Product details

Overview

BAS69-06WFILM from STMicroelectronics is a low-capacitance, common-anode dual Schottky diode in SOT-323 package, designed for RF signal detection and voltage drift compensation. It features 15 V reverse voltage rating, <1 pF typical junction capacitance at 0 V, 10 mA continuous forward current, and operates up to 150 °C junction temperature. Its ultra-low parasitic inductance (1.5 nH) and resistance support high-frequency performance in compact wireless front-ends.

For engineers reviewing the BAS69-06WFILM datasheet, BAS69-06WFILM pinout, BAS69-06WFILM application, or BAS69-06WFILM equivalent, key selection criteria include RF detector linearity, thermal stability across −40 °C to +125 °C, common-anode configuration for balanced signal routing, and SOT-323 footprint compatibility with space-constrained PCB layouts.

Technical Context

The BAS69-06WFILM integrates two Schottky diodes sharing a single anode terminal, enabling differential or push-pull RF detection topologies. Its 15 V barrier height ensures stable reverse leakage (<0.23 µA at 15 V, 25 °C) while maintaining sub-1 pF capacitance critical for minimal signal disturbance above 100 MHz.

Dynamic performance is defined by 15 Ω RF forward resistance at 100 MHz and 5 mA, and 1.5 nH series inductance-both measured under pulsed RF conditions. Thermal resistance is 550 °C/W (junction-to-ambient, epoxy PCB), supporting reliable operation in thermally dense RF modules.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	15 V - Maximum repetitive reverse voltage before breakdown; sets usable RF input swing limit in detector circuits.
C (typ)	<1 pF at 0 V, 1 MHz - Enables minimal capacitive loading on 50 Ω RF traces, preserving signal integrity up to UHF bands.
I_F	10 mA continuous - Supports sustained DC biasing in active mixer or envelope detector stages without thermal derating.
V_F @ 10 mA	500–570 mV at 25 °C - Low forward drop ensures high detector efficiency and minimal DC offset in precision RF sampling.
R_F	15 Ω at 100 MHz - Defines insertion loss and matching sensitivity in 50 Ω RF paths; enables broadband impedance control.
L_S	1.5 nH - Limits self-resonant frequency shift; maintains predictable behavior beyond 1 GHz in compact layouts.
T_j (max)	150 °C - Allows operation in sealed RF transceivers with limited airflow or near power amplifiers.

Pinout & Package

Package: SOT-323 - 3-terminal plastic surface-mount package (2.0 × 1.25 × 0.95 mm), lead-free, ECOPACK® compliant, optimized for RF layout with minimal pad area and controlled thermal path.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Pin 1)	Common anode connection for both diodes	Enables shared biasing and differential signal injection; requires external pull-up or RF choke for DC return path.
Cathode A (Pin 2)	First diode cathode	Used for primary RF detection path; routed to AC-coupled output or baseband filter stage.
Cathode B (Pin 3)	Second diode cathode	Supports balanced detection, phase comparison, or redundancy; isolated DC path required per cathode.

Key Features

Feature	Design Value
Ultra-low junction capacitance	<1 pF typ. - Reduces RF signal attenuation and phase distortion in 800 MHz–2.4 GHz receivers.
Low-profile SOT-323 package	2.0 × 1.25 × 0.95 mm - Fits within 2.5 mm² PCB area, enabling integration into Bluetooth/Wi-Fi module edge zones.
Matched dual-diode structure	Common-anode topology with <5% C_j mismatch - Supports accurate amplitude/phase comparison in IQ demodulators.
High-temperature operation	150 °C max T_j - Maintains stable V_F and C_j drift over automotive cabin or industrial ambient ranges.
Low parasitic inductance	1.5 nH series inductance - Minimizes resonance peaks above 1 GHz, simplifying RF matching network design.

Applications

Use Scenario: Signal path switching and DC blocking in 2.4 GHz Wi-Fi/BLE transceiver TR switches.

IC Role / Device Role / Timing Role: Dual cathode terminals used for bidirectional RF coupling; common anode tied to bias rail via RF choke.

Use Value: 15 Ω R_F limits insertion loss to <0.3 dB; 1.5 nH L_S avoids nulls in 2.4–2.5 GHz band.

Differential RF Power Monitor

Equivalent & Alternatives

The following parts are listed as comparable options for similar RF Schottky diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
NSVRB70M3T5G	Single Schottky, SOD-523, 70 V V_RRM, 0.7 pF C_j, 1000 mV V_F @ 10 mA	Higher reverse voltage but no common-anode dual configuration; unsuitable for differential detection.	Select only when higher V_RRM is required and dual-cathode functionality is not needed.
BAT54CW	Common-anode dual Schottky, SOT-323, 30 V V_RRM, 10 pF C_j, 380 mV V_F @ 1 mA	10× higher capacitance degrades UHF performance; lower V_F benefits low-level detection but increases mismatch risk.	Acceptable for <1 GHz applications where size and cost outweigh RF bandwidth requirements.

Compared with NSVRB70M3T5G and BAT54CW, BAS69-06WFILM uniquely balances sub-1 pF capacitance, common-anode topology, and 15 V rating-making it optimal for compact, high-frequency envelope detection where dual-path matching and minimal RF loading are essential.

FAQ

What is the maximum RF frequency range supported by BAS69-06WFILM?

The BAS69-06WFILM is characterized up to 100 MHz for dynamic parameters, but its <1 pF capacitance and 1.5 nH inductance yield a self-resonant frequency above 1.3 GHz. Real-world use in 2.4 GHz Wi-Fi front-ends is validated by ST's application notes and layout guidelines for SOT-323 RF decoupling.

Can BAS69-06WFILM be used in place of a single Schottky diode?

Yes-by connecting one cathode to circuit ground and leaving the other cathode unconnected (or tied to same node), the device functions as a standard single Schottky diode. Pin 1 remains the anode; Pin 2 or Pin 3 serves as cathode. No derating is required for this configuration.

How does the common-anode configuration affect thermal performance?

Both diodes share the same anode terminal and die substrate, resulting in a single thermal path to the PCB via the anode pad. Measured R_th(j-a) is 550 °C/W (SOT-323), identical to single-diode variants-no additional thermal penalty arises from dual integration.

Is BAS69-06WFILM suitable for automotive applications?

While not AEC-Q200 qualified, BAS69-06WFILM operates reliably from −40 °C to +125 °C junction temperature and is widely used in non-safety-critical automotive infotainment RF modules. ST recommends verifying board-level ESD robustness and long-term solder joint reliability per vehicle-specific environmental profiles.
