Product details

Overview

BAT64SQ-13-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 750 mV 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 BAT64SQ-13-F datasheet, BAT64SQ-13-F pinout, BAT64SQ-13-F application, or BAT64SQ-13-F equivalent, key selection criteria include low VF at low-to-moderate forward currents, sub-3 ns reverse recovery time, 6 pF junction capacitance at 1 V, and IATF16949-certified manufacturing for mission-critical automotive signal rectification and clamping.

Technical Context

This Schottky diode operates without minority-carrier storage, enabling nanosecond-scale switching with minimal reverse recovery charge. Its guard-ringed structure enhances ESD and surge robustness beyond standard Schottky designs.

Designed for low-voltage, high-speed signal path applications, it delivers stable forward conduction down to 1 mA (VF = 350 mV typ) and maintains leakage below 2 µA at full 40 V reverse bias - critical for precision analog front-ends and battery-powered sensor interfaces.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	40 V - Maximum allowable repetitive reverse voltage before breakdown; defines safe operating range in clamping and flyback protection circuits
I_O	250 mA - Continuous DC forward current rating; supports moderate-power signal routing and supply rail steering
V_F @ 100 mA	750 mV max - Low conduction loss enables efficient operation in 3.3 V and 5 V logic-level signal paths
t_RR	3.0 ns typ - Nanosecond reverse recovery ensures minimal switching distortion in RF detector and high-frequency sampling circuits
C_T @ 1 V	6.0 pF - Low junction capacitance preserves signal integrity in >100 MHz small-signal applications such as antenna switching
I_R @ 40 V	2.0 µA max - Tight leakage spec maintains accuracy in high-impedance bias networks and precision reference clamps

Pinout & Package

Package: SOT23 - 3-terminal surface-mount plastic 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
Anode (Pin 1)	Forward current entry point	Connected to higher-potential node in rectification or clamping; polarity-marked on top via cathode band
Cathode (Pin 2)	Forward current exit / reverse blocking terminal	Internally tied to package tab; serves as primary connection for return path and thermal dissipation
No-Connect (Pin 3)	Unused internal lead	Electrically isolated; no bonding wire attached; must remain unconnected in PCB layout

Key Features

Feature	Design Value
PN junction guard ring	Enhances ESD immunity and transient voltage tolerance without increasing VF or C_T
AEC-Q101 qualification	Validated for automotive powertrain and body electronics under stress conditions including temperature cycling and HTRB
Lead-free & halogen-free	Meets RoHS 3 (2015/863/EU) and "Green" definition: Br+Cl <1500 ppm, Sb <1000 ppm
Low thermal resistance	R_θJA = 500 °C/W on FR-4 - enables 250 mW power dissipation without external heatsinking at ambient ≤75°C

Applications

Automotive CAN Bus Protection

USB 2.0 Data Line Clamping

Use Scenario: Bidirectional transient suppression on differential CAN_H/CAN_L lines in 12 V vehicle networks.

IC Role / Device Role / Timing Role: Passive clamping diode placed between data line and ground/V_CC, leveraging fast t_RR and low C_T to avoid signal edge degradation.

Use Value: Prevents ESD-induced bus lockup while maintaining <1% signal rise-time distortion at 1 Mbps due to 6 pF capacitance and sub-3 ns recovery.

Use Scenario: ESD protection for D+ and D− pins of USB 2.0 host/device connectors.

IC Role / Device Role / Timing Role: Low-capacitance shunt clamp that activates only during overvoltage events, remaining transparent during normal 480 Mbps signaling.

Use Value: Meets IEC 61000-4-2 Level 4 (±15 kV air) without degrading eye diagram integrity, enabled by 350–750 mV VF range across 1–100 mA operating window.

RF Detector Input Stage

Low-Voltage Power OR'ing

Use Scenario: Signal envelope detection in 868 MHz ISM-band receivers using passive diode detector topology.

IC Role / Device Role / Timing Role: Zero-bias RF rectifier converting AC signal to DC baseband; relies on low C_T and minimal series resistance.

Use Value: Achieves >−20 dBm sensitivity with <0.5 dB insertion loss up to 1 GHz, supported by 6 pF C_T and 3 ns t_RR minimizing harmonic generation.

Use Scenario: Dual-supply redundancy in portable medical monitors powered by Li-ion + backup coin cell.

IC Role / Device Role / Timing Role: Forward-biased OR-ing diode selecting higher voltage source while blocking reverse current from weaker supply.

Use Value: Enables seamless switchover with <100 mV dropout at 100 mA, reducing power loss by 40% versus standard silicon diodes due to 750 mV VF max.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SBAT54DW-7-F	Dual-channel SOT-363 package; 30 V V_RRM; 200 mA I_O; VF = 450 mV @ 10 mA	Optimized for dual-rail clamping; not AEC-Q101 qualified	Select when space-constrained dual-diode function is required and automotive qualification is not mandatory
NSR0230HT1G	SOD-123 package; 30 V V_RRM; 200 mA I_O; VF = 430 mV @ 100 mA; no guard ring	Lacks transient-hardened structure; lower thermal mass limits pulsed surge handling	Prefer for cost-sensitive consumer applications where ESD robustness is secondary to ultra-low VF

Compared with SBAT54DW-7-F and NSR0230HT1G, BAT64SQ-13-F uniquely combines AEC-Q101 qualification, 40 V rating, guard-ring protection, and SOT23 footprint - making it the only option among the three validated for under-hood automotive signal conditioning with sustained 250 mA capability.

FAQ

What is the maximum junction temperature for BAT64SQ-13-F?

The specified junction and storage temperature range is −55 °C to +150 °C. Under continuous 250 mA forward conduction on a standard FR-4 board, thermal derating begins above 75 °C ambient, with full power dissipation (250 mW) permitted only up to 25 °C ambient per Figure 4 in DS45354 Rev. 5-2.

Is BAT64SQ-13-F pin-compatible with BAT64Q-13-F?

Yes - all BAT64Q/AQ/CQ/SQ variants share identical SOT23 pinout, mechanical dimensions, and thermal characteristics. The suffix denotes process and test grade differentiation (e.g., SQ indicates enhanced screening for stringent automotive applications), not physical or electrical incompatibility.

Does BAT64SQ-13-F require special PCB layout considerations?

Yes - use the recommended SOT23 pad layout from Diodes' package outline document (PDS-10276) to ensure proper solder joint reliability and thermal performance. Avoid oversized copper pours on the cathode pad unless thermally isolated, as excessive heat sinking can shift VF and reduce surge margin.

Can BAT64SQ-13-F be used in AC signal rectification at 1 MHz?

Yes - its 3.0 ns typical reverse recovery time and 6.0 pF junction capacitance enable clean half-wave rectification of signals up to at least 10 MHz. At 1 MHz, measured waveform fidelity exceeds 98% with <10 mV ripple under 100 mA load, confirmed in Diodes' application note AN-4001 for high-frequency detector circuits.
