Product details
Overview
BAT54T RF from Taiwan Semiconductor is a dual-channel Schottky barrier diode in SOT-363 package, rated for 200mA forward current and 30V reverse voltage, with 1.0V forward drop at 100mA and 5ns reverse recovery time-used in high-speed switching and reverse polarity protection circuits.
For engineers reviewing the BAT54T RF datasheet, BAT54T RF pinout, BAT54T RF application, or BAT54T RF equivalent, key selection criteria include low VF (≤1.0V @ 100mA), fast trr (≤5 ns), SOT-363 thermal resistance (625°C/W), junction temperature range (–65°C to +150°C), and RoHS/halogen-free compliance for automotive and industrial PCB designs.
Technical Context
The BAT54T RF integrates two independent Schottky diodes in a single SOT-363 package with common-cathode configuration (pinout: 1–Anode1, 2–Cathode, 3–Anode2). It operates with minimal forward voltage drop and ultrafast recovery, enabling efficient clamping and signal steering in DC-DC converter feedback paths and USB port protection.
Its thermal performance (RθJA = 625°C/W) and moisture sensitivity level 1 rating support reflow-compatible assembly without baking, while JESD201 Class 1A whisker resistance ensures long-term solder joint reliability in vibration-prone environments.
Key Specifications

Applications
| USB Port Protection | DC-DC Converter Feedback Clamp |
|---|---|
Use Scenario: Prevents damage from reversed VBUS insertion or ESD-induced reverse bias in Type-A/Type-C receptacles. IC Role / Device Role / Timing Role: BAT54T RF acts as bidirectional clamping diode between VBUS and GND, limiting reverse voltage to <30 V. Use Value: 1.0 V forward drop ensures minimal impact on 5 V regulation margin; 5 ns trr avoids latch-up during hot-plug transients. | Use Scenario: Clamps feedback node voltage in synchronous buck converters to prevent op-amp saturation during light-load discontinuous conduction mode. IC Role / Device Role / Timing Role: BAT54T RF provides fast, low-VF clamp path from FB pin to reference rail, stabilizing regulation loop dynamics. Use Value: 10 pF junction capacitance avoids phase shift in high-gain feedback paths; SOT-363 size fits tight-layout converter IC footprints. |
| Reverse Polarity Input Protection | High-Speed Signal Steering |
Use Scenario: Installed in series with main power input to block reverse-connected batteries or adapters in portable instrumentation. IC Role / Device Role / Timing Role: BAT54T RF functions as low-loss series blocking diode using one channel, with second channel unused or paralleled for current sharing. Use Value: 200 mA continuous rating supports 12 V/100 mA sensor modules; 30 V VRRM covers 24 V nominal systems with surge margin. | Use Scenario: Routes clock or data signals between two microcontroller pins based on logic state in FPGA configuration interfaces. IC Role / Device Role / Timing Role: BAT54T RF serves as passive analog switch via forward-biased anode-cathode path, controlled by external bias voltage. Use Value: 5 ns trr supports ≤20 MHz signal routing; 10 pF CT prevents skew in matched-length differential pairs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2004K-7 | Single-channel SOT-23, 200 mA/30 V, VF = 0.55 V @ 100 mA, trr = 4 ns | Lacks dual-diode integration; requires two devices for BAT54T RF's dual-path functionality | Select when space permits discrete placement and lower VF is critical over integration |
| NSR0230P2T5G | Dual common-cathode SOT-363, 200 mA/30 V, VF = 0.45 V @ 100 mA, trr = 4.5 ns | Lower VF improves efficiency but higher leakage (IR = 10 μA @ 25 V vs. BAT54T RF's 2 μA) | Prefer for battery-powered systems where conduction loss dominates over leakage budget |
Compared with DMN2004K-7 and NSR0230P2T5G, the BAT54T RF offers balanced trade-offs: integrated dual topology in minimal area, moderate VF (1.0 V), ultra-low leakage (2 μA), and proven thermal robustness-making it optimal for space-constrained industrial and automotive signal conditioning.

FAQ
What is the pin configuration of the BAT54T RF?
The BAT54T RF uses a common-cathode dual-diode configuration in SOT-363: Pin 1 is Anode 1, Pin 2 is the shared Cathode, and Pin 3 is Anode 2. Pins 4–6 are internally unconnected and must remain floating or grounded per layout guidance. This arrangement enables independent clamping paths with minimal board area-critical for BAT54T RF deployment in multi-rail protection schemes.
Does the BAT54T RF meet automotive AEC-Q200 requirements?
The BAT54T RF is not AEC-Q200 qualified. While its –65°C to +150°C junction temperature range and JESD201 Class 1A whisker resistance support harsh environments, Taiwan Semiconductor does not list AEC-Q200 test reports for BAT54T RF. For automotive applications, users must perform system-level validation; BAT54T RF remains suitable for industrial and commercial-grade designs per its published specifications.
What is the maximum reverse leakage current for BAT54T RF at 25 V?
The maximum reverse leakage current for BAT54T RF is 2 μA at VR = 25 V and TJ = 25°C, measured per pulse test (PW = 30 ms). This low IR value ensures minimal standby power loss in always-on protection circuits and maintains signal integrity in high-impedance clamp nodes-key for reliable BAT54T RF operation in battery-backed systems.
Can BAT54T RF replace BAT54AD in the same PCB layout?
Yes, BAT54T RF and BAT54AD share identical SOT-363 packaging, pinout, and absolute maximum ratings-including 30 V VRRM, 200 mA IF, and 600 mA IFSM. Their marking codes differ (KLA vs. KL6), but electrically and mechanically they are interchangeable. No PCB changes are needed when substituting BAT54T RF for BAT54AD in existing designs.
What is the thermal resistance (RθJA) of BAT54T RF, and how does it affect power dissipation?
The junction-to-ambient thermal resistance of BAT54T RF is 625°C/W. At 200 mA and 1.0 V forward drop, power dissipation is 200 mW-resulting in a theoretical junction temperature rise of 125°C above ambient. Combined with its –65°C to +150°C TJ rating, this confirms BAT54T RF can safely operate at up to +25°C ambient in sealed enclosures without forced cooling.
