Product details
Overview
HS2MA-T from Taiwan Semiconductor is a 2 A, 1000 V repetitive peak reverse voltage (VRRM) surface-mount high-efficiency rectifier in DO-214AC (SMA) package, featuring low reverse leakage (≤5 µA at 25°C), 1.40 V max forward voltage at 2 A/25°C, and 75 ns reverse recovery time - deployed in DC-DC converters and switching-mode inverters requiring robust 1 kV blocking capability.
For engineers reviewing the HS2MA-T datasheet, HS2MA-T pinout, HS2MA-T application, or HS2MA-T equivalent, key selection criteria include verified 1000 V VRRM, thermal resistance RθJA = 86 °C/W on 5 mm × 5 mm Cu pad, junction temperature range of –55°C to +150°C, and DO-214AC mechanical compatibility with automated placement systems.
Technical Context
This device is a single-die, glass-passivated silicon PN junction rectifier optimized for high-voltage switching power supplies. Its 1000 V VRRM rating enables use in primary-side rectification where transient overvoltage margins exceed 800 V, and its 75 ns trr supports operation up to several hundred kHz without excessive switching loss.
The HS2MA-T exhibits a forward voltage of 1.40 V maximum at 2 A and 25°C, rising to 1.41 V at 125°C, and maintains ≤100 µA reverse current at 125°C - confirming stable performance across industrial temperature extremes. Junction capacitance is 12 pF at 1 MHz / 4 V, supporting low-noise high-frequency rectification.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06D | 600 V VRRM, 2 A, 60 ns trr, TO-220AC package | Lower voltage rating; requires derating or series stacking for 1000 V applications | Preferred where lower trr and higher surge current (80 A) are prioritized over voltage rating and SMT fit |
| ES2J-M3/5AT | 600 V VRRM, 2 A, 35 ns trr, DO-214AC package | Same footprint but insufficient VRRM; unsuitable for direct replacement in 1000 V circuits | Valid alternative only in designs with ≤600 V bus; offers faster switching and lower VF (1.15 V typ) |
Compared with STTH2R06D and ES2J-M3/5AT, the HS2MA-T uniquely delivers 1000 V VRRM in DO-214AC while maintaining industrial-grade thermal performance (RθJA = 86 °C/W), making it the only drop-in solution for space-constrained 1 kV rectification without layout change or voltage derating.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for HS2MA-T?
The HS2MA-T has a confirmed VRRM rating of 1000 V, as specified in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version D2111). This value is explicitly assigned to the HS2MA-T variant and distinguishes it from lower-voltage members of the HS2x family such as HS2DA-T (200 V) and HS2KA-T (800 V). The 1000 V rating is validated under standard test conditions per JEDEC standards.
Does HS2MA-T support automated SMT placement, and what is its moisture sensitivity level?
Yes, HS2MA-T supports automated surface-mount placement due to its DO-214AC (SMA) package geometry and matte tin-plated leads compliant with J-STD-002. Its moisture sensitivity level is rated at Level 1 per J-STD-020, meaning it can be stored indefinitely at ≤30°C/85% RH without baking prior to reflow soldering - a key advantage for high-volume manufacturing lines.
What is the forward voltage (VF) of HS2MA-T at 2 A and 25°C, and how does it change at elevated temperature?
The HS2MA-T exhibits a maximum forward voltage of 1.40 V at 2 A and 25°C, and 1.41 V at 2 A and 125°C, as confirmed in the Electrical Specifications table. This minimal increase (0.01 V) reflects stable conduction characteristics across the full industrial temperature range, enabling predictable thermal modeling in power supply designs without significant derating.
Is HS2MA-T suitable for freewheeling applications in motor inverters, and what parameter supports this use?
Yes, HS2MA-T is suitable for freewheeling applications in motor inverters. Its 75 ns reverse recovery time (trr) - measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A - minimizes reverse recovery charge and associated switching losses during IGBT or MOSFET turn-off, directly supporting reliable operation in 10–20 kHz PWM-driven inverter stages.
What thermal resistance values are specified for HS2MA-T, and under what test condition?
HS2MA-T specifies RθJA = 86 °C/W, RθJC = 23 °C/W, and RθJL = 14 °C/W. These values are measured with the device mounted on a 5 mm × 5 mm copper pad on FR-4 PCB, per the Thermal Performance Note in the datasheet. RθJA is critical for estimating junction temperature rise in real-world layouts where board-level copper area is constrained.
