Taiwan Semiconductor Corporation RS2JA

Overview

RS2JA from Taiwan Semiconductor is a 1.5A, 600V fast recovery surface-mount rectifier diode in DO-214AC (SMA) package, featuring 250 ns reverse recovery time, 1.3 V max forward voltage at 1.5 A, and 5 µA max reverse leakage at 25°C - used in DC-DC converters and snubber circuits.

For engineers reviewing the RS2JA datasheet, RS2JA pinout, RS2JA application, or RS2JA equivalent, key selection criteria include its 600 V repetitive peak reverse voltage, 50 A surge rating, 175°C junction temperature capability, thermal resistance of 18°C/W (junction-to-lead), and RoHS/halogen-free compliance for industrial power conversion designs.

Technical Context

The RS2JA operates as a single-die, unidirectional fast recovery rectifier with glass-passivated junction for enhanced reliability. Its 250 ns trr enables high-frequency switching in SMPS topologies, while the DO-214AC (SMA) package supports automated placement and meets J-STD-020 moisture sensitivity level 1.

Thermal performance is defined by R_θJL = 18°C/W and R_θJA = 55°C/W, enabling sustained 1.5 A conduction at elevated ambient temperatures. Reverse leakage remains ≤200 µA at 125°C, supporting stable operation in thermally demanding lighting and converter applications.

Supply support for RS2JA includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, serving global power electronics and industrial markets since 1979.

The RS2x series was designed specifically for high-reliability, medium-current rectification in space-constrained surface-mount power supplies - emphasizing thermal resilience, automated assembly compatibility, and consistent parametric performance across voltage grades.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for RS2JA?

The RS2JA has a V_RRM of 600 V, meaning it can reliably block up to 600 V of reverse voltage in repetitive operation. This value is confirmed in the Absolute Maximum Ratings table on page 2 of the official Taiwan Semiconductor datasheet (Version I2304). Exceeding this voltage risks avalanche breakdown and permanent device failure. The RS2JA is therefore suited for 400 V DC bus applications with ≥50% safety margin.

What is the reverse recovery time (t_rr) specification for RS2JA?

The RS2JA has a reverse recovery time (t_rr) of 250 ns, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This value is explicitly listed in the Electrical Specifications table on page 2 of the Taiwan Semiconductor datasheet. It distinguishes RS2JA from lower-voltage variants like RS2AA (150 ns) and higher-voltage RS2KA (500 ns), confirming its optimized trade-off between speed and voltage rating.

Is RS2JA RoHS and halogen-free compliant?

Yes, RS2JA is both RoHS compliant and halogen-free, as stated in the FEATURES section of the Taiwan Semiconductor datasheet (Version I2304). The device uses lead-free matte tin plating on leads and halogen-free molding compound meeting IEC 61249-2-21 requirements. This compliance is verified through material declarations and third-party testing reports available upon request from Aetrix Electronics.

What package type does RS2JA use, and what are its key mechanical attributes?

RS2JA uses the DO-214AC (SMA) surface-mount package. Key mechanical attributes include UL 94V-0 flammability-rated molding compound, J-STD-002 solderable matte tin-plated leads, JESD201 Class 2 whisker resistance, and polarity indicated by a visible cathode band. The package weight is approximately 0.060 g, and dimensions conform to JEDEC DO-214AC standards per drawing HQ2SD07-DO214SMC-034 REV A.

Can RS2JA replace RS2GA or RS2KA in an existing design?

RS2JA is not a direct replacement for RS2GA (400 V) or RS2KA (800 V) without circuit review. While all share the same DO-214AC package and 1.5 A rating, their V_RRM and t_rr differ: RS2GA is rated for 400 V with 250 ns t_rr, RS2KA for 800 V with 500 ns t_rr. Substituting RS2JA into a 400 V design may over-specify voltage margin; using it in an 800 V design violates V_RRM limits. Always verify system-level voltage stress before interchange.
