Product details
Overview
BAT30-09P6FILM from STMicroelectronics is a dual Schottky diode in SOT-666 package configured as opposite (anti-parallel) diodes, rated for 30 V reverse voltage and 300 mA continuous forward current per diode, with typical junction capacitance of 14 pF at 1 V and low forward voltage drop of 530 mV at 300 mA - optimized for high-frequency switching in DC-DC converter output rectification and polarity protection circuits.
For engineers reviewing the BAT30-09P6FILM datasheet, BAT30-09P6FILM pinout, BAT30-09P6FILM application, or BAT30-09P6FILM equivalent, key selection criteria include anti-parallel configuration suitability for bidirectional clamping, thermal resistance of 600 °C/W (junction-to-ambient, epoxy PCB), and leakage current ≤5 µA at 30 V reverse bias - critical for low-power standby and precision signal path protection.
Technical Context
This device integrates two independent Schottky diodes in a single SOT-666 surface-mount package with terminals arranged for opposite (anti-parallel) connection - enabling symmetrical voltage clamping in both polarities without external wiring. Its low 300 mA IF rating and 150 °C max junction temperature support operation in thermally constrained space-limited designs.
Dynamic performance is defined by negligible reverse recovery time (Schottky barrier), 14 pF typical capacitance at VR = 1 V, and forward voltage ranging from 240 mV (IF = 0.1 mA) to 530 mV (IF = 300 mA) - making it suitable for <1 MHz switching applications where conduction loss minimization outweighs ultra-high-speed requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - maximum repetitive reverse voltage before breakdown; sets clamping threshold in bidirectional protection circuits |
| IF (cont.) | 300 mA per diode - continuous forward current handling capacity; defines usable load current in low-power rectifier or clamp roles |
| C (typ., VR=1 V) | 14 pF - junction capacitance at low reverse bias; determines high-frequency impedance and signal integrity impact in RF or fast-switching paths |
| VF (IF=300 mA) | 530 mV - forward voltage drop at rated current; directly impacts conduction loss and thermal rise in power path applications |
| IR (VR=30 V, Tj=25°C) | ≤5 µA - reverse leakage current at full rated voltage; critical for battery-powered systems requiring ultra-low standby drain |
| Rth(j-a) | 600 °C/W - junction-to-ambient thermal resistance on FR4 PCB; governs allowable power dissipation and board layout cooling requirements |
| Tj (max) | 150 °C - maximum operating junction temperature; constrains ambient operating range and derating curves in enclosed environments |
Pinout & Package
SOT-666 is a 6-pin, dual-row, surface-mount plastic package measuring 1.5–1.7 mm × 1.5–1.7 mm × 0.45–0.60 mm height, with gull-wing leads and UL94 V0 compliant epoxy. Pin 1 and Pin 4 are anode terminals; Pin 2 and Pin 5 are cathode terminals - configured to support opposite (anti-parallel) diode orientation across Pins 1–2 and 4–5.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Input terminal for forward conduction in first polarity; connects to protected node or switching node in clamp topology |
| Pin 2 | Cathode of Diode 1 | Return path for Diode 1; tied to reference rail (e.g., GND or VCC) in unidirectional clamp or bidirectional pair |
| Pin 3 | Exposed pad / thermal slug | Non-electrical thermal interface; must be soldered to copper pour for effective heat dissipation (Rth(j-a) assumes this) |
| Pin 4 | Anode of Diode 2 | Input terminal for forward conduction in opposite polarity; enables symmetrical clamping when paired with Pin 2 |
| Pin 5 | Cathode of Diode 2 | Return path for Diode 2; completes anti-parallel configuration with Pin 1–Pin 2 for bidirectional voltage limiting |
| Pin 6 | No connect (NC) | Unused terminal; left floating or grounded per layout best practice - no internal connection to die |
Key Features
| Feature | Design Value |
|---|---|
| Opposite (anti-parallel) diode configuration | Enables bidirectional transient voltage suppression and AC signal clamping without discrete pairing or routing complexity |
| Low VF (530 mV @ 300 mA) | Reduces forward conduction loss by >30% vs. standard silicon diodes, improving efficiency in low-voltage DC-DC outputs |
| Ultra-low leakage (≤5 µA @ 30 V) | Minimizes quiescent current in always-on protection circuits, extending battery life in portable and IoT edge devices |
