Product details
Overview
RS2BAHM2G from Taiwan Semiconductor is a 1.5A, 100V fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 50A peak surge current, 175°C max junction temperature, and 150ns reverse recovery time. It serves as a primary output rectifier in DC-DC converters and snubber circuits where fast switching and thermal robustness are required.
For engineers reviewing the RS2BAHM2G datasheet, RS2BAHM2G pinout, RS2BAHM2G application, or RS2BAHM2G equivalent, key selection criteria include VRRM=100V, IF=1.5A, trr=150ns, RθJA=55°C/W, and DO-214AC mechanical compatibility with automated SMT placement.
Technical Context
This single-die fast recovery rectifier uses glass-passivated junction technology to achieve stable reverse leakage (<5µA at 25°C, <200µA at 125°C) and low forward voltage drop (max 1.3V at 1.5A/25°C). Its 18°C/W junction-to-lead thermal resistance supports high-power-density board layouts.
The device meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity, enabling reflow compatibility without baking. Cathode polarity is marked by a visible band on the SMA body, and terminals are matte tin-plated for reliable solderability per J-STD-002.
Key Specifications

| VRRM | 100 V - Maximum repetitive reverse voltage; defines safe blocking capability in 100V-rated power rails |
| IF | 1.5 A - Continuous forward current rating; determines steady-state conduction capacity in output stages |
| trr | 150 ns - Reverse recovery time; enables efficient operation up to ~1 MHz switching frequencies in SMPS |
| RθJA | 55 °C/W - Junction-to-ambient thermal resistance; informs heatsinking requirements on standard FR-4 PCB |
| VF @ 1.5A | ≤1.3 V - Forward voltage drop; directly impacts conduction loss and thermal load at full rated current |
| IFSM | 50 A - Non-repetitive surge current (8.3ms half-sine); supports inrush and fault-current handling |
| Junction temp | –55°C to +175°C - Operating range; allows deployment in automotive under-hood and industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06S | VRRM=600V, IF=1A, trr=50ns, DO-214AC | Higher voltage rating but lower current; faster recovery | Select when system requires >100V blocking with tighter trr budget, accepting 33% lower IF |
| MBR15100CT | Dual common-cathode Schottky, 100V, 15A total, TO-220AC | Higher current, lower VF, but larger package and no fast-recovery optimization | Choose for higher-efficiency, lower-VF needs where space and thermal mass allow TO-220 mounting |
Compared with STTH1L06S and MBR15100CT, RS2BAHM2G offers optimal balance of 100V rating, 1.5A current, 150ns speed, and DO-214AC SMT compatibility-making it ideal for compact, cost-sensitive 100V-output power supplies where Schottky leakage or ultra-high-voltage capability are not required.

FAQ
What is the maximum junction temperature rating for RS2BAHM2G?
The RS2BAHM2G has a maximum junction temperature (TJMAX) of +175°C, allowing operation in high-ambient environments such as enclosed power supplies or under-hood automotive modules. This rating is validated per TSC's absolute maximum ratings table and supports derating curves up to 175°C ambient with appropriate PCB copper area.
Is RS2BAHM2G compatible with lead-free reflow processes?
Yes, RS2BAHM2G is fully compatible with lead-free reflow. Its matte tin-plated leads meet J-STD-002 solderability requirements, and its Level 1 moisture sensitivity per J-STD-020 eliminates the need for pre-baking-enabling direct placement into standard IPC/JEDEC-compliant reflow profiles.
What does the 'HM2G' suffix indicate in RS2BAHM2G?
The 'HM2G' suffix in RS2BAHM2G denotes Taiwan Semiconductor's packaging and compliance coding: 'H' = halogen-free compound, 'M2' = DO-214AC (SMA) tape-and-reel packaging (7,500 units per reel), and 'G' = RoHS-compliant green marking. This matches TSC's official ordering nomenclature in the datasheet.
How does RS2BAHM2G compare to RS2AA in terms of electrical performance?
RS2BAHM2G and RS2AA share identical package, current rating (1.5A), thermal specs, and recovery time (150ns), but differ in VRRM: RS2BAHM2G is rated for 100V, while RS2AA is rated for 50V. All other parameters-including VF, IFSM, and leakage-are specified identically within their respective voltage classes.
Can RS2BAHM2G be used as a direct replacement for RS2BAM2G?
Yes, RS2BAHM2G and RS2BAM2G are functionally identical part numbers from Taiwan Semiconductor-the 'H' and 'M' suffixes both denote halogen-free material per TSC's internal coding revision. No electrical, mechanical, or reliability differences exist between them; RS2BAHM2G is the current standardized marking.
