Product details
Overview
1N5406G-T from Diodes Incorporated is a glass passivated silicon rectifier diode rated for 3.0A average forward current, 600V peak repetitive reverse voltage, and 125A non-repetitive surge current, used in AC/DC power supply front-end rectification and DC bus conditioning circuits.
For engineers reviewing the 1N5406G-T datasheet, 1N5406G-T pinout, 1N5406G-T application, or 1N5406G-T equivalent, key selection criteria include VRRM=600V, IF(AV)=3.0A at TA=55°C, VF=1.1V @ 3.0A, trr=2.0μs, and DO-201AD package thermal resistance of 16°C/W.
Technical Context
This device operates as a single-phase, half-wave rectifier under 60Hz resistive or inductive loads, with derating required for capacitive loads (−20% current). Its glass passivated junction ensures stable reverse leakage (IRM ≤5.0μA @25°C) and robust surge tolerance (125A, 8.3ms sine wave).
The DO-201AD package supports lead-free soldering per MIL-STD-202 Method 208, with cathode band polarity marking and UL 94V-0 flammability rating. Thermal performance is defined with leads held at ambient temperature 9.5mm from case per JEDEC standard.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum peak reverse voltage before breakdown; defines safe AC input voltage handling (e.g., 424V RMS line) |
| IF(AV) | 3.0 A @ TA = 55°C - Continuous DC output current capability with specified thermal mounting condition |
| VF | 1.1 V @ IF = 3.0A - Forward conduction loss directly impacts power dissipation (3.3W typical at full load) |
| IFSM | 125 A (8.3ms) - Surge withstand for inrush current during cold-start or capacitor charging |
| trr | 2.0 μs - Reverse recovery time limits usable frequency range; suitable for 50/60Hz, marginal for 400Hz |
| RθJA | 16 °C/W - Junction-to-ambient thermal resistance under standard test conditions (9.5mm lead length) |
Pinout & Package
Package: DO-201AD molded plastic case, UL 94V-0 rated, matte tin-plated leads, cathode identified by band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC source or transformer secondary; must handle full surge current path |
| Cathode | Forward current exit point | Marked with band; connects to DC bus or filter capacitor positive terminal |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Enhanced moisture resistance and long-term reliability in humid industrial environments |
| 125A surge rating | Withstands repeated cold-start surges without degradation in power supply input stages |
| RoHS-compliant matte tin plating | Ensures consistent solderability and intermetallic formation control in lead-free reflow |
| Low RθJA (16°C/W) | Enables compact heatsinking or natural convection cooling in space-constrained enclosures |
Applications
| AC-DC Power Adapters | Industrial Motor Drive DC Bus |
|---|---|
Use Scenario: 60Hz mains-fed wall adapters delivering 5–24V DC output up to 3A. IC Role / Device Role / Timing Role: Primary-side rectifier converting transformer secondary AC to pulsating DC. Use Value: 600V VRRM provides 2× safety margin over 230VAC input; 1.1V VF minimizes heat generation in unventilated housings. | Use Scenario: DC link rectification in 3-phase inverter pre-charging and braking circuits. IC Role / Device Role / Timing Role: Uncontrolled rectifier feeding bulk storage capacitors prior to IGBT switching. Use Value: 125A IFSM handles high inrush during capacitor pre-charge; DO-201AD package allows direct PCB mounting near bus terminals. |
| LED Streetlight Drivers | UPS Input Stage Rectification |
Use Scenario: Off-line LED drivers operating from 100–277VAC with passive PFC. IC Role / Device Role / Timing Role: Bridge or single-diode rectifier in valley-fill or choke-input configurations. Use Value: 2.0μs trr avoids excessive switching loss in quasi-resonant topologies; 5μA IRM ensures low standby leakage. | Use Scenario: Line-powered UPS systems requiring high-reliability input rectification. IC Role / Device Role / Timing Role: Main AC input rectifier feeding battery charger and inverter DC bus. Use Value: −65°C to +150°C operating range supports wide ambient deployment; UL 94V-0 housing meets safety certification requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5406RLG | Same electrical specs; DO-201AD package but tape-and-reel packaging differs (1.2K vs 1.0K per reel) | No functional difference; identical thermal and electrical behavior in circuit | Select when matching existing reel-based SMT assembly lines with different reel size requirements |
| GBU6K | Bridge configuration (4-pin), 600V, 6A avg, VF=1.1V, trr=2.0μs - higher current, integrated bridge | Replaces discrete 4-diode bridge; reduces PCB footprint but requires 4-terminal layout | Choose for new designs needing full-wave rectification without discrete layout complexity |
Compared with 1N5406G-T, 1N5406RLG offers identical performance in alternate packaging, while GBU6K delivers double current and full-wave integration at the cost of layout flexibility and discrete replacement compatibility.

FAQ
What is the maximum allowable junction temperature for 1N5406G-T?
The absolute maximum junction temperature is +150°C, as specified in the datasheet. Operation above this limit risks irreversible parametric shift or catastrophic failure. Derating curves show that at TA=55°C, full 3.0A current is permitted only with proper thermal management-leads must be maintained at ambient temperature at 9.5mm from the case body.
Can 1N5406G-T replace 1N5406 in legacy designs?
Yes-1N5406G-T is a direct drop-in replacement for 1N5406, sharing identical electrical specifications, DO-201AD package dimensions, and pinout. The "G" suffix denotes glass passivation (improved reliability), and "T" indicates tape-and-reel packaging; no circuit redesign is needed.
Is 1N5406G-T suitable for high-frequency switching applications?
No-it is optimized for 50/60Hz line-frequency rectification. With a 2.0μs reverse recovery time, it exhibits significant switching loss above ~400Hz and is not recommended for SMPS primary-side rectification or PWM-controlled rectifiers where fast recovery or ultrafast diodes are required.
How does the DO-201AD package affect thermal performance?
The DO-201AD package has a junction-to-ambient thermal resistance of 16°C/W under JEDEC-standard test conditions (leads held at ambient 9.5mm from case). Real-world PCB copper area, airflow, and mounting method significantly impact actual thermal resistance-adding thermal relief pads or using thicker copper can reduce effective RθJA by 30–50%.
