Product details

Overview

BAT64A-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 maximum 0.75 V forward voltage at 100 mA. It features a PN junction guard ring for transient protection and is AEC-Q101 qualified for automotive reliability.

For engineers reviewing the BAT64A-7-F datasheet, BAT64A-7-F pinout, BAT64A-7-F application, or BAT64A-7-F equivalent, this device is selected for low-voltage, high-speed switching in power management, signal clamping, and polarity protection circuits where low VF and fast tRR are critical.

Technical Context

This Schottky diode operates with a low forward voltage drop (≤750 mV @ 100 mA), enabling efficient power conversion in space-constrained DC/DC converters and battery-powered systems. Its 3.0 ns reverse recovery time supports high-frequency switching up to several hundred MHz in RF detector and mixer applications.

The integrated PN junction guard ring provides robust ESD and transient immunity without external components, while the 6.0 pF junction capacitance at 1 V reverse bias ensures minimal signal distortion in high-speed data line protection and antenna switching circuits.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	40 V - Maximum repetitive reverse blocking voltage before breakdown; defines safe operating range in 24 V and 36 V automotive supply rails.
I_O	250 mA - Continuous forward current rating; supports load-switching and reverse-polarity protection in compact IoT sensor nodes.
V_F max	750 mV @ 100 mA - Low conduction loss enables >95% efficiency in low-voltage (<5 V) buck converter freewheeling paths.
t_RR	3.0 ns - Ultrafast recovery minimizes switching loss and ringing in 1–10 MHz DC/DC controllers and RF envelope detectors.
C_T	6.0 pF @ 1 V - Low junction capacitance preserves signal integrity in 50 Ω RF front-end clamping and antenna diversity switching.
I_R max	2.0 µA @ 40 V - Low leakage maintains accuracy in precision voltage reference bias networks and high-impedance sensor interfaces.

Pinout & Package

Package: SOT23 - 3-terminal plastic surface-mount package with matte tin-plated alloy 42 leadframe; moisture sensitivity level 1 per J-STD-020; weight ≈ 0.008 g.

Pin/Terminal	Circuit Role	Design Meaning
1 (Anode)	Forward current entry point	Connected to input/source side in reverse-polarity protection; requires low-inductance trace routing for RF applications.
2 (Cathode)	Forward current exit / reverse voltage reference	Typically tied to ground or system return; serves as clamping reference node in ESD protection schemes.
3 (Anode)	Internal die connection (dual-anode configuration)	Shared anode structure enables dual-diode functionality in single-package footprint; verified via Diodes Inc. marking K66 and internal schematic.

Key Features

Feature	Design Value
Low turn-on voltage	VF ≤ 430 mV @ 10 mA - Reduces power loss in always-on battery backup circuits and low-power microcontroller I/O protection.
Fast switching	tRR = 3.0 ns - Enables use in 10+ MHz clock line clamping and high-speed digital bus termination without timing skew.
PN junction guard ring	Integrated transient suppression - Eliminates need for external TVS in CAN/LIN bus interface protection and automotive body control modules.
AEC-Q101 qualification	Automotive-grade reliability - Validated for operation across −65 °C to +150 °C ambient, supporting under-hood and infotainment applications.

Applications

Reverse Polarity Protection

RF Signal Clamping

Use Scenario: Preventing damage from incorrect battery installation in portable medical monitors and handheld test equipment.

IC Role / Device Role / Timing Role: Low-loss series rectifier placed between battery terminal and main power rail.

Use Value: 0.75 V VF at 100 mA limits voltage drop and heat generation, preserving runtime and avoiding thermal derating in sealed enclosures.

Use Scenario: Protecting LNA inputs in GPS/GNSS receivers from antenna coupling transients and ESD events.

IC Role / Device Role / Timing Role: Passive clamp diode shunting RF signal path to ground during overvoltage conditions.

Use Value: 6.0 pF capacitance and 3.0 ns tRR prevent signal attenuation and phase distortion below 2.5 GHz.

DC/DC Freewheeling Diode

Logic-Level Signal Steering

Use Scenario: Freewheeling path in 3.3 V synchronous buck converters powering FPGA I/O banks and DDR memory subsystems.

IC Role / Device Role / Timing Role: Uncontrolled freewheeling diode replacing MOSFET body diode during dead-time intervals.

Use Value: 250 mA I_O rating and 500 °C/W R_θJA support continuous conduction mode operation without heatsinking at 1 MHz switching.

Use Scenario: Bidirectional level translation between 1.8 V MCU GPIO and 3.3 V peripheral I²C lines in wearables.

IC Role / Device Role / Timing Role: Passive OR-ing diode enabling open-drain logic sharing across voltage domains.

Use Value: Low 0.35 V VF @ 1 mA ensures valid logic-low threshold even with weak pull-ups, minimizing bus contention.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SBAT54AWT1G	Higher VF (0.95 V @ 100 mA); same SOT23-3 package; 30 V V_RRM.	Lower reverse voltage margin; unsuitable for 24 V automotive systems but acceptable in 5 V USB-C PD designs.	Select when cost sensitivity outweighs VF penalty and 30 V blocking suffices.
NSR0230HT1G	Lower I_O (200 mA); lower C_T (4.5 pF); same 40 V V_RRM; SOD-323 package.	Smaller footprint but reduced current handling; better for ultra-compact RF filters than power rail protection.	Prefer for space-constrained 2.4 GHz Wi-Fi front-end clamping where size trumps current rating.

Compared with SBAT54AWT1G and NSR0230HT1G, BAT64A-7-F delivers superior balance of 40 V blocking, 250 mA current, and 0.75 V VF in standard SOT23-making it optimal for automotive body electronics and industrial 24 V sensor interfaces requiring AEC-Q101 compliance.

FAQ

Is BAT64A-7-F pin-compatible with BAT64-7-F?

Yes. BAT64A-7-F shares identical SOT23-3 pinout and mechanical dimensions with BAT64-7-F. The "A" suffix denotes tighter VF distribution (K66 marking) and same AEC-Q101 qualification, making it a direct replacement in all layouts designed for BAT64-7-F.

What is the maximum junction temperature during continuous 250 mA operation?

At 250 mA and 25 °C ambient, power dissipation is ~187.5 mW (0.75 V × 0.25 A). With R_θJA = 500 °C/W, junction rise is 93.8 °C, yielding T_J ≈ 119 °C - within the −65 °C to +150 °C rating. Derating per Figure 4 applies above 75 °C ambient.

Does BAT64A-7-F support reflow soldering per J-STD-020?

Yes. Rated for moisture sensitivity level 1 and qualified for standard Pb-free reflow profiles (peak 260 °C, 30 sec). Matte tin plating ensures reliable wetting, and the "Green" molding compound meets UL 94V-0 flammability requirements.

Can BAT64A-7-F be used in AC signal detection applications?

Yes. Its 3.0 ns tRR and 6.0 pF C_T enable accurate RF envelope detection up to 2.5 GHz. Forward conduction begins below 0.35 V, allowing sensitive demodulation of small-signal AM waveforms in GPS and ISM-band receivers.
