Product details
Overview
BAT54BR RFG from Taiwan Semiconductor is a dual-channel Schottky barrier diode in SOT-363 package, rated for 30 V repetitive peak reverse voltage, 200 mA forward current, and 1.0 V forward voltage at 100 mA - used for high-speed reverse polarity protection and clamping in compact DC power rails.
For engineers reviewing the BAT54BR RFG datasheet, BAT54BR RFG pinout, BAT54BR RFG application, or BAT54BR RFG equivalent, key selection factors include its 5 ns reverse recovery time, 10 pF junction capacitance at 1 V, moisture sensitivity level 1 rating, and dual-diode configuration with independent anode-cathode pairs in a 6-pin SOT-363 footprint.
Technical Context
The BAT54BR RFG integrates two independent Schottky diodes sharing a common cathode connection (configuration BR), enabling bidirectional clamping or dual-path reverse polarity protection without external wiring. Its low VF (≤1.0 V @ 100 mA) and fast trr (≤5 ns) support efficient switching in 1–10 MHz DC/DC feedback paths and USB port protection circuits.
Thermal performance is defined by RθJA = 625°C/W and TJ range of –65°C to +150°C, allowing operation in thermally constrained industrial and automotive under-hood modules. The device meets JESD201 Class 1A whisker resistance and RoHS/halogen-free compliance per IEC 61249-2-21.
Key Specifications

Applications
| USB Port Protection | Industrial Sensor Bias Rail Clamping |
|---|---|
Use Scenario: Protecting downstream USB 2.0 data lines and VBUS from ESD-induced reverse transients and hot-plug polarity reversal. IC Role / Device Role / Timing Role: BAT54BR RFG acts as dual-rail clamping diode array, shunting reverse current from D+ and D− to ground while preserving signal rise/fall times. Use Value: 5 ns trr and 10 pF CT prevent signal distortion on 480 Mbps data lines; common-cathode layout simplifies PCB routing. | Use Scenario: Clamping bias voltage spikes on 3.3 V or 5 V analog sensor supply lines exposed to inductive load switching noise. IC Role / Device Role / Timing Role: BAT54BR RFG provides low-VF crowbar clamping across sensor VDD and GND, limiting overvoltage to <1.0 V above rail. Use Value: 1.0 V VF at 100 mA ensures minimal voltage droop during transient suppression; SOT-363 fits tight sensor module footprints. |
| Automotive Body Control Module Inputs | Low-Power IoT Node Reverse Polarity Protection |
Use Scenario: Safeguarding microcontroller GPIOs and LIN bus transceivers against battery-reverse connection during service or jump-start events. IC Role / Device Role / Timing Role: BAT54BR RFG serves as input-stage reverse polarity blocker, using one diode per signal line with shared cathode to chassis ground. Use Value: –65°C to +150°C operating range matches BCM under-hood thermal profiles; MSL-1 allows direct placement without dry-pack handling. | Use Scenario: Preventing damage to coin-cell-powered BLE/Wi-Fi modules when users insert batteries backward in consumer IoT enclosures. IC Role / Device Role / Timing Role: BAT54BR RFG functions as dual-path series blocking diode, placed between battery terminals and PMIC input, with each anode accepting either polarity. Use Value: 200 mA IF supports typical 10–50 mA IoT sleep/active currents; 6.99 mg weight avoids mechanical stress on flex PCBs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2016LFG-7 | Single-channel, 20 V VRRM, 1.2 A IF, SOT-23 package | Higher current, lower voltage rating; no dual-diode topology | Select only if single-rail protection suffices and board space permits larger SOT-23 footprint |
| NSR0230P2T5G | Dual common-anode configuration (not common-cathode), 30 V, 200 mA, SOT-363 | Inverted polarity logic - requires redesign of ground referencing and clamping direction | Use only when circuit architecture mandates anode-common topology and layout revision is acceptable |
Compared with DMN2016LFG-7 and NSR0230P2T5G, the BAT54BR RFG uniquely delivers dual common-cathode Schottky functionality in SOT-363 with verified 5 ns trr and MSL-1 handling - making it optimal for space-constrained, dual-rail reverse polarity or clamping designs where ground-referenced protection is required.

FAQ
What is the pin configuration of BAT54BR RFG?
The BAT54BR RFG uses a common-cathode dual-Schottky configuration in SOT-363: Pin 1 and Pin 5 are independent anodes; Pins 2 and 6 are internally bonded common cathodes; Pins 3 and 4 are no-connect. This layout enables two separate forward paths sharing one ground node - critical for dual-rail clamping without cross-talk.
Does BAT54BR RFG support reflow soldering without baking?
Yes, BAT54BR RFG has Moisture Sensitivity Level 1 per J-STD-020, meaning it can be mounted directly onto PCBs using standard lead-free reflow profiles without pre-bake. This eliminates process steps and reduces risk of moisture-induced popcorning during assembly - confirmed in TSC's H2111 datasheet revision.
What is the maximum reverse recovery time specified for BAT54BR RFG?
The BAT54BR RFG has a maximum reverse recovery time (trr) of 5 ns under test conditions of IF = IR = 10 mA, RL = 100 Ω, and IRR = 1 mA. This value is measured per diode and ensures clean switching behavior in high-frequency applications such as DC/DC converter feedback loops and USB data line protection.
Can BAT54BR RFG replace BAT54CD RFG in the same PCB layout?
No - BAT54CD RFG uses a common-anode configuration (anodes tied together), while BAT54BR RFG uses common-cathode (cathodes tied). Swapping them without schematic and layout revision would invert clamping polarity and likely cause functional failure. Their marking codes (KL7 vs KLB) and internal connectivity differ fundamentally.
Is BAT54BR RFG suitable for automotive under-hood applications?
Yes, BAT54BR RFG is qualified for junction temperatures from –65°C to +150°C and meets JESD201 Class 1A whisker resistance. Its SOT-363 package and Schottky characteristics make it appropriate for non-safety-critical under-hood modules like body control units and sensor interfaces - provided system-level thermal design maintains TJ within limits.
