Product details
Overview
HS2MALH from Taiwan Semiconductor is a 1000V, 2A surface-mount high-efficiency fast recovery rectifier diode in a Thin SMA package, featuring 1.48V max forward voltage at 2A/25°C, 75ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or snubber diode in DC/DC converters operating under high-voltage, moderate-current conditions.
For engineers reviewing the HS2MALH datasheet, HS2MALH pinout, HS2MALH application, or HS2MALH equivalent, key selection criteria include peak reverse voltage (1000V), thermal resistance (RθJA = 53°C/W), junction capacitance (12pF), and AEC-Q101 qualification - all critical for automotive power conversion and industrial SMPS design.
Technical Context
The HS2MALH implements a single-die, glass-passivated PN junction optimized for fast switching and low conduction loss at high blocking voltages. Its 1000V VRRM rating enables use in 800V-class bus systems, while its 75ns trr supports operation up to several hundred kHz in hard-switched topologies.
Thermal performance is defined by RθJL = 17°C/W and RθJA = 53°C/W on a 5mm × 5mm Cu pad, supporting continuous 2A operation at TA ≤ 95°C. The device's 12pF junction capacitance minimizes capacitive switching losses and EMI generation in high-frequency applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-2EY100-M3/54 | 1000V VRRM, 2A IF, 1.25V VF @ 2A, 50ns trr, SMA package | Lower VF and faster trr, but not AEC-Q101 qualified | Preferred where efficiency > automotive qualification; requires validation for automotive use |

FAQ
What is the maximum repetitive peak reverse voltage of the HS2MALH?
The HS2MALH has a maximum repetitive peak reverse voltage (VRRM) of 1000 V, verified per the manufacturer's absolute maximum ratings table. This rating allows the HS2MALH to safely block transient overvoltages in 800V-class DC bus systems. The 1000V rating is specific to the HS2MALH variant and differs from lower-voltage members like HS2DALH (200V) or HS2GALH (400V). Derating is recommended above 125°C junction temperature.
Is the HS2MALH qualified for automotive applications?
Yes, the HS2MALH is AEC-Q101 qualified, confirming it meets the stress test requirements for automotive discrete semiconductors, including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing. This qualification applies specifically to the HS2MALH part number as shipped in Thin SMA packaging and is documented in Taiwan Semiconductor's official qualification report version B2103.
What is the forward voltage drop of the HS2MALH at 2A and 25°C?
The HS2MALH exhibits a maximum forward voltage (VF) of 1.70 V at 2A and 25°C, with a typical value of 1.48 V under the same conditions. This parameter is measured using pulse testing (PW = 0.3 ms) to avoid self-heating effects. At 125°C, VF drops to 1.23 V max due to semiconductor physics, improving conduction efficiency at elevated temperatures.
Does the HS2MALH have a specified reverse recovery time?
Yes, the HS2MALH has a specified reverse recovery time (trr) of 75 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value applies to all variants from HS2JALH through HS2MALH and is confirmed in the Electrical Specifications section of the datasheet. The 75 ns trr enables efficient operation in switching power supplies operating up to 500 kHz.
What package type does the HS2MALH use, and what are its key mechanical features?
The HS2MALH uses the Thin SMA (DO-214AC) surface-mount package, characterized by low profile height (<1.1 mm), matte tin-plated leads compliant with J-STD-002, and a cathode band for polarity identification. Its molding compound meets UL 94V-0 flammability rating, and the device is rated at moisture sensitivity level 1 per J-STD-020 - meaning it can be stored indefinitely before reflow without baking.
