Product details
Overview
BAT54AD 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 1.00 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 BAT54AD RFG datasheet, BAT54AD RFG pinout, BAT54AD RFG application, or BAT54AD RFG equivalent, key selection criteria include low VF at low-to-moderate IF, fast trr for switching efficiency, dual-diode configuration in ultra-small SOT-363, thermal resistance of 625°C/W, and RoHS/halogen-free compliance for consumer and industrial PCBs.
Technical Context
The BAT54AD RFG integrates two independent Schottky diodes sharing a common cathode (anode-cathode-anode configuration), enabling bidirectional clamping or dual-path reverse polarity protection without external wiring. Its junction capacitance of ≤10 pF at 1 V reverse bias supports RF-adjacent signal routing.
Designed for surface-mount assembly per J-STD-002, it meets JESD201 Class 1A whisker resistance and UL 94V-0 flammability. The 6.99 mg mass and level-1 moisture sensitivity allow standard reflow without baking.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2016LFG-7 | Single-channel, 200 mA, 20 V VRRM, SOT-563 package; lower VF (0.35 V @ 100 mA) but reduced voltage margin | Limited to ≤20 V systems; unsuitable for 24 V industrial inputs | Select when lowest conduction loss is critical and voltage headroom permits |
| NSR0230P2T5G | Dual anode-common cathode, 30 V VRRM, 200 mA IF, SOT-363; VF = 0.45 V @ 100 mA, trr = 1.5 ns | Faster switching and lower VF, but higher cost and tighter IR spec (≤0.5 μA) | Prefer for high-frequency (>50 MHz) clamping where trr and VF trade-offs favor performance over cost |
Compared with DMN2016LFG-7 and NSR0230P2T5G, the BAT54AD RFG offers balanced voltage rating, thermal robustness (150°C TJ max), and cost-effective dual-diode integration in standard SOT-363-making it optimal for general-purpose 24 V industrial and consumer power protection where 5 ns trr and 1.00 V VF meet design margins.

FAQ
What is the pin configuration of the BAT54AD RFG?
The BAT54AD RFG uses a SOT-363 package with six terminals: Pins 1 and 3 are anodes of two independent Schottky diodes; Pins 2 and 5 are tied internally to the common cathode; Pins 4 and 6 are no-connect. This anode-cathode-anode arrangement supports dual-path clamping or redundancy without external wiring.
Does the BAT54AD RFG support reflow soldering without baking?
Yes, the BAT54AD RFG has moisture sensitivity level (MSL) 1 per J-STD-020, meaning it can be subjected to standard lead-free reflow profiles without prior baking. Its matte tin-plated leads comply with J-STD-002 for solderability, and the UL 94V-0 molding compound withstands peak temperatures up to 260°C.
What is the maximum junction temperature for the BAT54AD RFG?
The BAT54AD RFG has a specified junction temperature range of –65°C to +150°C. At TA = 25°C, its thermal resistance RθJA is 625°C/W; derating begins above 25°C ambient, with full power dissipation (200 mW) permitted only below 75°C ambient per the power derating curve in the datasheet.
How does the BAT54AD RFG compare to the BAT54CD RFG in terms of marking and internal structure?
The BAT54AD RFG is marked "KL6" and features a dual-anode/common-cathode configuration. In contrast, the BAT54CD RFG is marked "KL7" and implements a common-anode/dual-cathode topology. These structural differences affect circuit implementation-BAT54AD RFG is suited for bidirectional clamping to ground, while BAT54CD RFG serves dual-rail referencing applications.
Is the BAT54AD RFG suitable for reverse polarity protection in 24 V automotive systems?
Yes, the BAT54AD RFG supports 30 V VRRM and operates up to 150°C junction temperature, making it suitable for reverse polarity protection in 12 V and 24 V automotive body control modules. Its 1.00 V VF at 100 mA limits power loss, and its 2 μA IR at 25 V ensures minimal standby drain on battery-backed circuits.
