Product details
Overview
BAT64AQ-7-F from Diodes Incorporated is a surface-mount Schottky barrier diode in SOT23 package, rated for 40 V peak reverse voltage, 250 mA average forward current, and 0.75 V max forward voltage at 100 mA. It features a PN junction guard ring for transient protection and is AEC-Q101 qualified for automotive use.
For engineers reviewing the BAT64AQ-7-F datasheet, BAT64AQ-7-F pinout, BAT64AQ-7-F application, or BAT64AQ-7-F equivalent, key selection criteria include low VF at low-to-moderate forward currents (350 mV @ 1 mA), fast 3.0 ns reverse recovery time, 6.0 pF junction capacitance at 1 V, and operation across –55°C to +150°C ambient temperature range.
Technical Context
This Schottky diode uses a metal–semiconductor junction to achieve low forward voltage drop and fast switching-critical for high-frequency rectification and signal clamping. Its guard ring structure enhances ESD and transient robustness without compromising speed or leakage.
Designed for automotive-grade reliability, it meets AEC-Q101 stress testing requirements and is manufactured in IATF16949-certified facilities. The SOT23 package supports automated assembly and delivers thermal resistance of 500°C/W (junction-to-ambient) on FR-4 PCB with recommended pad layout.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54AWT1G | Same SOT23 package; 30 V VRRM, 200 mA IO, 0.33 V VF @ 10 mA - lower voltage rating, lower VF at light loads | Not AEC-Q101 qualified; suited for consumer portables, not automotive | Select when ultra-low VF at microamp bias is critical and automotive qualification is unnecessary |
| NSR0230P2T5G | SOD-523 package; 30 V VRRM, 200 mA IO, 0.35 V VF @ 10 mA - smaller footprint, lower thermal mass | Limited surge rating (1.2 A IFSM) and no guard ring - less robust in transient-prone systems | Choose for space-constrained wearables where board area is prioritized over automotive ruggedness |
Compared with SBAT54AWT1G and NSR0230P2T5G, BAT64AQ-7-F uniquely combines AEC-Q101 qualification, 40 V blocking, guard ring protection, and SOT23 manufacturability-making it the only option among the three validated for under-hood automotive clamping and detection.

FAQ
What is the maximum reverse voltage rating for BAT64AQ-7-F?
The BAT64AQ-7-F has a peak repetitive reverse voltage (VRRM) rating of 40 V. This value is tested per JEDEC standards and represents the maximum DC or repetitive peak reverse voltage the device can block without entering avalanche breakdown under specified thermal conditions.
Is BAT64AQ-7-F suitable for high-frequency RF detector applications?
Yes. With a typical junction capacitance of 6.0 pF at 1 V reverse bias and 3.0 ns reverse recovery time, BAT64AQ-7-F supports RF envelope detection up to 100 MHz. Its low 350 mV forward voltage at 1 mA enables sensitive demodulation of weak RF signals in battery-powered sensors.
Does BAT64AQ-7-F require special PCB layout considerations?
Yes. For optimal thermal performance, Diodes recommends using the SOT23 pad layout published in their package outline documentation (document #PO-SOT23). This includes specific copper area and thermal relief patterns to maintain RθJA ≤ 500°C/W on FR-4 boards and prevent solder joint fatigue during thermal cycling.
How does the PN junction guard ring improve reliability?
The integrated PN junction guard ring surrounds the active Schottky region to suppress edge breakdown during voltage transients. It increases ESD robustness (HBM > 8 kV) and improves immunity to load-dump pulses (ISO 7637-2 Pulse 5a), making BAT64AQ-7-F suitable for automotive power inputs where unclamped surges exceed 40 V.
