Product details
Overview
2A05-T from Diodes Incorporated is a 600 V peak repetitive reverse voltage, 2.0 A average forward rectified current DO-15 packaged silicon rectifier diode with 1.1 V forward voltage at 2.0 A, 70 A non-repetitive surge capability, and 5.0 μA reverse leakage at 25°C - used in AC/DC front-end rectification for industrial power supplies and LED drivers.
For engineers reviewing the 2A05-T datasheet, 2A05-T pinout, 2A05-T application, or 2A05-T equivalent, key selection criteria include VRRM derating for capacitive loads (−20% current), thermal resistance (60°C/W), and DO-15 mechanical compatibility with legacy through-hole layouts.
Technical Context
This device is a standard single-phase, half-wave silicon rectifier optimized for 60 Hz line-frequency operation under resistive or inductive loads. Its diffused junction enables stable thermal performance up to +150°C junction temperature and supports surge currents up to 70 A for 8.3 ms.
The 2A05-T exhibits 15 pF typical junction capacitance at 1 MHz and 4.0 V reverse bias, making it suitable for low-noise rectification where parasitic capacitance impacts EMI filtering. Polarity is marked by a cathode band; terminals are bright tin-plated for MIL-STD-202-compliant solderability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum peak reverse voltage before breakdown; sets minimum insulation clearance for 400 VAC input designs. |
| IO @ TA = 55°C | 2.0 A - continuous DC output current rating at 55°C ambient; requires heatsinking or airflow above this temperature. |
| VFM @ IF = 2.0 A | 1.1 V - forward drop determines conduction loss (2.2 W at full load) and thermal rise in linear-regulated supplies. |
| IFSM | 70 A - surge rating defines inrush tolerance during cold-start of capacitive-input rectifiers. |
| RθJA | 60 °C/W - junction-to-ambient thermal resistance with 9.5 mm lead length; used to calculate max junction temp under real PCB layout. |
| IRM @ 25°C | 5.0 μA - reverse leakage ensures minimal standby power loss in high-impedance hold-up circuits. |
Pinout & Package
Package: DO-15 molded plastic case (UL 94V-0), axial lead configuration with cathode band marking. Weight ≈ 0.4 g. Moisture sensitivity level 1 per J-STD-020C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | AC input connection point | Accepts incoming alternating waveform; must withstand full VRRM during negative half-cycle. |
| Cathode (banded end) | DC output connection point | Delivers rectified unidirectional current; polarity marking prevents reverse installation in PCB assembly. |
Key Features
| Feature | Design Value |
|---|---|
| Diffused junction construction | Enables stable reverse recovery and consistent VRRM across temperature and process variation. |
| 70 A IFSM surge rating | Supports reliable startup into bulk capacitor loads without degradation in 115/230 VAC SMPS front ends. |
| DO-15 package with 9.5 mm lead length | Provides standardized thermal path for manual or wave-soldered mounting; compatible with legacy through-hole tooling. |
| Bright tin-plated leads | Ensures repeatable wetting and joint integrity per MIL-STD-202 Method 208, critical for high-reliability industrial assemblies. |
Applications
| Industrial AC/DC Power Supply | LED Driver Input Stage |
|---|---|
Use Scenario: Rectifying 50/60 Hz mains input in open-frame 20–50 W industrial power supplies. IC Role / Device Role / Timing Role: Primary-side uncontrolled rectifier converting AC to pulsating DC prior to bulk capacitor filtering. Use Value: 600 V VRRM provides 2× safety margin over 230 VAC RMS, while 2.0 A IO supports sustained load without forced cooling. | Use Scenario: Input rectification in constant-current LED drivers for street lighting and high-bay fixtures. IC Role / Device Role / Timing Role: Front-end diode bridge leg handling line-frequency ripple and cold-start surges. Use Value: 70 A IFSM tolerates repeated capacitor charging events; low VFM minimizes heat generation near thermally sensitive LEDs. |
| Appliance Motor Control Board | UPS Battery Charging Circuit |
Use Scenario: Half-wave rectification for auxiliary control logic power in washing machine or HVAC motor drive boards. IC Role / Device Role / Timing Role: Isolated low-power DC rail generation from mains via transformer secondary. Use Value: DO-15 footprint allows compact placement near transformer; −65°C to +150°C rating survives under-hood thermal cycling. | Use Scenario: AC-to-DC conversion in offline battery charger modules for small UPS systems. IC Role / Device Role / Timing Role: Unidirectional current path enabling transformer-isolated charging with minimal conduction loss. Use Value: 5.0 μA IRM at 25°C reduces no-load power draw; RθJA = 60°C/W simplifies thermal design in enclosed enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06 | TO-220AC package, 600 V VRRM, 2.0 A IO, but 1.7 V VFM at 2.0 A - higher conduction loss. | Requires PCB cutout and heatsink; unsuitable for space-constrained DO-15 layouts. | Select when higher surge robustness (100 A IFSM) and heatsink-mounting are prioritized over board area. |
| ON Semi MUR260 | Ultrafast recovery (trr = 50 ns), same DO-15 package, 600 V VRRM, but 1.25 V VFM - trade-off between switching noise and efficiency. | Preferred in PFC stages or high-frequency flyback snubbers where reverse recovery matters. | Choose only if circuit operates >20 kHz or demands reduced EMI; otherwise 2A05-T's standard recovery is sufficient and lower-cost. |
Compared with STTH2R06 and MUR260, the 2A05-T delivers optimal balance of cost, thermal profile, and footprint for fixed-frequency 50/60 Hz rectification - avoiding unnecessary complexity or overhead where ultrafast recovery or TO-220 mounting isn't required.

FAQ
Is the 2A05-T RoHS compliant?
Yes, the 2A05-T features a lead-free finish and is RoHS compliant per EU Directive Annex Notes 5 and 7, with high-temperature solder exemption applied. The device meets RoHS revision 13.2.2003 and carries UL 94V-0 flammability rating on its molded plastic case.
What is the maximum operating temperature for the 2A05-T?
The 2A05-T has an operating and storage temperature range of −65°C to +150°C. Its junction temperature must remain within this limit; at 2.0 A load and 55°C ambient, thermal calculations using RθJA = 60°C/W show Tj ≈ 175°C - exceeding rating, so derating or heatsinking is required above 55°C ambient.
Can the 2A05-T be used in capacitive-input filter circuits?
Yes, but with 20% current derating per datasheet guidance. For example, at 2.0 A rated IO, only 1.6 A should be drawn in capacitive-input configurations due to increased peak current stress and elevated RMS heating in the diode.
Does the 2A05-T have a specified reverse recovery time (trr)?
No - the 2A05-T is a standard recovery rectifier; trr is not characterized or guaranteed in the datasheet. It is intended for 50/60 Hz operation, not high-frequency switching. For circuits requiring fast recovery, alternatives like MUR260 (50 ns trr) should be selected instead.
