Product details

Overview

HS1M-K from Taiwan Semiconductor is a 1 A, 1000 V repetitive peak reverse voltage (V_RRM) surface-mount silicon rectifier diode in DO-214AC (SMA) package, featuring 1.7 V max forward voltage at 1 A and 75 ns reverse recovery time, used in high-efficiency DC-DC converters and switching inverters.

For engineers reviewing the HS1M-K datasheet, HS1M-K pinout, HS1M-K application, or HS1M-K equivalent, key selection criteria include its 1000 V V_RRM, 30 A I_FSM, 150 °C maximum junction temperature, moisture sensitivity level 1 compliance, and DO-214AC mechanical compatibility with automated SMT placement.

Technical Context

This device is a single-die, glass-passivated, fast-recovery silicon rectifier optimized for high-voltage switching applications. Its 75 ns reverse recovery time and 15 pF junction capacitance at 1 MHz / 4 V support efficient operation in SMPS topologies up to several hundred kHz.

The HS1M-K operates across -55 °C to +150 °C junction temperature range with 70 °C/W junction-to-ambient thermal resistance. Its matte tin-plated leads meet J-STD-002 solderability and JESD 201 Class 1A whisker requirements, ensuring robust reflow reliability.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) of the HS1M-K?

The HS1M-K has a maximum repetitive peak reverse voltage (V_RRM) of 1000 V, as confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version F2111). This rating defines the highest instantaneous reverse voltage the diode can block repeatedly without breakdown under normal operating conditions, making it suitable for high-voltage AC-DC and DC-DC applications where transient margins exceed 800 V.

Does the HS1M-K have a specified reverse recovery time (t_rr)?

Yes, the HS1M-K 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 explicitly listed in the Electrical Specifications section for HS1J-K through HS1M-K variants. The 75 ns t_rr supports efficient operation in switching frequencies up to 500 kHz while minimizing switching loss and EMI generation in the HS1M-K circuit implementation.

What package type does the HS1M-K use, and is it compatible with standard SMT processes?

The HS1M-K uses the DO-214AC (SMA) surface-mount package, with matte tin-plated leads that meet J-STD-002 solderability requirements. It is rated moisture sensitivity level 1 per J-STD-020, meaning no pre-bake is required before reflow. These features make the HS1M-K fully compatible with standard automated SMT assembly lines, including lead-free reflow profiles, without process modification.

What is the forward voltage (V_F) of the HS1M-K at rated current?

The HS1M-K has a maximum forward voltage (V_F) of 1.7 V at I_F = 1 A and T_J = 25 °C, as specified in the Electrical Specifications table. This value represents the worst-case conduction drop under nominal load, directly determining power dissipation (≤1.7 W) and thermal design requirements for the HS1M-K in continuous operation.

Is the HS1M-K RoHS compliant and halogen-free?

Yes, the HS1M-K is RoHS compliant and halogen-free in accordance with IEC 61249-2-21, as stated in the FEATURES section of the Taiwan Semiconductor datasheet. This dual compliance ensures the HS1M-K meets environmental regulations for sale in the EU, China, and other major markets, and supports safer end-of-life processing without release of toxic halogenated gases during recycling or incineration.
