Product details

Overview

RL205-T from Diodes Incorporated is a 2.0A, 600V general-purpose silicon rectifier diode in DO-15 package, designed for AC/DC conversion in power supplies and input stage rectification. It delivers 1.0V max forward voltage at 2.0A DC, supports 70A non-repetitive surge current, and operates from –65°C to +150°C ambient.

For engineers reviewing the RL205-T datasheet, RL205-T pinout, RL205-T application, or RL205-T equivalent, key selection factors include peak reverse voltage rating (600V), thermal resistance (40°C/W), junction capacitance (40pF @ 4V), reverse leakage (5.0mA @ 25°C), and DO-15 mechanical compatibility with through-hole PCB layouts.

Technical Context

This axial-lead rectifier operates in single-phase, half-wave 60Hz configurations with resistive or inductive loads. Its 600V V_RRM enables use in universal-input offline power supplies up to 264V_AC, while the 40°C/W R_θJC supports thermal management with minimal heatsinking at full 2.0A average current.

The device exhibits low 1.0V forward drop at rated DC current and maintains stable reverse characteristics up to 125°C (50mA IR), making it suitable for industrial power adapters where reliability under sustained load and temperature stress is required.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - Withstands peak reverse voltage in 264V_AC input circuits without breakdown
I_(AV)	2.0 A @ 50°C ambient - Sustains continuous rectified output in compact power supplies
V_F	1.0 V max @ 2.0A DC - Minimizes conduction loss and self-heating during operation
I_FSM	70 A @ 8.3 ms - Survives cold-start inrush surges in transformer-coupled supplies
R_θJC	40 °C/W - Enables direct PCB copper pour cooling without dedicated heatsink
C_J	40 pF @ 4V - Limits high-frequency noise coupling in EMI-sensitive SMPS front-ends

Pinout & Package

DO-15 molded plastic package with axial leads; cathode indicated by color band; lead length 9.5 mm; weight ≈ 0.4 g; UL 94V-0 flammability rating.

Pin/Terminal	Circuit Role	Design Meaning

Key Features

Feature	Design Value
Low forward voltage drop	1.0 V max at 2.0A ensures ≤2W conduction loss at full load, reducing thermal design burden

Applications

AC-DC Power Adapters

Industrial Motor Control Inputs

Use Scenario: 115/230V_AC input rectification in wall-mounted power adapters for consumer electronics.

IC Role / Device Role / Timing Role: Primary-side power diode converting AC line to pulsating DC before bulk capacitor filtering.

Use Value: 600V V_RRM provides margin for 264V_AC peaks; 1.0V V_F limits heat generation in space-constrained enclosures.

Use Scenario: Input rectification for 3-phase bridge-fed DC bus in variable frequency drives.

IC Role / Device Role / Timing Role: Single-phase leg in multi-diode rectifier stacks handling auxiliary control power.

Use Value: 70A I_FSM tolerates transient overloads during motor startup; DO-15 axial form factor simplifies manual assembly on control board.

LED Driver Front-Ends

UPS Battery Charging Circuits

Use Scenario: Off-line LED driver with passive PFC and flyback topology.

IC Role / Device Role / Timing Role: Bridge input diode conducting during positive half-cycles before bulk storage.

Use Value: 40pF junction capacitance minimizes high-frequency switching noise injection into feedback loop.

Use Scenario: Mains-powered battery charger for sealed lead-acid backup systems.

IC Role / Device Role / Timing Role: Unidirectional current path from rectified AC to charge controller IC input.

Use Value: 5.0mA max reverse leakage at 25°C prevents significant standby drain when mains is disconnected.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
2A05G	Same DO-15 package, identical 600V V_RRM and 2.0A I_(AV), but lower 0.95V typical V_F and 50A I_FSM	Optimized for higher-efficiency, lower-surge designs; slightly reduced surge margin	Select when prioritizing conduction loss over surge robustness
RS2M	DO-15, 600V V_RRM, 2.0A I_(AV), but faster recovery time (500ns vs. standard ~2μs) and higher 1.1V V_F	Suitable for higher-frequency rectification (e.g., 20–50kHz SMPS), not ideal for 50/60Hz line frequency	Select only if operating above 1kHz; avoid for traditional linear supply use

Compared with RL205-T, 2A05G offers better efficiency at cost of surge margin, while RS2M trades forward drop for speed-neither is drop-in compatible without verifying thermal and dynamic behavior in the target circuit.

FAQ

Is RL205-T still recommended for new designs?

No. Diodes Incorporated explicitly marks RL205-T as discontinued and "not recommended for new designs" in DS28005 Rev. 7. The 2A05G is the designated replacement with improved forward voltage and surge rating. Legacy RL205-T stock remains available for repair and continuity, but new designs should adopt the 2A05G or equivalent qualified rectifier.

What is the maximum ambient temperature for full 2.0A operation?

RL205-T delivers its rated 2.0A average forward current only at T_A = 50°C, as specified in the datasheet. Derating begins above this point: at 75°C ambient, maximum I_(AV) drops to approximately 1.5A, and at 100°C, it falls below 1.0A. Thermal design must ensure case temperature stays within limits using PCB copper area or airflow.

Can RL205-T be used in a full-wave bridge configuration?

Yes-RL205-T is a single diode and can be used in discrete full-wave bridge assemblies. Four RL205-T units may replace a single 600V/2A bridge rectifier (e.g., GBU6K), provided layout accommodates axial leads and thermal coupling between devices is managed. However, integrated bridges offer tighter matching and smaller footprint.

Does RL205-T meet RoHS and REACH requirements?

Yes. RL205-T is RoHS-compliant and REACH-conformant per Diodes Incorporated's product compliance documentation. Lead-free soldering is supported per MIL-STD-202 Method 208, and the DO-15 package contains no intentionally added restricted substances above threshold limits.
