Product details

Overview

BAS69-05WFILM from STMicroelectronics is a low-capacitance, common-cathode dual Schottky diode in SOT-323 package, designed for RF signal detection and voltage drift compensation in high-frequency circuits. 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.

For engineers reviewing the BAS69-05WFILM datasheet, BAS69-05WFILM pinout, BAS69-05WFILM application, or BAS69-05WFILM equivalent, key selection criteria include ultra-low capacitance for minimal RF signal disturbance, common-cathode configuration for balanced detector topologies, thermal performance in space-constrained layouts, and compatibility with 100 MHz–1 GHz RF front-end designs.

Technical Context

The BAS69-05WFILM integrates two identical Schottky diodes sharing a single cathode terminal, enabling differential or balanced RF detection without external node coupling. Its 15 V barrier height and sub-1 pF capacitance at 0 V reverse bias ensure minimal loading on tuned RF circuits.

Designed for operation up to 150 °C, it maintains stable forward voltage (500–570 mV at 10 mA, 25 °C) and low reverse leakage (<0.23 µA at 15 V, 25 °C), supporting reliable DC offset compensation across temperature in receiver front-ends and envelope detectors.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	15 V - Maximum repetitive reverse voltage before breakdown; sets usable RF swing range in detector applications.
C (typ)	<1 pF at 0 V, 1 MHz - Enables minimal capacitive loading on 100+ MHz RF nodes, preserving Q-factor of matching networks.
I_F	10 mA continuous - Supports sustained detector biasing without thermal runaway in compact SOT-323 footprint.
V_F	500–570 mV at I_F = 10 mA, 25 °C - Low forward drop ensures efficient rectification and minimal DC loss in signal path.
R_F	15 Ω at 100 MHz - Low RF series resistance minimizes insertion loss in high-frequency switching or mixing paths.
T_j(max)	150 °C - Allows operation in thermally dense RF modules without derating in ambient up to +85 °C.

Pinout & Package

Package: SOT-323 - 3-terminal surface-mount plastic package with 0.65 mm lead pitch, optimized for RF layout with low parasitic inductance (1.5 nH) and resistance.

Pin/Terminal	Circuit Role	Design Meaning
1 (Anode A)	First diode anode	Independent RF input node for one half of common-cathode pair; enables dual-path signal routing.
2 (Cathode)	Shared cathode	Common output/DC reference node; simplifies biasing and reduces PCB trace inductance in balanced detectors.
3 (Anode B)	Second diode anode	Independent RF input node for second diode; supports push-pull, differential, or dual-band detection schemes.

Key Features

Feature	Design Value
Ultra-low junction capacitance	<1 pF typ. at 0 V - Preserves impedance matching and bandwidth in UHF/VHF receiver front-ends.
Common-cathode dual configuration	Two matched Schottky diodes sharing cathode - Enables symmetrical RF detection without discrete node interconnection.
Low RF series resistance	15 Ω at 100 MHz - Reduces insertion loss and improves conversion efficiency in passive mixers and envelope detectors.
High-temperature operation	150 °C max junction temperature - Ensures reliability in thermally constrained RF modules near power amplifiers or filters.

Applications

RF Envelope Detection

DC Offset Compensation

Use Scenario: Demodulating AM or pulsed RF signals in wireless sensor receivers and RFID readers.

IC Role / Device Role / Timing Role: Dual-anode Schottky pair rectifies RF input while shared cathode delivers clean DC envelope output.

Use Value: Sub-1 pF capacitance prevents high-frequency roll-off; matched diodes ensure amplitude symmetry in dual-path detection.

Use Scenario: Stabilizing baseband DC operating point against temperature-induced drift in LNA or mixer bias networks.

IC Role / Device Role / Timing Role: Common-cathode configuration provides matched thermal tracking between two bias paths.

Use Value: Low V_F drift (230–260 mV at 125 °C, 5 mA) enables predictable offset correction across industrial temperature range.

Dual-Band Signal Switching

RF Power Monitoring

Use Scenario: Selecting between two RF bands (e.g., 868 MHz and 915 MHz ISM) using shared cathode as control return path.

IC Role / Device Role / Timing Role: Independent anodes serve as band-select inputs; cathode acts as unified RF ground reference.

Use Value: 15 Ω RF resistance and 1.5 nH series inductance minimize insertion loss and phase skew between bands.

Use Scenario: Sampling forward/reflected RF power in antenna tuning circuits and PA protection loops.

IC Role / Device Role / Timing Role: One diode detects forward power, the other reflected; shared cathode feeds comparator input.

Use Value: Matched C and V_F characteristics ensure consistent detection sensitivity across both paths, improving VSWR accuracy.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
NSVRB540DFT3G	Single-diode SOD-923, 30 V V_RRM, 0.7 pF C, 200 mA I_F	Lacks common-cathode dual configuration; higher current rating but no inherent matching	Use when higher reverse voltage or current headroom is needed, and dual-diode matching is not required.
BAT54CW	Common-cathode SOT-323, 30 V V_RRM, 10 pF C (typ), 200 mA I_F	10× higher capacitance limits use above ~300 MHz; higher I_F suits power-sensitive detector loads	Select for cost-sensitive 2.4 GHz ISM applications where 10 pF capacitance is acceptable and higher current capability is beneficial.

Compared with NSVRB540DFT3G and BAT54CW, the BAS69-05WFILM uniquely balances ultra-low capacitance (<1 pF), matched dual-diode topology, and SOT-323 RF-optimized layout-making it optimal for precision 868/915 MHz envelope detection where signal integrity and thermal tracking outweigh raw current handling.

FAQ

What is the maximum RF frequency range supported by BAS69-05WFILM?

The BAS69-05WFILM is characterized up to 100 MHz for dynamic parameters like RF resistance and capacitance, but its <1 pF junction capacitance and 15 Ω RF resistance enable practical use through 1 GHz in detector and sampling applications. Performance beyond 500 MHz depends on PCB layout parasitics and matching network design.

Can BAS69-05WFILM be used in place of a single Schottky diode?

Yes, only one anode and the shared cathode can be used as a single Schottky diode, with the second anode left unconnected. However, doing so forfeits the thermal and electrical matching benefits of the dual configuration and does not reduce package size or cost versus dedicated single-diode variants like BAS69WFILM.

Is BAS69-05WFILM suitable for automotive applications?

No-BAS69-05WFILM is not qualified to AEC-Q200 or automotive-grade reliability standards. ST specifies it for industrial and consumer RF applications only. For automotive environments, consider ST's AEC-Q200-qualified RF diodes such as the SM712 series, which offer enhanced ESD and temperature robustness.

How does the common-cathode configuration improve thermal stability in RF detectors?

The shared cathode ensures both diodes experience nearly identical thermal gradients and junction temperatures during operation. This matching minimizes V_F mismatch drift over temperature, critical for maintaining amplitude balance in differential detectors and reducing DC offset error in envelope recovery circuits.
