Product details
Overview
RS605 from Diodes Incorporated is a 600V, 6.0A single-phase bridge rectifier in RS-6 molded plastic package, with 250A surge rating and 1.0V forward voltage drop per diode at 3.0A, used for AC-to-DC conversion in offline power supplies and industrial motor controls.
For engineers reviewing the RS605 datasheet, RS605 pinout, RS605 application, or RS605 equivalent, key selection criteria include peak reverse voltage (600V), average forward current (6.0A @ TC=100°C), thermal resistance (4.7°C/W), surge capability (250A, 8.3ms), and UL 94V-0 flammability rating.
Technical Context
The RS605 integrates four silicon junction diodes in a single-phase full-wave bridge configuration, optimized for resistive or inductive loads at 60Hz. It operates across -55°C to +125°C junction temperature and supports PCB mounting in any orientation.
Thermal performance is defined by junction-to-case resistance of 4.7°C/W per diode; derating curves specify 6.0A average output only when case temperature is held at 100°C. Capacitive loads require 20% current derating per datasheet guidance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum recurrent peak reverse voltage per diode; defines safe AC input voltage ceiling before breakdown. |
| I(AV) | 6.0 A @ TC = 100°C - Continuous DC output current capability when heatsink maintains case at 100°C. |
| IFSM | 250 A, 8.3 ms - Non-repetitive surge withstand for line transients or inrush without failure. |
| VF | 1.0 V @ 3.0A - Forward voltage per diode; determines conduction loss and thermal load at rated current. |
| RJC | 4.7 °C/W - Junction-to-case thermal resistance; sets minimum heatsink requirement for thermal management. |
| IR | 10 µA @ 600V, 25°C - Reverse leakage per diode; impacts standby power and high-impedance sensing integrity. |
Pinout & Package
Package: RS-6 molded plastic case with solderable axial leads (MIL-STD-202, Method 208 compliant), UL 94V-0 rated, approx. 8.0 g weight, mountable in any orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ~ (AC1) | AC input terminal 1 | One side of AC input winding; connects to transformer secondary or line filter output. |
| ~ (AC2) | AC input terminal 2 | Other side of AC input winding; completes full-wave bridge AC path. |
| + | DC positive output | Rectified anode-side output node; feeds bulk capacitor or downstream regulator. |
| - | DC negative output | Rectified cathode-side return node; serves as system ground reference for DC bus. |
Key Features
| Feature | Design Value |
|---|---|
| UL Recognized (File #94661) | Meets safety requirements for end-equipment certification in industrial and consumer power supplies. |
| Surge Overload Rating | 250A peak (8.3ms half-sine) enables robustness against lightning-induced surges and motor startup currents. |
| Low VF per element | 1.0V at 3.0A reduces conduction loss by ~15% vs. typical 1.15V bridges, lowering thermal stress on PCB layout. |
| RoHS-compliant & cleanable | Compatible with Freon, alcohol, and chlorothene solvents-supports post-assembly cleaning in high-reliability manufacturing. |
Applications
| Industrial Motor Drives | LED Streetlight Power Supplies |
|---|---|
Use Scenario: Rectifying 230VAC mains to DC bus for 3-phase inverter stages in HVAC blowers and conveyor drives. IC Role / Device Role / Timing Role: Bridge rectifier providing unregulated DC input to IGBT gate drivers and PWM controllers. Use Value: 600V VRRM ensures margin over 230VAC × √2 (325V), while 250A IFSM handles motor stall surges without fuse coordination issues. | Use Scenario: Converting 277VAC line voltage to DC for constant-current LED driver ICs in outdoor luminaires. IC Role / Device Role / Timing Role: Primary AC/DC interface component delivering stable DC bus to buck or flyback controller ICs. Use Value: UL 94V-0 housing and 4.7°C/W RJC enable compact, sealed enclosure designs meeting Class P and IP67 thermal/safety standards. |
| Appliance Control Boards | Industrial PLC Power Modules |

IC Role / Device Role / Timing Role: Off-line rectifier feeding linear or switching regulators powering logic and isolation circuitry. Use Value: Low 1.0V VF minimizes heat generation near sensitive analog components, reducing thermal crosstalk in dense control board layouts. | Use Scenario: Providing main DC bus for isolated DC/DC converters powering field I/O modules in programmable logic controllers. IC Role / Device Role / Timing Role: High-reliability bridge rectifier in redundant power entry modules requiring long-term stability under cyclic load.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU606 | Same 600V VRRM and 6.0A I(AV), but GBU package (larger footprint, higher RJC = 5.0°C/W). | Requires larger PCB area and slightly more thermal margin; preferred where legacy GBU footprint compatibility is required. | Select GBU606 only if board layout rework is impractical and thermal headroom ≥0.3°C/W exists. |
| W10M | 1000V VRRM, same 6.0A I(AV), but lower surge rating (170A) and higher VF (1.05V @ 3.0A). | Suitable for higher-voltage universal-input designs (e.g., 230/400VAC systems), but less robust for 250A surge events. | Choose W10M when system-level overvoltage protection exceeds 600V and surge immunity is managed externally. |
Compared with RS605, GBU606 trades thermal efficiency for footprint compatibility, while W10M sacrifices surge margin and conduction loss for higher voltage headroom-neither is pin-compatible, and both require layout validation.

FAQ
What is the maximum allowable case temperature for continuous 6.0A operation?
The RS605 delivers 6.0A average forward current only when the case temperature (TC) is maintained at exactly 100°C, as defined in the derating curve (Fig. 1). Exceeding this temperature requires linear derating; at TC = 125°C, maximum I(AV) drops to approximately 4.2A.
Can RS605 be used with capacitive input filters without derating?
No-datasheet explicitly mandates 20% current derating for capacitive loads due to higher peak currents and increased thermal stress. For example, 6.0A-rated operation becomes 4.8A maximum when feeding a bulk electrolytic capacitor directly after rectification.
Is RS605 lead-free and RoHS compliant?
Yes, RS605 meets RoHS Directive 2011/65/EU requirements. Its terminals are lead-free solderable per MIL-STD-202, Method 208, and the molded plastic body carries UL 94V-0 flammability recognition.
Why does the datasheet state "NOT RECOMMENDED FOR NEW DESIGNS"?
This notice reflects Diodes Incorporated's recommendation to adopt the newer GBU6005–GBU610 series, which offer improved thermal resistance, tighter VF matching, and enhanced surge robustness. RS605 remains fully qualified and supported for existing designs and legacy replacements.