| 14 pF junction capacitance (VR = 1 V) | Preserves signal integrity up to ~100 MHz in data line protection, avoiding excessive RC filtering or timing skew |
| SOT-666 package with thermal pad | Supports 600 °C/W thermal resistance on standard FR4 - enables higher power density than SOD-323/SOD-523 alternatives |
Applications
| USB Port Polarity Protection | DC-DC Converter Output Clamp |
|---|---|
|
Use Scenario: Preventing damage from reversed USB cable insertion in host or peripheral ports. IC Role / Device Role / Timing Role: Anti-parallel Schottky clamp between VBUS and GND, conducting only during reverse-connection fault. Use Value: Blocks reverse current while adding <100 mΩ effective series resistance - avoids fuse blowout and maintains port compliance. |
Use Scenario: Suppressing flyback voltage spikes at synchronous buck converter output during MOSFET turn-off. IC Role / Device Role / Timing Role: Bidirectional clamp across LC filter output, absorbing energy from inductive kickback in both directions. Use Value: Limits overshoot to ≤33 V (30 V + VF) without snubber losses, preserving output regulation and MOSFET SOA. |
| RS-485 Transceiver ESD Clamp | Low-Power Sensor Signal Conditioning |
|
Use Scenario: Protecting differential RS-485 bus lines (A/B) against ±8 kV contact ESD per IEC 61000-4-2. IC Role / Device Role / Timing Role: Paired anti-parallel diodes shunting A–GND and B–GND, clamping transients before transceiver input stages. Use Value: Adds <14 pF capacitance per line - within RS-485 capacitance budget (<50 pF), maintaining 10 Mbps timing margins. |
Use Scenario: Biasing and protecting analog sensor outputs (e.g., thermistor, RTD bridges) in battery-powered condition monitoring nodes. IC Role / Device Role / Timing Role: Dual clamp limiting sensor node voltage to ±0.5 V beyond supply rails, preventing op-amp input stage saturation. Use Value: Leakage ≤5 µA ensures <0.1% error in 100 kΩ bridge arms - critical for 16-bit ADC accuracy without calibration overhead. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar anti-parallel Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSR0330P2T5G | Single SOT-23 dual-diode (common cathode), 30 V/300 mA, C = 22 pF @ 0 V | Lacks opposite configuration - requires external routing for anti-parallel use; higher capacitance limits HF bandwidth | Prefer when board space allows discrete placement and 22 pF is acceptable for <50 MHz signals |
| DMN3020LFG-7 | 30 V dual N-MOSFET in SOT-23-6, used as active rectifier; RDS(on) = 200 mΩ, no body diode asymmetry | Active solution with gate control - enables synchronous rectification but adds control complexity and BOM count | Choose only when >90% efficiency at light loads justifies added gate drive circuitry and cost |
Compared with NSR0330P2T5G and DMN3020LFG-7, BAT30-09P6FILM delivers integrated anti-parallel functionality in minimal footprint with lowest VF and leakage - ideal for passive, space-constrained clamping where simplicity and standby current matter most.

FAQ
What is the electrical configuration of BAT30-09P6FILM?
BAT30-09P6FILM contains two independent Schottky diodes wired in opposite (anti-parallel) orientation: Pin 1→Pin 2 forms Diode 1, and Pin 4→Pin 5 forms Diode 2, with Pin 3 as thermal pad and Pin 6 unconnected. This enables bidirectional clamping without external interconnects.
Can BAT30-09P6FILM replace BAT30-07P6FILM in a design?
No - BAT30-07P6FILM is configured as two parallel diodes (anodes tied, cathodes tied), while BAT30-09P6FILM is opposite (anode–cathode cross-connected). Substitution would invert clamping behavior and risk short-circuit failure; PCB layout and schematic must match the specific configuration code.
What is the maximum power dissipation at 25°C ambient?
Using Rth(j-a) = 600 °C/W and Tj(max) = 150 °C, maximum allowable power dissipation is (150 − 25) / 600 = 0.208 W. At 300 mA and 530 mV VF, actual dissipation is 0.159 W - within safe margin, assuming adequate PCB copper area under Pin 3.
Is BAT30-09P6FILM suitable for automotive applications?
BAT30-09P6FILM is not specified as automotive-grade (AEC-Q101 qualified) in ST's documentation. While its 150 °C Tj(max) and industrial temperature range support under-hood proximity use, ST explicitly states non-automotive parts are used in automotive applications at user's own risk - qualification testing is required for safety-critical systems.
