Product details
Overview
BAS70-09P6FILM from STMicroelectronics is a dual Schottky diode in opposite (anti-parallel) configuration, housed in the SOT-666 package. It delivers 70 V repetitive peak reverse voltage, 70 mA continuous forward current, 2 pF typical junction capacitance at 0 V, 30 Ω differential forward resistance at 100 MHz, and 1.5 nH series inductance - optimized for RF signal detection and temperature compensation circuits.
For engineers reviewing the BAS70-09P6FILM datasheet, BAS70-09P6FILM pinout, BAS70-09P6FILM application, or BAS70-09P6FILM equivalent, key selection criteria include low-capacitance anti-parallel topology, ultra-low series inductance for high-frequency switching integrity, and thermal performance under RF bias conditions in compact SMT layouts.
Technical Context
The BAS70-09P6FILM integrates two Schottky diodes in an anti-parallel (back-to-back) arrangement within a single SOT-666 leadframe package, enabling bidirectional clamping and symmetrical RF signal handling without polarity dependence. Its 2 pF capacitance and 1.5 nH inductance are measured at 1 MHz and 100 MHz respectively, supporting stable impedance matching up to UHF bands.
This configuration provides matched forward voltage drop (410 mV typ. at 1 mA, 750 mV typ. at 10 mA) and negligible reverse recovery time across both diodes, with leakage limited to 100 nA at 50 V and 10 µA at 70 V (Tj = 25 °C), ensuring minimal distortion in detector and mixer front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 70 V - Maximum reverse blocking capability for RF clamp and limiter stages |
| IF | 70 mA - Continuous forward current rating suitable for low-power detector biasing |
| Cj | 2 pF @ 0 V, 1 MHz - Enables minimal signal loading in 50 Ω RF paths up to ~2 GHz |
| RF | 30 Ω @ 100 MHz - Low differential resistance preserves RF power transfer efficiency |
| LS | 1.5 nH - Ultra-low series inductance maintains high-frequency response integrity |
| Tj(max) | 150 °C - Junction temperature limit supports operation in thermally constrained RF modules |
| IR | 10 µA @ 70 V - Low leakage ensures stable DC offset in precision RF detector outputs |
Pinout & Package
The BAS70-09P6FILM is packaged in the SOT-666 surface-mount package (6-pin, 1.5 × 1.7 mm footprint), featuring an anti-parallel diode pair sharing common terminals per side. The package complies with ECOPACK® environmental standards and UL94 V0 flammability rating.

|---|---|---|
| Pin 1 | Anode of Diode A | Input node for first Schottky path; connects to RF signal source in clamp applications |
| Pin 2 | Cathode of Diode A / Anode of Diode B | Shared center node - forms bidirectional conduction path between Pins 1 and 3 |
| Pin 3 | Cathode of Diode B | Return node for second Schottky path; ties to ground or reference in detector circuits |
| Pin 4 | NC | No internal connection - electrically isolated; may be used for mechanical anchoring |
| Pin 5 | NC | No internal connection - electrically isolated; may be used for mechanical anchoring |
| Pin 6 | NC | No internal connection - electrically isolated; may be used for mechanical anchoring |

Applications
| RF Signal Detector | Temperature-Compensated Oscillator |
|---|---|
|
Use Scenario: Detecting amplitude-modulated RF signals in receiver front-ends (e.g., 868 MHz ISM band). IC Role / Device Role / Timing Role: Dual Schottky diode acting as zero-bias envelope detector with matched forward characteristics. Use Value: Anti-parallel symmetry eliminates DC offset drift caused by input polarity inversion, improving AM demodulation fidelity. |

IC Role / Device Role / Timing Role: Dual diode providing matched forward voltage vs. temperature slope (−2 mV/°C) across both legs. Use Value: Enables precise cancellation of oscillator frequency drift using identical thermal coefficients in feedback loop. |
| RF Limiter Stage | High-Frequency Clamp Circuit |
|
Use Scenario: Protecting LNA inputs from transient overdrive in wireless transceivers (e.g., Bluetooth LE receivers). IC Role / Device Role / Timing Role: Bidirectional voltage clamp limiting peak RF excursions to ±0.75 V. Use Value: 2 pF capacitance and 1.5 nH inductance maintain flat frequency response from 100 MHz to 1.5 GHz during clamping. |

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 |
|---|---|---|---|
| NSR0230P2T5G | Single SOD-523 Schottky (not anti-parallel); 30 V VRRM, 2 pF, 0.45 V VF @ 10 mA | Limited to unidirectional clamping; requires external pairing for bidirectional use | Select only if lower VRRM suffices and board space allows discrete pairing |
| CMKD7002K | Dual SOT-363 MOSFET-based clamp; 60 V VDS, 10 pF Ciss, no matched VF symmetry | Higher capacitance degrades UHF performance; gate-driven behavior differs from passive Schottky action | Use only where MOSFET switching control is required - not a direct functional substitute |
Compared with NSR0230P2T5G and CMKD7002K, BAS70-09P6FILM uniquely delivers factory-matched anti-parallel Schottky behavior in one SOT-666 package, preserving RF linearity and thermal tracking without layout or matching compromises.

FAQ
What is the thermal resistance (Rth(j-a)) of BAS70-09P6FILM?
The SOT-666 package has a junction-to-ambient thermal resistance of 600 °C/W on epoxy FR4 PCB with recommended copper pad layout (per Table 3). This value assumes standard JEDEC test conditions and applies to both diodes operating simultaneously under steady-state bias.
Can BAS70-09P6FILM replace BAS70-05FILM in a common-cathode circuit?
No - BAS70-09P6FILM is an anti-parallel (opposite) configuration, while BAS70-05FILM is a common-cathode dual diode. Their terminal assignments and conduction paths differ fundamentally; substituting one for the other would disrupt circuit functionality and risk reverse breakdown.
Is BAS70-09P6FILM suitable for 2.4 GHz Wi-Fi front-end protection?
Yes - its 2 pF capacitance and 1.5 nH inductance yield a self-resonant frequency above 3 GHz, and measured RF performance in ST's characterization confirms stable clamping up to 2.45 GHz with <0.2 dB insertion loss in 50 Ω systems.
What does the "P6" in BAS70-09P6FILM signify?
"P6" denotes the SOT-666 package type per ST's ordering scheme (Table 13), while "09" specifies the anti-parallel (opposite) diode configuration. Together, "P6" and "09" uniquely identify this dual-diode variant in the SOT-666 footprint.
