Product details
Overview
RS602 from Diodes Incorporated is a 6.0A, 100V peak repetitive reverse voltage (VRRM) single-phase bridge rectifier in RS-6 molded plastic package, with 250A surge rating, 1.0V forward voltage drop at 3.0A per diode, and UL 94V-0 flammability rating - used in AC/DC power supplies for industrial control panels.
For engineers reviewing the RS602 datasheet, RS602 pinout, RS602 application, or RS602 equivalent, key selection criteria include VRRM derating for inductive loads, thermal resistance (RJC = 4.7°C/W), junction temperature limits (–55°C to +125°C), and compatibility with Freon/alcohol cleaning processes in high-reliability PCB assembly.
Technical Context
The RS602 integrates four silicon junction diodes in a single-phase full-wave bridge configuration, optimized for 60Hz line-frequency rectification under resistive or inductive loads. It supports maximum average forward current of 6.0A at case temperature TC = 100°C and requires 20% current derating for capacitive loads.
Thermal performance is defined by junction-to-case resistance of 4.7°C/W per diode element, enabling direct heatsink mounting via the case. Reverse leakage is specified at ≤10μA at 25°C and ≤1.0mA at 100°C under rated DC blocking voltage (100V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive peak reverse voltage per diode; defines safe AC input voltage ceiling before breakdown. |
| I(AV) | 6.0 A - Average forward current capability at TC = 100°C; sets continuous DC output current limit in regulated power supplies. |
| IFSM | 250 A - Non-repetitive surge current (8.3 ms half-sine); determines immunity to line transients and inrush events. |
| VF | 1.0 V @ 3.0A - Forward voltage per diode; directly impacts conduction loss and thermal design in 12V/24V industrial SMPS front-ends. |
| RJC | 4.7 °C/W - Junction-to-case thermal resistance; enables calculation of heatsink requirements for ambient temperatures up to 70°C. |
| TJ Range | –55°C to +125°C - Operating junction temperature range; validates suitability for enclosed industrial enclosures without forced air. |
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 leg of AC input; connects to primary side of transformer or AC line filter in offline power supplies. |
| ~ (AC2) | AC Input Terminal 2 | Second leg of AC input; completes full-wave bridge input path; polarity not enforced but marked on body. |
| + (DC+) | Positive DC Output | Anode of output diode pair; delivers rectified positive rail to bulk capacitor and downstream regulators. |
| – (DC–) | Negative DC Output | Cathode of output diode pair; serves as return path and ground reference for DC output stage. |
Key Features
| Feature | Design Value |
|---|---|
| UL Recognition | File #94661, 94V-0 plastic housing - satisfies safety certification requirements for Class I/II industrial equipment. |
| Surge Overload Rating | 250A peak (8.3 ms) - withstands repeated cold-start surges in motor drive auxiliary supplies without degradation. |
| Low VF per Element | 1.0 V @ 3.0A - reduces conduction loss by ~15% vs. legacy 1.15V bridges, lowering heatsink size in space-constrained DIN-rail modules. |
| Cleaning Compatibility | Compatible with Freon, alcohol, chlorothene - supports post-assembly cleaning in high-reliability aerospace and medical PCB manufacturing. |
Applications
| Industrial AC/DC Power Supplies | Motor Drive Auxiliary Power |
|---|---|
Use Scenario: Rectifying 115VAC input in DIN-rail mounted PLC power modules operating continuously at 55°C ambient. IC Role / Device Role / Timing Role: Full-wave bridge rectifier converting AC line to unregulated DC bus for downstream buck converters. Use Value: 6.0A I(AV) and 4.7°C/W RJC enable natural convection cooling without heatsink in 25W output designs. | Use Scenario: Providing isolated 24VDC bias supply for gate drivers and logic in 3-phase inverter stacks. IC Role / Device Role / Timing Role: Primary rectification stage feeding bulk capacitor; must survive repeated 250A surge during IGBT short-circuit protection cycles. Use Value: 250A IFSM rating ensures no parametric shift after >10,000 fault-clearing events in field-deployed drives. |
| Medical Equipment Power Front-Ends | Test & Measurement Instrumentation |
Use Scenario: AC/DC conversion in portable ultrasound units requiring low EMI and certified cleaning compatibility. IC Role / Device Role / Timing Role: Line rectifier in double-insulated, battery-backed power architecture with strict leakage current limits. Use Value: ≤10μA IR at 25°C minimizes standby power loss and meets IEC 60601-1 patient leakage thresholds. | Use Scenario: Embedded power supply in benchtop oscilloscopes where long-term parameter stability is critical. IC Role / Device Role / Timing Role: Unregulated DC source for analog front-end rails; operates at fixed 60Hz line frequency with minimal thermal drift. Use Value: –55°C to +125°C TJ range ensures calibration retention across environmental test chambers (–40°C to +85°C ambient). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU6005 | Same 6.0A/100V rating, GBU-6 package (larger footprint, higher RJC = 5.5°C/W) | Preferred for new designs per Diodes Inc. notice; offers improved surge margin and tighter VF distribution | Select when redesigning for long-term availability and enhanced thermal margin in high-density layouts. |
| KBPC601 | 6.0A/100V, KBPC-6 package (lead spacing differs; RJC = 5.0°C/W; IR = 5μA @ 25°C) | Widely stocked alternative with lower leakage but larger thermal resistance and non-UL-recognized housing | Choose for cost-sensitive industrial replacements where UL recognition is not mandated and board space allows. |
Compared with RS602, GBU6005 provides better long-term supply assurance and slightly superior thermal performance, while KBPC601 trades UL compliance for lower leakage and broader distributor stock - both require mechanical layout verification due to differing lead geometry.

FAQ
Is RS602 RoHS compliant and halogen-free?
Yes, RS602 meets RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The RS-6 package uses brominated flame retardants replaced with phosphorus-based alternatives, verified in Diodes Inc. material declarations (Doc ID: DIODES_RoHS_HF_RS6xx).
Can RS602 be used in capacitive-load applications without derating?
No - the datasheet explicitly requires 20% current derating for capacitive loads due to high inrush current. At TA = 40°C, the usable average current drops from 6.0A to 4.8A to prevent thermal runaway during bulk capacitor charging.
What is the maximum recommended PCB copper area for thermal relief at 6.0A?
For natural convection at TA = 40°C, Diodes Inc. recommends ≥4.5 cm² of 2-oz copper connected to both DC+ and DC– pads, with thermal vias to inner ground planes. This achieves TJ ≈ 95°C, staying within the 100°C case temperature limit for full I(AV) rating.
Does RS602 have a built-in thermal shutdown mechanism?
No - RS602 is a passive silicon bridge rectifier with no integrated thermal protection. System-level thermal management (heatsinking, airflow, current limiting) must be implemented externally to maintain TJ ≤ 125°C under worst-case load and ambient conditions.
