Product details

Overview

RS2D-T from Taiwan Semiconductor is a 2A, 200V fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 150 ns reverse recovery time, 1.11 V forward voltage at 2A/25°C, and 50 A surge current capability. It serves as a primary AC/DC input rectifier in compact switching power supplies.

For engineers reviewing the RS2D-T datasheet, RS2D-T pinout, RS2D-T application, or RS2D-T equivalent, key selection criteria include its 200V V_RRM, low 1.11 V V_F at rated current, 150 ns t_rr, thermal resistance of 78 °C/W (junction-to-ambient), and compatibility with automated SMT placement on standard PCBs.

Technical Context

The RS2D-T employs a single-die, glass-passivated PN junction optimized for fast recovery (t_rr ≤ 150 ns) and low conduction loss. Its 200V V_RRM rating targets mid-voltage DC/DC front-end stages where efficiency and thermal management are critical.

Designed for surface-mount operation on 10 mm × 10 mm copper pads, it delivers R_θJA = 78 °C/W and R_θJL = 20 °C/W, enabling reliable 2A continuous operation up to +150°C junction temperature with minimal heatsinking.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - Maximum repetitive reverse voltage before breakdown; defines safe operating range in 115/230 VAC input rectification.
I_F	2 A - Continuous forward current rating; supports sustained load in compact 10–30 W SMPS designs.
t_rr	≤150 ns - Fast reverse recovery time; minimizes switching losses in 50–500 kHz converters.
V_F @ 2A, 25°C	1.11 V - Forward voltage drop; determines conduction loss (2.22 W at full load) and thermal rise.
I_FSM	50 A - Non-repetitive surge current (8.3 ms); withstands inrush and transient overloads without failure.
R_θJA	78 °C/W - Junction-to-ambient thermal resistance on standard test board; enables thermal design without forced air or heatsink below ~1.5 W dissipation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar fast recovery rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R02	Same 2A/200V rating; t_rr = 35 ns (faster), V_F = 1.15 V @ 2A, R_θJA = 65 °C/W	Better suited for higher-frequency (>1 MHz) topologies requiring ultra-fast recovery	Select STTH2R02 when minimizing switching loss dominates over conduction loss and thermal margin is constrained.
ES2D	Same DO-214AA package; V_RRM = 200 V, t_rr = 35 ns, V_F = 1.15 V @ 2A, I_FSM = 60 A	Higher surge rating and faster recovery, but tighter V_F tolerance (±5%) vs. RS2D-T's typical value	Choose ES2D for enhanced surge immunity in harsh-input environments where layout space matches SMB footprint.

Compared with STTH2R02 and ES2D, the RS2D-T offers a balanced trade-off of cost, thermal performance (78 °C/W), and proven reliability in mainstream 50–300 kHz SMPS, making it optimal for cost-sensitive industrial and consumer power supplies where 150 ns t_rr suffices.

FAQ

What is the maximum junction temperature rating for the RS2D-T?

The RS2D-T has a maximum junction temperature (T_JMAX) of +150°C, verified per absolute maximum ratings in the official datasheet. This allows continuous 2A operation in ambient temperatures up to +80°C when mounted on a 10 mm × 10 mm Cu pad, given its R_θJA of 78 °C/W. Derating curves confirm usable current down to zero at 150°C junction.

Does the RS2D-T have a cathode marking, and how is polarity identified?

Yes, the RS2D-T uses a visible cathode band on the DO-214AA (SMB) package body to indicate polarity. The banded end corresponds to the cathode terminal, consistent with industry-standard diode marking conventions. This band is clearly shown in the official package outline drawing and marking diagram in the RS2D-T datasheet revision C2102.

What is the reverse recovery time (t_rr) specification for the RS2D-T, and under what test conditions?

The RS2D-T has a maximum reverse recovery time (t_rr) of 150 ns, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_RR = 0.25 A, per the electrical specifications table in the official datasheet. This value applies specifically to the RS2D-T variant and is slower than RS2J-T (250 ns) and RS2K-T/RS2M-T (500 ns), reflecting its optimized speed-voltage trade-off.

Is the RS2D-T compliant with RoHS and halogen-free standards?

Yes, the RS2D-T is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the official datasheet. The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated to J-STD-002 standards - all confirmed in version C2102 documentation.

What is the surge current rating (I_FSM) for the RS2D-T, and how does it compare across pulse durations?

The RS2D-T supports 50 A non-repetitive surge current (I_FSM) for an 8.3 ms half-sine wave, and 128 A for a 1.0 ms pulse, both at T_A = 25°C. These values are fixed per the Absolute Maximum Ratings table and apply identically across the RS2x-T family - confirming robust inrush handling in offline power supplies without external fusing.
