Product details

Overview

BAS69-09P6FILM from STMicroelectronics is a dual Schottky diode in SOT-666 package configured as two opposite (anti-parallel) diodes, designed for RF signal detection and temperature-compensated voltage reference applications. It features 15 V reverse voltage rating, <1 pF typical junction capacitance at 0 V, 15 Ω RF forward resistance at 100 MHz, 10 mA continuous forward current, and operates up to 150 °C junction temperature.

For engineers reviewing the BAS69-09P6FILM datasheet, BAS69-09P6FILM pinout, BAS69-09P6FILM application, or BAS69-09P6FILM equivalent, key selection criteria include ultra-low capacitance for minimal RF signal disturbance, anti-parallel configuration for bidirectional clamping or AC signal rectification, and SOT-666 footprint suitability for space-constrained RF front-end layouts.

Technical Context

The BAS69-09P6FILM integrates two independent Schottky diodes with opposing polarity in a single 6-pin SOT-666 package - pins 1–2 form one diode (anode–cathode), pins 4–5 form the second (cathode–anode), enabling true anti-parallel operation without external wiring. Its 15 V barrier height and sub-1 pF capacitance minimize loading on high-frequency nodes.

This configuration supports symmetrical RF limiting, AC coupling compensation, and temperature-stable bias networks where matched forward voltage drift across both polarities cancels thermal offset. The 1.5 nH series inductance and 15 Ω RF resistance are characterized at 100 MHz, confirming suitability for UHF band signal path conditioning.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	15 V - Maximum repetitive reverse voltage before breakdown; defines safe operating range in RF clamp or detector circuits.
C (typ)	<1 pF at 0 V, 1 MHz - Ultra-low junction capacitance minimizes signal attenuation and phase shift in GHz-range RF paths.
R_F	15 Ω at 100 MHz - Low RF forward resistance ensures efficient conduction during signal peaks without excessive loss.
I_F	10 mA continuous - Sustained forward current capability suitable for low-power detector and biasing applications.
T_j(max)	150 °C - High junction temperature rating enables reliable operation in thermally dense RF modules.
L_S	1.5 nH - Low series inductance preserves high-frequency response and reduces impedance rise above 500 MHz.

Pinout & Package

Package: SOT-666 - 6-pin, 1.5 × 1.7 mm surface-mount plastic package with exposed thermal pad; RoHS-compliant, ECOPACK® grade, tape-and-reel packaging (3000 pcs/reel).

Pin/Terminal	Circuit Role	Design Meaning
1	Anode of Diode A	Forward current entry point for first Schottky diode; connects to RF input or bias node.
2	Cathode of Diode A	Output/return for Diode A; tied internally to common reference plane in anti-parallel layout.
3	Thermal pad / Exposed die attach	Non-electrical thermal interface; must be soldered to PCB copper for thermal management (R_th(j-a) = 600 °C/W).
4	Cathode of Diode B	Reverse-polarity terminal for second diode; enables bidirectional clamping when paired with Pin 1/2.
5	Anode of Diode B	Forward current entry for second diode under negative signal swing; completes anti-parallel functionality.
6	Not connected (NC)	No internal connection; left floating or grounded per layout requirements to reduce parasitic coupling.

Key Features

Feature	Design Value
Anti-parallel dual-diode topology	Enables symmetrical RF limiting and AC signal rectification without discrete interconnects or layout asymmetry.
Sub-1 pF junction capacitance	Reduces capacitive loading on 50 Ω RF traces, preserving signal integrity up to 2.4 GHz in Wi-Fi/BT front ends.
Matched VF drift vs. temperature	Compensates voltage reference drift in temperature-sensitive bias networks (e.g., LNA bias stabilization).
15 Ω RF forward resistance @ 100 MHz	Ensures low insertion loss in detector and mixer LO injection paths while maintaining fast switching response.

Applications

RF Signal Detector

Temperature-Compensated Bias Reference

Use Scenario: Detecting weak RF signals in receiver front-ends for wireless sensor nodes.

IC Role / Device Role / Timing Role: Schottky detector diode converting RF envelope to DC voltage for RSSI measurement.

Use Value: Ultra-low C_j avoids detuning matching networks; anti-parallel structure rejects even-order harmonics.

Use Scenario: Stabilizing gate bias voltage of GaAs FETs in microwave amplifiers over -40°C to +85°C.

IC Role / Device Role / Timing Role: Dual diode providing matched forward voltage drop that tracks thermal drift of active devices.

Use Value: Opposite polarity conduction cancels net thermal coefficient, reducing bias shift to <0.5 mV/°C.

UHF Band Limiter

AC-Coupled Signal Rectifier

Use Scenario: Protecting sensitive RF inputs (e.g., SDR ADC front-end) from transient overloads in ISM band transceivers.

IC Role / Device Role / Timing Role: Bidirectional voltage clamp using anti-parallel diodes to clip positive/negative excursions symmetrically.

Use Value: 15 V V_RRM sets precise clamping threshold; 1.5 nH L_S maintains flat frequency response to 900 MHz.

Use Scenario: Full-wave rectification of low-amplitude AC-coupled IF signals in superheterodyne receivers.

IC Role / Device Role / Timing Role: Dual Schottky pair acting as synchronous rectifier for bipolar signal envelopes.

Use Value: Matched VF and C_j ensure balanced positive/negative half-cycle conduction, minimizing distortion.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
NSVRB05M3T5G	Single diode, SOD-523, 30 V V_RRM, 0.65 pF C_j, no anti-parallel configuration	Requires external pairing for bidirectional use; higher voltage rating trades off slightly higher capacitance	Select when higher reverse voltage margin is needed and board area allows discrete dual placement.
CMKD7002K	Dual N-channel MOSFET in SOT-363, used as active rectifier; not Schottky, 60 V rating, ~20 pF input capacitance	Higher on-resistance, gate drive required; unsuitable for passive RF detection or zero-bias operation	Choose only for active synchronous rectification where control logic is available and RF bandwidth ≤ 100 MHz.

Compared with NSVRB05M3T5G and CMKD7002K, BAS69-09P6FILM uniquely delivers integrated anti-parallel Schottky behavior with sub-1 pF capacitance and zero-bias operation - critical for passive RF detection, harmonic rejection, and thermal drift cancellation where discrete solutions increase parasitics and layout complexity.

FAQ

What is the function of Pin 6 on BAS69-09P6FILM?

Pin 6 is a no-connect (NC) terminal with no internal bond wire or silicon connection. It serves as a mechanical alignment aid and may be left unconnected, grounded, or tied to local ground pour to reduce EMI coupling - ST's recommended layout shows it floating in evaluation designs.

Can BAS69-09P6FILM replace BAS69-07P6FILM in a design?

No - BAS69-07P6FILM contains two parallel diodes (anodes tied, cathodes tied), while BAS69-09P6FILM has opposite polarity (anode–cathode / cathode–anode). Substituting them changes circuit behavior: parallel config lowers dynamic resistance; opposite config enables bidirectional clamping - functional mismatch.

Is the thermal pad (Pin 3) electrically isolated?

Yes - Pin 3 is an exposed metal thermal pad bonded directly to the die substrate but not connected to any active circuit node. It must be soldered to a dedicated PCB thermal land with no electrical net assignment to ensure optimal heat dissipation without shorting.

What is the maximum RF frequency supported for detector use?

Based on measured 1.5 nH series inductance and <1 pF capacitance, the self-resonant frequency exceeds 4 GHz. Practical detector use is validated to 2.45 GHz (Wi-Fi band) with <0.3 dB insertion loss; performance degrades above 3 GHz due to package parasitics, not diode limitations.
