Product details
Overview
HS2MAH from Taiwan Semiconductor is a 1000V, 1.5A surface-mount fast recovery rectifier diode in DO-214AC (SMA) package, featuring 1.7V forward voltage at 1.5A and 75ns reverse recovery time, used for freewheeling and snubber circuits in automotive DC-DC converters and lighting systems.
For engineers reviewing the HS2MAH datasheet, HS2MAH pinout, HS2MAH application, or HS2MAH equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (80°C/W), junction capacitance (30pF), AEC-Q101 qualification, and moisture sensitivity level 1 compliance.
Technical Context
This device is a single-die, glass-passivated silicon rectifier optimized for high-efficiency switching applications. Its 1000V VRRM, 50A IFSM, and 150°C maximum junction temperature support robust operation in automotive transients and industrial power rails.
The 75ns reverse recovery time and 30pF junction capacitance at 1MHz/4V are measured under standardized conditions (IF=0.5A, IR=1.0A, Irr=0.25A), enabling stable performance in high-frequency flyback and clamp circuits where switching loss minimization is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Maximum repetitive reverse voltage the device blocks without breakdown; defines safe operating range in 400–800V bus applications. |
| IF | 1.5 A - Continuous average forward current at TA=25°C; derates to zero at 150°C per published curve. |
| VF | 1.7 V @ 1.5A - Forward voltage drop determining conduction loss and thermal load in high-duty-cycle rectification. |
| trr | 75 ns - Reverse recovery time defining switching speed and associated turn-off losses in hard-switched topologies. |
| CJ | 30 pF @ 1MHz, 4V - Junction capacitance affecting high-frequency noise coupling and resonant behavior in snubber networks. |
| RθJA | 80 °C/W - Junction-to-ambient thermal resistance; determines required PCB copper area and airflow for thermal management. |
| IFSM | 50 A - Non-repetitive surge current capability for handling inrush or fault transients without failure. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L100S | 1000V VRRM, 1A IF, 75ns trr, TO-277 package | Lower current rating limits use to ≤1A average loads; higher thermal resistance requires larger heatsinking. | Select when footprint flexibility allows TO-277 and system current demand is ≤1A. |
| ES1J-M3/84A | 600V VRRM, 1A IF, 35ns trr, SMA package | Insufficient VRRM for 400V+ bus applications; faster recovery but lower voltage margin. | Select only for sub-400V systems where ultra-fast recovery outweighs voltage derating needs. |
Compared with STTH1L100S and ES1J-M3/84A, the HS2MAH uniquely delivers 1.5A current handling in SMA with 1000V rating and AEC-Q101 qualification-making it the only option among the three validated for automotive 48V–400V DC-DC and lighting modules requiring both high voltage and high current in low-profile packaging.

FAQ
What is the peak repetitive reverse voltage rating of the HS2MAH?
The HS2MAH has a peak repetitive reverse voltage (VRRM) rating of 1000V. This value is explicitly specified in the absolute maximum ratings table for the HS2MAH variant and defines the maximum reverse-biased voltage the device can block repeatedly without breakdown. It is verified across production lots and confirmed in the A2102 datasheet revision.
Is the HS2MAH qualified for automotive applications?
Yes, the HS2MAH is AEC-Q101 qualified. This qualification is stated in the FEATURES section of the official datasheet and applies specifically to the HS2AAH–HS2MAH family. The qualification includes stress tests for temperature cycling, high-temperature reverse bias, and mechanical shock-ensuring suitability for under-hood automotive environments.
What is the forward voltage drop of the HS2MAH at rated current?
The HS2MAH exhibits a maximum forward voltage (VF) of 1.7V at 1.5A and 25°C junction temperature, as specified in the ELECTRICAL SPECIFICATIONS table. This value is measured under pulsed conditions (PW = 0.3ms) and directly impacts conduction loss and thermal design in high-current rectification paths.
Does the HS2MAH have a defined reverse recovery time?
Yes, the HS2MAH has a reverse recovery time (trr) of 75ns, measured under standardized conditions (IF = 0.5A, IR = 1.0A, Irr = 0.25A). This parameter is explicitly listed in the ELECTRICAL SPECIFICATIONS table for the HS2JAH–HS2MAH group and confirms its classification as a fast recovery rectifier.
What package type does the HS2MAH use?
The HS2MAH uses the DO-214AC (SMA) surface-mount package, as confirmed in the MECHANICAL DATA and ORDERING INFORMATION sections. Key attributes include matte tin-plated leads, polarity indicated by cathode band, UL 94V-0 molding compound, and a typical weight of 0.060g.
