Product details
Overview
HS2M-T from Taiwan Semiconductor is a 1000 V repetitive peak reverse voltage, 2 A average forward current surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring 1.31 V typical forward voltage at 2 A and 25°C, 75 ns maximum reverse recovery time, and glass passivated junction for low leakage and high reliability in switching power supplies.
For engineers reviewing the HS2M-T datasheet, HS2M-T pinout, HS2M-T application, or HS2M-T equivalent, key selection criteria include its 1000 V VRRM, 50 A IFSM surge rating, 150°C maximum junction temperature, and DO-214AA mechanical compatibility with automated SMT assembly lines.
Technical Context
This is a single-die, standard recovery silicon rectifier optimized for high-voltage DC/DC conversion and freewheeling roles where fast recovery (≤75 ns), low thermal resistance (RθJL = 20°C/W), and stable reverse leakage (<350 µA at 125°C) are required.
It operates across –55°C to +150°C junction temperature range, uses matte tin-plated leads compliant with J-STD-002 solderability, and meets JESD201 Class 1 whisker resistance and UL 94V-0 flammability standards in its molded SMB package.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06DJF | 600 V VRRM, 2 A, 60 ns trr, TO-277 package | Limited to ≤600 V systems; lower surge rating (40 A) | Select only if system VRRM requirement is ≤600 V and faster recovery is prioritized over voltage headroom |

FAQ
What is the maximum repetitive peak reverse voltage rating for HS2M-T?
The HS2M-T has a maximum repetitive peak reverse voltage (VRRM) of 1000 V, verified per TSC datasheet C2102. This rating applies under standard test conditions (TA = 25°C) and defines the highest reverse-biased voltage the device can block repeatedly without breakdown. It is the defining parameter distinguishing HS2M-T from lower-voltage variants like HS2K-T (800 V) and HS2J-T (600 V).
Does HS2M-T have a specified reverse recovery time, and how is it measured?
Yes, HS2M-T has a maximum reverse recovery time (trr) of 75 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the TSC C2102 datasheet. This value applies to all HS2J-T through HS2M-T variants and reflects performance in hard-switched converter topologies operating up to 500 kHz, directly impacting switching loss and EMI generation.
Is HS2M-T compatible with lead-free reflow soldering processes?
Yes, HS2M-T features matte tin-plated leads qualified to J-STD-002 for solderability and is rated for lead-free reflow profiles. Its DO-214AA (SMB) package is moisture sensitivity level 1 (per J-STD-020), meaning it may be stored indefinitely at ambient conditions and requires no pre-bake prior to standard Pb-free reflow, supporting high-yield automated assembly.
What is the thermal resistance from junction to lead (RθJL) for HS2M-T, and how is it validated?
The junction-to-lead thermal resistance (RθJL) of HS2M-T is 20°C/W, measured on a standardized 10 mm × 10 mm copper pad PCB per JEDEC JESD51-14. This value enables accurate thermal modeling of conduction losses at 2 A, confirming that the device remains within its 150°C TJMAX limit without heatsinking under typical industrial ambient conditions.
How does the forward voltage of HS2M-T vary with temperature and current?
At 2 A and 25°C, HS2M-T exhibits 1.31 V typical forward voltage (VF); this drops to 1.07 V at 125°C due to semiconductor physics. The datasheet specifies 1.70 V maximum at 25°C and 1.49 V maximum at 125°C. These values define worst-case conduction loss budgets for thermal design and efficiency calculations in real-world operating conditions.
