Product details
Overview
RS2DA-13 from Diodes Incorporated is a 200 V, 1.5 A surface-mount fast recovery rectifier in SMA package with 150 ns reverse recovery time, 1.3 V forward voltage at 1.5 A, and 50 A non-repetitive surge rating - used in AC/DC input stage of compact offline power supplies.
For engineers reviewing the RS2DA-13 datasheet, RS2DA-13 pinout, RS2DA-13 application, or RS2DA-13 equivalent, key selection criteria include VRRM derating for capacitive loads, thermal resistance (20 K/W) under PCB copper pad heatsinking, and trr-driven switching loss in 65–135 kHz flyback converters.
Technical Context
This device employs glass-passivated silicon die to achieve fast recovery (trr = 150 ns) with low Qrr, enabling high-frequency operation while maintaining low conduction loss. Its 1.3 V VFM at 1.5 A and 20 K/W junction-to-terminal thermal resistance support thermally constrained SMT layouts.
The SMA package features solderable terminals compliant with MIL-STD-202 Method 208, UL 94V-0 molded plastic case, and cathode band polarity marking - optimized for reflow-compatible automated assembly without lead bending or mechanical stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - blocks up to 200 V repetitive reverse voltage, suitable for 115 VAC input with safety margin. |
| IO @ TT=120°C | 1.5 A - average rectified current rating at terminal temperature of 120°C, defines continuous DC output capability. |
| trr | 150 ns - reverse recovery time measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; limits switching loss in high-frequency SMPS. |
| VFM @ IF=1.5A | 1.3 V - forward voltage drop determines conduction loss and thermal dissipation in rectifier leg. |
| IFSM | 50 A - non-repetitive peak surge current (8.3 ms half-sine), supports cold-start inrush tolerance. |
| RJT | 20 K/W - junction-to-terminal thermal resistance with 5.0 mm² × 0.013 mm Cu pad; enables thermal design without external heatsink. |
Pinout & Package
SMA package: molded plastic case, cathode indicated by band on body, anode and cathode terminals aligned for standard SMT placement; weight ≈ 0.065 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | AC input connection point | Accepts alternating input; must withstand full reverse voltage during negative half-cycle. |
| Cathode | DC output connection point | Delivers rectified unidirectional current; polarity marked by visible band on package body. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die | Enables stable trr and IR performance across -65°C to +150°C operating range without passivation degradation. |
| Fast recovery (150 ns) | Reduces switching losses in 65–135 kHz flyback and forward converters versus standard rectifiers. |
| UL 94V-0 plastic case | Meets flammability requirements for enclosed power adapters and industrial control enclosures. |
| 5.0 mm² copper pad thermal path | Allows direct PCB heat spreading without thermal vias or metal-core substrates in space-constrained designs. |
Applications
| AC/DC Adapter Input Stage | Industrial PLC Power Supply |
|---|---|
Use Scenario: 115 VAC input rectification in wall-wart adapters with <15 W output and no PFC stage. IC Role / Device Role / Timing Role: Primary-side uncontrolled rectifier converting AC line to bulk DC before buck/flyback regulation. Use Value: 150 ns trr minimizes diode turn-off loss at 100 kHz switching, improving efficiency over 500 ns alternatives. | Use Scenario: Input rectification in DIN-rail mounted 24 VDC PLC power modules with wide ambient (-25°C to +70°C). IC Role / Device Role / Timing Role: High-reliability bridge input diode handling 1.5 A continuous load with 50 A surge immunity. Use Value: Glass passivation ensures long-term IR stability under thermal cycling and humidity exposure per IEC 61000-6-2. |
| LED Driver Bulk Rectification | Medical Equipment Auxiliary Supply |
Use Scenario: Off-line LED driver with passive PFC and constant-current output for commercial lighting. IC Role / Device Role / Timing Role: Fast-recovery rectifier in voltage-doubler or single-phase bridge feeding HV DC bus. Use Value: Low VFM (1.3 V) reduces conduction loss at 1.5 A, lowering thermal stress on FR4 PCB traces. | Use Scenario: Isolated auxiliary supply (<5 W) powering microcontroller and sensors in Class II medical devices. IC Role / Device Role / Timing Role: Safety-isolated primary-side rectifier meeting creepage/clearance and flammability (UL 94V-0) requirements. Use Value: UL-certified package and -65°C to +150°C rating support compliance with IEC 60601-1 3rd edition environmental testing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR120 | VRRM = 200 V, trr = 75 ns, IO = 1 A, SMA package | Lower current rating (1 A vs. 1.5 A); requires parallel use for same output power | Select when faster recovery is critical and load current ≤1 A. |
| Vishay VS-1N5819HM3/85A | VRRM = 40 V, IF = 1 A, trr ≈ 40 ns, SMA package | Not rated for 115 VAC input; limited to low-voltage DC-DC front-end or OR-ing | Only suitable for ≤40 V systems; not a functional replacement for RS2DA-13. |
Compared with MUR120 and VS-1N5819HM3/85A, RS2DA-13 uniquely balances 1.5 A current, 200 V blocking, and 150 ns trr in SMA - making it optimal for cost-sensitive, thermally constrained 115 VAC input stages where 1 A alternatives require derating or paralleling.

FAQ
What is the maximum allowable PCB copper pad area for thermal optimization of RS2DA-13?
The datasheet specifies 5.0 mm² of 0.013 mm thick copper pad per terminal as the reference condition for RJT = 20 K/W. Larger pads improve thermal performance but do not change the rated IO unless validated per JEDEC JESD51-2. No minimum pad size is defined, but 2.5 mm² is typical for reliability in reflow profiles.
Can RS2DA-13 be used in a full-wave bridge configuration?
Yes - RS2DA-13 is a single die rectifier with isolated anode/cathode terminals and is commonly used in discrete full-wave bridges. Four units can form a 200 V, 1.5 A bridge; ensure matching VFM and trr across all four devices to avoid current imbalance and localized heating.
Is RS2DA-13 compliant with lead-free reflow standards?
Yes - its terminals are solder-plated and qualified per MIL-STD-202, Method 208. It supports standard Pb-free reflow profiles (peak 260°C, 10 sec max), and the UL 94V-0 package remains dimensionally stable without warping or delamination.
How does capacitive load affect RS2DA-13 current rating?
The datasheet mandates 20% derating of IO for capacitive loads due to higher peak currents. At TA = 25°C, the 1.5 A rating drops to 1.2 A - this reflects increased RMS current stress and potential thermal runaway if not accounted for in transformer and capacitor sizing.
