Product details
Overview
HS2MAL from Taiwan Semiconductor is a 2 A, 1000 V repetitive peak reverse voltage (VRRM) surface-mount fast recovery rectifier in a Thin SMA package, featuring 1.48 V max forward voltage at 2 A and 25°C, 75 ns reverse recovery time, and 12 pF junction capacitance - deployed in high-efficiency DC-DC converters and switching inverters.
For engineers reviewing the HS2MAL datasheet, HS2MAL pinout, HS2MAL application, or HS2MAL equivalent, key selection criteria include its 1000 V VRRM, thermal resistance of 17 °C/W (junction-to-lead), moisture sensitivity level 1 compliance, RoHS/halogen-free status, and suitability for automated SMT assembly in power conversion stages requiring low-profile, high-voltage rectification.
Technical Context
The HS2MAL operates as a single-die, unidirectional fast recovery rectifier optimized for high-frequency switching applications. Its 75 ns reverse recovery time (trr) and 12 pF junction capacitance (CJ) minimize switching losses and EMI generation in SMPS topologies.
Thermal performance is defined by RθJL = 17 °C/W and RθJA = 53 °C/W on a 5 mm × 5 mm Cu pad PCB, supporting continuous 2 A forward current (IF) with junction temperature maintained ≤150 °C under typical board-level cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - supports input rectification in 800 V AC line-derived or high-bus DC-DC systems without derating |
| IF | 2 A continuous - rated for sustained conduction in compact 10–50 W isolated flyback or forward converters |
| trr | 75 ns - enables operation up to ~500 kHz switching frequency while limiting turn-off loss and ringing |
| VF @ 2 A, 25°C | 1.48 V max - contributes <2.96 W conduction loss per device at full load, critical for thermal budgeting |
| CJ | 12 pF - reduces capacitive coupling noise and improves EMI filter effectiveness in high-dv/dt environments |
| RθJL | 17 °C/W - allows direct thermal path to PCB copper, enabling reliable operation without heatsink in space-constrained layouts |
| IFSM (8.3 ms) | 60 A - withstands inrush and transient overcurrent events common during power-up or fault conditions |
Pinout & Package
Package: Thin SMA (Surface Mount Axial), low-profile molded case meeting UL 94V-0; cathode indicated by band; matte tin-plated leads compliant with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |

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 |
|---|---|---|---|
| Vishay VS-2EYH01-M3/54 | Same 1000 V VRRM, 2 A IF, but 100 ns trr and 20 pF CJ; RθJA = 65 °C/W | Higher switching loss and reduced high-frequency efficiency; less suitable for >300 kHz designs | Select HS2MAL where faster recovery and lower capacitance are required for EMI-sensitive or high-frequency SMPS |
| ON Semiconductor MUR220RLG | 200 V VRRM, not voltage-compatible; otherwise similar 2 A/75 ns spec; TO-220AC package | Requires PCB redesign due to through-hole mounting and lower voltage rating; unsuitable for 1000 V applications | Only viable if system voltage is ≤200 V and through-hole assembly is acceptable; not a drop-in replacement |
Compared with VS-2EYH01-M3/54 and MUR220RLG, the HS2MAL delivers superior high-frequency performance via lower trr and CJ, tighter thermal resistance, and SMT compatibility - making it optimal for modern compact, high-efficiency, and automated production power supplies operating at ≥300 kHz.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for HS2MAL?
The HS2MAL has a maximum repetitive peak reverse voltage (VRRM) rating of 1000 V, verified per TSC datasheet revision C2103. This rating ensures safe operation under worst-case transient voltage conditions in 800 V DC bus or universal AC input applications. The HS2MAL maintains this rating across its full operating junction temperature range of –55°C to +150°C without derating.
Does HS2MAL support automated SMT placement, and what is its moisture sensitivity level?
Yes, HS2MAL supports automated surface-mount placement per its Thin SMA package design and J-STD-020 Level 1 moisture sensitivity classification. This means the device can be stored indefinitely at ambient conditions and placed directly into reflow without baking - simplifying manufacturing flow and reducing risk of popcorning or delamination during soldering.
What is the forward voltage (VF) of HS2MAL at 2 A and 25°C, and how does it change at elevated temperature?
The HS2MAL exhibits a maximum forward voltage (VF) of 1.48 V at 2 A and 25°C, dropping to 1.23 V max at 2 A and 125°C. This negative temperature coefficient improves thermal stability in parallel configurations and reduces conduction loss under high-temperature operating conditions typical in enclosed power supplies.
How does the reverse recovery time (trr) of HS2MAL compare to lower-voltage variants in the same family?
The HS2MAL has a trr of 75 ns, identical to HS2KAL and higher than HS2DAL (50 ns) and HS2GAL (50 ns), reflecting the trade-off between higher blocking voltage and carrier lifetime control. All HS2JAL/HS2KAL/HS2MAL variants share the same 75 ns trr specification, ensuring consistent switching behavior across the 600–1000 V segment of the family.
Is HS2MAL RoHS compliant and halogen-free, and which standards verify this?
Yes, HS2MAL is RoHS compliant and halogen-free per IEC 61249-2-21. These compliance statements are confirmed in the official TSC datasheet (Version C2103) and supported by material declarations issued by Taiwan Semiconductor. The device contains no brominated flame retardants (BFRs), antimony trioxide, or other restricted substances above threshold limits.
