Product details

Overview

BAT64-7-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 fast 3.0 ns reverse recovery time, 6.0 pF junction capacitance at 1 V, and PN junction guard ring for transient protection-used in DC-DC converter output rectification and low-voltage signal clamping.

For engineers reviewing the BAT64-7-F datasheet, BAT64-7-F pinout, BAT64-7-F application, or BAT64-7-F equivalent, key selection criteria include forward voltage drop at load current, reverse leakage under blocking bias, thermal resistance (500 °C/W), and SOT23 footprint compatibility with high-density PCB layouts.

Technical Context

This Schottky diode leverages a low-barrier metal-semiconductor junction to achieve sub-0.75 V forward conduction at 100 mA while maintaining 40 V reverse standoff. Its 3.0 ns t_RR enables operation in switching frequencies up to ~100 MHz in clamp and freewheeling roles.

The integrated PN junction guard ring suppresses edge breakdown under transient overvoltage, improving robustness without increasing VF or capacitance. Thermal performance is defined for FR-4 mounting: 250 mW power dissipation derates linearly above 25 °C ambient per the published curve.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	40 V - Maximum repetitive reverse voltage before breakdown; sets upper limit for blocking applications like buck converter freewheeling.
I_O	250 mA - Continuous DC forward current rating; defines steady-state power delivery capability in rectifier paths.
V_F @ 100 mA	0.75 V max - Forward voltage drop at nominal load; directly impacts conduction loss and thermal rise in low-voltage rails.
t_RR	3.0 ns - Reverse recovery time; enables efficient high-frequency switching in SMPS and signal routing.
C_T @ 1 V	6.0 pF - Junction capacitance at 1 V reverse bias; critical for RF detector and high-speed clamp bandwidth.
I_R @ 40 V	2.0 µA max - Reverse leakage current at full rated blocking voltage; affects standby power in battery-powered systems.
R_θJA	500 °C/W - Junction-to-ambient thermal resistance on FR-4; determines temperature rise under 250 mW dissipation.

Pinout & Package

Package: SOT23 - 3-terminal plastic surface-mount package with standard leadframe geometry, 0.008 g mass, UL 94V-0 molding compound, and matte tin-plated Alloy 42 leads.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Pin 1)	Forward current entry point	Connected to higher-potential node in rectifier or clamp configuration; polarity marked by cathode band on package top view.
Cathode (Pin 2)	Forward current exit / reverse blocking terminal	Connected to lower-potential node; carries full reverse voltage during off-state; marked by cathode band on package.
NC / Heat Sink (Pin 3)	No internal connection	Unused terminal; electrically isolated; may be grounded or left floating per layout requirements-no thermal function in this variant.

Key Features

Feature	Design Value
Low turn-on voltage	0.35 V typical at 1 mA - Enables efficient rectification in sub-1 V supply domains such as USB OTG and energy harvesting.
Fast switching	3.0 ns t_RR - Reduces switching loss and ringing in >1 MHz DC-DC converters and RF envelope detectors.
PN junction guard ring	Integrated edge termination - Suppresses premature avalanche at junction periphery, improving surge tolerance without VF penalty.
AEC-Q101 qualified	Automotive-grade reliability - Validated for temperature cycling, HTRB, and ESD per AEC-Q101 Rev D, supporting under-hood and infotainment use.

Applications

DC-DC Converter Output Rectification

Low-Voltage Signal Clamping

Use Scenario: Used as synchronous rectifier or freewheeling diode in 3.3 V/5 V buck converters powering microcontrollers and sensors.

IC Role / Device Role: Schottky rectifier providing low-loss unidirectional current path during switch off-time.

Use Value: 0.75 V V_F at 100 mA reduces conduction loss by ~40% vs. standard silicon diodes, lowering thermal load in compact power modules.

Use Scenario: Protects ADC inputs and logic pins from ESD transients and overvoltage spikes in portable instrumentation.

IC Role / Device Role: Clamp diode shunting excess voltage to rail or ground before damage threshold is exceeded.

Use Value: 3.0 ns t_RR and 6.0 pF C_T preserve signal integrity up to 100 MHz while limiting clamping voltage to <0.8 V above rail.

RF Detector Circuit

Reverse Polarity Protection

Use Scenario: Demodulates AM signals in low-power wireless sensor nodes using envelope detection topology.

IC Role / Device Role: Zero-bias RF detector diode converting RF amplitude to DC voltage.

Use Value: Low C_T (6.0 pF) and minimal series resistance enable sensitivity down to -20 dBm at 900 MHz.

Use Scenario: Placed in series with V_IN to prevent damage from accidental reverse battery connection in industrial controllers.

IC Role / Device Role: Series protection diode conducting only during correct polarity insertion.

Use Value: 250 mA I_O and 40 V V_RRM support 12 V/24 V systems; low V_F minimizes voltage drop in normal operation.

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 SOT23 package; 30 V V_RRM, 200 mA I_O, 0.8 V V_F @ 100 mA, 2.5 ns t_RR	Lower voltage rating limits use to ≤3.3 V systems; faster t_RR suits higher-frequency RF detection.	Select when 30 V blocking suffices and sub-3 ns recovery is prioritized over current capacity.
NSR0230HT1G	Same SOT23; 30 V V_RRM, 200 mA I_O, 0.35 V V_F typ @ 10 mA, but 1.0 V max @ 100 mA	Lower V_F at light loads improves efficiency in battery monitoring; higher V_F at full load increases conduction loss.	Prefer for ultra-low-power wake-up circuits where I_F rarely exceeds 10 mA.

Compared with SBAT54LT1G and NSR0230HT1G, BAT64-7-F delivers superior 40 V blocking margin and tighter V_F consistency across 1–100 mA, making it optimal for 5–12 V industrial power rails requiring both robustness and predictable loss.

FAQ

What is the maximum junction temperature for BAT64-7-F?

The junction and storage temperature range is specified as –65 °C to +150 °C. Under continuous 250 mA operation with 0.75 V forward drop, junction temperature rise depends on PCB copper area and ambient conditions; with standard FR-4 layout, T_J remains below 125 °C at 25 °C ambient due to 500 °C/W R_θJA.

Is BAT64-7-F suitable for automotive applications?

Yes-BAT64-7-F is qualified to AEC-Q101 standards, including stress testing for temperature cycling, high-temperature reverse bias, and ESD. Its SOT23 package, guard ring structure, and –65 °C to +150 °C operating range meet requirements for engine control units, body electronics, and infotainment systems.

How does the PN junction guard ring improve reliability?

The guard ring mitigates electric field crowding at the semiconductor edge, preventing premature avalanche breakdown during voltage transients. This allows the diode to withstand repeated 2.1 A non-repetitive surge events (8.3 ms half-sine) without degradation, extending service life in noisy industrial environments.

Can BAT64-7-F replace BAT54 in existing designs?

Yes, with verification: both use SOT23 and share anode/cathode pinout, but BAT64-7-F offers 40 V V_RRM (vs. 30 V for BAT54), 250 mA I_O (vs. 200 mA), and guaranteed 0.75 V V_F max at 100 mA. Layout compatibility is confirmed; electrical validation is recommended if operating near 30–40 V blocking limits.
