Product details
Overview
HS2MH from Taiwan Semiconductor is a 1000 V, 2 A 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. It serves as a high-voltage freewheeling or snubber diode in automotive DC-DC converters and LED lighting systems.
For engineers reviewing the HS2MH datasheet, HS2MH pinout, HS2MH application, or HS2MH equivalent, key selection criteria include its 1000 V repetitive peak reverse voltage, 50 A surge rating, AEC-Q101 qualification, RoHS/halogen-free compliance, and thermal resistance of 80 °C/W.
Technical Context
This device is a single-die, glass-passivated silicon junction rectifier optimized for fast switching and low conduction loss in high-voltage, moderate-current applications. Its 75 ns trr and 30 pF junction capacitance support efficient operation in 100–500 kHz DC-DC topologies.
Designed for automotive-grade reliability, HS2MH meets AEC-Q101 stress test requirements and operates across –55 °C to +150 °C junction temperature range, with matte tin-plated leads compliant to J-STD-002 solderability and JESD201 Class 2 whisker resistance.

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 | Same DO-214AA package; 1000 V VRRM; 1.85 V VF @ 2 A; 100 ns trr | Higher VF increases conduction loss by ~0.3 W; slower trr raises switching loss in >200 kHz designs | Acceptable where thermal headroom exists and switching frequency ≤150 kHz |
| ON Semiconductor MUR220 | DO-204AL (DO-41); 200 V VRRM only; not voltage-compatible with HS2MH | Not suitable for 1000 V applications; requires redesign of voltage rating and layout | Only viable if system voltage reduced to ≤200 V and through-hole assembly accepted |
Compared with VS-2EY100 and MUR220, HS2MH delivers superior high-frequency efficiency due to its 75 ns trr and lower VF, while maintaining AEC-Q101 qualification and SMB footprint-making it the preferred choice for automotive and industrial 1000 V rectification where space, reliability, and dynamic performance are critical.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of HS2MH?
The HS2MH has a VRRM rating of 1000 V, verified per TSC datasheet A2102. This allows the HS2MH to safely block reverse voltages up to 1000 V in continuous operation, making it suitable for high-voltage DC bus applications such as automotive 48 V systems and industrial power supplies with elevated input rails.
Is HS2MH qualified for automotive applications?
Yes, HS2MH is AEC-Q101 qualified, as confirmed in the official Taiwan Semiconductor datasheet. This qualification covers stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing-ensuring HS2MH meets reliability requirements for under-hood automotive power electronics.
What is the forward voltage drop of HS2MH at rated current?
HS2MH exhibits a typical forward voltage (VF) of 1.7 V at 2 A and 25 °C junction temperature, per electrical specifications in the TSC datasheet. This value increases with temperature and current, reaching approximately 1.85 V at 125 °C, directly impacting conduction loss and thermal design of the HS2MH in circuit.
Does HS2MH have a defined reverse recovery time (trr)?
Yes, HS2MH has a specified reverse recovery time of 75 ns under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A test conditions. This fast trr enables efficient operation in high-frequency switching power supplies and reduces switching losses compared to standard recovery rectifiers.
What package type does HS2MH use, and is it compatible with automated assembly?
HS2MH uses the DO-214AA (SMB) surface-mount package with matte tin-plated leads compliant to J-STD-002. Its standardized footprint and lead finish ensure full compatibility with automated pick-and-place equipment and standard reflow soldering processes used in high-volume PCB manufacturing.
