Product details
Overview
BAT54T RFG from Taiwan Semiconductor is a dual-channel Schottky barrier diode in SOT-363 package, rated for 200 mA forward current and 30 V repetitive peak reverse voltage, with 1.0 V forward voltage at 100 mA and 5 ns reverse recovery time - used for high-speed clamping and polarity protection in compact DC power rails.
For engineers reviewing the BAT54T RFG datasheet, BAT54T RFG pinout, BAT54T RFG application, or BAT54T RFG equivalent, key selection criteria include low VF at low-to-moderate currents, sub-10 ns trr for fast switching, SOT-363 footprint compatibility, thermal resistance of 625°C/W, and moisture sensitivity level 1 handling requirements.
Technical Context
The BAT54T RFG integrates two independent Schottky diodes in a single SOT-363 package with common cathode configuration (pinout: 1–Anode1, 2–Cathode, 3–Anode2). It operates across –65°C to +150°C junction temperature range and supports pulse forward surge up to 600 mA.
Its 10 pF junction capacitance at 1 V reverse bias and 2 μA max reverse leakage at 25 V enable stable performance in signal-level clamping and low-power logic interface protection without introducing significant capacitive loading or standby loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (Continuous) | 200 mA - supports sustained current in USB port protection or I/O rail clamping |
| VRRM | 30 V - suitable for 24 V industrial control inputs and 5 V/3.3 V logic-level circuits |
| VF @ 100 mA | 1.00 V - minimizes conduction loss in low-voltage reverse polarity schemes |
| trr | 5 ns - enables use in >10 MHz digital signal line protection without timing distortion |
| RθJA | 625 °C/W - requires careful PCB copper area planning for thermal management above 100 mW dissipation |
| CT @ 1 V | 10 pF - low enough to avoid signal integrity degradation on high-speed data lines |
Pinout & Package
SOT-363 (SC-70-6) surface-mount package with 6-pin lead frame, matte tin-plated terminals, UL 94V-0 molding compound, and moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 | Connects to protected input or supply rail requiring forward conduction path |
| 2 | Common Cathode | Shared cathode node; ties both diodes to reference ground or return path |
| 3 | Anode of Diode 2 | Independent anode for second clamping or polarity channel |
| 4 | No Connect | Internally unconnected; must be left floating or grounded per layout guidelines |
| 5 | No Connect | Internally unconnected; no electrical function |
| 6 | No Connect | Internally unconnected; no electrical function |
Key Features
| Feature | Design Value |
|---|---|
| Fast switching speed | 5 ns reverse recovery time enables reliable operation in 10–50 MHz signal line protection |
| Low forward voltage drop | 1.0 V at 100 mA reduces power loss and heat generation in battery-powered systems |
| Moisture sensitivity level 1 | No bake preconditioning required before reflow, simplifying SMT assembly flow |
| RoHS & halogen-free compliance | Meets IEC 61249-2-21 and EU RoHS directives for environmentally constrained applications |
Applications
| USB Port Protection | Industrial Sensor Interface |
|---|---|
Use Scenario: Protecting USB 2.0 data lines and VBUS against ESD-induced reverse transients and hot-plug polarity reversal. IC Role / Device Role / Timing Role: Dual Schottky clamp performing bidirectional voltage limiting and reverse current blocking. Use Value: 5 ns trr prevents data eye closure; 10 pF CT avoids signal rise-time degradation on 480 Mbps lines. | Use Scenario: Isolating analog sensor outputs (e.g., 4–20 mA loop transmitters) from field-wiring polarity errors. IC Role / Device Role / Timing Role: Reverse polarity protection diode pair ensuring safe power-up regardless of terminal orientation. Use Value: 1.0 V VF at 100 mA limits insertion loss to <2% in 24 V loop designs; SOT-363 fits tight board space. |
| Logic-Level Signal Clamping | Low-Power Microcontroller I/O Protection |
Use Scenario: Clamping SPI/MICROWIRE clock and data lines to prevent overvoltage beyond MCU absolute maximum ratings. IC Role / Device Role / Timing Role: Fast-turn-on Schottky clamp diverting transient energy to ground before IC damage occurs. Use Value: Sub-1 V turn-on threshold activates before 3.3 V logic rails exceed 4.0 V; 2 μA IR ensures negligible standby leakage. | Use Scenario: Safeguarding GPIO pins of ARM Cortex-M0+ microcontrollers during firmware development and field deployment. IC Role / Device Role / Timing Role: Dual-diode structure provides independent protection for multiple I/O banks sharing a common ground reference. Use Value: Common-cathode topology allows shared ground connection; 6.99 mg weight supports ultra-lightweight portable designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2004LKQ-7 | Single-channel SOT-363 Schottky; 200 mA IF, 20 V VRRM, 0.45 V VF @ 100 mA | Limited to single-diode functions; lower VR rating restricts use in 24 V systems | Select when only one protection path is needed and lower VF is prioritized over voltage headroom |
| SBAT54LT1G | Dual common-cathode Schottky in SOT-23-6; 200 mA IF, 30 V VRRM, 1.0 V VF @ 100 mA, 6 ns trr | Same electrical specs but larger SOT-23-6 footprint; higher RθJA (700°C/W) | Choose if existing layout uses SOT-23-6 or requires higher mechanical robustness at cost of board area |
Compared with DMN2004LKQ-7 and SBAT54LT1G, the BAT54T RFG uniquely balances dual-diode functionality, 30 V rating, and SOT-363 miniaturization - making it optimal for space-constrained dual-rail protection where thermal budget and voltage margin are both critical.

FAQ
What is the pin configuration of BAT54T RFG?
The BAT54T RFG uses a common-cathode dual-diode configuration in SOT-363: Pin 1 = Anode 1, Pin 2 = Common Cathode, Pin 3 = Anode 2, Pins 4–6 = No Connect. This layout supports independent clamping paths sharing a ground reference, confirmed in TSC's H2111 datasheet revision.
Is BAT54T RFG RoHS and halogen-free compliant?
Yes, BAT54T RFG meets EU RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21, as explicitly stated in the "FEATURES" section of the official Taiwan Semiconductor datasheet (Version H2111).
What is the maximum junction temperature for BAT54T RFG?
The BAT54T RFG has a maximum junction temperature (TJ MAX) of +150°C and a minimum of –65°C, supporting operation in extended industrial environments. Derating begins above 25°C ambient per the published power derating curve.
Does BAT54T RFG have moisture sensitivity level (MSL) restrictions?
Yes, BAT54T RFG is rated MSL Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH and requires no baking prior to reflow soldering - simplifying manufacturing for high-volume SMT lines.
What is the reverse leakage current specification for BAT54T RFG?
The BAT54T RFG specifies a maximum reverse current (IR) of 2 μA at VR = 25 V and TJ = 25°C, measured under 30 ms pulse conditions. This low leakage supports reliable long-term operation in battery-backed and always-on circuits.
