Product details

Overview

RS2M from Taiwan Semiconductor is a 2 A, 1000 V fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 500 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 a primary-side output rectifier in high-voltage AC/DC converters for industrial power supplies.

For engineers reviewing the RS2M datasheet, RS2M pinout, RS2M application, or RS2M equivalent, key selection criteria include peak repetitive reverse voltage rating, thermal resistance (R_θJA = 55°C/W), junction temperature range (–55°C to +175°C), and moisture sensitivity level (J-STD-020 Level 1).

Technical Context

The RS2M operates as a single-die, unidirectional fast recovery rectifier with glass-passivated junction and matte tin-plated leads. Its 1000 V V_RRM and 50 A I_FSM support robust surge handling in offline SMPS front-end stages.

Designed for automated placement and reflow soldering, it meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements. Polarity is marked by cathode band; weight is 0.090 g.

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	600 V V_RRM, 350 ns t_rr, TO-220AC package	Limited to ≤400 V_RMS inputs; requires through-hole mounting	Select when lower V_RRM suffices and board space allows larger package
ES2D-E3/57T	200 V V_RRM, 35 ns t_rr, same DO-214AA package	Only suitable for ≤140 V_RMS inputs; faster but lower voltage rating	Choose for low-voltage, ultra-fast recovery needs where 1000 V is unnecessary

Compared with STTH2R06 and ES2D-E3/57T, the RS2M uniquely balances 1000 V blocking capability with SMB-mount compatibility and 500 ns recovery-making it optimal for compact, universal-input, high-voltage SMPS where both ruggedness and surface-mount scalability matter.

FAQ

What is the maximum junction temperature rating for RS2M?

The RS2M has a maximum junction temperature (T_JMAX) of +175°C, enabling reliable operation in enclosed industrial enclosures or high-ambient-temperature environments. This rating is validated per JEDEC test conditions and supports derated operation up to 150°C ambient with appropriate PCB copper area. The RS2M must not exceed this limit during transient or steady-state conditions to ensure long-term reliability.

Does RS2M meet RoHS and halogen-free compliance requirements?

Yes, RS2M is fully RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants, and the matte tin-plated leads are lead-free and compatible with Pb-free reflow profiles. Compliance documentation is available upon request from Taiwan Semiconductor's official product portal.

What is the reverse recovery time (t_rr) specification for RS2M?

The RS2M has a maximum reverse recovery time (t_rr) of 500 ns, measured at I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A per JEDEC test conditions. This value is confirmed in the Electrical Specifications table of the L2304 datasheet revision and applies exclusively to the RS2M variant-not to lower-voltage members of the RS2x family.

Is RS2M suitable for use in automotive applications?

No, RS2M is not qualified for automotive applications. Taiwan Semiconductor explicitly states in its notice that RS2x devices are "not designed for use in medical, life-saving, or life-sustaining applications," and no AEC-Q101 qualification data is published for RS2M. For automotive-grade alternatives, consult TSC's AEC-Q101-certified rectifier portfolio separately.

What packaging and reel quantity is offered for RS2M?

RS2M is supplied in DO-214AA (SMB) package on 3,000-unit tape-and-reel format per ordering code RS2M. The reel complies with EIA-481-D standards, and the device marking includes "RS2M" plus date and factory codes. No bulk or ammo-pack options are listed in the official ordering information.
