Product details
Overview
BAT30AWFILM from STMicroelectronics is a 30 V, 300 mA common-anode dual Schottky diode in SOT-323 package, optimized for high-frequency switching and low-loss DC-DC converter freewheeling paths. It delivers 530 mV forward voltage at 300 mA (Tj = 25 °C), 14 pF capacitance at VR = 1 V, and operates up to 150 °C junction temperature - enabling compact, efficient power management in space-constrained portable electronics.
For engineers reviewing the BAT30AWFILM datasheet, BAT30AWFILM pinout, BAT30AWFILM application, or BAT30AWFILM equivalent, this device is selected for low-VF, fast-recovery discrete diode roles in synchronous rectification, OR-ing circuits, and reverse-polarity protection where dual-anode topology simplifies layout and reduces conduction loss versus single-diode solutions.
Technical Context
The BAT30AWFILM integrates two independent Schottky diodes sharing a common anode terminal, forming a dual-diode configuration ideal for bidirectional current routing or redundant path control. Its low 0.53 V forward drop at rated current and sub-10 ns reverse recovery time minimize switching losses in high-frequency (>1 MHz) converters.
Thermal performance is defined by Rth(j-a) = 550 °C/W on FR4 PCB with standard pad layout, and leakage remains below 1 µA at VR = 10 V and Tj = 25 °C - supporting stable operation in thermally demanding environments without thermal runaway risk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum reverse blocking voltage before breakdown; suitable for 24 V system rails with margin. |
| IF | 300 mA continuous - Sustained forward current capability without derating on standard PCB layout. |
| VF @ 300 mA | 530 mV typical - Low conduction loss enables >95% efficiency in 3.3–5 V buck converter output stages. |
| C @ VR = 1 V | 14 pF - Minimal capacitive loading on high-speed switching nodes; preserves signal integrity in RF bias networks. |
| IR @ VR = 10 V | <1 µA at 25 °C - Negligible reverse leakage ensures low standby power in battery-backed circuits. |
| Tj(max) | 150 °C - Enables operation in automotive under-hood or industrial motor-control ambient conditions. |
| Rth(j-a) | 550 °C/W - Predictable thermal rise of ~165 °C at full load; guides heatsinking decisions for sustained duty cycles. |
Pinout & Package
SOT-323 package: 3-pin surface-mount plastic case with gull-wing leads, 1.25 mm pitch, 2.0 mm × 1.25 mm footprint, and 0.95 mm height - compatible with standard reflow profiles and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode (common) | Shared anode connection for both diodes; ties to positive rail or switch node in OR-ing/freewheeling topologies. |
| Pin 2 | Cathode 1 | Independent cathode for first diode; routes current to load 1 or feedback path in dual-output regulators. |
| Pin 3 | Cathode 2 | Independent cathode for second diode; enables parallel-path redundancy or separate output regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Common-anode dual configuration | Reduces component count and PCB area vs. two discrete SOD-323 diodes; simplifies layout in dual-rail OR-ing. |
| Ultra-low VF (530 mV @ 300 mA) | Directly lowers I²R losses in high-current paths - critical for extending battery life in wearables and IoT sensors. |
| 14 pF junction capacitance | Minimizes AC coupling and ringing in fast-switching gate-drive or RF detector applications. |
| 150 °C max junction temperature | Supports uninterrupted operation in sealed enclosures or near heat-generating ICs without thermal shutdown. |
| Lead-free ECOPACK® packaging | Complies with RoHS and halogen-free requirements for global consumer and industrial product certifications. |
Applications
| USB Power Delivery Switching | Industrial Sensor Signal Conditioning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT30W-7-F | Same SOT-323 package and common-anode topology; VF = 550 mV @ 300 mA (higher by 20 mV); C = 16 pF @ 1 V. | Slightly higher conduction loss and capacitance; acceptable where 2% efficiency margin exists. | Select when sourcing flexibility is prioritized over minimal VF; identical footprint and solder profile. |
| NSR0330P2T5G | Common-anode dual in SOT-23; VF = 450 mV @ 300 mA (lower by 80 mV); Rth(j-a) = 500 °C/W; VRRM = 30 V. | Better thermal and conduction performance but larger SOT-23 footprint; requires PCB redesign. | Choose for higher-efficiency designs where board space permits larger package and thermal relief pads. |
Compared with SBAT30W-7-F, BAT30AWFILM offers lower VF and capacitance; compared with NSR0330P2T5G, it trades 80 mV VF increase for 30% smaller footprint and compatibility with ultra-compact layouts - making it optimal for wearable and hearing-aid-class devices.

FAQ
What is the maximum reverse voltage rating for BAT30AWFILM?
The BAT30AWFILM has a repetitive peak reverse voltage (VRRM) rating of 30 V, verified per Table 2 of STMicroelectronics Doc ID 12564 Rev 3. This rating applies across the full operating junction temperature range (−65 °C to +150 °C) and defines the maximum DC or peak AC voltage the diode can block without entering avalanche breakdown.
Can BAT30AWFILM be used in place of two separate BAT30WFILM diodes?
No - BAT30AWFILM is a common-anode dual diode, whereas BAT30WFILM is a single diode in the same SOT-323 package. Replacing two BAT30WFILM units would require external wiring to replicate the shared-anode topology, introducing parasitic inductance and compromising high-frequency performance. The BAT30AWFILM integrates that structure monolithically.
Is BAT30AWFILM suitable for automotive applications?
BAT30AWFILM is not qualified to AEC-Q101 and lacks automotive-grade screening or guaranteed operation beyond 125 °C ambient. While its 150 °C Tj(max) supports under-hood temperatures in some non-safety-critical subsystems, ST does not recommend or warrant its use in automotive safety or propulsion systems per their disclaimer in Doc ID 12564 Rev 3.
What is the thermal resistance from junction to ambient for BAT30AWFILM?
The junction-to-ambient thermal resistance (Rth(j-a)) for BAT30AWFILM in SOT-323 is 550 °C/W, measured on standard FR4 PCB with recommended copper pad layout per Table 3 of the datasheet. This value assumes 35 µm copper thickness and 2.25 mm² total pad area per lead, and decreases with added thermal vias or larger copper pours.
