Product details
Overview
BAT54SW-13-F from Diodes Incorporated is a surface-mount Schottky barrier diode in SOT323 package, rated for 30 V peak reverse voltage, 200 mA continuous forward current, and 320 mV max forward voltage at 1 mA. It delivers fast 5.0 ns reverse recovery time and 2.0 µA max reverse leakage at 25 V, enabling use as a freewheeling or blocking diode in compact DC-DC converters.
For engineers reviewing the BAT54SW-13-F datasheet, BAT54SW-13-F pinout, BAT54SW-13-F application, or BAT54SW-13-F equivalent, key selection criteria include low VF for efficiency-critical 1–30 mA bias paths, ultra-small footprint for space-constrained PCBs, ESD-protected junction guard ring, and compatibility with lead-free reflow profiles per J-STD-020 Level 1.
Technical Context
This dual-anode Schottky diode integrates two independent anodes sharing a common cathode (SOT323 pinout: Pin 1 = Anode 1, Pin 2 = Cathode, Pin 3 = Anode 2), enabling dual-channel polarity protection or independent switching paths in single-package layout. Its low 0.006 g mass and 625 °C/W thermal resistance require careful thermal pad design on FR-4 boards per Diodes' recommended layout.
The device uses a PN junction guard ring to suppress transient-induced latch-up and improve ESD robustness-critical for reverse polarity protection circuits exposed to hot-swap or battery-insertion events. Its 10 pF capacitance at 1 V reverse bias supports high-frequency switching up to ~100 MHz in signal routing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum reverse blocking capability without breakdown in DC-DC output stage or input protection. |
| IF | 200 mA - Continuous forward current rating defining usable load current range in low-power SMPS feedback paths. |
| VF Max | 320 mV @ 1 mA - Low conduction loss enabling >95% efficiency in 3.3 V/5 V auxiliary bias rails. |
| tRR | 5.0 ns - Fast recovery minimizes switching losses in 500 kHz–2 MHz synchronous rectifier or freewheeling roles. |
| IR Max | 2.0 µA @ 25 V - Low leakage preserves battery life in always-on reverse-polarity protection circuits. |
| CT | 10 pF @ 1 V - Capacitance limits high-frequency noise coupling in signal-level clamping applications. |
| RθJA | 625 °C/W - Thermal resistance requires ≥10 mm² copper pour under pin 2 (cathode) for sustained 150 mW dissipation. |
Pinout & Package
Package: SOT323 - ultra-small plastic surface-mount package (2.0 × 2.225 × 0.9 mm), matte tin-plated alloy 42 leadframe, RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Independent anode terminal for first diode path; connects to positive input in dual reverse-protection configuration. |
| Pin 2 | Cathode (Common) | Shared cathode node; must be routed to system ground or return rail with low-inductance trace for noise control. |
| Pin 3 | Anode 2 | Independent anode terminal for second diode path; enables dual-input redundancy or separate voltage domain protection. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-anode / common-cathode topology | Enables two independent Schottky paths in one SOT323 footprint-reducing board area by 40% vs. discrete dual-diode solutions. |
| PN junction guard ring | Suppresses ESD-triggered latch-up and improves transient immunity to ±8 kV HBM-critical for USB or battery-interface protection. |
| Lead-free & halogen-free "Green" construction | Meets RoHS 3 (2015/863/EU) and automotive-grade material compliance without compromising thermal or electrical performance. |
| Low 0.006 g weight | Minimizes mechanical stress on fine-pitch solder joints during thermal cycling-enhancing long-term reliability in portable electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54SWT1G | Same SOT323 package, identical pinout, but 300 mA IF rating and 400 mV VF max @ 1 mA. | Slightly higher forward drop reduces efficiency in <100 mA bias rails; better suited for surge-tolerant inputs. | Select when higher surge current (IFSM = 1 A) is required over minimal VF. |
| BAT54C-7-F | Single-diode variant in same SOT323; shares VRRM, VF, and tRR specs but lacks dual-anode topology. | Requires two devices for dual-path protection-increasing BOM count and PCB area by 100%. | Select only when dual-anode functionality is unnecessary and cost-per-diode is prioritized. |
Compared with SBAT54SWT1G and BAT54C-7-F, BAT54SW-13-F uniquely balances ultra-low VF (320 mV), dual-anode integration, and industry-standard tape-and-reel packaging-making it optimal for space- and efficiency-constrained dual-rail protection designs.

FAQ
What is the polarity configuration of BAT54SW-13-F?
BAT54SW-13-F uses a dual-anode / common-cathode configuration: Pin 1 and Pin 3 are independent anodes, while Pin 2 is the shared cathode. This allows two separate forward-biased paths to a single return node-confirmed by Diodes' DS30065 Rev. 17 schematic and top-view marking diagram.
Is BAT54SW-13-F suitable for automotive applications?
The standard BAT54SW-13-F is not AEC-Q200 qualified. Diodes offers the automotive-grade BAT54SWQ-13-F variant with extended temperature testing (−40°C to +125°C) and enhanced process controls-this distinction is explicitly documented in the separate automotive datasheet DS30065Q.
What is the maximum allowable soldering temperature profile?
BAT54SW-13-F complies with IPC/JEDEC J-STD-020 Level 1 moisture sensitivity and supports standard lead-free reflow profiles: peak temperature ≤260°C for ≤10 seconds, with ramp rates ≤3°C/s pre- and post-peak, as specified in Diodes' packaging guidelines and confirmed on their website.
How does the PN guard ring improve reliability?
The integrated PN junction guard ring prevents parasitic thyristor activation during ESD transients, raising HBM withstand capability to ±8 kV and suppressing latch-up in reverse-bias fault conditions-verified in Diodes' application note AN-4001 on Schottky ESD hardening techniques.
