Key Features
- 0.24V maximum forward voltage in DO-35 axial package enabling low-loss rectification in high-efficiency power circuits
- General-purpose silicon Schottky diode optimized for high-speed switching applications up to 200 MHz
- Isolated single-chip configuration in DO-35 package for straightforward PCB mounting and thermal management
Applications
The BAT85S-TR Schottky diode is used in RF detector circuits, low-dropout rectifiers, and high-speed switching applications where the 0.24V forward voltage drop delivers higher efficiency than standard silicon PN-junction diodes. It is commonly employed in AM/FM radio receiver front ends, reverse polarity protection circuits, and low-power DC-DC converter output stages.

Frequently Asked Questions
How does the 0.24V forward voltage of BAT85S-TR compare to a standard silicon rectifier for power efficiency?
A standard silicon PN-junction rectifier has a forward voltage of approximately 0.6V to 0.7V, while the BAT85S-TR's maximum 0.24V forward drop reduces conduction losses by roughly 60%. In a 5V output rectifier stage carrying 500 mA, this saves approximately 180 mW of wasted heat.
What switching speed does the BAT85S-TR support and which RF or detection circuits benefit most?
The BAT85S-TR is specified for high-speed switching suitable for frequencies up to 200 MHz, making it appropriate for AM and FM radio detector stages, envelope detectors, and mixer applications in communications receivers operating below 200 MHz carrier frequencies.
What is the package style of the BAT85S-TR and how does it affect PCB layout in low-current signal applications?
The BAT85S-TR uses an axial DO-35 package with a body diameter of approximately 1.9 mm, which can be mounted horizontally to minimize board height or vertically to reduce footprint. For signal-level circuits below 100 mA, the DO-35 package provides adequate thermal dissipation without a heat sink.
