Product details
Overview
RS2J from Taiwan Semiconductor is a 2 A, 600 V fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 250 ns reverse recovery time, 1.3 V max forward voltage at 2 A, and 5 µA max reverse leakage at 25°C. It serves as primary-side AC/DC rectification in compact switching power supplies.
For engineers reviewing the RS2J datasheet, RS2J pinout, RS2J application, or RS2J equivalent, key selection criteria include repetitive peak reverse voltage (600 V), thermal resistance (RθJA = 55 °C/W), junction temperature range (–55 to +175 °C), and DO-214AA mechanical compatibility with automated SMT assembly.
Technical Context
The RS2J operates as a single-die, unidirectional silicon rectifier with glass-passivated junction for reliability under thermal cycling. Its fast recovery (250 ns) enables high-frequency operation in SMPS topologies up to several hundred kHz while limiting switching losses.
Designed for surface-mount use, the device uses matte tin-plated leads compliant with J-STD-002 solderability and meets JESD201 Class 2 whisker resistance. Polarity is marked by cathode band; moisture sensitivity level is J-STD-020 Level 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse blocking voltage before breakdown; defines safe operating margin in 400 VAC input rectification |
| IF | 2 A - continuous average forward current at TA = 75°C; determines heatsink-free operation in low-power adapters |
| trr | 250 ns - reverse recovery time at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables efficient operation in 200–500 kHz SMPS designs |
| VF (max) | 1.3 V @ 2 A, 25°C - forward voltage drop directly impacts conduction loss and thermal rise in high-duty-cycle applications |
| RθJA | 55 °C/W - junction-to-ambient thermal resistance on standard FR-4 PCB (1 in² copper pad); sets thermal derating envelope |
| IFSM | 50 A - non-repetitive surge current rating (8.3 ms half-sine); supports cold-start inrush handling without failure |
| TJ (max) | +175 °C - maximum junction temperature; allows operation in sealed, high-ambient industrial enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06 | Same VRRM (600 V), identical DO-214AA package, but trr = 150 ns (faster), VF = 1.25 V (lower) | Better suited for >300 kHz operation where lower switching loss is critical | Select STTH2R06 when optimizing for ultra-high-frequency SMPS with tight thermal constraints |
| ES2J | Same VRRM (600 V), same DO-214AA package, but trr = 35 ns (ultrafast), VF = 1.7 V (higher) | Preferred in resonant LLC converters requiring minimal reverse recovery charge | Choose ES2J only if circuit demands sub-50 ns recovery; accept higher conduction loss penalty |
Compared with STTH2R06 and ES2J, the RS2J delivers balanced trade-off between recovery speed (250 ns), forward loss (1.3 V), and cost-making it optimal for mainstream 65–150 kHz AC/DC adapters where thermal margin and manufacturability are prioritized over extreme frequency scaling.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the RS2J?
The RS2J has a VRRM rating of 600 V, verified per Taiwan Semiconductor's L2304 datasheet. This value defines the highest instantaneous reverse voltage the device can block repeatedly without breakdown. It ensures safe operation in universal-input (85–265 VAC) power supplies where peak rectified voltage reaches ~375 VDC, providing essential design margin against transients and line surges.
Does the RS2J have a specified reverse recovery time (trr)?
Yes, the RS2J has a maximum reverse recovery time of 250 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as confirmed in the official TSC datasheet. This parameter is critical for minimizing switching losses in high-frequency SMPS designs and distinguishes RS2J from standard recovery rectifiers with trr > 1 µs.
What package type does the RS2J use, and is it compatible with automated assembly?
The RS2J uses the DO-214AA (SMB) surface-mount package, with matte tin-plated leads certified solderable per J-STD-002. Its standardized footprint, J-STD-020 Level 1 moisture sensitivity, and polarity marking via cathode band make it fully compatible with high-speed pick-and-place equipment and reflow soldering processes used in volume electronics manufacturing.
What is the forward voltage (VF) specification for the RS2J at rated current?
The RS2J exhibits a maximum forward voltage of 1.3 V at IF = 2 A and TJ = 25°C, per the TSC L2304 datasheet. This value directly determines conduction loss (Pcond = VF × IF) and influences thermal design-e.g., at 2 A DC, conduction loss is ≤2.6 W, requiring appropriate PCB copper area for thermal dissipation.
Is the RS2J RoHS compliant and halogen-free?
Yes, the RS2J is both RoHS compliant and halogen-free, as explicitly stated in the TSC product documentation. These attributes meet EU Directive 2011/65/EU and IPC-4101D requirements, ensuring environmental compliance for export to global markets and supporting safer end-of-life recycling without release of toxic halogenated gases during PCB disposal.
