Product details

Overview

HS2M from Taiwan Semiconductor is a 2 A, 1000 V repetitive peak reverse voltage (V_RRM) surface-mount fast recovery rectifier in DO-214AA (SMB) package, featuring 1.7 V forward voltage at 2 A and 75 ns reverse recovery time, used in high-efficiency AC/DC converters and industrial SMPS.

For engineers reviewing the HS2M datasheet, HS2M pinout, HS2M application, or HS2M equivalent, key selection criteria include its 1000 V V_RRM, 75 ns trr, 1.7 V V_F at 2 A, junction-to-ambient thermal resistance of 80 °C/W, and DO-214AA mechanical compatibility with automated SMT assembly.

Technical Context

The HS2M employs a single-die, glass-passivated silicon junction optimized for fast switching and low conduction loss in high-voltage DC output stages. Its 1000 V V_RRM rating supports universal-input offline power supplies, while 75 ns reverse recovery time enables operation up to several hundred kHz without excessive switching loss.

Thermal performance is defined by R_θJA = 80 °C/W and T_J(max) = 150 °C, with derating required above 75 °C ambient. The device meets JESD201 Class 2 whisker resistance and UL 94V-0 molding compound requirements for reliability in industrial environments.

FAQ

What is the maximum junction temperature rating for HS2M?

The HS2M has a maximum junction temperature (T_J(max)) of +150 °C, with storage temperature range from –55 °C to +150 °C. This rating allows reliable operation in industrial environments where ambient temperatures reach 70–85 °C, provided thermal design maintains junction temperature below this limit. Derating curves in the HS2M datasheet define allowable I_F versus ambient temperature.

Does HS2M support automated SMT assembly?

Yes, the HS2M uses the DO-214AA (SMB) package with matte tin-plated leads that meet J-STD-002 solderability requirements. Its standardized footprint and cathode band marking enable high-yield, repeatable placement using industry-standard pick-and-place equipment and reflow profiles.

What is the reverse recovery time (t_rr) specification for HS2M?

The HS2M has a reverse recovery time (t_rr) of 75 ns, measured at I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This value is confirmed in the Electrical Specifications table of the official HS2M datasheet and supports efficient operation in high-frequency switch-mode power supplies up to 500 kHz.

How does HS2M compare to HS2J or HS2K in terms of forward voltage?

The HS2M shares the same forward voltage (V_F) specification as HS2J and HS2K: 1.7 V maximum at I_F = 2 A and T_J = 25 °C. All three variants use identical die construction optimized for 600–1000 V V_RRM, resulting in matched conduction characteristics despite differing voltage ratings.

Is HS2M halogen-free and RoHS compliant?

Yes, the HS2M is RoHS compliant and halogen-free in accordance with IEC 61249-2-21. This is explicitly stated in the FEATURES section of the official HS2M datasheet and verified through material declarations from Taiwan Semiconductor, making it suitable for environmentally regulated end equipment.
