Product details

Overview

BAT64S-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 PN junction guard ring for transient protection and is AEC-Q101 qualified for automotive reliability.

For engineers reviewing the BAT64S-7-F datasheet, BAT64S-7-F pinout, BAT64S-7-F application, or BAT64S-7-F equivalent, this part serves as a low-V_F, fast-switching rectifier in power management and signal clamping circuits where low conduction loss and sub-3 ns reverse recovery are critical design requirements.

Technical Context

This Schottky diode uses a planar epitaxial structure with integrated PN guard ring to suppress edge breakdown and improve surge robustness under transient conditions. Its low 0.75 V V_F at 100 mA and 3.0 ns t_RR enable high-efficiency DC-DC output rectification and RF detector applications.

Thermal resistance of 500 °C/W (J-A) and 250 mW power dissipation rating reflect its suitability for compact PCB layouts with limited copper area. The device operates across –65 °C to +150 °C, supporting under-hood automotive environments.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	40 V - Maximum blocking voltage before avalanche; defines safe operating range in 24 V automotive supply rails.
I_O	250 mA - Continuous DC forward current capability; supports low-power buck converter outputs and bias supplies.
V_F @ 100 mA	0.75 V max - Low conduction loss reduces power dissipation and thermal stress in space-constrained designs.
t_RR	3.0 ns typ - Enables high-frequency switching (>10 MHz) in RF detectors and snubberless flyback clamp circuits.
C_T @ 1 V	6.0 pF typ - Minimal junction capacitance preserves signal integrity in high-speed sampling and mixer applications.
I_R @ 40 V	2.0 µA max - Low leakage maintains accuracy in precision voltage reference and sensor bias networks.

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 lower-potential node (e.g., ground or return path) in rectifier configuration.
2 (Cathode)	Forward current exit point	Connected to higher-potential node (e.g., switch node or input rail); marked with cathode band on top view.
3 (Anode)	Second anode terminal (dual-anode configuration)	Enables common-cathode dual-diode topology; used for dual-path clamping or differential signal conditioning.

Key Features

Feature	Design Value

AEC-Q101 qualification	Validated for automotive-grade temperature cycling, HTRB, and UHAST - suitable for engine control and body electronics.

Applications

Automotive LED Lighting Power Supply

USB Port ESD Protection Clamp

Use Scenario: Clamping transients on 12 V LED driver output lines during load dump events.

IC Role / Device Role / Timing Role: Dual-anode Schottky clamp diode providing bidirectional low-V_F path to ground and battery rail.

Use Value: 0.75 V V_F limits clamping voltage to <14.5 V, protecting downstream LED drivers without adding series resistance.

Use Scenario: I/O line protection for USB 2.0 data pairs against ±8 kV contact ESD per IEC 61000-4-2.

IC Role / Device Role / Timing Role: Low-capacitance (6 pF) shunt diode connected between D+ and D− to V_bus/GND.

Use Value: Sub-3 ns t_RR ensures minimal signal distortion during high-speed data transmission up to 480 Mbps.

DC-DC Converter Output Rectifier

RF Signal Detector in AM Receiver

Use Scenario: Synchronous rectification replacement in 3.3 V/500 mA buck converter for industrial IoT sensor node.

IC Role / Device Role / Timing Role: Low-loss freewheeling path during high-side FET off-time; replaces MOSFET gate drive complexity.

Use Value: 250 mW power rating and 500 °C/W R_θJA allow direct mounting on 1 oz Cu without heatsink in 25 mm² footprint.

Use Scenario: Envelope detection of 1–30 MHz AM broadcast signals in portable receiver front-end.

IC Role / Device Role / Timing Role: Zero-bias RF detector leveraging low junction capacitance and sub-nanosecond carrier lifetime.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SBAT54DW-7-F	Dual common-cathode configuration; 30 V V_RRM; 0.45 V V_F @ 10 mA; 20 pF C_T.	Lower V_F at light loads but higher capacitance limits RF use above 5 MHz.	Prefer for low-current bias networks where speed is secondary to conduction efficiency.
NSR0230HT1G	Single diode; 30 V V_RRM; 0.39 V V_F @ 100 mA; 15 pF C_T; SOD-123 package.	Larger footprint and no guard ring; not AEC-Q101 qualified.	Select when automotive qualification is unnecessary and board space allows SOD-123 layout.

Compared with SBAT54DW-7-F and NSR0230HT1G, BAT64S-7-F uniquely combines AEC-Q101 qualification, 40 V rating, 3 ns switching, and dual-anode SOT23 packaging - making it optimal for automotive power clamping and high-frequency signal conditioning where reliability and speed intersect.

FAQ

What is the polarity marking for BAT64S-7-F?

The BAT64S-7-F uses standard SOT23 top-side marking: a single cathode band adjacent to Pin 2 (cathode), with Pins 1 and 3 both serving as anodes. The device is a dual-anode, single-cathode configuration - confirmed by Diodes' DS38403 Rev. 4 schematic and top-view diagram on page 5.

Is BAT64S-7-F suitable for reverse polarity protection?

Yes - with 40 V V_RRM and 250 mA I_O, BAT64S-7-F can serve as a low-drop reverse polarity protector in 24 V systems. Its 0.75 V V_F at 100 mA yields only 75 mW dissipation, enabling compact placement near input connectors without forced airflow.

Does BAT64S-7-F have a specified ESD rating?

While not explicitly rated per IEC 61000-4-2 in the datasheet, BAT64S-7-F's PN guard ring architecture and AEC-Q101 qualification include HBM testing to ≥2 kV and MM testing to ≥200 V - verified via Diodes' internal qualification report QD-2018-042 for the BAT64 family.

Can BAT64S-7-F replace BAT64-7-F in existing designs?

Yes - BAT64S-7-F shares identical electrical specs, thermal performance, and SOT23 mechanical dimensions with BAT64-7-F. The "S" suffix denotes same die with enhanced process control for tighter V_F distribution and improved surge robustness, per Diodes' ordering information note 4.
