Product details
Overview
BAT64T5Q-13-F from Diodes Incorporated is a surface-mount Schottky barrier diode in SOD523 package, rated for 40 V peak reverse voltage, 250 mA continuous forward current, and 0.725 V max forward voltage at 100 mA. It features 5 ns reverse recovery time, 6 pF junction capacitance at 5 V, and PN junction guard ring for transient protection-used in automotive power rail clamping and high-frequency signal demodulation.
For engineers reviewing the BAT64T5Q-13-F datasheet, BAT64T5Q-13-F pinout, BAT64T5Q-13-F application, or BAT64T5Q-13-F equivalent, key selection criteria include low VF at high IF, ultra-small footprint compatibility with dense PCB layouts, AEC-Q101 qualification for automotive use, and transient robustness via integrated guard ring.
Technical Context
This Schottky diode employs a platinum-silicide or similar low-barrier metal-semiconductor junction to achieve fast switching (tRR ≤ 5 ns) and low forward conduction loss. Its SOD523 package enables integration into space-constrained automotive sensor modules and RF detector circuits where parasitic inductance must be minimized.
The PN junction guard ring structure provides enhanced ESD and transient immunity without external components, while the 40 V VRRM rating supports 24 V automotive supply rail protection and 12 V logic-level signal clamping applications under load dump conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 40 V - Withstands up to 40 V reverse bias without breakdown; suitable for 24 V system rail clamping. |
| IF Continuous | 250 mA - Supports moderate-power signal path rectification or biasing in compact sensor interfaces. |
| VF Max | 0.725 V @ 100 mA - Minimizes conduction loss and self-heating in battery-powered or thermally constrained designs. |
| tRR | 5.0 ns - Enables operation in >100 MHz RF detection and high-speed switching applications. |
| CT | 6 pF @ 5 V - Low junction capacitance preserves signal integrity in UHF receiver front-ends and antenna switch paths. |
| IR Max | 2.0 µA @ 40 V - Ensures minimal leakage in precision analog signal routing and low-power standby modes. |
| Polarity | Cathode band marked - Unambiguous orientation for automated placement and visual inspection on SMT lines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54T3G | Higher VF (0.95 V max @ 100 mA); SOT-23 package (3.0 × 1.4 mm) | Less suitable for ultra-dense layouts; higher conduction loss in battery-sensitive apps | Select when board space permits larger package and higher surge current (IFSM = 2 A) is required. |
| BAT54CW-7-F | Same SOD-323 package (1.7 × 1.3 mm); VF = 0.33 V typ @ 10 mA but IR = 10 µA @ 30 V | Higher leakage limits use in <1 µA standby circuits; slightly larger footprint than SOD523 | Select when lower VF at low IF is prioritized over leakage and miniaturization. |
Compared with SBAT54T3G and BAT54CW-7-F, BAT64T5Q-13-F delivers the smallest footprint (SOD523), lowest leakage (2 µA max), and best balance of VF and tRR for space- and power-constrained automotive and RF applications.

FAQ
What is the maximum junction temperature for BAT64T5Q-13-F?
The junction and storage temperature range is -65°C to +150°C. At ambient temperatures above 75°C, power dissipation must be derated linearly from 250 mW using RθJA = 500°C/W, reaching zero dissipation at 125°C ambient per the published derating curve.
Is BAT64T5Q-13-F compatible with lead-free reflow soldering profiles?
Yes. The device uses matte tin finish over alloy 42 leadframe and is qualified for standard Pb-free reflow profiles (J-STD-020, peak 260°C). Its moisture sensitivity level is 1, eliminating bake requirements prior to assembly.
Does BAT64T5Q-13-F have a specified ESD rating?
No specific HBM or CDM ESD rating is published in the datasheet. However, the integrated PN junction guard ring provides inherent transient suppression per ISO 10605 and IEC 61000-4-2, validated through AEC-Q101 stress testing including human-body model-like surges.
Can BAT64T5Q-13-F replace BAT54 in existing designs?
Only with layout revision: BAT64T5Q-13-F uses SOD523 (1.25 × 0.85 mm), while BAT54 uses SOT-23 (3.0 × 1.4 mm). Electrical substitution is viable for VRRM/IF requirements, but the smaller footprint demands updated stencil and placement files; VF and tRR are comparable or improved.
