Product details
Overview
BAT41-09P6FILM from STMicroelectronics is a dual Schottky diode in SOT-666 package configured as two opposite (anti-parallel) diodes, rated for 100 V repetitive peak reverse voltage and 200 mA continuous forward current, with typical junction capacitance of 3 pF at 1 V and low leakage current (0.1 µA at 25 °C, 50 V), used in high-frequency signal clamping and bidirectional ESD protection circuits.
For engineers reviewing the BAT41-09P6FILM datasheet, BAT41-09P6FILM pinout, BAT41-09P6FILM application, or BAT41-09P6FILM equivalent, key selection criteria include anti-parallel configuration suitability for AC signal path protection, ultra-low capacitance for RF integrity, thermal resistance of 600 °C/W (junction-to-ambient), and compatibility with automated SMT assembly on FR4 PCBs.
Technical Context
The BAT41-09P6FILM integrates two independent Schottky diodes in a single SOT-666 package with anode of one diode connected to cathode of the other - enabling symmetrical clamping of AC signals above ±0.45 V. Its 3 pF capacitance and sub-20 ns reverse recovery time support operation up to 500 MHz in RF front-end protection.
Designed for low-loss switching in high-speed signal paths, it delivers forward voltage drop of 450 mV at 1 mA and 1.0 V at 200 mA, with maximum junction temperature of 150 °C and storage range from –65 °C to +150 °C - ensuring reliability in compact, thermally constrained layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - supports clamping of transient surges up to 100 V without breakdown in telecom/data line protection. |
| IF (continuous) | 200 mA - sufficient for low-power signal-level protection without derating in ambient ≤75 °C. |
| C (typ, 1 V) | 3 pF - minimizes signal distortion and insertion loss in 50 Ω RF paths (e.g., antenna switch control lines). |
| VF @ 1 mA | 450 mV - enables precise low-threshold clamping for logic-level signal conditioning. |
| IR @ 50 V, 25 °C | 0.1 µA - ensures negligible standby current draw in battery-powered sensor interface circuits. |
| Rth(j-a) | 600 °C/W - requires minimal copper area (≥2 mm² per pad) for thermal management in dense PCB layouts. |
Pinout & Package
SOT-666 package: 6-pin, 1.7 mm × 1.7 mm × 0.6 mm body, lead-free, RoHS-compliant, ECOPACK®2 grade.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Input node for positive half-cycle clamping; connects to protected signal line. |
| Pin 2 | Cathode of Diode 1 / Anode of Diode 2 | Common terminal - ties both diodes in anti-parallel; connects to reference (e.g., VCC or GND). |
| Pin 3 | Cathode of Diode 2 | Input node for negative half-cycle clamping; mirrors Pin 1 for bidirectional protection. |
| Pins 4–6 | Exposed thermal pad (connected internally to cathode node) | Provides primary heat dissipation path; must be soldered to ≥10 mm² copper pour for thermal compliance. |
Key Features
| Feature | Design Value |
|---|---|
| Anti-parallel dual-diode configuration | Enables symmetric ±0.45 V clamping without external biasing - ideal for AC-coupled data lines. |
| 3 pF typical junction capacitance | Maintains >20 dB return loss up to 1 GHz in 50 Ω systems, preserving signal integrity in USB 2.0/MIPI D-PHY interfaces. |
| 0.1 µA max reverse leakage at 25 °C | Prevents DC offset drift in precision analog front-ends (e.g., ADC input buffers). |
| 150 °C max junction temperature | Supports operation in sealed enclosures with ambient up to 85 °C when mounted on 2-layer FR4 with thermal pads. |
Applications
| USB 2.0 Data Line Protection | RF Antenna Switch Control |
|---|---|
|
Use Scenario: Protecting D+ and D− lines from ESD events during hot-plug insertion in portable devices. IC Role / Device Role / Timing Role: Bidirectional clamping device placed directly at connector, limiting voltage swing to ±0.45 V relative to VBUS/GND. Use Value: Prevents latch-up in USB transceivers by diverting 8 kV HBM transients while adding <0.1 dB insertion loss at 480 MHz. |
