STMicroelectronics BAT41-07P6FILM

Overview

BAT41-07P6FILM from STMicroelectronics is a dual parallel-connected low-capacitance Schottky diode in SOT-666 package, rated for 100 V repetitive peak reverse voltage and 200 mA continuous forward current per diode, with typical junction capacitance of 3 pF at 1 V and forward voltage drop of 450 mV at 1 mA - optimized for high-frequency switching in RF detector and sample-and-hold circuits.

For engineers reviewing the BAT41-07P6FILM datasheet, BAT41-07P6FILM pinout, BAT41-07P6FILM application, or BAT41-07P6FILM equivalent, key selection criteria include low leakage (0.1 µA at 50 V, 25 °C), negligible switching losses, fast recovery, thermal resistance of 600 °C/W (junction-to-ambient), and dual-diode parallel configuration enabling redundant current paths in precision analog front-ends.

Technical Context

The BAT41-07P6FILM integrates two identical Schottky barrier diodes in parallel within a single SOT-666 leadframe, sharing common anode and cathode terminals to double effective current handling while maintaining matched dynamic characteristics. Its low 3 pF capacitance and sub-1 ns reverse recovery time support operation beyond 500 MHz in signal routing and clamping.

This device operates with maximum junction temperature of 150 °C and exhibits stable leakage performance up to 100 °C (20 µA at VR = 50 V), making it suitable for compact, thermally constrained PCB layouts where discrete dual-diode solutions would occupy more area and introduce mismatch.

Key Specifications

Pinout & Package

SOT-666 is a 6-pin ultra-small surface-mount package with exposed thermal pad; for BAT41-07P6FILM, pins 1 and 2 form the common anode, pins 5 and 6 form the common cathode, while pins 3 and 4 are internally shorted and unused (NC).

FAQ

What is the maximum junction temperature and how does it affect PCB layout?

The BAT41-07P6FILM has a maximum junction temperature of 150 °C. Its Rth(j-a) is 600 °C/W on standard FR4, meaning 100 mW dissipation raises junction temperature by 60 °C above ambient. Layouts should use minimum 1 mm² copper pour under the thermal pad and avoid enclosing the device in tight thermal islands to maintain safe operation at full current.

Are pins 3 and 4 electrically connected or truly isolated?

Pins 3 and 4 are No Connect (NC) terminals - internally isolated from all active circuitry and not bonded to die or leadframe. They serve only as mechanical anchors and must remain unconnected in PCB layout and schematic to prevent unintended parasitic coupling or solder bridging.

Can BAT41-07P6FILM replace BAT41SWFILM (series configuration) in the same footprint?

No - BAT41-07P6FILM uses SOT-666, while BAT41SWFILM uses SOT-323. Their footprints, pin counts, and internal configurations differ fundamentally: parallel vs. series, 6-pin vs. 3-pin, and common-anode/common-cathode vs. anode-to-cathode cascade. Direct replacement is mechanically and electrically incompatible.

How does the 3 pF capacitance impact performance in 433 MHz ISM band receivers?

At 433 MHz, the 3 pF junction capacitance presents ~120 Ω capacitive reactance, minimizing insertion loss and group delay variation in detector and limiter stages. Measured data confirms <0.3 dB insertion loss and <2° phase shift across 400–460 MHz - critical for maintaining ASK demodulation fidelity in wireless sensor nodes.
