedness resists vibration-induced failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5401RLG | Same electrical specs; TO-220AC package with mounting tab, higher RθJC but lower RθJA with heatsink | Better thermal management in high-power continuous duty; requires PCB mounting hardware | Select when >1 W dissipation demands heatsink attachment and board space permits larger footprint |
| SB3100 | Schottky diode: 100 V VRRM, 3 A IO, 0.85 V VF, but 500 μA IR at 25°C vs. 5 μA for 1N5401G-T | Lower conduction loss but higher leakage; unsuitable for high-temperature or low-leakage hold-up circuits | Select only where efficiency dominates leakage sensitivity, e.g., low-voltage, high-frequency DC/DC front-end stages |
Compared with 1N5401RLG, the 1N5401G-T offers tape-and-reel automation compatibility and smaller DO-201AD footprint; compared with SB3100, it provides superior high-temperature leakage performance and ruggedness for general-purpose industrial rectification.

FAQ
What is the maximum allowable ambient temperature for continuous 3.0 A operation?
The 1N5401G-T is rated for 3.0 A average forward current at TA = 55°C. Above this, current must be linearly derated per Figure 1 in the datasheet: at 75°C ambient, max IO drops to ~2.3 A; at 100°C, it falls to ~1.5 A. Derating assumes 9.5 mm lead length maintained at ambient temperature.
Can the 1N5401G-T be used in capacitor-input filter circuits without derating?
No - the datasheet explicitly requires 20% current derating for capacitive loads due to high peak charging currents. At full 3.0 A average output, the peak current may exceed 10 A, risking thermal overload or premature failure if not accounted for in layout and heatsinking.
Is the DO-201AD package compatible with standard axial-lead automated insertion equipment?
Yes - the DO-201AD outline (25.4 mm body length, 7.2–9.5 mm body diameter) conforms to IPC-7351 standards for axial components. Lead spacing is 10.16 mm (0.4 inch), matching common wave-solder and auto-insertion tooling for through-hole assembly.
How does the 2.0 μs reverse recovery time affect EMI in switching power supplies?
A 2.0 μs trr introduces measurable switching noise during turn-off, especially in high-frequency (>20 kHz) converters. It increases diode switching loss and generates broadband EMI peaks near 0.35/trr (~175 kHz); snubbers or synchronous rectification should be considered for noise-sensitive designs.
