Product details

Overview

BAT54V-7 from Diodes Incorporated is a surface-mount Schottky barrier diode array in SOT-563 package, featuring dual anode–cathode configuration with one NC terminal, 30 V reverse voltage rating, 200 mA continuous forward current, and ultra-low 240–500 mV forward voltage at 0.1–100 mA. It serves as a high-speed clamping or steering diode in USB data line protection and low-voltage DC-DC converter feedback paths.

For engineers reviewing the BAT54V-7 datasheet, BAT54V-7 pinout, BAT54V-7 application, or BAT54V-7 equivalent, key selection criteria include its 5 ns reverse recovery time, 10 pF junction capacitance at 1 V, 2.0 µA reverse leakage at 25 V, thermal resistance of 833 °C/W, and suitability for space-constrained portable electronics requiring fast switching and ESD-hardened signal routing.

Technical Context

The BAT54V-7 integrates two independent Schottky diodes sharing a common cathode connection (C1–C2) and isolated anodes (A1–A2), with a non-connected (NC) terminal. Its PN junction guard ring structure provides transient suppression and meets IEC 61000-4-2 Level 4 ESD immunity without external components.

This device operates across –65 °C to +125 °C and derates linearly above +25 °C ambient, delivering 150 mW power dissipation on standard FR-4 PCBs. Its 300 mA repetitive peak forward current supports brief inrush handling in hot-swap circuits.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SBAT54DW-7-F	Same SOT-563 package, but dual common-anode configuration (not common-cathode); V_F = 320 mV @ 10 mA	Requires circuit redesign to accommodate anode-referenced topology; unsuitable for cathode-tied feedback networks	Select only when existing layout uses common-anode routing or requires reverse-polarity clamping
BAT54C-7-F	SOT-23 package (3-pin), common-cathode dual diode; same electrical specs but larger footprint (3.0 × 1.4 mm) and no NC terminals	Lacks space-saving advantage; incompatible with fine-pitch SOT-563 land patterns	Choose for legacy board reuse where SOT-23 pads exist and area is not constrained

Compared with SBAT54DW-7-F and BAT54C-7-F, the BAT54V-7 uniquely delivers common-cathode dual diode functionality in the smallest standardized footprint with verified ESD guard ring performance-making it optimal for new designs prioritizing miniaturization and integrated transient protection.

FAQ

What is the function of the two NC terminals in the BAT54V-7 SOT-563 package?

The two NC (No Connect) terminals in the BAT54V-7 are physically present but electrically unconnected to any die structure. They serve mechanical stabilization and thermal mass balancing roles within the molded SOT-563 package. Per Diodes' AP02002 outline drawing, these pins must remain unattached in PCB layout to prevent solder bridging or unintended parasitic coupling that could degrade ESD performance or signal integrity.

Can BAT54V-7 be used in place of BAT54A-7 or BAT54S-7 in existing designs?

No-BAT54V-7 has a unique common-cathode dual-diode configuration with two NC pins, whereas BAT54A-7 is common-anode and BAT54S-7 is series-connected. Pin compatibility is absent: BAT54A-7 uses SOT-23 with pins 1=A1, 2=C, 3=A2; BAT54V-7 uses SOT-563 with pins A1/C1/NC/NC/A2/C2. Substitution would require full schematic and layout revision.

Does the PN junction guard ring affect the device's forward conduction behavior?

No-the PN guard ring in BAT54V-7 is a separate, lightly doped diffusion surrounding the active Schottky junction and does not participate in forward conduction. It remains reverse-biased during normal operation and only conducts during ESD transients to shunt current away from the sensitive metal–semiconductor interface, preserving the specified 240–500 mV forward voltage and 5 ns t_rr under DC and switching conditions.

What is the maximum allowable PCB trace width for the cathode (C1/C2) connection in high-current pulse scenarios?

For 300 mA repetitive peak forward current (I_FRM), Diodes recommends ≥0.3 mm (12 mil) trace width on 1 oz copper with 10 mm length to limit temperature rise to <10 °C. The shared cathode path must be routed as a single low-inductance node-splitting C1 and C2 traces introduces imbalance and may cause unequal current sharing or localized heating exceeding the 150 mW PD rating.
