Product details
Overview
RS2JA-T from Taiwan Semiconductor is a 600V, 2A fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 250 ns reverse recovery time, 1.12 V forward voltage at 2A/25°C, and 100 µA max reverse leakage at 125°C - deployed in DC-DC converters and switching inverters.
For engineers reviewing the RS2JA-T datasheet, RS2JA-T pinout, RS2JA-T application, or RS2JA-T equivalent, key selection criteria include VRRM=600V, trr=250 ns, VF=1.12 V @ 2A, thermal resistance RθJA=86°C/W, and DO-214AC mechanical compatibility with automated SMT assembly.
Technical Context
The RS2JA-T employs a glass-passivated single-die silicon junction optimized for fast switching in high-frequency power conversion. Its 600V VRRM rating and 250 ns trr enable efficient operation in 50–500 kHz SMPS topologies without excessive switching loss.
Thermal performance is defined by RθJL=14°C/W and RθJA=86°C/W on a 5 mm × 5 mm Cu pad PCB, supporting continuous 2A conduction up to TJ=150°C with adequate heatsinking. Reverse leakage remains ≤100 µA at full-rated junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse voltage the device blocks reliably in circuit |
| IF | 2 A - average forward current rating under specified thermal conditions |
| trr | 250 ns - reverse recovery time defining minimum dead-time requirements in bridge configurations |
| VF @ 2A, 25°C | 1.12 V - forward voltage drop determining conduction loss and thermal load at rated current |
| IR @ 125°C | 100 µA - reverse leakage current impacting standby power and high-impedance sensing accuracy |
| RθJA | 86 °C/W - junction-to-ambient thermal resistance on standard 5 mm × 5 mm PCB copper pad |
Pinout & Package
DO-214AC (SMA) surface-mount package with cathode-indicated band; matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 1 whisker resistance.

Applications
| AC-DC Front-End Rectification | DC-DC Converter Output Stage |
|---|---|
Use Scenario: Converts 100–240 VAC mains to bulk DC in offline SMPS with PFC stage. IC Role / Device Role / Timing Role: Single-phase bridge leg diode handling 2A average output current at 600V blocking. Use Value: 250 ns trr minimizes reverse recovery charge (Qrr), reducing MOSFET turn-on loss and snubber stress. | Use Scenario: Freewheeling diode in synchronous buck converter delivering 5–12 V at 2A to microcontroller or FPGA rails. IC Role / Device Role / Timing Role: Standby path for inductor current when high-side switch is off; operates at 200–500 kHz. Use Value: 1.12 V VF at 2A limits conduction loss to <2.24 W, easing thermal design on compact PCBs. |
| Switching Inverter Auxiliary Supply | Industrial Sensor Power Conditioning |
Use Scenario: Generates isolated 15 V bias supply for gate drivers in 3-phase motor inverters. IC Role / Device Role / Timing Role: Secondary-side rectifier on flyback transformer; sees discontinuous conduction mode pulses. Use Value: Low IR (≤5 µA @ 25°C) prevents capacitor discharge drift, maintaining stable auxiliary rail under light load. | Use Scenario: Input rectification for 24 VDC-powered analog sensor modules in factory automation. IC Role / Device Role / Timing Role: General-purpose protection and polarity correction before LDO regulator input. Use Value: DO-214AC footprint ensures compatibility with legacy layouts; UL 94V-0 molding compound meets industrial flame-safety standards. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06U | VRRM=600V, trr=35 ns, VF=1.15 V @ 2A - faster but higher VF and cost | Better suited for >1 MHz resonant converters where Qrr dominates loss | Select if system operates >500 kHz and thermal margin allows 1.15 V VF penalty |
| ES2J | VRRM=600V, trr=35 ns, VF=0.95 V @ 2A - lower VF but non-glass-passivated junction | Higher risk of parametric shift in humid/harsh environments | Prefer for cost-sensitive consumer designs with controlled ambient conditions |
Compared with STTH2R06U and ES2J, the RS2JA-T delivers balanced trade-offs: moderate trr (250 ns) for mid-frequency SMPS, robust glass passivation for industrial reliability, and proven manufacturability in DO-214AC automated lines - making it optimal for 100–300 kHz industrial power supplies requiring long-term stability.
