Product Overview
onsemi BAT54LT1G is a small-signal Schottky barrier diode in an SMD package, engineered for high-speed switching, circuit clamping, and reverse voltage transient protection. The single-diode configuration provides a 30V reverse breakdown rating with 200mA continuous forward current capability.
Key Features
- Continuous forward current: 200 mA
- Peak repetitive reverse voltage: 30 V
- Forward voltage drop: 0.35 V typical at 10 mA
- Reverse recovery time: 5.0 ns maximum
- Package: SOT-23-3 (TO-236AB) surface mount
- Internal configuration: Single diode (Pin 1 anode, Pin 2 no connection, Pin 3 cathode)
Applications
- Replacing damaged surface-mount clamp diodes on control boards and logic sensor interfaces
- Protecting sensitive microcontroller GPIO pins against inductive spikes and reverse-voltage transients
- Building low-voltage steering logic and efficient polarity protection in compact battery-powered projects
Frequently Asked Questions
What pinout configuration does this SOT-23 package use?
This device uses Style 8 pinout: Pin 1 is the anode, Pin 2 has no internal connection, and Pin 3 is the cathode.
What marking is printed on the package?
The top surface is marked JV3.
How does the BAT54LT1G differ from dual-diode variants like the BAT54A or BAT54C?
The BAT54LT1G houses a single diode connected across pins 1 and 3, whereas BAT54A and BAT54C variants contain dual diodes in common-anode or common-cathode arrangements.
A five-nanosecond switch that steps in before an inductive spike ever knows it had a chance. Solder it into the trace and let the diode take the hit.