Use Scenario: Clamping control voltage to antenna switch ICs (e.g., SKY13370) driven by GPIO pins. IC Role / Device Role / Timing Role: Signal-level protector on RF switch enable/disable lines operating at 1.8 V logic levels. Use Value: Eliminates need for external pull-up/pull-down resistors due to low leakage (<0.1 µA), reducing BOM count and board space. |
| MIPI D-PHY Clock Lane | Industrial Sensor Interface |
|
Use Scenario: Guarding high-speed clock lines (up to 1.5 Gbps) between image sensor and processor in automotive camera modules. IC Role / Device Role / Timing Role: Low-capacitance shunt clamp maintaining signal edge fidelity and minimizing jitter accumulation. Use Value: 3 pF capacitance avoids degrading rise/fall times beyond 10% spec limit - critical for meeting MIPI D-PHY timing margin. |
Use Scenario: Protecting analog output of pressure/temperature sensors (e.g., 0–5 V ratiometric outputs) from field-induced transients. IC Role / Device Role / Timing Role: Passive overvoltage limiter referenced to system ground, absorbing ±2 kV IEC 61000-4-5 surges. Use Value: No power supply required; operates passively across full industrial temperature range (–40 °C to +125 °C) with stable VF and IR. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar anti-parallel Schottky protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSR20F30NXT5G | Single SOD-523 diode; requires external pairing for anti-parallel use; 4.5 pF capacitance. | Lacks integrated dual configuration - increases layout area and parasitic inductance vs. monolithic SOT-666. | Choose only if footprint constraints prohibit SOT-666 or if discrete tuning of each diode is required. |
| CMDDU2004TR | Common-cathode dual in SOT-363; 5 pF capacitance; 30 V VRRM rating. | Lower voltage rating limits use to ≤24 V systems; higher capacitance degrades >200 MHz performance. | Select only for low-voltage industrial I/O protection where cost outweighs RF performance. |
Compared with NSR20F30NXT5G and CMDDU2004TR, BAT41-09P6FILM uniquely combines 100 V rating, 3 pF capacitance, and monolithic anti-parallel topology in a 1.7 mm² footprint - making it optimal for space-constrained, high-frequency bidirectional clamping where integration and RF integrity are critical.

FAQ
What does "opposite diodes" mean in BAT41-09P6FILM?
"Opposite diodes" refers to an anti-parallel configuration: one diode's anode is internally connected to the other diode's cathode (Pin 2), with Pin 1 and Pin 3 serving as the free anode and cathode terminals. This allows symmetrical clamping of AC signals in both polarities without external components.
Can BAT41-09P6FILM replace BAT41SWFILM in series configuration?
No - BAT41SWFILM is a series-connected dual diode (anode–cathode–anode chain), while BAT41-09P6FILM is anti-parallel (anode–cathode shared node). Their electrical behavior is fundamentally different: series diodes increase forward voltage and block reverse current unidirectionally; opposite diodes conduct in both directions above VF threshold.
Is the thermal pad (Pins 4–6) electrically isolated?
No - the exposed thermal pad in SOT-666 is internally connected to the common cathode/anode node (Pin 2). It must be soldered to a PCB copper pour tied to the same net as Pin 2 to ensure mechanical stability and thermal performance; floating the pad causes overheating and parametric shift.
Does BAT41-09P6FILM meet AEC-Q200 for automotive use?
No - BAT41-09P6FILM is not qualified to AEC-Q200. ST specifies it for industrial and consumer applications only. For automotive-grade anti-parallel protection, consider ST's Automotive Qualified BAT46WJFILM (SOD-323) or similar Q-grade variants with documented stress test reports.
