Product details
Overview
RS3D from Taiwan Semiconductor is a fast recovery surface-mount rectifier diode in DO-214AB (SMC) package, rated for 200 V repetitive peak reverse voltage (VRRM), 3 A average forward current (IF), and 100 A non-repetitive surge current (IFSM), used in DC-DC converters and snubber circuits.
For engineers reviewing the RS3D datasheet, RS3D pinout, RS3D application, or RS3D equivalent, key selection criteria include its 200 V VRRM rating, 150 ns reverse recovery time (trr), 1.3 V max forward voltage at 3 A, 15 °C/W junction-to-lead thermal resistance, and DO-214AB mechanical compatibility with automated SMT assembly.
Technical Context
The RS3D operates as a single-die, unidirectional silicon rectifier with glass-passivated junction for reliability under thermal cycling and humidity exposure. Its fast recovery (trr = 150 ns) enables high-frequency switching in SMPS topologies while maintaining low conduction loss (VF ≤ 1.3 V @ 3 A).
Thermally, it supports operation from –55 °C to +175 °C junction temperature, with RθJL = 15 °C/W enabling efficient heat transfer to PCB copper or heatsink via cathode-anode leads. Moisture sensitivity level is J-STD-020 Level 1 - no bake required before reflow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum repetitive reverse blocking voltage; defines safe operating range in flyback/clamp circuits |
| IF | 3 A - continuous average forward current at TC = 75 °C; sets power handling in DC-DC output stages |
| trr | 150 ns - measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables >100 kHz switching without excessive switching loss |
| VF | ≤1.3 V @ 3 A, 25 °C - forward conduction drop directly impacts efficiency and thermal rise in rectification paths |
| RθJL | 15 °C/W - junction-to-lead thermal resistance; allows direct thermal modeling from die to PCB pad or heatsink interface |
| IFSM | 100 A - 8.3 ms half-sine surge rating; withstands inrush and fault transients in industrial power supplies |
| IR | ≤10 µA @ 200 V, 25 °C - low leakage ensures minimal standby power loss in high-impedance bias networks |

| DC-DC Converter Output Rectification | Snubber Network Diode |
|---|---|
Use Scenario: Used in secondary-side synchronous or freewheeling rectification of isolated DC-DC converters delivering 5–24 V at up to 3 A. IC Role / Device Role / Timing Role: Unidirectional current valve converting transformer AC output to regulated DC; timing role defined by trr < 150 ns to minimize dead-time loss. Use Value: Low VF (≤1.3 V) reduces conduction loss; DO-214AB footprint enables compact layout with thermal relief pads on cathode. | Use Scenario: Placed across MOSFET drain-source or transformer windings to absorb voltage spikes during switching transitions. IC Role / Device Role / Timing Role: Clamp diode conducting only during transient overvoltage events; fast trr ensures rapid turn-on before voltage exceeds VRRM. Use Value: 200 V VRRM provides margin above typical 150 V clamp rails; 100 A IFSM handles multi-cycle surge without degradation. |
| Switching Inverter Freewheeling | LED Driver Input Rectification |
Use Scenario: Freewheeling path in H-bridge or half-bridge inverters driving inductive loads such as BLDC motors or solenoids. IC Role / Device Role / Timing Role: Provides low-loss return path for inductive kickback; trr = 150 ns prevents shoot-through risk during complementary switching. Use Value: High TJ max (175 °C) sustains operation under motor drive thermal stress; RθJL = 15 °C/W supports direct heatsinking via cathode pad. | Use Scenario: Bridge or single-diode input rectification in constant-current LED drivers for commercial lighting fixtures. IC Role / Device Role / Timing Role: Converts AC line or offline DC to unregulated DC bus; operates continuously at IF = 3 A with minimal derating. Use Value: 3 A IF rating matches typical 20–30 W LED driver outputs; halogen-free/ROHS compliance meets lighting safety certifications (UL 1598, IEC 62368). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L02 | VRRM = 200 V, IF = 3 A, trr = 110 ns, VF = 1.15 V typ @ 3 A - faster recovery and lower VF than RS3D | Better suited for >200 kHz designs where Qrr minimization is critical; higher cost and tighter thermal design needed due to smaller SOD-123FL package | Select STTH3L02 when optimizing for ultra-low switching loss in high-density SMPS; verify layout thermal relief for smaller footprint |
| MBR3200 | VRRM = 200 V, IF = 3 A, but Schottky construction - VF = 0.85 V typ @ 3 A, trr not applicable, TJ max = 125 °C | Lower conduction loss but limited to ≤125 °C ambient; unsuitable for high-temp industrial environments where RS3D's 175 °C rating is required | Choose MBR3200 for low-VF, low-noise applications below 125 °C; avoid in motor drives or enclosed enclosures exceeding 85 °C ambient |
Compared with STTH3L02 and MBR3200, the RS3D offers balanced trade-offs: superior thermal robustness (175 °C) vs. Schottky alternatives, and lower cost vs. ultra-fast silicon rectifiers - making it optimal for cost-sensitive, thermally demanding industrial DC-DC and inverter designs.
