Product details
Overview
HS2MA 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 high-voltage DC-DC converters.
For engineers reviewing the HS2MA datasheet, HS2MA pinout, HS2MA application, or HS2MA equivalent, key selection criteria include peak repetitive reverse voltage (1000V), surge current rating (50A), thermal resistance (80°C/W), junction temperature range (–55°C to +150°C), and low-profile SMA packaging for automated assembly.
Technical Context
The HS2MA employs a single-die, glass-passivated PN junction optimized for high-efficiency switching in high-voltage power conversion stages. Its 75ns trr and 30pF junction capacitance support operation up to several hundred kHz in flyback and forward topologies.
Designed for operation at TJ = –55°C to +150°C with 50A IFSM capability, the HS2MA maintains stable reverse leakage (<100µA at 125°C) and exhibits low thermal resistance (RθJA = 80°C/W) in its DO-214AC package, enabling compact board-level thermal management without heatsinking at rated current.

| IF | 1.5 A continuous - suitable for medium-power SMPS outputs up to ~30W |
| IFSM | 50 A - withstands transient surges in inductive load switching |
| VF @ 1.5A | 1.7 V - contributes ~2.55W conduction loss at full load |
| trr | 75 ns - enables efficient operation in 100–300 kHz switching converters |
| CJ | 30 pF @ 1MHz, 4V - minimizes capacitive switching losses and EMI generation |
| RθJA | 80 °C/W - allows natural convection cooling on standard FR-4 PCBs |

|---|---|
Use Scenario: Secondary-side synchronous or non-synchronous rectification in isolated flyback or forward converters delivering 12–48V outputs. IC Role / Device Role / Timing Role: Unidirectional current path enabling energy transfer during transformer reset phase. Use Value: 1000V VRRM safely handles reflected transients; 1.7V VF balances conduction loss and thermal rise at 1.5A. | Use Scenario: RCD snubber across MOSFET drain-source in high-voltage switching circuits (e.g., PFC boost, motor drives). IC Role / Device Role / Timing Role: Fast clamping diode that conducts transient energy into capacitor during voltage spikes. Use Value: 75ns trr ensures rapid turn-on before voltage overshoot exceeds safe margin; 50A IFSM absorbs multiple surge events. |
| Freewheeling in Inductive Loads | Lighting Ballast Circuits |
Use Scenario: Freewheel path for relay coils, solenoids, or transformer windings in industrial control modules. IC Role / Device Role / Timing Role: Provides low-impedance return path for stored inductive energy during switch-off. Use Value: 1000V rating prevents breakdown during L·di/dt-induced voltage spikes; glass passivation ensures field longevity. | Use Scenario: High-voltage rectification in LED driver front-end stages or HID lamp ballasts operating from 277–480V AC mains.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06 | 600V VRRM, 1.0A IF, 50ns trr, TO-220AC package | Limited to ≤600V systems; requires through-hole mounting and heatsinking above 0.5A | Prefer HS2MA where 1000V rating, SMT assembly, or higher surge tolerance is required |
| ES1J-M3/5AT | 600V VRRM, 1.0A IF, 35ns trr, DO-214AC package | Faster recovery but lower voltage rating and current capacity; not suitable for >600V bus designs | Choose HS2MA when system peak reverse voltage exceeds 600V or 1.5A continuous current is needed |
Compared with STTH1L06 and ES1J-M3/5AT, the HS2MA uniquely delivers 1000V blocking capability in a surface-mount DO-214AC package with 1.5A rating-enabling compact, high-reliability rectification in 800–1000V transient-prone applications without layout or thermal redesign.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for HS2MA?
The HS2MA has a maximum repetitive peak reverse voltage (VRRM) of 1000 V, verified per Taiwan Semiconductor's J2102 datasheet. This rating allows the HS2MA to safely block high-voltage transients in offline power supplies, PFC stages, and industrial motor drive snubbers. The 1000V specification is confirmed in the Absolute Maximum Ratings table and applies under standard test conditions (TA = 25°C).
What is the forward voltage drop of HS2MA at 1.5A and 25°C?
The forward voltage drop (VF) of the HS2MA is 1.7 V at IF = 1.5 A and TJ = 25°C, as specified in the Electrical Specifications table under "Forward voltage(1)" for the HS2JA/HS2KA/HS2MA group. This value is measured using a 0.3ms pulse test and reflects typical conduction loss behavior in real-world switching applications.
Does HS2MA have a defined reverse recovery time (trr), and what is its value?
Yes, the HS2MA has a reverse recovery time (trr) of 75 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter is explicitly listed in the Electrical Specifications table for the HS2JA/HS2KA/HS2MA variants and confirms its suitability for high-frequency switching applications up to ~300 kHz.
What package type does HS2MA use, and is it RoHS compliant?
The HS2MA uses the DO-214AC (SMA) surface-mount package with matte tin-plated leads and is RoHS compliant and halogen-free per IEC 61249-2-21. Its mechanical data confirm UL 94V-0 flammability rating, J-STD-002 solderability, and JESD 201 Class 2 whisker resistance-making it suitable for automated assembly and environmentally regulated end products.
What is the junction-to-ambient thermal resistance (RθJA) of HS2MA?
The junction-to-ambient thermal resistance (RθJA) of the HS2MA is 80 °C/W, as published in the Thermal Performance section of the datasheet. This value assumes standard mounting on FR-4 PCB with minimum copper area and natural convection cooling, and enables thermal design without forced airflow or heatsinks at 1.5A continuous current.
