Product details

Overview

RS2M-T from Taiwan Semiconductor is a 2A, 1000V fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 500 ns reverse recovery time, 1.03 V forward voltage at 2A/25°C, and 150°C maximum junction temperature. It serves as the high-voltage variant in the RS2x-T series for DC-DC converters and switching inverters requiring robust reverse blocking.

For engineers reviewing the RS2M-T datasheet, RS2M-T pinout, RS2M-T application, or RS2M-T equivalent, key selection criteria include peak reverse voltage rating (1000 V), thermal resistance (R_θJA = 78 °C/W), surge current capability (50 A @ 8.3 ms), and low leakage (<5 µA @ 25°C).

Technical Context

The RS2M-T employs a single-die, glass-passivated PN junction optimized for fast recovery (trr ≤ 500 ns) under 0.5A forward / 1.0A reverse switching conditions. Its 1000 V V_RRM rating enables use in high-input industrial SMPS topologies where voltage margin and transient clamping are critical.

Thermal design is supported by R_θJL = 20 °C/W and R_θJC = 26 °C/W, measured on a 10 mm × 10 mm copper pad PCB. The device meets JESD201 Class 1 whisker resistance and J-STD-020 Level 1 moisture sensitivity requirements.

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 2A/600V rating but lower V_RRM; trr = 35 ns (faster); VF = 1.15 V @ 2A	Not suitable for 1000 V systems; better for <600 V high-frequency flyback	Select when speed > voltage rating; verify layout clearance for lower V_RRM
ES2J	2A/600V; trr = 35 ns; VF = 1.7 V @ 2A; DO-214AA package	Higher VF increases conduction loss; insufficient for 1000 V bus designs	Acceptable only if system V_RRM requirement ≤600 V and thermal headroom exists

Compared with STTH2R06 and ES2J, the RS2M-T uniquely satisfies 1000 V blocking needs in space-constrained SMB layouts while maintaining acceptable recovery speed and thermal performance-making it the only viable option for 800–1000 V DC systems requiring surface-mount rectification.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for RS2M-T?

The RS2M-T has a maximum repetitive peak reverse voltage (V_RRM) of 1000 V, confirmed in the Absolute Maximum Ratings table. This rating allows the RS2M-T to be used in high-voltage DC bus applications such as solar PV string inputs and industrial SMPS front ends where transient overvoltage margins exceed 800 V. The RS2M-T is the highest-voltage member of the RS2x-T family.

Does RS2M-T have a specified reverse recovery time (t_rr)?

Yes, the RS2M-T has a reverse recovery time (t_rr) of ≤500 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is explicitly listed in the Electrical Specifications table for RS2K-T and RS2M-T variants. The 500 ns t_rr balances speed and voltage capability for medium-frequency switching applications.

What is the forward voltage (V_F) of RS2M-T at 2 A and 25°C?

The forward voltage (V_F) of RS2M-T is 1.03 V maximum at 2 A and 25°C, per the Electrical Specifications table. At 125°C, V_F drops to 0.90 V maximum under the same current. These values reflect the device's silicon process optimization for high-temperature conduction efficiency in thermally demanding environments.

Is RS2M-T RoHS and halogen-free compliant?

Yes, RS2M-T is RoHS compliant and halogen-free in accordance with IEC 61249-2-21, as stated in the FEATURES section. The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated per J-STD-002. These compliance attributes make RS2M-T suitable for consumer, industrial, and automotive-qualified power designs.

What is the thermal resistance from junction to ambient (R_θJA) for RS2M-T?

The junction-to-ambient thermal resistance (R_θJA) for RS2M-T is 78 °C/W, measured on a standard 10 mm × 10 mm copper pad PCB per JEDEC test conditions. This value assumes no additional heatsinking and defines the minimum PCB copper area required to maintain T_J ≤ 150°C at full 2 A DC current in still air.
