Product details
Overview
BAT54CQ-7-F from Diodes Incorporated is a 30 V, 200 mA surface-mount Schottky barrier diode in SOT23 package, featuring 800 mV max forward voltage at 100 mA, 2 µA max reverse leakage at 25 V, and 5 ns reverse recovery time; used for polarity protection and high-frequency clamping in automotive power management circuits.
For engineers reviewing the BAT54CQ-7-F datasheet, BAT54CQ-7-F pinout, BAT54CQ-7-F application, or BAT54CQ-7-F equivalent, key selection criteria include low VF for efficiency-critical 12 V rail protection, AEC-Q101 qualification for automotive deployment, SOT23 thermal resistance (RθJA = 500 °C/W), and guard-ring-enhanced ESD robustness.
Technical Context
This dual-anode common-cathode Schottky diode integrates two independent junctions sharing one cathode terminal, enabling compact dual-path rectification or level-shifting in space-constrained PCB layouts. Its PN junction guard ring suppresses transient-induced latch-up and improves ESD survivability per IEC 61000-4-2 Level 4.
The device operates across –55 °C to +150 °C with 200 mW power dissipation limit on FR-4 board, and exhibits 10 pF capacitance at 1 V reverse bias-critical for RF detector and high-speed signal routing applications where parasitic C must remain below 12 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - supports 12 V automotive systems with 2.5× safety margin against load-dump transients |
| IO | 200 mA - sufficient for sensor supply rail protection and low-power logic-level translation |
| VF Max | 800 mV @ 100 mA - minimizes conduction loss in always-on battery backup paths |
| IR Max | 2 µA @ 25 V - ensures negligible standby current in energy-sensitive telematics modules |
| tRR | 5 ns - enables clean switching in >10 MHz clock line clamping and RF envelope detection |
| CT | 10 pF @ 1 V - maintains signal integrity in 2.4 GHz ISM band front-end bias networks |
| RθJA | 500 °C/W - requires minimal copper pour for thermal compliance in sealed automotive ECUs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54CWTBG | Same SOT23-3 package, 30 V VRRM, but 300 mA IO rating and 350 mV typ VF at 10 mA | Higher surge current capability suits 12 V ignition coil driver flyback clamping | Select when peak IF > 200 mA required; verify thermal margin with RθJA = 420 °C/W |
| BAT54CW-7-F | Non-automotive grade; lacks AEC-Q101 qualification and guard ring; identical electrical specs otherwise | Restricted to consumer-grade portable electronics with no ESD or reliability certification needs | Choose only for cost-sensitive non-automotive designs where PPAP and transient immunity are not mandated |

FAQ
What is the maximum continuous forward current rating for BAT54CQ-7-F?
The BAT54CQ-7-F has a rated average rectified output current (IO) of 200 mA at TA = +25°C on a standard FR-4 PCB with recommended pad layout. Derating is required above +25°C ambient per the 500 °C/W thermal resistance curve, reaching 100 mA at +75°C ambient.
Is BAT54CQ-7-F suitable for bidirectional signal clamping applications?
No-BAT54CQ-7-F is a unidirectional dual-anode Schottky diode with a common cathode; it conducts only from either anode to cathode. For bidirectional clamping, a dual-common-anode or TVS diode such as D3V3M1U2LP is required.
Does BAT54CQ-7-F meet automotive ESD requirements per ISO 10605?
Yes-the integrated PN junction guard ring provides enhanced ESD robustness, and the device is AEC-Q101 qualified, which includes testing to ISO 10605 (25 kV air, 30 kV contact discharge) as part of its qualification protocol for automotive applications.
Can BAT54CQ-7-F be used in place of BAT54CWTBG in a new design?
Only if AEC-Q101 qualification, PPAP documentation, and guard-ring ESD protection are not required. BAT54CWTBG lacks automotive qualification and guard ring; substituting it risks non-compliance in automotive applications and reduced transient immunity in harsh environments.
