Product details
Overview
RS2BA M2G 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 switching-mode power supplies.
For engineers reviewing the RS2BA M2G datasheet, RS2BA M2G pinout, RS2BA M2G application, or RS2BA M2G equivalent, key selection criteria include repetitive peak reverse voltage (100V), forward voltage drop at 1.5A (≤1.3V), thermal resistance (18°C/W junction-to-lead), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance.
Technical Context
This discrete silicon rectifier uses a glass-passivated PN junction to achieve fast recovery (150ns) with low forward voltage and minimal reverse leakage (5µA @ 25°C). Its single-die configuration and DO-214AC package support automated placement and high-density PCB layouts.
Thermal performance is defined by RθJL = 18°C/W and RθJA = 55°C/W, enabling reliable operation up to 175°C junction temperature. The cathode band polarity marking and matte tin-plated leads ensure compatibility with J-STD-002 soldering standards.
Key Specifications

| IF | 1.5 A - Continuous average forward current rating at 75°C lead temperature |
| IFSM | 50 A - Non-repetitive peak surge current (8.3ms half-sine), critical for inrush handling |
| trr | 150 ns - Reverse recovery time at IF=0.5A/IR=1.0A, determines switching loss in SMPS |
| VF | ≤1.3 V - Forward voltage at 1.5A and 25°C, directly impacts conduction loss and thermal design |
| RθJL | 18 °C/W - Junction-to-lead thermal resistance, enables direct heatsinking via PCB copper |
| TJ max | 175 °C - Maximum allowable junction temperature, sets upper limit for thermal margin |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06U (STMicroelectronics) | Same 1.5A/100V rating; 75ns trr; TO-277A package (smaller footprint, no leads) | Higher switching speed suits >500kHz designs; leadless package requires different stencil and reflow profile | Prefer when minimizing reverse recovery loss is critical and layout allows SMD leadless assembly |
| ES1B (ON Semiconductor) | 1A/100V; 35ns trr; same DO-214AC package; lower IF and IFSM (30A) | Lower current rating limits use to sub-1A auxiliary rails; faster recovery reduces EMI in noise-sensitive analog sections | Choose for low-noise, low-power bias supplies where 1.5A headroom is unnecessary |
Compared with STTH1L06U and ES1B, RS2BA M2G offers balanced trade-offs: sufficient 1.5A/50A ratings for general-purpose SMPS, proven DO-214AC manufacturability, and 150ns recovery suitable for 100–300kHz operation without excessive cost or layout complexity.

FAQ
What is the maximum junction temperature rating for RS2BA M2G?
The RS2BA M2G has a maximum junction temperature (TJ) rating of +175°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet Version I2304. This allows operation in high-ambient environments such as enclosed industrial power supplies. Derating curves confirm usable current capacity down to 0.8A at 125°C case temperature. RS2BA M2G must be mounted on adequate copper area to maintain this limit under full load.
Does RS2BA M2G meet RoHS and halogen-free requirements?
Yes, RS2BA M2G is RoHS compliant and halogen-free, as explicitly stated in the "Features" section of the Taiwan Semiconductor datasheet (Version I2304). The molding compound and plating materials have been certified to meet EU Directive 2011/65/EU and IEC 61249-2-21:2011 standards. RS2BA M2G carries the "G" suffix in its marking code to denote green/halogen-free construction.
What is the reverse recovery time (trr) specification for RS2BA M2G?
The reverse recovery time (trr) for RS2BA M2G is 150ns, measured under conditions of IF = 0.5A, IR = 1.0A, and Irr = 0.25A, per the Electrical Specifications table in the Taiwan Semiconductor datasheet. This value applies specifically to the RS2BA variant; higher-voltage members (e.g., RS2JA) specify longer trr. RS2BA M2G's 150ns trr supports efficient operation in 100–300kHz switching power supplies.
Is RS2BA M2G compatible with standard DO-214AC (SMA) footprints?
Yes, RS2BA M2G uses the JEDEC DO-214AC (SMA) package with exact dimensions matching the standard outline: 4.06mm × 2.29mm body, 2.50mm lead spacing, and cathode band polarity marking. The datasheet confirms compliance with JEDEC DO-214 Variation AC Issue D and provides recommended pad layout dimensions. RS2BA M2G is fully compatible with existing SMA land patterns and pick-and-place tooling.
What is the forward voltage drop (VF) of RS2BA M2G at rated current?
The forward voltage drop (VF) of RS2BA M2G is specified as a maximum of 1.3V at IF = 1.5A and TJ = 25°C, per the Electrical Specifications table. At elevated temperatures (e.g., 125°C), VF decreases slightly due to semiconductor physics. This VF value directly determines conduction loss: at 1.5A, RS2BA M2G dissipates ≤1.95W, requiring appropriate thermal design. The typical VF is lower but not guaranteed.
