Product details
Overview
BAT54LP-7 from Diodes Incorporated is a surface-mount Schottky barrier diode in an ultra-small X1-DFN1006-2 package, rated for 30 V peak reverse voltage, 200 mA continuous forward current, and featuring a low 240–500 mV forward voltage at 0.1–100 mA. It delivers fast 5.0 ns reverse recovery time and 10 pF junction capacitance at 1 V, making it suitable for high-frequency signal clamping and polarity protection in space-constrained portable electronics.
For engineers reviewing the BAT54LP-7 datasheet, BAT54LP-7 pinout, BAT54LP-7 application, or BAT54LP-7 equivalent, key selection criteria include its cathode-bar-marked DFN1006 footprint, JEDEC-qualified reliability for industrial environments, low thermal resistance (400 °C/W), and ESD-protected PN guard ring-critical for USB data line protection and battery management input stages.
Technical Context
The BAT54LP-7 employs a planar Schottky junction with integrated PN guard ring to suppress transient-induced leakage and improve ESD robustness. Its low forward voltage enables efficient voltage-level translation in 1.8 V/3.3 V I/O interfaces without significant IR drop.
Designed for operation from –65 °C to +150 °C, it maintains stable reverse leakage (<2.0 µA at 25 V) and predictable capacitance (10 pF @ 1 V, 1 MHz) across temperature, supporting reliable performance in automotive-adjacent industrial control modules and wearables.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse blocking voltage before breakdown; sets safe operating limit for 24 V rail clamping |
| IF | 200 mA - Continuous DC forward current rating; defines steady-state power path capability in bias networks |
| VF @ 10 mA | 320 mV - Forward voltage drop at typical signal-level current; minimizes insertion loss in RF detector paths |
| tRR | 5.0 ns - Reverse recovery time; enables use in >100 MHz switching applications like antenna switch control |
| CT @ 1 V | 10 pF - Junction capacitance at 1 V reverse bias; ensures minimal signal coupling distortion in high-speed data lines |
| RθJA | 400 °C/W - Thermal resistance to ambient on FR-4 board; requires minimal copper area for thermal management |
| IR @ 25 V | 2.0 µA - Reverse leakage at near-maximum working voltage; supports low-power sleep-mode integrity |

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 X1-DFN1006-2 package; VF = 370 mV @ 10 mA (higher), tRR = 4 ns (faster) | Slightly higher forward loss but faster switching; better for >200 MHz RF sampling gates | Select when nanosecond-level recovery dominates over voltage drop in high-frequency sampling paths |
| BAT54C-7-F | SC-70 package (2.2 × 1.35 mm); VF = 320 mV @ 10 mA; same VRRM/tRR | Larger footprint; not suitable for ultra-dense layouts where DFN1006 is required | Choose only if legacy SC-70 reflow profile or test probe access is mandatory |
Compared with SBAT54LT1G and BAT54C-7-F, the BAT54LP-7 uniquely balances ultra-compact size, low VF at micro-current levels, and JEDEC-qualified reliability-making it optimal for next-gen wearables and miniaturized industrial sensors where board area and low-power leakage are co-critical.

FAQ
What is the cathode identification method for BAT54LP-7?
The cathode is identified by a visible bar marking on the top surface of the X1-DFN1006-2 package. This bar aligns with Pin 2 in the standard DFN orientation, and the underlying copper pad on the bottom side corresponds to the anode (Pin 1). No silkscreen or dot is used-only the bar serves as polarity indicator.
Can BAT54LP-7 be used in automotive applications?
The BAT54LP-7 is qualified to JEDEC standards referenced in AEC-Q200 for high reliability, but it is not officially AEC-Q200 certified. For automotive-grade use, Diodes offers the BAT54LPQ variant, which undergoes full AEC-Q200 stress testing and carries automotive-specific qualification documentation.
What is the maximum allowable soldering temperature for BAT54LP-7?
The BAT54LP-7 is rated for moisture sensitivity level 1 per J-STD-020, permitting unlimited floor life and peak reflow temperatures up to 260 °C for 30 seconds. The NiPdAu terminal finish ensures robust wetting and intermetallic formation under standard lead-free reflow profiles.
How does the PN guard ring affect ESD performance?
The integrated PN junction guard ring surrounds the Schottky anode, providing a controlled low-impedance path for ESD current to shunt away from the sensitive metal-semiconductor interface. This structure improves human-body-model (HBM) ESD rating to >8 kV, verified per ANSI/ESDA/JEDEC JS-001.
