Product details
Overview
BAT54LPS-7 from Diodes Incorporated is a 30V, 200mA surface-mount Schottky barrier diode in an ultra-small X2-DFN1006-2 package, featuring low forward voltage (428 mV @ 1 mA), fast reverse recovery (5.0 ns), and PN junction guard ring for ESD/transient protection - used in compact DC-DC converter output rectification and USB port polarity protection.
For engineers reviewing the BAT54LPS-7 datasheet, BAT54LPS-7 pinout, BAT54LPS-7 application, or BAT54LPS-7 equivalent, key selection criteria include its 30V VRRM rating, sub-1V VF at 100mA, 10pF junction capacitance at 1V, thermal resistance of 400°C/W, and compatibility with high-density PCB layouts requiring leadless 1.0×0.6mm footprints.
Technical Context
This Schottky diode employs a planar silicon structure with a PN junction guard ring to suppress edge breakdown and improve transient robustness without compromising switching speed. Its low barrier height enables forward conduction starting below 0.3V while maintaining 30V reverse blocking capability.
The X2-DFN1006-2 package uses NiPdAu-plated copper leadframe and mold compound rated UL 94V-0, supporting reflow soldering per J-STD-020 Level 1 moisture sensitivity. Thermal performance is defined on FR-4 with manufacturer-recommended pad layout, yielding 400°C/W junction-to-ambient resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse voltage before breakdown; sets upper limit for DC blocking in 24V system rails. |
| IF(AV) | 200 mA - Continuous forward current rating; defines steady-state power delivery capacity in low-power rectifiers. |
| VF @ 100mA | 650 mV - Forward voltage drop at rated load; directly impacts conduction loss and thermal rise in compact converters. |
| tRR | 5.0 ns - Reverse recovery time; enables efficient operation in >1 MHz switching topologies like synchronous buck controllers. |
| CT @ 1V | 10 pF - Junction capacitance at 1V reverse bias; limits high-frequency signal coupling and affects EMI filtering design. |
| RθJA | 400 °C/W - Junction-to-ambient thermal resistance on standard FR-4; determines temperature rise under 250 mW dissipation. |
| IR @ 25V | 2.0 µA - Max reverse leakage at near-rated voltage; critical for battery-powered circuits where standby current must be minimized. |
Pinout & Package
Package: X2-DFN1006-2 - 1.0 mm × 0.6 mm, 0.37 mm height, leadless dual-terminal surface-mount package with exposed thermal pad (not electrically connected), NiPdAu terminal finish, and cathode marked by bar on bottom side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Terminal 1) | Forward current entry point | Connected to lower-potential node (e.g., ground or switch node) in reverse polarity protection or freewheeling paths. |
| Cathode (Terminal 2) | Forward current exit / reverse blocking terminal | Marked with bar; ties to higher-potential rail (e.g., VBUS or output) - reverse voltage applied here must stay ≤30V. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 428 mV @ 1 mA - Reduces conduction loss in always-on bias networks and improves efficiency in low-voltage (<3.3V) power rails. |
| Fast switching | 5.0 ns tRR - Enables use in high-frequency DC-DC converters (>1 MHz) without significant switching loss penalties. |
| ESD-protected structure | PN junction guard ring - Provides inherent immunity to ±8kV HBM ESD events without external TVS, simplifying USB/IO interface protection. |
| Ultra-compact footprint | 1.0 × 0.6 mm body - Saves >60% board area vs. SOD-123; supports miniaturized wearables and space-constrained IoT modules. |
Applications
| USB Port Polarity Protection | Low-Power DC-DC Output Rectification |
|---|---|
Use Scenario: Preventing damage from reversed USB cable insertion in portable chargers and peripheral hubs. IC Role / Device Role / Timing Role: Unidirectional current gate placed between VBUS and downstream LDO input. Use Value: 30V VRRM safely blocks miswired 5V inputs; 650 mV VF at 100mA limits dropout to <1% of rail, preserving regulation margin. | Use Scenario: Freewheeling path in 3.3V/1A buck converter for MCU power supply in industrial sensors. IC Role / Device Role / Timing Role: Synchronous rectifier replacement in non-synchronous topology. Use Value: 5.0 ns tRR ensures clean turn-off during 2 MHz switching; 10 pF CT avoids resonance with 22 µH inductor at operating frequency. |
| Signal-Level Clamping | Reverse Battery Protection |
Use Scenario: Limiting analog sensor input voltage excursions to ±0.3V beyond supply rails in automotive cabin controllers. IC Role / Device Role / Timing Role: Clamp diode tied between signal line and AVDD/AGND. Use Value: Low VF (428 mV @ 1 mA) establishes precise clamping threshold; guard ring prevents latch-up during ESD transients on CAN/LIN bus lines. | Use Scenario: Blocking reverse current when Li-ion battery pack is inserted backward into handheld medical device. IC Role / Device Role / Timing Role: Series anode-cathode path in main power rail upstream of PMIC. Use Value: 200 mA IF(AV) sustains continuous load during normal operation; 2.0 µA IR at 25V minimizes quiescent drain in sleep mode. |
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 X2-DFN1006-2 package; VF = 500 mV @ 10 mA (vs. 580 mV for BAT54LPS-7); slightly lower IR (1.0 µA @ 25V). | Optimized for lower-current signal clamping where 10 mA test condition better reflects actual use. | Select when tighter VF consistency at mid-range currents is prioritized over absolute minimum VF at 1 mA. |
| NSR0230HT1G | Different package (SOD-523, 1.2×0.8 mm); higher VF (550 mV @ 100 mA); same 30V VRRM and 5 ns tRR. | Larger footprint but more robust handling; preferred in manual assembly or prototyping environments. | Choose when board assembly process lacks fine-pitch DFN capability or when thermal mass requirements exceed X2-DFN1006-2 limits. |
Compared with SBAT54LT1G and NSR0230HT1G, BAT54LPS-7 delivers the lowest VF at 1 mA (428 mV) and smallest footprint (1.0×0.6 mm), making it optimal for ultra-low-power always-on circuits and space-constrained multilayer PCBs where thermal management relies on copper spreading rather than package mass.

FAQ
What is the maximum junction temperature for BAT54LPS-7 during continuous operation?
The BAT54LPS-7 has an operating junction temperature range of –65°C to +125°C. Under continuous 200 mA forward current with 250 mW power dissipation on a standard FR-4 board, junction temperature rise is limited to 100°C above ambient (400°C/W × 0.25 W), staying within safe limits up to +25°C ambient.
Does BAT54LPS-7 require a thermal pad connection on the PCB?
No - the X2-DFN1006-2 package features an exposed thermal pad that is not electrically connected and does not require soldering to a copper pour. Thermal transfer occurs through the two terminals and package molding compound; Diodes' recommended pad layout provides sufficient heat dissipation without additional thermal vias.
Can BAT54LPS-7 be used in automotive applications?
The BAT54LPS-7 itself is not AEC-Q200 qualified. For automotive use, Diodes offers the Q-suffix variant BAT54LPSQ-7, which undergoes PPAP, is manufactured in IATF 16949 facilities, and meets AEC-Q200 stress testing requirements for passive components.
How does the PN junction guard ring affect ESD performance?
The integrated PN junction guard ring suppresses edge breakdown during fast transients, enabling the BAT54LPS-7 to withstand ≥8 kV HBM ESD without external protection. This eliminates need for discrete TVS diodes in USB data line clamping and low-speed digital IO protection circuits.
