Product details
Overview
BAT54AW RFG from Taiwan Semiconductor is a 30 V, 200 mA Schottky barrier diode in SOT-323 package, featuring ultra-high-speed switching (trr ≤ 5 ns), low forward voltage (VF ≤ 500 mV at IF = 30 mA), and reverse current ≤ 2 µA at VR = 25 V; used for voltage clamping and reverse polarity protection in portable power management circuits.
For engineers reviewing the BAT54AW RFG datasheet, BAT54AW RFG pinout, BAT54AW RFG application, or BAT54AW RFG equivalent, key selection criteria include reverse recovery time, forward voltage at operating current, junction capacitance (10 pF at 1 V), thermal resistance (625 °C/W), and RoHS/halogen-free compliance per IEC 61249-2-21.
Technical Context
This Schottky diode operates with metal–semiconductor junction architecture to eliminate minority-carrier storage delay, enabling sub-5 ns reverse recovery. Its low VF and low CJ support high-efficiency, high-frequency rectification and signal clamping in space-constrained layouts.
The SOT-323 package supports reflow soldering up to 260 °C/10 s and meets J-STD-020 moisture sensitivity level 1. Thermal performance is defined by RθJA = 625 °C/W, limiting continuous power dissipation to 200 mW at TA = 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse voltage before breakdown; sets clamping ceiling in protection circuits. |
| IF | 200 mA - Continuous forward current rating; defines steady-state conduction capability. |
| trr | 5 ns - Reverse recovery time; enables operation in >100 MHz switching applications without tail current loss. |
| VF @ 30 mA | ≤ 500 mV - Forward voltage drop; minimizes conduction loss in low-voltage rail clamping. |
| CJ @ 1 V | 10 pF - Junction capacitance; limits high-frequency signal distortion in RF detector or sampling circuits. |
| IR @ 25 V | ≤ 2 µA - Reverse leakage current; ensures low standby power in battery-backed systems. |
| RθJA | 625 °C/W - Junction-to-ambient thermal resistance; requires derating above 25 °C ambient for safe 200 mW operation. |
Pinout & Package
Package: SOT-323 - 3-terminal surface-mount plastic package, 5.00 mg weight, JEDEC-compliant outline, suitable for automated placement and IR/reflow assembly.

| Collector / Heat Slug (Pin 3) | Thermal path and mechanical anchor | Internally tied to cathode in BAT54AW RFG; provides primary heat dissipation path to PCB copper. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54AWT1G | Same VRRM (30 V), IF (200 mA), and SOT-323 package; VF slightly higher (≤550 mV @ 30 mA); trr = 6 ns. | Marginally slower recovery limits use in >80 MHz RF detectors vs. BAT54AW RFG. | Select when legacy sourcing or dual-sourcing across ON Semi and TSC is required. |
| BAT54CWS-7-F | Identical electrical specs and SOT-323 package; marked "L43" per TSC's own ordering table; same halogen-free construction. | No functional difference; differs only in tape-and-reel packaging (7" vs. 13" reel) and traceability marking. | Preferred for volume builds requiring Diodes Inc. supply chain continuity. |
Compared with SBAT54AWT1G and BAT54CWS-7-F, BAT54AW RFG offers the lowest measured trr (5 ns) and tightest VF distribution at 30 mA, making it optimal for high-frequency clamping and low-drop OR'ing where timing precision and conduction loss are critical.

FAQ
What is the maximum reverse voltage rating for BAT54AW RFG?
The BAT54AW RFG has a repetitive peak reverse voltage (VRRM) rating of 30 V. This means it can block up to 30 V in reverse bias without breakdown under normal operating conditions. Exceeding this voltage risks irreversible avalanche failure. The rating is validated per Taiwan Semiconductor's D2102 datasheet revision and applies across the full operating temperature range of –55 °C to +125 °C junction temperature.
Does BAT54AW RFG support lead-free reflow soldering?
Yes, BAT54AW RFG is qualified for lead-free reflow soldering at 260 °C for 10 seconds, per J-STD-020. Its package construction and die attach materials withstand this thermal profile without parametric shift or delamination. The device carries MSL Level 1 classification, meaning it may be stored indefinitely at ≤30 °C/60 % RH without baking prior to assembly.
What is the typical reverse recovery time of BAT54AW RFG?
The typical reverse recovery time (trr) of BAT54AW RFG is 5 ns, measured under IF = 10 mA, IR = 10 mA to 1 mA, and RL = 100 Ω. This value is confirmed in the Electrical Specifications table of the official Taiwan Semiconductor datasheet (Version D2102). It reflects the diode's ultra-fast switching behavior due to its Schottky barrier structure, which eliminates minority-carrier storage delay.
How does the forward voltage of BAT54AW RFG vary with current?
BAT54AW RFG exhibits a forward voltage (VF) of ≤240 mV at IF = 0.1 mA, ≤320 mV at 1.0 mA, ≤400 mV at 10 mA, ≤500 mV at 30 mA, and ≤1000 mV at 100 mA. These values are specified in the datasheet's Electrical Specifications table and reflect the diode's low-loss conduction characteristic across its rated current range, critical for minimizing voltage drop in low-voltage protection paths.
Is BAT54AW RFG halogen-free and RoHS compliant?
Yes, BAT54AW RFG is both halogen-free per IEC 61249-2-21 and RoHS compliant per EU Directive 2011/65/EU. The "G" suffix in the ordering code explicitly denotes green compound usage. Compliance is verified through material declarations and third-party testing, and applies to all units shipped under this part number.
