Product details

Overview

BAS69KFILM from STMicroelectronics is a single low-capacitance Schottky diode in SOD-523 package, designed for RF signal detection and temperature-compensated voltage reference 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 BAS69KFILM datasheet, BAS69KFILM pinout, BAS69KFILM application, or BAS69KFILM equivalent, key selection criteria include ultra-low C_j, minimal parasitic inductance (1.5 nH), low forward voltage (380 mV @ 1 mA), and suitability for space-constrained RF front-end and bias compensation designs.

Technical Context

The BAS69KFILM employs a 15 V barrier Schottky junction optimized for minimal capacitive loading on high-frequency signals. Its <1 pF capacitance at 0 V reverse bias and 15 Ω RF forward resistance at 100 MHz enable clean RF envelope detection without signal distortion.

Thermal design is supported by a 600 °C/W junction-to-ambient thermal resistance (SOD-523 package) and operation across –65 °C to +150 °C storage and operating ranges. The device uses lead-free, RoHS-compliant ECOPACK® packaging with UL94 V0 epoxy.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	15 V - Maximum repetitive reverse voltage before breakdown; sets usable RF signal swing limit in detector applications.
C_j (typ)	<1 pF @ 0 V, 1 MHz - Minimizes RF signal shunting and preserves high-frequency integrity in mixer/detector nodes.
V_F	380 mV @ 1 mA, 25 °C - Enables low-threshold detection of weak RF signals without external amplification.
I_F	10 mA continuous - Defines maximum DC bias current for stable temperature-compensated reference use.
L_S	1.5 nH - Low series inductance maintains impedance match and bandwidth in 50 Ω RF paths.
R_F	15 Ω @ 100 MHz - Predictable small-signal dynamic resistance critical for linear envelope detection accuracy.

Pinout & Package

Package: SOD-523 - ultra-compact surface-mount package (0.6 × 1.2 mm footprint), 0.2 mm pitch, 0.25 mm nominal lead width, suitable for high-density RF PCB layouts.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry / RF signal input node	Connected to RF source or bias line; low V_F enables efficient rectification at microamp-level currents.
Cathode	Forward current exit / RF ground reference	Typically tied to AC ground or bias return; low C_j minimizes coupling into adjacent traces.

Key Features

Feature	Design Value
Ultra-low junction capacitance	<1 pF typ. - Preserves signal integrity in 1–3 GHz RF detector and sampling circuits.

Minimal parasitic inductance	1.5 nH - Reduces resonance effects and maintains broadband performance up to 1 GHz.
High-temperature operation	150 °C max T_j - Supports reliable function in thermally dense RF modules and power amplifier bias networks.
Space-saving SOD-523 package	0.6 × 1.2 mm footprint - Allows placement directly at antenna feed points or IC RF pins with minimal trace stubs.

Applications

RF Signal Detector

Use Scenario: Detecting amplitude-modulated RF carrier signals in low-power wireless receivers (e.g., ISM band sensor nodes).

IC Role / Device Role / Timing Role: Schottky diode acting as envelope detector in passive demodulator stage.

Use Value: Sub-1 pF C_j prevents high-frequency roll-off; 380 mV V_F ensures sensitivity to weak signals without active gain.

Use Scenario: Compensating voltage drift in precision oscillator bias networks over –40 °C to +85 °C ambient range.

IC Role / Device Role / Timing Role: Forward-biased diode providing negative temperature coefficient voltage reference.

Use Value: Stable V_F vs. T curve (260 mV @ 125 °C, 380 mV @ 25 °C) enables predictable drift cancellation in TCXO control loops.

Low-Parasitic RF Switch Node

High-Frequency Sampling Gate

Use Scenario: Isolating RF test points during production calibration of 2.4 GHz BLE transceivers.

IC Role / Device Role / Timing Role: Passive RF switch element controlled by DC bias state.

Use Value: 15 Ω R_F and 1.5 nH L_S ensure minimal insertion loss and phase shift below 1 GHz.

Use Scenario: Sampling clock edges in high-speed ADC driver feedback paths for jitter reduction.

IC Role / Device Role / Timing Role: Fast-switching clamp diode limiting overshoot on sampling strobe lines.

Use Value: 60 ns reverse recovery time (inferred from low C_j/R_F) supports clean edge capture at >100 MSPS rates.

Equivalent & Alternatives

The following parts are listed as comparable options for similar low-capacitance Schottky diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
NSVRB70MUT5G	0.7 pF C_j @ 0 V, 30 V V_RRM, SOD-923 package (0.6 × 0.3 mm)	Higher reverse voltage margin; smaller footprint but lower current rating (5 mA I_F)	Preferred where higher V_RRM and minimal area are critical, but not for >5 mA bias applications.
CMKD7001TR	0.9 pF C_j, 20 V V_RRM, dual common-cathode in SOT-363	Dual configuration enables differential detection; higher thermal resistance (700 °C/W)	Used when matched pair behavior or dual-path RF sensing is required, accepting larger board area.

Compared with NSVRB70MUT5G and CMKD7001TR, BAS69KFILM offers optimal balance of 15 V rating, 10 mA current capability, and proven 1.5 nH parasitic inductance-making it preferred for single-diode, space-constrained RF detector and bias compensation roles where thermal robustness and moderate voltage headroom are jointly required.

FAQ

What is the maximum reverse voltage the BAS69KFILM can withstand continuously?

The BAS69KFILM has a repetitive peak reverse voltage (V_RRM) rating of 15 V. This is the maximum DC or sinusoidal reverse voltage that may be continuously applied without risk of junction breakdown. Operation above this value-even briefly-may cause irreversible damage, especially under elevated temperature conditions.

Does BAS69KFILM require a heatsink in typical RF detector applications?

No heatsink is required. With a 600 °C/W junction-to-ambient thermal resistance and only 380 mW maximum power dissipation (10 mA × 380 mV), junction temperature rise remains under 23 °C above ambient at room temperature-well within the 150 °C absolute maximum rating. Standard FR4 PCB copper pads provide sufficient thermal conduction.

Can BAS69KFILM be used in 5G sub-6 GHz front-end designs?

Yes-its <1 pF capacitance, 15 Ω RF resistance at 100 MHz, and verified performance up to 3 GHz in ST application notes confirm suitability for sub-6 GHz envelope detection, bias clamping, and sampling gate functions. Layout must minimize trace inductance and maintain 50 Ω impedance continuity to preserve measured RF parameters.

How does the SOD-523 package affect solder reflow profile requirements?

The SOD-523 package requires standard lead-free reflow per J-STD-020: peak temperature ≤260 °C for ≤10 seconds, with ramp-up rate ≤3 °C/s. Due to its small mass (1.4 mg), thermal soak time must be minimized to avoid tombstoning; recommended stencil aperture is 0.35 × 0.65 mm with 0.1 mm thickness for optimal paste release and alignment.
