Product details
Overview
BAT64AW-7-F from Diodes Incorporated is a surface-mount Schottky barrier diode in SOT323 package, rated for 40 V peak reverse voltage, 250 mA average rectified current, and 0.75 V max forward voltage at 100 mA. It features ultra-low capacitance (6.0 pF at 1 V), 3.0 ns reverse recovery time, and PN junction guard ring for transient protection-used in high-frequency signal demodulation and low-loss DC power path switching.
For engineers reviewing the BAT64AW-7-F datasheet, BAT64AW-7-F pinout, BAT64AW-7-F application, or BAT64AW-7-F equivalent, key selection criteria include its 40 V VRRM, sub-0.5 V forward drop at low currents (350 mV @ 1 mA), AEC-Q101 qualification, SOT323 footprint compatibility, and transient-protected junction design for automotive sensor interfaces and RF detector circuits.
Technical Context
This Schottky diode employs a platinum-silicide or similar low-barrier metal-semiconductor junction to achieve fast switching (tRR = 3.0 ns) and minimal forward conduction loss. Its guard-ringed PN structure suppresses edge breakdown under transient stress while maintaining low leakage (IR ≤ 2.0 µA at 40 V).
The device operates across –65°C to +150°C with thermal resistance RθJA = 625°C/W on FR-4 PCB, and derates linearly above 25°C ambient-enabling use in compact, thermally constrained modules such as automotive body control units and portable wireless receivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 40 V - Maximum repetitive reverse blocking voltage before avalanche; sets upper limit for signal swing or bias rail isolation. |
| IO | 250 mA - Continuous DC output current capability; supports low-power supply rail clamping and detector load driving. |
| VF @ 100 mA | 750 mV max - Low forward drop minimizes conduction loss in battery-fed signal paths and RF envelope detectors. |
| IR @ 40 V | 2.0 µA max - Ultra-low leakage preserves signal integrity in high-impedance sensing nodes and precision reference circuits. |
| tRR | 3.0 ns - Fast recovery enables operation up to ~100 MHz in mixer/demodulator applications without tail current distortion. |
| CT @ 1 V | 6.0 pF - Minimal junction capacitance maintains bandwidth in RF coupling, sampling, and antenna switch bias networks. |
| TJ Range | –65°C to +150°C - Extended temperature rating supports under-hood automotive and industrial motor-control feedback paths. |

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 SOT323 package; 30 V VRRM, 200 mA IO, 0.33 V VF @ 10 mA - lower voltage rating, slightly lower current. | Not suitable for 40 V-rated systems; preferred where space-constrained 30 V clamping is sufficient. | Select when system reverse voltage stays below 30 V and lowest possible VF at microamp bias is critical. |
| BAT54AW-7-F | Identical SOT323 footprint and marking; 30 V VRRM, same 250 mA IO, 0.33 V VF @ 10 mA - lower VRRM but identical thermal and packaging specs. | Limited to ≤30 V applications; otherwise drop-in compatible in layout and assembly. | Choose for cost-sensitive designs where 30 V margin suffices and tighter VF tolerance is needed. |
Compared with SBAT54AWT1G and BAT54AW-7-F, BAT64AW-7-F uniquely delivers 40 V blocking with AEC-Q101 qualification-making it the only option among the three for automotive 12 V/24 V systems requiring full load-dump immunity and extended temperature operation.

FAQ
What is the maximum reverse voltage rating for BAT64AW-7-F?
The BAT64AW-7-F has a peak repetitive reverse voltage (VRRM) rating of 40 V. This is the absolute maximum DC or peak AC reverse voltage the diode can block without entering avalanche breakdown under normal operating conditions at 25°C ambient.
Is BAT64AW-7-F suitable for automotive applications?
Yes-BAT64AW-7-F is qualified to AEC-Q101 standards and rated for operation from –65°C to +150°C. Its guard-ringed junction and low leakage make it appropriate for LIN bus protection, sensor signal conditioning, and power rail clamping in automotive ECUs.
How does the SOT323 package affect thermal performance?
In the SOT323 package, BAT64AW-7-F exhibits a junction-to-ambient thermal resistance (RθJA) of 625°C/W on standard FR-4 PCB with recommended pad layout. Derating begins at 25°C ambient, reducing power dissipation linearly to zero at 150°C.
What is the typical forward voltage at low current levels?
At 1 mA forward current and 25°C, the typical forward voltage is 350 mV, with a maximum of 430 mV. This ultra-low turn-on threshold enables reliable signal detection in low-amplitude RF and sensor applications where silicon diodes would remain non-conductive.
