Product details
Overview
BAT54J/ZLX from Diodes Incorporated is a dual common-cathode Schottky barrier diode in SOT-23 package, with 30 V reverse voltage rating, 200 mA average forward current, and 0.24 V typical forward voltage at 10 mA - used in polarity protection and signal clamping circuits for USB interface power rails.
For engineers reviewing the BAT54J/ZLX datasheet, BAT54J/ZLX pinout, BAT54J/ZLX application, or BAT54J/ZLX equivalent, key selection factors include low forward voltage drop, fast switching speed (trr < 5 ns), dual-diode configuration in compact SOT-23, and guaranteed 150°C junction temperature operation.
Technical Context
This dual Schottky diode integrates two anode terminals sharing one cathode terminal, enabling independent clamping or OR-ing functions in space-constrained DC bias and signal routing paths. Its epitaxial planar construction ensures stable leakage performance (< 1 µA at 25°C) and repeatable forward conduction characteristics across temperature.
The device operates without minority-carrier storage delay, supporting high-frequency signal rectification up to 100 MHz and enabling clean transient suppression in 3.3 V/5 V logic-level interfaces where fast recovery and minimal voltage loss are critical.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54LT1G | Same SOT-23 package, but 0.33 V VF @ 10 mA and 2 µA IR @ 25°C | Higher forward loss limits use in sub-100 mW portable designs | Select when cost sensitivity outweighs 90 mV VF penalty and leakage tolerance >2 µA |
| BAT54C,115 | Identical electrical specs but molded in SOT-323 (1.7 × 1.25 mm), 0.9 mm height | Smaller footprint unsuitable for reflow-compatible 0402 passive land patterns | Choose only if board space is constrained below 2.9 × 1.3 mm and thermal mass permits SOT-323 reflow profile |
Compared with SBAT54LT1G and BAT54C,115, BAT54J/ZLX delivers the lowest forward voltage in standard SOT-23, making it optimal for thermally limited or battery-sensitive applications where every millivolt of drop impacts runtime or thermal margin.

FAQ
What is the maximum peak forward surge current (IFSM) for BAT54J/ZLX?
The BAT54J/ZLX has a rated non-repetitive peak forward surge current of 600 mA per diode, tested with a single half-sine wave pulse of 10 ms duration at 25°C ambient. This rating supports brief inrush events during hot-plug insertion of USB peripherals without degradation.
Is BAT54J/ZLX RoHS compliant and halogen-free?
Yes, BAT54J/ZLX meets RoHS Directive 2011/65/EU and is certified halogen-free per IEC 61249-2-21, with bromine and chlorine content below 900 ppm each. The device carries Diodes Incorporated's standard green marking and complies with JEDEC J-STD-020 moisture sensitivity level 1.
Can BAT54J/ZLX be used in reverse-biased avalanche mode?
No - BAT54J/ZLX is not rated or characterized for controlled avalanche operation. Its 30 V VR rating is strictly for blocking; exceeding this voltage risks irreversible breakdown due to lack of specified avalanche energy handling capability.
How does the common-cathode configuration affect thermal coupling between the two diodes?
Thermal resistance from junction-to-case (RθJC) is 250°C/W per diode, and both junctions share the same die substrate. Under simultaneous conduction, self-heating raises total junction temperature additively - derating to ≤120 mA combined forward current is recommended for sustained operation above 85°C ambient.
